Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to a computing device and a connector module. Background Technology

[0002] The computing device includes a cabinet and computing nodes. The computing nodes are located inside the cabinet and can be connected to the cabinet via fasteners. Each computing node has a liquid cooling unit with a first connector, and the cabinet has a second connector. When the computing node is installed in the cabinet, the first connector and the second connector are plugged in, allowing coolant to flow into the liquid cooling unit to dissipate heat from the computing node.

[0003] In related technologies, the flexibility and timeliness of cutting off the coolant flow loop of computing devices are relatively poor. Summary of the Invention

[0004] This application provides a computing device and a connector module, which offer high flexibility and timeliness when the first connector and the second connector in the computing device are disconnected.

[0005] In a first aspect, embodiments of this application provide a computing device, including: a cabinet, a node, a first connector, and a second connector, wherein the node is disposed within the cabinet; the first connector includes a first body, a first piston assembly, and a first stop member, the first body being sleeved on the outside of the first piston assembly; the second connector includes a second body; the second body is mated with the first body; one of the first body and the second body is connected to the cabinet, and the other is connected to the node; wherein, when the first stop member is in a first position, the first stop member axially limits the first piston assembly relative to the first body, the first piston assembly is inserted into the second body, and the first connector is connected to the second connector; when the first stop member is in a second position, the first piston assembly is axially movable relative to the first body, and the first connector is disconnected from the second connector.

[0006] The computing device provided in this application embodiment includes a first body, a first piston assembly, and a first stop member in a first connector, and a second body in a second connector. When the first stop member limits the axial movement of the first piston assembly relative to the first body, the first piston assembly is inserted into the second body to connect the first connector and the second connector. At this time, coolant can be supplied to the node through the connected first and second connectors. When it is necessary to disconnect the coolant circuit of the node, the first stop member is disengaged from either the first piston assembly or the first body. The first stop member no longer limits the first piston assembly and the first body, and the first piston assembly can move relative to the first body to exit from the second connector, thereby disconnecting the first connector from the second connector. After the node is installed on the cabinet, the first body and the second body can remain in a mated state. Moving the first stop member from the first position to the second position disconnects the first connector from the second connector. Therefore, there is no need to remove the node from the cabinet, the operation is simple, and the flexibility and timeliness of disconnecting the first and second connectors in the connector module are high.

[0007] In one possible implementation, the computing device provided in this application embodiment has a first mounting groove on a first piston assembly and a second mounting groove on a first body, with a first stop member inserted into the first and second mounting grooves. The first stop member limits the first piston assembly and the first body, and the method of the first stop member no longer limiting the first piston assembly and the first body is relatively simple.

[0008] In one possible implementation, the computing device provided in this application embodiment has a first mounting groove, which is a first recess formed on a first piston assembly, with the opening of the first recess facing the first body; and a second mounting groove, which is a through groove extending radially through the first body. The first recess and the through groove are arranged radially opposite to each other. When the first stop member is inserted into the first recess, the bottom wall of the first recess can limit the first stop member, thus preventing the first stop member from falling into the first connector. It also avoids the need for additional limiting structures to prevent the first stop member from falling out.

[0009] In one possible implementation, the computing device provided in this application embodiment has a first mounting slot and a second mounting slot that are both through slots. The first mounting slot and the second mounting slot are arranged radially opposite to each other. The first stop member includes a stop member body and a limiting part. The stop member body is inserted into the first mounting slot and the second mounting slot, and the limiting part abuts against the side of the first body away from the first piston assembly. The fact that both the first mounting slot and the second mounting slot are through slots facilitates the insertion of the first stop member into the first mounting slot and the second mounting slot.

[0010] In one possible implementation, the computing device provided in this application embodiment includes a ball bearing as the first stop member, and a trigger member as the first connector. The trigger member is sleeved on the outside of the first body. The trigger member has an abutment portion and a second groove on the side facing the first body, with the second groove and the abutment portion arranged axially. When the ball bearing is in the first position, the abutment portion abuts against the ball bearing radially, limiting the ball bearing within the through groove and the first groove. When the ball bearing is in the second position, the second groove and the ball bearing are radially aligned, with the ball bearing partially located within the second groove. By setting the first stop member as a ball bearing, the ball bearing and the abutment portion are in point contact. Therefore, the force required to move the trigger member is relatively small. The inner wall of the first groove is an arc surface matching the outer surface of the ball bearing. When the trigger member moves, the ball bearing rotates, and the resistance to be overcome when applying force to the trigger member is small, further reducing the force applied to the trigger member. Therefore, the ball bearing can easily switch between two positions, thereby conveniently controlling the connection and disconnection of the first connector and the second connector.

[0011] In one possible implementation, the computing device provided in this application embodiment has multiple through slots, which are evenly spaced circumferentially on the first body. The first groove, through slots, and ball bearings are arranged in a one-to-one correspondence. This results in a more reliable connection between the first body and the piston assembly, and a more uniform force distribution on the piston assembly along the circumferential direction.

[0012] In one possible implementation, the computing device provided in this application includes a first body having a first and a second axially opposed limiting surface, and a trigger having a third and a fourth axially opposed limiting surface, located axially between the first and second limiting surfaces, with the third limiting surface closer to the first limiting surface and the fourth limiting surface closer to the second limiting surface. The first connector further includes a first elastic member, which abuts axially between the second and fourth limiting surfaces. The first limiting surface abuts against the third limiting surface. This abutment between the first and third limiting surfaces prevents the trigger from moving axially to the second connector, thus preventing it from losing its limiting and triggering function on the ball. The elastic force of the first elastic member is continuously applied to the trigger, thereby preventing the second groove from aligning with the ball when the trigger moves towards the second limiting surface without disconnecting the connection between the first and second connectors.

