Description

Technical Field

[0001] This invention relates to the field of server technology, and more particularly to a server. Background Technology

[0002] Internet service providers, enterprise platforms, and research institutions all require significant computing power. The operational platforms that support these needs, including storage, computing, and networking, are called data centers. Furthermore, with the increasing demand for information and communication technologies (ICTs) in modern society, data centers have developed rapidly. This has led to a shift in the density of ICT equipment within data centers from low to high. High-density ICT equipment generates substantial heat during operation, necessitating cooling systems in data centers to ensure the proper functioning of the ICT equipment.

[0003] In related technologies, data centers include multiple mainframe servers and / or at least one server, each mainframe server comprising multiple computing nodes and multiple cold plates. A single computing node, when used independently, can also be referred to as a server. The components of each computing node contact the cold plate and exchange heat with the liquid cooling medium within the cold plate, thereby achieving liquid cooling. The output end of the cold plate is connected to the input end of a cooling medium distribution device via an outlet pipe, and the input end of the cold plate is connected to the output end of the cooling medium via an inlet pipe. However, the flow rate of the cooling medium within the cold plate cannot be flexibly adjusted according to the heat dissipation of the components, resulting in low energy efficiency of the cooling medium.

[0004] Therefore, how to control the flow rate of liquid cooling medium without affecting the heat dissipation of components has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a server that can flexibly adjust the flow rate of liquid cooling medium according to the heat consumption of different heat-generating devices, which helps to improve the energy efficiency of the cooling medium.

[0006] This application provides a server, including a heat dissipation device and at least one server node. Each server node includes at least one heat-generating device. The heat dissipation device includes a first pipe, a second pipe, at least one flow regulating valve, and at least one male connector. Each server node also has a liquid inlet and a liquid outlet. The liquid outlet is connected to the second pipe, the liquid inlet is connected to the output end of the flow regulating valve, and the input end of the flow regulating valve is connected to the first pipe through the male connector. The flow regulating valve controls the flow rate of the cooling medium entering the server node, and the cooling medium is used for heat exchange with the heat-generating device.

[0007] The server in this embodiment of the application can regulate the flow rate of the cooling medium entering the server node by setting a flow regulating valve. This allows for flexible adjustment of the cooling medium flow rate based on the heat consumption of the heat-generating components, thus helping to improve the energy efficiency of the cooling medium. Furthermore, the flow regulating valve is connected to the first pipe via a male connector. The function of the input end of the flow regulating valve is similar to that of the female connector, allowing for quick connection between the flow regulating valve and the first pipe by aligning it with the male connector.

[0008] In one possible implementation, the flow regulating valve includes a valve body and a connector, the connector communicating with the male connector. The valve body is fastened to the connector, and the valve body has a flow channel hole. One end of the flow channel hole communicates with the liquid inlet, and the other end communicates with the connector. The valve body controls the area of ​​communication between the flow channel hole and the connector. The input end of the connector is detachably connected to the male connector. The connector functions similarly to the female connector, allowing it to be plugged into the male connector for quick connection, thereby increasing the connection speed between the flow regulating valve and the first pipeline. Since the valve body opening is adjustable, it can regulate the flow rate of the cooling medium. Therefore, for different heat-generating devices, the flow rate of the cooling medium can be flexibly adjusted according to the heat consumption of the heat-generating device, improving energy efficiency and contributing to ultimate energy efficiency control.

[0009] In one possible implementation, the valve body includes a drive assembly, a valve body assembly, a valve core, and a valve seat. The valve body assembly has a receiving cavity and three openings communicating with the receiving cavity: a first opening, a second opening, and a third opening. The second opening communicates with the connector portion, and the third opening communicates with the liquid inlet. One end of the valve core is located within the receiving cavity and is rotatably connected to the valve body assembly. The other end of the valve core is located outside the receiving cavity through the first opening and is driveably connected to the drive assembly. A flow channel hole is disposed through the valve core, and the drive assembly drives the valve core to rotate, switching the valve body between an open and closed state. When the valve body is in the open state, the second opening and the third opening communicate through the flow channel hole. When the valve body is in the closed state, the second opening and the third opening are not communicating. The valve seat is located within the receiving cavity and seals the connection between the second opening and the flow channel hole. This valve body structure allows for adjustable valve body opening, enabling the flow control valve to regulate the flow rate of the cooling medium.

