Abstract

This application provides a cold energy distribution device and a liquid cooling system. The cabinet of the cold energy distribution device is used to house a heat exchanger. The heat exchanger is arranged at an angle and includes an inlet side and an outlet side, which are opposite to each other along a first direction. The primary and secondary inlets of the heat exchanger are located on the inlet side, and the primary and secondary outlets are located on the outlet side. By tilting the heat exchanger, at least one of the primary, secondary, and primary outlets is located at the lowest point of the entire heat exchanger. Gravity can be used to make this lowest-point interface an active drain outlet, allowing residual pure water inside the heat exchanger to drain out under gravity. This tilted draining method reduces the amount of residual liquid in the heat exchanger, thereby significantly shortening the subsequent drying time, improving drying efficiency, and also helping to reduce the risk of bacterial growth due to long-term liquid accumulation.

Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, and in particular to a cooling capacity distribution device and a liquid cooling system. Background Technology

[0002] The heat exchanger is the core component of the cooling distribution unit, used to transfer the first and second coolants for heat exchange. The first coolant flows between the heat exchanger and the cold source, while the second coolant flows between the heat exchanger and the liquid-cooled server. Before the cooling distribution unit leaves the factory, the sealing of the heat exchanger and its connected pipes needs to be checked. After inspection, the interior of the heat exchanger needs to be cleaned. However, existing heat exchangers often retain liquid after cleaning, and this residue is difficult to drain and dry. If the residual liquid is not thoroughly dried before the cooling distribution unit leaves the factory, bacteria and microorganisms can easily grow at the bottom of the heat exchanger, seriously threatening the safe and stable operation of the server. Summary of the Invention

[0003] This application provides a cold energy distribution device and a liquid cooling system, which solves the problems of residual liquid easily accumulating at the bottom of the heat exchanger of existing cold energy distribution devices, leading to bacterial growth, or the long drying time of the residual liquid.

[0004] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, this application provides a cooling capacity distribution device. The cabinet of the cooling capacity distribution device is used to house a heat exchanger. The heat exchanger is arranged at an angle and includes an inlet side and an outlet side, which are opposite to each other along a first direction perpendicular to the direction of gravity. 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 the secondary side inlet are located on the inlet side, and the primary side outlet and the secondary side outlet are located on the outlet side. The primary side inlet and the primary side outlet are respectively used to connect to a primary side inlet pipe and a primary side outlet pipe to transmit a first coolant. The secondary inlet and secondary outlet are used to connect the secondary inlet pipe and the secondary outlet pipe, respectively, to transmit the second coolant. Specifically, along the direction of gravity, the primary inlet and secondary outlet are higher than the secondary inlet and primary outlet, and one of the secondary inlet and primary outlet is lower than the other; or, along the direction of gravity, the secondary inlet and primary outlet are higher than the primary inlet and secondary outlet, and one of the primary inlet and secondary outlet is lower than the other.

[0005] By tilting the heat exchanger so that at least one of its primary inlet, secondary inlet, primary outlet, and secondary outlet is located at the lowest point of the entire heat exchanger, gravity can be used to activate this lowest-point interface as an active drain, allowing residual purified water inside the heat exchanger to drain out automatically. This tilted draining method reduces the amount of residual liquid in the heat exchanger, significantly shortening the subsequent drying time and improving drying efficiency. It also helps reduce the risk of bacterial growth due to long-term liquid accumulation.

[0006] In some embodiments, a drain port is provided on the secondary side liquid inlet pipe or the primary side liquid outlet pipe connected to the lower of the secondary side liquid inlet and the primary side liquid outlet, and the drain port is used to discharge the accumulated liquid inside the heat exchanger; or, a drain port is provided on the primary side liquid inlet pipe or the secondary side liquid outlet pipe connected to the lower of the primary side liquid inlet and the secondary side liquid outlet, and the drain port is used to discharge the accumulated liquid inside the heat exchanger.

[0007] This application provides a drain port on the inlet or outlet pipe connected to the interface located at the lowest point of the heat exchanger. This allows residual liquid inside the heat exchanger to be drained without disconnecting the pipe from the heat exchanger. Compared to methods requiring pipe removal, this design improves the convenience and efficiency of the draining operation, avoids the risk of seal failure, pipe damage, or leakage caused by frequent disassembly and reassembly, and reduces the impact of maintenance operations on normal system operation, minimizing maintenance downtime.

[0008] In some embodiments, the cabinet includes a first frame and a second frame, which are arranged opposite to each other along a second direction, which is perpendicular to the first direction and the direction of gravity. The first frame includes a maintenance port. The distance between the first frame and the heat exchanger along the second direction is greater than the distance between the heat exchanger and the second frame. The gap between the liquid inlet side and the cabinet along the first direction is used to accommodate the primary liquid inlet pipe and the secondary liquid inlet pipe. The gap between the liquid outlet side and the cabinet along the first direction is used to accommodate the primary liquid outlet pipe and the secondary liquid outlet pipe.

[0009] In this application, the heat exchanger has passed inspection before leaving the factory and requires less maintenance during use, while the replenishment tank, power supply unit, and circulation pump require frequent maintenance and repair. Therefore, the heat exchanger is positioned closer to the second frame than the first frame along the first direction. On one hand, this allows for single-sided maintenance of the cooling distribution device, meaning maintenance can be performed solely through the maintenance port, eliminating the need to reserve maintenance space behind the second frame when arranging the cooling distribution device, thus reducing its space occupancy in the data center. On the other hand, placing the frequently maintained replenishment tank, power supply unit, and circulation pump near the maintenance port reduces maintenance difficulty, freeing maintenance personnel from entering the cabinet or performing maintenance around multiple sides of the cooling distribution device. Furthermore, since maintenance space is required for the replenishment tank, power supply unit, and circulation pump, concentrating them near the maintenance port and placing the heat exchanger away allows them to share maintenance space, optimizing the cabinet's spatial layout and improving space utilization.

[0010] Furthermore, this application places the heat exchanger in the center of the cabinet, connecting the primary and secondary liquid inlet pipes along one side of the heat exchanger in the first direction, and connecting the primary and secondary liquid outlet pipes along the other side of the heat exchanger in the first direction. On the one hand, this allows for better utilization of the cabinet's space in the first direction, enabling the heat exchanger and its connected pipes to be evenly distributed within the cabinet. On the other hand, it avoids crossings and interference between the inlet and outlet pipes, thus eliminating the need to extend pipe lengths or occupy additional space due to avoidance. In addition, it facilitates the separate installation of the inlet and outlet pipes, making maintenance work simpler and more convenient for installers.

[0011] In some embodiments, the cabinet is used to house two heat exchangers, which are stacked along the direction of gravity, wherein: a primary side liquid inlet pipe is used to connect the primary side liquid inlets of the two heat exchangers, and a primary side liquid outlet pipe is used to connect the primary side liquid outlets of the two heat exchangers; a secondary side liquid inlet pipe is used to connect the secondary side liquid inlets of the two heat exchangers, and a secondary side liquid outlet pipe is used to connect the secondary side liquid outlets of the two heat exchangers.

[0012] This application stacks two heat exchangers along the direction of gravity, which on the one hand improves the heat exchange capacity of the cold distribution device. On the other hand, it makes full use of the space along the direction of gravity, thereby reserving sufficient space in the first direction for the primary side liquid inlet pipe, the secondary side liquid inlet pipe, the primary side liquid outlet pipe, and the secondary side liquid outlet pipe, thus improving space utilization.

[0013] In some embodiments, the cabinet is used to house the first support member, which is fixed to the top of the cabinet. The cabinet includes a third frame and a fourth frame, which are arranged opposite to each other along a first direction. The first support member is located on both sides of the heat exchanger along the first direction for clamping the heat exchanger. The first support member includes multiple through holes. The primary side liquid outlet pipe and the secondary side liquid outlet pipe pass through a portion of the through holes and are fixed to the third frame. The primary side liquid inlet pipe and the secondary side liquid inlet pipe pass through another portion of the through holes and are fixed to the fourth frame.

[0014] The first support member in this application is fixed by the top of the cabinet, thereby defining its position and clamping and constraining the inclined heat exchanger from both sides, thereby achieving stable support for the heat exchanger, preventing the heat exchanger from overturning during use or transportation, and avoiding insufficient operational stability due to vibration or fluid pulsation.

[0015] Based on this, the first support component also provides lateral fixation for the heat exchanger, thereby effectively controlling the heat exchanger's own machining tolerances and the cumulative errors generated during assembly within a preset controllable range. This avoids interference with other components due to improper heat exchanger installation, or failure to install tightly with the inlet and outlet liquid pipelines.

[0016] Furthermore, this application also fixes the primary side liquid outlet pipeline and the secondary side liquid outlet pipeline to the third frame, and the primary side liquid inlet pipeline and the secondary side liquid inlet pipeline to the fourth frame, thereby preventing shaking in the middle area of ​​the pipeline and ensuring the connection reliability and operational stability of the entire liquid circuit system.

[0017] In some embodiments, the cabinet is used to house a second support member, which is fixed to a first support member. The second support member is used to fix a replenishment tank, which is used to replenish at least one of a first coolant or a second coolant to the heat exchanger. The replenishment tank is located in the gap between the second support member and the first frame along the second direction, and the heat exchanger is located in the gap between the second support member and the second frame along the second direction.

[0018] This application uses a second support member to fix the replenishment tank, which can prevent the replenishment tank from shaking during use and improve structural stability. At the same time, fixing the second support member to the first support member, the two form an integral structure to fix the heat exchanger and the replenishment tank together, which can reduce the space occupied by the integral structure inside the cabinet, thereby making room for the arrangement of other components.

[0019] Heat exchangers are large in size and weight, especially when they need to be tilted or stacked in the direction of gravity. To ensure their stable placement within the cabinet, supports are required. Similarly, the replenishment tank, due to its large volume and weight of storing primary or secondary coolant, also requires supports. This application addresses this by incorporating a second support member. This provides dual support and fixation for both the heat exchanger and the replenishment tank, simplifying the cabinet's support structure. Furthermore, the second support member also partitions the cabinet space in a second direction, positioning the heat exchanger and replenishment tank on opposite sides of the second support member. This clarifies the cabinet's spatial arrangement and facilitates maintenance personnel's work.

[0020] In some embodiments, the cabinet is used to accommodate a third support member, which is fixed to the bottom of the cabinet and to a third frame and a fourth frame. The third support member is located between the heat exchanger and the bottom of the cabinet along a third direction, which is perpendicular to the first and second directions. The third support member is used to fix and support the heat exchanger and the first support member.

[0021] This application achieves more stable and reliable support by simultaneously fixing the third support member to both the third and fourth frames, creating a flat supporting plane on its upper surface. This plane allows for the direct placement of the bottom of the heat exchanger or the first support member. Furthermore, the third support member is positioned between the heat exchanger and the bottom of the cabinet, leaving a space for the subsequent placement of the circulating pump. This balances support stability with efficient internal space utilization and ease of assembly.

[0022] In some embodiments, the gap between the third support member and the bottom of the cabinet along the third direction is used to accommodate a circulation pump for driving the flow of a second coolant, and a portion of the circulation pump along the second direction protrudes from the heat exchanger and extends toward the first frame.

[0023] By placing the heavy circulating pump at the bottom of the cabinet, this application can lower the overall center of gravity of the device, improve the stability of the whole machine during transportation and operation, and avoid overturning due to the high center of gravity.

[0024] In this application, the heat exchanger is positioned above the circulating pump along a third direction. When the second coolant is pressurized by the circulating pump below and delivered to the heat exchanger above, its own gravity creates a downward static pressure in the pipeline during the upward transport process. This static pressure provides a stable back pressure at the secondary side inlet of the heat exchanger, allowing the second coolant to fill the various plate channels inside the heat exchanger evenly and stably. This reduces flow deviation or localized air blockage caused by pressure fluctuations at the secondary side inlet, thereby improving heat exchange efficiency.

[0025] Based on this, by extending part of the circulating pump into the first frame, the circulating pump can be replaced or maintained using the maintenance port opened on the first frame, thereby improving the ease of maintenance of the device.

[0026] In some embodiments, the cabinet is used to house two circulating pumps, a first manifold, and a second manifold. The two circulating pumps are arranged along a first direction. The inlets of the two circulating pumps are used to receive a second coolant through the first manifold, and the outlets of the two circulating pumps are used to output the second coolant to the second manifold. The second manifold is used to transfer the second coolant to the heat exchanger. The first and second manifolds are distributed between the heat exchanger and the first frame along a second direction, and the second manifold is located between the first manifold and the heat exchanger along the second direction.

[0027] This application, by setting up two circulation pumps, can both expand the flow range of the second coolant flowing through the pipeline and provide greater circulation power for the second coolant, and can also arrange the two circulation pumps in parallel to achieve mutual backup and provide redundancy.

[0028] This application splits the flow on both sides near the two circulating pumps and then merges it through the first and second manifolds, so that a single pipe can simultaneously connect the corresponding inlet and outlet ports of the two circulating pumps. This eliminates the need for additional pipe length in the manifold section, thereby shortening the overall pipe length, reducing the pipe's occupation of the cabinet's internal space, and making the layout more compact and reasonable.

[0029] This application achieves spatial separation between the manifold and the inlet / outlet pipes by arranging the first and second manifolds between the heat exchanger and the first frame, while the four inlet / outlet pipes on both sides of the heat exchanger are arranged between the heat exchanger and the third or fourth frame. The two pipe sections are arranged independently, without needing to make way for each other, thus simplifying the overall pipe layout and shortening the length of all pipes. This reduces the space occupied by the pipes inside the cabinet, providing space for replacing larger heat exchangers.

[0030] Meanwhile, the second manifold is located between the first manifold and the heat exchanger, making the second manifold closer to the heat exchanger. This not only shortens the pipe length between the second manifold and the heat exchanger, but also enables spatial separation of the first and second pipes in the second direction. This arrangement simplifies the pipe layout and avoids cross-interference between the two pipes, thus eliminating the need to extend the pipes or occupy additional space due to avoidance. This reduces the space occupied by the pipes in the second direction, providing space for replacing larger heat exchangers.

[0031] In some embodiments, the cabinet is used to house a first pipe and a second pipe, the first pipe being used to supply a first coolant to a circulation pump, and the second pipe being used to receive a second coolant from the circulation pump. The first pipe and the second pipe include a first segment and a second segment extending in a third direction, and the first segment and the second segment are detachably connected. If the first segment and the second segment are detached, the circulation pump is used to move in a second direction under the action of an external force.

