Liquid cooling heat exchange device and cold plate type liquid cooling system

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202410387221.2 and application date April 1, 2024, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the field of data center cooling technology, and in particular to a liquid cooling heat exchange device and a cold plate liquid cooling system. Background Art

[0004] The rapid development of data centers and artificial intelligence technologies has placed higher demands on cooling systems for servers, chips, and other components. Cold plate liquid cooling has gradually become a major player in data center heat dissipation. However, current cold plate liquid cooling cabinets are connected through pipes, manifolds, and heat exchange units. The manifolds collect the high-temperature coolant after cooling the servers and funnel it to the heat exchange unit for cooling, which then continuously supplies cold water to the servers. The installation of various pipes, the circulation of coolant, and the constant plugging and unplugging of servers introduce impurities into the system. When these impurities accumulate to a certain level, they affect the entire liquid cooling system. Therefore, the pipes must be cleaned and decontaminated promptly, and the heat exchange unit must be shut down for cleaning. This severely impacts server operation and hinders business development and operations. Summary of the Invention

[0005] According to one aspect of the present disclosure, there is provided a liquid cooling heat exchange device, comprising: a de-duster, a heat exchanger, a bypass pipeline, a first controllable valve, a second controllable valve, and at least one circulating water pump;

[0006] The heat absorption side of the heat exchanger is arranged on the outdoor cold source pipeline, the heat release side of the heat exchanger, the at least one circulating water pump, the impurity remover and the first controllable valve are connected in series on the manifold pipeline, the first controllable valve is connected to the impurity remover, and the second controllable valve is arranged on the bypass pipeline, and the bypass pipeline is connected in parallel with the impurity remover and the first controllable valve.

[0007] According to another aspect of the present disclosure, a cold plate liquid cooling system is provided, which includes: a manifold, a cold plate device and a liquid cooling heat exchange device provided by the present disclosure, one end of the manifold is connected to the cold plate device, and the other end of the manifold is connected to the liquid cooling heat exchange device.

[0008] In one or more technical solutions provided in the embodiments of the present application, the liquid-cooled heat exchanger includes a de-duster, a heat exchanger, a first controllable valve, and at least one circulating water pump. Since the heat release side of the heat exchanger, the at least one circulating water pump, the de-duster, and the first controllable valve are connected in series on the manifold pipeline, and the first controllable valve is connected to the de-duster, the first controllable valve on the manifold pipeline is used to control the flow of coolant into the de-duster. When the first controllable valve is open, coolant can flow into the de-duster through the first controllable valve for de-duster removal. Furthermore, since the liquid-cooled heat exchanger also includes a bypass pipeline and a second controllable valve, the second controllable valve is provided on the bypass pipeline, and the bypass pipeline is connected in parallel with the de-duster and the first controllable valve. Therefore, when the de-duster in the liquid-cooled heat exchanger needs to be cleaned and maintained, the first controllable valve can be closed, and the second controllable valve, which is connected in parallel with the de-duster and the first controllable valve, can be opened to allow coolant to flow out through the bypass pipeline.

[0009] It can be seen that when the impurity remover needs cleaning and maintenance, the first control valve and the second control valve can be switched so that the coolant does not pass through the impurity removal component. At this time, the impurity removal component can be directly disassembled for cleaning and maintenance without shutting down the machine, which does not affect the operation of the liquid cooling heat exchange device and the server, thereby improving work efficiency and reducing energy consumption.

[0023] With the rapid development of data centers and artificial intelligence (AI), high-computing technologies like edge computing, AI training, and supercomputing are driving greater heat dissipation demands, placing higher demands on cooling systems for servers, chips, and other components. Traditional air cooling technology, commonly used in data centers, is increasingly approaching its limits, creating a huge demand for liquid cooling technology. The mainstream liquid cooling technologies on the market are cold plate and immersion cooling, with cold plate becoming the dominant technology due to its high efficiency and low cost.

[0024] Cold plate liquid cooling technology consists of a heat exchange unit, a cold plate assembly, a manifold, and related supporting piping and fittings. The cold plate assembly removes heat from the server's main heat dissipation components. The heat exchange unit is a key component in the cold plate liquid cooling system, which is divided into centralized and distributed types. The main components of the distributed heat exchange unit are the heat exchanger, circulating water pump, make-up water pump, and impurity remover. The impurity remover filters and removes impurities from the secondary water of the cold plate liquid cooling system. The pipes connected to the heat exchange unit include primary and secondary pipes. The secondary pipes are for server-side supply and return water, while the primary pipes are for outdoor cold source-side supply and return water. During heat exchange, the server-side return water exchanges heat with the outdoor cold source-side return water.

