Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, and more particularly to a cooling distribution device and a data center. Background Technology

[0002] With the expansion of intelligent computing services and the iteration of artificial intelligence technology, the demand for computing power has surged, and the power density of single data center racks has continued to rise. Therefore, providing a space-efficient and easy-to-maintain cooling distribution device for data centers has become an urgent problem to solve. Summary of the Invention

[0003] This application provides a cooling distribution device and a data center, which improve the layout rationality within the cooling distribution device and enhance its maintainability.

[0004] To achieve the above objectives, this application adopts the following technical solution: A first aspect of this application provides a cooling capacity distribution device. The cabinet of the cooling capacity distribution device is used to house a heat exchanger, a first support structure, and a power supply device. The heat exchanger is used to transfer a first coolant and a second coolant for heat exchange. The first support structure is used to support and house the power supply device, which is used to supply power to electrical equipment inside the cabinet. The cabinet includes a first frame, a second frame, a third frame, and a fourth frame. The first frame and the second frame are opposite each other along a first direction, and the third frame and the fourth frame are opposite each other along a second direction. The first direction, the second direction, and the direction of gravity are perpendicular to each other. The first frame serves as a maintenance port. The gap between the heat exchanger and the first frame along the first direction is used to house the first support structure. The opening of the first support structure faces the maintenance port along the first direction. The power supply device is used to be inserted into or withdrawn from the first support structure along the first direction through the opening and the maintenance port under the action of external force.

[0005] This layout allows larger heat exchangers to be positioned at the rear of the cabinet relative to the maintenance port, while power supply units and other components are positioned at the front. For heat exchangers, this allows components that do not require frequent maintenance (compared to other components, heat exchangers have a lower maintenance frequency; in related technologies, there are cases where the cooling distribution device does not require maintenance until the heat exchanger is scrapped) to be placed in the "rear space (the part away from the maintenance port) which is more difficult to maintain" within the cabinet. This reduces the space occupied by heat exchangers in the "front space (the part near the maintenance port) which is easier to maintain" within the cabinet. For the cabinet, this frees up space near the maintenance port, making it easier to deploy components that require frequent maintenance, such as power supply units.

[0006] Furthermore, the pull-out maintenance feature of the power supply unit relative to the first support structure can alleviate the limitations and inconveniences caused by the confined space inside the cabinet for its maintenance, reducing the difficulty of the maintenance process and improving maintenance efficiency. Secondly, this "pull-out" structure can make full use of the space along the first direction of the cabinet to house the power supply unit, allowing the cabinet depth to accommodate the length of the power supply unit, reducing the space occupied by the power supply unit in the maintenance opening, and reserving more space for the installation layout of other components. For the cabinet itself, it can reduce the size of the cabinet in the second direction. In the case of parallel machines in the computer room, it can allow more cooling distribution devices to be arranged side by side along the second direction of the cabinet in a limited space, improving the centralized deployment of cooling distribution devices.

[0007] In one implementation, the cabinet is used to house the pump body, which protrudes from the heat exchanger and extends toward the first frame along a first direction. The pump body is used to obtain power from the power supply device and drive the flow of the first or second coolant. The pump body is located below the power supply device along the direction of gravity.

[0008] With this configuration, the pump body's length direction is parallel to the first direction, allowing the space within the cabinet along the first direction to accommodate the pump body's "length," thus reducing the space occupied by the pump body in the maintenance port. Furthermore, with this layout, the pump body is closer to the maintenance port, eliminating the need for operators to excessively extend into the cabinet, thereby reducing maintenance difficulty and improving maintenance efficiency.

[0009] Furthermore, the pump's placement below the power supply unit serves two purposes. First, it prevents the power supply unit from obstructing the pump along the first direction, facilitating maintenance by operators through the maintenance port. Second, it allows the power supply unit and pump to be arranged along the direction of gravity, utilizing the internal space of the cabinet along this direction to accommodate their combined size. This reduces the space occupied by the pump and power supply unit along the first or second direction, effectively minimizing the cabinet's horizontal dimensions and reducing the footprint of the cooling distribution unit. With the same deployment area, this increases the cooling distribution unit's utilization rate.

[0010] On the other hand, even if the pump body leaks liquid, the leaked liquid will fall directly downwards due to gravity and will not flow towards the power supply device. This can effectively improve the safety of the power supply device and play a certain electro-hydraulic isolation role inside the cabinet.

[0011] In one implementation, the cabinet includes a first liquid inlet, a first liquid outlet, a second liquid inlet, and a second liquid outlet. The first liquid inlet is used to receive first coolant from a refrigeration device outside the cooling capacity distribution device. The first liquid outlet is used to transfer the first coolant output from the heat exchanger to the refrigeration device. The second liquid outlet is used to output second coolant to a server outside the cooling capacity distribution device. The second liquid inlet is used to receive second coolant from the server. The distances between the first liquid inlet, first liquid outlet, second liquid inlet, and second liquid outlet and the first frame along the first direction are less than the distance between the heat exchanger and the first frame. The first liquid inlet and second liquid outlet are located between the third frame and the pump body along the second direction, and the first liquid outlet and second liquid outlet are located between the fourth frame and the pump body along the second direction. Alternatively, the first liquid inlet and second liquid outlet are located between the third frame and the power supply device along the second direction, and the first liquid outlet and second liquid outlet are located between the fourth frame and the power supply device along the second direction.

[0012] With this configuration, the first liquid inlet, the first liquid outlet, the second liquid inlet, and the second liquid outlet are closer to the maintenance port, which facilitates pipe connection between the cooling capacity distribution device and external cooling equipment and servers, and is beneficial for manual maintenance.

[0013] Furthermore, the strategic layout of the first inlet, first outlet, second inlet, and second outlet in this cooling distribution device ensures that the pipes used to transport the first and second coolants all point towards the bottom or top of the cabinet. This facilitates a unified routing of external connecting pipes, reducing the complexity of internal and external piping deployment. Secondly, this layout, with pipes running from both sides of the pump body, helps to disperse the pipes used to transport the first and second coolants within the cooling distribution device, mitigating the problem of pipes concentrating on the same side of the pump body, which can lead to crisscrossing or winding, reducing pipe length, and improving the overall rationality of the cabinet's internal layout.

