Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for electrical equipment, specifically to a non-continuous liquid cooling system. Background Technology

[0002] Current liquid cooling solutions all involve the flow channels or pipes for heat dissipation and cooling liquid inside and outside the system equipment. Due to the requirements for preventing leakage and plugging / unplugging, the reliability of the products is greatly challenged, and the cost is also extremely high.

[0003] Furthermore, when cooling electrical equipment with heat dissipation of several kilowatts, such as power supply equipment, battery equipment, and power distribution equipment, the heat dissipation requirements are not as high as those of server equipment with heat dissipation of tens of kilowatts. Therefore, when cooling low heat dissipation electrical equipment, maintaining the stability and reliability of the electrical equipment, and reducing costs and leakage risks, is one of the research and development directions for heat dissipation components for low heat dissipation electrical equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a non-continuous liquid cooling heat dissipation system, which solves the problem.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an immersion liquid cooling design (hereinafter referred to as liquid cooling chamber) is adopted for the part of the electrical equipment that needs heat dissipation. The heat of the liquid is dissipated through a non-connected liquid cooling heat dissipation system, which includes a heat exchange component and a heat dissipation assembly. The heat exchange component and the heat dissipation assembly are respectively provided with a first heat exchange section and a second heat exchange section on opposite sides. During heat dissipation, the first heat exchange section and the second heat exchange section are in contact with each other and exchange heat. At least one set of heat pipes is provided on one side of the non-contact surface of the heat exchanger and the heat dissipation assembly along the horizontal or vertical direction, and the heat pipes adopt a high thermal conductivity structure. When in use, heat pipes are embedded inside the equipment and transfer heat from inside the equipment to the heat exchange components.

[0006] Preferably, the device is equipped with an immersion coolant, and each of the heat pipes is located below the surface of the immersion coolant.

[0007] Preferably, the heat dissipation component adopts a liquid-cooled heat absorption structure, which is fixedly installed during use without the need for plugging or unplugging. For example, when the equipment is installed on structural components such as cabinets, the heat dissipation component can be fixedly installed on the structural components such as cabinets to avoid movement during use. Furthermore, by applying the heat dissipation component to the moving parts, costs and leakage risks can be reduced. Furthermore, the heat dissipation component has a liquid cooling channel inside, with the inlet and outlet of the liquid cooling channel located on the non-contact side of the heat dissipation component and the heat exchanger.

[0008] Preferably, both the first heat exchange section and the second heat exchange section are non-planar and are in close contact with each other, thereby increasing their contact area and improving heat exchange efficiency.

[0009] Preferably, the second heat exchange section is provided with a thermally conductive material layer to enhance heat conduction efficiency.

[0010] Preferably, the heat dissipation component adopts a rear heat dissipation structure. When the power consumption of the device is not high, there is no need for liquid cooling system support. The heat is dissipated directly through the rear heat dissipation structure by external natural cooling or by using an air-cooled radiator.

[0011] Preferably, when the heat dissipation component adopts a rear heat dissipation structure, it is directly integrated with the heat exchanger.

[0012] Preferably, when the heat dissipation component and heat exchanger are designed as an integrated unit, the heat pipe and the liquid cooling chamber can be connected by inserting and fixing a closed structure.

[0013] Beneficial effects This invention provides a non-continuous liquid cooling system. Compared with existing technologies, it has the following advantages: This invention employs a non-continuous heat dissipation component inside the device to dissipate heat from low-heat-consumption electrical equipment. Furthermore, since there is no liquid connection between the heat dissipation components, the risks of plugging / unplugging and leakage can be eliminated. Furthermore, since the equipment does not require internal circulation with external liquids or air, it is easier to ensure the stability and reliability of the internal environment, thereby improving system stability. At the same time, the heat exchange effect can be improved by increasing the area of ​​the heat exchange surface and reducing the thermal resistance through material improvement, or by making a matching surface shape to increase the heat exchange area. On the other hand, heat dissipation components can be fixed to structural components such as cabinets, avoiding the use of moving parts and reducing costs and leakage risks.