[0025] The inventors discovered that in current technology, most heat exchange units are in the form of complete cabinets, that is, the upper part is a power supply frame, and the lower part is a pipeline, heat exchanger and refrigerant pump, where the filter is connected to the pipeline. In the event of a failure, the entire unit needs to be shut down for replacement, and if a centralized heat exchange unit is shut down, it will affect the operation of multiple cabinets. At the same time, because the pipelines of the pumps in the heat exchange unit are not redundant, when there are many impurities in the solution, the impurities cannot be processed online, and the filter device is embedded in the heat exchange unit and cannot be replaced, resulting in failure of both pumps in the heat exchange unit. Therefore, replacing the filter still requires shutdown processing.

[0026] In order to overcome the above technical problems, the present disclosure provides a liquid-cooled heat exchange device, which realizes the switching of the liquid flow path of the return water pipeline of the manifold by setting a controllable valve assembly, so as to solve the problem that the current cold plate liquid cooling system needs to be shut down for maintenance and impurity removal during operation and maintenance, thereby reducing energy consumption and improving work efficiency.

[0027] Figure 1 shows a schematic diagram of the structure of a cold plate liquid cooling system according to an exemplary embodiment of the present disclosure. As shown in Figure 1 , cold plate liquid cooling system 100 includes a manifold 110, a cold plate assembly 120, and a liquid-cooled heat exchanger 130. One end of manifold 110 is connected to cold plate assembly 120, and the other end of manifold 110 is connected to liquid-cooled heat exchanger 130.

[0028] For example, by arranging the cold plate device 120 above the main heat-generating elements in the server, when the cold plate liquid cooling system 100 is running, the low-temperature coolant flows out of the liquid-cooled heat exchange device 130, enters the water supply riser of the manifold 110, is distributed to each server node by the water supply riser of the manifold 110, and then enters the cold plate device 120, exchanges heat with the main heat-generating elements in the cold plate device 120, absorbs the heat of the main heat-generating elements, and turns into high-temperature coolant and flows out of each server node. The outflowing high-temperature coolant enters the return water riser of the manifold 110, passes through the return water riser of the manifold 110 and returns to the liquid-cooled heat exchange device 130, where it is cleaned and heat-exchanged back to low-temperature coolant, completing the cycle.

[0029] Figure 2 shows a schematic diagram of the structure of a liquid-cooled heat exchange device according to an exemplary embodiment of the present disclosure. As shown in Figure 2, the liquid-cooled heat exchange device provided by the present disclosure includes: a de-duster 210, a heat exchanger 220, a bypass line 230, a first controllable valve 211, a second controllable valve 231, and at least one circulating water pump 240.

[0030] As shown in Figure 2, the heat absorption side of the above-mentioned heat exchanger 220 is arranged on the outdoor cold source pipeline 250. Specifically, the first heat absorption side interface 221 of the heat exchanger 220 is connected to the outdoor cold source return pipeline 251, and the second heat absorption side interface 222 of the heat exchanger 220 is connected to the outdoor cold source supply pipeline 252, so that the high-temperature coolant can exchange heat with the outdoor cold source in the heat exchanger 220, and after becoming low-temperature coolant, continue to flow into the server to absorb heat from the main heating components of each server node in the server.

[0031] As shown in Figure 2, the heat release side of the heat exchanger 220, at least one circulating water pump 240, the impurity remover 210, and the first controllable valve 211 are connected in series to the manifold pipeline 260. The first controllable valve 211 is connected to the impurity remover 210, and the second controllable valve 231 is provided on the bypass pipeline 230, which is connected in parallel with the impurity remover 210 and the first controllable valve 211. It should be noted that the first controllable valve 211 and the second controllable valve 231 can be opened and closed manually or under the control of a controller.

[0032] When the first controllable valve and the second controllable valve are opened and closed manually, the upper cover of the cabinet can be opened and the worker can manually adjust the opening and closing of the first controllable valve and the second controllable valve.

[0033] When the above-mentioned first controllable valve and second controllable valve are opened and closed by the controller 290 as shown in Figure 2, the controller 290 can send control signals to the first controllable valve 211 and the second controllable valve 231, and the first controllable valve 211 and the second controllable valve 231 receive the corresponding control signals and open or close according to the corresponding control signals.