[0014] In one implementation, the cabinet is used to house a first inlet pipe, a first outlet pipe, a second inlet pipe, and a second outlet pipe. The first inlet pipe, the first outlet pipe, the second inlet pipe, and the second outlet pipe extend along a third direction, which is perpendicular to the first direction and the second direction. The first inlet pipe and the first outlet pipe along the third direction are respectively opposite to the first inlet port and the first outlet port for transmitting the first coolant. The second inlet pipe and the second outlet pipe along the third direction are respectively opposite to the second inlet port and the second outlet port for transmitting the second coolant.

[0015] Since the first inlet, first outlet, second inlet, and second outlet are distributed along the second direction on both sides of the pump body or power supply device, the first inlet pipe, first outlet pipe, second inlet pipe, and second outlet pipe corresponding to the first inlet, first outlet, second inlet, and second outlet are also distributed on both sides of the pump body or power supply device. This layout can utilize the space on both sides of the pump body and power supply device for pipe routing, which not only makes reasonable use of the space inside the cabinet, but also disperses the first inlet pipe, first outlet pipe, second inlet pipe, and second outlet pipe, reducing the problem of the first inlet pipe, first outlet pipe, second inlet pipe, and second outlet pipe intersecting or winding with each other, thereby reducing the pipe length and saving costs. In addition, due to the reduction in pipe length, more space can be left inside the cabinet, reducing the density of components inside the cabinet and facilitating the deployment of other components inside the cabinet.

[0016] In one implementation, the distances between the first inlet and the first outlet and the first frame along the first direction are less than the distances between the second inlet and the second outlet and the first frame.

[0017] This configuration allows the connecting pipes between the refrigeration equipment and the cooling distribution device to run from the side where the first frame is located, while the connecting pipes between the server and the cooling distribution device run from the side where the second frame is located. In other words, it allows the connecting pipes between the cooling distribution device and the server and between the cooling distribution device and the refrigeration equipment to be separated, reducing the problems of pipe crossing or winding and lowering the difficulty of pipe deployment.

[0018] In one implementation, the heat exchanger includes a primary side inlet, a secondary side inlet, a primary side outlet, and a secondary side outlet. The primary side inlet and outlet are respectively used to connect to a first inlet pipe and a first outlet pipe to transmit a first coolant. The secondary side inlet and outlet are respectively used to connect to a second inlet pipe and a second outlet pipe to transmit a second coolant. The gap between the heat exchanger and the third frame along the second direction is used to accommodate the first inlet pipe and the second inlet pipe. The gap between the heat exchanger and the fourth frame along the second direction is used to accommodate the first outlet pipe and the second outlet pipe.

[0019] This configuration allows the heat exchanger to have only two pipes on each of its inlet and outlet sides, thus centrally arranging the four pipes corresponding to the primary inlet, secondary inlet, primary outlet, and secondary outlet in separate zones. Furthermore, since the pipes are arranged in separate zones and the pipes on the same side do not interfere with each other, the pipe design can be effectively simplified, the space occupied by the pipes can be saved, and the overall size of the unit can be reduced.

[0020] In one implementation, the heat exchanger is inclined, wherein: the primary side inlet and the secondary side outlet along the gravity direction are higher than the secondary side inlet and the primary side outlet, and one of the secondary side inlet and the primary side outlet along the gravity direction is lower than the other of the secondary side inlet and the primary side outlet; or, the secondary side inlet and the primary side outlet along the gravity direction are higher than the primary side inlet and the secondary side outlet, and one of the primary side inlet and the secondary side outlet along the gravity direction is lower than the other of the primary side inlet and the secondary side outlet.

[0021] This configuration allows for either a top-in, bottom-out flow arrangement of the first coolant and a bottom-in, top-out flow arrangement of the second coolant, or vice versa. This enables counter-current heat exchange between the first and second coolants within the heat exchanger. Counter-current heat exchange increases the logarithmic mean temperature difference between the first and second coolants, resulting in greater heat exchange capacity under the same heat exchange area and flow rate, thus improving heat exchange efficiency. Furthermore, because counter-current heat exchange allows the secondary side outlet temperature to approach the primary side inlet temperature, and the primary side outlet temperature to approach the secondary side inlet temperature, a better heat exchange depth can be achieved, meeting complex operating conditions requiring small temperature differences or high approximation.

[0022] Furthermore, this layout ensures that at least one of the primary-side inlet, secondary-side inlet, primary-side outlet, and secondary-side outlet of the heat exchanger is located at the lowest point of the entire heat exchanger. This allows gravity to be used as an active drain outlet, enabling residual liquid inside the heat exchanger to drain automatically. Compared to a parallel arrangement relative to the direction of gravity, this inclined draining method reduces the amount of residual liquid in the heat exchanger, thereby shortening the subsequent drying time, improving drying efficiency, and also helping to reduce the risk of bacterial growth due to long-term liquid accumulation.

[0023] In one implementation, the cabinet is used to house two heat exchangers, which are stacked along the direction of gravity. The first inlet pipe is used to connect the primary side inlets of the two heat exchangers, and the first outlet pipe is used to connect the primary side outlets of the two heat exchangers. The second inlet pipe is used to connect the secondary side inlets of the two heat exchangers, and the second outlet pipe is used to connect the secondary side outlets of the two heat exchangers.

[0024] The use of two heat exchangers enhances their heat exchange performance, improves the unit's expandability, and increases system compatibility. Furthermore, the stacked arrangement of the two heat exchangers makes full use of space along the direction of gravity, allowing them to fit within a minimal projected area, thus improving space utilization and reducing the cabinet's footprint. Simultaneously, the freed-up space provides greater design leeway for other structures, facilitating their size increases and providing more room for installation and removal, thereby simplifying future maintenance and replacement.

[0025] Furthermore, by branching the first inlet pipe, second inlet pipe, first outlet pipe, and second outlet pipe on one side near the two heat exchangers, a single pipe can simultaneously connect to the corresponding interfaces of both heat exchangers. This eliminates the need for additional piping length in the manifold section, thereby shortening the overall piping length and reducing the space occupied by the piping within the cabinet, resulting in a more compact and rational layout. The saved space can be used to increase the size of the heat exchangers, thereby improving heat exchange capacity and efficiency. In addition, reducing the number of pipes reduces the number of potential leakage points, thus improving the system's sealing reliability and operational safety.

[0026] In one implementation, at least one of the first liquid inlet pipe, the second liquid inlet pipe, the first liquid outlet pipe, and the second liquid outlet pipe includes a telescopic structure. The telescopic structure can contract and extend along the length of a first direction or along the length of a third direction, and the third direction is perpendicular to the first direction and the second direction.

