[0039] Exemplary embodiments of the present disclosure are described herein with reference to the accompanying drawings, which are meant to be exemplary in nature, and include various details intended to facilitate understanding of the present disclosure. Thus, it should be apparent to those skilled in the art that various modifications and changes can be made in the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, it should be apparent to those skilled in the art that the descriptions set forth in this specification are meant to be illustrative only and should not be taken as restrictive.

[0040] Reference will now be made to Figures 1 to 3 Embodiments of the present disclosure provide an immersion liquid cooling data center. The immersion liquid cooling data center comprises at least one subsystem, the subsystem comprising a heat exchange unit module 1, a plurality of cabinet modules 2 and a plurality of pipe box modules 3.

[0041] The cabinet module 2 comprises a box body for accommodating electronic devices such as servers, switches, power supplies, etc. The box body has a liquid inlet and a liquid outlet. The cooling liquid can flow into the box body through the liquid inlet, and the electronic devices can be immersed in the cooling liquid and exchange heat with the cooling liquid to avoid temperature exceeding the standard. The cooling liquid that absorbs the heat of the electronic devices can flow out of the box body through the liquid outlet.

[0042] The heat exchange unit module 1 is configured to provide circulating power for the cooling liquid and exchange heat of the cooling liquid to an outdoor cold source. Specifically, the heat exchange unit module 1 comprises a circulating pump and a heat exchanger. The circulating pump can provide circulating power for the cooling liquid. The heat exchanger has a primary side and a secondary side. The pipeline of the primary side is used for the cooling liquid to flow through, and the pipeline of the secondary side is used for a heat exchange working medium to flow through. The heat exchange working medium is provided by an external cold source. When the heat exchange working medium flows through the pipeline of the secondary side of the heat exchanger, it can exchange heat with the cooling liquid in the pipeline of the primary side to reduce the temperature of the cooling liquid. The heat exchanger is preferably a water-water heat exchanger.

[0043] The pipe box module 3 comprises a liquid inlet pipe 31 and a liquid return pipe 32, which are independent of each other. In order to save space, the liquid inlet pipe 31 and the liquid return pipe 32 can be arranged in parallel and spaced apart. The liquid return pipes 32 of the plurality of pipe box modules 3 are connected in sequence, and one of the liquid return pipes 32 is connected to the heat exchange unit module 1. The liquid inlet pipes 31 of the plurality of pipe box modules 3 are connected in sequence, and one of the liquid inlet pipes 31 is connected to the heat exchange unit module 1. The liquid inlet is communicated with the liquid inlet pipe 31, and the liquid outlet is communicated with the liquid return pipe 32. Specifically, the liquid return pipe 32 connected to the heat exchange unit module 1 is connected to the inlet of the pipeline of the primary side of the heat exchanger, and the liquid inlet pipe 31 connected to the heat exchange unit module 1 is connected to the output end of the circulating pump. The outlet of the pipeline of the primary side of the heat exchanger is connected to the input end of the circulating pump, and the cooling liquid can be driven by the circulating pump to flow through the plurality of cabinet modules 2 and then return to the heat exchanger.

[0044] The liquid return pipes 32 of the plurality of pipe box modules 3 in the subsystem are connected in sequence to form a liquid return main pipe, and the liquid inlet pipes 31 of the plurality of pipe box modules 3 are connected in sequence to form a liquid inlet main pipe. The liquid inlet main pipe and the liquid return main pipe have similar structures. Taking the liquid inlet main pipe as an example, the liquid inlet main pipe can be a straight-through pipe or a ring-shaped pipe. When the liquid inlet main pipe is a straight-through pipe, the two ends of the liquid inlet main pipe need to be blocked. The liquid inlet pipe 31 is connected with a liquid inlet branch pipe, which is used to connect with the liquid inlet of the tank. The liquid return pipe 32 is connected with a liquid return branch pipe, which is connected with the liquid outlet of the tank. It should be noted that, according to actual needs, the liquid return branch pipe can be connected with the liquid outlet of only one tank, or connected with the liquid outlets of multiple tanks, or blocked without being connected with the liquid outlet of the tank. Similarly, the liquid inlet branch pipe can be connected with the liquid inlet of only one tank, or connected with the liquid inlets of multiple tanks, or blocked without being connected with the liquid inlet of the tank.

