Referring to fig. 1 and 2, the present invention provides a liquid cooled data processing system 100. The liquid cooling data processing system 100 can recover the heat generated by the liquid cooling data processing apparatus 130 during operation, so as to ensure the reliability of the operation of the liquid cooling data processing apparatus 130. Moreover, the heat of the recovered liquid cooling data processing device 130 can be used for urban heating, so that the resource can be reused, and the resource consumption is reduced. Of course, in other embodiments of the present invention, the heat of the liquid-cooled data processing apparatus 130 can also be directly dissipated to the external environment. It is understood that the liquid-cooled data processing system 100 of the present invention mainly cools the liquid-cooled data processing apparatus 130, and the heat source for recovering heat is the liquid-cooled data processing apparatus 130, but in other embodiments of the present invention, the liquid-cooled data processing system 100 of the present invention may also be used to cool an electronic device set or other heat sources with temperature and recover corresponding heat. The liquid-cooled data processing system 100 of the present invention will be described with reference to the cooling liquid-cooled data processing apparatus 130 as an example. Optionally, the liquid-cooled data processing apparatus 130 is a cabinet liquid-cooled device, but may be other devices capable of processing data.

It can be understood that, for data processing equipment such as a digital coin mining machine, a plurality of data processing equipment work in a centralized manner to dissipate heat, the heat dissipation system design is designed by referring to a liquid cooling system of a data center server, and the system adopts a constant temperature and constant pressure control strategy for heat loads, and the strategy is suitable for servers with relatively low power density and equivalent heat loads. However, the constant-voltage control cannot realize independent control of the operating temperature of each data processing device without interfering with the operation of other data processing devices, and thus, it cannot be guaranteed that each data processing device is in an optimal or normal operating state, which affects the use performance of the data processing device. The constant temperature control strategy is not suitable for the working mode that the data processing equipment is started, namely the power is instantly fully loaded, the control response is slow, and a plurality of data processing equipment are easy to be over-temperature protected and cannot work normally when being started simultaneously. Therefore, the present invention provides a novel liquid-cooled data processing system 100, and the specific structure of the liquid-cooled data processing system 100 will be described in detail below.

Referring to fig. 1 and 2, in one embodiment, a liquid-cooled data processing system 100 includes a temperature-controlled heat exchanging system 110, a heat dissipating system 120, and a liquid-cooled data processing apparatus 130.

The liquid cooling data processing device 130 is connected to the liquid supply inlet pipe 112 and the liquid supply return pipe 113.

The liquid-cooled data processing apparatus 130 is for flowing a cooling liquid. The temperature-controlled heat exchange system 110 can exchange heat between the cooling liquid in the liquid-cooled data processing apparatus 130 and the circulating liquid in the heat dissipation system 120. The liquid-cooled data processing device 130 absorbs the heat dissipated during the operation of the device through the cooling liquid, so that the temperature of the liquid-cooled data processing device 130 is reduced, and the reliability of the operation of the liquid-cooled data processing device 130 is ensured. The heat-absorbed cooling liquid exchanges heat with the circulating liquid in the heat dissipation system 120 through the temperature control heat exchange system 110, after heat exchange, the temperature of the cooling liquid is reduced, the liquid-cooled data processing device 130 can be cooled again, the heat is dissipated by the heat absorption circulating liquid through the heat dissipation system 120, and the liquid-cooled data processing system 100 is cooled and controlled in such a circulating manner. It is understood that the heat dissipation system 120 can directly dissipate heat to the external environment, or can use the heat for heating, such as heating or a structure requiring temperature rise.

Specifically, the temperature control heat exchange unit 111 in the temperature control heat exchange system 110 is connected to the liquid cooling data processing device 130 through the liquid supply inlet pipe 112 and the liquid supply return pipe 113, the temperature control heat exchange unit 111 conveys the cooling liquid to the liquid cooling data processing device 130 through the liquid supply inlet pipe 112, the cooling liquid, after absorbing the heat emitted by the liquid cooling data processing device 130, flows back to the temperature control heat exchange unit 111 through the liquid supply return pipe 113, and exchanges heat with the circulating liquid in the temperature control heat exchange unit 111, and the cooling liquid, after absorbing the cooling capacity of the circulating liquid, enters the liquid supply inlet pipe 112. Optionally, the temperature-controlled heat exchange unit 111 is a heat exchanger or other components capable of exchanging heat. The heat dissipation unit 121 in the heat dissipation system 120 is connected to the temperature-controlled heat exchange unit 111 through a heat exchange inlet pipe 122 and a heat exchange return pipe 123. After the heat of the circulating liquid in the heat dissipation unit 121 is dissipated, the circulating liquid enters the temperature control heat exchange unit 111 through the heat exchange inlet pipe 122 and exchanges heat with the cooling liquid in the temperature control heat exchange unit 111, and the circulating liquid absorbs the heat of the cooling liquid and then enters the heat exchange return pipe 123, and the heat of the circulating liquid is dissipated by the heat dissipation unit 121. Alternatively, the heat dissipation unit 121 is a heat sink or other components capable of dissipating heat. Optionally, the heat dissipation unit further includes a cooling device or system such as a cooling tower, a dry cooler, a fan, a heating device, and the like. Optionally, the heat dissipation unit is described as an example in conjunction with a fan in the present invention.

After the liquid cooling data processing devices 130 are connected to the liquid supply inlet pipe 112 and the liquid supply return pipe 113, one end of each liquid cooling data processing device 130 is connected to the liquid supply inlet pipe 112, the other end of each liquid cooling data processing device 130 is connected to the liquid supply return pipe 113, cooling liquid supplied from the liquid supply inlet pipe 112 enters each liquid cooling data processing device 130 and cools the liquid cooling data processing device 130, and the cooling liquid after heat absorption flows out of the liquid cooling data processing device 130 and enters the liquid supply return pipe 113. Optionally, the number of the liquid cooling data processing devices 130 is plural, and the plural liquid cooling data processing devices 130 are connected in parallel to the liquid supply inlet pipe 112 and the liquid supply return pipe 113. That is, one end of each liquid-cooled data processing device 130 is connected to the liquid supply inlet pipe 112, and the other end is connected to the liquid supply return pipe 113, and a plurality of liquid-cooled data processing devices 130 are arranged in parallel. The cooling liquid delivered by the liquid inlet pipe 112 enters each liquid-cooled data processing device 130, and cools the liquid-cooled data processing devices 130, and the cooling liquid after heat absorption flows out of the liquid-cooled data processing devices 130 and enters the liquid return pipe 113.

It should be noted that, no matter the number of the liquid-cooled data processing devices 130 is one or more, the flow direction of the cooling liquid is constant, and the cooling liquid flows from the liquid supply pipe 112 to the liquid supply return pipe 113 through the liquid-cooled data processing devices 130. Only when the number of the liquid-cooled data processing devices 130 is multiple, the cooling liquid in the liquid-cooled data processing device 112 enters each liquid-cooled data processing device 130 for cooling, and the cooled cooling liquid flows out of each liquid-cooled data processing device 130 and is collected in the liquid-supplying return pipe 113. The following description of the liquid-cooled data processing system 100 may be applied to the case of one liquid-cooled data processing apparatus 130, or to the case of a plurality of liquid-cooled data processing apparatuses 130, and the structures of the respective liquid-cooled data processing apparatuses 130 may be the same.