[0027] The expandable structure provides necessary clearance when replacing heat exchangers, facilitating the connection or disconnection of pipes to corresponding heat exchanger interfaces without requiring the complete disassembly of other fixed piping. Furthermore, the expandable structure compensates for machining tolerances and assembly errors in the heat exchanger interfaces and individual pipes, preventing interference or poor sealing at connections caused by rigid connections. Additionally, the length of the expandable structure can be flexibly adjusted according to the dimensions of the heat exchanger along either the first or third direction, thus adapting to heat exchangers with different heat exchange capacities, meeting actual operating conditions, and improving product compatibility.

[0028] In one implementation, the cabinet is used to house an expansion tank, which is used to regulate the pressure of the second coolant, and the gap between the first inlet pipe or the second inlet pipe and the first frame along the first direction is used to house the expansion tank.

[0029] This ensures that the first or second inlet pipe will not obstruct the maintenance opening between the expansion tank and the first frame, facilitating the maintenance of the expansion tank.

[0030] In one implementation, the cabinet is used to accommodate a second support structure, which is fixed to the expansion tank. The second support structure is slidably connected to the top or bottom of the cabinet, or a third frame, so that the second support structure and the expansion tank can be pushed into or pulled out of the cabinet under external force.

[0031] By incorporating a second support structure within the cabinet, which allows the second support structure to move along the first direction under external force, a structural foundation is provided for supporting and guiding the movement of the expansion tank relative to the cabinet along the first direction. Secondly, the mobility of the expansion tank relative to the cabinet reduces the difficulty of the maintenance process and improves maintenance efficiency. Furthermore, compared to directly disassembling or installing the expansion tank within the cabinet, pulling the expansion tank out of the cabinet through the maintenance port and exposing it effectively avoids the risk of damage to internal components during disassembly and assembly, thus improving the safety of the internal components.

[0032] In addition, this "pull-out" structure can make full use of the space along the first direction of the cabinet to house the expansion tank, reduce the space occupied by the expansion tank for the maintenance port, and reserve more space for the installation layout of other components. For the cabinet, it can reduce the size of the cabinet in the second and third directions. When there are parallel machines in the computer room, it can enable more cooling distribution devices to be installed side by side along the second direction in a limited space, and improve the centralized deployment of cooling distribution devices.

[0033] In one implementation, the cabinet is used to house a first filter for filtering a second coolant, and the gap between the second outlet pipe and the first frame along the first direction is used to house the first filter. The first filter along the first direction includes a first maintenance window facing the maintenance port so that the filter element of the first filter can be pulled out or inserted through the first maintenance window.

[0034] This design ensures that the second outlet pipe does not obstruct the path between the first frame and the first filter, facilitating maintenance of the first filter by operators. For example, the filter element can be replaced through the maintenance port. Furthermore, this pull-out structure allows for external maintenance of the first filter, mitigating the limitations and inconveniences caused by the confined space inside the cabinet, reducing the difficulty of the maintenance process, and improving maintenance efficiency.

[0035] In one implementation, a first filter extends along a first direction, with its inlet facing a second outlet pipe along the first direction to receive the second coolant, and its outlet facing a third frame along a second direction to output the second coolant.

[0036] This configuration allows the cabinet to utilize the space along the first direction to accommodate the length of the first filter, reducing the space occupied by the maintenance port of the first filter and reserving more space for the installation layout of other components. For the cabinet, it can reduce the size of the cabinet in the second and third directions. In the case of parallel machines in the computer room, it can enable more cooling distribution devices to be installed side by side along the second direction in a limited space, improving the centralized deployment of cooling distribution devices.

[0037] Furthermore, the layout of the inlet and outlet of the first filter allows the portion of the second outlet pipe connecting to the inlet of the first filter to run along the first direction, while the other portion of the second outlet pipe connecting to the outlet of the first filter runs along the second direction. This enables these two portions of the second outlet pipe to run and extend from different sides of the first filter, improving the problems of pipe winding or crossing caused by concentrated piping, thereby reducing pipe length and lowering costs. In addition, this arrangement allows the inlet and outlet of the first filter to be located on different sides of the first filter, improving the stress problems caused by concentrated interfaces.

[0038] In one implementation, the cabinet is used to house a second filter for filtering the first coolant, and the gap between the second inlet pipe and the first frame along the first direction is used to house the second filter. The second filter includes a second maintenance window facing the top of the cabinet so that the filter element of the second filter can be pulled out or inserted through the second maintenance window.

[0039] The second filter effectively improves the purity of the first coolant, reducing wear on components such as heat exchangers, refrigeration equipment, and sensors or valves on the pipeline during the flow of the first coolant, thus extending their service life. Furthermore, the second inlet pipe does not obstruct the connection between the first frame and the second filter, facilitating maintenance of the second filter by operators, such as replacing the filter element through the maintenance port.

[0040] A second aspect of this application provides a data center comprising a server and a cooling distribution device according to any of the foregoing implementations, the cooling distribution device being used to transmit a second coolant to the server or receive a second coolant from the server to cool the server; the server being used to train an AI model or to perform inference using the AI ​​model.

[0041] As a liquid, the second coolant has a higher thermal conductivity and specific heat capacity than air. When the second coolant circulates in the system driven by the cooling distribution device, its high heat-carrying capacity effectively improves the cooling effect and efficiency of the cooling distribution device on the server. For servers, which generate a lot of heat due to training or using AI models for inference, this helps maintain the server within a suitable operating temperature range, effectively improving its stability and reliability. Furthermore, since this data center includes the cooling distribution device described in any of the aforementioned implementations, it also possesses the technical effects of the cooling distribution device described in any of the aforementioned implementations. Specific technical effects can be found above and will not be repeated here. Attached Figure Description

Detailed Implementation

[0044] Figure 1 A schematic diagram of a data center 1000 is shown. (See attached diagram) Figure 1 The data center 1000 includes a server 1100 and a cooling distribution device 1200. The cooling distribution device 1200 is used to connect the cooling equipment 1300 and the server 1100 to realize heat exchange between the cooling equipment 1300 and the server 1100.

