[0048] With the rapid development of cloud computing, big data, artificial intelligence and other technologies, data centers need better heat dissipation. Data centers include multiple machine buildings, each of which has multiple machine rooms, and each machine room has multiple cabinets. Figure 1 As shown, the present application provides a centralized liquid cooling heat exchange unit 100 for heat dissipation in a data center. In particular, the centralized liquid cooling heat exchange unit 100 can adjust the temperature of the servers in the cabinets of the data center. The centralized liquid cooling heat exchange unit 100 evenly distributes the heat exchange medium to the servers, achieves efficient heat dissipation, and ensures the stable operation of the equipment in the data center. The centralized liquid cooling heat exchange unit 100 is used for multiple liquid cooling cabinets. Optionally, 2 (one for use and one for backup) or 4 (2 for use and 2 for backup) centralized liquid cooling heat exchange units 100 can be installed in a computer room. Each centralized liquid cooling heat exchange unit 100 can provide normal operation for 20 liquid cooling cabinets.

[0049] The centralized liquid cooling heat exchange unit 100 includes a heat exchange module 120 and a power module 130. The heat exchange module 120 is configured as an integrated module, and the power module 130 is configured as an integrated module. The various heat exchange components in the heat exchange module 120 are integrated together. The various power components in the power module 130 are integrated together. In an optional embodiment, the driving component of the power module 130 is constructed as an independent modular decoupled water pump. The operator can directly remove the heat exchange module 120 or the power module 130 without being affected by other pipelines or components, which is convenient for maintenance.

[0050] Specifically, the cabinet includes a server and a heat dissipation mechanism 201, and the heat dissipation mechanism 201 is used to adjust the temperature of the server. The server is provided with a heating element, such as an electronic element such as a chip. The heat dissipation mechanism 201 can adjust the temperature of the heating element. For example, the heat dissipation mechanism 201 can reduce the temperature of the heating element to play a heat dissipation role. The centralized liquid cooling heat exchange unit 100 can adjust the temperature of the heat exchange medium of the heat dissipation mechanism 201.

[0051] The centralized liquid-cooled heat exchange unit 100 dissipates heat for the heat exchange medium on the primary side, and the heat dissipation mechanism 201 dissipates heat for the heat exchange medium on the secondary side. A first heat exchange medium is provided in the centralized liquid-cooled heat exchange unit 100, and the first heat exchange medium exchanges heat with the external cold source 200. The first heat exchange medium may be a coolant. The external cold source 200 may be, for example, cooling water, air conditioning, etc. The centralized liquid-cooled heat exchange unit 100 can transfer the coldness of the external cold source 200 to the cabinet, and then dissipate heat to the electronic equipment (such as a heating element) through the liquid-cooled cabinet. The external cold source 200 can take away the heat of the first heat exchange medium to reduce the temperature of the first heat exchange medium.

[0052] A second heat exchange medium is provided in the heat dissipation mechanism 201, and the second heat exchange medium performs heat exchange with the heating element. The first heat exchange medium from the centralized liquid cooling heat exchange unit 100 can also perform heat exchange with the second heat exchange medium in the heat dissipation mechanism 201. The first heat exchange medium can adjust the temperature of the second heat exchange medium. Preferably, the temperature of the first heat exchange medium in the heat dissipation mechanism 201 is lower than the temperature of the second heat exchange medium, and the second heat exchange medium can dissipate heat in the heat dissipation mechanism 201 to reduce the temperature. The second heat exchange medium after the temperature is reduced flows to the cold plate in the server of the cabinet. The second heat exchange medium exchanges heat with the heating element in the cold plate, takes away the heat of the heating element, and reduces the temperature of the heating element.