[0032] In this application, both the first and second pipelines extend along a third direction and are each constructed as two detachably connected sections. When the circulating pump requires maintenance or replacement, the detachable connection between the corresponding two pipeline sections can be disconnected without disassembling any other pipelines or components, thus separating the circulating pump from other parts. Because the pipelines extend along a third direction and their detachable connections are vertically arranged, the circulating pump can be directly moved out of the cabinet along a second direction after disconnection without interfering with the disconnected pipeline, allowing for easy removal. This design avoids the cumbersome operation of cutting or re-welding the first and second pipelines required in traditional maintenance, simplifying the operation, reducing maintenance difficulty, and improving work efficiency. Therefore, while ensuring a compact system pipeline layout, it enhances the convenience and efficiency of circulating pump maintenance.

[0033] In some embodiments, the cabinet is used to house a fourth support member and a power supply device. The fourth support member is fixed to the top of the cabinet and has an opening facing the maintenance port. The fourth support member is used to house the power supply device, which is used to be pulled out or inserted into the fourth support member through the opening in the second direction under the action of an external force. The power supply device is used to supply power to electrical equipment inside the cabinet.

[0034] This application, by fixing the fourth support to the top of the cabinet and using the fourth support to house the power supply device, can prevent leakage in the cooling distribution device from affecting the power supply device, thereby achieving the effect of water and electricity separation and improving the electrical safety of the whole machine.

[0035] The power supply device can be installed and removed along the second direction within the fourth support member, facilitating flexible operation when connecting to an external power source. Furthermore, when a fault occurs in the internal circuit of the power supply device, it can be quickly pulled out from the maintenance port along the second direction without disassembling surrounding components, making inspection and maintenance convenient.

[0036] In some embodiments, the gap between one of the circulating pumps or power supply devices along the first direction and the third frame is used to accommodate the first filter, and the gap between the other circulating pump or power supply device along the first direction and the third frame is used to accommodate the primary side liquid outlet pipe and the secondary side liquid outlet pipe, wherein the primary side liquid outlet pipe is used to receive the first coolant from the heat exchanger, the secondary side liquid outlet pipe is used to receive the second coolant from the heat exchanger, and the first filter is connected to the secondary side liquid outlet pipe and is used to filter the second coolant.

[0037] In this application, the first filter and the secondary side liquid outlet pipeline are placed in the gap between the circulating pump or power supply device and the third frame, making full use of the space. At the same time, the first filter is arranged close to the secondary side liquid outlet pipeline, thereby shortening the length of the connecting pipeline required to connect the first filter to the secondary side liquid outlet pipeline and reducing flow resistance and leakage risk.

[0038] In some embodiments, the cabinet is used to house a plurality of first filters arranged in a third direction and extending in a second direction. Each first filter includes a maintenance window facing a maintenance port, such that the filter element of the first filter passes through the maintenance window and is pulled out or inserted into the first filter in the second direction.

[0039] In this application, multiple first filters extend along the second direction, and the maintenance windows are all set facing the maintenance port, so that the filter element of the first filter can be directly pulled out from the maintenance window along the second direction, and then replaced or maintained through the maintenance port of the first frame, without disassembling other parts. The maintenance operation is simple and convenient, further improving the maintainability and space utilization of the system.

[0040] In some embodiments, the gap between one of the circulating pumps or power supply devices along the first direction and the fourth frame is used to accommodate an expansion tank, and the gap between the other circulating pump or power supply device along the first direction and the fourth frame is used to accommodate a primary side inlet pipe and a secondary side inlet pipe, wherein the primary side inlet pipe is used to transmit a first coolant to the heat exchanger, the secondary side inlet pipe is used to transmit a second coolant to the heat exchanger, and the expansion tank is used to regulate the pressure of the second coolant.

[0041] In this application, the expansion tank and the secondary side liquid inlet pipeline are arranged in the gap between the circulating pump or power supply device and the fourth frame, making full use of the space. At the same time, the expansion tank is arranged close to the secondary side liquid inlet pipeline, thereby shortening the length of the connecting pipeline required to connect the expansion tank to the secondary side liquid inlet pipeline and reducing flow resistance and leakage risk.

[0042] In some embodiments, the gap between the primary side inlet pipe and the top of the cabinet, or between the primary side inlet pipe and the bottom of the cabinet, is used to accommodate a second filter, which is connected to the primary side inlet pipe and used to filter the first coolant.

[0043] In this application, the second filter is placed in the gap between the primary side liquid inlet pipe and the top or bottom of the cabinet, which can make full use of the space. At the same time, the second filter is arranged close to the primary side liquid inlet pipe, thereby shortening the length of the connecting pipe required to connect the second filter to the primary side liquid inlet pipe and reducing flow resistance and leakage risk.

[0044] In some embodiments, the second frame is used to accommodate the fifth support member, which is fixed to the top and bottom of the cabinet respectively. Along the second direction, the orthographic projection of a portion of the fifth support member is located within the outline of the heat exchanger, and the orthographic projection of another portion of the fifth support member is located within the outline of the third support member.

[0045] This application improves the strength of the second frame structure by fixing the fifth support member to the top and bottom of the cabinet respectively, allowing the fifth support member or the second frame as a whole to provide a buffering effect when the heat exchanger overturns. Furthermore, the fifth support member also applies a limiting effect along the second direction to the third support member. Since the third support member is fixed to the heat exchanger via the first support member, this limiting effect effectively restricts the displacement of the third support member. Therefore, when the heat exchanger is subjected to impact or vibration, energy is transferred via the first support member to the fifth support member for absorption and dispersion, further enhancing the buffering effect on the heat exchanger.

[0046] In some embodiments, the tilt angle of the heat exchanger relative to a third direction is 5°-10°.

[0047] The tilt angle of the heat exchanger needs to balance the drainage effect of residual liquid with the stability of the overall structure. If the tilt angle is too small, the flow of residual liquid inside the heat exchanger will be insignificant, making it difficult to effectively drain the residual liquid, which may lead to corrosion or a decrease in heat exchange efficiency over long-term use. If the tilt angle is too large, due to the large weight of the heat exchanger itself, the center of gravity shift will increase, making it prone to tipping over. At the same time, it will increase the difficulty and cost of fixing the first support component, and the structural strength requirements of the first support component will also be correspondingly increased. In this application, the tilt angle of the heat exchanger is controlled within the range of 5° to 10°. Within this angle range, the residual liquid can flow smoothly to the lowest port and be discharged under the action of gravity, while avoiding instability caused by an excessively large tilt angle.

[0048] Secondly, this application provides a liquid cooling system, including: a liquid cooling server and a cooling capacity distribution device as described above, wherein the liquid cooling server includes a cold plate; a secondary side liquid inlet pipe and a secondary side liquid outlet pipe are used to connect a heat exchanger and a cold plate to transmit a second coolant.

[0049] The cooling distribution device in this application is used to cool the second coolant in the cold plate of the liquid-cooled server. Through efficient heat exchange, the heat carried by the second coolant is discharged in time, thereby effectively reducing the temperature of the cold plate and the core components of the liquid-cooled server, and thus improving the power density and operational stability of the liquid-cooled server.

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0053] Figure 1 A schematic diagram of a liquid cooling system provided in an embodiment of this application is shown as an example. Figure 1 As shown, the cooling capacity distribution device 100 is connected to the cold source 300 via a primary side pipe 200 and to the cold plate 510 inside the liquid-cooled server 500 via a secondary side pipe 400. The cooling capacity distribution device 100 in this application is used to cool the coolant inside the cold plate 510 in the liquid-cooled server 500.

[0054] Specifically, the primary side pipeline 200 includes a primary side liquid inlet pipeline and a primary side liquid outlet pipeline, which are used to connect the heat exchanger and the cold source 300 to transmit cooling water. The secondary side pipeline 400 includes a secondary side liquid inlet pipeline and a secondary side liquid outlet pipeline, which are used to connect the heat exchanger and the cold plate 510 to transmit coolant.

[0055] This application provides a cold energy distribution device that can be applied to the liquid cooling system described above. By tilting the heat exchanger, the cold energy distribution device can reduce the amount of residual liquid in the heat exchanger, thereby significantly shortening the time required for subsequent drying, improving drying efficiency, and also helping to reduce the risk of bacterial growth due to long-term liquid accumulation. The specific implementation method is as follows.

[0056] Figure 2 A schematic diagram of a cooling capacity distribution device provided in an embodiment of this application is shown as an example. For clarity of illustration, [the diagram is omitted]. Figure 2 The first frame 101 is hidden in the middle. In this example, the cooling capacity distribution device 100 includes: a cabinet 1, which is used to house multiple components such as heat exchanger, liquid replenishment tank, power supply device, first filter, second filter, expansion tank, circulation pump and pipeline, and can provide stable physical support for each component and realize water and electricity isolation between each component, while meeting the protection and heat dissipation requirements to ensure the safe and reliable operation of the system.

[0057] Figure 3 An exemplary structural schematic diagram of a cabinet provided in an embodiment of this application is shown, wherein, for clarity of illustration, Figure 3 The first frame 101 is hidden in the figure. In this example, the cabinet 1 includes a first frame 101 (not shown in this figure), a second frame 102, a third frame 103, a fourth frame 104, a fifth frame 105, and a sixth frame 106. The first frame 101 and the second frame 102 are arranged opposite each other along a second direction b, the third frame 103 and the fourth frame 104 are arranged opposite each other along a first direction a, and the fifth frame 105 and the sixth frame 106 are arranged opposite each other along a third direction c. The first direction and the second direction are perpendicular to the direction of gravity, and the third direction is perpendicular to the first direction and the second direction.

[0058] The first frame 101 includes a maintenance port, through which multiple components inside the cabinet 1, such as the replenishment tank, power supply device, first filter, second filter, expansion tank, circulation pump and sensor, can be replaced and maintained.

[0059] The first frame 101 can be a door panel, which is rotatably connected to the third frame 103 or the fourth frame 104 to form a maintenance opening. Alternatively, the first frame 101 can be fixedly connected to the other frames, and a special maintenance opening can be provided on the first frame 101, with a door panel rotatably installed at the opening to form a maintenance opening.

[0060] Continue as Figure 3 As shown, the cabinet 1 includes two inlets 107 and two outlets 108. The two inlets 107 and two outlets 108 are used to connect the primary side liquid inlet pipe, the secondary side liquid inlet pipe, the primary side liquid outlet pipe and the secondary side liquid outlet pipe inside the cabinet 1 to the cold source 300 and the cold plate 510 of the liquid-cooled server 500 outside the cabinet 1, respectively, so as to realize the heat transfer and circulation between the primary side and the secondary side pipes.

[0061] In some examples of embodiments of this application, the two inlets 107 and the two outlets 108 are located at the bottom of the cabinet 1, that is, on the sixth frame 106, so that the coolant in the pipeline can flow out of the cabinet 1 naturally by gravity, thereby reducing power loss.

[0062] In other examples of embodiments of this application, the two inlets 107 and the two outlets 108 may also be located at the top of the cabinet 1, i.e. on the fifth frame 105, so that no space needs to be reserved at the bottom of the cabinet 1 for pipe routing, thereby reducing the overall height of the cabinet 1.

[0063] The two inlets 107 include a primary inlet 1071 and a secondary inlet 1072. The primary inlet 1071 is used to connect to the primary liquid inlet pipeline, and the secondary inlet 1072 is used to connect to the secondary liquid inlet pipeline. The two outlets 108 include a primary outlet 1081 and a secondary outlet 1082. The primary outlet 1081 is used to connect to the primary liquid outlet pipeline, and the secondary outlet 1082 is used to connect to the secondary liquid outlet pipeline.

[0064] In some examples of embodiments of this application, returning to... Figure 1 As shown, the cold source 300 and the liquid-cooled server 500 are located on both sides of the cold distribution device 100, and the first frame 101 (not shown in this figure) of the cold distribution device 100 faces the cold source 300, and the second frame 102 (not shown in this figure) faces the liquid-cooled server 500.

[0065] Based on this, continue as follows Figure 3As shown, along the second direction b, the primary side entrance 1071 and primary side exit 1081 of the cabinet 1 are located in front of the secondary side entrance 1072 and secondary side exit 1082, that is, the primary side entrance 1071 and primary side exit 1081 are set closer to the first frame 101 (not shown in this figure), while the secondary side entrance 1072 and secondary side exit 1082 are set closer to the second frame 102.

[0066] Based on this layout, the connecting pipes between the primary side inlet 1071 and the primary side outlet 1081 and the cold source 300 can be made shorter. Similarly, the connecting pipes between the secondary side inlet 1072 and the secondary side outlet 1082 and the liquid-cooled server 500 can also be made shorter. This can save the total length of the pipes, reduce the cost of pipe materials, and reduce the pressure drop loss of the first and second coolants during the flow process, thereby improving the system's energy efficiency and operational stability.

[0067] In other examples of embodiments of this application, when the cold source 300 and the liquid-cooled server 500 are located on opposite sides of the cold distribution device 100, and the first frame 101 of the cold distribution device 100 faces the liquid-cooled server 500 and the second frame 102 faces the cold source 300, along the second direction b, the secondary side inlet 1072 and the secondary side outlet 1082 of the cabinet 1 are located in front of the primary side inlet 1071 and the primary side outlet 1081, that is, the secondary side inlet 1072 and the secondary side outlet 1082 are set closer to the first frame 101, while the primary side inlet 1071 and the primary side outlet 1081 are set closer to the second frame 102, so that the connecting pipes between the primary side inlet 1071 and the primary side outlet 1081 and the cold source 300, and the connecting pipes between the secondary side inlet 1072 and the secondary side outlet 1082 and the liquid-cooled server 500 are all set to be shorter.

[0068] Return to Figure 2 As shown, the cabinet 1 is used to house the heat exchanger 2, which is the core heat exchange component of the cold energy distribution device 100 and is used to achieve efficient heat exchange between the primary side pipeline 200 (not shown in this figure) and the secondary side pipeline 400 (not shown in this figure).

[0069] Figure 4 An exemplary schematic diagram of a heat exchanger provided in an embodiment of this application is shown from a first angle. Figure 5An exemplary schematic diagram of a heat exchanger provided in this application embodiment is shown from a second angle. Both the first and second angles are viewing directions from the second frame 102 of the cold energy distribution device 100 towards the first frame 101. The first angle emphasizes the two interfaces connecting the heat exchanger 2 to the inlet pipe, while the second angle emphasizes the two interfaces connecting the heat exchanger 2 to the outlet pipe. In this example, the heat exchanger 2 includes an inlet side 201 and an outlet side 202, and the inlet side 201 and the outlet side 202 are opposite to each other along a first direction a.

[0070] It is understandable that the heat exchanger 2 is composed of multiple spaced plates stacked together, with the multiple plates arranged sequentially along the first direction a, that is, the thickness direction of the heat exchanger 2 is parallel to the first direction a.