[0045] Figure 2 A schematic diagram of the internal piping connection of a cooling capacity distribution device 1200 is shown. (See attached diagram) Figure 2The cooling capacity distribution device 1200 includes a heat exchanger 210, which includes a primary-side liquid inlet 211, a primary-side liquid outlet 213, a secondary-side liquid inlet 212, and a secondary-side liquid outlet 214. The primary-side liquid inlet 211 receives a first coolant from the refrigeration equipment 1300, and the primary-side liquid outlet 213 supplies the first coolant to the refrigeration equipment 1300. The secondary-side liquid inlet 212 receives a second coolant from the server 1100, and the secondary-side liquid outlet 214 supplies the second coolant to the server 1100.

[0046] See also Figure 2 The cooling capacity distribution device 1200 includes a primary side pipe 510 and a secondary side pipe 520. The primary side pipe 510 is connected to the primary side inlet 211 and the primary side outlet 213 for transmitting the first coolant, and the secondary side pipe 520 is connected to the secondary side inlet 212 and the secondary side outlet 214 for transmitting the second coolant.

[0047] See also Figure 2 The cooling capacity distribution device 1200 includes a power supply device 220, which is used to supply power to the electrical equipment in the cooling capacity distribution device 1200.

[0048] See also Figure 2 The cooling capacity distribution device 1200 includes a pump body 240, which is connected between the server 1100 and the heat exchanger 210. The pump body 240 obtains electrical energy from the power supply device 220 and is used to drive the flow of the second coolant in the secondary side pipeline 520. Alternatively, the pump body 240 is connected between the refrigeration equipment 1300 and the heat exchanger 210 and is used to drive the flow of the first coolant in the primary side pipeline 510.

[0049] See also Figure 2 The cooling capacity distribution device 1200 includes an expansion tank 250, which is connected between the server 1100 and the heat exchanger 210. The expansion tank 250 is used to regulate the pressure of the second coolant.

[0050] See also Figure 2 The cooling distribution device 1200 includes a first filter 610, which is connected between the server 1100 and the heat exchanger 210. The first filter 610 is used to filter the second coolant to improve the purity of the second coolant.

[0051] See also Figure 2 The cooling capacity distribution device 1200 includes a second filter 620, which is connected between the refrigeration equipment 1300 and the heat exchanger 210. The second filter 620 is used to filter the first coolant to improve the purity of the first coolant.

[0052] Below, this application will combine Figures 3-12 This paper describes the relative positions and connections of components such as heat exchanger 210, power supply device 220, pump body 240, expansion tank 250, first filter 610 and second filter 620 in the cold energy distribution device 1200.

[0053] first, Figure 3 A schematic diagram of a cabinet 100 for a cooling capacity distribution device 1200 is shown. The cabinet 100 houses components such as the heat exchanger 210, power supply device 220, pump 240, expansion tank 250, first filter 610, and second filter 620. See also Figure 3 The cabinet 100 includes a first frame 110, a second frame 120, a third frame 130, and a fourth frame 140. The first frame 110 and the second frame 120 are arranged opposite each other along a first direction X, and the third frame 130 and the fourth frame 140 are arranged opposite each other along a second direction Y. The first direction X, the second direction Y, and the direction of gravity are perpendicular to each other. The first frame 110, the second frame 120, the third frame 130, and the fourth frame 140 enclose a receiving space. The first frame 110 serves as a maintenance port 111 for the cold air distribution device 1200. That is, the first frame 110 is open, allowing maintenance personnel to maintain the components inside the cabinet 100 through the first frame 110. Of course, in practical applications, the cabinet 100 can also be equipped with a maintenance door, which is movably connected to the first frame 110 to open or close the first frame 110. In addition, the second frame 120, the third frame 130, and the fourth frame 140 can be open or solid plate structures in practical applications.

[0054] Figure 4 A schematic diagram of a cooling capacity distribution device 1200 is shown from one perspective. See [link / reference] Figure 4 The cabinet 100 is also used to accommodate the first support structure 310. The gap between the heat exchanger 210 and the first frame 110 along the first direction X is used to accommodate the first support structure 310. The opening of the first support structure 310 faces the maintenance port 111. The first support structure 310 is used to house and support the power supply device 220. The power supply device 220 can be pulled out or inserted into the first support structure 310 along the first direction X through the opening and maintenance port 111 under the action of external force, so as to facilitate installation and disassembly. For example, a guide rail is provided in the first support structure 310, which extends along the first direction X, and the power supply device 220 can move along the guide rail.

[0055] With this configuration, the power supply device 220 can be pulled out of the maintenance port 111 for maintenance by pulling it out along the first direction X. This makes it convenient for maintenance personnel to maintain the device and avoids them having to enter the cabinet 100 for maintenance. On the other hand, it can also greatly reduce the maintenance space that needs to be reserved for the power supply device 220, thereby optimizing the space utilization of the cooling distribution device 1200.

[0056] Compared to double-sided maintenance, this single-sided maintenance layout restricts operators to maintaining the components inside the cabinet 100 only from one side. Specifically, the side containing the first frame 110 is the maintenance side of the cabinet 100, while the sides containing the second frame 120, third frame 130, and fourth frame 140 are the non-maintenance sides. With this architecture, during the deployment of the cooling distribution device 1200, the side containing the second frame 120, opposite the maintenance port 111, can be directly attached to the wall. Figure 1 The wall (represented by the dashed line W) is designed so that a maintenance passage only needs to be reserved on the side where the maintenance port 111 is located, reducing the space occupied by the maintenance passage and saving the floor space of the cooling distribution unit 1200 in the equipment room. This allows adjacent cabinets 100 to be installed close together, thereby increasing the cabinet utilization rate. On this basis, the number of cooling distribution units 1200 deployed can be effectively increased, thus supporting more servers 1100 and improving the power density of the data center 1000. In addition, for cabinet 100, all components are maintained from the side where the maintenance port 111 is located, i.e., front maintenance, with ample maintenance space and convenient operation, which can effectively reduce the mean time to repair and improve the availability of the cooling distribution unit 1200.

[0057] Referring again to 4, in one embodiment of this application, the pump body 240 protrudes from the heat exchanger 210 and extends toward the first frame 110 along the first direction X. This arrangement allows the space within the cabinet 100 along the first direction X to accommodate the "length" of the pump body 240, thereby reducing the area occupied by the pump body 240 relative to the maintenance port 111. In addition, the pump body 240 is close to the maintenance port 111, which means that the operator does not need to extend excessively into the cabinet 100, making it easier to perform maintenance operations on the pump body 240 and improving maintenance efficiency.