Specifically, the liquid cooling data processing apparatus 130 includes a plurality of data processing devices 131, a plurality of liquid cooling branches 134, a plurality of branch pumps 135, a liquid distribution pipeline 132, and a liquid collection pipeline 133, where the data processing device 131 includes a module control unit (not shown), the liquid distribution pipeline 132 is connected to the liquid supply inlet pipe 112, the liquid collection pipeline 133 is connected to the liquid supply return pipe 113, the plurality of liquid cooling branches 134 are connected in parallel to the liquid distribution pipeline 132 and the liquid collection pipeline 133, and form a cooling loop for flowing cooling liquid, the data processing device 131 is disposed in the liquid cooling branches 134 and is cooled by the liquid cooling branches 134, each liquid cooling branch 134 is provided with one branch pump 135, and the branch pump 135 is located between the liquid distribution pipeline 132 and the data processing device 131 and is used for controlling the flow rate of cooling liquid in the corresponding liquid cooling branch 134. The module control unit of the data processing device 131 is electrically connected to the branch pump 135 of the liquid cooling branch 134 corresponding to the data processing device 131, and the module control unit can independently control the branch pump 135 of the liquid cooling branch 134 corresponding to the module control unit according to the working temperature of the data processing device 131.

Optionally, the data processing apparatus 131 is installed at a position on the liquid cooling branch 134 to cool the data processing apparatus 131. Of course, in other embodiments of the present invention, the liquid cooling branch 134 may be disposed inside the data processing device 131, and both ends of the liquid cooling branch 134 are exposed out of the data processing device 131 for connecting the liquid separating pipeline 132 and the liquid collecting pipeline 133. Alternatively, the bypass pump 135 may be located inside the data processing apparatus 131, and may also be located outside the data processing apparatus 131. Alternatively, the data processing device 131 is a mining machine, but may be of other configurations capable of processing equipment. Alternatively, the plurality of data processing devices 131, i.e., the ore machines, form the liquid cooling data processing apparatus 130, i.e., the cabinet liquid cooling machine.

In the liquid-cooled data processing apparatus 130, the liquid distribution line 132 communicates with the liquid supply inlet pipe 112, the liquid collection line 133 communicates with the liquid supply return pipe 113, one end of the liquid-cooled branch line 134 communicates with the liquid distribution line 132, the other end communicates with the liquid collection line 133, and the plurality of liquid-cooled branch lines 134 are connected in parallel between the liquid distribution line 132 and the liquid collection line 133. Like this, divide liquid pipeline 132 can realize the reposition of redundant personnel of coolant liquid, with during coolant liquid reposition of redundant personnel reaches each liquid cooling branch 134, the data processing equipment 131 on the liquid cooling branch 134 can be cooled off to the coolant liquid flow through liquid cooling branch 134, reduces the temperature of data processing equipment 131 during operation. The heat absorbed coolant enters the liquid collecting pipes 133 through the liquid cooling branches 134, and the liquid collecting pipes 133 can collect the coolant in each liquid cooling branch 134 and convey the coolant to the liquid supply return pipe 113.

The liquid separating pipeline 132, the liquid cooling branch 134, the liquid collecting pipeline 133, the liquid supply inlet pipe 112, the liquid supply return pipe 113 and the temperature-controlled heat exchange unit 111 form a complete cooling loop. During cooling, the temperature-controlled heat exchange unit 111 conveys the heat-released cooling liquid to the liquid supply inlet pipe 112, and the cooling liquid is shunted to each liquid cooling branch 134 through the liquid supply inlet pipe 112, and after absorbing the heat of the data processing equipment 131 on the liquid cooling branch 134, the cooling liquid enters the liquid supply return pipe 113 through the liquid collection pipe 133, and then flows back to the temperature-controlled heat exchange unit 111.

Meanwhile, each liquid cooling branch 134 corresponds to one branch pump 135. The branch pump 135 is capable of adjusting the flow rate into the corresponding liquid cooling branch 134, thereby adjusting the cooling effect on the data processing device 131. The module control unit of each data processing apparatus 131 is electrically connected to the branch pump 135 of the corresponding liquid cooling branch 134. The module control unit is used for realizing independent control of each data processing device 131 in the liquid cooling data processing apparatus 130, and is used for controlling the data processing device to start, stop or reduce the frequency.

The module control unit can obtain the working temperature of the data processing device 131, and then control the opening degree of the branch pump 135 according to the working temperature to adjust the flow rate of the liquid cooling branch 134. As can be understood, when the working temperature of the data processing device 131 is higher, the module control unit controls the opening degree of the bypass pump 135 to increase, so as to increase the flow rate of the cooling liquid and ensure the cooling effect of the data processing device 131; when the working temperature of the data processing device 131 is low, the module control unit controls the opening degree of the bypass pump 135 to be small, so that the flow rate of the cooling liquid is reduced, and the use amount of the cooling liquid is reduced while the cooling effect of the data processing device 131 is ensured. Optionally, a bypass pump 135 is located between the tapping line 132 and the data processing device 131. Of course, the bypass pump 135 may also be located between the data processing device 131 and the sump line 133 in other embodiments of the invention.

When the liquid-cooling data processing system 100 of the above embodiment works, for the data processing device 131 with a higher actual temperature, the flow rate of the cooling liquid in the corresponding liquid-cooling branch 134 can be increased through the branch pump 135, and for the data processing device 131 with a lower working temperature, the flow rate in the corresponding liquid-cooling branch 134 can be reduced through the branch pump 135, thereby effectively solving the problem that the temperature of each data processing device cannot be independently controlled at present, and realizing independent control of the working temperature of different data processing devices 131 without interfering with the operation of other data processing devices 131, so that each data processing device 131 is at a better working temperature, and ensuring the usability of the data processing device 131.

In an embodiment, the temperature-controlled heat exchanging system 110 further includes a first water tank 140, the first water tank 140 is disposed on the liquid supply pipe 112 and located between the temperature-controlled heat exchanging unit 111 and the first liquid-cooled data processing apparatus 130, and the first water tank 140 is configured to store the cooling liquid output by the temperature-controlled heat exchanging unit 111. The first water tank 140 has a buffer storage function, and can buffer the cooling liquid output by the temperature control heat exchange unit 111. After the temperature control heat exchange unit 111 outputs the cooling liquid absorbing the cooling capacity, the cooling liquid enters the first water tank 140 through the liquid supply pipe 112, and then is respectively conveyed to each liquid cooling data processing device 130 from the first water tank 140 through the liquid supply pipe 112. The first tank 140 has a certain volume to store a certain amount of cooling fluid.

The first tank 140 is capable of storing a cooling fluid and stabilizing the constant pressure of the fluid-cooled data processing system 100. It can be understood that, because the first water tank 140 is connected between the temperature control heat exchanging unit 111 and the plurality of liquid-cooled data processing apparatuses 130, and the first water tank 140 is used to convey the cooling liquid to the plurality of liquid-cooled data processing apparatuses 130, the cooling liquid cached in the first water tank 140 can be respectively conveyed to each data processing device 131, thereby avoiding the problem of insufficient cooling liquid. Moreover, when the flow fluctuation or the temperature fluctuation occurs in the cooling liquid outputted from the temperature control heat exchange unit 111, the first water tank 140 can play a role of buffering, so as to prevent the cooling liquid from affecting the cooling of the liquid cooling data processing apparatus 130.

