Description

Technical Field

[0001] The utility model relates to the technical field of server cooling, and particularly relates to an oil-immersed server cabinet. Background Art

[0002] During the operation of a mining machine server, a large amount of heat will be generated, and an effective cooling system is required to ensure its stable operation. Immersion liquid cooling is an efficient cooling method for server machines. Specifically, the mining module is directly immersed in customized liquid cooling oil, and the machine temperature is reduced through heat exchange. After the coolant absorbs heat, it is cooled by the cooling system and then circulates back to the liquid cooling tank. This method can enable the mining machine module to operate under a constant temperature condition of about 28 degrees Celsius, greatly improving the heat dissipation efficiency and optimizing the energy efficiency ratio.

[0003] Chinese Utility Model Patent CN220674232U discloses a server cabinet. A cooling cavity is provided inside the server cabinet, and the cooling cavity is filled with heat-conducting oil. The server is immersed in the heat-conducting oil. When cooling the server, oil enters from the bottom of the cooling cavity and exits from the top. The heat-conducting oil flows through the cooling cavity to take away the heat generated by the server during operation, thereby cooling the server. Although the heat dissipation effect of this server cabinet is relatively good, the direct flow of the heat-conducting oil in the server cabinet causes a large disturbance to the server host, and the server host is prone to failure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0027] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present utility model belongs.

[0028] As Figures 1-6 shown, an embodiment of the present utility model provides an oil-immersed server cabinet, which includes a box body 100 and a plurality of server hosts 200.

[0029] A lid 110 that can be opened and closed is provided at the top of the box body 100. In order to facilitate the opening and closing of the lid 110, the rear side of the lid 110 is hinged to the box body 100, and hydraulic support rods 120 hinged between the lid 110 and the box body 100 are symmetrically arranged on the left and right sides of the lid 110.

[0030] A liquid cooling tank 300 is provided inside the box body 100. The liquid cooling tank 300 is filled with heat-conducting oil, and the server host 200 is immersed in the heat-conducting oil in the liquid cooling tank 300. An inlet liquid chamber 310 and an outlet liquid chamber 320 are respectively provided on both sides of the liquid cooling tank 300. A plurality of heat exchange vertical plates 330 connected between the inlet liquid chamber 310 and the outlet liquid chamber 320 are arranged at intervals in the liquid cooling tank 300. Each server host 200 is respectively positioned between two adjacent heat exchange vertical plates 330. A coolant flow channel 331 with both ends respectively communicating with the inlet liquid chamber 310 and the outlet liquid chamber 320 is provided inside the heat exchange vertical plate 330. An inlet liquid pipe 400 extending out of the box body 100 is connected outside the inlet liquid chamber 310, and an outlet liquid pipe 500 extending out of the box body 100 is connected outside the outlet liquid chamber 320.

[0031] During use, the server host 200 is placed between the heat exchange vertical plates 330, and the server host 200 is immersed in the heat-conducting oil in the liquid cooling tank 300. The heat generated by the server host 200 is transferred to the heat-conducting oil. When dissipating heat, coolant is introduced into the inlet liquid chamber 310 through the inlet liquid pipe 400. The coolant is distributed through the inlet liquid chamber 310 into the coolant flow channels 331 inside each heat exchange vertical plate 330. During the process of the coolant flowing through the coolant flow channels 331, it exchanges heat with the heat-conducting oil in the liquid cooling tank 300 and takes away the heat, thereby cooling the server host 200. After the coolant flows through the heat exchange vertical plates 330, it enters the outlet liquid chamber 320 and is finally discharged through the outlet liquid pipe 500. Compared with the prior art, the present application not only has a better heat dissipation effect, but also during the process of dissipating heat from the server, the heat-conducting oil in the liquid cooling tank 300 does not flow, thereby reducing the disturbance to the server host 200 and reducing the failure rate of the equipment.

[0032] In this embodiment, with reference toFigure 3 and Figure 4 , on the side plate between the liquid inlet chamber 310 and the liquid cooling tank 300, a plurality of liquid inlets 340 are provided, and on the side plate between the liquid outlet chamber 320 and the liquid cooling tank 300, a plurality of liquid outlets 350 are provided. Each liquid inlet 340 corresponds to a liquid outlet 350 one by one. Flange plates 332 are provided at both ends of each heat exchange vertical plate 330. The two ends of the coolant flow channel 331 of the heat exchange vertical plate 330 are respectively butted with a corresponding group of liquid inlets 340 and liquid outlets 350. The flange plates 332 at both ends of the heat exchange vertical plate 330 are respectively fixed to the side wall of the liquid cooling tank 300 by bolts.

[0033] This embodiment further includes a plurality of plugging plates 360. The plugging plates 360 are used to plug the liquid inlets 340 and liquid outlets 350 where the heat exchange vertical plates 330 are not installed one by one. The plugging plates 360 are fixed to the side wall of the liquid cooling tank 300 by bolts.

[0034] With the above design, it is convenient to install the heat exchange vertical plates 330 in the liquid cooling tank 300. When installing the heat exchange vertical plates 330, the heat exchange vertical plates 330 can be installed at appropriate intervals according to the size of the server host 200. The liquid inlets 340 and liquid outlets 350 where the heat exchange vertical plates 330 are not installed are plugged with the plugging plates 360. In this way, the installation of server hosts 200 of different sizes can be satisfied, and the applicability is improved.

[0035] Preferably, filter nets are provided at both the liquid inlets 340 and the liquid outlets 350. In this way, the coolant entering the coolant flow channel 331 can be filtered to prevent debris from entering and causing blockage of the coolant flow channel 331.

[0036] To facilitate the fixing of bolts, a plurality of connection holes are provided around each liquid inlet 340 on the side plate between the liquid inlet chamber 310 and the liquid cooling tank 300, and around each liquid outlet 350 on the side plate between the liquid outlet chamber 320 and the liquid cooling tank 300. Nuts are welded to the side of each connection hole outside the liquid cooling tank 300.

[0037] To improve the sealing performance between both ends of the heat exchange vertical plates 330 and the plugging plates 360 and the liquid cooling tank 300, sealing gaskets are provided between the flange plates 332 at both ends of the heat exchange vertical plates 330 and the side wall of the liquid cooling tank 300, and between each plugging plate 360 and the side wall of the liquid cooling tank 300.

[0038] In this embodiment, referring to FIGS. 3 and Figure 5, inside the coolant flow channel 331, there are multiple heat conducting fins 333 arranged at intervals in the height direction, extending along the length direction and integrally formed in the heat exchange vertical plate 330. By arranging the heat conducting fins 333 in the coolant flow channel 331 of the heat exchange vertical plate 330, not only can the strength of the heat exchange vertical plate 330 be improved, but also the heat exchange efficiency between the coolant flowing through the coolant flow channel 331 and the heat exchange vertical plate 330 can be improved, thereby improving the heat dissipation efficiency of the server host 200.

[0039] This embodiment further includes a booster pump 600. The booster pump 600 is connected to the liquid inlet pipe 400. The booster pump 600 can increase the coolant pressure in the liquid inlet chamber 310, thereby ensuring that the coolant can smoothly flow into the coolant flow channels 331 of each heat exchange vertical plate 330.

[0040] Referring to Figure 3 , in order to optimize the structural layout, a support frame 700 is provided at the lower part inside the box body 100. The liquid cooling tank 300 is fixed on the support frame 700. The booster pump 600 is arranged inside the support frame 700. The liquid inlet pipe 400 is connected to the bottom of the liquid inlet chamber 310, and the liquid outlet pipe 500 is connected to the bottom of the liquid outlet chamber 320.

[0041] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
