Technical Field

The present disclosure relates to liquid-cooled heat dissipation devices, and particularly to a heat dissipation assembly for a liquid-cooled heat dissipation device.

Background

Generally, a liquid-cooled heat sink includes a liquid-cooled head, a water pump, a heat exchanger, a fan, a duct, a heat transfer liquid, and the like.

In the prior art, a heat exchanger and an axial fan are usually assembled into a heat dissipation assembly, and the assembly is then assembled and fixed on the inner side of a case wall of a system, so that the case wall must have a large enough area to accommodate the heat dissipation assembly, thereby increasing the size design requirement of the case and also limiting the application of a liquid cooling radiator in a small-sized case; especially, the existing chassis still uses air-cooled heat dissipation as the main stream, and when a compatible liquid-cooled heat dissipation structure is considered, a plurality of fixed structural components are required to be added, so that the design complexity is increased and the cost is increased.

and the heat exchanger is provided with an air inlet, the air inlet of the heat exchanger is butted with the air outlet of the centrifugal fan, and the airflow blown out from the air outlet of the centrifugal fan is blown to the air inlet of the heat exchanger.

Furthermore, the centrifugal fan comprises a plurality of fan blades, the fan blades can rotate along a rotating shaft, and air is sucked from the air inlet to generate air flow so as to be blown out from the air outlet of the centrifugal fan.

Further, the centrifugal fan is also provided with an air inlet which is used for sucking air.

Further, when the fan blades of the centrifugal fan rotate along the rotating shaft, the air inlet of the centrifugal fan sucks air in a direction parallel to the rotating shaft to generate air flow.

The following detailed description will further illustrate the invention in conjunction with the above-described figures.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention.

In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the heat dissipation assembly of the present invention will be described in further detail and described with reference to the accompanying drawings and embodiments.

Referring to fig. 1 and 2, in a preferred embodiment of the present invention, a heat dissipation assembly 10 is provided, wherein the heat dissipation assembly 10 is applied to a liquid-cooled heat dissipation device (not shown).

The liquid-cooled heat sink may further include a liquid-cooled head (not shown) and a pump (not shown). The liquid cooling head can be connected with the pump through a conduit, the pump is connected with the heat dissipation assembly through a conduit, and the heat dissipation assembly is further connected with the liquid cooling head through a conduit. Thus, the liquid cooling head, the pump and the heat dissipation assembly 10 form a heat dissipation circulation system to dissipate heat for the heating element. A thermally conductive liquid (not shown) may flow within these closed conduits.

The liquid cooling head is disposed on the heating element, can absorb heat of the heating element, and enters the heat dissipation assembly 10 for heat exchange under the action of the heat conducting liquid and the pump. After heat exchange is performed by the heat dissipation assembly 10, the cold liquid is transmitted to the liquid cooling head through a conduit to dissipate heat of the heating element 20.

In a preferred embodiment, the heat dissipation assembly 10 includes a centrifugal fan 11 and a heat exchanger 14.

The centrifugal fan 11 has an air outlet 12, and the centrifugal fan 11 is used for sucking air and blowing out from the air outlet 12.

The heat exchanger 14 has an air inlet 15, the air inlet 15 of the heat exchanger 14 is in butt joint with the air outlet 12 of the centrifugal fan 11, and the air flow blown out from the air outlet 12 of the centrifugal fan 11 is blown to the air inlet 15 of the heat exchanger 14 to dissipate heat of the heating element.

In a preferred embodiment, the centrifugal fan 11 further has an air inlet 13, and the air inlet 13 is used for sucking air. In addition, the centrifugal fan 11 is rotatable along a rotation axis a. When the centrifugal fan 11 rotates along the rotation axis a, the air inlet 13 of the centrifugal fan 11 can suck air in a direction parallel to the rotation axis a to generate an air flow. Wherein the heat exchanger 14 has a rectangular parallelepiped shape.

Further, when the centrifugal fan 11 rotates along the rotation axis a, the air outlet 12 of the centrifugal fan 11 can blow an air flow in an air flow direction perpendicular to the rotation axis a. For example, the air outlet 12 is disposed at a side of the centrifugal fan 11.

Specifically, the centrifugal fan 11 further includes a fan blade (not shown) which can rotate along the rotation axis a, and the fan blade sucks air from the air inlet 13 to generate an air flow, and finally blows the air out from the air outlet 12 of the centrifugal fan 11, and the air flow blown out from the air outlet 12 enters the inside of the heat exchanger 14.

In a preferred embodiment, the heat dissipation assembly 10 may further include a bracket 16, and the bracket 16 is used for fixedly connecting the heat exchanger 14 to a housing.

When the heating element starts to work, a certain amount of heat is generated. When the heat dissipation assembly 10 starts to operate, the air inlet 13 of the centrifugal fan 11 sucks in air to generate an air flow, and the air flow is blown out from the air outlet 12 of the centrifugal fan 11, and the air flow blown out from the air outlet 12 enters the inside of the heat exchanger 14 to dissipate heat for the heating element.

Because the air outlet 12 of the centrifugal fan 11 is arranged at the side of the centrifugal fan 11, the heat exchanger 14 and the centrifugal fans 11 with different sizes can be matched to meet the requirement of heat dissipation only by ensuring that the air outlet 12 of the centrifugal fan 11 is matched with the air inlet 15 of the heat exchanger 14.

In addition, the heat exchanger 14 has a rectangular parallelepiped shape, which is also beneficial to the layout of the internal space of the electronic device.

The heat sink assembly 10 is configured to connect an air outlet 12 of the centrifugal fan 11 with an air inlet 15 of the heat exchanger 14, and the air outlet 12 is disposed at a side of the centrifugal fan 11.

Therefore, the air flow generated by the centrifugal fan 11 can be blown out from the side, and only the air outlet 12 of the centrifugal fan 11 needs to be matched with the air inlet 15 of the heat exchanger 14, when the heat dissipation component 10 is assembled and fixed on the inner side of the wall of the system chassis, the required accommodation area of the chassis wall is small, and the adaptability of the component in the system is improved.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited. It will be understood by those skilled in the art that various modifications and equivalent arrangements can be made without departing from the spirit and scope of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