Meanwhile, the first water tank 140 can also play a role of pressure isolation, and can prevent the liquid supply pressure of the temperature control heat exchange unit 111 from influencing the distribution of the cooling liquid to each liquid cooling data processing device 130. Moreover, the first water tank 140 is an open water tank, that is, the first water tank 140 is an open structure and can be communicated with the external environment. Thus, the pressure of the coolant in the first water tank 140 is not fluctuated, and the stability of the whole system is ensured.

In an embodiment, the temperature-controlled heat exchanging system 110 further includes a second water tank 150, the second water tank 150 is disposed in the liquid supply return pipe 113 and located between the temperature-controlled heat exchanging unit 111 and the first liquid-cooled data processing apparatus 130, and the second water tank 150 is configured to store the cooling liquid output by each data processing apparatus 131. The second water tank 150 has a buffer storage function, and can buffer the cooling liquid output by the liquid cooling data processing apparatus 130. After the liquid cooling data processing device 130 outputs the cooling liquid absorbing heat, the cooling liquid enters the second water tank 150 through the liquid supply return pipe 113, and then is conveyed to the temperature control heat exchange unit 111 through the second water tank 150 through the liquid supply return pipe 113, and exchanges heat with the circulating liquid. The second tank 150 has a certain volume to store a certain amount of cooling liquid.

The second tank 150 is capable of storing cooling fluid and stabilizing the constant pressure of the fluid-cooled data processing system 100. It can be understood that, because the second water tank 150 is connected between the temperature control heat exchanging unit 111 and the plurality of liquid cooling data processing devices 130, the second water tank 150 stores the cooling liquid delivered by the plurality of liquid cooling data processing devices 130 and delivers the cooling liquid to the temperature control heat exchanging unit 111, so that the cooling liquid can be cached, and the problem of blockage caused by too much cooling liquid is avoided. Moreover, when the flow fluctuation or the temperature fluctuation occurs in the cooling liquid of each liquid cooling data processing apparatus 130, the second water tank 150 can play a role of buffering, and the cooling liquid is prevented from affecting the heat exchange of the temperature control heat exchange unit 111.

Meanwhile, the second water tank 150 can also play a role of pressure isolation, so that the influence of the liquid supply and return pressure of the temperature control heat exchange unit 111 on the distribution of the cooling liquid to each liquid cooling data processing device 130 can be prevented, the sudden rise of the liquid return temperature caused by the steep increase of the heat load when a plurality of liquid cooling data processing devices 130 are started can be avoided, the temperature rise of the cooling liquid output by the temperature control heat exchange unit 111 is further avoided, and the normal operation or the starting of the liquid cooling data processing devices 130 is ensured. Moreover, the second water tank 150 is an open water tank, that is, the second water tank 150 is an open structure and can be communicated with the external environment. Thus, the pressure of the coolant in the second tank 150 is not fluctuated, and the stability of the entire system is ensured.

Alternatively, the temperature controlled heat exchange system 110 may be provided with the first water tank 140 only in the liquid supply pipe 112. Alternatively, the temperature controlled heat exchange system 110 may be provided with the second water tank 150 only in the feed liquid return 113. Of course, in this embodiment, the temperature controlled heat exchange system 110 has a first water tank 140 disposed in the liquid supply pipe 112 and a second water tank 150 disposed in the liquid supply return pipe 113. Therefore, the pressure separation between the temperature control heat exchange unit 111 and the liquid cooling data processing device 130 can be realized, and the liquid supply and return pressure of the temperature control heat exchange unit 111 does not influence the distribution of the flow of the cooling liquid at the liquid cooling data processing device 130, so that the flow of the cooling liquid in each liquid cooling branch 134 is completely controlled by the branch pump 135, and the independent and controllable cooling of each data processing device 131 is realized.

Referring to fig. 1 and fig. 2, in an embodiment, the temperature control heat exchange system further includes a temperature control unit, the heat dissipation system further includes a control valve 124 and a first circulation pump 126 electrically connected to the temperature control heat exchange unit, the heat dissipation unit 121 at least includes a heat dissipation fan 125, the control valve 124 is disposed in the heat exchange inlet pipe 122, the first circulation pump 126 is disposed in the heat exchange return pipe 123, and the temperature control unit controls the control valve 124, the heat dissipation fan 125, and the first circulation pump 126 according to an actual liquid supply temperature of the coolant in the liquid supply inlet pipe 112.

The first circulation pump 126 and the control valve 124 are used to control the flow rate of the circulation fluid in the circulation loop. It is understood that the first circulation pump 126 may be provided only on the heat exchange return pipe 123, or the control valve 124 may be provided only on the heat exchange inlet pipe 122. In the present embodiment, both the first circulation pump 126 and the control valve 124 are provided. The temperature control unit can acquire an actual liquid supply temperature of the liquid coolant supplied into the liquid supply pipe 112, and control the heat dissipation amount of the heat dissipation unit according to the actual liquid supply temperature. The detection of the actual liquid supply temperature is mentioned later.

The target liquid supply temperature is set according to the working temperature of the data processing equipment, when the actual liquid supply temperature is lower than the target liquid supply temperature, the temperature control unit controls the heat dissipation fan 125 to reduce the heat dissipation capacity, and controls the valve 124 and the first circulating pump 126 to reduce the flow of circulating liquid in the circulating loop, so that the actual liquid supply temperature of the cooling liquid can be controlled at the target liquid supply temperature, the system can meet the cooling requirement of the data processing equipment in the most energy-saving state, and meanwhile, the liquid inlet temperature reasonability of the cooling liquid of the data processing equipment 131 is guaranteed. When the actual liquid supply temperature is higher than the target liquid supply temperature, the temperature control unit controls the heat dissipation fan 125 to increase the heat dissipation capacity, controls the first circulation pump 126 and the control valve 124 to increase the flow rate of the circulation liquid in the circulation loop, so as to ensure the cooling effect of the cooling liquid, and reduce the actual liquid supply temperature of the cooling liquid to the target liquid supply temperature.

Referring to fig. 1 and 2, in an embodiment, the temperature-controlled heat exchange system 110 further includes a second circulation pump 114 electrically connected to the temperature-controlled control unit, and a liquid level sensor 160, where the liquid level sensor 160 is disposed in the first water tank 140 and/or the second water tank 150 and is used for detecting a liquid level height of the first water tank 140 and/or the second water tank 150, and the temperature-controlled control unit controls a total liquid circulation amount of the temperature-controlled heat exchange unit 111 according to the liquid level height detected by the liquid level sensor 160.

Alternatively, the level sensor 160 may be provided only in the first water tank 140. Alternatively, the level sensor 160 may be provided only in the second water tank 150. Of course, in other embodiments of the present invention, the level sensor 160 may be disposed in both the first tank 140 and the second tank 150. In the present invention, the liquid level sensor 160 is provided in the second tank 150 only as an example.