[0053] The centralized liquid cooling heat exchange unit 100 is constructed as a rectangular parallelepiped structure. The centralized liquid cooling heat exchange unit 100 includes a cabinet 110, and the cabinet 110 is constructed to be hollow. The cabinet 110 is an external box body. The cabinet 110 can be constructed as a hexahedron structure. Preferably, the cabinet 110 is constructed as a hollow rectangular parallelepiped structure. Thus, the cabinet 110 can provide a protection function for each module. In addition, the installation position of each module is reserved in the cabinet 110, and the pipeline position is reasonably arranged.

[0054] The heat exchange module 120 is detachably installed in the cabinet 110. The heat exchange module 120 is used to adjust the temperature of the heat exchange medium of the heat dissipation mechanism 201. The heat exchange module 120 can adjust the temperature of the server chip. The heat exchange module 120 is configured as an integrated module. The heat exchange module 120 includes a plate heat exchanger and a supporting component of the plate heat exchanger. The first heat exchange medium can perform heat exchange with the external cold source 200 in the heat exchange module 120. The various heat exchange components in the heat exchange module 120 are integrated together. The various components in the heat exchange module 120 are integrated together and are constructed in a disassembled form. A space for convenient installation is reserved in the cabinet 110 to facilitate the installation and disassembly of the heat exchange module 120.

[0055] The centralized liquid cooling heat exchange unit 100 further includes a power module 130, which is detachably mounted in the cabinet 110. The power module 130 is used to drive the heat exchange medium flowing through the heat exchange module 120. The power module 130 is configured as an integrated module. The components in the power module 130 are integrated together and are constructed in a disassembled form. A space for convenient installation is reserved in the cabinet 110 to facilitate the installation and disassembly of the power module 130.

[0056] To facilitate maintenance, Figure 4 As shown, the power module 130 includes a connecting wall 132, and the connecting wall 132 is provided with a water inlet 133, a water outlet 134 and an electrical connection component 135. The water inlet 133, the water outlet 134 and the electrical connection component 135 are all located on the same surface of the power module 130. The first heat exchange medium enters the power module 130 through the water inlet 133. The water outlet 134 is connected to the heat exchange module 120. The first heat exchange medium from the power module 130 is discharged through the water outlet 134. The first heat exchange medium from the power module 130 enters the heat exchange module 120. The electrical connection component 135 is used to electrically connect to the cabinet. Optionally, the water inlet 133 of the power module 130 in the power module 130 can be configured as a blind plug-in type fluid connector or a hand plug-in type fluid connector. The water outlet 134 can be configured as a blind plug-in type fluid connector or a hand plug-in type fluid connector. As a result, it is possible to eliminate the need to install a locking device on the cabinet 110. For example, as Figure 2 As shown, the cabinet 110 includes a first door 111, and the first door 111 faces the cabinet. No locking device is required to be installed on the first door 111 of the cabinet 110. When the power module 130 fails, the electrical connection member 135 remains electrically connected to ensure that the power module 130 can be powered on to check the fault state, and the waterway inlet and the waterway outlet are closed to disconnect the connection of the first heat exchange medium, thereby performing a fault check on the power module 130.

[0057] According to the centralized liquid cooling heat exchange unit 100 of the present application, it is used for a cabinet, the cabinet includes a server and a heat dissipation mechanism 201, the heat dissipation mechanism 201 is used to adjust the temperature of the server, the centralized liquid cooling heat exchange unit 100 includes a cabinet 110, a heat exchange module 120 and a power module 130, the heat exchange module 120 is configured as an integrated module, the heat exchange module 120 can be detachably installed in the cabinet 110, the heat exchange module 120 is used to adjust the temperature of the heat exchange medium of the cabinet heat dissipation mechanism 201, the power module 130 is configured as an integrated module, the power module 130 can be detachably installed in the cabinet 110, the power module 130 is used to drive the heat exchange medium flowing through the heat exchange module 120, wherein the power module 130 includes a connecting wall 132, the connecting wall 132 is provided with a waterway inlet 133, a waterway outlet 134 and an electrical connection component 135, the waterway outlet 134 is connected to the heat exchange module 120, and the electrical connection component 135 is used to be electrically connected to the cabinet. In this way, the heat exchange module 120 adopts an independent modular design, and the power module 130 adopts an independent modular design. The components that require maintenance in the heat exchange module 120 and the power module 130 are flexibly deployed and independently monitored, which reduces the system complexity and maintenance costs. When the water inlet 133 and the water outlet 134 of the power module 130 are both in the closed state, the electrical connection component 135 can remain energized to facilitate the maintenance of the driving component 131.