[0013] In one possible implementation, the computing device provided in this application includes a first piston assembly comprising a first valve housing and a first valve core, the first valve core being located within the first valve housing and axially movable relative to the first valve housing; the second connector further includes a push rod and a second valve core, the second valve core being radially located between the push rod and the second body, and the second valve core being axially movable relative to the second body; when the first stop member is in a first position and the first piston assembly is inserted into the second body, the push rod pushes the first valve core to move relative to the first valve housing, and the first valve housing pushes the second valve core to move relative to the second body, thus connecting the first connector and the second connector. The first stop member limits the first valve housing and the first body, keeping them stationary. When the first connector and the second connector are plugged in, the first valve core and the second valve core move relative to the first valve housing and the second valve housing respectively, allowing both the first connector and the second connector to communicate normally.

[0014] In one possible implementation, the computing device provided in this application includes a first piston assembly further comprising a second elastic element abutting between a first valve housing and a first valve core; a second connector including a third elastic element abutting between a second body and a second valve core; when the first stop member is in the second position, under the elastic force of the second and third elastic elements, the first piston assembly is axially movable relative to the first body in a direction away from the second connector, and the first connector is disconnected from the second connector. By providing the second and third elastic elements, after the first stop member no longer limits the first valve housing and the first body, the elastic force of the second and third elastic elements allows the first piston assembly to move away from the second connector and exit from the second connector, thereby eliminating the need for manual or external force to move the first piston assembly.

[0015] In one possible implementation, the computing device provided in this application embodiment has a first body having a fifth limiting surface and a first piston assembly having a sixth limiting surface; the first connector further includes a fourth elastic member, which abuts between the fifth limiting surface and the sixth limiting surface.

[0016] In one possible implementation, the sum of the elastic forces of the second and third elastic elements is greater than the elastic force of the fourth elastic element. Therefore, when it is necessary to disconnect the first connector from the second connector, the elastic forces of the second and third elastic elements can overcome the elastic force of the fourth elastic element by adjusting the position of the first stop element, causing the first piston assembly to move towards the fourth elastic element.

[0017] In one possible implementation, the computing device provided in this application further includes a controller. A leakage detector is disposed in the node and electrically connected to the controller. The first connector further includes a trigger element, which triggers a first stop element to switch between a first position and a second position. When the leakage detector detects leakage in the node, the controller controls the trigger element to switch the first stop element to the second position. Therefore, when the leakage detector detects leakage, the controller can respond promptly and control the trigger element to operate, further improving the timeliness when the first and second connectors disconnect.

[0018] Secondly, embodiments of this application provide a connector module, including a first connector and a second connector. The first connector includes a first body, a first piston assembly, and a first stop member. The first body is sleeved on the outside of the first piston assembly. The second connector includes a second body. The second body is mated with the first body. When the first stop member is in a first position, the first stop member limits the first piston assembly relative to the first body in the axial direction. The first piston assembly is inserted into the second body, and the first connector is connected to the second connector. When the first stop member is in a second position, the first piston assembly is axially movable relative to the first body, and the first connector is disconnected from the second connector.

[0019] In one possible implementation, the connector module provided in this application has a first mounting groove on a first piston assembly and a second mounting groove on a first body, with a first stop member inserted into the first and second mounting grooves. The first stop member limits the first piston assembly and the first body, and the method of the first stop member no longer limiting the first piston assembly and the first body is relatively simple.

[0020] In one possible implementation, the connector module provided in this application has a first mounting groove, which is a first recess formed on the first piston assembly, with the opening of the first recess facing the first body; and a second mounting groove, which is a through groove extending radially through the first body. The first recess and the through groove are radially opposite to each other. When the first stop member is inserted into the first recess, the bottom wall of the first recess can limit the first stop member, thus preventing the first stop member from falling into the first connector. This also avoids the need for additional limiting structures to prevent the first stop member from falling out.

[0021] In one possible implementation, the connector module provided in this application embodiment has a first mounting slot and a second mounting slot that are both through slots. The first mounting slot and the second mounting slot are arranged radially opposite to each other. The first stop member includes a stop member body and a limiting part. The stop member body is inserted into the first mounting slot and the second mounting slot, and the limiting part abuts against the side of the first body away from the first piston assembly. The fact that both the first mounting slot and the second mounting slot are through slots facilitates the insertion of the first stop member into the first mounting slot and the second mounting slot.

[0022] In one possible implementation, the connector module provided in this application includes a ball as the first stop member and a trigger member as the first connector. The trigger member is sleeved on the outside of the first body. The trigger member has an abutment portion and a second groove on the side facing the first body, and the second groove and the abutment portion are arranged axially. When the ball is in the first position, the abutment portion abuts against the ball radially, limiting the ball in the through groove and the first groove. When the ball is in the second position, the second groove and the ball are aligned radially, and the ball portion is located in the second groove, so that the first piston assembly can move axially relative to the first body. By setting the first stop member as a ball, the ball and the abutment portion are in point contact. Therefore, the force required to move the trigger member is small. The inner wall of the first groove is an arc surface that matches the outer surface of the ball. When the trigger member moves, the ball rotates, and the resistance to be overcome when applying force to the trigger member is small, further reducing the force applied to the trigger member. Therefore, the ball can easily switch between two positions, thereby conveniently controlling the connection and disconnection of the first connector and the second connector.