[0010] In one possible implementation, when the valve body is in the open state, the drive assembly is also used to drive the valve core to rotate and control the area of ​​the flow channel hole communicating with the second opening, so as to adjust the flow rate of the cooling medium according to the heat generated by the heat-generating device.

[0011] In one possible implementation, the valve core has a flow channel hole penetrating through it, and the valve seat has a through port penetrating through it. One end of the through port communicates with a second opening, and the other end of the through port communicates with one end of the flow channel hole. When the valve body is in the open state, one end of the flow channel hole communicates with the second opening through the through port, and the other end of the flow channel hole communicates with the third opening through the receiving cavity, thus connecting the second opening and the third opening. When the valve body is in the closed state, the flow channel hole and the through port are not connected, thereby disconnecting the second opening from the third opening. Through the interaction of the flow channel hole and the through port, the second opening and the third opening can be connected or disconnected, thus allowing the valve body to be configured in either a closed or open state.

[0012] In one possible implementation, the drive assembly includes a motor and a transmission mechanism. The motor is securely mounted on the outer wall of the valve body assembly and is connected to the other end of the valve core via the transmission mechanism. The motor drives the valve core to rotate around its own axis via the transmission mechanism. This rotation of the valve core by the motor via the transmission mechanism allows for switching between an open and closed state of the valve body and also enables remote control.

[0013] In one possible implementation, the connector includes a hollow connector base, a piston, and a spring. One end of the connector base is securely connected to the valve body and communicates with the flow channel of the valve body. The other end of the connector base is detachably connected to the male connector. An abutment portion is provided at the end of the connector base connected to the male connector. The piston and the spring are disposed within the connector base and located between the abutment portion and the valve body, with both ends of the spring abutting against the piston and the valve body respectively. The piston is slidably connected to the inner wall of the connector base. When the male connector leaves the connector base, the piston abuts against the abutment portion and forms a sealing connection, preventing the cooling medium from entering the valve body through the connector base. When the male connector is inserted into the connector base, a gap exists between the piston and the abutment portion, allowing the interior of the connector base to be open, and the cooling medium can pass through the connector base into the valve body. This configuration allows the connector to function similarly to the female connector, enabling quick connection between the connector and the male connector.

[0014] In one possible implementation, a through-flow channel is provided on the end face of the piston facing the valve body. When the male connector is inserted into the connector base, the cooling medium enters the connector base through the through-flow channel. The through-flow channel allows the cooling medium within the male connector to pass through the connector base and enter the valve body when the connector is in a conductive state.

[0015] In one possible implementation, when the male connector leaves the connector base, a portion of the piston is inserted into the abutment portion and sealed to the inner wall of the abutment portion. This arrangement enables a sealed connection between the abutment portion and the piston, preventing the cooling medium from leaking from the connector base.

[0016] In one possible implementation, the connector further includes a second seal fitted onto the piston. When the male connector is disengaged from the connector base, the second seal abuts against the inner walls of both the piston and the abutment portion. When the connector is in the closed state, the second seal abuts against the inner walls of both the piston and the abutment portion. The second seal enhances the sealing effect between the abutment portion and the piston.

[0017] In one possible implementation, a guide opening is defined on the inner wall between the outer end face of the abutment portion and the end face of the connector base that connects to the male connector. The outer end face of the abutment portion is the end face of the abutment portion away from the valve body. The guide opening is used to position the relative positions of the connector base and the male connector when the male connector is inserted into the connector base, facilitating blind insertion of the flow control valve and the male connector.

[0018] In one possible implementation, the connector further includes a first seal, which is securely mounted within the connector base and abuts against the end of the connector base where it connects to the male connector. When the male connector is inserted into the connector base, the first seal is fitted onto the male connector and abuts against both the male connector and the connector base. The first seal improves the sealing effect of the male connector and the connector portion, helping to prevent cooling medium leakage.

[0019] In one possible implementation, the outer end face of the abutment portion is flush with the end face of the connector base connected to the male connector. A snap-fit ​​portion is provided on the outer wall of the connector base, which engages with a mating portion provided on the male connector. Through the mutual engagement of the snap-fit ​​portion and the mating portion, the male connector can be snapped into place with the connector portion, thereby enabling automatic connection between the flow regulating valve and the male connector.