[0058] The power module 130 includes a driving member 131 (the driving member 131 is Figure 4 ), the driving component 131 is used to drive the heat exchange medium flowing through the heat exchange module 120. The driving module can drive the heat exchange medium to circulate in the system to ensure that the heat exchange and the medium can reach the equipment to be cooled. The driving module can drive the first heat exchange medium to circulate in the system to ensure that the first heat exchange medium can reach the equipment to be cooled. The heat exchange medium can be a coolant. The first heat exchange medium enters the heat exchange module 120 for heat exchange under the driving force of the driving component 131. The external cold source 200 can take away the heat of the first heat exchange medium.

[0059] The first heat exchange medium enters the driving member 131 through the waterway inlet 133. The waterway outlet 134 is connected to the heat exchange module 120. The first heat exchange medium from the driving member 131 is discharged through the waterway outlet 134. The first heat exchange medium from the driving member 131 enters the heat exchange module 120. The electrical connection member 135 is used to be electrically connected to the cabinet. Optionally, the electrical connection member 135 of the driving member 131 in the driving member 131 can be configured as a hand-insertion type fluid connector. As a result, it is possible to make it unnecessary to install a locking device on the cabinet 110.

[0060] In order to facilitate the connection of the centralized liquid cooling heat exchange unit to the cabinet, the connecting wall 132 of the driving member 131 faces the cabinet. This facilitates blind plugging. The water and electricity connector is set to a blind plug form, which means that water and electricity are connected when plugged in and disconnected when unplugged. The connecting wall 132 is provided with at least two connectors, and the interfaces of at least two connectors are located in the same plane. One connector has a waterway inlet 133, and the other connector has a waterway outlet 134. The two connectors are used to connect the waterway. Another connector has an electrical connection member 135. Another connector is used to connect the circuit. In this way, the waterway inlet 133, the waterway outlet 134 and the electrical connection member 135 are all arranged in the same plane. The waterway inlet 133, the waterway outlet 134 and the electrical connection member 135 are all arranged in the same connecting wall 132. The waterway inlet 133, the waterway outlet 134 and the electrical connection member 135 are all arranged on the same surface of the connecting wall 132. Optionally, one of the at least two connectors has a signal connection member for transmitting a control signal.

[0061] The connecting wall 132 is provided with a blind plug-in fluid connector, and the cabinet 110 is correspondingly provided with a fluid matching connector, and the fluid matching connector of the cabinet 110 matches the plane of the connecting wall 132. The fluid matching connector of the cabinet 110 includes a pipeline interface and an electrical matching component, and the pipeline interface and the electrical matching component can be connected to the connector independently. The pipeline interface includes a pipeline water outlet and a pipeline water inlet, and the pipeline water outlet can be independently connected to the waterway inlet 133 of the driving member, and the pipeline water inlet can be independently connected to the waterway outlet 134 of the driving member. The electrical matching component can be independently connected to the electrical connection component 135 of the driving member. When the pipeline water outlet is separated from the waterway inlet 133 of the driving member, the electrical matching component can remain connected to the electrical connection component 135. When the water inlet of the pipeline is separated from the waterway outlet 134 of the driving member, the electrical matching component can remain connected to the electrical connection component 135. When the water outlet of the pipeline is connected to the waterway inlet 133 of the driving component, the water inlet of the pipeline remains connected to the waterway outlet 134 of the driving component, and the electrical matching component remains connected to the electrical connection component 135.

