The invention mainly provides a tool clamp which is mainly applied to a detection device of an ice-making evaporator to position the ice-making evaporator, so that a tool is provided for realizing a new detection method, and the loss of the ice-making evaporator is reduced. The method for detecting the ice-making evaporator mainly aims to detect the welding condition of the partition sheet 2, the ice-making pipe 1 and the ice-making column 3 in the ice-making evaporator, and if the partition sheet 2 is not welded with the ice-making pipe 1 or the ice-making column 3, a gap for leaking refrigerants is reserved between the partition sheet 2 and the inner side wall of the ice-making pipe 1 or between the partition sheet 2 and the inner side wall of the ice-making column 3. When the refrigerant passes through the ice making evaporator, the refrigerant passes through the gap, so that the refrigerant does not pass through the heat exchange end 32 of the ice making column 3, and thus, the leaked refrigerant cannot transmit cold energy to the corresponding ice making column 3, so that the utilization rate of the refrigerant is reduced, and the ice making efficiency of the ice making column 3 is reduced. The detection method comprises the steps of injecting high-temperature fluid such as high-temperature gas, high-temperature water, high-temperature oil and the like into the ice making evaporator, then obtaining the temperature of the heat exchange end 32 (or other positions of the ice making column 3) of the ice making column 3 by using the temperature sensor 210 or other modes, and comparing the temperatures of the heat exchange ends 32 (or other positions of the ice making column 3) of all the ice making columns 3, wherein when the detected temperature of one ice making column 3 is lower than that of other ice making columns 3, or when the temperature of the ice making column 3 close to the fluid inlet 12 is lower than that of the ice making column 3 close to the fluid outlet 13, the welding failure of the corresponding spacing sheet 2 can be judged, and the phenomenon of refrigerant leakage can occur.

The limiting member may also be a pressing member, and the limiting member is disposed on the top of the ice making tube 1 and fixedly connected to the substrate 110, so that the limiting member applies a certain downward pressure to the ice making tube 1, and the ice making tube 1 cannot move in the mounting groove 120, so that the mounting stability of the ice making evaporator is better.

There are various arrangements of the mounting holes, with reference to the arrangement of the ice making columns 3 of the ice making evaporator. Of course, in some embodiments, in order to improve the adaptability of the tooling fixture, the number and arrangement of the mounting holes may be various, for example, the mounting holes are arranged in a matrix, so that the ice making evaporators with different shapes and models can be clamped. Of course, in some embodiments, the work fixture may simultaneously hold a plurality of ice-making evaporators in order to improve detection efficiency. It should be noted that the temperature sensor 210 may be in various forms, and may be a contact temperature sensor 210 or a non-contact temperature sensor 210, such as infrared detection.

The signal output device, the form of which may be many, specifically, comprises one or more of a display screen, a display lamp, a speaker, and a vibrator.

For example, the welding device can be a display lamp in a light form, wherein the light-on state indicates that the welding is good, and the light-off state indicates that the welding is poor; alternatively, a bright red light indicates poor welding, and a bright green light indicates good welding, and the like. Through the form of sound, can be for the speaker, the speaker directly reports temperature or testing result. The position and temperature of each ice making pipe 1 can be visually displayed on the display screen through the display form.

specifically, in the present embodiment, a high-temperature fluid is injected into the fluid inlet 12 of the ice making tube 1, and the high-temperature fluid may be high-temperature gas, water, oil, or the like, for example. The high-temperature fluid flows along the flow path of the ice-making evaporator after entering the ice-making evaporator. Firstly passes through the ice making pipe 1 and then enters the ice making column 3, and flows along a flow passage surrounded by the separation sheet 2, the ice making pipe 1 and the ice making column 3. When flowing to the heat exchanging end 32 of the ice making tube 1, the temperature of the heat exchanging end 32 of the ice making tube 1 is increased, and the temperature sensor 210 detects the temperature of the heat exchanging end 32.

Acquiring the temperature of each ice making column 3;

the temperature of each ice making column 3 may be obtained in various ways, such as by a temperature sensor 210 or by infrared means. Take the example of detection directly by the temperature sensor 210 in contact with the heat exchange end 32.

