Description

Technical Field

[0001] The present disclosure relates to the technical field of data center cooling, and in particular to a heat exchange cabinet and a liquid cooling heat exchange system. Background Art

[0002] With the rapid development of ChatGPT, artificial intelligence technology has gradually become a cutting-edge development. The air cooling systems used in traditional data centers are gradually failing to meet the heat dissipation needs of servers, and liquid cooling technology has gradually become mainstream. Currently, the heat exchangers in liquid cooling systems mainly include distributed heat exchangers and centralized heat exchangers. Among them, centralized heat exchanger cold plate liquid cooling systems require redundant design, with one active and one backup or two active and one backup. However, this is costly, and when one heat exchanger is not faulty, the other heat exchanger is unused, resulting in waste. In distributed heat exchanger cold plate liquid cooling systems, each heat exchanger is responsible for only one liquid cooling cabinet, making redundant design impossible. In the event of a failure, the single liquid cooling cabinet must cease operation. Summary of the Invention

[0006] Each of the heat exchange devices includes a primary water inlet and outlet, a secondary water inlet and outlet, and an electrical interface, and the primary water inlet and outlet, the secondary water inlet and outlet, and the electrical interface included in each of the heat exchange devices are all arranged on the first side of the rack structure.

Based on this, when the heat exchange cabinet provided by the present disclosure is used to cool multiple liquid cooling cabinets in the computer room, it is only necessary to arrange the number of heat exchange devices in the heat exchange cabinet according to the needs of the liquid cooling cabinet, thereby realizing flexible regulation of the heat exchange device, reducing the waste of cooling capacity, and reducing costs while ensuring the needs of the liquid cooling cabinet.

[0026] With the rapid development of ChatGPT, artificial intelligence technology has gradually become a cutting-edge development. The advancement of artificial intelligence and high-density computing has led to continuous advancements in server chips, resulting in increased power consumption. This increased chip power places higher demands on server heat dissipation. Traditional data center air cooling systems are gradually failing to meet these demands. Furthermore, the PUE of air cooling systems remains high under the dual-carbon goals. This has led to the development of liquid cooling technology becoming mainstream. Currently, the more mature liquid cooling technologies on the market are mainly cold plate and immersion cooling.

[0027] Cold plate liquid cooling is an advanced heat dissipation technology suitable for high-performance computing environments such as data centers. Its core principle is to introduce coolant into the heat dissipation modules of servers or other devices, where it directly contacts and absorbs heat from the heat source. The flowing coolant then removes the heat and ultimately exhausts it from the system through a heat exchanger or condenser. Because cold plate liquid cooling requires minimal modifications to traditional air-cooled computer rooms, it is the fastest-growing data center liquid cooling technology.

[0028] Cold plate liquid cooling technology dissipates heat from the heating element by adding a cold plate device above the heating element. The cold plate device consists of a thermal contact material base and a shell. The shell is buckled on the thermal contact base. A closed cavity is left between the shell and the thermal contact base. The fluid can flow in the closed cavity. The thermal contact base is in direct contact with the heating element. The heat of the heating element is first transferred to the thermal contact base and then carried away by the liquid flowing in the closed cavity.

[0029] The cold plate liquid cooling system consists of a primary system and a secondary system. The primary system includes an outdoor cooling source, while the secondary system includes a cold plate assembly. The outdoor cooling source dissipates heat outdoors, while the cold plate assembly removes heat from the heating element. The coolant between the primary and secondary systems exchanges heat through a cooling distribution unit (CDU). During operation, the low-temperature coolant in the secondary system absorbs heat from the heating element, transforming into high-temperature coolant. It then enters the plate heat exchanger in the CDU, exchanges heat with the primary system coolant, and returns to low-temperature coolant. It then enters the heating element for heat exchange, completing the cycle. The high-temperature coolant in the primary system releases heat from the outdoor cooling source, transforming into low-temperature coolant. It then enters the CDU for heat exchange, transforming back into high-temperature coolant, and then enters the outdoor cooling source, completing the cycle.

