Description

Technical Field

[0001] This utility model relates to the field of cabinet heat dissipation technology, and in particular to a fluorine liquid CDU cabinet with a fluorine pump. Background Technology

[0002] The rapid development of microelectronic chip technology and the trend of miniaturization and integration of electronic components have led to a continuous increase in chip assembly density and heat flux density of components and equipment servers. If reasonable heat dissipation control technology is not adopted, it will seriously affect the performance and lifespan of electronic components.

[0003] Currently, the most efficient heat dissipation method is liquid cooling, with mainstream solutions including cold plate liquid cooling, immersion liquid cooling, and spray liquid cooling. Cold plate liquid cooling technology is a highly efficient liquid cooling method. The cold plate is a closed cavity made of high thermal conductivity metals such as copper and aluminum, which is installed on high-heat-generating components such as CPUs and GPUs. Cold plate liquid cooling mainly relies on liquid-liquid heat exchange. Most existing server racks are suitable for cooling a large number of liquid-cooled servers, and using them on a small number of liquid-cooled servers would result in energy waste.

[0004] To address the shortcomings of existing technologies, it is necessary to design a fluorine liquid CDU cabinet with a fluorine pump. Utility Model Content

The water distributor 4 is connected to the refrigerant pump CDU2 to achieve secondary side circulation. Combined with the fan 33, heat dissipation is achieved. The heat pipe backplate 3 can achieve more energy saving and reduce the size of the equipment. This cabinet can provide heat dissipation support for a small number of liquid-cooled servers in a limited space. It does not need to be laid out according to standard liquid cooling equipment, which greatly reduces the budget. Furthermore, the primary and secondary sides are integrated into one cabinet, which is highly integrated. The liquid-cooled server can be turned on and used immediately after installation without additional installation requirements.

[0023] The specific connections between the refrigerant pump CDU2, the copper tube aluminum finned heat exchanger 32, and the water distributor 4 are as follows: The refrigerant pump CDU2 includes a plate heat exchanger with two cold end interfaces and two hot end interfaces, and a refrigerant storage tank, a refrigerant pump, a dryer filter, and an electronic expansion valve connected sequentially to the cold end interface of the copper tube aluminum finned heat exchanger 32 via pipelines. The outlet of the electronic expansion valve is connected to one cold end interface of the plate heat exchanger. One hot end interface of the plate heat exchanger is connected to the hot end interface of the copper tube aluminum finned heat exchanger 32 via pipelines to form a primary side circulation, the circulating medium of which is refrigerant. It also includes a refrigerant pump connected to the copper tube aluminum finned heat exchanger 32 via pipelines. The expansion tank, degassing tank, circulating pump, and water filter are connected to the other cold end interface of the plate heat exchanger. The outlet of the water filter is connected to the cold end interface of the water distributor 4. The hot end of the water distributor 4 is connected to the other hot end interface of the plate heat exchanger through a pipe to form a secondary side circulation. A liquid replenishment module is installed on the pipe at the inlet of the circulating pump. The liquid replenishment module includes a liquid replenishment tank. Its inlet is connected to the outlet of the circulating pump through a pipe with a safety valve. Its outlet is connected in sequence to a shut-off valve, a liquid replenishment pump, a check valve, and a drying filter through a pipe. The outlet of the drying filter is connected to the pipe at the inlet of the circulating pump.

[0024] To facilitate the control and collection of parameters of the equipment on the pipeline and improve the working efficiency and safety performance of the equipment, a branch pipeline is connected between the pipeline at the outlet of the water filter and the pipeline connected to the hot end of the distributor 4. The branch pipeline is equipped with an electric two-way valve and shut-off valves respectively on both sides of the electric two-way valve. The pipeline between the copper tube aluminum fin heat exchanger 32 and the refrigerant storage tank, and the pipeline between the distributor 4 and the plate heat exchanger are equipped with shut-off valves, pressure detectors 01, and temperature transmitters 02 in sequence according to the liquid flow direction. A pressure detector 01 is installed between the refrigerant pump and the dryer filter.

[0025] The cabinet 1 houses several liquid-cooled servers. The server connection interface on the water distributor 4 is connected to the liquid-cooled servers via flexible hoses to dissipate heat from the liquid-cooled servers.

[0026] The front door of the cabinet 1 is equipped with a display screen 5 that is connected to the control system of the fluorine pump CDU2 for easy operation and observation.

[0027] The principle of heat dissipation through the connection of the refrigerant pump CDU2 with the copper tube aluminum fin heat exchanger 32 and the water distributor 4 is as follows:

[0028] The high-temperature liquid exiting from one hot end interface of the plate heat exchanger enters the hot end interface of the copper tube aluminum fin heat exchanger 32. It releases heat through the copper tube aluminum fin heat exchanger 32, becoming a low-temperature liquid. This liquid then enters the refrigerant storage tank and is pumped by the refrigerant pump to one cold end of the plate heat exchanger, forming a closed loop. The circulation pump sends the low-temperature liquid from the plate heat exchanger to the cold end interface of the distributor. The distributor 4 then sends the low-temperature liquid to the cold plates of the server's CPU and GPU, where it absorbs heat and becomes a high-temperature liquid. This liquid flows to the hot end interface of the distributor and returns to the hot end interface of the plate heat exchanger. Inside the plate heat exchanger, it exchanges heat with the liquid on the primary side of the CDU, becoming a low-temperature liquid, which then enters the circulation pump, forming a closed loop.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