[0045] In order to facilitate disassembly and assembly, the two adjacent liquid inlet pipes 31 in the liquid inlet main pipe and the two adjacent liquid return pipes 32 in the liquid return main pipe can be connected by quick clamping chucks.

[0046] In order to prevent the liquid inlet pipe 31 and the liquid return pipe 32 from being corroded, the liquid inlet pipe 31 and the liquid return pipe 32 are made of corrosion-resistant metal materials, such as stainless steel.

[0047] The submerged liquid-cooled data center provided by the present disclosure can arrange the number of subsystems according to the specific conditions of the completed site, and the number of cabinet modules 2 in the subsystem can also be arranged according to actual needs, while matching the number of pipe box modules 3. The construction is simple, easy to manage, and the quality is controllable. It is also conducive to the expansion in the later period. Compared with the traditional construction mode, it does not need to be based on the construction site to carry out deepening design, which can effectively shorten the construction period and effectively save the construction labor. It should be noted that the total heat dissipation demand of the electronic devices in each cabinet module 2 in the subsystem cannot exceed the heat dissipation capacity of the heat exchange unit module 1, wherein, Figure 1 The subsystem includes two cabinet modules 2.

[0048] Please refer to Figures 2 to 5 In an embodiment of the present disclosure, the pipe box module 3 further includes a support 33, and the liquid inlet pipe 31 and the liquid return pipe 32 are fixed to the support 33. The support 33 can support the liquid inlet pipe 31 and the liquid return pipe 32. The support 33 can be spliced by metal profiles, such as square steel.

[0049] Please refer to Figure 2In one embodiment of this disclosure, the pipe box module 3 further includes a foot pedal 35. The foot pedal 35 is laid on top of the bracket 33 and located above the inlet pipe 31 and the return pipe 32, so as to facilitate the operator to walk on the pipe box module 3, thereby facilitating the maintenance of electronic devices in the cabinet module 2.

[0050] In one embodiment of this disclosure, the pedal 35 is detachably connected to the bracket 33. Specifically, the pedal 35 can be clipped onto the bracket 33 or installed on the bracket 33 via detachable connectors such as bolts. This facilitates maintenance of the inlet pipe 31 and return pipe 32 below the pedal 35 by the operator. Of course, in other embodiments, the pedal 35 can also be welded to the bracket 33.

[0051] In one embodiment of this disclosure, the pedal 35 is made of metal, such as steel, stainless steel, or aluminum alloy. A pedal 35 made of metal provides strong support and prevents breakage. In other embodiments, the metal material can be replaced with plastic or wood.

[0052] In one embodiment of this disclosure, the pedal 35 has multiple grids, which can reduce the weight of the pedal 35 and make it easier for operators to disassemble and assemble it, and can also prevent water from accumulating on the surface of the pedal 35.

[0053] Please refer to Figure 3 and Figure 4 In one embodiment of this disclosure, the pipe box module 3 further includes a water collection tray 34, which is mounted on the bracket 33 and located below the inlet pipe 31 and the return pipe 32. By providing the water collection tray 34, condensate water condensed on the surfaces of the inlet pipe 31 and the return pipe 32 can be collected, thereby optimizing the environment. The water collection tray 34 can be made of corrosion-resistant materials such as stainless steel to enhance its corrosion resistance.

[0054] In one embodiment of this disclosure, the water collection tray 34 is U-shaped, which is simple in structure and easy to manufacture. If the arrangement direction of two adjacent pipe box modules 3 is consistent with the extension direction of the water collection tray 34, the two water collection trays 34 can be spliced ​​together by bolts, nuts or other connecting parts. It should be noted that when the two water collection trays 34 are spliced ​​together, a sealing gasket can be added between the two water collection trays 34 to prevent water leakage at the splice.

[0055] Please refer to Figure 1 , Figures 6 to 8 The immersion liquid-cooled data center also includes a frame module 4, which includes a main frame 41 and an electrical cable tray 42 disposed on the main frame 41. At least one subsystem is disposed within the main frame 41. The main frame 41 supports the electrical cable tray 42, which is used to arrange the cables of various electronic devices.

[0056] The main frame 41 can be assembled by metal profiles, and in the present disclosure, the main frame 41 is exemplarily made of square steel. The size of the main frame 41 can be determined according to the number of cabinet modules 2 in the subsystem; or the main frame 41 can be set to a standard size, but the maximum number of cabinet modules 2 contained in the subsystem accommodated in the main frame 41 will also be limited by the size of the main frame 41.