[0030] Currently, data centers use two types of heat exchangers in cold plate liquid cooling systems: centralized and distributed. A centralized heat exchanger is a large unit, similar in size to a liquid-cooled cabinet. It sits in a row with the cabinets and provides heat exchange for the entire row, typically with one active unit and one standby, or two active units and one standby. A distributed heat exchanger, also known as a rack-mounted heat exchanger, is smaller and placed within the liquid-cooled cabinet. It typically occupies 4U of space within the cabinet and provides heat exchange for a single cabinet.

[0031] The inventors have discovered that in existing research on cold plate liquid cooling systems for data centers:

[0032] 1. Research on heat exchangers mainly focuses on the internal structure and optimization of internal design of heat exchangers, while there is currently no research on distributed or centralized heat exchangers. At present, cold plate liquid cooling systems that use centralized heat exchangers require redundant design due to safety considerations. Generally, they are set up with one in use and one in standby or two in use and one in standby. That is, when one unit is actually needed during operation, two units are installed, one in operation and one in standby; or when two units are needed, three units are installed, two in operation and one in standby. Such redundant design requires a high investment cost. When the heat exchanger is not faulty, the other heat exchanger is completely unused, resulting in waste. For example, if a row of liquid-cooled cabinets requires 400KW of cooling capacity, two centralized heat exchangers with a specification of 400KW need to be installed. The advantage of a cold plate liquid cooling system that uses a distributed heat exchanger is that one heat exchanger is only responsible for one liquid cooling cabinet. When a failure occurs, the affected area is only one liquid cooling cabinet. The disadvantage is that the current distributed heat exchanger cannot be designed with redundancy. When a failure occurs, the single liquid cooling cabinet it supplies cooling needs to stop running, and the distributed heat exchanger will occupy 4U of space in the liquid cooling cabinet, which means that the space for placing servers in a single liquid cooling cabinet is reduced.

[0033] 2. The research on liquid pipeline layout is not involved.

[0034] To overcome the aforementioned issues, the exemplary embodiments of the present disclosure provide a heat exchange cabinet. By integrating multiple heat exchange devices within the heat exchange cabinet and connecting the primary and secondary water inlets and outlets of the multiple heat exchange devices via a cable management structure, the heat exchange cabinet is quickly connected to the water loop network within the computer room. This improves installation efficiency. Furthermore, the integration of multiple heat exchange devices within the heat exchange cabinet frees up space within the liquid-cooled cabinet, thereby increasing server density within the liquid-cooled cabinet. Consequently, the multiple heat exchange devices integrated within the heat exchange cabinet can be flexibly configured according to the requirements of the liquid-cooled cabinet, avoiding the costly waste caused by excessive redundancy in centralized heat exchange devices.

[0035] Figure 1 FIG. 1 shows a schematic structural diagram of a heat exchange cabinet provided according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the heat exchange cabinet 100 provided in the embodiment of the present disclosure includes: a rack structure 110, multiple heat exchange devices 120, and multiple groups of support structures 130. The multiple groups of support structures 130 are spaced apart along the height direction of the rack structure 110 on the inner sidewall of the rack structure 110. Each group of support structures 130 is used to support the heat exchange device 120, ensuring that multiple heat exchange devices 120 can be integrated into the rack structure 110. It should be understood that the materials of the rack structure 110 and support structures 130 involved in the exemplary embodiments of the present disclosure can be any commercially available optional materials and are not limited here.

[0036] In practical applications, Figure 2 FIG. 1 shows a schematic structural diagram of a heat exchange device according to an exemplary embodiment of the present disclosure. Figure 2 As shown, each of the heat exchange devices 120 may include a circulating water pump 121, a make-up water pump 122, a plate heat exchanger 123, a valve (not shown), a power module 124, a management module 125, a primary water inlet and outlet 126, a secondary water inlet and outlet 127, and an electrical interface (not shown). The primary water inlet and outlet 126, the secondary water inlet and outlet 127, and the electrical interface of each heat exchange device are all located on the first side of the rack structure 110. The exterior of the heat exchange device 120 may be a square shell, on the surface of which the primary water inlet and outlet 126, the secondary water inlet and outlet 127, and the electrical interface (not shown) are provided. The primary water inlet and outlet 126 is connected to the primary water inlet and outlet pipeline 1261, which is connected to the plate heat exchanger 123. The secondary water inlet and outlet 127 is connected to the secondary water inlet and outlet pipeline 1271, which is connected to the plate heat exchanger 123. The circulating water pump 121 is used to provide power to the secondary water inlet and outlet pipeline 1271, and the make-up water pump 122 is used to replenish water to the water system pipeline of the heat exchange device 120. The valve of the heat exchange device 120 can be a proportional valve to control the flow rate of the primary water inlet and outlet pipeline 1261. The plate heat exchanger 123 is used to exchange heat between the primary and secondary water system pipelines. The power module 124 is used to power the circulating water pump 121, the make-up water pump 122, and the management module 125 in the heat exchange device 120.