[0071] Continue as Figure 4 and Figure 5 As shown, the heat exchanger 2 includes a primary side liquid inlet 203, a secondary side liquid inlet 204, a primary side liquid outlet 205, and a secondary side liquid outlet 206. The primary side liquid inlet 203 and the primary side liquid outlet 205 are respectively used to connect the primary side liquid inlet pipeline and the primary side liquid outlet pipeline to transmit the first coolant. The secondary side liquid inlet 204 and the secondary side liquid outlet 206 are respectively used to connect the secondary side liquid inlet pipeline and the secondary side liquid outlet pipeline to transmit the second coolant.

[0072] Specifically, the primary side liquid inlet 203 and the secondary side liquid inlet 204 are located on the liquid inlet side 201, and the primary side liquid outlet 205 and the secondary side liquid outlet 206 are located on the liquid outlet side 202.

[0073] This application minimizes the space occupied by the heat exchanger 2 in the first direction a by arranging the liquid inlet side 201 and the liquid outlet side 202 of the heat exchanger 2 opposite to each other along the first direction a, and distributing the primary side liquid inlet 203 and the secondary side liquid inlet 204 on the liquid inlet side 201, and the primary side liquid outlet 205 and the secondary side liquid outlet 206 on the liquid outlet side 202. This provides sufficient space for the subsequent arrangement of the liquid inlet pipe and the liquid outlet pipe along both sides of the first direction a, and also facilitates the connection and maintenance of the subsequent liquid inlet pipe and the liquid outlet pipe, thereby improving the compactness and operability of the overall structure.

[0074] Furthermore, the primary and secondary liquid inlet pipes are located on the liquid inlet side 201 of heat exchanger 2, while the primary and secondary liquid outlet pipes are located on the liquid outlet side 202 of heat exchanger 2. This allows for only two pipes on each of the liquid inlet side 201 and liquid outlet side 202 of heat exchanger 2, thus centrally arranging the four pipes in separate zones. Because the pipes are arranged in separate zones, and pipes on the same side do not interfere with each other, the pipe design is significantly simplified, saving space occupied by the pipes and consequently reducing the overall size of the unit.

[0075] In some examples of embodiments of this application, the primary side inlet 203 is located above the inlet side 201, the secondary side inlet 204 is located below the inlet side 201, the primary side outlet 205 is located below the outlet side 202, and the secondary side outlet 206 is located above the outlet side 202.

[0076] This embodiment employs a flow arrangement where the first coolant enters from the top and exits from the bottom, while the second coolant enters from the bottom and exits from the top, creating a counter-current heat exchange between the first and second coolants within the heat exchanger 2. In this counter-current mode, the logarithmic mean temperature difference between the first and second coolants is maximized, thereby achieving the highest heat exchange capacity under the same heat exchange area and flow rate conditions, thus improving heat exchange efficiency.

[0077] Furthermore, since the counter-current arrangement is conducive to the temperature of the secondary side outlet 206 approaching the temperature of the primary side inlet 203 and the temperature of the primary side outlet 205 approaching the temperature of the secondary side inlet 204, a deeper heat exchange depth can be achieved to meet the complex working conditions with small temperature difference or small approximation requirements.

[0078] In other examples of embodiments of this application, the primary side inlet 203 may be located below the inlet side 201, the secondary side inlet 204 may be located above the inlet side 201, the primary side outlet 205 may be located above the outlet side 202, and the secondary side outlet 206 may be located below the outlet side 202, 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 2.

[0079] Continue as Figure 4 and Figure 5 As shown, the primary side liquid inlet 203 and the primary side liquid outlet 205 are located near the first frame 101 (not shown in this figure), and the secondary side liquid inlet 204 and the secondary side liquid outlet 206 are located near the second frame 102 (not shown in this figure), so that the orthographic projections of the primary side liquid inlet 203, the secondary side liquid inlet 204, the primary side liquid outlet 205 and the secondary side liquid outlet 206 on the heat exchanger 2 do not overlap.

[0080] This layout spatially separates and staggers the projections of the four ports of heat exchanger 2, reducing the risk of thermal short circuits and preventing heat exchange between high-temperature inlet and low-temperature outlet liquids or vice versa before sufficient heat exchange occurs, thereby improving overall heat exchange efficiency. Simultaneously, the dispersed arrangement of the four ports fully utilizes the space on both sides of heat exchanger 2, providing independent connection areas for each pipeline, avoiding pipeline crossings and collisions, thus facilitating installation, disassembly, and subsequent maintenance. It also optimizes overall compactness, reduces the risk of pipeline interference, and improves system maintainability and space utilization.

[0081] In other examples of embodiments of this application, the primary side inlet 203 and the primary side outlet 205 may be disposed near the second frame 102 (not shown in this figure), and the secondary side inlet 204 and the secondary side outlet 206 may be disposed near the first frame 101 (not shown in this figure), so that the orthographic projections of the primary side inlet 203, the secondary side inlet 204, the primary side outlet 205 and the secondary side outlet 206 on the heat exchanger 2 do not overlap.

[0082] In some other examples of embodiments of this application, the orthographic projections of the primary side inlet 203 and the primary side outlet 205 on the heat exchanger 2 may overlap, as may the orthographic projections of the secondary side inlet 204 and the secondary side outlet 206 on the heat exchanger 2. This arrangement allows the first and second coolants to flow laterally in the horizontal direction within the plates, resulting in shorter paths and fewer turns, thereby reducing flow resistance and pressure drop. Simultaneously, the internal flow channels are symmetrically distributed, allowing the first and second coolants to enter each plate channel evenly, reducing flow deviation and thus improving heat exchange efficiency and delaying localized scaling.

[0083] In this embodiment of the application, the distance between the first frame 101 and the heat exchanger 2 along the second direction b is greater than the distance between the heat exchanger 2 and the second frame 102.

[0084] In this embodiment, the heat exchanger 2 has passed factory inspection and requires less maintenance during use, while the replenishment tank, power supply unit, and circulation pump require frequent maintenance and repair. Therefore, along the first direction a, the heat exchanger 2 is closer to the second frame 102 than the first frame 101. On the one hand, this allows for single-sided maintenance of the cooling distribution device 100, meaning maintenance can be performed solely through the maintenance port, eliminating the need to reserve maintenance space behind the second frame 102 when arranging the cooling distribution device 100, thus reducing the space occupied by the cooling distribution device 100 in the data center. On the other hand, placing the frequently maintained replenishment tank, power supply unit, and circulation pump near the maintenance port also reduces maintenance difficulty, freeing maintenance personnel from entering the cabinet 1 or performing maintenance around multiple sides of the cooling distribution device 100. In addition, since it is necessary to reserve corresponding maintenance space for the replenishment tank, power supply device and circulation pump, they are placed in a position close to the maintenance port, and the heat exchanger 2 is placed in a position far away from the maintenance port. This allows the replenishment tank, power supply device and circulation pump to share the maintenance space, thereby optimizing the spatial layout of cabinet 1 and improving the space utilization of cabinet 1.

[0085] Based on the above layout, when the aforementioned components are damaged, maintenance only needs to be performed on one side of the first frame 101 of cabinet 1. Therefore, the second frame 102 can be placed against the wall within the equipment room, while the third frame 103 and the fourth frame 104 are arranged adjacent to the fourth frame 104 or the third frame 103 of the adjacent device, achieving a close, side-by-side arrangement of the two cooling distribution devices 100. This layout saves floor space, increases cabinet utilization, and allows for the deployment of a larger number of cooling distribution devices 100 within a limited space, providing greater flow and cooling capacity, and supporting higher power density liquid-cooled data centers.

[0086] Return to Figure 2 As shown, the cooling capacity distribution device 100 further includes: a primary side liquid inlet pipe 301, a secondary side liquid inlet pipe 302, a primary side liquid outlet pipe 303, and a secondary side liquid outlet pipe 304. The heat exchanger 2 uses the primary side liquid inlet pipe 301, the secondary side liquid inlet pipe 302, the primary side liquid outlet pipe 303, and the secondary side liquid outlet pipe 304 to exchange the heat generated by the second coolant in the cold plate 510 of the liquid-cooled server 500.

[0087] One end of the primary side liquid inlet pipe 301 is connected to the primary side liquid inlet 203 (not shown in this figure) of the heat exchanger 2, and the other end is connected to the primary side inlet 1071. One end of the secondary side liquid inlet pipe 302 is connected to the secondary side liquid inlet 204 (not shown in this figure) of the heat exchanger 2, and the other end is connected to the secondary side inlet 1072. One end of the primary side liquid outlet pipe 303 is connected to the primary side liquid outlet 205 (not shown in this figure) of the heat exchanger 2, and the other end is connected to the primary side outlet 1081. One end of the secondary side liquid outlet pipe 304 is connected to the secondary side liquid outlet 206 (not shown in this figure) of the heat exchanger 2, and the other end is connected to the secondary side outlet 1082.

[0088] Figure 6 An exemplary rear view of a cooling capacity distribution device provided in an embodiment of this application is shown, wherein, for clarity of illustration, Figure 6 The second frame 102 is hidden in the middle. In this example, along the first direction a, there is a first gap A between the liquid inlet side 201 of the heat exchanger 2 and the cabinet 1, and a second gap B between the liquid outlet side 202 and the cabinet 1. That is, the heat exchanger 2 is set in the middle of the cabinet 1 along the first direction a, and the size of the heat exchanger 2 along the first direction a is smaller than the size of the heat exchanger 2 along the third direction c.

[0089] The heat exchanger 2 in this application is relatively large in both weight and size. Positioning it centrally within the cabinet 1 lowers the device's center of gravity, preventing tipping during transport or movement and improving the device's transport stability and operational safety. Simultaneously, making the dimension of the heat exchanger 2 along the first direction a smaller than its dimension along the third direction c minimizes the space occupied by the heat exchanger 2 in the first direction a. This provides ample space for the subsequent arrangement of inlet and outlet pipes on both sides of the heat exchanger 2, facilitating their connection and maintenance, and thus improving the overall structural compactness and operability.

[0090] The primary side liquid inlet 203, secondary side liquid inlet 204, primary side liquid outlet 205 and secondary side liquid outlet 206 of the heat exchanger 2 inside the existing cold energy distribution device 100 are arranged on the same side of the heat exchanger 2, so that the primary side liquid inlet pipe 301, secondary side liquid inlet pipe 302, primary side liquid outlet pipe 303 and secondary side liquid outlet pipe 304 connected thereto are also concentrated on the same side of the heat exchanger 2.

[0091] This layout brings the four pipelines together in the same area, making them prone to mutual interference and spatial obstruction, and making straight-line laying impossible. Pipes must be routed by staggering layers, adding bends, or extending horizontal sections to avoid these obstacles, thus occupying a significant amount of installation space.

[0092] Due to limitations in the piping layout, the available installation space for heat exchanger 2 is compressed, making it difficult to replace it with a heat exchanger 2 that has a stronger heat exchange capacity. At the same time, the space for other functional components is also squeezed, requiring both front and rear doors to be opened for maintenance operations. This results in a large footprint for the cooling distribution unit in the equipment room, limiting the number that can be deployed and restricting the overall computing power and cooling capacity allocation efficiency.

[0093] Therefore, such as Figure 6 As shown, the first gap A is used to accommodate the primary side liquid inlet pipe 301 and the secondary side liquid inlet pipe 302, and the second gap B is used to accommodate the primary side liquid outlet pipe 303 and the secondary side liquid outlet pipe 304.

[0094] In this embodiment, the heat exchanger 2 is placed in the center of the cabinet 1. A primary-side liquid inlet pipe 301 and a secondary-side liquid inlet pipe 302 are connected to one side of the heat exchanger 2 along the first direction a, and a primary-side liquid outlet pipe 303 and a secondary-side liquid outlet pipe 304 are connected to the other side of the heat exchanger 2 along the first direction a. On the one hand, this allows for better utilization of the space in the cabinet 1 along the first direction a, enabling the heat exchanger 2 and its connected pipes to be evenly distributed within the cabinet 1. On the other hand, it avoids crossing and interference between the liquid inlet and liquid outlet pipes, thus eliminating the need to extend the pipe length or occupy additional space due to avoidance. Furthermore, it facilitates the partitioned installation of the liquid inlet and liquid outlet pipes, making maintenance work simpler and more convenient for installers.

[0095] Saving space occupied by piping frees up more installation space for heat exchanger 2, thereby improving its scalability. Heat exchanger 2 can be flexibly adjusted in size according to actual operating conditions; for example, a larger heat exchanger 2 with higher heat exchange capacity can be installed, thus accommodating larger flow rates and cooling capacities. This significantly improves the expandability of the cooling capacity distribution device 100, meeting requirements for a wide range of cooling capacities, secondary side supply and return liquid temperature differences, and primary and secondary side proximity. Furthermore, the reduced space occupied by piping allows for the placement of other functional components, enabling cabinet 1 to perform maintenance operations with only a single maintenance port on the first frame 101.

[0096] The above structural design can reduce the overall size of the cooling capacity distribution device 100, thereby reducing the floor space required. This allows for the deployment of a larger number of cooling capacity distribution devices 100 within the equipment room, or the configuration of a heat exchanger 2 with a stronger heat exchange capacity while maintaining the same floor space. Both methods can achieve a larger total heat exchange, thereby improving the overall efficiency of the configuration between computing power and cooling capacity.

[0097] Return to Figure 2 As shown, two inlets 107 and two outlets 108 are respectively located on both sides of the heat exchanger 2 along the first direction a, with the two inlets 107 located near the fourth frame 104 and the two outlets 108 located near the third frame 103. Based on this, the primary side liquid inlet pipe 301 and the secondary side liquid inlet pipe 302 are generally arranged on one side of the heat exchanger 2, while the primary side liquid outlet pipe 303 and the secondary side liquid outlet pipe 304 are generally arranged on the other side of the heat exchanger 2. This arrangement avoids crossing and interference between the four pipes, and also prevents interference between the pipes, the two inlets 107, and the two outlets 108 and other components inside the cabinet 1.

[0098] Meanwhile, since the two inlets 107 are located close to the primary side inlet pipe 301 and the secondary side inlet pipe 302, and the two outlets 108 are located close to the primary side outlet pipe 303 and the secondary side outlet pipe 304, the length of the four pipes can be shortened, reducing space occupation and facilitating pipe connection. In addition, this layout makes the connection between the inlet pipe and the inlet 107, and between the outlet pipe and the outlet 108, easy to maintain.

[0099] In this embodiment, the cabinet 1 is used to house two heat exchangers 2.