[0020] In one possible implementation, the heat dissipation device further includes at least one shut-off valve disposed between the liquid outlet and the second pipe, for controlling the connection between the liquid outlet and the second pipe. The shut-off valve functions as a switch, disconnecting the cooling medium in case of leakage.

[0021] In one possible implementation, the heat dissipation device further includes at least one quick connector, through which the liquid outlet communicates with the second pipe. The quick connector includes a female end and a male end, the male end being detachably connected to the female end. The male end is used to communicate with either the second pipe or the liquid outlet, and the female end is used to communicate with either the liquid outlet or the second pipe. The quick connector enables a rapid connection between the liquid cooling outlet and the second pipe.

[0022] In one possible implementation, the outlet is also connected to the second pipe via the flow regulating valve and the male connector. Specifically, the outlet is connected to the input of the flow regulating valve, and the output of the flow regulating valve is connected to the second pipe via the male connector. This configuration allows control of the flow rate of the cooling medium exiting the server node, contributing to improved control accuracy.

[0023] In one possible implementation, the server node further includes a cold plate located above the at least one heat-generating device. The cold plate has a cavity for containing the liquid cooling medium, and the liquid inlet and outlet are disposed on the cold plate and communicate with the cavity. This configuration can meet the heat dissipation requirements of the heat-generating device.

[0024] In one possible implementation, the server node further includes a housing having a cavity for containing the liquid cooling medium. The inlet and outlet are located on the housing and communicate with the cavity. The at least one heat-generating device is located within the cavity. This configuration satisfies the heat dissipation requirements of the heat-generating device.

[0025] In one possible implementation, the server node further includes a housing and at least one nozzle. The housing has a cavity for containing the liquid cooling medium. An inlet and an outlet are disposed on the housing and communicate with the cavity. The at least one heat-generating device and the at least one nozzle are located within the cavity. The nozzle is connected to the inlet and is used to spray the cooling medium onto the at least one heat-generating device. This configuration satisfies the heat dissipation requirements of the heat-generating device and reduces the amount of cooling medium used.

[0026] In one possible implementation, the server further includes a cooling medium distribution device. The output of the cooling medium distribution device is connected to the first pipe, and the input of the cooling medium distribution device is connected to the second pipe. The cooling medium distribution device is used to deliver liquid cooling medium to the server node, thereby enabling the cooling medium to be recycled.

[0077] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0078] To facilitate understanding, the relevant technical terms involved in the embodiments of this application will first be explained and described.

[0079] Liquid cooling: a method that does not rely on any fans or chillers, but relies entirely on liquid to carry heat to the cooling tower for heat dissipation.

[0080] Cold plate: A sealed radiator that can accommodate liquid flow, typically bonded to the heating element via a thermally conductive interface material to dissipate heat from the heating element. The cold plate has a cavity to contain the liquid.

[0081] Two-phase heat dissipation: The same working fluid changes from liquid to gas, absorbing a large amount of heat. This heat dissipation method utilizes the phase change between gas and liquid.

[0082] Data center 1000 is a globally collaborative network of specific devices used to transmit, accelerate, display, compute, and store data information over internet infrastructure. This application provides an embodiment of a data center 1000; see [link to embodiment]. Figure 1 As shown, data center 1000 may include server room 200, see [link / reference] Figure 2 As shown, the computer room 200 contains at least one equipment cabinet 300. The number of equipment cabinets 300 may include, but is not limited to, the three shown in the figure, for example, 50 to 100 equipment cabinets 300. The computer room 200 is equipped with a cooling system that provides a good operating environment for the equipment cabinets 300. In this embodiment, the specific structure and working principle of the cooling system within the computer room 200 are not described in detail.

[0083] The multiple equipment cabinets 300 may include one or more of the following: communication cabinets, power supply cabinets, server 100, or cooling cabinets for dissipating heat from server 100. Server 100 may be a rack-mount server 100, a server rack, etc., and includes a cooling device 10 and at least one server node 20. It should be noted that server 100 may also include a frame for housing the cooling device 10, which dissipates heat from at least one server node 20. This frame may be the cabinet of server 100. When there is only one server node 20, the cooling device 10 delivers liquid cooling medium to that server node 20 to dissipate heat. When there are multiple server nodes 20, the cooling device 10 can deliver liquid cooling medium to all server nodes 20 to dissipate heat from all server nodes 20.