[0037] like Figure 1 As shown, the rack structure 110 can be a box with openings at both ends, and multiple groups of support structures 130 are arranged on the inner sidewalls of the box with openings at both ends. The height of each group of support structures 130 located near the top and bottom of the rack structure 110 and the distance between two adjacent groups of support structures 130 can be set according to actual needs. For example, when each group of support structures 130 needs to support the same specifications of the heat exchange device 120, the height of each group of support structures 130 located near the top and bottom of the rack structure 110 and the distance between two adjacent groups of support structures 130 can be the same; when each group of support structures 130 needs to support different specifications of the heat exchange device 120, the height of each group of support structures 130 located near the top and bottom of the rack structure 110 and the distance between two adjacent groups of support structures 130 can be set according to the height of the heat exchange device 120 that each group of support structures 130 needs to support, so as to ensure that heat exchange devices 120 of different specifications can be integrated into the heat exchange cabinet 100 provided by the present disclosure.

[0038] To improve installation efficiency during installation, the multiple heat exchange devices in the heat exchange cabinet provided in the exemplary embodiment of the present disclosure are pre-assembled on multiple sets of support structures within the rack structure. Therefore, to minimize relative displacement of the heat exchange devices during installation, the height of each heat exchange device is equal to the height difference between two adjacent support structures, and the length of each heat exchange device is equal to the length of each set of support structures, that is, the length of each heat exchange device is equal to the length of the guide rails included in each set of support structures. It should be understood that the length of each heat exchange device is parallel to the direction in which the heat exchange device is inserted into the heat exchange cabinet, or is aligned with the direction in which the guide rails extend.

[0039] As can be seen from the above, in the heat exchange cabinet provided by the exemplary embodiment of the present disclosure, by providing a rack structure and multiple groups of support structures, and the multiple groups of support structures are arranged on the inner side wall of the rack structure at intervals along the height direction of the rack structure, the multiple heat exchange devices included in the heat exchange cabinet can be supported by the corresponding groups of support structures, so that multiple heat exchange devices can be integrated in the heat exchange cabinet, saving space in the liquid cooling cabinet, so that the server density in the liquid cooling cabinet is improved, and thus the computing power of the server can be improved. Based on this, when the heat exchange cabinet provided by the present disclosure is used to cool multiple liquid cooling cabinets in the computer room, it is only necessary to arrange the number of heat exchange devices in the heat exchange cabinet according to the needs of the liquid cooling cabinet, thereby realizing flexible regulation of the heat exchange device, reducing the waste of cooling capacity, and reducing costs while ensuring the needs of the liquid cooling cabinet.

[0040] As a possible implementation, Figure 3 FIG. 1 shows a schematic diagram of the installation structure of the rack structure and the support structure provided according to an exemplary embodiment of the present disclosure. Figures 1 to 3 As shown, each set of support structures 130 includes a guide rail 131 and a first stopper 132. The guide rail 131 is fixed to the inner sidewall of the rack structure 110. The guide rail 131 extends along the second side of the rack structure 110 toward the first side of the rack structure 110, with the second side of the rack structure 110 and the first stopper 132 being located at the end of the guide rail near the first side of the rack structure 110. By providing the guide rail 131 and the first stopper 132, each heat exchange device 120 can extend into the interior of the rack structure 110 along the extension direction of the guide rail 131 and stop moving under the restraining action of the first stopper 132, thereby ensuring that multiple heat exchange devices 120 can be integrated into the rack structure 110. This saves space within the liquid cooling cabinet, leaving more room for servers, and maximizing space utilization within the liquid cooling cabinet.