[0058] In addition, in this embodiment, the pump body 240 is located below the power supply device 220 along the direction of gravity. This arrangement allows the power supply device 220 and the pump body 240 to be arranged along the direction of gravity, utilizing the space inside the cabinet 100 along the third direction Z to accommodate the superimposed size of the power supply device 220 and the pump body 240, reducing the size of the cabinet 100 along the horizontal plane. Under the same deployment area, the cabinet output rate of the cooling distribution device 1200 can be improved. Furthermore, even if the pump body 240 leaks liquid, the leaked liquid will fall directly downwards due to gravity and will not flow towards the power supply device 220. This can effectively improve the safety of the power supply device 220 and provide a certain electro-hydraulic isolation effect within the cabinet 100.

[0059] In one embodiment of this application, the cooling capacity distribution device 1200 further includes a first pipe 410 and a second pipe 420. Figure 5 A schematic diagram of a pump body 240, a first pipe 410, and a second pipe 420 is shown. See [link / reference] Figure 5 The inlet of the pump body 240 is connected to the secondary side pipeline 520 via a first pipe 410, and the outlet of the pump body 240 is connected to the secondary side pipeline 520 via a second pipe 420. Furthermore, both the first pipe 410 and the second pipe 420 include a first section 430 and a second section 440 extending along a third direction Z. The first section 430 and the second section 440 are detachably connected. When the first section 430 and the second section 440 are detached, the pump body 240 is used to move along the first direction X under the action of an external force.

[0060] This design, with its mobility relative to the cabinet 100, effectively mitigates the limitations and inconveniences caused by the confined space within the cabinet, reducing the difficulty of maintenance and improving efficiency. Furthermore, the detachable connection between the first section 430 and the second section 440 provides a basis for the pump body 240 to move along the first direction X, ensuring that the secondary side piping 520 connected to the pump body 240 does not interfere with its movement, thus facilitating pull-out maintenance of the pump body 240.

[0061] In one embodiment of this application, the cabinet 100 further includes a first liquid inlet 710, a first liquid outlet 720, a second liquid inlet 730, and a second liquid outlet 740. Figure 6 A schematic diagram of a first liquid inlet 710, a first liquid outlet 720, a second liquid inlet 730, and a second liquid outlet 740 is shown. (See attached diagram.) Figure 6The first liquid inlet 710 is used to receive the first coolant from the refrigeration equipment 1300 outside the cooling capacity distribution device 1200, and the first liquid outlet 720 is used to transfer the first coolant output from the heat exchanger 210 to the refrigeration equipment 1300. For example, the primary side pipeline 510 is connected to the connecting pipeline between the cooling capacity distribution device 1200 and the refrigeration equipment 1300 through the first liquid inlet 710 and the first liquid outlet 720.

[0062] The second outlet 740 is used to output the second coolant to the server 1100 outside the cooling capacity distribution device 1200, and the second inlet 730 is used to receive the second coolant from the server 1100. For example, the secondary side pipeline 520 is connected to the connecting pipeline between the cooling capacity distribution device 1200 and the server 1100 through the second outlet 740 and the second inlet 730.

[0063] This setup allows different inlet and outlet liquid pipes to enter and exit independently relative to the cabinet 100, reducing mutual interference between different inlet and outlet liquid pipes and simplifying pipe deployment.

[0064] In addition, see also Figure 6 In this embodiment of the application, the distances between the first liquid inlet 710, the first liquid outlet 720, the second liquid inlet 730, and the second liquid outlet 740 along the first direction X and the first frame 110 are less than the distance between the heat exchanger 210 and the first frame 110. This arrangement allows the first liquid inlet 710, the first liquid outlet 720, the second liquid inlet 730, and the second liquid outlet 740 along the first direction X to be closer to the maintenance port 111, which facilitates the pipe connection between the cold energy distribution device 1200 and the external refrigeration equipment 1300 and the server 1100, and is beneficial for manual maintenance.

[0065] See also Figure 6 In this embodiment of the application, the first liquid inlet 710 and the second liquid inlet 730 along the second direction Y are located between the third frame 130 and the pump body 240, and the first liquid outlet 720 and the second liquid outlet 740 along the second direction Y are located between the fourth frame 140 and the pump body 240. This arrangement allows the outlet directions of the primary side pipe 510 and the secondary side pipe 520 to face the bottom of the cabinet 100, which facilitates the connection pipes between the cold energy distribution device 1200 and the refrigeration equipment 1300 and the server 1100 to run from under the floor.

[0066] In another embodiment of this application, the first liquid inlet 710 and the second liquid inlet 730 along the second direction Y are located between the third frame 130 and the power supply device 220, and the first liquid outlet 720 and the second liquid outlet 740 along the second direction Y are located between the fourth frame 140 and the power supply device 220. This arrangement allows the outlet directions of the primary side pipe 510 and the secondary side pipe 520 to face the top of the cabinet 100, which facilitates the cooling capacity distribution device 1200, the refrigeration equipment 1300, and the server 1100 to run pipes from the top of the cabinet 100.

[0067] Furthermore, the unified piping direction under both layouts not only facilitates the internal piping layout of the cooling distribution device 1200, but also enables the unified deployment of connecting pipes between the cooling distribution device 1200, the server 1100, and the refrigeration equipment 1300. Secondly, this piping layout from both sides of the pump body 240 helps to disperse the primary side piping 510 and the secondary side piping 520, improving the problems of pipe crossing or winding caused by concentrating pipes on the same side of the pump body 240, reducing pipe length, and improving the rationality of the internal layout of the cabinet 100.

[0068] In one embodiment of this application, see also: Figure 2 , Figure 4 and Figure 6 The primary side pipeline 510 includes a first inlet pipe 511 and a first outlet pipe 512, and the secondary side pipeline 520 includes a second inlet pipe 521 and a second outlet pipe 522. The first inlet pipe 511, the first outlet pipe 512, the second inlet pipe 521 and the second outlet pipe 522 all extend along the third direction Z. The first inlet pipe 511 along the third direction Z is arranged opposite to the first inlet port 710 to receive the first coolant, and the first outlet pipe 512 along the third direction Z is arranged opposite to the first outlet port 720 to output the first coolant. For example, a part of the first inlet pipe 511 extends out of the cabinet 100 through the first inlet port 710 and is connected to the connecting pipe between the cooling capacity distribution device 1200 and the refrigeration equipment 1300, and a part of the first outlet pipe 512 extends out of the cabinet 100 through the first outlet port 720 and is connected to the connecting pipe between the cooling capacity distribution device 1200 and the refrigeration equipment 1300.