[0023] In one possible implementation, the connector module provided in this application has multiple through slots, which are evenly spaced circumferentially on the first body. The first groove, through slots, and ball bearings are arranged in a one-to-one correspondence. This results in a more reliable connection between the first body and the piston assembly, and a more uniform force distribution on the piston assembly along the circumferential direction.

[0024] In one possible implementation, the connector module provided in this application includes a first body with a first and a second axially opposed limiting surface, and a trigger with a third and a fourth axially opposed limiting surface, located axially between the first and second limiting surfaces, with the third limiting surface closer to the first limiting surface and the fourth limiting surface closer to the second limiting surface. The first connector further includes a first elastic member, which abuts axially between the second and fourth limiting surfaces. The first limiting surface abuts against the third limiting surface. This abutment between the first and third limiting surfaces prevents the trigger from moving axially to the second connector, thereby losing its limiting and triggering function on the ball. The elastic force of the first elastic member is continuously applied to the trigger, thus preventing the trigger from moving towards the second limiting surface and aligning the second groove with the ball without disconnecting the connection between the first and second connectors.

[0025] In one possible implementation, the connector module provided in this application includes a first piston assembly comprising a first valve housing and a first valve core, the first valve core being located within the first valve housing and axially movable relative to the first valve housing; the second connector further includes a push rod and a second valve core, the second valve core being radially located between the push rod and the second body, and axially movable relative to the second body; when the first stop member is in a first position and the first piston assembly is inserted into the second body, the push rod pushes the first valve core to move relative to the first valve housing, and the first valve housing pushes the second valve core to move relative to the second body, thus connecting the first connector and the second connector. The first stop member limits the first valve housing and the first body, keeping them stationary. When the first connector and the second connector are inserted, the first valve core and the second valve core move relative to the first valve housing and the second valve housing respectively, allowing both the first connector and the second connector to communicate normally.

[0026] In one possible implementation, the connector module provided in this application includes a first piston assembly further comprising a second elastic element abutting between a first valve housing and a first valve core; the second connector includes a third elastic element abutting between a second body and a second valve core; when the first stop member is in the second position, under the elastic force of the second and third elastic elements, the first piston assembly is axially movable relative to the first body in a direction away from the second connector, and the first connector is disconnected from the second connector. By providing the second and third elastic elements, after the first stop member no longer limits the first valve housing and the first body, the elastic force of the second and third elastic elements allows the first piston assembly to move away from the second connector and exit from the second connector, thereby eliminating the need for manual or external force to move the first piston assembly.

[0027] In one possible implementation, the connector module provided in this application embodiment has a first body having a fifth limiting surface and a first piston assembly having a sixth limiting surface; the first connector further includes a fourth elastic member, which abuts between the fifth limiting surface and the sixth limiting surface.

[0028] In one possible implementation, the sum of the elastic forces of the second and third elastic elements is greater than the elastic force of the fourth elastic element. Therefore, when it is necessary to disconnect the first connector from the second connector, the elastic forces of the second and third elastic elements can overcome the elastic force of the fourth elastic element by adjusting the position of the first stop element, causing the first piston assembly to move towards the fourth elastic element.

[0076] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0077] This application provides a computing device and a connector module, which offer high flexibility and timeliness when the first and second connectors in the computing device are disconnected.

[0078] Figure 1 This is a schematic diagram of the structure of a data center provided in an embodiment of this application.

[0079] See Figure 1 As shown, the data center 1000 is used to transmit, accelerate, display, compute, and store data information. The data center 1000 provided in this embodiment may include a computing device 10, which is located within the computer room 20. The computing device 10 can be a server, such as a high-density server, tower server, rack server, or full-rack server. Among these, full-rack servers are widely used in cloud computing, big data, and artificial intelligence fields due to their advantages such as high space utilization and high power efficiency.

[0080] The structure of computing device 10 will now be described using a rack-mount server as an example.

[0081] Figure 2 This is a schematic diagram of the structure of a computing device provided in an embodiment of this application; Figure 3 Another schematic diagram of the computing device provided in an embodiment of this application.

[0082] See Figure 2 and Figure 3 As shown, the computing device 10 includes a cabinet 100 and multiple nodes 200, all of which are located in the cabinet 100.

[0083] The cabinet 100 has a cuboid structure and includes a first direction X, a second direction Y, and a third direction Z. The cabinet 100 supports and accommodates multiple nodes 200, which are spaced apart along the third direction Z. The nodes 200 can be computing nodes, switching nodes, or power supply nodes. Specifically, the cabinet 100 includes a front side 110 and a rear side 120. The front side 110 has a door panel 111 on one side. The cabinet 100 has multiple slide rails 130 extending along the second direction Y. The nodes 200 are placed on the slide rails 130 and inserted into the cabinet 100 from the front side 110 along the second direction Y. The cabinet 100 also includes support columns 140, to which the nodes 200 can connect.

[0084] As the computing power of computing device 10 increases, the heat dissipation of node 200 during operation increases. Liquid cooling has the advantage of high cooling efficiency, and node 200 can be cooled by liquid cooling.

[0085] The following uses a computing node as an example to illustrate the structure of node 200 and the connection method between node 200 and cabinet 100.

[0086] Figure 4 This is a schematic diagram of the structure of the cooling capacity distribution device and node in the computing device provided in the embodiments of this application; Figure 5 This is a schematic diagram of the structure of a node in a computing device provided in an embodiment of this application.