[0100] Continue as Figure 6 As shown, the two heat exchangers 2 are stacked along the third direction c. On the one hand, this can improve the heat exchange capacity of the cold energy distribution device 100. On the other hand, it can make full use of the space in the third direction c, thereby reserving sufficient space in the first direction a for the primary side liquid inlet pipe 301, the secondary side liquid inlet pipe 302, the primary side liquid outlet pipe 303, and the secondary side liquid outlet pipe 304, thus improving space utilization.

[0101] In some examples of embodiments of this application, the four ports of the two heat exchangers 2 are in the same position, so that the connection method between the two heat exchangers 2 and the pipeline is consistent. This not only facilitates the unified design and mass prefabrication of pipelines, simplifies the overall pipeline layout, reduces connection complexity, and reduces the risk of incorrect pipeline connection, but also helps to reduce the types of spare parts, improve assembly efficiency, and enhance the reliability of the system.

[0102] In other examples of embodiments of this application, the positions of the four ports of the heat exchanger 2 can be flexibly adjusted according to the actual layout of multiple components inside the cabinet 1, optimizing the pipeline layout from a global perspective, making the pipeline route more reasonable, avoiding interference with other components, and improving space utilization.

[0103] Typically, each of the two heat exchangers 2 requires four complete primary-side liquid inlet pipes 301, secondary-side liquid inlet pipes 302, primary-side liquid outlet pipes 303, and secondary-side liquid outlet pipes 304, totaling eight pipes. However, in addition to the multiple pipes, the cabinet 1 also houses several large components such as filters, expansion tanks, and circulating pumps along both sides of the first direction a, occupying a significant amount of space. This results in insufficient remaining space on both sides of the cabinet 1 to accommodate such a dense pipe arrangement, leading to a severe shortage of pipe layout space. If the conventional arrangement is forced, the overall volume of the cabinet 1 must be increased, thereby increasing the floor space, which is detrimental to the miniaturization and integration design of the device.

[0104] Therefore, in some examples of embodiments of this application, four pipelines are connected in parallel to two heat exchangers 2 by first splitting the flow and then merging it, thereby reducing the number and length of pipelines and making the pipeline layout more reasonable. The following describes this parallel connection method.

[0105] For example, the primary side liquid inlet pipe 301 is used to connect the primary side liquid inlets 203 of the two heat exchangers 2, the secondary side liquid inlet pipe 302 is used to connect the secondary side liquid inlets 204 of the two heat exchangers 2, the primary side liquid outlet pipe 303 is used to connect the primary side liquid outlets 205 of the two heat exchangers 2, and the secondary side liquid outlet pipe 304 is used to connect the secondary side liquid outlets 206 of the two heat exchangers 2.

[0106] This application splits the primary-side liquid inlet pipe 301, secondary-side liquid inlet pipe 302, primary-side liquid outlet pipe 303, and secondary-side liquid outlet pipe 304 on both sides near the two heat exchangers 2. This allows a single pipe to simultaneously connect to the corresponding interfaces of both heat exchangers 2, thereby eliminating the need for additional pipe length in the confluence section, shortening the overall pipe length, reducing the space occupied by the pipes within the cabinet 1, and resulting in a more compact and rational layout. The saved space can be used to increase the size of the heat exchangers 2, thereby improving heat exchange capacity and efficiency.

[0107] Figure 7 This illustration shows a partial structural diagram of a cooling capacity distribution device provided in an embodiment of this application from a first angle. Figure 8 The illustration shows a partial structural diagram of a cooling capacity distribution device provided in an embodiment of this application from a second angle. The diagram is provided for clarity. Figure 7 and Figure 8 The device conceals multiple components, including cabinet 1, filter, replenishment tank, power supply unit, and expansion tank. Both the first and second angles are viewing directions from the second frame 102 of the cold energy distribution device 100 towards the first frame 101. The first angle emphasizes the primary-side liquid inlet pipe 301 and the secondary-side liquid inlet pipe 302, while the second angle emphasizes the primary-side liquid outlet pipe 303 and the secondary-side liquid outlet pipe 304. In this example, each of the primary-side liquid inlet pipe 301, secondary-side liquid inlet pipe 302, primary-side liquid outlet pipe 303, and secondary-side liquid outlet pipe 304 includes two third pipes 305 and one fourth pipe 306. The two third pipes 305 are respectively connected to two heat exchangers 2 and are also connected to one fourth pipe 306. The fourth pipe 306 is connected to the inlet 107 or outlet 108 (not shown in this figure) of cabinet 1.

[0108] This application addresses the issue by first splitting the flow between two heat exchangers 2 using two third pipes 305 and then converging it using a fourth pipe 306. This reduces the number of pipes required for the converging section to only one fourth pipe 306, effectively halving the number of pipes compared to conventional solutions. This arrangement shortens the overall pipe length and reduces the number of pipes, thereby decreasing the types of spare parts and installation complexity. It also reduces the space occupied by the pipes, resulting in a more rational layout. The saved space can provide leeway for increasing the size of the heat exchangers 2, ultimately contributing to improved heat exchange capacity and efficiency.

[0109] The two heat exchangers 2 are connected in parallel by two third pipes 305 and one fourth pipe 306, so that the first coolant and the second coolant can flow through the two heat exchangers 2 at the same time. The total flow cross-sectional area is increased, thereby reducing the flow pressure drop of the first coolant and the second coolant through each heat exchanger 2, reducing power loss and improving system energy efficiency.

[0110] Meanwhile, the parallel structure allows the two heat exchangers 2 to serve as backups for each other under partial load or fault conditions. That is, when one heat exchanger 2 requires maintenance or fails, the other can still maintain basic cooling capacity distribution functions, avoiding system downtime and thus enhancing the system's operational reliability. Moreover, the parallel configuration also facilitates flexible adjustment of the number of heat exchangers 2 in operation according to load changes, improving the system's adaptability and scalability.

[0111] In other examples of embodiments of this application, the two heat exchangers 2 can also be connected in series. Specifically, the primary side inlet pipe 301 is connected to the primary side inlet 203 of one heat exchanger 2, and the primary side outlet 205 of that heat exchanger 2 is connected to the primary side inlet 203 of the other heat exchanger 2 via a pipe. The primary side outlet 205 of the other heat exchanger 2 is connected to the primary side outlet pipe 303. Similarly, the secondary side inlet pipe 302 is connected to the secondary side inlet 204 of one heat exchanger 2, and the secondary side outlet 206 of that heat exchanger 2 is connected to the secondary side inlet 204 of the other heat exchanger 2 via a pipe. The secondary side outlet 206 of the other heat exchanger 2 is connected to the secondary side outlet pipe 304. The above series connection method can also shorten the overall length of the pipeline.

[0112] As server chip power consumption continues to rise, when the heat exchanger 2's heat exchange capacity is insufficient, the heat exchange capacity is usually improved by increasing the number of plates in the heat exchanger 2 or by using a wider flow channel. This method can expand the heat exchange area and lengthen the heat exchange path, thereby meeting the heat dissipation requirements of higher power chips, but it also increases the thickness of the heat exchanger 2. Therefore, on-site, it is necessary to replace it with a heat exchanger 2 of appropriate thickness according to different heat exchange capacity requirements.

[0113] Because heat exchangers 2 of different thicknesses differ in interface locations and overall structural dimensions, it is often necessary to replace the inlet and outlet liquid pipelines connected to them simultaneously to adapt to the new interface layout and pipeline length requirements. This not only wastes materials from the original pipelines and increases the types and maintenance costs of spare pipelines, but also makes the replacement operation complex and cumbersome, prolongs maintenance time, and adversely affects the system's operation and maintenance efficiency and availability.

[0114] This application optimizes the pipeline layout so that the pipeline and heat exchanger 2 do not interfere with each other during the replacement process. Only a portion of the pipeline needs to be removed to complete the disassembly and assembly of the heat exchanger 2, thereby reducing replacement costs, shortening maintenance time, and enabling rapid replacement of the heat exchanger 2. The method of removing the portion of the pipeline is described below.

[0115] Continue as Figure 7 and Figure 8 As shown, each third pipe 305 includes a third section 3051 and a fourth section 3052. The third section 3051 is connected to the heat exchanger 2, and one end of the fourth section 3052 is connected to the third section 3051, while the other end is connected to the fourth pipe 306.

[0116] Among them, the third segment 3051 extends along the first direction a, and the fourth segment 3052 extends along the third direction c, so that the two third pipes 305 corresponding to the same interface of the two heat exchangers 2 together form a C shape.

[0117] In this embodiment, the third segment 3051 is detachably connected to both the heat exchanger 2 and the fourth segment 3052. This facilitates the independent assembly and disassembly of the heat exchanger 2, which is beneficial for future maintenance or replacement.

[0118] In this application, the third section 3051 is detachably connected to the heat exchanger 2, and also detachably connected to the fourth section 3052, allowing the third section 3051 to be disassembled independently. When it is necessary to replace the heat exchanger 2 with one of different heat exchange capacities, the dimensions of the heat exchanger 2 along the first direction a will change accordingly. In this case, only the connections between the third section 3051 and the heat exchanger 2, and between the third section 3051 and the fourth section 3052, need to be removed to separate the third section 3051 as a whole. Since the heat exchanger 2 is located close to the second frame 102, there is no need to remove other structures to make way, thus avoiding damage to surrounding components, reducing the impact of replacement operations on the overall structure, and improving the safety and convenience of the maintenance process.

[0119] Based on the dimensions of the replaced heat exchanger 2 along the first direction a, only the third section 3051 of the corresponding length needs to be replaced, while the fourth section 3052 does not need to be replaced, thus matching the four pipelines with the new heat exchanger 2. This reduces the types and number of parts that need to be replaced, lowering spare parts costs. It also simplifies the operation steps, shortens the replacement time, and enables rapid replacement of the heat exchanger 2, improving operation and maintenance efficiency and system availability. This structural design can accommodate different cooling capacity requirements, different supply and return liquid temperature differences, and different primary and secondary side proximity requirements, thereby adapting to a wider range of operating conditions.

[0120] In other examples of embodiments of this application, the third pipe 305 may be arranged at an angle inside the cabinet 1 so that it does not need to be bent, with one end detachably connected to the heat exchanger 2 and the other end directly detachably connected to the fourth pipe 306.

[0121] For example, in the third pipe 305 of the primary side liquid inlet pipe 301, the secondary side liquid inlet pipe 302, the primary side liquid outlet pipe 303 and the secondary side liquid outlet pipe 304, the third segment 3051 and the fourth segment 3052 both include a telescopic structure, and the telescopic structure can shrink and extend along the length of the first direction a or along the length of the third direction c.

[0122] This application provides a telescopic structure on the primary side liquid inlet pipe 301, the secondary side liquid inlet pipe 302, the primary side liquid outlet pipe 303, and the secondary side liquid outlet pipe 304. The telescopic structure can provide the necessary clearance space by telescoping when replacing the heat exchanger 2, which facilitates the connection or separation of the pipes and the corresponding interfaces of the heat exchanger 2 without having to completely disassemble other fixed pipes.

[0123] like Figure 7 and Figure 8 As shown, a retractable structure is provided on the third segment 3051 for retracting along the first direction a, and on the fourth segment 3052 for retracting along the third direction c.

[0124] Meanwhile, the telescopic structure can compensate for the processing tolerances and assembly errors of the interfaces and pipelines of heat exchanger 2, avoiding interference or poor sealing at the connection points during disassembly and assembly due to rigid connections. In addition, the length of the telescopic structure can be flexibly adjusted according to the dimensions of heat exchanger 2 along the first direction a or the third direction c, thereby adapting to heat exchangers 2 with different heat exchange capacities, meeting actual operating conditions, and improving product compatibility.

[0125] It is understood that the location and number of retractable structures are not limited to the aforementioned embodiments. Retractable structures can be installed on any one or more of the primary side inlet pipe 301, secondary side inlet pipe 302, primary side outlet pipe 303, and secondary side outlet pipe 304, and one or more retractable structures can be installed on each pipe. Each retractable structure can be installed only on the third segment 3051 of the corresponding pipe, or only on the fourth segment 3052, or simultaneously on both the third segment 3051 and the fourth segment 3052, and the number installed on each segment can also be one or more; this application does not impose any limitations on these aspects.

[0126] Furthermore, with the dimension of the cabinet 1 along the first direction a fixed value, the sum of the thickness of the heat exchanger 2 and the length of the third section 3051 on both sides of the heat exchanger 2 is also a fixed value. In this application, by providing a telescopic structure on the third section 3051, the telescopic amount of the telescopic structure can be adjusted to accommodate heat exchangers 2 of different thicknesses, thereby allowing the replacement of heat exchangers 2 with different heat exchange capacities according to actual operating conditions without the need for a complete replacement of the piping.

[0127] Therefore, when the thickness variation of the heat exchanger 2 that needs to be replaced is within the adjustment range of the expandable structure of the third section 3051, the replacement can be completed simply by adjusting the expansion and contraction of the expandable structure. When the thickness variation exceeds this adjustment range, the replacement can be completed by removing the third section 2051.

[0128] The retractable structure is located on the third segment 3051 or the fourth segment 3052. The retractable structure can be the entire third segment 3051 or the fourth segment 3052, or it can be a part of the third segment 3051 or the fourth segment 3052, meaning the length of the retractable structure is less than the length of the third segment 3051 or the fourth segment 3052.

[0129] Figure 9 The illustration shows a partial structural diagram of a cooling capacity distribution device from a third angle, provided in an embodiment of this application. The diagram is provided for clarity. Figure 9 The device conceals multiple components, including a cabinet, filter, replenishment tank, power supply unit, and expansion tank. The third angle is the viewing direction from the first frame 101 of the cold energy distribution device 100 towards the second frame 102, and it focuses on showing the fourth pipe 306. In this example, each fourth pipe 306 includes a fifth segment 3061 and a sixth segment 3062. The fifth segment 3061 is connected to the third pipe 305, and one end of the sixth segment 3062 is connected to the fifth segment 3061, while the other end is connected to the inlet 107 or outlet 108 (not shown in this figure) of the cabinet 1.

[0130] Among them, the fifth segment 3061 extends along the second direction b, and the sixth segment 3062 extends along the third direction c.

[0131] Based on the above layout, one end of the primary side liquid inlet pipe 301, the secondary side liquid inlet pipe 302, the primary side liquid outlet pipe 303, and the secondary side liquid outlet pipe 304 are connected to the heat exchanger 2 near the second frame 102, and the other end is connected to the two inlets 107 and the two outlets 108 near the first frame 101. This allows the four pipes to pass through the opening in the cabinet 1 from one side of the first frame 101, enabling connection to the external cold source 300 and the liquid-cooled server 500. This layout not only facilitates centralized pipe installation but also makes subsequent inspection and maintenance easier.