And if the temperature difference between the ice making columns 3 is smaller than the preset value, the spacer 2 and the ice making pipe 1 are well welded.

Comparing the temperatures of the ice-making columns 3 to obtain a temperature difference, wherein the temperature difference is smaller than a preset value, which indicates that the temperature change belongs to a normal range (the detection result is influenced by the detection error of the temperature sensor 210, and the approach of the temperature sensor to the fluid inlet 12 or the fluid outlet 13); if the temperature difference is larger than the preset value, it indicates that the temperature change is abnormal, and at this time, it can be determined that the high-temperature fluid does not completely flow according to the preset flow channel, but flows through other gaps 121 because other gaps 121 exist between the separation sheet 2 and the ice making tube 1 or the ice making pillars 3, and does not flow into the heat exchanging end 32, so that the temperature difference is large. The spacer 2 is connected with the ice making pipe 1 and the ice making column 3 by welding, and if other gaps 121 exist, the poor welding of the spacer 2 with the ice making column 3 or the ice making pipe 1 is explained.

Since there is heat energy dissipation in the high temperature fluid in the ice making evaporator, generally, the farther the ice making column 3 is from the fluid inlet 12, the more heat energy dissipation of the fluid flowing into the ice making column 3, and the lower the temperature of the ice making column 3, if the temperature of the ice making column 3 far from the fluid inlet 12 is higher than the temperature of the ice making column 3 near the fluid inlet 12, it should be noted that the lower temperature ice making column 3 is not welded well.

However, in other embodiments, due to the influence of the detection environment and the influence of the accuracy of the temperature sensor 210, there is a detection error, which may cause a large difference in the accuracy of the temperature detection when various factors are combined together, resulting in a temperature between the icicle 3 far from the fluid inlet 12 and the icicle 3 near to the fluid inlet 12 (two icicles 3 are adjacent) being equal to or even slightly higher than each other. At this time, it should also be judged that the welding in the icicle 3 is good.

In the above two logics, in actual use, selection should be performed according to specific working conditions, and different determination modes can be selected under different working conditions. Of course, in some embodiments, within a certain temperature difference range, the two temperature differences that are not very different can be determined as being good.

The following describes three ways of comparing the temperatures of the icicle 3, and the three ways of comparing can be operated independently, and in some embodiments, can be operated in combination to improve the reliability of the determination. It should be noted that the first icicle 3, the second icicle 3, the third icicle 3, the fourth icicle 3, and the fifth icicle 3 in the following embodiments are for clarity of description, and do not mean a specific icicle 3, and for example, the fifth icicle 3 may be any icicle 3 that meets the requirements.

First, the temperatures of two adjacent icicles 3 are compared, and the welding conditions of the spacers 2 in all the icicles 3 can be determined by comparing the temperatures of all the adjacent icicles 3:

if the temperature difference between the ice making columns 3 is smaller than the preset value, the step of determining that the partition sheet 2 and the ice making pipe 1 are well welded comprises the following steps:

determining two adjacent ice making columns 3 as a first ice making column 3 close to the fluid outlet 13 and a second ice making column 3 close to the fluid outlet 13 respectively; the first temperature difference of the first ice making column 3 higher than the second ice making column 3 is less than or equal to the first preset temperature difference, and the good welding of the spacing sheet 2 and the ice making pipe 1 is determined.

The temperature of the first ice making column 3 should be slightly higher than that of the second ice making column 3, and if the higher temperature is within a first preset temperature range, it is indicated that heat dissipation of high-temperature fluid flowing from the first ice making column 3 to the second ice making column 3 is normal, and at this time, it is determined that the welding between the separation sheet 2 in the first ice making column 3 and the second ice making column 3 and the welding between the ice making tube 1 and the ice making column 3 are good, and no gap for fluid leakage exists. The first predetermined temperature difference may be 0.5 to 2 ℃.

The method further comprises the following steps after the step of determining that the two adjacent icicles 3 are respectively a first icicle 3 close to the fluid outlet 13 and a second icicle 3 close to the fluid outlet 13: the first temperature difference of the first ice making column 3 higher than the second ice making column 3 is larger than the first preset temperature difference, and the poor welding between the spacing sheet 2 in the second ice making column 3 and the ice making pipe 1 is determined.