[0087] See Figure 4 and Figure 5 As shown, node 200 includes a housing 210, which is mounted on the slide rail 130 of cabinet 100 and connected to the support column 140. A circuit board 220 is housed within the housing 210 and connected to it. The circuit board 220 houses a processor 221, memory 222, or other components. A cooling module 230 can be used to dissipate heat from these components. The cooling module 230 includes a cold plate 231, a cold plate inlet pipe 232, and a cold plate return pipe 233. The cold plate 231 can be mounted on these components. Figure 4 and Figure 5 In the processor 221, a cold plate 231 is mounted. Figure 4 The image shows two cold plates 231, with a connecting pipe 234 between the two cold plates 231.

[0088] Please continue reading Figures 2 to 5 As shown, the cooling distribution device 300 is used to supply coolant to the computing device 10. The cooling distribution device 300 can be installed inside the cabinet 100 of the computing device 10 or in the data center 1000. Figure 2 In the illustrated embodiment, the cooling capacity distribution device 300 is installed inside the cabinet 100. The cooling capacity distribution device 300 includes a heat exchanger 310, an inlet pipe 320, and a return pipe 330. The heat exchanger 310 can be located inside the cabinet 100 or outside the cabinet 100. Figure 2 and Figure 4 In this configuration, heat exchanger 310 is located at the bottom of cabinet 100 along the third direction Z. Both inlet pipe 320 and return pipe 330 are connected to heat exchanger 310. Inlet pipe 320 and return pipe 330 are positioned near the rear side 120 of cabinet 100 and extend along the third direction Z within cabinet 100. Inlet pipe 320 is connected to cold plate inlet pipe 232 located at node 200, and return pipe 330 is connected to cold plate return pipe 233 located at node 200.

[0089] The heat exchanger 310, the liquid inlet pipe 320, the cooling module 230 in a node 200, and the liquid return pipe 330 form a coolant loop corresponding to this node 200.

[0090] For example, the coolant in the heat exchanger 310 is split from the inlet pipe 320 and flows into the cold plate inlet pipes 232 of multiple nodes 200. After flowing through two cold plates 231 in node 200, it flows out from the cold plate return pipe 233, converges into the return pipe 330, and returns to the heat exchanger 310 from the return pipe 330 for cooling. This cycle is repeated to dissipate heat from node 200.

[0091] Figure 6 This is a schematic diagram of the connector module provided in an embodiment of this application.

[0092] See Figure 3 , Figure 4 and Figure 6 As shown, the computing device 10 also includes a connector module 400, through which the cold plate liquid inlet pipe 232 and the liquid inlet pipe 320 are connected, and the cold plate liquid return pipe 233 and the liquid return pipe 330 can be connected through the connector module 400.

[0093] The connector module 400 connecting the cold plate inlet pipe 232 and the inlet pipe 320 will be described below. The connector module 400 includes a first connector 410 and a second connector 420. One of the first connector 410 and the second connector 420 communicates with the cold plate inlet pipe 232 in node 200, and the other communicates with the inlet pipe 320. For example, the first connector 410 communicates with the cold plate inlet pipe 232 in node 200, and the second connector 420 communicates with the inlet pipe 320. The cold plate inlet pipe 232 may be a flexible hose; therefore, the first connector 410 can also be fixed to the housing 210. The inlet pipe 320 is rigid; therefore, the second connector 420 can be fixed to the inlet pipe 320.

[0094] When node 200 is inserted into cabinet 100 from the front side 110 along slide rail 130 in the second direction Y, the first connector 410 and the second connector 420 are simultaneously connected, thus connecting the coolant circuit in computing device 10. Coolant is conductive; if the cooling module 230 in some nodes 200 leaks, the coolant will conduct electricity through the components in node 200, causing short circuits and affecting the normal operation of node 200. Leaking coolant may also flow into other nodes 200, affecting their operation. The greater the coolant leakage, the greater the impact on the normal operation of computing device 10; therefore, it is necessary to switch the coolant circuit in the leaking node 200 promptly.

[0095] The connector module 400 provided in this application embodiment includes a first connector 410 and a second connector 420. By improving the internal structure of the connector module 400, the first connector 410 and the second connector 420 can be disconnected without removing the node 200 from the cabinet 100, thus providing greater flexibility and timeliness in cutting off the coolant circuit corresponding to the leaking node 200. It should be noted that the connector module 400 provided in this application embodiment can also be used in other liquid-cooled devices.

[0098] See Figures 7 to 10 As shown, the first connector 410 includes a first body 411, a first piston assembly 412, and a first stop member 413. The first body 411 is sleeved on the outside of the first piston assembly 412. The second connector 420 includes a second body 421, which is mated with the first body 411. When the first stop member 413 is in the first position, it axially limits the first piston assembly 412 relative to the first body 411, keeping the first piston assembly 412 stationary relative to the first body 411 along the axial direction L. The first piston assembly 412 is inserted into the second body 421 to enable communication between the first connector 410 and the second connector 420. When the first stop member 413 is in the second position, the first piston assembly 412 can move relative to the first body 411 along the axial direction L, thereby disconnecting the communication between the first connector 410 and the second connector 420.

[0099] The connector module 400 may have a cylindrical outer periphery and includes an axial direction L, a circumferential direction C, and a radial direction R. The axial direction L of the connector module 400 is the direction in which the first connector 410 and the second connector 420 are inserted. In this embodiment, the axial direction L is consistent with the second direction Y of the cabinet 100.

[0100] In one possible implementation, the first connector 410 can be a female connector, the second connector 420 can be a male connector, and the first piston assembly 412 and the first stop member 413 are both disposed on the female connector. In another possible implementation, the first connector 410 can be a male connector, the second connector 420 can be a female connector, and the first piston assembly 412 and the first stop member 413 are both disposed on the male connector. Figures 7 to 10 In subsequent embodiments, the example is that both the first piston assembly 412 and the first stop member 413 are disposed on the female connector.