[0132] In this embodiment, the fifth segment 3061 of the primary side outlet pipe 303 is configured as a U-shaped structure. This U-shaped structure has two side arms and an arc-shaped connecting portion. Two fourth segments 3052 are respectively connected to the middle regions of the two side arms, and the ends of both side arms are sealed to the sixth segment 3062. Each side arm is independently equipped with a control valve, which is used to regulate the flow rate of the first coolant.

[0133] When the control valve inside one of the side arms fails to open properly due to sealing failure or drive malfunction, the first coolant flowing out of the two heat exchangers 2 can continue to flow through the other side arm, thus forming a complete flow path. Through the aforementioned U-shaped structure, bypass and backup functions of the two branches can be achieved. Without the need for additional bypass piping, the total cooling flow can be maintained uninterrupted even if a valve on one side fails, thereby ensuring the fault tolerance and continuous operational reliability of the cooling system.

[0134] Figure 10 This example illustrates a schematic diagram of two heat exchangers and a secondary side liquid inlet pipe provided in an embodiment of this application. In this example, heat exchanger 2 is arranged at an angle relative to a third direction c, such that at least one of the primary side liquid inlet 203, secondary side liquid inlet 204, primary side liquid outlet 205, and secondary side liquid outlet 206 of heat exchanger 2 is located at the lowest point of the entire heat exchanger 2. This allows gravity to be used as an active drain outlet, enabling residual pure water inside heat exchanger 2 to be discharged automatically under gravity. Compared to a vertically arranged heat exchanger 2, this inclined draining method reduces the amount of residual liquid inside the heat exchanger 2, thereby significantly shortening the subsequent drying time, improving drying efficiency, and also helping to reduce the risk of bacterial growth due to long-term liquid accumulation.

[0135] like Figure 10 As shown, the tops of the two heat exchangers 2 are inclined toward the second frame 102 (not shown in this figure), so that the secondary side liquid inlet 204 is the lowest of the four ports of the heat exchanger 2.

[0136] In some other examples of embodiments of this application, when the second coolant flows in a top-in, bottom-out manner inside the heat exchanger 2, the tops of the two heat exchangers 2 are tilted toward the second frame 102, so that the secondary side outlet 206 is the lowest of the four ports of the heat exchanger 2.

[0137] In some other examples of embodiments of this application, when the secondary side inlet 204 and the secondary side outlet 206 are set close to the fourth frame 104, the tops of the two heat exchangers 2 are inclined toward the first frame 101, so that the secondary side inlet 204 or the secondary side outlet 206 becomes the lowest of the four interfaces of the heat exchanger 2.

[0138] Understandably, when the positions of the four ports of the two heat exchangers 2 do not correspond, the tilt direction of each heat exchanger 2 can be selected according to the requirements for residual liquid discharge. For example, the top of one heat exchanger 2 can be tilted towards the first frame 101, while the top of the other heat exchanger 2 can be tilted towards the second frame 102.

[0139] Furthermore, it is not limited to using the secondary side inlet 204 as the lowest interface. Instead, any one of the primary side inlet 203, secondary side inlet 204, primary side outlet 205, and secondary side outlet 206 can be selected as the lowest interface of the heat exchanger 2 according to the requirement of draining residual liquid in the first or second coolant.

[0140] This application embodiment does not restrict the tilt direction of the heat exchanger 2, nor does it restrict the arrangement position of the four ports on the heat exchanger 2: along the third direction c, the primary side inlet 203 and the secondary side outlet 206 are higher than the secondary side inlet 204 and the primary side outlet 205, and one of the secondary side inlet 204 and the primary side outlet 205 is lower than the other of the secondary side inlet 204 and the primary side outlet 205. Alternatively, along the third direction c, the secondary side inlet 204 and the primary side outlet 205 are higher than the primary side inlet 203 and the secondary side outlet 206, and one of the primary side inlet 203 and the secondary side outlet 206 is lower than the other of the primary side inlet 203 and the secondary side outlet 206.

[0141] The tilt angle of heat exchanger 2 needs to balance the discharge effect of residual liquid with the stability of the overall structure. If the tilt angle is too small, the flow of residual liquid inside heat exchanger 2 will be insignificant, making it difficult to effectively discharge the residual liquid, which may lead to corrosion or a decrease in heat exchange efficiency after long-term use. If the tilt angle is too large, due to the large weight of heat exchanger 2, the center of gravity shift will increase, making it prone to tipping over. At the same time, it will increase the difficulty and cost of fixing the structure, and the structural strength requirements of the frame will also be correspondingly increased. Therefore, in this embodiment, the tilt angle of heat exchanger 2 relative to the third direction c is 5°-10°.

[0142] In this embodiment, the tilt angle of the heat exchanger 2 is controlled within the range of 5° to 10°, which can simultaneously meet the requirements of residual liquid discharge effect and overall structural stability.

[0143] Continue as Figure 10 As shown, a drain port 307 is provided on the secondary side liquid inlet pipe 302 connected to the secondary side liquid inlet 204. The drain port 307 is located on the third section 3051 and is used to drain the accumulated liquid inside the heat exchanger 2.

[0144] This application provides a drain port 307 on the inlet or outlet pipe connected to the interface located at the lowest point of the heat exchanger 2. This allows residual liquid inside the heat exchanger 2 to be drained through the drain port 307 without disconnecting the pipe from the heat exchanger 2. Compared to methods requiring pipe removal, this design improves the convenience and efficiency of the draining operation, avoids the risk of seal failure, pipe damage, or leakage caused by frequent disassembly and assembly, and reduces the impact of maintenance operations on normal system operation, minimizing maintenance downtime.

[0145] Understandably, based on the location of the four ports on heat exchanger 2, the drain port 307 only needs to be located on the primary side inlet pipe 301, secondary side inlet pipe 302, primary side outlet pipe 303 or secondary side outlet pipe 304 connected to the lowest port among the primary side inlet port 203, secondary side inlet port 204, primary side outlet port 205 and secondary side outlet port 206.

[0146] like Figure 10 As shown, the fourth section 3052 corresponding to the upper heat exchanger 2 and the fourth section 3052 corresponding to the lower heat exchanger 2 both extend along the third direction c, so that the drain port 307 can be provided only on the third section 3051 corresponding to the lower heat exchanger 2. The residual liquid inside the upper heat exchanger 2 flows sequentially through the upper third section 3051, the fourth section 3052, the lower fourth section 3052, and the third section 3051, and is finally discharged from the pipeline through the drain port 307.

[0147] Figure 11 An exemplary schematic diagram of two heat exchangers and multiple support members provided in an embodiment of this application is shown. In this example, the two heat exchangers 2 are stacked along a third direction c and are inclined along the third direction c. To provide stable fixed support for the two heat exchangers 2, the cabinet 1 is used to accommodate the first support member 401.

[0148] The first support member 401 is fixed to the top of the cabinet 1 (not shown in this figure), and the first support member 401 is located on both sides of the heat exchanger 2 along the first direction a to clamp the heat exchanger 2.

[0149] In this embodiment, the first support member 401 is fixed by the top of the cabinet 1, thereby defining its position, and clamping and constraining the stacked and inclined heat exchangers 2 from both sides of the heat exchanger 2, thereby achieving stable support for the heat exchanger 2, preventing the heat exchanger 2 from overturning during use or transportation, and avoiding insufficient operational stability due to vibration or fluid pulsation.

[0150] Based on this, the first support member 401 also laterally fixes the two heat exchangers 2, thereby effectively controlling the machining tolerance of the heat exchangers 2 and the cumulative error generated during the assembly process within a preset controllable range, thus avoiding interference with other components due to improper installation of the heat exchangers 2, or failure to install them tightly with the inlet and outlet liquid pipelines.

[0151] The first support member 401 includes two members arranged opposite each other along the first direction a, and the two first support members 401 are respectively located on both sides of the two heat exchangers 2 along the thickness direction. The two heat exchangers 2 are both located in the space between the two third support members 403, and each heat exchanger 2 is fixedly connected to the first support members 401 on both sides.

[0152] like Figure 11 As shown, a sixth support member 402 is also provided on the top of the cabinet 1. The sixth support member 402 extends along the first direction a. The two ends of the sixth support member 402 are fixedly connected to the third frame 103 (not shown in this figure) and the fourth frame 104 (not shown in this figure) respectively. The middle area of ​​the sixth support member 402 is fixedly connected to the top of the two first support members 401 to realize the fixed connection between the first support members 401 and the top of the cabinet 1.

[0153] like Figure 11 As shown, the cabinet 1 is also used to accommodate a third support member 403, which is used to fix and support the heat exchanger 2 and the first support member 401.

[0154] The third support member 403 is located between the bottom of the heat exchanger 2 and the cabinet 1 along the third direction c, so that there is a certain space between the third support member 403 and the bottom of the cabinet 1. This space can be used for the subsequent arrangement of the circulating pump, so as to ensure the stability of the support while taking into account the space utilization and assembly convenience of the internal structure.

[0155] like Figure 11As shown, the third support member 403 includes multiple first parts 4031 and one second part 4032. The multiple first parts 4031 are fixedly connected to the bottom of the cabinet 1 (not shown in this figure) and extend along the third direction c. By selecting first parts 4031 of different lengths or by using a telescopic sleeve structure for the first parts 4031, the heat exchanger 2 can be raised to a preset height according to actual usage requirements, thereby raising the heat exchanger 2 to a specified height. This lifting structure creates a certain height of empty area below the heat exchanger 2, providing sufficient space for subsequent placement of a circulating pump in this area.

[0156] In this embodiment, two first portions 4031 are arranged side by side along the first direction a. To further improve structural stability, multiple first portions 4031 may be arranged along different directions, and transverse connectors or cross braces may be provided between adjacent first portions 4031 to form a frame-type or truss-type support system.

[0157] like Figure 11 As shown, the second part 4032 extends in a direction perpendicular to the third direction c, i.e., it is set horizontally. The two sides of the second part 4032 are fixedly connected to the third frame 103 and the fourth frame 104 respectively, and the second part 4032 is fixedly connected to the first part 4031. Together, they constitute a support structure for the heat exchanger 2. In this embodiment, by setting the second part 4032 to extend horizontally and simultaneously fixing it to the third frame 103 and the fourth frame 104, a flat supporting plane is formed on its upper surface, allowing direct placement of the bottom of the heat exchanger 2 or the first support member 401, thereby achieving more stable and reliable support.

[0158] In other examples of embodiments of this application, when it is not necessary to raise the heat exchanger 2 to a preset height, the third support member 403 can be omitted, and only two first support members 401 are provided. In this case, the two first support members 401 are directly fixedly connected to the bottom of the cabinet 1, and diagonal braces are provided to prevent the first support members 401 from tilting.

[0159] In some other examples of embodiments of this application, the first support member 401 may not be provided. Instead, the second part 4032 of the third support member 403 may be set to be inclined relative to the horizontal plane, so that its inclination angle is consistent with the inclination angle required by the heat exchanger 2. Then, the bottom of the heat exchanger 2 may be directly fixedly connected to the inclined second part 4032.

[0160] To achieve the tilting of the second part 4032, various adjustment or connection structures can be adopted. For example, an adjustable screw can be set below one end of the second part 4032, and the support height can be changed by rotating the screw. Alternatively, pads of different thicknesses can be used at the connection between the second part 4032 and the first part 4031 to achieve the tilting of the second part 4032.

[0161] In some other examples of embodiments of this application, the bottom support structure of the heat exchanger 2 can also be fixedly supported by a hydraulic or pneumatic mechanism such as an external hydraulic tooling, so that the heat exchanger 2 tilts only when drainage is required and remains vertical when drainage is not required.

[0162] Figure 12 This application provides a schematic diagram of a structure comprising two heat exchangers, four inlet and outlet liquid pipelines, and multiple supporting components, as shown in the embodiment. For clarity, the following details are provided. Figure 12 The panels that make up the second frame 102 are hidden inside. It can be understood that the first frame 101, the second frame 102, the third frame 103, the fourth frame 104, the fifth frame 105 and the sixth frame 106 of the cabinet 1 are all composed of a grid-like frame support structure and panels.

[0163] In this example, the second frame 102 is used to accommodate the fifth support member 404, which is fixed to the top and bottom of the cabinet 1 respectively. Along the second direction b, the orthographic projection of part of the fifth support member 404 is located within the outline of the heat exchanger 2. By fixing the fifth support member 404 to the top and bottom of the cabinet 1 respectively, this application improves the structural strength of the second frame 102 and enables the fifth support member 404 or the second frame 102 as a whole to provide a blocking effect when the heat exchanger 2 overturns.

[0164] The orthographic projection of the other part of the fifth support member 404 lies within the contour range of the third support member 403, allowing the fifth support member 404 to also exert a limiting effect on the third support member 403 along the second direction b. Since the third support member 403 is fixed to the heat exchanger 2 through the first support member 401, this limiting effect can effectively constrain the displacement of the third support member 403. Thus, when the heat exchanger 2 is subjected to impact or vibration, energy is transferred through the first support member 401 to the fifth support member 404 for absorption and dispersion, further enhancing the buffering effect on the heat exchanger 2.

[0165] Continue as Figure 12As shown, the first support member 401 includes multiple through holes 4011. The primary side liquid outlet pipe 303 and the secondary side liquid outlet pipe 304 pass through part of the through holes 4011 and are fixed to the third frame 103. The primary side liquid inlet pipe 301 and the secondary side liquid inlet pipe 302 pass through another part of the through holes 4011 and are fixed to the fourth frame 104. This can prevent shaking in the middle area of ​​the pipes, thereby ensuring the connection reliability and operational stability of the entire liquid circuit system.

[0166] In this embodiment, the primary side liquid inlet pipe 301, secondary side liquid inlet pipe 302, primary side liquid outlet pipe 303, and secondary side liquid outlet pipe 304 are respectively clamped and fixed to the third frame 103 or the fourth frame 104 by connecting parts such as triangular reinforcing members, connecting steel plates, or clamps. For example, triangular reinforcing members or connecting steel plates can be used to connect the pipes and the frame, or clamps can be used to directly clamp the pipes to the frame beams, thereby ensuring reliable connection and easy assembly and disassembly.

[0167] Return to Figure 2 As shown, along the second direction b, the gap between the heat exchanger 2 and the first frame 101 (not shown in this figure) is used to accommodate the replenishment tank 5, which is used to replenish the heat exchanger 2 with a second coolant.

[0168] When the second coolant flows through the liquid-cooled server 500, its flow rate gradually decreases during operation. Therefore, in this embodiment, a replenishment tank 5 is installed on the secondary-side inlet pipe 302 or the secondary-side outlet pipe 304 to replenish the second coolant and maintain a stable flow rate. When the flow rate of the first coolant is insufficient, the replenishment tank 5 can also be used to replenish the first coolant in the heat exchanger 2.