That is, when the temperature of the first ice making column 3 is higher than the temperature of the second ice making column 3 and exceeds the first preset temperature difference, it indicates that the high-temperature fluid does not completely pass through the heat exchanging end 32 but partially passes through the second ice making column 3 from other positions when passing through the second ice making column 3, and at this time, it indicates that the welding between the separation sheet 2 in the second ice making column 3 and the ice making tube 1 and the ice making column 3 is poor, and there is a gap affecting heat exchange.

Considering the circumstance that the environment and the influence of the temperature sensor 210 have large errors on the detected temperature, and the temperature difference between the ice making columns 3 is determined to be smaller than the preset value, the step of determining that the welding between the separation sheet 2 and the ice making pipe 1 is good comprises the following steps:

determining two adjacent ice making columns 3 as a first ice making column 3 close to the fluid outlet 13 and a second ice making column 3 close to the fluid outlet 13 respectively; and the second temperature difference of the first ice making column 3 lower than the second ice making column 3 is less than or equal to the second preset temperature difference, so that the good welding of the spacing sheet 2 and the ice making pipe 1 is determined. At this time, the temperature detection between two adjacent icicles 3 is already influenced by factors such as the environment and the detection accuracy of the temperature sensor 210, and if the temperature difference between the first icicles 3 and the second icicles 3 is in the range from zero to the second preset temperature difference, the temperature reduction amount of the high-temperature fluid passing through the first icicles 3 and the second icicles 3 is equivalent, so that the good welding between the separation sheets 2 in the third icicles 3 and the fourth icicles 3 and the ice making tubes 1 and the ice making columns 3 is determined, and no gap for leaking the fluid exists. The second predetermined temperature difference may be 0.1 to 0.3 ℃.

The method further comprises the following steps after the step of determining that the two adjacent icicles 3 are respectively a first icicle 3 close to the fluid outlet 13 and a second icicle 3 close to the fluid outlet 13: and determining that the welding between the spacing sheet 2 in the first ice making column 3 and the ice making pipe 1 is poor when the first temperature difference of the first ice making column 3 lower than the second ice making column 3 is greater than the second preset temperature difference.

When the high-temperature fluid passes through the first ice making column 3, the high-temperature fluid does not completely pass through the heat exchange end 32, but partially passes through the first ice making column 3 from other positions, and at the moment, the welding between the separation sheet 2 in the first ice making column 3 and the ice making pipe 1 and the ice making column 3 is poor, and a gap influencing heat exchange exists.

Secondly, comparing the highest and lowest temperatures of all the ice making columns 3, and after determining the current highest and lowest temperatures, selecting the ice making columns 3 with the highest and lowest temperatures from the rest ice making columns 3 for comparison so as to judge all the ice making columns 3:

if the temperature difference between the ice making columns 3 is smaller than the preset value, the step of determining that the partition plate 2 and the ice making pipe 1 are well welded comprises the following steps:

determining a third ice making column 3 with the highest temperature and a fourth ice making column 3 with the lowest temperature;

the third ice making column 3 is close to the fluid inlet 12, the fourth ice making column 3 is close to the fluid outlet 13, and the third temperature difference of the third ice making column 3 higher than the fourth ice making column 3 is less than or equal to the third preset temperature difference, so that the good welding between the spacing sheet 2 and the ice making pipe 1 is ensured; the third temperature difference of the third ice making column 3 higher than the fourth ice making column 3 is larger than the third preset temperature difference, and the poor welding between the spacing sheet 2 in the fourth ice making column and the ice making pipe 1 is determined;

it should be noted that the difference between the present embodiment and the above embodiment is that the third predetermined temperature difference between two different icicles 3 needs to be determined according to the distance difference between the two different icicles and the fluid inlet 12, and the larger the distance difference between the two different icicles and the fluid inlet 12 is, the higher the third predetermined temperature difference is; the smaller the difference between the two distances from the fluid inlet 12, the lower the third predetermined temperature difference. The minimum third preset temperature difference is the temperature difference between two adjacent ice making columns 3 and can be 0.5-2 ℃.