[0062] The electrical connection member 135 of the connecting wall 132 is configured as a plug, and a socket matching the plug is correspondingly provided in the cabinet 110, and the socket of the cabinet 110 matches the plane of the connecting wall 132. The electrical connection member 135 of the connecting wall 132 is configured as a socket, and a plug matching the socket is correspondingly provided in the cabinet 110, and the plug of the cabinet 110 matches the plane of the connecting wall 132.

[0063] In order to ensure that the circuit is not disconnected, the power module 130 also includes a wire management component 180, and the wire management component 180 is connected to the electrical connection component 135. The wire management component 180 is configured as a wire management box. The wire management box can be installed at any position of the cabinet 110, and the driving component 131 is installed at a position convenient for maintenance and installation. The wire management component 180 includes a resilient component 182 and a wire component 181, and the wire component 181 is connected to the electrical connection component 135 through the resilient component 182. The wire component 181 is configured as an electric wire or a signal wire. Figure 5 As shown, the resilient member 182 includes an elastic disk and an elastic member, the elastic member is arranged in the elastic disk, and the wire member 181 is wrapped around the elastic disk. When an external force is applied to pull the wire member 181 outward, the wire member 181 is pulled out of the cable management disk. When no outward pulling force is applied to the wire member 181, the wire member 181 will be restored to its original position under the action of the elastic member and the elastic disk will be driven to retract into the cable management box. In this way, the longer wire member 181 is coiled in the cable management box and can be pulled out of the cable management box. After being pulled out, the pulled-out cables can be automatically retracted under the action of the cable management box.

[0064] One end of the wire component 181 in the wire management assembly 180 is connected to the male head of the electrical connection component 135 of the driving component 131. For example, one end of the wire component 181 in the wire management assembly 180 is connected to the inside (such as a power supply, a chip) of the electrical connection component 135 of the driving component 131. The female head is arranged on the cabinet 110. The water circuit and the circuit of the driving component 131 are in a connected state. The water circuit inlet 133 of the driving component 131 is connected to the pipeline outlet of the heat exchange medium of the cabinet 110. The electrical connection component 135 of the driving component 131 is electrically connected to the electrical matching component of the cabinet 110. An elastic disk is arranged in the wire management assembly 180, an elastic member is arranged in the elastic disk, and the wire component 181 is wound on the elastic disk. The elastic member is used to drive the wire component 181 to retract into the wire management box when there is no external force pulling the wire component 181.

[0065] When the driving component 131 needs to be repaired, the water inlet 133 of the driving component 131 and the pipeline outlet of the heat exchange medium of the cabinet 110 are separated from each other, and the electrical connection component 135 of the driving component 131 and the electrical matching component of the cabinet 110 remain connected under the action of the wiring assembly 180, ensuring the electrical and signal connectivity of the driving component 131 during the maintenance process to facilitate the maintenance of the circulating water pump.

[0066] Return now Figure 1In order to keep the heat exchange medium connected during maintenance, the power module 130 includes at least two driving components 131, and at least two driving components 131 are connected in parallel. The control component can control at least two driving components 131 to start separately. When one driving component fails, the control component controls another driving component to start, thereby ensuring that when one driving component 131 is repaired, the other driving component works to drive the heat exchange medium to keep flowing. Preferably, the power module 130 includes a first driving component 136 and a second driving component 137, and the first driving component 136 and the second driving component 137 are connected in parallel. When the first driving component 136 fails, the control component controls the second driving component 137 to start, thereby ensuring that when the first driving component 136 is repaired, the second driving component 137 works to drive the heat exchange medium to keep flowing. Of course, when the second driving component 137 fails, the control component can also control the first driving component 136 to start, thereby ensuring that when the second driving component 137 is repaired, the first driving component 136 works to drive the heat exchange medium to keep flowing.