[0169] In other examples of embodiments of this application, when the volume of the replenishment tank 5 is small, the replenishment tank 5 can also be set in the first gap A between the heat exchanger 2 and the first frame 101 or in the second gap B between the heat exchanger 2 and the second frame 102. No further restrictions are imposed here.

[0170] Figure 13 An exemplary structural diagram of a fluid replenishment tank and multiple supporting members provided in an embodiment of this application is shown. In this example, the cabinet 1 is used to house the second supporting member 405, which is used to fix the fluid replenishment tank 5. By fixing the fluid replenishment tank 5 with the second supporting member 405, this application can prevent the fluid replenishment tank 5 from shaking during use and improve structural stability.

[0171] like Figure 13As shown, the second support member 405 is fixed to the first support member 401. The second support member 405 is fixed to the first support member 401, and the two form an integral structure to fix the heat exchanger 2 and the replenishment tank 5 together. This can reduce the space occupied by the integral structure inside the cabinet 1, thereby making room for the arrangement of other components.

[0172] In this embodiment of the application, there are two second support members 405, both of which extend along the first direction a and are arranged vertically along the third direction c. Both second support members 405 are fixedly connected to the two first support members 401 and are located close to the first frame 101 (not shown in this figure).

[0173] The top of the replenishment tank 5 is bolted to the upper second support member 405, and the bottom of the replenishment tank 5 is bolted to the lower second support member 405, thus supporting the replenishment tank 5 between the two second support members 405. Furthermore, since the replenishment tank 5 is fixed to the first support member 401 via the second support member 405, and the replenishment tank 5 is entirely located above the second part 4032 of the third support member 403, both the replenishment tank 5 and the heat exchanger 2 are raised above the bottom of the cabinet 1. This creates a spacious area between the two and the sixth frame 106 of the cabinet 1. The height of this area is sufficient to accommodate the installation and maintenance of the circulating pump, thus achieving a compact arrangement of the circulating pump below the heat exchanger 2 and the replenishment tank 5.

[0174] Specifically, L-shaped reinforcing members 406 are provided at the top and bottom of the replenishment tank 5. One side of the L-shaped reinforcing member 406 is welded and fixed to the tank body of the replenishment tank 5, and the other side is attached to the second support member 405 and fixedly connected by bolts.

[0175] To further improve the stability of the connection between the replenishment tank 5 and the second support member 405, and to prevent relative displacement or torsional deformation of the two second support members 405 during vibration or transportation, a vertical connector 407 is also provided between the two second support members 405. The vertical connector 407 extends along a third direction c, and its upper and lower ends are fixedly connected to the two second support members 405 respectively. Through this vertical connector 407, the two second support members 405 and the first support member 401 form a closed rectangular or frame structure, which can enhance the overall rigidity and ensure that the replenishment tank 5 remains stable under various operating conditions.

[0176] Figure 14 The following is an exemplary structural diagram of a cabinet, heat exchanger, replenishment tank, power supply device, and multiple support components provided in an embodiment of this application. For clarity of illustration, the diagram is provided below. Figure 14The first frame 101 is hidden in the middle. In this example, along the second direction b, the replenishment tank 5 is located in the gap between the second support 405 and the first frame 101 (not shown in this figure), and the heat exchanger 2 is located in the gap between the second support 405 and the second frame 102.

[0177] Heat exchanger 2 is relatively large in size and weight, especially when it needs to be tilted or stacked in the third direction c. To ensure its stable placement within the cabinet 1, a support frame is required. Similarly, the replenishment tank 5, due to its large volume and weight of storing a significant amount of first or second coolant, also requires a support frame. This application addresses this by providing a second support member 405. This achieves dual support and fixation for both heat exchanger 2 and replenishment tank 5, simplifying the cabinet's support structure. Furthermore, the second support member 405 also partitions the cabinet space in the second direction b, placing heat exchanger 2 and replenishment tank 5 on opposite sides of the second support member 405. This makes the spatial arrangement of the cabinet 1 clearer and facilitates maintenance personnel's work.

[0178] In addition, the replenishment tank 5 is located in the gap between the heat exchanger 2 and the first frame 101, which does not occupy the pipeline layout space on both sides of the cabinet 1. The pipeline layout does not need to avoid the large replenishment tank 5, thereby further improving the rationality of the layout and the space utilization rate.

[0179] Return to Figure 2 As shown, along the second direction b, the gap between the heat exchanger 2 of the cabinet 1 and the first frame 101 (not shown in this figure) is used to accommodate the power supply device 6, which is used to supply power to the electrical equipment inside the cabinet 1.

[0180] In this embodiment of the application, the primary side liquid inlet pipe 301, the secondary side liquid inlet pipe 302, the primary side liquid outlet pipe 303, and the secondary side liquid outlet pipe 304 are equipped with multiple electrical devices such as sensors, and the power supply device 6 is used to supply power to the electrical devices such as sensors inside the cabinet 1.

[0181] Continue as Figure 2 As shown, the power supply device 6 is located in the gap between the heat exchanger 2 and the first frame 101, so the distance between the power supply device 6 and the primary side liquid inlet pipe 301, the secondary side liquid inlet pipe 302, the primary side liquid outlet pipe 303 and the secondary side liquid outlet pipe 304 is relatively short. Therefore, when making electrical connections with the electrical equipment on the pipes, the cable length is shortened, which can reduce line loss and wiring complexity.

[0182] In other examples of embodiments of this application, the power supply device 6 can also be located above the heat exchanger 2 and the replenishment tank 5 as a whole, or at the corner of the third frame 103 and the fifth frame 105, or at the corner of the fourth frame 104 and the fifth frame 105. It is only necessary to ensure that the power supply device 6 is located on the top layer of the entire cabinet 1; the specific location can be flexibly adjusted according to the wiring or piping layout.

[0183] In addition, along the third direction c, the gap between the liquid replenishment tank 5 and the top of the cabinet 1 is used to accommodate the power supply device 6, which can prevent leakage in the cold energy distribution device 100 from affecting the power supply device 6, thereby achieving the effect of water and electricity separation and improving the electrical safety of the whole machine.

[0184] Return to Figure 14 As shown, the cabinet 1 is also used to accommodate the fourth support member 408, which is used to accommodate the power supply device 6. By housing the power supply device 6 within the fourth support member 408, the housing of the fourth support member 408 can physically enclose and protect the power supply device 6.

[0185] The fourth support member 408 is fixed to the top of the cabinet 1. By fixing the fourth support member 408 to the top of the cabinet 1 and using the fourth support member 408 to house the power supply device 6, this application can prevent leakage from the cold energy distribution device 100 from affecting the power supply device 6, thereby achieving the effect of water and electricity separation and improving the electrical safety of the whole machine.

[0186] like Figure 14 As shown, the opening of the fourth support member 408 faces the maintenance port of the first frame 101 (not shown in this figure). The power supply device 6 is used to be pulled out or inserted into the fourth support member 408 along the second direction b under the action of external force. The power supply device 6 can be installed and removed in the fourth support member 408 along the second direction b, which facilitates flexible operation when connecting to an external power source. Moreover, when the internal circuit of the power supply device 6 fails, it can be quickly pulled out from the maintenance port along the second direction b without disassembling surrounding parts, making inspection and maintenance convenient.

[0187] Specifically, the power supply device 6 is installed in a retractable manner within the receiving cavity of the fourth support member 408. For example, a sliding connection can be achieved through the cooperation of a guide rail and a pulley. A guide rail is installed on the inner wall of the receiving cavity, and a pulley or ball-bearing slider adapted to the guide rail is provided on the corresponding side of the power supply device 6, thereby pushing or pulling the power supply device 6 into or out of the receiving cavity along the second direction b. Alternatively, both the inner wall of the receiving cavity and the outer wall of the power supply device are made of a material with a low coefficient of friction, making pulling easier.

[0188] Figure 15An exemplary schematic diagram of a structure of multiple support members provided in an embodiment of this application is shown. In this example, two seventh support members 409 are also provided between the second support member 405 and the fourth support member 408. One end of each seventh support member 409 is fixedly connected to the second support member 405, and the other end is fixedly connected to the fourth support member 408. Through the two vertically arranged seventh support members 409, reliable vertical support is achieved for the fourth support member 408, and the weight of the fourth support member 408 and its internal power supply device 6 (not shown in this figure) is transferred to the second support member 405 and the first support member 401 and the third support member 403 below it.

[0189] Meanwhile, the middle area of ​​the sixth support member 402 is also fixedly connected to the top of the fourth support member 408. Through the lateral arrangement of the sixth support member 402, the tops of the two first support members 401 can be connected into one unit, and lateral support can be provided to the fourth support member 408, limiting the displacement or swaying of the fourth support member 408 in the horizontal direction. Thus, together with the vertical seventh support member 409, it forms a multi-directional stable constraint on the fourth support member 408.

[0190] Return to Figure 6 As shown, the cabinet 1 houses the circulation pump 7, which drives the flow of the second coolant, providing circulation power for the second coolant flowing through the cold plate 510. This ensures that the second coolant flows continuously and stably between the cold plate 510 and the cooling capacity distribution device 100, forming a complete heat dissipation circulation loop. The stable driving force provided by the circulation pump 7 ensures that the flow rate and velocity of the second coolant meet the heat dissipation requirements, preventing localized overheating or uneven heat dissipation due to poor circulation, and further improving the heat dissipation efficiency and operational reliability of the liquid cooling system.

[0191] In this embodiment, the circulating pump 7 can increase its speed and flow rate by frequency conversion regulation, thereby enabling the cooling capacity distribution device 100 to be compatible with operating conditions with larger flow rates.

[0192] In this embodiment, the circulating pump 7 is installed on the secondary side outlet pipe 304 to deliver the second coolant to the secondary side outlet pipe 304. In other examples, the circulating pump 7 may also be installed on the secondary side inlet pipe 302 to receive the second coolant from the secondary side inlet pipe 302.

[0193] Continue as Figure 6 As shown, along the third direction c, the gap between the heat exchanger 2 and the bottom of the cabinet 1 is used to accommodate the circulating pump 7. By staggering the heat exchanger 2 and the circulating pump 7 along the third direction c, the overall layout is more compact, which can optimize the space utilization and thus save the floor space of the cooling distribution device 100.

[0194] Return to Figure 14As shown, the gap between the second part 4032 of the third support member 403 and the sixth frame 106 at the bottom of the cabinet 1 is used to accommodate the circulating pump 7, that is, the heat exchanger 2 and the circulating pump 7 are located on the upper and lower sides of the second part 4032, respectively. The second part 4032, as a support and isolation structure, can buffer the heat exchanger 2. When the heat exchanger 2 accidentally falls due to vibration or loose installation, the second part 4032 can prevent it from falling directly to the bottom of the cabinet 1, thereby avoiding hitting the circulating pump 7 located below and effectively protecting the circulating pump 7 from impact damage.

[0195] In this embodiment, the heat exchanger 2 is positioned above the circulating pump 7 along the third direction c. When the second coolant is pressurized by the circulating pump 7 below and delivered to the heat exchanger 2 above, its own gravity creates a downward static pressure in the pipeline during the upward transport process. This static pressure provides a stable back pressure at the secondary side inlet 204 of the heat exchanger 2, allowing the second coolant to fill the various plate channels inside the heat exchanger 2 evenly and stably. This reduces flow deviation or local air blockage caused by pressure fluctuations at the secondary side inlet 204, thereby improving heat exchange efficiency.

[0196] Furthermore, the individual circulation pump 7 is relatively heavy. By placing the relatively heavy circulation pump 7 at the bottom of the cabinet 1, this application can lower the overall center of gravity of the device, improve the stability of the whole machine during transportation and operation, and avoid tipping over due to the high center of gravity.

[0197] Based on this, the bottom of the cabinet 1 is used to fix the circulation pump 7 and to support the installation and removal of the circulation pump 7 along the second direction b, so that the bottom of the cabinet 1 can support the removal of the circulation pump 7 along the second direction b.

[0198] Along the second direction b, a portion of the circulating pump 7 protrudes from the heat exchanger 2 and extends toward the first frame 101 (not shown in this figure). By extending a portion of the circulating pump 7 toward the first frame 101, the circulating pump 7 can be replaced or maintained using the maintenance port opened on the first frame 101, thereby improving the ease of maintenance of the device.

[0199] Specifically, the circulation pump 7 can be slidably connected to the cabinet 1, meaning the circulation pump 7 is slidably connected to the bottom of the cabinet 1 along the second direction b. This slidable connection between the circulation pump 7 and the bottom of the cabinet 1 allows for quick insertion and removal of the circulation pump 7 during installation, maintenance, or replacement. This ensures the structural stability and reliability of the device while improving the ease of assembly and disassembly of the circulation pump 7.

[0200] In some examples of embodiments of this application, there are guide rails and multiple pulleys between the bottom of the circulation pump 7 and the bottom of the cabinet 1. This application achieves a sliding connection between the circulation pump 7 and the bottom of the cabinet 1 by using a combination of guide rails and pulleys, thereby reducing the friction force that needs to be overcome when pulling out the circulation pump 7.

[0201] Figure 16 An exemplary schematic diagram of a circulating pump, guide rail, and pulleys provided in an embodiment of this application is shown. In this example, the guide rail 8 is located at the bottom of the cabinet 1 (not shown in this figure), and multiple pulleys 9 are located at the bottom of the circulating pump 7. In other examples, the guide rail 8 may be located at the bottom of the circulating pump 7, and multiple pulleys 9 may be located at the bottom of the cabinet 1.

[0202] To facilitate fixing the positions of the multiple pulleys 9, a support structure 10 is provided at the bottom of each circulation pump 7, and the pulleys 9 are located in the cavity of the support structure 10.

[0203] This application achieves a sliding connection between the circulating pump 7 and the bottom of the cabinet 1 by using a combination of guide rail 8 and pulley 9. The guide rail 8 guides and limits the movement path of the circulating pump 7, preventing it from tilting or colliding during movement and avoiding damage to surrounding pipes and connecting components, thereby improving the safety and reliability of maintenance operations.

[0204] Furthermore, this sliding connection structure makes full use of the space at the bottom of the cabinet 1, eliminating the need for additional operating areas in front of or to the side of the cabinet 1, which facilitates a compact layout of the overall device structure. Thus, while ensuring convenient and time-saving assembly and disassembly of the circulating pump 7, it also considers operational safety and space utilization.

[0205] Continue as Figure 16 As shown, the guide rail 8 extends along the second direction b, and multiple pulleys 9 are arranged along the second direction b.