[0041] In practical applications, such as Figures 1 to 3As shown, the first stopper 132 can be a baffle connected to the sidewall of the opening on the first side of the frame structure 110. The first side of the baffle is connected to the sidewall of the opening on the first side of the frame structure 110, and the second side of the baffle can be connected to the guide rail 131. It should be noted that the second side of the baffle can be fixedly connected to the guide rail 131, or it can be arranged in contact with the guide rail 131, and this is not limited here. The first side of the baffle is connected to the second side of the baffle. For example, when the baffle is a rectangular baffle, the first side of the baffle can be the wide side of the rectangle, and the second side of the baffle can be the long side of the rectangle.

[0042] Figure 4 Schematic diagram of the structure of each group of support structures provided according to an exemplary embodiment of the present disclosure is shown. Figure 4 As shown, to further enhance the limiting effect of the first limiting member 132 on the heat exchange device 120, a baffle is used as an example for illustration. The guide rail 131 included in each set of support structures 130 can be connected to the first position of the baffle. That is, within the heat exchange device 120 accommodation space formed by two adjacent sets of support structures 130, the opening portion near the first side of the rack structure 110 is simultaneously provided with two baffles to block the movement of the heat exchange device 120. It should be understood that the first position here can be any position on the contact surface between the baffle and the guide rail, excluding the edge of the baffle.

[0043] Because the heat exchanger cabinet provided in the exemplary embodiments of the present disclosure has its heat exchange device integrated into its frame structure before formal use, workers may risk the heat exchanger device shifting or falling out during installation and movement. Furthermore, once the heat exchanger cabinet is in use, there's a chance it could shift, potentially causing the aforementioned issues.

[0044] In order to solve the above problem, the heat exchange cabinet provided in the exemplary embodiment of the present disclosure may further include a second limiting member or a shielding structure.

[0045] like Figures 1 to 4 As shown, when each set of support structures 130 includes a second stopper (not shown) connected to the guide rail 131, the second stopper is provided at the end of the guide rail on the first side facing away from the frame structure 110. By providing the second stopper, it is ensured that when the heat exchange device 120 is installed in the frame structure 110, the heat exchange device 120 is confined within the support structure 130 by the second stopper. This ensures that when workers move and install the frame structure 110, and when the heat exchange cabinet 100 is subsequently moved during use, the heat exchange device 120 located within the frame structure 110 of the heat exchange cabinet 100 will not undergo relative displacement, thereby ensuring that the water system pipelines of the heat exchange device 120 can be stably connected to the water system pipelines of the cable management structure 140.

[0046] For example, the second stopper may be a stopper pin, which may be positioned at a position of the guide rail proximate to the second side of the frame structure, or at an edge of a sidewall of the frame structure proximate to the second side. The product model and other characteristics of the stopper pin may be selected based on practical needs. Any commercially available stopper pin that meets the requirements of this disclosure is within the scope of this disclosure.

[0047] like Figures 1 to 4 As shown, when the heat exchange cabinet 100 includes a shielding structure 133, the shielding structure 133 is rotatably disposed on the second side of the frame structure 110, with the first and second sides of the frame structure 110 facing each other. By providing the shielding structure 133, when the heat exchange device 120 is integrated within the frame structure 110, the shielding structure 133 can shield the opening on the second side of the frame structure 110. This ensures that when the heat exchange cabinet 100 is moved, the heat exchange device 120 within the frame structure 110 of the heat exchange cabinet 100 does not move relative to the heat exchange device 120, thereby ensuring a stable connection between the heat exchange device 120 and the other structures.

[0048] For example, Figures 1 to 4 As shown, the shielding structure 133 can be a shielding plate. The shape of the shielding plate can be designed based on the shape of the opening on the second side of the rack structure 110, and is not limited here. The shielding plate can be connected to the sidewall of the second side of the rack structure 110 via a hinge. After the heat exchange device 120 corresponding to the cooling capacity required by the liquid-cooled cabinet is installed, the shielding plate can be rotated so that the shielding plate covers the opening on the second side of the rack structure 110, so that the opening on the second side of the rack structure 110 is in a closed state, thereby ensuring that the multiple heat exchange devices 120 located in the rack structure 110 are stuck between the shielding plate and the first stopper 132, ensuring that the multiple heat exchange devices 120 do not undergo relative displacement during the movement of the heat exchange cabinet 100. It should be understood that when the shielding plate covers the opening on the second side of the frame structure 110, a locking structure may be provided at a corresponding position on the opening on the second side of the frame structure 110. This locking structure may be a mechanical locking structure, an electromagnetic locking structure, or the like, without limitation herein. It should be noted that this locking structure is a commercially available product, and any commercially available locking structure that meets the requirements of this disclosure is within the scope of this application and will not be further described.