[0084] Server node 20 can be a computing device, storage device, power supply device, switching device, battery device, or communication device, etc., without specific restrictions.

[0085] When there are multiple server nodes 20, all server nodes 20 can use cold plates 17 for single-phase liquid cooling, achieving single-phase full liquid cooling. For example Figure 3A This is a schematic diagram of a server 100 using single-phase liquid cooling, as provided in an embodiment of this application. Figure 3AIn this configuration, each heat-generating component 21 of the server node 20 is paired with a cold plate 17, allowing the heat-generating component 21 to dissipate heat through the cold plate 17. Alternatively, in some instances, the electronic components in the server node 20 can be completely immersed in a cooling medium to achieve single-phase liquid cooling, such as... Figure 3B , Figure 3B This is a schematic diagram of another server 100 provided in this application embodiment, using single-phase liquid cooling for heat dissipation, with the circuit board 22 immersed in the cooling medium. Alternatively, in some instances, all server nodes 20 may employ two-phase cooling. For example... Figure 3C This is a schematic diagram of a server 100 with two-phase heat dissipation provided in an embodiment of this application. (Refer to...) Figure 3C Each server node 20 has a nozzle 23 above its circuit board 22, which sprays liquid cooling medium onto the circuit board 22. The heat generated by the heat-generating device 21 on the circuit board 22 causes the cooling medium in the server node 20 to change from liquid to gas and exit from the liquid outlet 172 of the server node 20. Alternatively, the liquid cooling medium can enter from the liquid inlet 171 of the server node 20.

[0086] It should be noted that, in addition to the heat dissipation scenarios described above, in some instances where there are multiple server nodes 20, some server nodes 20 can employ single-phase liquid cooling while others can employ two-phase cooling. For example, computing devices may use two-phase cooling, while power supply devices, battery devices, and switching devices may use cold plates 17 for single-phase liquid cooling. Alternatively, some computing devices may use two-phase cooling while others use single-phase liquid cooling.

[0087] Taking server node 20 entirely using cold plates 17 as an example, in related technologies, the heat-generating components of the server node undergo single-phase liquid cooling via cold plates. The cooling medium within the cold plate exchanges heat with the heat-generating components, and the cooling medium flows out from the outlet of the cold plate, carrying away the heat generated by the heat-generating components. The inlet of the cold plate is connected to a first pipe via a quick connector. The outlet of the cold plate is connected to a second pipe via a quick connector. The quick connector may include a male connector and a female connector. The female connector is connected to either the outlet or the inlet. The male connector is connected to either the first or the second pipe. The male and female connectors can be interlocked to connect or disconnect them. However, because the pipe section between the quick connector and the cold plate is located within the server node and close to the server's individual boards, if the pipe between the quick connector and the cold plate breaks or leaks, the cooling medium in the pipe cannot be shut off in time, leading to damage to the individual boards within the server node and consequently, damage to the server. In this context, a single board refers to a module containing components such as processors, resistors, capacitors, or power supplies. Furthermore, the heat dissipation of heat-generating components within different server nodes varies, requiring different flow rates of cooling media. The lack of flow control mechanisms in the cooling media pipelines results in low utilization of the cooling media, leading to low energy efficiency and hindering optimal energy control. Additionally, the connection of quick-connect fittings to the inlet or outlet of the cold plate via pipes increases the number of assembly steps for the heat dissipation device, thus increasing assembly time, and also raises the risk of cooling media leakage.