[0057] The number of subsystems accommodated in the main frame 41 can be set as needed. As shown in Figure 1 , a scheme in which two subsystems are provided in the main frame 41 is exemplarily shown, and the two subsystems are arranged in sequence along a first direction. The plurality of cabinet modules 2 in each subsystem are arranged in a row along a second direction, and the plurality of frame modules 4 in each subsystem are also arranged in a row along the second direction, the first direction and the second direction being perpendicular to each other; the two rows of pipe box modules 3 are located between the two rows of cabinet modules 2. In this way, in the two subsystems, the two rows of pipe box modules 3 are close to each other and located between the two rows of cabinet modules 2, so that the operator can walk on the two rows of pipe box modules 3 at the same time, and maintain the two rows of cabinet modules 2 at the same time, improving the maintenance efficiency. Exemplarily, the first direction can be the width direction of the main frame 41, and the second direction can be the length direction of the main frame 41.

[0058] The heat exchange unit module 1 in each subsystem can be arranged in the same row as the plurality of cabinet modules 2, specifically, the heat exchange unit module 1 can be located between any two cabinet modules 2, or at either end of the row of cabinet modules 2.

[0059] Please refer to Figure 6 , in an embodiment of the present disclosure, the main frame 41 is spaced apart in the vertical direction by a plurality of partitions 411, and each partition 411 is provided with at least one electrical bridge 42. As shown in Figure 6 , a scheme in which the main frame 41 is spaced apart in the vertical direction by two partitions 411 corresponding to each subsystem is exemplarily shown, and each partition 411 is provided with two electrical bridges 42. Among them, one of the two electrical bridges 42 of each partition 411 can be used to arrange weak current cables, and the other can be used to arrange strong current cables, which is convenient for maintenance.

[0060] Please refer to Figure 1 and Figure 8In an embodiment of the present disclosure, the immersion liquid cooling data center comprises a plurality of frame modules 4 arranged in an array, and any two adjacent frame modules 4 are detachably connected by the main frames 41. In this way, the immersion liquid cooling data center as a whole is more compact. In particular, the main frame 41 can be provided with a plurality of mounting holes, and the two main frames 41 can be connected together by bolts passing through the mounting holes and being screwed with nuts. Figure 1 and Figure 8 The number of frame modules 4 is two, and the two frame modules 4 are arranged in a row of two columns.

[0061] Please refer to Figure 9 and Figure 10 In an embodiment of the present disclosure, the immersion liquid cooling data center further comprises a hoisting module 5, which comprises a track 51 arranged on the main frame 41 and a hoisting device 52 slidingly arranged on the track 51. The track 51 is located above the cabinet module 2 and below the power bridge 42. The hoisting module 5 facilitates the hoisting of electronic devices into or out of the cabinet, and makes full use of the space between the subsystem and the power bridge 42. In particular, the hoisting device is preferably an electric hoist, and the top roller of the electric hoist can roll along the track 51, so that the electric hoist can be moved above any cabinet module 2.

[0062] In order to facilitate the hoisting of electronic devices into or out of the cabinet of the cabinet module 2, the top of the cabinet is provided with an opening, and a cover plate that can be opened and closed is arranged to open or close the opening. In this way, electronic devices can directly enter or exit the cabinet in the vertical direction.

[0063] In an embodiment of the present disclosure, the track 51 can be spliced by a plurality of track sections, and adjacent track sections can be detachably connected. In this way, the track 51 can be spliced according to the number and position of the frame modules 4. In other embodiments, the track 51 can also be provided as a whole.

[0064] In an embodiment of the present disclosure, the track 51 is in the shape of a ring. As shown in Figure 9 Since two subsystems are arranged in the frame module 4, the two rows of cabinet modules 2 are arranged in parallel and at intervals, and the ring-shaped track 51 can traverse above the two rows of cabinet modules 2. In this way, one hoisting device can meet the hoisting requirements of electronic devices in the two rows of cabinet modules 2, which can effectively reduce the cost and improve the operation and maintenance efficiency. Of course, in other embodiments, the track 51 can also be provided in a straight line, or in the shape of L, U, etc.

[0065] The above detailed description does not limit the scope of the disclosure. Various modifications, combinations, sub-combinations and alternatives can be made to the detailed description. Any modification, equivalent replacement and improvement etc. made within the spirit and principle of the disclosure shall be included in the scope of the disclosure.