Considering the situation that the influence of the environment, the detection precision of the temperature sensor 210 and the like is large, the third icicle 3 is close to the fluid outlet 13, the fourth icicle is close to the fluid outlet 13, the fourth temperature difference of the third icicle 3 lower than the fourth icicle 3 is smaller than or equal to the fourth preset temperature difference, and the good welding of the spacing sheet 2 and the ice making pipe 1 is determined; and determining that the welding between the spacing sheet 2 and the ice making pipe 1 is poor due to the fact that the fourth temperature difference of the third ice making column 3 which is lower than the fourth ice making column 3 is higher than the fourth preset temperature difference.

It should be noted that the difference between the present embodiment and the above embodiment is that the fourth preset temperature difference between two different icicles 3 needs to be determined according to the distance difference between the two different icicles and the fluid inlet 12, and the larger the distance difference between the two different icicles and the fluid inlet 12 is, the higher the fourth preset temperature difference is; the smaller the difference between the two distances from the fluid inlet 12, the lower the fourth predetermined temperature difference. The minimum fourth preset temperature difference is the temperature difference between two adjacent ice making columns 3 and can be 0.1-0.3 ℃.

The temperature of all the icicles 3 is compared with a preset temperature:

the method further comprises the following steps after the step of acquiring the temperature of each ice making column 3:

comparing the temperature of each ice making column 3 with a fifth preset temperature;

and if the temperature of the fifth icicle 3 is lower than a fifth preset temperature, determining that the welding between the spacing sheet 2 in the fifth icicle 3 and the ice making pipe 1 is poor.

Specifically, in this embodiment, the fifth preset temperature may be the lowest temperature at which the high-temperature fluid normally passes through all the icicle columns 3 according to the preset flow passage and the heat exchanging end 32 in all the icicle columns 3. If the detected temperature of the heat exchange end 32 of any one ice making column 3 is lower than the fifth preset temperature, it indicates that the high-temperature fluid leaks when passing through the ice making column 3, and not all the high-temperature fluid passes through the overflowing notch 21 of the ice making column 3, which indicates that the welding between the separation sheet 2 and the ice making tube 1 or the ice making column 3 is poor.

In order to improve the accuracy and reliability of the detection, the step of injecting the high-temperature fluid into the fluid inlet 12 of the ice-making evaporator includes, before the step of:

installing an ice making evaporator on a tool clamp;

wherein, frock clamp includes: a base 100, wherein the base 100 is provided with a mounting position for mounting an ice-making evaporator; a top cover 200, on which a number of temperature sensors 210 are disposed, the temperature sensors 210 being configured to detect the temperature of the ice-making evaporator; and a signal output device electrically connected to the temperature sensor 210 and configured to output a detection result of the temperature sensor 210. Firstly, the ice making evaporator is installed in the installation groove 120 of the base 100, then the cover body is installed on the base 100 through the matching of the guide post 130 and the guide hole 220, the position of the ice making evaporator is adjusted, so that the temperature sensor 210 is arranged corresponding to the heat exchange end 32 of the ice making post 3, and then the ice making evaporator is fastened with the base 100 through the limiting piece. It is worth noting that in some embodiments, in order to further improve the detection accuracy, the temperature sensor 210 is disposed corresponding to the outer side wall of the ice making column 3 at the overflowing notch 21.

In order to further improve the accuracy of temperature detection, the step of acquiring the temperature of each ice making column 3 further comprises:

a predetermined pressure is applied to the cover body to ensure that the temperature sensor 210 is attached to the ice making column 3. The pressure is applied in various ways, and the pressure can be applied through equipment; a balancing weight can also be arranged on the top cover 200, and the balancing weight can be installed and matched with the guide column 130; it is also possible to press the top cover 200 by providing a handle 230 on the top cover 200, through the handle 230. By applying the preset pressure, the temperature sensing part 211 of the temperature sensor 210 is ensured to be attached to the heat exchange end 32 of the ice making column 3, so as to ensure the detection result.
