[0035] Referring to Figs. 1 to 3, the present embodiment provides a wind-liquid composite back door type liquid cooling cabinet 100, which includes a cabinet body 10, a back door heat dissipation device 20, a liquid cooling branching device 30, a driving device 50 (see Fig. 4), a temperature acquisition assembly, and a controller (not shown in the figures).

[0036] The cabinet body 10 comprises a rack 11 and a back door 12 provided at one side of the rack 11, the rack 11 is internally provided with a plurality of installation positions 11a (see FIG. 2), each installation position 11a is used for installing an air-cooled server 200 or a liquid-cooled server 300, and each liquid-cooled server 300 is internally provided with a liquid-cooled heat dissipation member (not shown in the figure). The back door heat dissipation device 20 is installed on the back door 12, and the back door heat dissipation device 20 comprises an air-cooled assembly 21 and a liquid-cooled assembly 22. As shown in FIG. 4, the liquid-cooled branching device 30 comprises a liquid supply main pipe 31, an adjusting component 38, a movable component 39, a liquid return main pipe 33 and a liquid return branch pipe 34 which are respectively arranged in the rack 11.

[0037] As shown in FIGS. 4 to 6, the adjusting component 38 and the movable component 39 correspond to the installation positions 11a (see FIG. 2) one by one, the adjusting component 38 is provided with a liquid supply port (not shown in the figure) and a plurality of adjusting branch pipes 381, the liquid supply port is used for communicating with the corresponding liquid-cooled heat dissipation member, one end of the adjusting branch pipe 381 communicates with the liquid supply port, and the pipe diameters of the plurality of adjusting branch pipes 381 are not equal. One end of the movable component 39 is sealingly connected with the end of the adjusting component 38 away from the liquid supply port, and can move relative to the adjusting component 38, so that the movable component 39 can selectively communicate with any one of the adjusting branch pipes 381, and the end of the movable component 39 away from the adjusting component 38 is detachably connected with the liquid supply main pipe 31. As shown in FIG. 7, the liquid return branch pipe 34 is detachably connected with the liquid return main pipe 33, the liquid return branch pipe 34 corresponds to the installation positions 11a one by one, and is used for communicating with the corresponding liquid-cooled heat dissipation member.

[0038] The driving device 50 is drivingly connected with the movable component 39, so as to drive the movable component 39 to move relative to the adjusting component 38, so that the movable component 39 can communicate with any one of the adjusting branch pipes 381. The temperature acquisition assembly is arranged in the rack 11, and is used for acquiring the temperature of the liquid-cooled server 300. The controller is electrically connected with the driving device 50 and the temperature acquisition assembly, and is used for controlling the driving device 50 to drive the movable component 39 to move according to the temperature of the liquid-cooled server 300.

[0039] The air-liquid combined back door type liquid cooling cabinet 100 is used for installing the air-cooled server 200 or the liquid-cooled server 300, so that the air-liquid combined back door type liquid cooling cabinet 100 can cope with greater power consumption by adding the liquid-cooled server 300, and further cope with the market demand of higher computing power requirements, such as 5G (5th Generation Mobile Communication Technology), AI (Artificial Intelligence), supercomputing, etc. And the liquid cooling branching device 30 is communicated with the liquid cooling heat dissipation piece in the liquid-cooled server 300, so that the cooling medium can flow through the liquid cooling heat dissipation piece through the liquid cooling branching device 30 to exchange heat, thereby improving the heat dissipation efficiency and saving the heat dissipation energy consumption. The temperature acquisition assembly is used to acquire the temperature of the liquid-cooled server 300, so as to obtain the real-time heat dissipation requirement of each liquid-cooled server 300, thereby the controller can control the driving device 50 to act according to the real-time heat dissipation requirement of the liquid-cooled server 300, so that the driving device 50 drives the movable part 39 to move relative to the adjusting part 38, so that the pipe diameter of the adjusting branch pipe 381 communicated with the movable part 39 can be adapted to the heat dissipation requirement of the liquid-cooled server 300. Specifically, since the flow of the cooling medium flowing through the adjusting part 38 is constant, the pipe diameter of the adjusting branch pipe 381 is reduced, so that the flow rate of the cooling medium in the adjusting branch pipe 381 is increased, so that the cooling medium flows into the liquid cooling heat dissipation piece through the liquid inlet at a greater flow rate, thereby enhancing the heat dissipation effect of the liquid-cooled server 300. Therefore, the controller can select the adjusting branch pipe 381 through which the cooling medium flows according to the heat dissipation requirement of different liquid-cooled servers 300, so as to realize the graded heat dissipation of different liquid-cooled servers 300, thereby further improving the heat dissipation effect and more accurately dissipating heat.