[0067] At least two drive members 131 are arranged in parallel. At least two drive members 131 are modularly designed. Optionally, the drive member 131 is configured as a circulating water pump, and at least two circulating water pumps are arranged in parallel. At least two circulating water pumps are modularly designed. Figure 2 As shown, the position of the driving member 131 is set at the corresponding position of the first door 111 at the lower part of the cabinet 110. In this way, after the first door 111 is opened, the driving member 131 can be plugged in and installed. The driving member 131 can also be installed on the side of the cabinet 110, and a maintenance door is set on the side of the cabinet 110, and the maintenance door corresponds to the position of the driving member 131. In this way, the operator can install the water pump into the cabinet 110 by opening the maintenance door. For example, Figure 3 As shown, a second door 112 is installed on the side of the cabinet 110, and the second door 112 corresponds to the driving member 131. In this way, the operator can install the water pump into the cabinet 110 by opening the second door 112.

[0068] The centralized liquid-cooled heat exchange unit also includes a control module, which can monitor the opening and closing of each component of the centralized liquid-cooled heat exchange unit. The control module can control the opening and closing of the drive component 131 and the opening and closing of the valve. Sensors can be set on the water inlet and outlet pipes of each component in the centralized liquid-cooled heat exchange unit. The sensor can detect the temperature and pressure data of the heat exchange medium. The sensor can transmit the detected data to the control module, and the control screen of the control module can display the data parameters fed back by the sensor.

[0069] In order to ensure the cleanliness of the first heat exchange medium, Figure 1As shown, the centralized liquid cooling heat exchange unit 100 also includes a water quality module 150, which is connected to the heat exchange module 120.

The filter component 151 is configured as a filter. The filter component 151 is used to filter the first heat exchange medium. In particular, the filter component 151 is used to filter the first heat exchange medium discharged from the heat exchange module 120. Thereby, the cleanliness of the first heat exchange medium entering the heat dissipation mechanism 201 is ensured.

[0072] In an optional embodiment, the water quality module 150 also includes a water quality monitoring component, which is used to monitor the cleanliness of the first heat exchange medium. For example, the water quality monitoring component is used to monitor the water quality of the first heat exchange medium. The water quality monitoring component includes a control component and a monitoring component 152, and the monitoring component 152 is used to monitor the first heat exchange medium. The monitoring component 152 is used to monitor the cleanliness of the first heat exchange medium. The filter component 151 and the water quality monitoring component are integrated in the same module. For example, the filter component 151 and the water quality monitoring component are integrated in the same device.

[0073] The water quality module 150 includes a first monitoring component, which can be arranged downstream of the filter component 151. The first monitoring component is located between the filter component 151 and the heat dissipation mechanism 201. The first monitoring component can monitor the cleanliness of the first heat exchange medium from the filter component 151. The first monitoring component can monitor the cleanliness of the first heat exchange medium after filtering by the filter component 151. The water quality module 150 includes a second monitoring component, which can be arranged upstream of the filter component 151. The second monitoring component is located between the filter component 151 and the heat exchange module 120. The second monitoring component can monitor the cleanliness of the first heat exchange medium from the heat exchange module 120. The second monitoring component can monitor the cleanliness of the first heat exchange medium before filtering by the filter component 151.

[0074] The monitoring component 152 is connected to the control component in communication. The monitoring component 152 can feed back the monitoring data to the control component. The first monitoring component can feed back the cleanliness of the first heat exchange medium before filtration to the control component.

For example, the first switch component can control whether the first heat exchange medium enters the filter component 151. The first switch component can control whether the first heat exchange medium from the heat exchange module 120 enters the filter component 151.

[0076] The monitoring component 152 further includes a second pipeline and a second switch component, and the second pipeline connects the heat dissipation mechanism 201 and the filter component 151. The second switch component is arranged in the second pipeline. In particular, the second switch component is located between the second monitoring component and the filter component 151.

[0077] The monitoring component 152 further includes a third pipeline and a third switch component, and the third pipeline is connected in parallel with the filter component 151. The third switch component is set to the third pipeline. When the filter component 151 is maintained, the first switch component and the second switch component are both closed, and the third switch component is opened. The first heat exchange medium flows to the heat dissipation mechanism 201 through the third pipeline. The first heat exchange medium bypasses the heat dissipation mechanism 201 through the third pipeline.