Second circulating pump 114 sets up in control by temperature change heat transfer unit's inside, for the circulation flow of coolant liquid provides power, guarantees that the coolant liquid can be in cooling circuit circulation flow, and this second circulating pump 114 is connected with the control by temperature change control unit electricity, controls the circulating pump work through the control by temperature change control unit. The temperature control unit controls the second circulation pump 114 to adjust the flow rate of the cooling liquid in the liquid supply return pipe according to the liquid level in the second water tank 150 detected by the liquid level sensor 160.

It will be appreciated that the sum of the flow rates of all the bypass pumps should in principle be equal to the circulation flow rate of the cooling liquid of the cooling circuit through the temperature controlled heat exchange unit 111. The liquid level sensor 160 detects the liquid level of the cooling liquid in the second water tank 150, and the liquid level fed back by the liquid level sensor 160 controls the operating frequency of the second circulating pump 114, i.e. controls the total liquid circulation amount on the side of the temperature control heat exchange unit 111, thereby ensuring that the total liquid circulation amount on the side of the temperature control heat exchange unit 111 and the total liquid circulation amount in all pipelines are in a balanced state. Therefore, the situation that more and more cooling liquid in one water tank and less cooling liquid in the other water tank are generated can be avoided, the circulating balance of the cooling liquid in the whole system is ensured, and the working reliability of the system is ensured.

Specifically, when the amount of the cooling liquid in the second water tank 150 is large and the amount of the cooling liquid in the first water tank 140 is small, the liquid level sensor 160 feeds back the liquid level to the temperature control unit, and the temperature control unit controls the second circulation pump 114 to increase the flow rate of the cooling liquid in the liquid supply return pipe 113. When the amount of the cooling liquid in the first water tank 140 is larger and the amount of the cooling liquid in the second water tank 150 is smaller, the liquid level sensor 160 feeds the liquid level back to the temperature control unit, and the temperature control unit controls the second circulation pump 114 to reduce the flow rate of the cooling liquid in the liquid supply return pipe 113.

In an embodiment, the temperature-controlled heat exchanging system 110 further includes a first detecting sensor 136, the first detecting sensor 136 is disposed on the liquid supply pipe 112 and located between the temperature-controlled heat exchanging unit 111 and the first liquid-cooled data processing apparatus 130, and the first detecting sensor 136 is configured to detect a temperature of the cooling liquid supplied to the liquid-cooled data processing apparatus 130. The first detection sensor 136 is located at the output end of the first water tank 140, and the first detection sensor 136 can detect the temperature of the cooling liquid output by the first water tank 140, that is, detect the actual liquid supply temperature to the liquid cooling data processing apparatus 130, so as to ensure the cooling effect of the cooling liquid on the liquid cooling data processing apparatus 130.

After the actual liquid supply temperature is detected by the first detection sensor 136, the actual liquid supply temperature is fed back to the temperature control unit, and the target liquid supply temperature of the cooling liquid is stored in the temperature control unit. When the actual liquid supply temperature is lower than the target liquid supply temperature, the temperature control unit controls the heat dissipation fan 125 to reduce the heat dissipation amount, and controls the valve 124 and/or the first circulating pump 126 to reduce the flow rate of the circulating liquid in the circulating loop, so that the actual liquid supply temperature of the cooling liquid can be controlled at the target liquid supply temperature, the system can meet the cooling requirement of the data processing equipment 131 in the most energy-saving state, and meanwhile, the liquid inlet temperature of the cooling liquid of the data processing equipment 131 is guaranteed to be reasonable. When the actual liquid supply temperature exceeds the target liquid supply temperature, the temperature control unit controls the heat dissipation fan 125 to increase the heat dissipation capacity, controls the first circulation pump 126 and/or the control valve 124 to increase the flow rate of the circulation liquid in the circulation loop, so as to ensure the cooling effect of the cooling liquid, and reduces the actual liquid supply temperature of the cooling liquid to the target liquid supply temperature. Thus, the cooling liquid can effectively cool the data processing device 131, so as to avoid high-temperature operation of the data processing device 131 and ensure the service performance of the data processing device 131.

In an embodiment, the temperature control heat exchange system 110 further includes a second detection sensor 137 and a third detection sensor 138, and the second detection sensor 137 and the third detection sensor 138 are respectively disposed at two sides of the second water tank 150. The second detecting sensor 137 is located between the liquid-cooled data processing apparatus 130 and the second water tank 150, and is configured to detect the temperature of the cooling liquid after the heat absorption output by the liquid-cooled data processing apparatus 130. The third detection sensor 138 is located between the second water tank 150 and the temperature-controlled heat exchange unit 111, and is configured to detect a temperature of the cooling liquid output from the second water tank 150 to the temperature-controlled heat exchange unit 111. The temperature of the coolant output from the temperature-controlled heat exchange unit 111 can be accurately controlled by detecting the temperature of the coolant by the second detection sensor 137 and the third detection sensor 138.

It is understood that the second detection sensor 137 and the third detection sensor 138 detect the same temperature without the second water tank 150. After the second water tank 150 is arranged, after the cooling liquid is buffered by the second water tank 150, a certain temperature difference exists between the cooling liquid detected by the second detection sensor 137 and the cooling liquid detected by the third detection sensor 138, so that fluctuation of the temperature of the cooling liquid output by the temperature control heat exchange unit 111 caused by sudden change of the temperature of the cooling liquid after heat absorption is avoided.

Optionally, the liquid-cooled data processing apparatus 130 further includes a cabinet housing, and the cabinet housing covers the plurality of data processing devices 131, the liquid-cooled branch 134, the liquid collecting pipeline 133, and the liquid distributing pipeline 132 of the liquid-cooled data processing apparatus 130, so as to prevent the data processing devices 131 from being exposed and ensure the usability. Moreover, the liquid cooling data processing apparatus 130 further includes a frame body, and the frame body has an installation space arranged layer by layer for installing the data processing device 131, so that the data processing device 131 is arranged in a stacked manner, the occupied space is reduced, and the space utilization rate is improved.

In the liquid-cooled data processing system 100, the temperature control heat exchange system 110 is used to realize the heat exchange between the plurality of liquid-cooled data processing devices 130 and the heat dissipation system 120, so as to reduce the temperature of the liquid-cooled data processing devices 130 and ensure the usability of the liquid-cooled data processing devices 130. In the liquid-cooled data processing apparatus 130, the liquid-cooled branch 134 corresponding to each data processing device 131 controls the flow rate of the cooling liquid by a branch pump 135, and can be adjusted according to the operating temperature of the data processing device 131. It can be understood that if the temperatures of the data processing devices 131 in the same liquid-cooled data processing apparatus 130 are different, the corresponding branch pumps 135 can adjust the flow rate of the cooling liquid according to the operating temperature of the corresponding data processing devices 131, so as to meet the cooling requirement of the corresponding data processing devices 131, and at the same time, the usage amount of the cooling liquid can be reduced, and the usage performance of the liquid-cooled data processing apparatus 130 can be ensured.