[0040] The back door heat dissipation device 20 is used for dissipating heat of the air-cooled server 200 and dissipating heat of the structure other than the heat generating device of the liquid-cooled server 300. In this way, the air-liquid combined back door type liquid cooling cabinet 100 adopts the air-cooled and liquid-cooled combined heat dissipation mode, which is more efficient and energy-saving than the pure air-cooled heat dissipation mode.

[0041] It should be noted that the air-cooled server 200 is provided with a cooling fan (not shown in the figure), and part of the heat generated by the heat generating devices in the air-cooled server 200 is discharged out of the air-cooled server 200 by the cooling fan. In the related art, the remaining heat exceeding the heat dissipation amount of the cooling fan is cooled by the air conditioning and other refrigeration forms in the machine room, and then discharged out of the air-cooled server 200, resulting in high energy consumption of the air conditioner. The air-liquid composite back door type liquid cooling cabinet 100 provided by the present application adopts liquid cooling technology, that is, the liquid cooling branching device 30 is in communication with the liquid cooling heat dissipation piece of the liquid cooling server 300, so as to directly exchange heat with the heat generating devices in the liquid cooling server 300, reduce the path cooling loss, make the refrigeration more accurate, and be beneficial to reducing the heat dissipation energy consumption and reducing the PUE (Power Usage Effectiveness, data center power utilization efficiency).

[0042] Specifically, the liquid cooling server 300 uses liquid as a cooling medium to flow in the liquid cooling heat dissipation piece, and cools the heat generating devices through heat transfer. Optionally, the liquid cooling heat dissipation piece can be a cold plate. The heat generating devices in the liquid cooling server 300 do not directly contact the liquid as the cooling medium, but dissipate heat through the cold plate assembled on the heat generating devices that need to be cooled, so as to achieve the purpose of precise refrigeration and make the operating temperature of the CPU (Central Processing Unit, central processor), GPU (graphics processing unit, graphics processor) and other heat generating devices lower.

[0043] Due to the high production, application and maintenance cost of the liquid cooling server 300, when in use, a part of the mounting positions 11a can be used to install the liquid cooling server 300, and another part of the mounting positions 11a can be used to install the air-cooled server 200, so as to meet the mixed installation requirements of the air-cooled server 200 and the liquid cooling server 300, avoid the situation of insufficient air-cooled heat dissipation, and reduce the cost. When in use, all the mounting positions 11a can be used to install the air-cooled server 200, or all the mounting positions 11a can be used to install the liquid cooling server 300, so as to be applied to the situation that the power consumption exceeds the design initial scheme, resulting in increased heat dissipation requirements.

[0044] It can be understood that when the mounting position 11a is installed with the liquid cooling server 300, the liquid supply port and the liquid return branch pipe 34 of the adjusting part 38 corresponding to the mounting position 11a are in communication with the liquid cooling heat dissipation piece of the liquid cooling server 300, so that the cooling medium enters the liquid cooling heat dissipation piece after passing through the movable part 39 and the adjusting part 38 from the liquid supply main pipe 31, exchanges heat with the heat generating devices in the liquid cooling server 300, and then flows into the liquid return main pipe 33 through the liquid return branch pipe 34. When the mounting position 11a is installed with the air-cooled server 200, the movable part 39 corresponding to the mounting position 11a is detached from the liquid supply main pipe 31, and the liquid return branch pipe 34 corresponding to the mounting position 11a is detached from the liquid return main pipe 33.