[0078] The filter component 151 is installed on the pipeline. A bypass pipe is arranged around the filter component 151.

[0079] As an optional embodiment, the centralized liquid cooling heat exchange unit 100 further includes a pressure stabilizing module 160, which is detachably mounted in the cabinet 110. The pressure stabilizing module 160 is located upstream of the power module 130. The pressure stabilizing module 160 is configured as a pressure stabilizing tank or an expansion tank. The pressure stabilizing module 160 is used to adjust the pressure of the first heat exchange medium. The pressure stabilizing module 160 is connected to the power module 130.

[0080] The pressure stabilizing module 160 includes at least two pressure stabilizing tanks, and at least two pressure stabilizing tanks are connected in series. For example, the expansion tank of the pressure stabilizing tank may be in the shape of a capsule. A large pressure stabilizing tank may be disassembled into two small pressure stabilizing tanks, thereby reducing the volume occupied inside the cabinet 110 and avoiding affecting the number and / or volume of the driving components 131, so as to make greater use of the volume in the cabinet 110.

[0081] In order to ensure the amount of the first heat exchange medium in the centralized liquid cooling heat exchange unit 100, the centralized liquid cooling heat exchange unit 100 further includes a liquid replenishing module 170, which is detachably mounted in the cabinet 110. The liquid replenishing module 170 is in communication with the power module 130. The liquid replenishing module 170 is in communication with the waterway inlet 133 to replenish the heat exchange medium to the power module 130. In particular, the liquid replenishing module 170 can replenish the heat exchange medium to the driving component 131. The liquid replenishing module 170 replenishes the first heat exchange medium to the driving component 131.

[0082] Specifically, the rehydration module 170 is located upstream of the pressure stabilizing module 160. The rehydration module 170 can provide the first heat exchange medium to the pressure stabilizing module 160. The rehydration module 170 includes a rehydration pump 171 and a liquid storage device 172, and the rehydration pump 171 is used to drive the flow of the first heat exchange medium in the liquid storage device 172. The rehydration pump 171 can act as a circulation pump. The rehydration pump 171 can be detachably arranged in the cabinet 110. The rehydration pump 171 can also be equipped with a wiring management component. The liquid storage device 172 is used to store the first heat exchange medium to provide a stable source of the first heat exchange medium for the centralized liquid cooling heat exchange unit 100. Figure 3 As shown, a fourth door 114 is disposed on the side of the cabinet 110, and the position of the fourth door 114 corresponds to the position of the liquid replenishment module 170. When the liquid replenishment module 170 needs maintenance, the operator opens the fourth door 114 and can repair the liquid replenishment module 170.

[0083] Specifically, the liquid storage device 172 is used to store coolant to provide a stable source of coolant for the centralized liquid cooling heat exchange unit 100. When the first heat exchange medium is configured as water, the liquid storage device 172 is connected to the water source 173. The liquid storage device 172 is connected to the external water source 173. The water source 173 replenishes water to the liquid storage device 172. The liquid replenishment pump 171 drives the first heat exchange medium in the liquid storage device 172 to flow into the pressure stabilizing module 160.

[0084] As an optional embodiment, the cabinet 110 is further provided with a limiting device. The limiting device limits the position of the driving member 131. Preferably, the limiting device is provided at the first door 111 of the cabinet 110. When the driving member 131 is plugged in and out, the limiting device limits the position of the driving member 131, and the limiting device applies a plugging force to the driving member 131, so that the water and electricity device of the driving member 131 is in a connected state.

[0085] The limiting device can be constructed as a mechanical component. The limiting device includes a protrusion and a button, and the button matches the protrusion. The button can control the extension and retraction of the protrusion. When the power module 130 is installed, the power module 130 squeezes the protrusion back. After the power module 130 is installed in place, the protrusion pops out, thereby preventing the power module 130 from rebounding. At the same time, the button can be pressed to retract the protrusion so that the power module 130 can be removed.