[0069] A second inlet pipe 521 is disposed opposite to a second inlet port 730 along the third direction Z to receive the second coolant, and a second outlet pipe 522 is disposed opposite to a second outlet port 740 along the third direction Z to output the second coolant. For example, a portion of the second inlet pipe 521 extends out of the cabinet 100 through the second inlet port 730 and is connected to the connecting pipe between the cooling capacity distribution device 1200 and the server 1100, and a portion of the second outlet pipe 522 extends out of the cabinet 100 through the second outlet port 740 and is connected to the connecting pipe between the cooling capacity distribution device 1200 and the server 1100.

[0070] With this configuration, since the first inlet 710, the first outlet 720, the second inlet 730, and the second outlet 740 are distributed along the second direction Y on both sides of the pump body 240 or the power supply device 220, the first inlet pipe 511, the first outlet pipe 512, the second inlet pipe 521, and the second outlet pipe 522 are also distributed on both sides of the pump body 240 or the power supply device 220. This layout can utilize the space on both sides of the pump body 240 and the power supply device 220 for pipe routing, and can disperse the first inlet pipe 511, the first outlet pipe 512, the second inlet pipe 521, and the second outlet pipe 522, reducing the problem of the first inlet pipe 511, the first outlet pipe 512, the second inlet pipe 521, and the second outlet pipe 522 intersecting or winding, shortening the pipe length, freeing up more space inside the cabinet 100, reducing the density of components inside the cabinet 100, and facilitating the deployment of other components inside the cabinet 100.

[0071] See also Figure 6 In one embodiment of this application, the distance between the first liquid inlet 710 and the first liquid outlet 720 and the first frame 110 along the first direction X is less than the distance between the second liquid inlet 730 and the second liquid outlet 740 and the first frame 110. This arrangement facilitates the connection pipe between the refrigeration equipment 1300 and the cold energy distribution device 1200 to run from the side where the first frame 110 is located, and the connection pipe between the server 1100 and the cold energy distribution device 1200 to run from the side where the second frame 120 is located. This can separate the connection pipes between the cold energy distribution device 1200 and the server 1100 and the refrigeration equipment 1300, reduce the problem of pipe crossing or winding, and reduce the difficulty of deploying the connection pipes.

[0072] In one embodiment of this application, Figure 7 A schematic diagram of a cooling capacity distribution device 1200 is shown. (See attached diagram.) Figure 4 and Figure 7 The first liquid inlet pipe 511 and the second liquid inlet pipe 521 are located in the gap between the heat exchanger 210 and the third frame 130 along the second direction Y, and the first liquid outlet pipe 512 and the second liquid outlet pipe 522 are located in the gap between the heat exchanger 210 and the fourth frame 140 along the second direction Y.

[0073] This arrangement allows the four pipes corresponding to each heat exchanger 210 to be arranged in a centralized manner, and the pipes on the same side do not interfere with each other, which simplifies the pipe design, saves the space occupied by the pipes, and thus reduces the overall size of the unit.

[0074] See also Figure 7In some examples of embodiments of this application, the primary side inlet 211 is located above the secondary side inlet 212, and the primary side outlet 213 is located below the secondary side outlet 214. This arrangement creates a flow pattern where the first coolant enters from the top and exits from the bottom, and the second coolant enters from the bottom and exits from the top, allowing the first and second coolants to exchange heat in a counter-current manner within the heat exchanger 210. In counter-current mode, the logarithmic mean temperature difference between the first and second coolants is maximized, thereby achieving higher heat exchange capacity under the same heat exchange area and flow rate, thus improving heat exchange efficiency.

[0075] Furthermore, since the counter-current arrangement allows the temperature of the secondary side outlet 214 to approach the temperature of the primary side inlet 211 and the temperature of the primary side outlet 213 to approach the temperature of the secondary side inlet 212, a deeper heat exchange depth can be achieved to meet complex operating conditions with small temperature difference or high approximation requirements.

[0076] In other examples of embodiments of this application, the primary side inlet 211 may be located below the secondary side inlet 212, and the primary side outlet 213 may be located above the secondary side outlet 214, so that the first coolant is arranged to flow from bottom to top and the second coolant is arranged to flow from top to bottom, so that the first coolant and the second coolant form countercurrent heat exchange inside the heat exchanger 210.

[0077] Figure 8 A schematic diagram of a heat exchanger 210 is shown. Figure 8 Dashed line A indicates the side closer to the first frame 110, and dashed line B indicates the side closer to the second frame 120. See also... Figure 8 In one embodiment of this application, the heat exchanger 210 is inclined relative to the direction of gravity. This arrangement allows at least one of the primary side liquid inlet 211, secondary side liquid inlet 212, primary side liquid outlet 213, and secondary side liquid outlet 214 of the heat exchanger 210 to be located at the lowest point of the entire heat exchanger 210. This allows the interface located at the lowest point to be used as an active drain port by gravity, so that the liquid remaining inside the heat exchanger 210 can be discharged by gravity. This shortens the time required for subsequent drying, improves drying efficiency, and also helps to reduce the risk of bacterial growth due to long-term liquid accumulation.

[0078] See Figure 8In some examples, the tops of the two heat exchangers 210 are inclined toward the second frame 120, making the secondary side inlet 212 the lowest of the four ports of the heat exchanger 210. In other examples, when the second coolant flows from top to bottom inside the heat exchanger 210, the tops of the two heat exchangers 210 are inclined toward the second frame 120, making the secondary side outlet 214 the lowest of the four ports of the heat exchanger 210. In still other examples, when the secondary side inlet 212 and secondary side outlet 214 are located close to the first frame 110, the tops of the two heat exchangers 210 are inclined toward the first frame 110, making either the secondary side inlet 212 or the secondary side outlet 214 the lowest of the four ports of the heat exchanger 210.

[0079] Understandably, when the positions of the four ports of the two heat exchangers 210 are not completely aligned, the tilt direction of each heat exchanger 210 can be selected according to the requirements for residual liquid discharge. For example, the top of one heat exchanger 210 may be tilted towards the second frame 120, while the top of the other heat exchanger 210 may be tilted towards the first frame 110.