[0034] Exemplarily, the controller may be an integrated circuit comprising a microcontroller unit (MCU). The microcontroller may include a central processing unit (CPU), a read-only memory (ROM), a random access memory (RAM), a timing module, an analog-to-digital converter (A / D converter), and a number of input / output ports. Of course, the controller may also be implemented as other integrated circuits, such as application-specific integrated circuits (ASICs) or field-programmable gate arrays (FPGAs).

[0035] Figure 3 shows a second schematic structural diagram of a liquid-cooled heat exchange device according to an exemplary embodiment of the present disclosure. As shown in Figures 2 and 3, the position of the impurity remover 210 can be in two situations: first, the impurity remover 210 is located between the return water pipe 261 of the manifold and the at least one circulating water pump 240; second, the impurity remover 210 is located between the heat exchanger 220 and the water supply pipe 262 of the manifold.

[0036] As shown in Figure 2, when the above-mentioned impurity remover 210 is located between the return pipe 261 of the manifold and the at least one circulating water pump 240, the inlets of the first controllable valve 211 and the second controllable valve 231 are both connected to the return pipe 261 of the manifold, the outlet of the first controllable valve 211 is connected to the inlet of the at least one circulating water pump 240 via the impurity remover 210, the outlet of the second controllable valve 231 is connected to the inlet of the at least one circulating water pump 240, the outlet of the at least one circulating water pump 240 is connected to the first heat release side interface 223 of the heat exchanger 220, and the second heat release side interface 224 of the heat exchanger 220 is connected to the water supply pipe 262 of the manifold.

[0037] As shown in Figure 3, when the above-mentioned impurity remover 210 is located between the heat exchanger 220 and the water supply pipe 262 of the manifold, the return pipe 261 of the manifold is connected to the inlet of at least one circulating water pump 240, and the outlet of at least one circulating water pump 240 is connected to the first heat release side interface 223 of the heat exchanger 220. The second heat release side interface 224 of the heat exchanger 220 is respectively connected to the inlets of the first controllable valve 211 and the second controllable valve 231. The outlet of the first controllable valve 211 is connected to the water supply pipe 262 of the manifold via the impurity remover 210, and the outlet of the second controllable valve 231 is connected to the water supply pipe 262 of the manifold.

[0038] In summary, the liquid-cooled heat exchange device includes a de-duster, a heat exchanger, a first controllable valve, and at least one circulating water pump. Since the heat release side of the heat exchanger, at least one circulating water pump, the de-duster, and the first controllable valve are connected in series on the manifold pipeline, and the first controllable valve is connected to the de-duster, the first controllable valve on the manifold pipeline is used to control the flow of coolant into the de-duster. When the first controllable valve is in an open state, coolant can flow into the de-duster through the first controllable valve for de-duster removal. Furthermore, since the liquid-cooled heat exchange device also includes a bypass pipeline and a second controllable valve, the second controllable valve is provided on the bypass pipeline, and the bypass pipeline is connected in parallel with the de-duster and the first controllable valve. That is, when the de-duster in the liquid-cooled heat exchange device needs to be cleaned and maintained, the first controllable valve can be closed, and the second controllable valve connected in parallel with the de-duster and the first controllable valve can be opened, so that the coolant can flow out through the bypass pipeline.

[0039] It can be seen that when the impurity remover needs cleaning and maintenance, the first control valve and the second control valve can be switched so that the coolant does not pass through the impurity removal component. At this time, the impurity removal component can be directly disassembled for cleaning and maintenance without shutting down the machine, which does not affect the operation of the liquid cooling heat exchange device and the server, thereby improving work efficiency and reducing energy consumption.

[0040] For example, as shown in Figures 2 and 3, when the impurity remover 210 needs to be disassembled, a connector 212 can be provided at the water inlet and outlet of the impurity remover 210. When the impurity remover 210 needs to be cleaned or replaced, the connector 212 can be manually opened, and the U-shaped pipeline including the impurity remover 210 can be directly disassembled and replaced, thereby reducing leakage of coolant in the pipeline and improving the replacement efficiency of the impurity remover 210. It should be understood that the connector 212 here can be a quick-change connector, for example, a ball valve-type quick-change connector, etc., but is not limited to this.