[0101] Figure 11 This is a schematic diagram of the structure of the first connector in the connector module provided in the embodiments of this application; Figure 12 for Figure 11 A schematic diagram of one state of the first connector is shown; Figure 13 for Figure 11 A schematic diagram of another state of the first connector shown; Figure 14 for Figure 13 An explosion diagram.

[0102] See Figures 11 to 14As shown, the first connector 410 includes a first body 411, with one end of the first body 411 facing away from the second connector 420 and towards node 200, and connected to the cold plate inlet pipe 232. The first connector 410 also includes a first piston assembly 412, which is inserted into the first body 411 and faces the second connector 420. The first body 411 can be connected to the housing 210 of node 200.

[0103] The first connector 410 also includes a first stop member 413, which can be a fastener. Please refer to [link to previous section]. Figure 12 As shown, when the first stop member 413 is inserted into the first piston assembly 412 and the first body 411, the first stop member 413 can restrict the movement of the first piston assembly 412 relative to the first body 411, so that the first piston assembly 412 remains stationary relative to the first body 411. The first piston assembly 412 extends axially L from one end of the first body 411 toward the second connector 420. The first stop member 413 is inserted into the first piston assembly 412 and the first body 411 at a position that limits the movement of the first piston assembly 412 relative to the first body 411, which is defined as the first position. Please continue to see... Figure 13 As shown, when the first stop member 413 is pulled out from either the first piston assembly 412 or the first body 411, the first stop member 413 no longer limits the first piston assembly 413, and the first piston assembly 412 can move axially relative to the first body 411. The position where the first stop member 413 no longer limits the first piston assembly 413 is the second position.

[0104] Please continue with the plugin. Figures 7 to 10 As shown, the second connector 420 includes a second body 421, one end of which, opposite to the first connector 410, is connected to the inlet pipe 320. When the node 200 is inserted into the cabinet 100, the second connector 420 is aligned with the first connector 410 along the axial direction L. The second body 421 can be connected to either the inlet pipe 320 or the return pipe 330.

[0105] Please continue reading Figure 9 As shown, when node 200 is inserted into cabinet 100, first stop member 413 keeps first piston assembly 412 relative to first body 411. First piston assembly 412 is stationary relative to first body 411 along axis L. First piston assembly 412 extends from one end of first body 411 toward second connector 420 to be inserted into second body 421 so that first connector 410 communicates with second connector 420. Coolant can enter the cooling module 230 of node 200 from through second connector 420 and first connector 410.

[0106] Please continue reading Figure 10 As shown, when it is necessary to cut off the coolant circuit between the cooling capacity distribution device 300 and the node 200, the first stop member 413 is pulled out from either the first piston assembly 412 or the first body 411. The first piston assembly 412 moves away from the second body 421 to exit from the second connector 420. After the first piston assembly 412 exits from the second connector 420, the first connector 410 and the second connector 420 are disconnected, thereby cutting off the coolant circuit between the cooling capacity distribution device 300 and the node 200.

[0107] The computing device 10 provided in this application embodiment comprises a first body 411, a first piston assembly 412, and a first stop member 413 disposed in a first connector 410; and a second body 421 disposed in a second connector 420. When the first stop member 413 limits the movement of the first piston assembly 412 relative to the first body 411, the first piston assembly 412 is inserted into the second body 421 to connect the first connector 410 and the second connector 420. When it is necessary to disconnect the coolant circuit between the cooling distribution device 300 and the node 200, it is only necessary to pull out the first stop member 413 from either the first piston assembly 412 or the first body 411. The first piston assembly 412 can then move relative to the first body 411 to exit the second connector 420, thereby disconnecting the first connector 410 from the second connector 420. After node 200 is installed on cabinet 100, the first body 411 and the second body 421 remain in a docked state. Simply moving the first stop 413 from the first position to the second position will disconnect the first connector 410 from the second connector 420. Compared with related technologies that require removing the node from the cabinet to disconnect the first connector and the second connector, the steps of moving the first stop 413 are fewer, and the flexibility and timeliness of disconnecting the first connector and the second connector in the connector module 400 are higher.

[0108] The specific manner in which the first stop member 413 limits the first piston assembly 412 and the first body 411 will be described below.

[0109] Please continue reading Figures 11 to 14 As shown, the first piston assembly 412 has a first mounting groove 4121, the first body 411 has a second mounting groove 4111, and the first stop member 413 is inserted into the first mounting groove 4121 and the second mounting groove 4111 to keep the first piston assembly 412 stationary relative to the first body 411.

[0110] The first stop member 413 can be a pin. When limiting the first piston assembly 412 and the first body 411, the first piston assembly 412 is moved along the axial direction L so that the first mounting groove 4121 and the second mounting groove 4111 are aligned along the axial direction L. The first stop member 413 is then inserted into the first mounting groove 4121 and the second mounting groove 4111 to limit the first piston assembly 412 and the first body 411. When the first stop member 413 no longer needs to limit the first piston assembly 412 and the first body 411, it can be pulled out from at least one of the first mounting groove 4121 and the second mounting groove 4111. The methods of the first stop member 413 limiting the first piston assembly 412 and the first body 411 and the methods of the first stop member 413 no longer limiting the first piston assembly 412 and the first body 411 are relatively simple.

