The interior of the liquid cooling cabinet 11 includes a densely arranged accommodating space 21, the accommodating space 21 is filled with cooling oil, and no computer equipment is immersed in the cooling oil. A liquid return tank 23 is provided on the side of the liquid cooling cabinet 11, and the liquid return tank 23 is connected to the liquid return pipe 13. The liquid return pipe 13 is connected to the circulating pump 14 through a manual regulating valve 27, and the flow rate of the cooling oil is manually adjusted. One end of the liquid inlet pipe 12 is connected to the flow equalizing component 24 at the bottom of the liquid cooling cabinet 11, and the other end is connected to the outlet of the heat dissipation pipe 15 in the heat dissipation unit 18. The inlet of the heat dissipation pipe 15 is connected to the circulating pump 14. The heat dissipation unit 18 cools the liquid in the heat dissipation pipe 15 by air cooling. The cooling oil flows into the accommodating space 21 from the oil outlet hole of the flow equalizing plate 25 to cool the computer equipment.

[0043] The liquid cooling cabinet 11 is installed above the cabinet bracket 22, and a flow equalizing component 24 and a flow equalizing plate 25 are installed at the bottom of the liquid cooling cabinet 11. The interior of the liquid cooling cabinet 11 is divided into a plurality of accommodating spaces 21 by a partition 26. A return tank 23 for collecting cooling oil is installed on the side of the liquid cooling cabinet 11. The cooling oil with heat is collected by utilizing the characteristic that the fluid overflow does not destroy the stratification. The notch of the return tank 23 is located at the upper part of the liquid cooling cabinet 11. The circulation pump 14 is used to drive the cooling oil to circulate between the liquid cooling cabinet 11 and the heat dissipation unit 18 to cool the computer equipment.

[0044] The first container 1 and the second container 2 are both 40HQ containers, with a length, width and height of 12.192×2.438×2.89 meters. The liquid cooling cabinet 11, the circulating liquid cooling unit and the heat dissipation unit 18 are arranged in sequence along the length direction x of the container.

[0045] A buffer (not shown) is provided between the first cavity 16 and the second cavity 17 to reduce shaking during transportation, thereby reducing wear.

[0046] The first cavity 16 is further provided with a shutter 9 and a vent 10 .

[0047] The heat dissipation unit 18 includes a heat dissipation pipe 15, a fan 19, an air inlet 4 and an air outlet 8. The installation position of the fan 19 is opposite to the air outlet 8 or the air inlet 4. The heat dissipation pipe 15 is arranged below the fan 19. The operation of the fan 19 generates negative pressure in the upper part of the second cavity 17. Air enters from the air inlet 4 below, takes away the heat of the heat dissipation pipe 15, and leaves from the air outlet 8.

[0048] In this embodiment, there are three fans 19 arranged in a row along the length direction x of the second container 2, and a guardrail 7 is installed around the fans 19.

[0050] like Figure 5 As shown, the flow equalizing component includes a flow equalizing groove 24 and a flow equalizing plate 25. The flow equalizing groove 24 and the flow equalizing plate 25 are located at the bottom of the liquid cooling cabinet 11. The flow equalizing groove 24 is connected to the liquid inlet pipe 12 to evenly distribute the cooling oil flowing in along the length direction. A plurality of oil outlet holes are evenly distributed on the flow equalizing plate 25. The positions of the holes correspond to the accommodation space 21 above, so that the cooling oil in the flow equalizing groove 24 flows evenly to the accommodation space 21 above. The upper part of the accommodation space 21 is provided with a notch of the return liquid groove 23. The cooling oil with heat flows out from the notch of the return liquid groove 23 and flows into the flow equalizing groove 24 at the bottom, and then flows into the cooled cooling oil from the oil outlet holes of the flow equalizing plate 25. The flow equalizing groove 24 and the flow equalizing plate 25 reduce the flow rate and balance the distribution of the cooling oil in the accommodation space 21, so as to achieve the purpose of stratified heat storage and enhanced heat dissipation.

[0051] In this embodiment, the first container 1 is a cabinet module, the second container 2 is a heat dissipation module, and the computer equipment is immersed in the cooling oil of the liquid cooling cabinet 11 according to a fixed position. The side of the liquid cooling cabinet 11 is provided with an oil return groove 23 and a liquid return pipe 13. The outlet of the liquid cooling cabinet 11 is connected to the heat dissipation pipe 15 of the second container 2 through a circulation pump 14, and the outlet of the heat dissipation pipe 15 is connected to the inlet of the liquid cooling cabinet 11 through a liquid inlet pipe 12. The outlet passes through the flow equalizing component 24 and the flow equalizing plate 25 in the liquid cooling cabinet 11 and enters the accommodating space 21 of the liquid cooling cabinet 11, and finally flows out from the liquid return groove 23 on the side of the liquid cooling cabinet 11, which simplifies the piping system and reduces branch pipelines.

[0052] When the computing device is immersed in cooling oil, the cooling oil enters from the bottom of the computer device and flows out from the top, taking away the internal heat of the computer device to achieve heat dissipation. Placing the computer device in cooling oil prevents the spread of noise and reduces the use of fans, achieving a noise reduction effect and achieving the perfect effect of overclocking, silent and stable operation.

[0053] A hoisting hole is arranged on the top of the container to facilitate the hoisting, maintenance and replacement of the oil pump.

[0054] The container adopts a standard 40-foot container, which has a higher degree of integration and is convenient for transportation and use.

[0055] When encountering a disaster caused by force majeure, this embodiment quickly disassembles the pipeline and separates the first container 1 and the second container 2. It has the advantages of strong mobility, convenient assembly and installation, and a short time limit for commissioning. At the same time, it has the characteristics of low cost, independent modularization, strong environmental adaptability, equal power and low energy consumption, and silent overclocking, which improves the comprehensive utilization efficiency of computer equipment and is conducive to use in various scenarios.

[0056] This embodiment is based on liquid cooling, and uses immersion liquid cooling combined with a highly maneuverable computer room cabinet to achieve rapid heat transfer and high maneuverability of the computer room, thereby improving chip utilization efficiency and safety and reducing noise caused by the cooling system.