[0041] As a possible implementation, as shown in Figures 2 and 3 , the liquid-cooled heat exchange device further includes multiple first blind-plug connectors 270 . At least one circulating water pump 240 and the impurity remover 210 are each connected in series to the manifold pipe 260 via corresponding first blind-plug connectors 270 . It should be understood that the first blind-plug connectors 270 may be blind-plug fluid connectors. The provision of the first blind-plug connectors 270 facilitates rapid removal and replacement of the impurity remover 210 and the at least one circulating water pump 240, thereby improving work efficiency.

[0042] As shown in Figures 2 and 3, when the above-mentioned impurity remover 210 is located between the return water pipeline 261 of the manifold and the at least one circulating water pump 240, the first heat release side interface 223 of the heat exchanger 220 is connected to the outlet of the at least one circulating water pump 240 through the corresponding first blind plug joint 270, and the inlet of the at least one circulating water pump 240 is respectively connected to the first controllable valve 211 and the second controllable valve 231 through the corresponding first blind plug joint 270. It should be understood that since the liquid cooling heat exchange device of the present disclosure has multiple first blind plug joints 270, the correspondence here refers to the provision of a first blind plug joint 270 at the inlet pipeline of the at least one circulating water pump 240. At this time, it is considered that the first blind plug joint 270 provided at the inlet pipeline of the at least one circulating water pump 240 is the first blind plug joint 270 corresponding to the inlet pipeline of the at least one circulating water pump 240. Similarly, the provision of a first blind plug joint 270 at the outlet pipeline of the at least one circulating water pump 240 can be considered as the provision of a first blind plug joint 270 at the outlet pipeline of the at least one circulating water pump 240. The first blind plug joint 270 at the outlet pipe of the impurity remover 200 is the first blind plug joint 270 corresponding to the outlet pipe of at least one circulating water pump 240, and the inlet pipe and outlet pipe of the impurity remover 210 are respectively provided with a first blind plug joint 270. It can be considered that the first blind plug joint 270 provided at the inlet pipe of the impurity remover 210 is the first blind plug joint 270 corresponding to the inlet pipe of the impurity remover 210, and the first blind plug joint 270 provided at the outlet pipe of the impurity remover 210 is the first blind plug joint 270 corresponding to the outlet pipe of the impurity remover 210.

[0043] When at least one circulating water pump or impurity remover needs to be repaired or replaced, due to the complex pipe connections in the cabinet of the liquid-cooled heat exchange device, the staff will spend a lot of time in the disassembly and installation process, which reduces work efficiency. Therefore, the water channel connector of at least one circulating water pump or impurity remover can be replaced with a first blind plug connector, that is, a blind plug type fluid connector, so that when at least one circulating water pump or impurity remover is in operation and maintenance, it can be directly unplugged, and when it needs to be installed, it can be directly plugged in, thereby improving the work efficiency of the staff. It should be understood that the first blind plug connector here only needs to meet the requirements of water flow when the male and female heads are plugged together, and the pipeline can be closed when the male and female heads are disconnected. The first blind plug connector can be a quick-change connector or other various forms of fluid connectors, and is not limited here. The first blind plug connector can be set on the inner wall of the liquid-cooled heat exchange device along the movement direction of at least one circulating water pump when plugging and unplugging.

[0044] As one possible implementation, as shown in Figures 2 and 3 , coolant loss may occur during the operation of the liquid-cooled heat exchanger. In this case, the liquid-cooled heat exchanger may further include a water supply pump 280 connected to the water supply pipeline, with the outlet of the water supply pump 280 connected to the inlet of at least one circulating water pump 240. The provision of the water supply pump 280 allows the liquid-cooled heat exchanger to be replenished with coolant, ensuring sufficient coolant in the pipelines of the liquid-cooled heat exchanger, thereby maintaining the cooling effect of the liquid-cooled heat exchanger.

[0045] In some optional embodiments, as shown in Figures 2 and 3, the liquid cooling heat exchange device further includes a second blind-plug connector 281, through which the outlet of the water supply pump 280 is connected to at least one circulating water pump 240. The provision of the second blind-plug connector 281 facilitates quick disassembly and assembly of the water supply pump 280 during maintenance or replacement, thereby improving the work efficiency of the staff.

[0046] For example, the inlet of the make-up water pump can be connected to the make-up water pipeline to transport the coolant in the make-up water pipeline to the circulation pipeline within the liquid-cooled heat exchange device. The outlet of the make-up water pump can be connected to the circulation pipeline of at least one circulating water pump. In this case, the connection between the outlet of the make-up water pump and the at least one circulation pipeline can be limited based on the position of the at least one circulating water pump.