[0111] In one possible implementation, both the first mounting groove 4121 and the second mounting groove 4111 are through grooves. The first stop member 413 includes a stop member body and a limiting portion. The stop member body is inserted into the first mounting groove 4121 and the second mounting groove 4111, and the limiting portion abuts against the side of the first body opposite to the first piston assembly 412. The fact that both the first mounting groove 4121 and the second mounting groove 4111 are through grooves facilitates the insertion of the first stop member 413 into them. The limiting portion prevents the first stop member 413 from falling into the first connector 410.

[0112] In another possible implementation, the first mounting groove 4121 is a first recess 4121a recessed in the first piston assembly 412 along the radial direction R away from the first body 411, and the opening of the first recess 4121a faces the first body 411; the second mounting groove 4111 is a through groove 4111a that passes through the first body 411 along the radial direction R.

[0113] The first body 411 is sleeved on the outside of the first piston assembly 412. The first stop member 413 needs to pass through the first body 411 when inserted and removed. Therefore, the second mounting groove 4111 is a through groove 4111a that penetrates the first body 411 radially R, thus facilitating the insertion and removal of the first stop member 413 via the second mounting groove 4111. The first groove 4121a is a non-through groove. When the first stop member 413 is inserted into the first groove 4121a, the bottom wall of the first groove 4121a can limit the first stop member 413, preventing it from falling into the first connector 410. This also avoids the need for additional limiting structures to prevent the first stop member 413 from falling out.

[0114] The first stop element 413 can also be a ball. The following explanation will take the example of the first stop element 413 being a spherical ball 413a. Figure 15This is another structural schematic diagram of the first connector in the connector module provided in the embodiments of this application; Figure 16 for Figure 15 An explosion diagram; Figure 17 for Figure 15 A schematic diagram of one state of the first connector is shown; Figure 18 for Figure 15 A schematic diagram of another state of the first connector shown; Figure 19 for Figure 18 An explosion diagram.

[0115] See Figures 15 to 18 As shown, in one possible implementation, the first stop member 413 is a spherical ball 413a, and the first connector 410 further includes a trigger member 414, which is sleeved on the outside of the first body 411. The trigger member 414 has an abutment portion 4141 and a second groove 4142 on the side facing the first body 411. The second groove 4142 and the abutment portion 4141 are arranged along the axial direction L, and the second groove 4142 is recessed into the trigger member 414 away from the first body 411. When the spherical ball 413a is in the first position, the abutment portion 4141 abuts the ball 413a in the radial direction R. The spherical ball 413a abuts against the first body 411 and the first piston assembly 412, thereby limiting the spherical ball 413a in the through groove 4111a and the first groove 4121a. When the spherical ball 413a is in the second position, the trigger 414 moves along the axial direction L, the second groove 4142 is radially aligned with the spherical ball 413a, the spherical ball 413a disengages from the first groove 4121a and is partially located in the second groove 4142, so that the first piston assembly 412 can move relative to the first body 411 along the axial direction L.

[0116] The abutting portion 4141 of the trigger member 414 abuts against the side of the spherical ball 413a away from the first piston assembly 412 along the radial direction R. Thus, the spherical ball 413a can be partially inserted into the through groove 4111a and partially inserted into the first groove 4121a to limit the first body 411 and the first piston assembly 412.

[0117] The trigger 414 also has a second groove 4142. When it is necessary to remove the ball bearing 413a from the first body 411 and the first piston assembly 412, a force is applied to the trigger 414, causing the trigger 414 to move along the axial direction L, so that the second groove 4142 aligns with the ball bearing 413a. The thrust of the push rod 422 causes the first piston assembly 412 to tend to move along the axial direction L, and the ball bearing 413a moves away from the first piston assembly 412 along the radial direction R to disengage from the first groove 4121a, so that the first piston assembly 412 and the first body 411 are no longer limited by the first stop member 413. The push of the push rod 422 causes the first piston assembly 412 to move along the axial direction L.

[0118] By setting the first stop 413 as a spherical ball 413a, the spherical ball 413a makes point contact with the abutment 4141. Therefore, the force exerted when the trigger 414 is moved is small. The inner wall of the first groove 4121a is an arc surface that matches the outer surface of the spherical ball 413a. When the trigger 414 moves, the spherical ball 413a rotates. The resistance that needs to be overcome when applying force to the trigger 414 is small, which further reduces the force applied to the trigger 414.

[0119] When the spherical ball 413a is no longer confining the first body 411 and the first piston assembly 412, it is accommodated in the second groove 4142, which prevents the spherical ball 413a from falling out of the connector module 400. In one possible implementation, please refer to... Figures 17 to 19 As shown, there are multiple through grooves 4111a, which are evenly spaced along the circumferential direction C on the first body 411. The first groove 4121a, the through grooves 4111a and the spherical ball 413a are arranged in a one-to-one correspondence.

[0120] The trigger 414 is sleeved on the outside of the first body 411, and the abutment portion 4141 simultaneously abuts against multiple spherical balls 413a. This allows the spherical balls 413a to limit the connection between the first body 411 and the piston assembly 412, making the connection between the first body 411 and the piston assembly 412 more reliable and ensuring more uniform force distribution on the piston assembly 412 along the circumferential direction C. Furthermore, when the trigger 414 moves along the axial direction L, the multiple spherical balls 413a can simultaneously disengage from multiple first grooves 4121a. The use of multiple spherical balls 413a improves the reliability of the connection between the first body 411 and the piston assembly 412 without increasing the steps required for disconnection, thus providing greater flexibility and timeliness when disconnecting the first connector 410 and the second connector 420.