[0080] This application embodiment does not restrict the tilt direction of the heat exchanger 210, nor does it restrict the arrangement position of the four ports on the heat exchanger 210: along the direction of gravity, the primary side inlet 211 and the secondary side outlet 214 are higher than the secondary side inlet 212 and the primary side outlet 213, and one of the secondary side inlet 212 and the primary side outlet 213 is lower than the other of the secondary side inlet 212 and the primary side outlet 213. Alternatively, along the direction of gravity, the secondary side inlet 212 and the primary side outlet 213 are higher than the primary side inlet 211 and the secondary side outlet 214, and one of the primary side inlet 211 and the secondary side outlet 214 is lower than the other of the primary side inlet 211 and the secondary side outlet 214.

[0081] See also Figure 7 In one embodiment of this application, the cabinet 100 is used to accommodate two heat exchangers 210. The arrangement of the two heat exchangers 210 improves their heat exchange performance, enhances the unit's expandability, and improves system compatibility. Furthermore, the two heat exchangers 210 are stacked along the direction of gravity. This arrangement utilizes the space along the direction of gravity, allowing two heat exchangers 210 to be accommodated within a minimal projected area, thus improving space utilization and reducing the floor area of ​​the cabinet 100. Simultaneously, the freed-up space provides greater design leeway for other structures, facilitating their size increases, and also provides more space for the installation and removal of other structures, thereby simplifying future maintenance and replacement.

[0082] In addition, in some examples of embodiments of this application, the four pipelines and the two heat exchangers 210 can be connected in parallel by first splitting and then merging the pipelines, thereby reducing the number and length of pipelines and making the pipeline layout more reasonable. The following describes the parallel connection method.

[0083] For example, see Figure 7 The first liquid inlet pipe 511 is used to connect the primary side liquid inlet 211 of the two heat exchangers 210, the second liquid inlet pipe 521 is used to connect the secondary side liquid inlet 212 of the two heat exchangers 210, the first liquid outlet pipe 512 is used to connect the primary side liquid outlet 213 of the two heat exchangers 210, and the second liquid outlet pipe 522 is used to connect the secondary side liquid outlet 214 of the two heat exchangers 210.

[0084] This design eliminates the need for additional piping length in the manifold section, shortens the overall piping length, and reduces the space occupied by piping within the cabinet, resulting in a more compact and rational layout. Furthermore, the reduced number of piping points decreases the number of potential leak points, thereby improving the system's sealing reliability and operational safety.

[0085] See also Figure 7 In one embodiment of this application, a telescopic structure 530 is provided on the first liquid inlet pipe 511, the second liquid inlet pipe 521, the first liquid outlet pipe 512, and the second liquid outlet pipe 522. Taking the second liquid inlet pipe 521 as an example, the telescopic structure 530 can be provided on the portion of the second liquid inlet pipe 521 extending along the second direction Y, so that the length of the telescopic structure 530 can contract and extend along the second direction Y; the telescopic structure 530 can also be provided on the portion of the second liquid inlet pipe 521 extending along the third direction Z, so that the length of the telescopic structure 530 can contract and extend along the third direction Z.

[0086] This design allows for necessary clearance during heat exchanger 210 replacement via telescoping, facilitating the connection or disconnection of pipes to the corresponding interfaces of the heat exchanger 210. Furthermore, it compensates for machining tolerances and assembly errors in the heat exchanger 210 interfaces and individual pipes, preventing interference or poor sealing at connections during assembly and disassembly due to rigid connections. Additionally, the length of the telescoping structure 530 can be flexibly adjusted according to the dimensions of the heat exchanger 210 along the first direction X or the direction of gravity, thereby adapting to heat exchangers 210 with different heat exchange capacities, meeting actual operating conditions, and improving product compatibility.

[0087] It should be noted that the telescopic structure 530 can be installed on any one or more of the first liquid inlet pipe 511, the second liquid inlet pipe 521, the first liquid outlet pipe 512, and the second liquid outlet pipe 522, and one or more telescopic structures 530 can be installed on each pipe. The telescopic structure 530 can be one of the following: a corrugated pipe, a sleeve-type telescopic structure, or a threaded telescopic structure; it can also be an elastic hose structure such as a rubber hose or a silicone hose.

[0088] In one embodiment of this application, Figure 9 A schematic diagram of an expansion tank 250, a first inlet pipe 511, and a second inlet pipe 521 is shown. See [link / reference]. Figure 9 The gap between the first inlet pipe 511 or the second inlet pipe 521 and the first frame 110 along the first direction X is used to accommodate the expansion tank 250. This arrangement ensures that the first inlet pipe 511 or the second inlet pipe 521 will not block the maintenance port 111 between the expansion tank 250 and the first frame 110, thus facilitating front maintenance of the expansion tank 250.

[0089] In one embodiment of this application, the cooling capacity distribution device 1200 further includes a second support structure 320 housed within the cabinet 100, and so on. Figure 9 The second support structure 320 is used to fix the expansion tank 250. The second support structure 320 is slidably connected to the third frame 130, or to the top of the cabinet 100, or to the bottom of the cabinet 100, so that the second support structure 320 can move along the first direction X under the action of external force. For example, the third frame 130 is provided with a guide rail, and a part of the second support structure 320 is engaged in the groove of the guide rail. The second support structure 320 can slide relative to the guide rail and move the expansion tank 250 relative to the guide rail.

[0090] This design reduces the difficulty of maintaining the expansion tank 250 and improves maintenance efficiency. Furthermore, by pulling the expansion tank 250 out of the cabinet 100 through the maintenance port 111 and exposing it, the risk of damage to internal components of the cabinet 100 during disassembly and assembly of the expansion tank 250 can be effectively avoided, thus improving the safety of the internal components.

[0091] See also Figure 4 In one embodiment of this application, the gap between the second outlet pipe 522 and the first frame 110 along the first direction X is used to accommodate the first filter 610. With this arrangement, the second outlet pipe 522 will not form an obstruction between the first frame 110 and the first filter 610. This positional layout makes it convenient for operators to perform frontal maintenance on the first filter 610.

[0092] See also Figure 4In one embodiment of this application, the first filter 610 includes a first maintenance window 611 facing the maintenance port 111, such that the filter element of the first filter 610 passes through the first maintenance window 611 and is pulled out or inserted into the first filter 610 along the first direction X, wherein the first maintenance window 611 refers to the cover on the first filter 610.

[0093] This configuration facilitates external maintenance of the first filter 610, mitigating the limitations and inconveniences caused by the confined space inside the cabinet, reducing the difficulty of the maintenance process, and improving maintenance efficiency.