[0047] For example, as shown in Figures 2 and 3, when the liquid-cooled heat exchange device includes two circulating water pumps, the two circulating water pumps may include a main circulating water pump 241 and an auxiliary circulating water pump 242, wherein the main circulating water pump 241 is a circulating water pump located below the make-up water pump 280, and the auxiliary circulating water pump 242 is a circulating water pump located above the make-up water pump 280. When the main circulating water pump 241 is in operation, the outlet of the make-up water pump 280 can be connected to the outlet of the main circulating water pump 241. When the auxiliary circulating water pump 242 is in operation, the outlet of the make-up water pump 280 can be connected to the inlet of the auxiliary circulating water pump 242.

[0048] As a possible implementation, as shown in Figures 2 and 3, the liquid-cooled heat exchange device further includes a controller 290, which is signal-connected to the first controllable valve 211, the second controllable valve 231, and at least one circulating water pump 240. The controller 290 can be configured to control the switching of at least one circulating water pump 240 to ensure that the cold plate liquid cooling system 100 can continue to operate when one of the circulating water pumps 240 requires maintenance. The controller 290 can also switch the path of the coolant flowing through the impurity remover 210 by controlling the first controllable valve 211 and the second controllable valve 231. This ensures that when the impurity remover 210 needs to be cleaned or replaced, the coolant path can be switched so that the coolant flows out through the bypass pipe instead of passing through the impurity remover 210, thereby improving the replacement efficiency of the impurity remover 210.

[0049] For example, when the above-mentioned liquid-cooled heat exchange device includes two circulating water pumps, the two circulating water pumps may include a main circulating water pump and an auxiliary circulating water pump. When the main circulating water pump needs operation and maintenance, the main circulating water pump connected to the circulation pipeline in the liquid-cooled heat exchange device can be switched to the auxiliary circulating water pump through the controller, so that the high-temperature coolant from the return pipeline of the manifold can flow into the auxiliary circulating water pump to ensure that the main circulating water pump will not affect the normal operation of the cold plate liquid cooling system during operation and maintenance.

[0050] In some optional embodiments, as shown in Figures 2 and 3, the liquid cooling heat exchange device further includes a power supply assembly 300 and an electrical connector 310. The power supply assembly 300 is electrically connected to at least one circulating water pump 240 and a water supply pump 280 via the electrical connector 310. The provision of the electrical connector 310 enables quick plugging and unplugging of the at least one circulating water pump 240 and the water supply pump 280 from the power supply assembly 300, thereby improving work efficiency.

[0051] For example, when at least one circulating water pump is undergoing maintenance, the controller can be used to first control the at least one circulating water pump to switch to another standby circulating water pump in the liquid-cooled heat exchange device, and then the at least one circulating water pump can be unplugged from the corresponding first blind-plug connector and electrical connector to achieve rapid disassembly of the at least one circulating water pump. When the at least one circulating water pump needs to be installed, the blind-plug connector and electrical connector of the at least one circulating water pump can be simultaneously blind-plugged to the corresponding first blind-plug connector and electrical connector located in the liquid-cooled heat exchange device to achieve rapid installation of the at least one circulating water pump. At this time, the first blind-plug connector and electrical connector connected to the at least one circulating water pump in the liquid-cooled heat exchange device can be located on the same horizontal plane.

[0052] For another example, when the make-up water pump is undergoing maintenance, the make-up water pump can be removed from the corresponding second blind-plug connector and electrical connector to quickly disassemble the make-up water pump. When the make-up water pump needs to be installed, the make-up water pump's blind-plug connector and electrical connector can be simultaneously blind-plugged with the corresponding second blind-plug connector and electrical connector located within the liquid-cooled heat exchanger, allowing for quick installation of the make-up water pump. In this case, the second blind-plug connector and electrical connector connected to the make-up water pump within the liquid-cooled heat exchanger can be located on the same horizontal plane.

[0053] In some optional embodiments, in order to improve work efficiency, at least one circulating water pump or make-up water pump can be inspected while powered on to determine whether at least one circulating water pump or make-up water pump needs to be replaced. At this time, in order to ensure that the power supply component can continuously supply power to at least one circulating water pump or make-up water pump when the at least one circulating water pump or make-up water pump is unplugged, the above-mentioned liquid cooling heat exchange device may also include a tape-shaped wire, and the electrical connector is electrically connected to the tape-shaped wire.