The invention also provides a control method of the liquid cooling data processing system 100, which is applied to the liquid cooling data processing system 100 in any embodiment; the control method comprises the following steps:

after heat exchange is performed between the cooling liquid in the temperature control heat exchange system 110 and the circulating liquid of the heat dissipation system 120, the cooling liquid after heat release enters the liquid cooling data processing device 130, absorbs heat dissipated by the liquid cooling data processing device 130, and then flows back to the temperature control heat exchange system 110;

after exchanging heat between the circulating liquid in the heat dissipation system 120 and the cooling liquid in the temperature control heat exchange system 110, the circulating liquid enters the heat dissipation unit 121 to dissipate heat, and the dissipated circulating liquid flows back to the temperature control heat exchange system 110.

One end of a liquid cooling data processing device 130 in the liquid cooling data processing system 100 is connected to the liquid supply inlet pipe 112 of the temperature control heat exchange system 110, and the other end is connected to the liquid supply return pipe 113 of the temperature control heat exchange system 110. When the liquid cooling data processing system 100 operates, the cooling liquid and the circulating liquid exchange heat in the temperature control heat exchange unit 111 of the temperature control heat exchange system 110, and the temperature control heat exchange unit 111 outputs the cooling liquid after heat release and the circulating liquid after heat absorption. The heat-released cooling liquid is transported to the liquid-cooled data processing apparatus 130 through the liquid feeding pipe 112, and cools the data processing device 131 in the liquid-cooled data processing apparatus 130, so as to absorb the heat emitted by the data processing device 131 during operation. The heat absorbed cooling liquid enters the liquid supply return pipe 113 from the liquid cooling data processing device 130, and further enters the temperature control heat exchange unit 111. The heat absorbed circulation liquid enters the heat dissipation unit 121 through the heat exchange return pipe 123, the heat of the circulation liquid is dissipated through the heat dissipation unit 121, so that the temperature of the circulation liquid is reduced, and the cooled circulation liquid enters the temperature control heat exchange unit 111 through the heat exchange inlet pipe 122. Such cycling effects cooling of the data processing device 131.

In the control method of the liquid-cooled data processing system 100 of the above embodiment, the temperature control heat exchange system 110 is used to exchange heat between the cooling liquid and the circulating liquid, and the heat-released cooling liquid is respectively delivered to the liquid-cooled data processing apparatus 130 to cool the data processing device 131 in the liquid-cooled data processing apparatus 130, thereby reducing the temperature of the data processing device 131 and ensuring the working performance of the data processing device 131, meanwhile, the liquid-cooled data processing apparatus 130 is capable of respectively delivering the cooling liquid to the data processing device 131, the module control unit of the data processing device 131 adjusts the branch pump 135 of the corresponding liquid-cooled branch 134 to realize independent control of the temperature of each data processing device 131, and further realize independent control of the working temperature of different data processing devices 131 without interfering with the operation of other data processing devices 131, so that each data processing device 131 is at a better working temperature, the usability of the data processing device 131 is guaranteed.

When the number of the liquid cooling data processing devices 130 is multiple, the cooling liquid in the temperature control heat exchange system 110 exchanges heat with the circulating liquid of the heat dissipation system 120, and the cooling liquid after heat release enters each liquid cooling data processing device 130 respectively, absorbs the heat dissipated by the liquid cooling data processing devices 130, and then flows back to the temperature control heat exchange system 110; after exchanging heat between the circulating liquid in the heat dissipation system 120 and the cooling liquid in the temperature control heat exchange system 110, the circulating liquid enters the heat dissipation unit 121 to dissipate heat, and the dissipated circulating liquid flows back to the temperature control heat exchange system 110.

Specifically, the plurality of liquid-cooled data processing devices 130 are arranged in parallel, when the liquid-cooled data processing system 100 operates, the cooling liquid and the circulating liquid exchange heat in the temperature-controlled heat exchanging unit 111 of the temperature-controlled heat exchanging system 110, and the temperature-controlled heat exchanging unit 111 outputs the cooling liquid after releasing heat and the circulating liquid after absorbing heat. The heat-released cooling liquid is respectively delivered to each liquid-cooled data processing device 130 through the liquid supply inlet pipe 112, and cools the data processing equipment 131 in the liquid-cooled data processing device 130, so as to absorb the heat emitted by the data processing equipment 131 during operation. The heat absorbed cooling liquid enters the liquid supply return pipe 113 from the liquid cooling data processing device 130 to be gathered, and then enters the temperature control heat exchange unit 111. The heat absorbed circulation liquid enters the heat dissipation unit 121 through the heat exchange return pipe 123, the heat of the circulation liquid is dissipated through the heat dissipation unit 121, so that the temperature of the circulation liquid is reduced, and the cooled circulation liquid enters the temperature control heat exchange unit 111 through the heat exchange inlet pipe 122. Such cycling effects cooling of the data processing device 131.

In an embodiment, the step of respectively entering the liquid-cooled data processing apparatuses 130 with the heat-released cooling liquid includes:

the module control unit of the data processing device 131 in each liquid-cooled data processing apparatus 130 obtains the operating temperature of each data processing device 131;

and controlling each branch pump 135 according to the working temperature and regulating the flow of the cooling liquid in each liquid cooling branch 134.

The module control unit can control the operation and shutdown of its corresponding data processing device 131, and at the same time, can acquire the operating temperature of the corresponding data processing device 131. It can be understood that the data processing device 131 is provided with a temperature sensor, and the temperature sensor can detect the working temperature of the data processing device 131 in real time and feed back the working temperature to the module control unit of the data processing device.

Moreover, after receiving the operating temperature of the data processing device 131, the module control unit can control the branch pump 135 to adjust the flow rate of the cooling liquid in the liquid cooling branch 134 according to the operating temperature, so as to meet the cooling requirement of the corresponding data processing device 131. It can be understood that, if the operating temperature of the data processing apparatus 131 is higher, the module control unit controls the opening degree of the branch pump 135 to increase, so as to increase the flow rate of the cooling liquid in the liquid cooling branch 134, thereby ensuring the cooling effect. If the working temperature of the data processing device 131 is relatively low, the module control unit controls the opening degree of the branch pump 135 to decrease, and the flow rate of the cooling liquid in the liquid cooling branch 134 is decreased, so that the usage amount of the cooling liquid can be reduced while the cooling effect is ensured.

In an embodiment, the step of respectively entering the liquid-cooled data processing apparatuses 130 with the heat-released cooling liquid further includes:

the module control unit stores a preset temperature corresponding to the working time of the data processing equipment 131;

the module control unit compares the working temperature with the preset temperature;

if the working temperature exceeds the preset temperature, controlling the opening degree of the branch pump 135 to increase;

and if the working temperature is lower than the preset temperature, controlling the opening degree of the branch pump 135 to be reduced.

It can be understood that the preset temperature of the data processing device 131 stored in the module control unit is a limit value of the operating temperature of the data processing device 131, and if the operating temperature of the data processing device 131 exceeds the limit value, the service performance of the data processing device 131 may be damaged. It is necessary to lower the operating temperature of the data processing apparatus 131 so that the operating temperature of the data processing apparatus 131 is lower than the preset temperature. If the operating temperature of the data processing device 131 exceeds the preset temperature, the module control unit controls the opening of the branch pump 135 to increase, and further increases the flow of the cooling liquid in the liquid cooling branch 134, so as to ensure the cooling effect. If the working temperature of the data processing device 131 is lower than the preset temperature, the module control unit controls the opening degree of the branch pump 135 to decrease, and the flow rate of the cooling liquid in the liquid cooling branch 134 is decreased, so that the usage amount of the cooling liquid can be decreased while the cooling effect is ensured.