[0049] In actual applications, multiple heat exchangers can be installed in the above-mentioned rack structure, and N+1, N+2 or N+x heat exchangers can be installed according to demand, that is, one, two or more backup heat exchangers are left on the rack structure to facilitate backup use when the heat exchanger fails to work abnormally. At the same time, in the heat exchange cabinet provided by the present disclosure, multiple groups of support structures can be set to flexibly adjust the number of working heat exchangers. For example, in an actual application scenario, 20 liquid-cooled cabinets were originally planned to be used at full load, but only 10 liquid-cooled cabinets were installed in the initial stage, and the heat exchangers in the heat exchange cabinets were set according to the cooling capacity requirements of the 20 liquid-cooled cabinets. At this time, the heat exchangers in the heat exchange cabinets can be flexibly adjusted. The heat exchangers that match the cooling capacity required by the 10 liquid-cooled cabinets can be used first, or only the heat exchangers that match the cooling capacity required by the 10 liquid-cooled cabinets can be installed in the initial stage to reduce cooling waste.

[0050] Figure 5 The structure diagram of the cable management structure provided according to the exemplary embodiment of the present disclosure is shown. Figure 1 ,like Figures 1 to 5 As shown, the above-mentioned heat exchange cabinet also includes a wiring structure 140, which includes a shielding surface 141, a shell 142, and a plurality of primary side water inlets and outlets 1411 and a plurality of secondary side water inlets and outlets 1412 arranged on the shielding surface 141. The shielding surface 141 is arranged on the first side of the rack structure 110. Each primary side water inlet and outlet 1411 included in the wiring structure 140 is connected to the primary side water inlet and outlet 126 of the corresponding heat exchange device 120 through a fluid connector, and each secondary side water inlet and outlet 1412 is connected to the secondary side water inlet and outlet 127 of the corresponding heat exchange device 120 through a fluid connector. The shell 142 is connected to the shielding surface 141. By setting up a wiring structure 140, each primary water inlet and outlet 1411 included in the wiring structure 140 is connected to the primary water inlet and outlet 126 of the corresponding heat exchange device 120 through a fluid connector, and each secondary water inlet and outlet 1412 is connected to the secondary water inlet and outlet 127 of the corresponding heat exchange device 120 through a fluid connector, so that the multiple heat exchange devices 120 within the rack structure 110 of the heat exchange cabinet 100 provided by the present disclosure can be conveniently connected to the liquid cooling cabinet through the wiring structure 140, saving installation time. In actual applications, it is only necessary to connect the secondary water inlet and outlet 1412 of the wiring structure 140 included in the heat exchange cabinet 100 to the water inlet and outlet of the water circuit ring network of the computer room to achieve the connection between each heat exchange device 120 included in the heat exchange cabinet 100 of the present disclosure and each liquid cooling cabinet, which is simple to install and has high installation efficiency.

[0051] In practical applications, such as Figures 1 to 5As shown, the shape of the shielding surface 141 can be designed based on actual conditions. For example, the shape of the shielding surface 141 can be the same as the shape of the opening on the first side of the rack structure 110. In this case, the shielding surface 141 can completely cover the opening on the first side of the rack structure 110, making the first side of the rack structure 110 in a sealed state, improving the safety of the multiple heat exchange devices 120 located within the rack structure 110, and preventing the heat exchange devices 120 from operating abnormally or malfunctioning due to accidental contact during use. Of course, the shape of the shielding surface 141 can also be different from the shape of the opening on the first side of the rack structure 110. For example, when it is necessary to set a circuit connection structure at the opening on the first side of the rack structure 110, the shape of the shielding surface 141 can be designed based on the shape of the circuit connection structure to be set.