[0054] In practical applications, one or both ends of the tape-shaped wire are connected to an electrical connector. One end of the tape-shaped wire with the electrical connector is connected to at least one circulating water pump, and the other end is connected to the power supply assembly. When the at least one circulating water pump is undergoing maintenance, the tape-shaped wire will be stretched as the at least one circulating water pump moves away from the cabinet. At this time, since the at least one circulating water pump and the power supply assembly are still connected, the at least one circulating water pump can be directly repaired, thereby improving the efficiency of the at least one circulating water pump. When it is determined that the at least one circulating water pump needs to be replaced, a staff member can manually separate the electrical connector of the tape-shaped wire from the electrical connector of the at least one circulating water pump. At this time, the electrical connector of the end of the tape-shaped wire connected to the at least one circulating water pump will be retracted into the liquid-cooled heat exchange device by the tape-shaped wire. When the at least one circulating water pump is replaced, the at least one circulating water pump can be pushed into the liquid-cooled heat exchange device so that the first blind-plug connector and electrical connector corresponding to the at least one circulating water pump can be blind-plugged with the blind-plug connector and electrical connector of the tape-shaped wire in the corresponding circulation pipeline. It should be understood that the connection between the power supply assembly and the server can also be made using a tape measure-shaped wire, so that when the liquid cooling heat exchange device is disconnected from the server, the liquid cooling heat exchange device is still in normal operation.

[0055] In some optional embodiments, FIG4 shows a schematic structural diagram of a liquid-cooled heat exchange device with a supporting structure according to an exemplary embodiment of the present disclosure. As shown in FIG4 , the liquid-cooled heat exchange device further includes a supporting structure 410 (shaded portion in the figure), within which the impurity remover 210, the make-up water pump 280, and the at least one circulating water pump 240 are all disposed. By providing the supporting structure 410 to support the impurity remover 210, the make-up water pump 280, and the at least one circulating water pump 240, a modular design of the impurity remover 210, the make-up water pump 280, and the at least one circulating water pump 240 can be achieved, ensuring rapid disassembly of the impurity remover 210, the make-up water pump 280, and the at least one circulating water pump 240. The modular impurity remover 210, the make-up water pump 280, or the at least one circulating water pump 240 can be maintained independently without removing the liquid-cooled heat exchange device, thereby preventing the impurity remover 210, the make-up water pump 280, or the at least one circulating water pump 240 from affecting the cold plate liquid cooling system 100 when maintenance is required.

[0056] In some optional embodiments, the above-mentioned supporting structure may include multiple detachable structures, each detachable structure has a storage space, and the impurity remover, the water supply pump and the at least one circulating water pump are located in the storage space of the corresponding detachable structure. It is understandable that in order to ensure that the impurity remover, the water supply pump and the at least one circulating water pump can be taken out from the detachable structure, the above-mentioned detachable structure may have an opening or an openable cover. In order to ensure that the first blind plug connector, the second blind plug connector or the electrical connector corresponding to each detachable structure can be disconnected or connected at the same time when the detachable structure is pulled out or inserted, the first blind plug connector, the second blind plug connector or the electrical connector located in each detachable structure can be located on the same plane. The positional relationship between the detachable structures that carry the impurity remover, the water supply pump or the at least one circulating water pump can be designed according to actual conditions and is not limited here.

[0057] For example, when the positional relationship between the above-mentioned detachable structures carrying the impurity remover 210, the make-up water pump 280 or at least one circulating water pump 240 is the positional relationship shown in Figure 4, the liquid-cooled heat exchange device includes a main circulating water pump 241 (located below the make-up water pump 280), an auxiliary circulating water pump 242 (located above the make-up water pump 280), the make-up water pump 280, the impurity remover 210, the heat exchanger 220 and the power supply assembly 300. When the pulling and pulling direction of the detachable structure carrying the impurity remover 210, the water supply pump 280 or at least one circulating water pump 240 is the same as the water flow direction of the return pipe 261 of the manifold, since the impurity remover 210 is located on the right side of the main circulating water pump 241 and is blocked by the main circulating water pump 241, when it is necessary to maintain the impurity remover 210, the controller 290 can be used to control the connected circulating water pump in the liquid cooling heat exchange device to switch to the auxiliary circulating water pump 242, and then the main circulating water pump 241 can be pulled out along the preset pulling and pulling direction, so that the impurity remover 210 located on the right side of the main circulating water pump 241 leaks out. At this time, the impurity remover 210 can be pulled out along the preset pulling and pulling direction to perform maintenance on the impurity remover 210. It should be understood that the pulling and pulling direction here can be designed according to actual conditions and is not limited here.

