DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] An immersion liquid cooling system includes a liquid pressure diffusion device cabin, a server heat dissipation cabin and a honeycomb heat dissipation cabin. The liquid pressure diffusion device cabin is in communication with the liquid in the server heat dissipation cabin, and the liquid in the liquid pressure diffusion device cabin and the server heat dissipation cabin realizes heat exchange through the honeycomb heat dissipation cabin.

[0035] like Figure 1 As shown, the honeycomb heat dissipation cabin is a box-type structure, the server heat dissipation cabin and the liquid pressure diffusion device cabin are both located in the box, and the liquid in the server heat dissipation cabin and the liquid pressure diffusion device cabin realizes heat exchange through the inner wall of the honeycomb heat dissipation cabin.

[0036] The server heat dissipation cabin has a built-in server 1 and an immersion liquid, namely, a coolant 2. The heat emitted by the server 1 is diffused through the coolant 2, and the coolant 2 completes heat exchange through the honeycomb heat dissipation cabin.

[0037] The server heat dissipation cabin comprises a liquid storage room, a liquid leakage partition plate 3, a liquid leakage port 4, a detection sensor 5, an electric control box 6, an isolation net 7, and a top cover door 8.

[0038] The coolant 2 is located in the liquid storage chamber, a leakage partition plate 3 is installed at the bottom of the liquid storage chamber, and a plurality of leakage ports 4 are provided on the leakage partition plate 3. The coolant 2 communicates with the liquid pressure diffusion device cabin through the plurality of leakage ports 4. A filter can be selectively placed at the leakage port 4.

[0039] The detection sensor 5 is installed in the liquid storage chamber to detect the liquid level and pressure information and transmit the signal to the control device.

[0040] The electric control box 6 is located above the immersion liquid, is used to supply power to the server 1, and is detachable and operable.

[0041] The isolation net 7 and the top cover door 8 are located on the top of the server heat dissipation cabin and are used to achieve external isolation.

[0042] The liquid pressure diffusion device cabin is used to realize pressure injection and liquid diffusion. The vertical injection pipe is plugged in according to the U position according to the position of the server 1, and the circulation flow of the immersion liquid is realized through the pressure diffusion device, thereby realizing the cooling of the CPU heat dissipation chip; the injected liquid finally returns to the liquid pressure diffusion device cabin through the server heat dissipation cabin.

[0043] like Figure 1 As shown, the liquid pressure diffusion device cabin is located at the lower part of the server heat dissipation cabin, including a pressure pump 9, a pressure main pipe 10, a pressure plug port 11, a vertical pressure plug pipe 12 and a liquid spray head.

[0044] The pressure pump 9 is connected to the pressure main pipe 10, and a plurality of pressure plug ports 11 are arranged on the pressure main pipe 10; the bottom of the vertical pressure plug pipe 12 is connected to the pressure main pipe 10 through the pressure plug port 11, and the upper part extends into the server heat dissipation cabin, and a plurality of liquid spray heads are arranged on the vertical pressure plug pipe 12.

[0045] The pressure main pipe 10 is provided with a pressure plug port 11 according to a U-mark mode.

[0046] The pressure plug port 11 is plugged in to allow fluid to pass through and pulled out to close.

[0047] The liquid spray head arranged on the vertical pressure cannula 12 is an automatic liquid spray head, which adopts a pressure-type nozzle and is opened and closed according to the pressure of the pressure pump.

[0048] The honeycomb heat dissipation cabin is provided with a honeycomb radiator 13, which exchanges heat with the liquid through the evaporator heat dissipation device, and dissipates heat through the pipeline and the external dry cooling condenser. The honeycomb radiator 13 exchanges heat with the liquid, thereby taking away the heat inside it. The honeycomb radiator 13 acts as an evaporator, is interconnected with the external heat dissipation condenser, and finally discharges the heat to the outside.

[0049] The outdoor heat exchange part can include a condensing heat exchanger, a cooling fan, etc., which are used to achieve dry self-heating cooling and utilize natural cold sources to achieve efficient heat exchange; for environments with extremely high temperatures, a compressor can be added for mechanical refrigeration.

[0050] The honeycomb heat dissipation cabin can be configured to have openings on the top side for cold liquid to enter and openings on the bottom side for liquid to flow out. Liquid cooling flows in from the top to improve heat exchange efficiency.

[0051] The immersed liquid in the server heat dissipation cabin has good cooling capacity. The heat emitted by the server can diffuse the heat of the liquid. The liquid in the box formed by the honeycomb heat dissipation cabin completes heat exchange with the inner wall of the honeycomb heat dissipation. An evaporative heat exchange cavity 14 can be formed above the immersed liquid, and heat exchange can also be completed with the inner wall of the honeycomb heat dissipation. The isolation net 7 is fixed to the top of the honeycomb heat dissipation cabin through a quick card slot 15. The honeycomb heat dissipation cabin contains a honeycomb radiator, which acts as an evaporator heat dissipation device to exchange heat with the liquid inside it, and the liquid is connected to the outdoor condenser through a pipeline.

[0052] The immersion liquid acts similarly to air, but can absorb a large amount of heat without significantly changing the temperature. Server boards and other components can be placed directly in the immersion liquid and work normally. At the same time, the liquid has a high specific heat, which enables direct and efficient heat exchange.

[0053] The injection pipe (vertical pressure insert 12) of this system uses an immersion pump (pressure pump 9) as a power source, and is effectively combined with the server through a time drive module and a temperature module to ensure the disturbance of the immersion liquid and the best heat dissipation effect. The nozzle of the injection pipe uses a pressure nozzle, which opens and closes according to the pressure of the pump. The honeycomb radiator flows with liquid inlet at the top and outlet at the bottom. The liquid cooling flows through the honeycomb heat dissipation cabin, effectively solving the problem of uniform heat exchange of the box liquid and effectively improving the heat dissipation of the liquid cooling of the immersion system.

[0054] This system fully meets the requirements of effectively solving the hot spot problem of immersed servers. Through the device of liquid injection and liquid flow outside the honeycomb heat dissipation cabin, the disturbance of the immersion liquid is achieved. At the same time, the liquid heat diffusion is achieved through the use of high-pressure spraying technology, which drives the liquid level diffusion and realizes uniform heat dissipation.

However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