[0052] As a possible implementation, Figure 6 The structure diagram of the cable management structure provided according to the exemplary embodiment of the present disclosure is shown. Figure 2 .like Figures 1 to 6 As shown, the above-mentioned wiring structure 140 also includes a primary side inlet and outlet water loop 143 and a secondary side inlet and outlet water loop 144 arranged in the shell 142, wherein the primary side inlet and outlet water loop 143 can include a primary side inlet water loop 1431 and a primary side outlet water loop 1432; the secondary side inlet and outlet water loop 144 can include a secondary side inlet water loop 1441 and a secondary side outlet water loop 1442. The multiple primary side water inlets and outlets 1411 of the wiring structure 140 are connected to the primary side water inlet and outlet loop 143, and the multiple secondary side water inlets and outlets 1412 of the wiring structure 140 are connected to the secondary side water inlet and outlet loop 144. The primary side water inlet and outlet 126 of each heat exchange device 120 is connected to the primary side water inlet and outlet loop 143 through the corresponding primary side water inlet and outlet 1411 of the wiring structure 140, and the secondary side water inlet and outlet 127 of each heat exchange device 120 is connected to the secondary side water inlet and outlet loop 144 through the corresponding secondary side water inlet and outlet 1412 of the wiring structure 140. By setting up a primary side inlet and outlet water loop 143 and a secondary side inlet and outlet water loop 144, and the primary side inlet and outlet water port 126 of each heat exchange device 120 is connected to the primary side inlet and outlet water loop 143, and the secondary side inlet and outlet water port 127 of each heat exchange device 120 is connected to the secondary side inlet and outlet water loop 144, it can be avoided that when one heat exchange device 120 included in the heat exchange cabinet 100 has an abnormality and needs to be shut down, other heat exchange devices 120 can still work normally through another passage of the primary side inlet and outlet water loop 143 and another passage of the secondary side inlet and outlet water loop 144 without being affected by the shut down heat exchange device 120, thereby ensuring the stable operation of the liquid cooling heat exchange system and avoiding the problem of no backup safety risk of distributed heat exchange devices 120.

[0053] like Figures 1 to 6As shown, since the housing 142 includes the primary side water inlet and outlet loop 143 and the secondary side water inlet and outlet loop 144, the shape of the housing 142 can be designed according to the shape of the shielding surface 141 and the shapes of the primary side water inlet and outlet loop 143 and the secondary side water inlet and outlet loop 144 to ensure that the housing 142 can be connected to the shielding surface 141 and can accommodate the primary side water inlet and outlet loop 143 and the secondary side water inlet and outlet loop 144. For example, the shape of the housing 142 can be as follows Figure 5 The rectangular shape shown is not limited thereto.

[0054] In some alternative ways, such as Figures 1 to 6 As shown, the cable management structure 140 further includes multiple sets of primary water inlet and outlet branches 145 and multiple sets of secondary water inlet and outlet branches 146 disposed within the housing 142. Each primary water inlet and outlet 1411 of the cable management structure 140 is connected to the primary water inlet and outlet loop 143 via a corresponding set of primary water inlet and outlet branches 145, and each secondary water inlet and outlet 1412 of the cable management structure 140 is connected to the secondary water inlet and outlet loop 144 via a corresponding set of secondary water inlet and outlet branches 146. The multiple sets of primary water inlet and outlet branches 145 may include multiple sets of primary water inlet branches 1451 and multiple sets of primary water outlet branches 1452; and the multiple sets of secondary water inlet and outlet branches 146 may include multiple sets of secondary water inlet branches 1461 and multiple sets of secondary water outlet branches 1462. By providing multiple sets of primary-side inlet and outlet water branches 145 and multiple sets of secondary-side inlet and outlet water branches 146, it is convenient to connect multiple heat exchange devices 120 to the primary-side inlet and outlet water loop 143 and the secondary-side inlet and outlet water loop 144 respectively through the multiple sets of primary-side inlet and outlet water branches 145 and the multiple sets of secondary-side inlet and outlet water branches 146. It should be understood that the correspondence here means that among the multiple heat exchange devices 120, the primary-side inlet and outlet 126 of each heat exchange device 120 is connected to one set of the multiple sets of primary-side inlet and outlet water branches 145 included in the wiring structure 140, and the secondary-side inlet and outlet 127 of each heat exchange device 120 is connected to one set of the multiple sets of secondary-side inlet and outlet water branches 146 included in the wiring structure 140, and different heat exchange devices 120 have their primary-side inlet and outlet water branches 145 and their secondary-side inlet and outlet water branches 146 connected to different sets.