[0058] For another example, when the at least one circulating water pump needs to be replaced, the detachable structure corresponding to the at least one circulating water pump can be pulled out from the liquid-cooled heat exchange device. At this time, since the first blind plug connector and the electrical connector corresponding to the inlet and outlet of the at least one circulating water pump are located on the same plane, when the detachable structure corresponding to the at least one circulating water pump is pulled out from the liquid-cooled heat exchange device, the first blind plug connector and the electrical connector corresponding to the at least one circulating water pump can be disconnected at the same time. In order to ensure that the electrical connector can remain connected, the electrical connector can be electrically connected to the tape-shaped wire. At this time, the tape-shaped wire can be located in the liquid-cooled heat exchange device or in the detachable structure corresponding to the first blind plug connector. It should be understood that the replacement method of the above-mentioned water supply pump can refer to the relevant description of the at least one circulating water pump and will not be repeated here.

[0059] In some optional embodiments, the above-mentioned supporting structure may further include a shell and a plurality of box bodies arranged in the shell, the shell having a plurality of pull-out openings so that the plurality of box bodies located in the shell can be plugged in and out along the extension direction of the pull-out openings. Each box body has a storage space, and the impurity remover, the water supply pump and the at least one circulating water pump are located in the storage space of the corresponding box body. It should be understood that in order to ensure that the first blind plug connector, the second blind plug connector or the electrical connector corresponding to each box body can be disconnected or connected at the same time when the box body is pulled out or inserted into the shell, the first blind plug connector, the second blind plug connector or the electrical connector located in each detachable structure can be located on the same plane. The correspondence here means that the impurity remover, the water supply pump and the at least one circulating water pump are respectively located in different box bodies. The shape of the box body can be designed according to actual conditions and is not limited here. For example, the shape of the box body can be a regular rectangular parallelepiped, or it can be other irregular shapes, etc. The positional relationship between the box bodies carrying the impurity remover, the water supply pump or the at least one circulating water pump can be designed according to actual conditions and is not limited here.

[0060] In practical applications, the box body may be a drawer, with each drawer located at a corresponding position within the box body, and the impurity remover, the make-up water pump, and the at least one circulating water pump located within the corresponding drawer. The provision of drawers allows the impurity remover, the make-up water pump, and the at least one circulating water pump within the liquid-cooled heat exchanger to be modularized. This ensures that during operation and maintenance of the liquid-cooled heat exchanger, the modular impurity remover, the make-up water pump, and the at least one circulating water pump can be quickly disassembled and assembled with the circulating piping within the liquid-cooled heat exchanger, enabling rapid replacement of the at least one circulating water pump and the impurity remover, thereby improving work efficiency.

[0061] The drawer can be a covered drawer or an uncovered drawer, without limitation. The shape of the drawer can be adjusted based on actual application. For example, the drawer can be a regular square drawer or other irregular shapes. It should be understood that in order to ensure that the debris remover located in the drawer can be blind-plugged to the second blind-plug connector and that the at least one circulating water pump can be blind-plugged to the first blind-plug connector, through holes should be provided at corresponding positions in the drawer.

[0062] For example, when the above-mentioned liquid-cooled heat exchange device includes two circulating water pumps and the main circulating water pump needs to be repaired, the controller can be used to control the corresponding valve to send the high-temperature coolant in the circuit from the manifold to the auxiliary circulating water pump to avoid the impact of the main circulating water pump repair on the system. At this time, the tape-shaped wire connected to the electrical connector of the main circulating water pump can be located in the drawer containing the circulating water pump. When the drawer containing the circulating water pump moves in a direction away from the liquid-cooled heat exchange device, the first blind plug connector connected to the circulating water pump is pulled out, and the tape-shaped wire is stretched as the circulating water pump moves, while the electrical connector remains connected. When the circulating water pump needs to be replaced, the electrical connector can be manually separated, and the male connector at the circulating water pump will retract to the plane where the first blind plug connector is located. When the tape-shaped wire connected to the electrical connector of the circulating water pump that needs to be repaired is located outside the drawer containing the circulating water pump, the electrical female connector of the tape-shaped wire will retract into the plane where the first blind plug connector is located, so as to realize convenient maintenance of the circulating water pump. During the maintenance of one of the circulating water pumps, the other circulating water pump can continue to work to ensure the normal operation of the cold plate liquid cooling system. It should be understood that the connection method of the electrical connector of the make-up water pump and the tape-shaped wire can refer to the relevant description of the circulating water pump above and will not be repeated here.