[0088] In view of this, taking the use of a cold plate 17 for heat dissipation as an example, this application provides a server 100, which may include a heat dissipation device 10 and at least one server node 20. The heat dissipation device 10 is used to dissipate heat from the server node 20. (Refer to...) Figure 3AThe heat dissipation device 10 includes at least a cold plate 17, a flow regulating valve 16, a shut-off valve 15, and a quick connector 14. The cold plate 17 is used to contact the heat-generating device 21, allowing the liquid cooling medium within the cold plate 17 to exchange heat with the heat-generating device 21. The inlet 171 of the cold plate 17 is connected to the output of the flow regulating valve 16, and the outlet 172 of the cold plate 17 is connected to the input of the shut-off valve 15. The shut-off valve 15 is used to disconnect the flow of the cooling medium between the cold plate 17 and the quick connector 14. The output of the shut-off valve 15 is connected to the input of the second pipe 13 via the quick connector 14. The input of the flow regulating valve 16 is connected to the output of the first pipe 12 via the male connector 141 of the quick connector 14. Additionally, the flow regulating valve 16 may include a valve body 30 and a connector 40. The input of the valve body 30 is connected to the output of the connector 40, and the output of the valve body 30 is connected to the inlet 171 of the cold plate 17. The input end of connector 40 is detachably connected to male connector 141. Connector 40 functions similarly to female connector 142, interlocking with male connector 141 to achieve quick connection between flow regulating valve 16 and male connector 141, thereby increasing the connection speed between flow regulating valve 16 and first pipe 12. Since the opening of valve body 30 is adjustable, it can be used to regulate the flow rate of cooling medium. For different heat-generating devices 21, the flow rate of cooling medium can be flexibly adjusted according to the heat consumption of the heat-generating device 21, improving energy efficiency and contributing to ultimate energy efficiency control. Furthermore, in the event of cooling medium leakage, the opening of valve body 30 can be reduced to zero, thus preventing further leakage and damage to the circuit board. Furthermore, since the input end of the flow regulating valve 16 is connected to the output end of the first pipe 12, no additional pipe is needed between the flow regulating valve 16 and the first pipe 12. This reduces the number of assembly steps between the first pipe 12 and the flow regulating valve 16, and the number of times the heat dissipation device 10 is assembled, thus improving assembly efficiency. Also, the absence of an additional pipe between the flow regulating valve 16 and the first pipe 12 reduces the risk of cooling medium leakage.

[0089] Below is a specific example of server 100, for reference. Figure 3AThe server 100 may include a heat dissipation device 10 and four server nodes 20. Each server node 20 may include a heat-generating device 21. The heat dissipation device 10 may include a cooling medium distribution device 11, a first pipe 12, a second pipe 13, male terminals 141 of four quick connectors 14, four cold plates 17, four shut-off valves 15, and four quick connectors 14. The input end of the cooling medium distribution device 11 is connected to the output end of the second pipe 13, and the output end of the cooling medium distribution device 11 is connected to the input end of the first pipe 12. Each flow regulating valve 16 includes a valve body 30 and a connector 40. The output end of the valve body 30 is connected to the liquid inlet 171 of the cold plate 17, and the valve body 30 is used to control the flow rate of the cooling medium. The connector 40 is connected to the first pipe 12 through the male terminal 141, and the connector 40 and the male terminal 141 can form a quick connector 14. The liquid outlets 172 of the four cold plates 17 are respectively connected to the input ends of the four shut-off valves 15. The outputs of the four shut-off valves 15 are connected to the input of the second pipe 13 via four quick connectors 14. Therefore, liquid cooling medium flows from the input of the cooling medium distribution device 11 into the first pipe 12. The cooling medium in the first pipe 12 then flows through the male connector 141 and the flow regulating valve 16 from the inlet 171 into the cold plate 17. The cooling medium in the cold plate 17 exits from the outlet 172 and enters the second pipe 13 via the shut-off valves 15 and quick connectors 14. The cooling medium in the second pipe 13 then enters the cooling medium distribution device 11, thus achieving cooling medium circulation. The cooling medium in the cold plate 17 exchanges heat with the heating element 21, thus changing the temperature of the heating element 21 from low to high while simultaneously lowering its temperature. The high-temperature cooling medium exits from the outlet 172 and finally enters the cooling medium distribution device 11. The cooling medium distribution device 11 can change the high-temperature cooling medium to a low-temperature cooling medium and then return the low-temperature cooling medium to the cold plate 17, thereby achieving cooling medium recycling.