[0206] To improve the stability of the circulating pump 7 during the pulling process, each circulating pump 7 is equipped with two guide rails 8 and two rows of pulleys 9. The symmetrical arrangement of the two guide rails 8 and the two rows of pulleys 9 can distribute the load during the pulling process, preventing the circulating pump 7 from tilting or shaking, thereby improving the stability and reliability of the pulling process.

[0207] like Figure 16 As shown, the guide rail 8 has a protrusion, and the plurality of pulleys 9 have recesses, with the protrusion extending into the recess to form a sliding connection. Alternatively, the guide rail 8 may have a recess, with the edges of the plurality of pulleys 9 extending into the recess to form a sliding connection.

[0208] The guide rail 8 has an inverted V-shaped tip facing the pulley 9, and the pulley 9 has an inverted V-shaped groove facing the guide rail 8. The inverted V-shaped tip extends into the inverted V-shaped groove to achieve a sliding connection. Alternatively, a mating structure of a U-shaped tip and a U-shaped groove, or other convex-concave mating structures, can be used.

[0209] In some other examples of embodiments of this application, a friction structure layer is provided between the bottom of the circulation pump 7 and the bottom of the cabinet 1. By providing a friction structure layer at the bottom of the cabinet 1, the bottom of the circulation pump 7 contacts the friction structure layer and achieves relative sliding. This structure is simple and compact, does not require additional mechanical parts such as guide rails and pulleys, and does not occupy the space of the third direction c of the cabinet 1, which is conducive to the compactness of the overall layout of the cabinet 1.

[0210] Figure 17 An exemplary schematic diagram of a circulating pump and friction structure layer provided in an embodiment of this application is shown. In this example, the friction structure layer 11 is disposed on the bottom of the cabinet 1 facing the circulating pump 7.

[0211] In other examples, the friction structure layer 11 may be disposed on the side of the circulation pump 7 facing the bottom of the cabinet 1. The location of the friction structure layer 11 is not limited here, as long as it is disposed between the contact surface between the circulation pump 7 and the bottom of the cabinet 1.

[0212] To facilitate the fixing of the friction structure layer 11, a support structure 10 is provided at the bottom of each circulation pump 7, and the friction structure layer 11 is in contact with the bottom surface of the support structure 10.

[0213] In this embodiment, the friction coefficient between the friction structure layer 11 and the bottom of the circulation pump 7 is less than or equal to 0.3. The lower friction coefficient can reduce the sliding resistance of the circulation pump 7 during the pushing or pulling process, so that the operator can easily disassemble and assemble the circulation pump 7 without the aid of external tools.

[0214] Continue as Figure 17 As shown, the friction structure layer 11 extends along the second direction b, or it can be that the friction structure layer 11 is set on the entire bottom surface of the support structure 10 or the part of the bottom of the cabinet 1 that contacts the support structure 10.

[0215] Figure 18A schematic diagram of a secondary-side inlet pipeline and two circulating pumps provided in an embodiment of this application is illustrated by way of example. In this example, the circulating pump 7 has an inlet 701 and an outlet 702, wherein the inlet 701 is connected to a portion of the secondary-side inlet pipeline 302 via a first pipeline 1201, and the outlet 702 of the circulating pump 7 is connected to another portion of the secondary-side inlet pipeline 302 via a second pipeline 1202. The first pipeline 1201 is used to output a first coolant to the circulating pump 7, and the second pipeline 1202 is used to receive a second coolant from the circulating pump 7.

[0216] It is understandable that the circulation pump 7 and the first pipe 1201 and the second pipe 1202 on both sides of the circulation pump 7 divide the secondary side liquid inlet pipe 302 into two parts, and are connected through the circulation pump 7 and the first pipe 1201 and the second pipe 1202 on both sides of the circulation pump 7.

[0217] like Figure 18 As shown, the liquid inlet 701 of the circulating pump 7 faces the first frame 101 (not shown in this figure), so that the heat exchanger 2 (not shown in this figure) can be placed behind the circulating pump 7. Since the heat exchanger 2 has passed the inspection before leaving the factory and does not require maintenance during use, placing it at the rear can make full use of the non-maintenance area space behind the cabinet 1. By placing the circulating pump 7, which requires maintenance, at the front, all the space in front of the cabinet 1 is reserved for the components that need maintenance, thereby achieving full frontal maintenance of the cooling capacity distribution device 100.

[0218] Return to Figure 2 As shown, when the secondary side inlet 1072 is far from the first frame 101 (not shown in this figure), that is, when the secondary side inlet 1072 is located behind the liquid inlet 701 along the second direction b, the end of the secondary side liquid inlet pipe 302 away from the secondary side inlet 1072 is inclined toward the first pipe 1201, so that the circulating pump 7 can be placed as close as possible to the front of the cabinet 1, so as to shorten the distance between the circulating pump 7 and the front of the cabinet 1, freeing up the rear space, which can be used to install a heat exchanger 2 with a stronger heat exchange capacity.

[0219] To prevent gas accumulation and gas blockage, and to ensure the self-priming capability and operational stability of the circulating pump 7, the outlet 702 of the circulating pump 7 is positioned facing the top of the cabinet 1 (not shown in this figure).

[0220] Continue as Figure 18As shown, the second pipe 1202 extends along the third direction c. When the circulating pump 7 starts, stops, or experiences a sudden change in speed, the water hammer pressure wave generated within the pipe propagates to the second pipe 1202. Due to the gravity of the vertical liquid column within the second pipe 1202, the peak value of the pressure fluctuation is buffered and absorbed, thereby weakening the water hammer intensity. This process reduces the risk of damage to the thin plates and welded joints inside the heat exchanger 2 from the impact pressure, extending the service life of the heat exchanger 2.

[0221] Furthermore, when the second coolant flows from the lower circulation pump 7 to the upper heat exchanger 2, it is first transported upwards through the second pipe 1202. During the vertical upward flow, the vertically rising liquid flow can simultaneously utilize the kinetic energy of the second coolant itself and the buoyancy of the tiny particles in the second coolant, keeping the particles in a suspended state. The upward flow direction is opposite to the natural settling direction of the particles under gravity, ensuring that the particles are always carried and lifted, making them less prone to sedimentation.

[0222] When the particles enter the heat exchanger 2 with the liquid flow, due to the high initial flow velocity provided by the second pipe 1202, the particles are not easy to settle at the bottom of the heat exchanger 2, but are carried through the narrow plate channels inside the heat exchanger 2.

[0223] The plate channels of heat exchanger 2 have a complex corrugated structure, which can easily create low-velocity zones in localized areas due to horizontal or downward liquid flow, thereby accelerating particle settling. However, in this application, the second pipe 1202 provides a higher initial flow velocity, which continuously disrupts the particle settling conditions, reducing the risk of impurities accumulating on the plate surface or at channel corners, and carrying away any remaining small particles from the system. These particles are then filtered out by a filter downstream of heat exchanger 2, enhancing the system's self-cleaning capability, maintaining or improving the heat exchange efficiency of heat exchanger 2, and reducing maintenance frequency.

[0224] The orientation of the second pipeline 1202 is not limited to this. When the outlet 702 of the circulating pump 7 is set at an acute angle to the vertical direction, the second pipeline 1202 can be set at an angle accordingly.

[0225] Continue as Figure 18 As shown, the first pipe 1201 also extends along the third direction c, which can save the space occupied by the first pipe 1201 in the horizontal direction, optimize the pipe layout, and reduce the floor area of ​​the cold energy distribution device 100.

[0226] To facilitate the removal and maintenance of the circulation pump 7, the first pipeline 1201 and the second pipeline 1202 include a first section and a second section extending along a third direction c. The first section and the second section are detachably connected. When the first section and the second section are detached, the circulation pump 7 is used to move along a second direction b under the action of an external force.

[0227] In this embodiment, both the first pipe 1201 and the second pipe 1202 extend along a third direction c and are respectively constructed as two detachably connected sections. When the circulating pump 7 needs maintenance or replacement, it is only necessary to disconnect the detachable connection between the corresponding two pipe sections without disassembling any other pipes or components, thus separating the circulating pump 7 from other components. Since the pipes extend along a third direction c and their detachable connections are arranged vertically, after disconnection, the circulating pump 7 can be directly moved out of the cabinet 1 along the second direction b without interfering with the disconnected pipes, allowing for easy removal. This design avoids the cumbersome operation of cutting or re-welding the first pipe 1201 and the second pipe 1202 required in traditional maintenance, simplifying the operation steps, reducing maintenance difficulty, and improving work efficiency. Therefore, while ensuring the compactness of the system's piping layout, it enhances the convenience and efficiency of maintaining the circulating pump 7.

[0228] Specifically, a butterfly valve 13 is installed between the first and second sections. By operating the butterfly valve 13 to cut off the pipeline, the circulation pump 7 can be separated from the inlet and outlet pipelines. Optionally, a ball valve or a shut-off valve can also be installed to achieve the same on / off control function.

[0229] In other examples of embodiments of this application, in order to achieve detachable maintenance of the circulating pump 7, detachable connections can be made between the inlet 701 of the circulating pump 7 and the first pipeline 1201, and between the outlet 702 and the second pipeline 1202, respectively, through flange assemblies. By removing the fasteners on the flange assembly, the circulating pump 7 can be removed as a whole.

[0230] Continue as Figure 18 As shown, both the first pipe 1201 and the second pipe 1202 include a telescopic structure, which can shrink and extend along the length of the third direction c.

[0231] This application provides a telescopic structure on the first pipe 1201 and the second pipe 1202. The telescopic structure can be appropriately retracted when the circulation pump 7 is removed, providing clearance for the circulation pump 7 to move out of the cabinet 1 along the second direction b, facilitating the quick disassembly and removal of the circulation pump 7. At the same time, the telescopic structure can compensate for the processing tolerances and assembly errors of the circulation pump 7 itself, avoiding interference or poor sealing at the connection point during disassembly and assembly due to rigid connection.

[0232] It is understood that the location and number of retractable structures are not limited to the aforementioned embodiments. Retractable structures can be installed on any one or both of the first pipe 1201 and the second pipe 1202, and one or more retractable structures can be installed on each pipe. This application does not impose any restrictions on this.

[0233] Return to Figure 10As shown, the first pipeline 1201 and the heat exchanger 2 are respectively arranged on both sides of the second pipeline 1202 along the second direction b, so that the second pipeline 1202 is arranged closer to the heat exchanger 2. This shortens the length of the connecting pipeline between the two when connecting the second pipeline 1202 and the heat exchanger 2, reduces mutual interference between the pipelines, and makes the pipeline layout more compact.

[0234] Specifically, the above layout can achieve spatial separation of the first pipeline 1201 and the second pipeline 1202 in the second direction b. This arrangement can simplify the pipeline layout, avoid cross interference between the two pipelines, and thus avoid extending the pipeline or occupying additional space due to avoidance, thereby reducing the space occupied by the pipeline in the second direction b, and providing space for replacing the heat exchanger 2 with a larger size.

[0235] Return to Figure 6 As shown, the cabinet 1 is used to accommodate two circulating pumps 7, which are arranged along the first direction a and distributed in the gap between the heat exchanger 2 and the bottom of the cabinet 1.

[0236] This embodiment of the application, by setting two circulation pumps 7, can not only expand the flow range of the second coolant flowing through the pipeline and provide greater circulation power for the second coolant, but also arrange the two circulation pumps 7 in parallel, thereby achieving mutual backup and providing redundancy.

[0237] In other examples of embodiments of this application, the circulation pump 7 may be configured as one or more, depending on the requirement for the second coolant flow range. The arrangement of the circulation pump 7 can be adaptively adjusted according to the actual layout inside the cabinet 1, for example, multiple circulation pumps 7 may be arranged side by side along the first direction a, and this application does not limit this.

[0238] Continue as Figure 18 As shown, cabinet 1 (not shown in this figure) is used to accommodate the first manifold 1401 and the second manifold 1402. The inlet 701 of the two circulation pumps 7 is used to receive the second coolant through the first manifold 1401, and the outlet 702 of the two circulation pumps 7 is used to output the second coolant to the second manifold 1402. The second manifold 1402 is used to transmit the second coolant to the heat exchanger 2, thereby realizing the diversion and convergence of the second coolant.

[0239] Specifically, the inlets 701 of the two circulating pumps 7 are connected to the first manifold 1401 via a first pipe 1201, and the outlets 702 of the two circulating pumps 7 are connected to the second manifold 1402 via two second pipes 1202. Furthermore, the first manifold 1401 is connected to a portion of the secondary inlet pipe 302, and the second manifold 1402 is connected to the other portion of the secondary inlet pipe 302. This allows for the parallel connection of the two circulating pumps 7, creating a parallel redundant configuration that serves as a backup for each other.

[0240] This embodiment of the application divides the flow on both sides near the two circulating pumps 7, and then merges the flow through the first manifold 1401 and the second manifold 1402, so that a single pipe can simultaneously connect the corresponding inlet and outlet ports of the two circulating pumps 7. This eliminates the need for additional pipe length in the merging section, thereby shortening the overall pipe length, reducing the pipe's occupation of the cabinet's internal space, and making the layout more compact.

[0241] The expandable structure on the first pipe 1201 and the second pipe 1202 is also used to compensate for the machining tolerances and assembly errors of the first manifold 1401 and the second manifold 1402 themselves, so as to avoid interference or poor sealing at the connection point during disassembly and assembly due to rigid connection.

[0242] like Figure 18 As shown in the figure, in this embodiment, two circulation pumps 7 are distributed along the first direction a at the bottom of the cabinet 1 (not shown in this figure), and the first manifold 1401 and the second manifold 1402 also extend along the first direction a. Since the circulation pumps 7 and the manifolds extend in the same direction, the inlet 701 of each circulation pump 7 can be directly connected to the first manifold 1401 nearby, and the outlet 702 can be directly connected to the second manifold 1402 nearby. The connecting pipes are short and simple, and there will be no crossing or interference between them.

[0243] Furthermore, this arrangement shortens the required pipe length when connecting in parallel, reducing the space occupied by the pipes and decreasing frictional resistance and pressure loss. At the same time, the pipe layout is simpler, facilitating installation, disassembly, and subsequent maintenance.

[0244] Return to Figure 10As shown, along the second direction b, the first manifold 1401 and the second manifold 1402 are distributed in the gap between the heat exchanger 2 and the first frame 101 (not shown in this figure), while the four inlet and outlet liquid pipes on both sides of the heat exchanger 2 are arranged between the heat exchanger 2 and the third frame 103 (not shown in this figure) or the fourth frame 104 (not shown in this figure), thus achieving spatial separation between the manifold and the inlet and outlet liquid pipes. The two pipe sections are arranged independently without needing to make way for each other, which simplifies the overall pipe layout and shortens the length of all pipes, thereby reducing the space occupied by the pipes inside the cabinet 1 and providing space for replacing the heat exchanger 2 with a larger size.