[0086] Furthermore, the limiting device may further include a blocking member, which is used to prevent the power module 130 from rebounding. For example, the blocking member may be a blocking piece. The blocking piece may be installed on the cabinet 110 by threaded connection or other connection methods. After the power module 130 is installed in place, the blocking piece is installed in front of the power module 130 to prevent the power module 130 from rebounding.

[0087] The limit device has a locking position and a non-locking position. When the male and female ends of the driving member 131 are connected, the limit device is adjusted to the locking position. The limit device in the locking position limits the position of the driving member 131, so that the waterway and the circuit of the driving member 131 are in a connected state. The waterway inlet 133 of the driving member 131 is connected to the pipeline outlet of the heat exchange medium of the cabinet 110. The electrical connection member 135 of the driving member 131 is electrically connected to the electrical matching member of the cabinet 110.

[0088] When the driving component 131 needs to be repaired, the limit device is adjusted to the non-locking position. The water inlet 133 of the driving component 131 and the water outlet of the heat exchange medium pipeline of the cabinet 110 are separated from each other, the water circuit is disconnected, and the electrical connection component 135 of the driving component 131 and the electrical matching component of the cabinet 110 are kept in a connected state under the action of the wire management component 180, ensuring the connection of electricity and signals of the driving component 131 during the maintenance process, so as to facilitate the maintenance of the driving component 131.

[0089] In this way, the operator can open the first door 111 of the cabinet 110, install the power module 130 inside the cabinet 110, and then fix it through the locking device. When the first drive component 136 needs maintenance, the power module 130 switches to the second drive component 137 that does not require maintenance. After the locking device of the first drive component 136 that needs maintenance is opened, the first drive component 136 that needs maintenance is pulled out. Since the electrical connection component 135 of the first drive component 136 and the waterway inlet 133 and the waterway outlet 134 are all located on the same connecting wall 132, the circuit will not be disconnected, and the drive component 131 can be inspected. Similarly, when the second drive component 137 needs maintenance, the power module 130 switches to the first drive component 136 that does not require maintenance. After the locking device of the second drive component 137 that needs maintenance is opened, the second drive component 137 that needs maintenance is pulled out. Since the electrical connection member 135 of the second driving member 137 and the waterway inlet 133 and the waterway outlet 134 are all located on the same connecting wall 132 , the circuit will not be disconnected, and the driving member 131 can be repaired.

[0090] A third door 113 is provided on the side of the cabinet 110, and the position of the third door 113 corresponds to the position of the water quality module 150. When the water quality module 150 needs maintenance, the operator opens the third door 113 and can repair the water quality module 150. A maintenance door is provided on the side of the cabinet 110. The positions of the maintenance doors can correspond to the positions of the filter component 151 and the drive component 131, respectively. The area of ​​the maintenance door can only cover the drive component 131 or the filter component 151. When any component needs maintenance, the maintenance door can be opened to perform precise maintenance on the corresponding position. Of course, the position of the maintenance door can be flexibly changed according to the actual situation in the machine room.

[0091] like Figure 1 As shown, the pipeline system of the centralized liquid cooling heat exchange unit 100 is divided into a primary side pipeline part and a secondary side pipeline part. The primary side pipeline part connects the heat exchange module 120 with the external cold source 200, and the secondary side pipeline part connects the heat exchange module 120 with the indoor liquid cooling cabinet. The return water pipeline of the secondary side pipeline is connected in sequence with the voltage stabilizing module 160, the power module 130, the voltage stabilizing module 160 and the liquid replenishing module 170. When the centralized liquid cooling heat exchange unit 100 is running, the cooling water from the external cold source 200 enters the heat exchange module 120 for heat exchange and becomes high-temperature return water, and the high-temperature return water returns to the external cold source 200 for heat exchange and becomes cooling water again. The first heat exchange medium from the heat exchange module 120 passes through the water quality module 150, is filtered, parameter detected and analyzed, and then enters the liquid cooling cabinet to exchange heat with the heating element. The low-temperature first heat exchange medium becomes a high-temperature first heat exchange medium, and the high-temperature first heat exchange medium flows back to the centralized liquid cooling heat exchange unit 100 and re-enters the heat exchange module 120 under the action of the circulating water pump.