[0063] FIG5 illustrates a schematic structural diagram of a drawer with a handle according to an exemplary embodiment of the present disclosure. As shown in FIG5 , when a worker needs to inspect a debris remover, a water supply pump, and at least one circulating water pump, they need to pull out the drawer 420 containing the debris remover, the water supply pump, or the at least one circulating water pump, thereby disconnecting the at least one circulating water pump or the debris remover from its corresponding first blind-plug connector, or disconnecting the water supply pump from its corresponding second blind-plug connector. To facilitate operation, a built-in handle 421 can be provided on the drawer 420, allowing the worker to pull out the corresponding drawer 420 using the built-in handle 421.

[0064] During the operation of the cold plate liquid cooling system, the drawer may slide, causing at least one circulating water pump or impurity remover in the drawer to be disconnected from its corresponding first blind plug connector, or the water supply pump to be disconnected from its corresponding second blind plug connector, thereby affecting the normal operation of the cold plate liquid cooling system.

[0065] To prevent this phenomenon, the liquid-cooled heat exchanger can also include a securing device, which can be positioned at the drawer opening of the housing to secure the drawer and prevent it from sliding out and affecting the normal operation of the cold plate liquid cooling system. For example, the securing device can be a retaining plate rotatably connected to the drawer opening of the housing. In another example, the securing device can be a door panel that is movably connected to the opening of the housing. The door panel can be locked to secure the drawer within the housing; when the drawer needs to be withdrawn, the corresponding door panel can be opened.

[0066] In some optional embodiments, the supporting structure may further include a housing having multiple independent spaces, each of which has at least one openable sidewall, such that each independent space is connected to the outside world when the sidewall is opened. The impurity remover, the water supply pump, and at least one circulating water pump are located within the corresponding independent spaces. It should be understood that the positional relationship between the independent spaces supporting the impurity remover, the water supply pump, or the at least one circulating water pump can be designed based on actual conditions and is not limited here.

[0067] In actual application, when at least one side wall of the above-mentioned independent space is in an open state, the impurity remover, water supply pump or at least one circulating water pump located in the independent space is exposed, which is convenient for maintenance by staff. At this time, the first blind plug connector, the second blind plug connector or the electrical connector that are blindly connected to the impurity remover, water supply pump or at least one circulating water pump can be located on the inner wall of the corresponding independent space. It should be understood that the specific position of the first blind plug connector, the second blind plug connector or the electrical connector can be determined according to the plug-in and unplugging direction of the impurity remover, water supply pump or at least one circulating water pump, and is not limited here. By setting a plurality of independent spaces in the shell of the liquid-cooled heat exchange device, and placing the impurity remover, water supply pump or at least one circulating water pump in the corresponding independent space, the operation and maintenance of the impurity remover, water supply pump or at least one circulating water pump can be facilitated.

[0068] Exemplarily, when the above-mentioned impurity remover needs to be replaced, the side wall of the independent space where the impurity remover is located can be opened. The opening method of the side wall of the independent space can be a pull-out method, or an opening and closing method when the hinge is connected, etc., but is not limited to this. After opening the side wall of the independent space, the staff can remove and replace the impurity remover from the opening of the independent space without moving other components of the liquid cooling heat exchange device. The replacement method of at least one circulating water pump and the water supply pump can refer to the relevant description of the above-mentioned impurity remover, which will not be repeated here. At this time, the first blind plug connector connected to the impurity remover can be a ball valve-shaped quick-change connector, which has a very small plug-in and pull-out force and can be manually connected and plugged in. The ball valve-shaped quick-change connector can be divided into two parts, a male head and a female head. There is a ball valve in each of the male and female heads. It is configured that when the male and female heads are connected, the ball valves on the male and female heads can be opened. When the male and female heads are not connected, the ball valve cannot be opened, and the male and female heads can only be separated when the ball valves on the male and female heads are closed.

Accordingly, this specification and the drawings are merely illustrative of the present disclosure as defined by the appended claims and are deemed to cover any and all modifications, variations, combinations or equivalents within the scope of the present disclosure.