[0121] Please continue reading Figures 17 to 19As shown, the first body 411 has a first limiting surface 4112 and a second limiting surface 4113 opposite each other along the axial direction L. The trigger member 414 has a third limiting surface 4143 and a fourth limiting surface 4144 opposite each other along the axial direction L. The third limiting surface 4143 and the fourth limiting surface 4144 are located between the first limiting surface 4112 and the second limiting surface 4113 along the axial direction L, and the third limiting surface 4143 is close to the first limiting surface 4112, and the fourth limiting surface 4144 is close to the second limiting surface 4113. The first connector 410 also includes a first elastic member 415, which abuts against the second limiting surface 4113 and the fourth limiting surface 4144 along the axial direction. The first limiting surface 4112 is used for the third limiting surface 4143 to abut against.

[0122] The elastic force of the first elastic member 415 is aligned with the axial direction L. One end of the first elastic member 415 abuts against the second limiting surface 4113, and the other end abuts against the fourth limiting surface 4144. The elastic force of the first elastic member 415 causes the trigger member 414 to tend to move away from the second limiting surface 4113, causing the abutting part 4141 to abut against the spherical ball 413a. The elastic force of the first elastic member 415 is continuously applied to the trigger member 414. Thus, without disconnecting the connection between the first connector 410 and the second connector 420, the trigger member 414 can be prevented from moving towards the second limiting surface 4113, thus avoiding the second groove 4142 from aligning with the spherical ball 413a.

[0123] The first limiting surface 4112 is used to abut against the third limiting surface 4143, which can prevent the trigger 414 from moving along the axial direction L to the second connector 420 and thus losing its limiting and triggering function on the ball 413a.

[0124] The connection process between the first connector 410 and the second connector 420 will be described below.

[0125] Please continue reading Figure 9 and Figure 12 As shown, the first piston assembly 412 includes a first valve housing 4122 and a first valve core 4123. The first valve core 4123 is located inside the first valve housing 4122 and is movable relative to the first valve housing 4122 along the axial direction L. The second connector 420 also includes a push rod 422 and a second valve core 423. The second valve core 423 is located radially R between the push rod 422 and the second body 421 and is movable relative to the second body 421 along the axial direction L. When the first stop member 413 is in the first position and the first stop member 413 is inserted into the first valve housing 4122 and the first body 411, when the first piston assembly 412 is inserted into the second body 421, the push rod 422 pushes the first valve core 4123 to move relative to the first valve housing 4122 so that the first connector 410 has a passage.

[0126] Specifically, the inner diameter of the end of the first valve housing 4122 facing the second connector 420 is smaller than the inner diameter of the other parts of the first valve housing 4122. When the first piston assembly 412 is not inserted into the second body 421, the first valve core 4123 blocks the end of the first valve housing 4122.

[0127] When the first piston assembly 412 is inserted into the second body 421, the push rod 422 pushes the first valve core 4123 to move, and the first valve core 4123 no longer blocks the end of the first valve housing 4122, thereby making the first connector 410 have a passage.

[0128] The first stop member 413 is inserted into the first valve housing 4122 and the first body 411, which can prevent the first valve housing 4122 from moving relative to the first body 411, so that the first piston assembly 412 can be smoothly inserted into the second body 421, which facilitates the push rod 422 to push the first valve core 4123, thereby enabling the first connector 410 to have a passage.

[0129] The first valve housing 4122 pushes the second valve core 423 to move relative to the second body 421 so that the second connector 420 has a passage.

[0130] Specifically, the inner diameter of the end of the second body 421 facing the first connector 410 is smaller than the inner diameter of the other parts of the second body 421. When the first piston assembly 412 is not inserted into the second body 421, the second valve core 423 blocks the end of the second body 421 facing the first connector 410.

[0131] When the first piston assembly 412 is inserted into the second body 421, the first valve housing 4122 pushes the second valve core 423 to move, and the second valve core 423 no longer blocks the end of the second body 421 facing the first connector 410, thereby allowing the second connector 420 to have a passage.

[0132] The first stop member 413 limits the first valve housing 4122 and the first body 411, which can prevent the first valve housing 4122 from moving relative to the first body 411, so that the first piston assembly 412 can be smoothly inserted into the second body 421, which facilitates the first valve housing 4122 to push the second valve core 423, thereby allowing the second connector 420 to pass through.

[0133] In other words, by limiting the first valve housing 4122 and the first body 411 by the first stop member 413, the first valve housing 4122 and the first body 411 are kept stationary. When the first connector 410 and the second connector 420 are plugged in, both the first connector 410 and the second connector 420 can be connected normally.

[0134] Please continue reading Figure 10 and Figure 13As shown, the first piston assembly 412 further includes a second elastic element 4124, which abuts against the first valve housing 4122 and the first valve core 4123; the second connector 420 includes a third elastic element 424, which abuts against the second body 421 and the second valve core 423; when the first stop member 413 is in the second position, under the elastic force of the second elastic element 4124 and the third elastic element 424, the first piston assembly 412 can move axially L relative to the first body 411 in a direction away from the second body 421 to exit from the second connector 420, so that the first connector 410 and the second connector 420 are disconnected.

[0135] Push rod 422, first valve core 4123, second elastic element 4124 and first valve housing 4122 abut against each other in sequence. When the first stop element 413 no longer limits the first valve housing 4122 and the first body 411, push rod 422 remains stationary. Under the action of part of the elastic force of the second elastic element 4124, the first piston assembly 412 can move away from the second connector 420.