[0092] The power module 130 is installed in the pipeline and connected to the pipeline. The power module 130 integrates a driving component 131 (such as a water pump), a water pipe, a circuit, etc. The connecting wall 132 of the power module 130 is provided with a water supply port, a water return port and an electrical connection port. The connecting wall 132 of the power module 130 is also provided with a signal connection port. This enables the power module 130 to operate normally. The power module 130 also integrates a wire management component to extend the power module circuit. The power module 130 also integrates a sensor, and the sensor is directly integrated in the power module 130, and the control line is directly connected to the driving component 131 in the power module 130.

[0093] The driving member 131 is modularly installed in the centralized liquid cooling heat exchange unit 100. The waterway inlet 133 and the waterway outlet 134 of the driving member 131 are both arranged on the same connecting wall 132. In particular, the waterway inlet 133 and the waterway outlet 134 of the driving member 131 are both arranged on the same plane. The waterway inlet 133 and the waterway outlet 134 of the driving member 131 are arranged in a blind pluggable form. The waterway inlet 133, the waterway outlet 134 and the electrical connection member 135 are all arranged on the same connecting wall 132. In particular, the waterway inlet 133, the waterway outlet 134 and the electrical connection member 135 are all arranged on the same plane. The remaining relevant components of the driving member 131 are integrated in the module unit. The corresponding matching water and electricity connectors are retained in the centralized liquid cooling heat exchange unit 100 and the necessary installation space is reserved to realize the modularization of the driving member 131 and the convenient disassembly of the driving member 131. The modular setting of the drive module, combined with the design of the maintenance door, can simplify operation and maintenance. The centralized liquid-cooled heat exchange unit 100 can be opened for maintenance without shutting down, which avoids the drive component 131 being surrounded by pipelines and avoids the difficulty in maintaining the drive component 131 due to the difficulty in disassembling the pipelines. Each module of the centralized liquid-cooled heat exchange unit 100 is conveniently detachable, and each module can be plugged in and out by blind plugging or manual plugging. According to the centralized liquid-cooled heat exchange unit 100 of the present application, the components that need to be maintained, such as the power module 130, the water quality module 150 and the rehydration module 170, are flexibly deployed, and can be repaired online without shutting down the machine. Independent monitoring can simplify operation and maintenance, reduce system complexity and maintenance costs, and save time and effort. At the same time, the centralized liquid-cooled heat exchange unit 100 of the present application has both water purification and detection functions, which can warn the system water quality and remind the prediction of the cycle of water quality replacement or dosing.

[0094] The centralized liquid cooling heat exchange unit 100 of the present application can be compatible with the installation of various categories and models of IT equipment, reduce the restrictions between cabinets and servers, and deliver cabinets and servers in a decoupled manner. Aiming at the pain points of cold plate liquid cooling air and liquid cooling separation, the pipe connection and control method architecture is first created to achieve cold plate liquid cooling cabinet-level air-liquid fusion. The removable blind plug bus can flexibly adjust the position of the liquid cooling cabinet bus through modular design. The water and electricity blind plug design enables rapid node-level installation and maintenance, improving efficiency by more than 30%. Through customized interfaces and optimized flow resistance, PUE is as low as below 1.15. High-reliability technology is adopted, with water and electricity separation, leakage detection, drip-free connectors, and long-life hoses. The centralized liquid cooling heat exchange unit 100 of the present application has functions such as asset management, power consumption management, liquid cooling leakage detection, power module management, battery module management, etc., supports on-demand cooling, automatically adjusts the cold water flow in the node, and reduces PUE.