In an embodiment, a module control unit stores a safety threshold for the operating temperature of the data processing device 131; the control method further comprises the following steps:

the module control unit obtains the working temperature of the corresponding data processing device 131;

and judging whether the data processing device 131 works or not according to the working temperature of the data processing device 131 and the safety threshold.

The temperature sensor in the data processing device 131 is capable of detecting the operating temperature of the data processing device 131 in real time and feeding back to the module control unit. It will be appreciated that the safety threshold refers to a limit value of a preset temperature at which the data processing device 131 normally operates. If the operating temperature of the data processing device 131 exceeds the safety threshold, the data processing device 131 is in an unsafe operating state, and needs to perform down-conversion or shutdown processing to ensure the safety performance of the data processing device 131.

In an embodiment, the determining whether the data processing device 131 operates according to the operating temperature of the data processing device 131 and the safety threshold includes the following steps:

the module control unit obtains the average temperature value of a plurality of highest temperature chips in the data processing device 131;

comparing the average value to the safety threshold;

if the average value exceeds the safety threshold, controlling the data processing equipment 131 to perform frequency reduction operation;

and if the average value still exceeds the safety threshold after the frequency reduction, controlling the data processing equipment 131 to shut down.

Each data processing device 131 in the liquid cooling data processing apparatus 130 feeds back a plurality of respective maximum chip operating temperatures to its module control unit in real time through the temperature sensor. The module control unit calculates an average value of the plurality of highest chip operation temperatures of the data processing device 131, and compares the average value with a safety threshold. If the average value is less than or equal to the safety threshold, it indicates that the data processing apparatus 131 is operating normally. If the average value is greater than the safety threshold, indicating that the data processing apparatus 131 is in the non-safety working state, the module control unit first controls the data processing apparatus 131 to perform the frequency reduction operation. If the average still exceeds the safety threshold after the frequency reduction operation, the module control unit controls the data processing device 131 to shut down, so as to ensure that the data processing device 131 can work safely.

It can be understood that if the data processing device 131 determines that the data processing device 131 is operating safely at a maximum chip temperature, there may be a misjudgment. If the data processing device 131 determines that the data processing device 131 is operating safely through excessive operating temperatures, there may be a false determination. Therefore, in the invention, the data processing device 131 judges the safe operation of the data processing device 131 through two to five working temperatures, and the service performance can be ensured.

In one embodiment, the control method further includes the steps of:

the temperature control unit acquires the actual liquid supply temperature of the cooling liquid in the liquid supply inlet pipe;

and the temperature control unit controls the heat dissipation capacity of the heat dissipation system according to the actual liquid supply temperature.

The first detection sensor 136 can detect the temperature of the cooling liquid output by the temperature-controlled heat exchange unit 111, i.e. the temperature of the cooling liquid supplied to the liquid supply pipe 112, which is the actual liquid supply temperature, and feed the actual liquid supply temperature back to the temperature-controlled control unit. The temperature control unit can control the first circulation pump 126, the control valve 124 and the cooling fan 125 to work according to the actual liquid supply temperature.

When the actual liquid supply temperature is lower, the temperature control unit controls the heat dissipation fan 125 to reduce the heat dissipation amount, controls the valve 124 and/or the first circulating pump 126 to reduce the flow rate of the circulating liquid in the circulating loop, so that the actual liquid supply temperature of the cooling liquid can be controlled at the target liquid supply temperature, the system meets the cooling requirement of the data processing equipment 131 in the most energy-saving state, and meanwhile, the liquid inlet temperature of the cooling liquid of the data processing equipment 131 is ensured to be reasonable. When the actual liquid supply temperature is higher, the temperature control unit controls the heat dissipation fan 125 to increase the heat dissipation capacity, and controls the first circulation pump 126 and/or the control valve 124 to increase the flow rate of the circulation liquid in the circulation loop, so as to ensure the cooling effect of the cooling liquid, and thus the actual liquid supply temperature of the cooling liquid is reduced to the target liquid supply temperature.

In an embodiment, the temperature control unit stores a target liquid supply temperature of the cooling liquid in the liquid supply pipe 112, and the temperature control unit controls the heat dissipation amount of the heat dissipation system according to the actual liquid supply temperature includes the following steps:

comparing the actual liquid supply temperature with the target liquid supply temperature;

and selecting a control mode according to the deviation between the actual liquid supply temperature and the target liquid supply temperature.

The target liquid supply temperature is a preset value. It is understood that the data processing device 131 may have a plurality of operation modes, and that switching the data processing device 131 between different operation modes or increasing the number of the data processing devices 131 may cause the data processing device 131 to generate temperature fluctuations. Typically, one temperature interval corresponds to a value of a target supply temperature. When the working temperature of the data processing device 131 is too high, the target liquid supply temperature needs to be decreased, so that the cooling effect of the data processing device 131 can be ensured by the low-temperature cooling liquid. When the operating temperature of the data processing device 131 is low, the target liquid supply temperature needs to be increased.

It can be understood that after the target liquid supply temperature is set, the temperature of the circulating liquid can be reduced through the cooling tower, the dry cooler, the fan and other components in the heat dissipation system 120, and then the temperature of the cooling liquid output by the temperature control heat exchange unit 111 is reduced, so as to achieve the purpose of reducing the temperature of the cooling liquid.

The module control unit obtains the working temperature of the corresponding data processing device 131 and feeds the working temperature back to the temperature control unit, and the temperature control unit can determine the target liquid supply temperature for supplying liquid to the data processing device 131. Moreover, the first detection sensor 136 can detect the temperature of the cooling liquid output by the temperature-controlled heat exchange unit 111, i.e. the temperature of the cooling liquid supplied to the liquid inlet pipe 112, which is the actual liquid supply temperature, and feed the actual liquid supply temperature back to the temperature-controlled control unit. The temperature control unit can compare the actual liquid supply temperature with the target liquid supply temperature, and then select a proper control mode, so that the cooling liquid in the liquid cooling branch 134 can effectively cool the data processing device 131, and the situations that the cooling capacity of the cooling liquid is wasted and the data processing device 131 cannot be cooled are avoided.

Specifically, when the actual liquid supply temperature is lower than the target liquid supply temperature, the temperature control unit controls the heat dissipation fan 125 to reduce the heat dissipation amount, and controls the valve 124 and/or the first circulation pump 126 to reduce the flow rate of the circulation liquid in the circulation loop, so that the actual liquid supply temperature of the cooling liquid is controlled at the target liquid supply temperature, the system meets the cooling requirement of the data processing device 131 in the most energy-saving state, and meanwhile, the liquid inlet temperature of the cooling liquid of the data processing device 131 is guaranteed to be reasonable. When the actual liquid supply temperature is higher than the target liquid supply temperature, the temperature control unit controls the heat dissipation fan 125 to increase the heat dissipation amount, and controls the first circulation pump 126 and/or the control valve 124 to increase the flow rate of the circulation liquid in the circulation loop, so as to ensure the cooling effect of the cooling liquid, and thus the actual liquid supply temperature of the cooling liquid is reduced to the target liquid supply temperature. Moreover, different control modes are selected according to the deviation between the actual liquid supply temperature and the target liquid supply temperature, so that the cooling fan 125, the first circulating pump 126 and the control valve 124 can be accurately controlled, and the actual liquid supply temperature is ensured to be close to the target liquid supply temperature quickly and accurately.