In this way, the driving device 50 is configured to drive the movable component 39 to rotate relative to the adjusting component 38, so as to switch the adjusting branch pipe 381 in communication with the movable component 39, and facilitate the arrangement of the adjusting component 38, the movable component 39 and the driving device 50 in the rack 11.

In this way, the sealing member 392 is arranged to improve the sealing between the movable component 39 and the adjusting component 38, and the liquid supply branch pipe 32 is arranged to facilitate the detachable communication with the liquid supply pipe 31.

[0047] In some embodiments, as shown in FIGS. 4 and 7, the liquid cooling branching device 30 further comprises a liquid supply connector 35 and a liquid return connector 36. The liquid supply connector 35 is arranged in one-to-one correspondence with the liquid supply branch pipe 32, and each end of the liquid supply branch pipe 32 away from the movable component 39 is detachably in communication with the liquid supply pipe 31 through the corresponding liquid supply connector 35.

The first liquid inlet and outlet chuck is arranged at one end of the liquid supply main pipe 31 (see FIG. 4) along the second direction Y and is used to communicate with the cold energy distribution unit, and the second liquid inlet and outlet chuck 37 is arranged at one end of the liquid return main pipe 33 along the second direction Y and is used to communicate with the cold energy distribution unit. In this way, the cooling medium flows into the liquid supply main pipe 31 through the first liquid inlet and outlet chuck, and the cooling medium warmed after flowing through the liquid cooling heat dissipation piece flows out of the liquid return main pipe 33 through the second liquid inlet and outlet chuck 37, so as to form a circulating flow of the cooling medium and achieve a cooling effect.

[0057] In use, the cold energy distribution unit brings the cooling medium into the liquid supply main pipe 31 through the first liquid inlet and outlet chuck, and then the cooling medium flows into the liquid cooling heat dissipation piece of the liquid cooling server 300 through the liquid supply branch pipe 32, the movable pipe 393 of the movable part 39, and one of the adjusting branch pipes 381 of the adjusting part 38, and exchanges heat with the heat generating devices in the liquid cooling server 300, such as CPU, GPU, etc., and then the warmed cooling medium flows into the liquid return main pipe 33 through the liquid return branch pipe 34, and then flows out to the cold energy distribution unit, and then exchanges heat again through the primary side and the secondary side. In this way, the cooling effect of the heat generating devices in the liquid cooling server 300 is achieved through the circulation of the cooling medium. It should be noted that the outside of the computer room is the primary side, which is composed of the water chiller and the pipe of the primary side, and the inside of the computer room is the secondary side, which is composed of the server cabinet and the pipe of the secondary side.

[0058] Specifically, the first liquid inlet and outlet chuck and the second liquid inlet and outlet chuck 37 are connected with the cold energy distribution unit through the pipe of the secondary side, respectively.

[0059] In some embodiments, as shown in FIG. 1 and FIG. 3, the back door 12 is arranged at one side of the rack 11 along the first direction X, the back door 12 includes a first door body 121 and a second door body 122, the first door body 121 and the second door body 122 are arranged in a stack along the first direction X, and along the first direction X, the second door body 122 is arranged between the rack 11 and the first door body 121. The air cooling assembly 21 is arranged in the first door body 121, and the liquid cooling assembly 22 is arranged in the second door body 122. In this way, by arranging the air cooling assembly 21 in the first door body 121, the air cooling assembly 21 can actively absorb the heat generated by the air cooling server 200 or the liquid cooling server 300 from the air-liquid composite back door type liquid cooling cabinet 100. By arranging the liquid cooling assembly 22 in the second door body 122, the hot air absorbed and exhausted from the air-liquid composite back door type liquid cooling cabinet 100 by the air cooling assembly 21 is cooled by the liquid cooling assembly 22 first, thereby reducing the temperature of the machine room.