[0055] In some alternative ways, such as Figures 1 to 6As shown, the wiring structure 140 further includes multiple sets of first control valves (not shown) disposed within the housing 142, each set of first control valves being disposed on a corresponding set of primary-side inlet and outlet water branches 145. The wiring structure 140 further includes multiple sets of second control valves (not shown), each set of second control valves being disposed on a corresponding set of secondary-side inlet and outlet water branches 146. By providing a first control valve on each set of primary-side inlet and outlet water branches 145 and a second control valve on each set of secondary-side inlet and outlet water branches 146 of the wiring structure 140, if a heat exchange device 120 on a particular branch fails, the failed heat exchange device 120 can be isolated and repaired by closing the corresponding set of first and second control valves. At the same time, due to the annular arrangement of the primary side inlet and outlet water loop 143 and the secondary side inlet and outlet water loop 144, when any of the primary side inlet and outlet water branches 145 or the secondary side inlet and outlet water branches 146 fails, the annular arrangement of the primary side inlet and outlet water loop 143 and the secondary side inlet and outlet water loop 144 can both pass water without affecting the operation of the liquid cooling heat exchange system.

[0056] In actual applications, each group of the above-mentioned first control valves can be located on a corresponding group of primary side inlet and outlet water branches, or can be located respectively on a group of primary side inlet and outlet water branches and the loops on both sides connected to the primary side inlet and outlet water branches; each group of second control valves can be located on a corresponding group of secondary side inlet and outlet water branches, or can be located respectively on a group of secondary side inlet and outlet water branches and the loops on both sides connected to the secondary side inlet and outlet water branches.

[0057] In some alternative ways, such as Figures 1 to 6 As shown, the cable management structure 140 further includes a primary water inlet and outlet main line 147, one end of which extends into the interior of the housing 142 and communicates with the primary water inlet and outlet loop 143. The primary water inlet and outlet main line 147 may include a secondary water inlet main line 1471 and a secondary water outlet main line 1472. In this case, the primary water inlet loop 1431 communicates with the secondary water inlet main line 1471, and the primary water outlet loop 1432 communicates with the primary water outlet main line 1472. The cable management structure 140 further includes a secondary water inlet and outlet main line 148, one end of which extends into the interior of the housing 142 and communicates with the secondary water inlet and outlet loop 144. The secondary water inlet and outlet main lines 148 may include secondary water inlet main lines 1481 and secondary water outlet main lines 1482. In this case, the secondary water inlet loop 1441 is connected to the secondary water inlet main lines 1481, and the secondary water outlet loop 1442 is connected to the secondary water outlet main line 1482. Providing the primary water inlet and outlet main lines 147 and the secondary water inlet and outlet main lines 148 facilitates the connection of the cable management structure 140 to the water loop network in the machine room and to the outdoor cooling equipment, thereby improving installation efficiency.

[0058] In actual application, the primary side inlet and outlet water main lines included in the wiring structure can be connected to the water inlet and outlet of the outdoor cold source equipment, and the secondary side inlet and outlet water main lines included in the wiring structure can be connected to the water ring network in the computer room, so as to realize the quick connection of each heat exchange device of the heat exchange cabinet with the outdoor cold source equipment and the liquid cooling cabinet in the computer room, without having to quickly connect each heat exchange device with the outdoor cold source equipment and the liquid cooling cabinet in the computer room respectively, saving installation time and improving installation efficiency.

[0059] The aforementioned fluid connector may include a manually connected fluid connector. Of course, to improve installation efficiency, the fluid connector may also be a blind-plug type fluid connector. Furthermore, the electrical interface of the power module included in each heat exchange device may also be electrically connected to the power supply system provided in the data center computer room via a manually connected electrical connector. Of course, the electrical interface of the power module may also be electrically connected to the power supply system provided in the data center computer room via a blind-plug type electrical connector.