In one embodiment, the selecting a control mode based on the difference between the actual supply temperature and the target supply temperature includes:

if the deviation between the actual liquid supply temperature and the target liquid supply temperature is within a preset range, adopting an accurate mode for control;

and if the deviation between the actual liquid supply temperature and the target liquid supply temperature is out of a preset range, adopting rough mode control.

When the deviation between the actual liquid supply temperature and the target liquid supply temperature is within the preset range, it indicates that the difference between the actual liquid supply temperature and the target liquid supply temperature is relatively small, and an accurate control mode needs to be adopted to accurately adjust the cooling fan 125, the first circulating pump 126 and the control part so as to accurately reduce the actual liquid supply temperature and ensure the cooling effect of the data processing device 131. When the deviation between the actual liquid supply temperature and the target liquid supply temperature is large, a rough control mode is required, the cooling fan 125, the first circulating pump 126 and the control part are roughly controlled, the temperature of the cooling liquid is greatly changed, and then the precise control mode is adopted for control. Optionally, the predetermined range is in the range of-5 ℃ to 5 ℃. Preferably, the preset range is-2 ℃ to 2 ℃.

In an embodiment, when the precise mode control is adopted, the temperature control unit controls the adjustment step lengths of the heat dissipation fan 125, the first circulation pump 126 and the control part to be smaller than that when the coarse mode control is adopted, the temperature control unit controls the adjustment step lengths of the heat dissipation fan 125, the first circulation pump 126 and the control part. That is, when the precise mode control is adopted, the temperature control unit controls the adjustment steps of the cooling fan 125, the first circulation pump 126 and the control part to be small; when the coarse mode control is adopted, the temperature control unit controls the adjustment steps of the heat dissipation fan 125, the first circulation pump 126 and the control part to be larger.

It is understood that the step size here refers to PID [ proportional (proportional), integral (integral), and differential (differential) ] control of the heat dissipation fan 125, the first circulation pump 126, and the control part by the temperature control unit in a closed loop. The temperature control unit controls the cooling fan 125, the first circulation pump 126, and the control valve 124 in a fixed value + deviation manner. When the precise mode control is adopted, the deviation is small, and the accurate convergence of the actual liquid supply temperature is ensured. When the coarse mode control is used, the deviation becomes large to achieve a fast convergence of the actual feed liquid temperature. In the conventional control, a fixed step length, that is, a deviation is a fixed value, and the heat quantity rises quickly and is large after the data processing device 131 is started, so that the actual liquid supply temperature is converged slowly or fluctuates, and cannot be stable, and the use performance is affected. The control method of the liquid cooling data processing system 100 of the invention selects different control modes through the deviation of the actual liquid supply temperature and the target liquid supply temperature, can meet the use requirements of different working conditions, and ensures the cooling effect of the data processing equipment 131.

In an embodiment, the temperature control unit further stores a target liquid supply temperature of the cooling liquid in the liquid supply pipe 112, and the control method further includes the following steps:

comparing the actual liquid supply temperature with the target liquid supply temperature;

and if the actual liquid supply temperature is less than or equal to the target liquid supply temperature, controlling the first circulating pump 126, the cooling fan 125 and/or the control valve 124 to work according to a preset state.

And after the temperature control unit acquires the actual liquid supply temperature of the cooling liquid, comparing the actual liquid supply temperature of the cooling liquid with the target liquid supply temperature. If the actual liquid supply temperature is less than or equal to the target liquid supply temperature, it indicates that the heat dissipation capacity of the heat dissipation system 120 can meet the cooling requirement of the data processing device 131 in the liquid cooling data processing apparatus 130. Under the working state, the first circulation pump 126, the heat dissipation fan 125 and/or the control valve 124 work according to a preset state, and the heat dissipation of the circulation pump 126, the heat dissipation fan 125 and/or the control valve 124 on the circulation liquid can meet the cooling requirement of the cooling liquid in the later period. It should be noted that, in the preset operating state, there is a certain margin between the preset operating state and the full-load operating state, compared to the full-load operating state. When the actual liquid supply temperature is lower than or equal to the target liquid supply temperature, at least one of the first circulation pump 126, the cooling fan 125, and the control valve 124 is operated.

In an embodiment, the temperature control unit further stores a target liquid supply temperature and a limit liquid supply temperature of the cooling liquid in the liquid supply pipe 112, and the control method further includes the following steps:

comparing the actual liquid supply temperature, the target liquid supply temperature, and the limit liquid supply temperature;

and if the actual liquid supply temperature is greater than or equal to the target liquid supply temperature and less than or equal to the limit liquid supply temperature, controlling the first circulating pump 126, the heat dissipation fan 125 and the control valve 124 to work in a full-load state.

It will be appreciated that the threshold supply temperature is set based on the normal operating range of the data processing device 131 or the temperature demanded by the heat dissipation unit 121, such as during heating. In the prior art, when the actual liquid supply temperature exceeds the target liquid supply temperature when being too high, the system can automatically alarm, is not linked with the data processing equipment 131, and cannot adjust the actual liquid supply temperature under certain conditions, so that the use performance is influenced.

According to the control method of the liquid cooling data processing system 100, when the actual liquid supply temperature is too high, the limit liquid supply temperature is introduced, and if the actual liquid supply temperature is within the range of the target liquid supply temperature and the limit liquid supply temperature, the temperature control unit can control the cooling fan 125, the first circulating pump 126 and the control valve 124 to work in a full-load state to adjust the flow rate of the circulating liquid, so that the heat dissipation capacity is increased, and the actual liquid supply temperature of the cooling liquid is adjusted.

In one embodiment, the control method further includes the steps of:

judging whether the actual liquid supply temperature is reduced to be lower than the target liquid supply temperature or not;

if the actual liquid supply temperature is reduced to be lower than the target liquid supply temperature, controlling the first circulating pump 126, the cooling fan 125 and/or the control valve 124 to work according to a preset state;

if the actual liquid supply temperature cannot be reduced below the target liquid supply temperature:

when the working temperature of the data processing device 131 is lower than the safety threshold, controlling the first circulation pump 126, the heat dissipation fan 125 and the control valve 124 to work in a full load state;

when the working temperature of the data processing device 131 is higher than the safety threshold, the temperature control unit sends a frequency signal to the module control unit to control the data processing device 131 to reduce the frequency.

And when the actual liquid supply temperature is between the target liquid supply temperature and the limit liquid supply temperature, after the cooling fan 125, the first circulating pump 126 and the control valve 124 are controlled to be fully opened, the relation between the actual liquid supply temperature and the target liquid supply temperature is judged. And if the actual liquid supply temperature is reduced to be lower than the target liquid supply temperature, controlling the heat radiation fan 125, the first circulating pump 126 and the control valve 124 to work according to a preset state. If the temperature control unit controls the cooling fan 125, the first circulating pump 126 and the control valve 124 to be fully opened, the actual liquid supply temperature still cannot be reduced to be lower than the target liquid supply temperature, but when the module control unit detects that the working temperature of the data processing device 131 is lower than the safety threshold, it indicates that the data processing device 131 is in the range of safe operation, and at this time, the cooling of the data processing device 131 can still be ensured by the operation of the cooling fan 125, the first circulating pump 126 and the control valve 124 in a full load state, so as to ensure the safe operation of the data processing device 131.