[0136] The second body 421, the third elastic element 424, the second valve core 423 and the first valve shell 4122 abut against each other in sequence. When the first stop element 413 no longer limits the first valve shell 4122 and the first body 411, the second body 421 remains stationary. Under the action of part of the elastic force of the third elastic element 424, the first piston assembly 412 can move away from the second connector 420.

[0137] By setting the second elastic element 4124 and the third elastic element 424, after the first stop element 413 no longer limits the first valve shell 4122 and the first body 411, the first piston assembly 412 can be moved away from the second connector 420 by relying on the elastic force of the second elastic element 4124 and the third elastic element 424. Thus, it is possible to avoid manually or by external force pushing the first piston assembly 412 to move.

[0138] It should be noted that, under the elastic force of the second elastic member 4124, the first valve core 4123 moves to the end of the first valve housing 4122 facing the second connector 420, thereby sealing the first valve housing 4122 and preventing coolant overflow from the first connector 410. Under the elastic force of the third elastic member 424, the second valve core 423 moves to the end of the second body 421 facing the first connector 410, thereby sealing the second body 421 and preventing coolant overflow from the second connector 420. Thus, the second elastic member 4124 can simultaneously drive the first piston assembly 412 to move and also cause the first valve core 4123 to seal the first valve housing 4122, with one component simultaneously driving the execution of two actions; the third elastic member 424 can simultaneously drive the first piston assembly 412 to move and also cause the second valve core 423 to seal the second body 421, with one component simultaneously driving the execution of two actions, further improving the timeliness of disconnection when the first connector 410 and the second connector 420 are disconnected.

[0139] Please continue reading Figures 12 to 16 As shown, the first body 411 has a fifth limiting surface 4114, and the first piston assembly 412 has a sixth limiting surface 4125; the first connector 410 also includes a fourth elastic element 416, which abuts between the fifth limiting surface 4114 and the sixth limiting surface 4125.

[0140] The elastic force of the fourth elastic element 416 is aligned with the axial direction L. One end of the fourth elastic element 416 abuts against the fifth limiting surface 4114, and the other end abuts against the sixth limiting surface 4125. After the first connector 410 and the second connector 420 are disconnected, for example, after the first connector 410 is removed from the housing 210 of the node 200, the elastic force of the fourth elastic element 416 causes the first piston assembly 412 to tend to move away from the fifth limiting surface 4114, aligning the first groove 4121a on the first piston assembly 412 with the through groove 4111a on the first body 411. The spherical ball 413a enters the through groove 4111a and the first groove 4121a to limit the first piston assembly 412 and the first body 411, thereby allowing the first connector 410 to return to a state where it can be inserted with the second connector 420. This avoids the need for manual application of external force to return the first connector 410 to a state where it can be inserted with the second connector 420.

[0141] Understandably, the sum of the elastic forces of the second elastic element 4124 and the third elastic element 424 is greater than the elastic force of the fourth elastic element 416. Therefore, when the first connector 410 is disconnected from the second connector 420, the elastic forces of the second elastic element 4124 and the third elastic element 424 can overcome the elastic force of the fourth elastic element 416, causing the first piston assembly 412 to move toward the side of the fourth elastic element 416.

[0142] Figure 20 This is a schematic diagram of the electrical connection relationship of a computing device provided in an embodiment of this application.

[0143] See Figure 20 As shown, the computing device 10 also includes a controller 500. A leak detector 240 is installed in the node 200 and is electrically connected to the controller 500. A trigger 414 is used to trigger the first stop 413 to switch between a first position and a second position. When the leak detector 240 detects a leak in the node 200, the controller 500 controls the trigger 414 to switch the first stop 413 from the first position to the second position, and the first connector 410 and the second connector 420 are disconnected.

[0144] A leak detector 240 can be installed in node 200. The leak detector 240 can be fixed to the bottom and side walls of housing 210, and is positioned near the cooling module 230. A controller 500 can be installed in the housing 210 of node 200; for example, the controller 500 can be positioned near the first connector 410 within housing 210. The controller 500 can be a microcontroller unit (MCU) or a programmable logic device (PLD). The controller 500 can also be a baseboard management controller (BMC).

[0145] A drive unit can be installed in the housing 210. The drive unit can be a solenoid valve, which can be positioned in the housing 210 near the first connector 410. Alternatively, the drive unit can be a motor, which is connected to the trigger 414 on the first connector 410 via a connecting rod.

[0146] The leak detector 240 is electrically connected to the controller 500, and the driver can also be electrically connected to the controller 500. The connection between the leak detector 240 and the driver and the controller 500 can be wired or wireless.

[0147] When leakage occurs at a certain node 200, the leakage detector 240 detects the leakage and feeds the leakage information back to the controller 500. Based on the leakage information, the controller 500 controls the drive to move. When the drive is a solenoid valve, the controller 500 controls the solenoid valve to close, and the suction force generated by the solenoid valve drives the trigger 414 to move. When the drive is a motor, the controller 500 controls the motor to run, and the motor drives the trigger 414 to move through the connecting rod. The trigger 414 moves until the second groove 4142 on the trigger 414 aligns with the ball bearing 413a. The ball bearing 413a disengages from the first groove 4121a and enters the second groove 4142 (that is, the ball bearing 413a is in the second position). The first piston assembly 412 moves axially L relative to the first body 411 to the first connector 410 and disconnects from the second connector 420.

[0148] By setting up a leak detector 240 and a controller 500, and making the leak detector 240 electrically connected to the controller 500, when the leak detector 240 detects a leak, the controller 500 can respond in a timely manner and control the trigger 414 to act, which further improves the timeliness when the first connector 410 and the second connector 420 are disconnected.