[0060] In some embodiments, as shown in FIG. 1 to FIG. 3, the air cooling assembly 21 includes a plurality of fans 211, and the plurality of fans 211 are arranged in an array along the second direction Y and the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other. In this way, by arranging a plurality of fans 211, the heat dissipation capacity of the air cooling assembly 21 is improved. By arranging the plurality of fans 211 in an array along the second direction Y and the third direction Z, the plurality of fans 211 are more evenly arranged in the first door body 121, so as to achieve more uniform heat dissipation in the rack 11.

[0061] FIG. 10 is a sectional view of the second door body 122 in the plane perpendicular to the third direction Z in the embodiment shown in FIG. 1; and FIG. 11 is a sectional view of the second door body 122 in the plane perpendicular to the second direction Y in the embodiment shown in FIG. 1.

[0062] In some embodiments, as shown in FIG. 10 and FIG. 11, the liquid cooling assembly 22 includes an inlet liquid pipe 221, an outlet liquid pipe 222 and a heat exchange pipe 223, the inlet liquid pipe 221 and the outlet liquid pipe 222 are arranged in the second door body 122, and the heat exchange pipe 223 is in communication with the inlet liquid pipe 221 and the outlet liquid pipe 222, so that the cooling medium enters the heat exchange pipe 223 through the inlet liquid pipe 221, exchanges heat in the heat exchange pipe 223 and then flows out through the outlet liquid pipe 222.

[0063] In use, the cooling medium flowing through the liquid cooling assembly 22 can be chilled water entering the secondary side. Specifically, the water chiller pressurizes and controls the temperature of the external water source, so that the chilled water entering the secondary side flows through the inlet pipe 221 into the heat exchange pipe 223 at 5-32 degrees Celsius in the pipe of the secondary side, and then flows out through the outlet pipe 222 after flowing through the heat exchange pipe 223. In this way, by using chilled water as the cooling medium of the liquid cooling assembly 22, the liquid cooling assembly 22 has the heat dissipation capacity to handle larger power density, operates cleanly, quietly, and at lower cost and with high energy efficiency.

[0064] In some embodiments, as shown in FIGS. 10 and 11, the heat exchange pipe 223 includes a plurality of pipe sections 2231, which are in communication with each other and are arranged at intervals along the second direction Y, and each pipe section 2231 extends longitudinally along the third direction Z. The liquid cooling assembly 22 further includes a plurality of fins 23 arranged at intervals along the third direction Z, and each pipe section 2231 is respectively arranged through the plurality of fins 23 along the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In this way, by arranging the fins 23, the heat exchange area of the heat exchange pipe 223 is increased, thereby improving the heat exchange efficiency of the heat exchange pipe 223.

[0065] It should be noted that in the related art, for air-cooled machine rooms, the main refrigeration unit is an air conditioner installed in the machine room, but the reasonable power range supported by the air-cooled machine room is generally 4-6 kW. When the total power of a single cabinet exceeds 6 kW, the heat dissipation effect of air cooling is insufficient, causing the temperature of the entire machine room to rise, and thus the temperature of the air conditioner needs to be reduced or the air conditioning capacity needs to be increased, thereby increasing the energy consumption of the machine room. The present application provides the back door heat dissipation device 20 on the back door 12, so that the heat in the air-cooled server 200 or the liquid-cooled server 300 entering the front door 13 (see FIG. 1) of the air-liquid composite back door type liquid cooling cabinet 100 is discharged after passing through the back door 12 provided with the back door heat dissipation device 20, thereby achieving the cooling effect. Therefore, it is suitable for application scenarios where the total power of a single cabinet exceeds 6 kW. The front door 13 is arranged on the side of the rack 11 away from the back door 12 along the first direction X.

[0066] The air-liquid composite back door type liquid cooling cabinet 100 provided by the present application is convenient for later expansion and modification, can handle larger power density, operates cleanly and quietly, has lower cost, is energy efficient, and is suitable for mixed loading of air-cooled servers 200 and liquid-cooled servers 300.

[0067] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit it. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.