When the temperature control unit controls the cooling fan 125, the first circulating pump 126 and the control valve 124 to be fully opened, the actual liquid supply temperature cannot be reduced to be lower than the target liquid supply temperature, but when the module control unit detects that the working temperature of the data processing device 131 is higher than the safety threshold, the data processing device 131 is in the unsafe working range, the temperature control unit sends a frequency reduction instruction to feed back the frequency reduction instruction to the module control unit, the module control unit controls the data processing device 131 to perform frequency reduction operation, the load of the data processing device 131 is reduced until the actual liquid supply temperature is reduced to be lower than the target liquid supply temperature, and therefore the data processing device 131 can work safely. It can be understood that the temperature control heat exchange unit is in transmission connection with the module control unit, so that the transmission of the frequency reduction instruction is realized, and other required signals can be transmitted.

Moreover, when the temperature control unit controls the cooling fan 125, the first circulating pump 126 and the control valve 124 to be fully opened, the actual liquid supply temperature cannot be reduced to be lower than the target liquid supply temperature, however, when the module control unit detects that the operating temperature of the data processing device 131 is above the safety threshold, it is explained that the temperature control unit has adjusted the heat dissipating capacity of the heat dissipating fan 125 to the maximum, and the first circulating pump 126 and the control valve 124 also adjust the flow rate of the circulating liquid to the maximum, in this case, the heat dissipation capability of the heat dissipation system 120 reaches a limit, such as the heat dissipation capability of the heat dissipation system 120 is insufficient or the heat dissipation capability of the heat dissipation system 120 has been increased, but the actual liquid supply temperature cannot be reduced to the target liquid supply temperature, although the data processing device 131 is not in the optimal operating temperature range, the module control unit thereof determines whether to reduce the frequency or stop the operation according to the operating temperature of the corresponding data processing device 131.

It is worth mentioning that when the actual liquid supply temperature is less than or equal to the target liquid supply temperature, the working temperature of the data processing device 131 can be ensured to be within the safe range, and the data processing device 131 can work normally and safely. When the actual liquid supply temperature rises to exceed the target liquid supply temperature and is less than or equal to the limit liquid supply temperature, the working temperature of the data processing equipment 131 cannot be controlled within a safe and reasonable range, and the working safety of the data processing equipment 131 may be affected. For this purpose, the actual supply temperature of the cooling fluid needs to be lowered, preferably by lowering the temperature of the circulating fluid through the heat dissipation fan 125, the first circulating pump 126 and/or the control valve 124, and in case the heat dissipation unit 121 cannot be realized, by controlling the operating state of the data processing device 131, i.e. down-conversion or shutdown.

If the actual liquid supply temperature is within the range of the target liquid supply temperature and the limit liquid supply temperature, the full-load operation of the cooling fan 125, the first circulating pump 126 and the control valve 124 is already controlled, but the actual liquid supply temperature cannot be reduced, it is determined whether the operating temperature of the data processing device 131 exceeds a safety threshold. If the temperature of the cooling fan 125, the first circulation pump 126 and the control valve 124 is not exceeded, the full-load working state is maintained, in this case, the working temperature of the data processing device 131 can be ensured to be within the safe range, and the liquid-cooled data processing system 100 works normally. If the frequency of the data processing equipment 131 exceeds the frequency of the frequency conversion command, the temperature control unit sends a frequency conversion command to the module control unit to control the data processing equipment 131 to perform frequency conversion operation, so that the data processing equipment 131 can work safely. That is, when the actual liquid supply temperature is higher than the target liquid supply temperature, the cooling fan 125, the first circulating pump 126 and the control valve 124 are controlled to fully operate, and if the actual liquid supply temperature is not higher than the target liquid supply temperature, whether the actual liquid supply temperature needs to be reduced is determined according to the operating temperature of the data processing device 131.

In one embodiment, the temperature control unit stores a limit supply temperature of the coolant in the liquid supply inlet pipe, and the control method further includes the steps of:

comparing the actual supply temperature of the cooling fluid in the supply inlet pipe 112 with the limit supply temperature;

if the actual liquid supply temperature of the cooling liquid in the liquid supply inlet pipe 112 exceeds the limit liquid supply temperature;

and controlling the data processing equipment 131 to work in a frequency reduction mode until the actual liquid supply temperature is reduced to be between the target liquid supply temperature and the limit liquid supply temperature.

If the tail ends of the heat dissipation unit 121 and the heat dissipation fan 125 cannot meet the heat dissipation requirement of each data processing device 131 under the condition of normal operation and heat generation, the working temperature of the data processing device 131 will inevitably rise, and the safety of the data processing device 131 in use will be affected. Therefore, no matter whether the working temperature of the data processing device 131 is within the safe range, as long as the actual liquid supply temperature exceeds the limit liquid supply temperature, the temperature control unit sends a frequency reduction instruction to the module control unit to control the data processing device 131 to perform frequency reduction operation, and reduce the load of the data processing device 131 until the actual liquid supply temperature is stable, so as to ensure that the data processing device 131 can work safely. As will be appreciated, the term "steady actual liquid supply temperature" as used herein means a decrease in actual liquid supply temperature below the threshold liquid supply temperature.

In one embodiment, the control method further includes the steps of:

acquiring the liquid level height detected by a liquid level sensor;

the temperature control heat exchange unit controls the second circulating pump 114 to adjust the flow of the cooling liquid in the liquid supply return pipe according to the liquid level height.

The temperature control unit obtains the liquid level in the second water tank 150 detected by the liquid level sensor 160, and controls the second circulation pump 114 to adjust the flow rate of the cooling liquid in the liquid return pipe according to the liquid level. When the amount of the cooling liquid in the second water tank 150 is large and the amount of the cooling liquid in the first water tank 140 is small, the liquid level sensor 160 feeds the liquid level height back to the temperature control unit, and the temperature control unit controls the second circulation pump 114 to increase the flow rate of the cooling liquid in the liquid return pipe. When the amount of the cooling liquid in the first water tank 140 is larger and the amount of the cooling liquid in the second water tank 150 is smaller, the liquid level sensor 160 feeds the liquid level height back to the temperature control unit, and the temperature control unit controls the second circulation pump 114 to reduce the flow rate of the cooling liquid in the liquid supply return pipe. Therefore, the situation that more and more cooling liquid in one water tank and less cooling liquid in the other water tank are generated can be avoided, the circulating balance of the cooling liquid in the whole system is ensured, and the working reliability of the system is ensured. The temperature control unit adopts the combination of rough control and precise control to control and sets up the constant temperature control strategy of buffer tank and has solved the slow problem of original control response, realizes the quick accurate control of coolant temperature to even guarantee that many data processing equipment 131 start simultaneously, when the heat load sharply increases, the overtemperature protection can not appear yet in data processing equipment 131.