[0094] See also Figure 4 In one embodiment of this application, the first filter 610 extends along the first direction X. This arrangement allows the space of the cabinet 100 along the first direction X to accommodate the length of the first filter 610, thereby reducing the space occupied by the maintenance port 111 of the first filter 610.

[0095] In addition, the inlet of the first filter 610 is directed along the first direction X toward the second outlet pipe 522 to receive the second coolant, and the outlet of the first filter 610 is directed along the second direction Y toward the third frame 130 to output the second coolant.

[0096] This configuration allows the portion of the second outlet pipe 522 used to connect to the inlet of the first filter 610 to run along the first direction X, while the other portion of the second outlet pipe 522 used to connect to the outlet of the first filter 610 runs along the second direction Y. This improves the problem of pipe winding or crossing caused by the concentration of pipes, reduces pipe length, and lowers costs.

[0097] In one embodiment of this application, see also: Figure 4 The gap between the second inlet pipe 521 and the first frame 110 along the first direction X is used to accommodate the second filter 620. With this arrangement, the second inlet pipe 521 will not form an obstruction between the first frame 110 and the second filter 620, which makes it easier for operators to maintain the second filter 620.

[0098] See also Figure 4 In one embodiment of this application, the second filter includes a second maintenance window 621 facing the top of the cabinet 100, allowing the filter element of the second filter to pass through the second maintenance window 621 and be pulled out or inserted into the second filter 620 along the third direction Z. The second maintenance window 621 refers to the cover of the second filter 620. With this configuration, the length direction of the filter element of the second filter 620 is parallel to the third direction Z, allowing the operator to perform the insertion and removal of the filter element with one hand, effectively reducing the difficulty of inserting and removing the filter element and improving maintenance efficiency.

[0099] The cooling capacity distribution device 1200 provided in this embodiment also includes a plurality of sensors 230, see [link to documentation]. Figure 4 A portion of the multiple sensors 230 are distributed in the primary side pipeline 510, another portion of the multiple sensors 230 are distributed in the secondary side pipeline 520, and yet another portion of the multiple sensors 230 can also be distributed in various devices within the cabinet 100, such as heat exchanger 210, pump body 240, or expansion tank 250. These sensors 230 are used to detect the state of the first coolant and the second coolant. For example, a temperature sensor 230 for detecting temperature, a pressure sensor 230 for detecting pressure, and a flow sensor 230 for detecting flow rate can be set to detect the specific state of the second coolant and the first coolant, so as to provide support for the operation and control of the cooling capacity distribution device 1200.

[0100] In one embodiment of this application, the power supply device 220 includes a first electronic control component 221, a second electronic control component 222, and a tray 223, wherein the rated voltage of the first electronic control component 221 is greater than the rated voltage of the second electronic control component 222. Figure 10 A schematic diagram of a power supply device 220 is shown from one perspective. Figure 10 The uppermost dashed box A contains the second electronic control component 222, and the lowermost dashed box B contains the first electronic control component 221. (See also...) Figure 10 In this embodiment of the application, the first electronic control component 221 is used to supply power to the pump body 240 and the second electronic control component 222. The first electronic control component 221 includes a power module 2211, a frequency converter 2212, a filter 2213 and a circuit breaker 2214, etc.

[0101] Figure 11 A schematic diagram of a power supply device 220 is shown from another perspective. (See attached image) Figure 11 The second electrical control component 222 is located inside the tray 223. The second electrical control component 222 is used to power multiple sensors 230. The second electrical control component 222 can integrate components such as controller 2221, auxiliary power module 2222, single board 2223, fuse 2224, relay 2225, and terminal block 2226. The tray 223 is located inside the first support structure 310, and the first tray 223 can be pulled out or inserted into the first support structure 310 along the first direction X. In addition, the first electrical control component 221 is located below the tray 223 along the direction of gravity, and at least a part of the first electrical control component 221 can be pulled out or inserted into the first support structure 310 along the first direction X. This arrangement can effectively improve the limitations and inconveniences caused by the narrow space inside the cabinet for maintenance, reduce the difficulty of the maintenance process, improve maintenance efficiency, and facilitate the hot-swapping of various components in the first electrical control component 221.

[0102] In addition, the tray 223 can separate strong and weak currents, reduce the influence of strong current in the first electronic control component 221 on weak current in the second electronic control component 222, and thus improve the stability and reliability of the first electronic control component 221 and the second electronic control component 222.

[0103] In one embodiment of this application, tray 223 is also used to accommodate cable chain 224 and cable 225. Figure 12 A schematic diagram of a power supply device 220 is shown from another perspective, wherein the bold dashed line represents cable 225. See also... Figure 12 Cable 225 is used to connect controller 2221 and multiple sensors 230. One end of cable chain 224 is fixed to the top of first support structure 310, and the other end of cable chain 224 is fixed to tray 223. Cable chain 224 can move and bend along the first direction X with tray 223. At least part of cable 225 located in power supply device 220 is located in cable chain 224. Cable chain 224 is used to bind cable 225 and limit the direction of movement of cable 225.

[0104] By setting up the cable chain 224, the cable 225 can be effectively protected, reducing the risk of the cable 225 coming into contact with other parts during movement. The rotatable nature of the cable chain 224 can also help the cable 225 to be quickly reset, improving the smoothness of tray 223 insertion, thereby improving maintenance efficiency.

[0105] A second aspect of this application provides a data center 1000, which includes a cooling distribution device 1200 and an artificial intelligence (AI) server 1100. See also... Figure 1 The cooling distribution device 1200 is used to transfer the second coolant to the server 1100 or receive the second coolant from the server 1100. During operation, the cooling distribution device 1200 delivers the low-temperature second coolant (e.g., deionized water or ethylene glycol), which is the cooling capacity, to each server 1100. After the second coolant is heated in each server 1100, it becomes a high-temperature second coolant. The high-temperature second coolant (i.e., heat) flows back to the cooling distribution device 1200 along the connecting pipe between each server 1100 and the cooling distribution device 1200 to enter the next cycle.

[0106] The Server 1100 is a high-performance computer specifically designed for artificial intelligence applications, used to train AI models or perform inference using AI models. Through its advanced hardware architecture, the Server 1100 is able to quickly process large-scale data and complex computing tasks to meet the computing resource requirements of AI applications. For a detailed explanation of the Server 1100, please refer to the relevant technical documentation, which will not be repeated here.

[0107] As a liquid, the second coolant has a higher thermal conductivity and specific heat capacity than air.