[0060] As a possible implementation, Figures 1 to 6 As shown, in order to improve installation efficiency, the heat exchange cabinet 100 further includes a plurality of blind-plug connectors (not shown in the figure), and each heat exchange device 120 is connected to the primary water inlet and outlet 1411 or the secondary water inlet and outlet 1412 of the corresponding cable management structure 140 through a corresponding blind-plug connector. By providing the blind-plug connector, the rack structure 110 of the heat exchange cabinet 100 carrying the heat exchange device 120 can be quickly connected to the water system pipeline of the cable management structure 140, further improving the installation efficiency of the workers. Specifically, the cable management structure 140 can pre-connect the water system pipeline connected to the heat exchange device 120. During installation, it is only necessary to install the rack structure 110 with the heat exchange device 120 on the cable management structure 140, or first fix the rack structure 110 and the cable management structure 140, and then push the heat exchange device 120 onto the support structure 130 of the rack structure 110 to achieve the installation of the heat exchange device 120 and the cable management structure 140. It should be understood that the blind-plug connector here can be a blind-plug type fluid connector. As for the model and manufacturer of the blind-plug type fluid connector, there is no restriction here. The commercially available blind-plug type fluid connectors that can meet the requirements of this disclosure are within the optional range.

[0061] In actual applications, the multiple heat exchange devices included in the above-mentioned heat exchange cabinet can be installed with blind plug female connectors, and the corresponding blind plug male connectors can be installed at the primary side water inlet and outlet or the secondary side water inlet and outlet of the wiring structure. During installation, the wiring structure can be pre-installed in the data center computer room, and the water loop network and the outdoor cold source can be connected. Then, multiple heat exchange devices that meet the cooling capacity requirements of the liquid cooling cabinet in the data center computer room are fixed in the rack structure, and the rack structure is manually pushed toward the wiring structure. The blind plug male connectors installed at the primary side water inlet and outlet or the secondary side water inlet and outlet of the wiring structure and the multiple heat exchange devices included in the rack structure can be installed with blind plug female connectors to achieve blind plug connection of the water system pipelines. Finally, the multiple heat exchange devices are powered by the power supply system set up in the data center computer room to achieve normal operation of the multiple heat exchange devices.

[0062] The present disclosure also provides a liquid cooling heat exchange system. Figure 7 FIG. 1 shows a schematic structural diagram of a liquid cooling heat exchange system according to an exemplary embodiment of the present disclosure. Figure 7 As shown, the liquid cooling heat exchange system 700 provided by the exemplary embodiment of the present disclosure includes a heat exchange cabinet 100, a cold source device (not shown in the figure), and multiple liquid cooling cabinets 710.

The primary inlet and outlet water main lines of the wiring structure included in the heat exchange cabinet 100 are connected to the water inlet and outlet of the cold source device, and the secondary inlet and outlet water main lines of the wiring structure are connected to the water inlet and outlet of each liquid cooling cabinet.

[0063] In practical applications, such as Figure 7 As shown, the heat exchange cabinet 100 included in the liquid cooling heat exchange system 700 can be connected to the cold source equipment and the water loop network 720 of the data center computer room as described above. Multiple liquid cooling cabinets 710 can be pre-connected to the water loop network 720. In this case, it is only necessary to ensure that the rack structure and cable management structure included in the heat exchange cabinet 100 are connected, and then power the multiple heat exchange devices through the power supply system set up in the data center computer room to achieve heat dissipation for the servers in the multiple liquid cooling cabinets 710.

[0064] The above-mentioned water ring network can be set up at the bottom of the floor of the data center computer room, and its specific location can be arranged according to the placement of the liquid cooling cabinets. A hose is left at the installation position of the cable management structure on the water ring network, and the hose can be connected to the secondary side water inlet and outlet at the bottom of the cable management structure by manual insertion or blind insertion. A branch pipe extends from the installation position of each liquid cooling cabinet corresponding to the water ring network, and the branch pipe is connected to the manifold of the liquid cooling cabinet. The low-temperature coolant is supplied to the heating unit through the manifold and the high-temperature coolant flowing back from the heating unit is collected. The water system pipeline in the water ring network is a ring pipeline, and water is passed in two directions to avoid failure of the pipeline in one direction. Water can be passed in the other direction without affecting the normal operation of the liquid cooling heat exchange system.