[0245] Furthermore, along the second direction b, the second manifold 1402 is located between the first manifold 1401 and the heat exchanger 2, making the first manifold 1401 closer to the inlet 701 of the circulating pump 7, while the second manifold 1402 is closer to the outlet 702 of the circulating pump 7 and the heat exchanger 2. This not only shortens the pipe length between the second manifold 1402 and the heat exchanger 2, but also achieves spatial separation of the first pipe 1201 and the second pipe 1202 in the second direction b. This arrangement simplifies the pipe layout and avoids cross-interference between the two pipes, thus eliminating the need to extend the pipes or occupy additional space due to avoidance, thereby reducing the space occupied by the pipes in the second direction b and providing space for replacing the larger heat exchanger 2.

[0246] Continue as Figure 18 As shown, the second manifold 1402 includes a plurality of mounting holes spaced apart along the first direction a. The plurality of mounting holes are used to mount a plurality of sensors respectively. The power supply device 6 (not shown in this figure) is used to adjust the flow rate of the second coolant according to the detection signals of the plurality of sensors.

[0247] This application utilizes multiple sensors installed on the second manifold 1402 to monitor the flow rate of the second coolant flowing through the circulating pump 7 in real time. The acquired detection data is transmitted as a feedback signal to the power supply device 6, which adjusts the speed of the circulating pump 7 accordingly. This allows the flow rate of the second coolant to be precisely adjusted to the target value as needed, achieving closed-loop flow control and preventing system energy efficiency degradation or operational instability caused by flow deviation.

[0248] It is understandable that multiple sensors can also be installed on the primary side inlet pipe 301, the secondary side inlet pipe 302, the primary side outlet pipe 303, the secondary side outlet pipe 304, the replenishment tank 5, and the first manifold pipe 1401 to achieve data monitoring.

[0249] The cooling capacity distribution device 100 in this embodiment requires the flow rate of the second coolant flowing through the secondary side outlet pipe 304 to be adjusted within the range of 10%-100%. When the speeds of both circulating pumps 7 are adjusted to the lowest level, the flow rate of the second coolant after exiting the two circulating pumps 7 in actual operation is still higher than 10%, which cannot meet the usage requirements. At this time, a bypass pipe can be connected in parallel between the first manifold 1401 and the second manifold 1402. The location of the bypass pipe will be described below.

[0250] like Figure 18 As shown, cabinet 1 is used to house bypass pipe 15, which connects the first manifold 1401 and the second manifold 1402. When adjusting the flow rate of the circulating pump 7, the speeds of both circulating pumps 7 are first adjusted to their lowest settings, then one of the circulating pumps 7 is shut off, reducing the flow rate to 25%. Then, the valve of bypass pipe 15 is opened, allowing some of the second coolant to flow back into the circulating pump 7. By adjusting the opening of this valve, the flow rate of the second coolant flowing through the secondary side outlet pipe 304 is precisely reduced to the required value.

[0251] This method expands the adjustment range of the second coolant flow rate through the secondary side outlet pipe 304, enabling flexible control of the second coolant flow rate over a wider range. Since the flow rate that the valve needs to adjust is relatively small, the valve size can be set smaller, and less second coolant flows through the bypass pipe 15, reducing the wasted work done by the circulating pump 7 and minimizing resource waste.

[0252] The bypass pipe 15 extends along the second direction b. The flow direction of the second coolant flowing through the bypass pipe 15 is from the second manifold 1402 to the first manifold 1401. This flow direction is opposite to the flow direction of the first coolant flowing through the circulating pump 7. Thus, the second coolant flowing through the second manifold 1402 can flow back into the first manifold 1401, thereby reducing the flow rate of the second coolant flowing out of the second manifold 1402.

[0253] The valve described above is used to open when the flow rate of the second coolant flowing out of the second manifold 1402 exceeds a threshold value. This threshold value is determined by the system's lower limit requirement for the second coolant flow rate, and can be set to, for example, 10% of the rated flow rate of the circulating pump 7. When the actual output flow rate of the circulating pump 7 is higher than the system requirement, and the speed adjustment range of the circulating pump 7 is limited, i.e., it has reached the minimum speed or the lower limit of the frequency converter and cannot be further reduced, the valve is opened to return the excess flow rate to the first manifold 1401, thereby achieving precise flow rate regulation.

[0254] Return to Figure 2As shown, along the first direction a, the gap between the power supply device 6 and the third frame 103 is used to accommodate the first filter 16, which is used to filter the second coolant.

[0255] continue Figure 2 As shown, along the first direction a, the gap between the circulating pump 7 and the replenishment tank 5 and the third frame 103 is used to accommodate the primary side liquid outlet pipe 303 and the secondary side liquid outlet pipe 304. The primary side liquid outlet pipe 303 is used to receive the first coolant from the heat exchanger 2, and the secondary side liquid outlet pipe 304 is used to receive the second coolant from the heat exchanger 2. The first filter 16 is connected to the secondary side liquid outlet pipe 304.

[0256] In this embodiment, the first filter 16 and the secondary side liquid outlet pipe 304 are arranged in the gap between the circulating pump 7 or power supply device 6 and the third frame 103, making full use of the space. At the same time, the first filter 16 is arranged close to the secondary side liquid outlet pipe 304, thereby shortening the length of the connecting pipe required to connect the first filter 16 to the secondary side liquid outlet pipe 304 and reducing flow resistance and leakage risk.

[0257] Alternatively, the first filter 16 can also be set in the gap between the replenishment tank 5 and the third frame 103, so that the first filter 16 is also set close to the secondary side inlet pipe 302.

[0258] In other examples of embodiments of this application, the first filter 16 may be disposed within the gap between the replenishment tank 5, the power supply device 6, and the third frame 103. As long as the first filter 16 is arranged close to the third frame 103, its installation height can be determined according to the actual pipeline routing and layout requirements; this application does not impose any restrictions on this.

[0259] In some other examples of embodiments of this application, the gap between the power supply device 6 and the replenishment tank 5 and the third frame 103 may be used to accommodate the primary side liquid outlet pipe 303 and the secondary side liquid outlet pipe 304, and the gap between the circulation pump 7 and the third frame 103 may be used to accommodate the first filter 16.

[0260] The first filter 16 extends along the second direction b and includes a maintenance window facing the maintenance opening of the first frame 101 (not shown in this figure) so that the filter element of the first filter 16 can pass through the maintenance window and be pulled out or inserted into the first filter 16 along the second direction b.

[0261] In this embodiment, multiple first filters 16 extend along the second direction b, and the maintenance windows are all oriented toward the maintenance port, so that the filter element of the first filter 16 can be directly pulled out from the maintenance window along the second direction b, and then replaced or maintained through the maintenance port of the first frame 101 without disassembling other components. The maintenance operation is simple and convenient, further improving the maintainability and space utilization of the system.

[0262] Continue as Figure 2 As shown, cabinet 1 is used to house one or more first filters 16. When multiple first filters 16 are installed, if one filter fails to function properly due to blockage, damage, or maintenance, the remaining filters can continue to perform the filtration task, thereby ensuring continuous system operation without the need for downtime for replacement.

[0263] Multiple first filters 16 are arranged along the third direction c, thereby saving the width dimension of the cabinet 1. When the space of the cabinet 1 along the first direction a is large enough, multiple first filters 16 can also be arranged along the first direction a to save the height of the cabinet 1. The arrangement direction of multiple first filters 16 can be flexibly selected according to the actual space size.

[0264] Continue as Figure 2 As shown, along the first direction a, the gap between the coolant tank 5 and the power supply device 6 and the fourth frame 104 is used to accommodate the second filter 17, which is used to filter the first coolant. In this embodiment, the second filter 17 is placed in the gap between the coolant tank 5 and the power supply device 6 and the fourth frame 104, making full use of this space. At the same time, the second filter 17 is arranged close to the primary side inlet pipe 301, thereby shortening the length of the connecting pipe required to connect the second filter 17 to the primary side inlet pipe 301 and reducing flow resistance and leakage risk. Alternatively, the second filter 17 can also be placed in the gap between the coolant tank 5 and the power supply device 6 and the third frame 103, so that the second filter 17 is arranged close to the primary side outlet pipe 303.

[0265] In other examples of embodiments of this application, the second filter 17 may be disposed only in the gap between the replenishment tank 5 and the fourth frame 104, or only in the gap between the power supply device 6 and the fourth frame 104. As long as the second filter 17 is arranged close to the third frame 103 or the fourth frame 104, its installation height can be determined according to the actual pipeline routing and layout requirements, and this application does not impose any restrictions on this.

[0266] Furthermore, the gap between the primary inlet pipe 301 and the top of the cabinet 1 is used to accommodate the second filter 17, which is connected to the primary inlet pipe 301. Alternatively, the gap between the primary inlet pipe 301 and the bottom of the cabinet 1 can also be used to accommodate the second filter 17.

[0267] In this embodiment, the second filter 17 is placed in the gap between the primary side liquid inlet pipe 301 and the top or bottom of the cabinet 1, which can make full use of the space. At the same time, the second filter 17 is arranged close to the primary side liquid inlet pipe 301, thereby shortening the length of the connecting pipe required to connect the second filter 17 to the primary side liquid inlet pipe 301 and reducing flow resistance and leakage risk.

[0268] The second filter 17 includes a maintenance window that faces the top of the cabinet 1, i.e., the fifth frame 105, along a third direction c. The maintenance window is used to support the installation and removal of the filter element of the second filter 17 along the third direction c.

[0269] The gap between the primary inlet pipe 301 and the top of the cabinet 1 is located on the side of the cabinet 1 near the first frame 101, so that the filter element of the second filter 17 can be directly pulled out from the maintenance window along the third direction c, and then replaced or maintained through the maintenance port of the first frame 101 without disassembling other parts. The maintenance operation is simple and convenient, further improving the maintainability and space utilization of the system.

[0270] Continue as Figure 2 As shown, along the first direction a, the gap between the power supply device 6 and the fourth frame 104 is used to accommodate the expansion tank 18, which is used to regulate the pressure of the second coolant.

[0271] Along the first direction a, the gap between the circulating pump 7 and the replenishment tank 5 and the fourth frame 104 is used to accommodate the primary side liquid inlet pipe 301 and the secondary side liquid inlet pipe 302. The primary side liquid inlet pipe 301 is used to transmit the first coolant to the heat exchanger 2, and the secondary side liquid inlet pipe 302 is used to transmit the second coolant to the heat exchanger 2. The expansion tank 18 is connected to the secondary side liquid inlet pipe 302.

[0272] In this embodiment, the expansion tank 18 and the secondary side liquid inlet pipe 302 are arranged in the gap between the circulating pump 7 or the power supply device 6 and the fourth frame 104, making full use of the space. At the same time, the expansion tank 18 is arranged close to the secondary side liquid inlet pipe 302, thereby shortening the length of the connecting pipe required to connect the expansion tank 18 to the secondary side liquid inlet pipe 302 and reducing flow resistance and leakage risk.

[0273] Alternatively, the expansion tank 18 can be located in the gap between the replenishment tank 5 and the fourth frame 104, so that the expansion tank 18 is also located close to the secondary side inlet pipe 302.

[0274] In other examples of embodiments of this application, the expansion tank 18 may be disposed within the gap between the replenishment tank 5, the power supply device 6, and the fourth frame 104. As long as the expansion tank 18 is arranged close to the fourth frame 104, its installation height can be determined according to the actual pipeline routing and layout requirements, and this application does not impose any restrictions on this.

[0275] In some other examples of embodiments of this application, the gap between the power supply device 6 and the replenishment tank 5 and the fourth frame 104 may be used to accommodate the primary side liquid inlet pipe 301 and the secondary side liquid inlet pipe 302, and the gap between the circulation pump 7 and the fourth frame 104 may be used to accommodate the expansion tank 18.

[0276] Furthermore, the gap between the secondary inlet pipe 302 and the top of the cabinet 1 is used to accommodate the expansion tank 18, which is connected to the secondary inlet pipe 302. Alternatively, the gap between the secondary inlet pipe 302 and the bottom of the cabinet 1 can also be used to accommodate the expansion tank 18.

[0277] In this embodiment, the expansion tank 18 is placed in the gap between the secondary side liquid inlet pipe 302 and the top or bottom of the cabinet 1. This space can be fully utilized, and the expansion tank 18 is arranged close to the secondary side liquid inlet pipe 302, thereby shortening the length of the connecting pipe required to connect the expansion tank 18 to the secondary side liquid inlet pipe 302 and reducing flow resistance and leakage risk.

[0278] The gap between the secondary side liquid inlet pipe 302 and the top of the cabinet 1 is located on the side of the cabinet 1 close to the first frame 101, so that the expansion tank 18 can be directly pulled out along the third direction c, and then replaced or maintained through the maintenance port of the first frame 101 without disassembling other parts. The maintenance operation is simple and convenient, further improving the maintainability and space utilization of the system.

[0279] Continue as Figure 2 As shown, the expansion tank 18 includes two expansion tanks, which are arranged along the second direction b and connected in parallel in the pipeline. Each expansion tank is equipped with an independent shut-off valve, forming a redundant backup system.

[0280] Figure 19An exemplary schematic diagram of an expansion tank and support frame provided in an embodiment of this application is shown. In this example, the fourth frame 104 (not shown in this figure) is used to fix the support frame 19, which is used to fix the expansion tank 18 and to support the installation and removal of the expansion tank 18 along the second direction b. By fixing the support frame 19 on the fourth frame 104 and installing the expansion tank 18 on the support frame 19, this application enables the expansion tank 18 to be pulled out and installed along the second direction b, thus allowing it to be quickly extracted for gas replenishment or maintenance without disassembling any surrounding components. This improves the ease of operation in confined spaces, shortens maintenance downtime, and avoids misoperation or secondary damage to surrounding pipelines, sensors, and other components during installation and removal.

[0281] like Figure 19 As shown, the support frame 19 includes a first part 1901 and a second part 1902 that are slidably connected to each other. One side of the first part 1901 is fixedly connected to the fourth frame 104 (not shown in this figure), and the other side is constructed with a C-shaped cross section, forming a groove with an opening facing the expansion tank 18. The two expansion tanks 18 are fixedly connected to the second part 1902 by a crossbeam or connecting structure, so that the two expansion tanks 18 and the second part 1902 form an integral movable module. The second part 1902 extends into the C-shaped groove of the first part 1901, and the top and bottom of the second part 1902 form a sliding engagement with the upper and lower walls of the groove, respectively. Thus, the two expansion tanks 18 can slide together with the second part 1902 along the second direction b.

Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