[0090] Because the quick connector 14 is a tool-free connector that allows for pipe connection or disconnection, it improves the speed of pipe connection or disconnection. "Tool-free" means that the quick connector 14's structure alone is sufficient for pipe connection or disconnection, without the need for additional tools. Furthermore, the quick connector 14 may include a male connector 141 and a female connector 142. The male connector 141 is used for detachable connection with the female connector 142. When the male connector 141 and female connector 142 are properly mated, they are connected; when they are not mated, they are not connected. Therefore, when the shut-off valve 15 is connected to the second pipe 13 via the quick connector 14, the male connector 141 can connect to either the output of the shut-off valve 15 or the input of the second pipe 13. The female connector 142 can connect to either the output of the shut-off valve 15 or the input of the second pipe 13.

[0091] In some embodiments, quick connector 14 may be omitted.

[0092] It should be noted that the cooling medium distribution device 11 can be located inside the server 100, or it can be located outside the server 100. In addition, multiple servers 100 can share the same cooling medium distribution device 11, which is not restricted here.

[0093] Continue to refer to Figure 3A The cooling medium distribution device 11 may include a heat exchanger 111 and a transfer pump 112. The input end of the heat exchanger 111 is connected to the output end of the second pipe 13, and the output end of the heat exchanger 111 is connected to the input end of the transfer pump 112. The output end of the transfer pump 112 is connected to the input end of the first pipe 12. The heat exchanger 111 is used to change the high-temperature cooling medium flowing from the cold plate 17 into the heat exchanger 111 into a low-temperature cooling medium. The transfer pump 112 can transport the low-temperature cooling medium obtained by the heat exchanger 111 to the cold plate 17 through the first pipe 12. Therefore, through the cooperation of the transfer pump 112 and the heat exchanger 111, the recycling of the liquid cooling medium can be realized.

[0094] It should be noted that the number of server nodes 20 is not limited to two; there must be at least one server node 20. For example, in some examples, the number of server nodes 20 is one or five. Furthermore, the number of heating devices 21 included in each server node 20 is not limited to two; each server node 20 includes at least one heating device 21. When there are multiple server nodes 20, the number of heating devices 21 in all server nodes 20 can be the same or different, and no specific limitation is imposed here.

[0095] It is understandable that the number of cold plates 17 is the same as the number of heating elements 21. Therefore, when there are multiple heating elements 21, there are also multiple cold plates 17, which correspond one-to-one with the multiple heating elements 21. Of course, in some examples, one heating element 21 can also correspond to multiple cold plates 17, for example, one heating element 21 corresponds to two cold plates 17.

[0096] It is understood that the number of shut-off valves 15, flow regulating valves 16, quick connectors 14, and male connectors 141 installed on the first pipe 12 are all the same as the number of cold plates 17. Each cold plate 17 corresponds to one male connector 141, one shut-off valve 15, one flow regulating valve 16, and one quick connector 14.

[0097] Understandably, the shut-off valve 15 is similar to a switch that controls the connection or disconnection of the pipeline between the quick connector 14 and the outlet 172 of the cold plate 17.

[0098] When a cooling medium leaks, adjusting the opening of the regulating valve body 30 and closing the shut-off valve 15 prevents the cooling medium from entering or flowing out of the cold plate 17, thus stopping the cooling medium from continuing to circulate and achieving the shut-off purpose. This also prevents the cooling medium from damaging the single board of the server node 20. However, in some examples, the shut-off valve 15 may not be provided. The outlet 172 of the cold plate 17 is connected to the input end of the second pipe 13 through the quick connector 14. In this case, when a cooling medium leaks, the opening of the regulating valve body 30 of the flow control valve 16 becomes 0, preventing the cooling medium from flowing into the cold plate 17 and stopping the cooling medium from continuing to circulate, thus achieving the shut-off purpose.

[0099] Since the opening degree of the valve body 30 of the flow regulating valve 16 is adjustable, the flow rate of the cooling medium can be adjusted according to the heat consumption of different heat-generating devices 21. This allows for flexible adjustment of the cooling medium flow rate based on the heat consumption of different server nodes 20, contributing to achieving maximum energy efficiency. Furthermore, since the flow regulating valve 16 is connected to the first pipe 12 via the male connector 141, the risk of cooling medium leakage can be reduced, and assembly efficiency can be improved. Because the function of the connector 40 is similar to that of the female connector 142, the connector 40 can be inserted into the male connector 141, which helps to increase the connection speed between the flow regulating valve 16 and the first pipe 12.

[0100] Figure 4 This is a cross-sectional view of the valve body of a flow regulating valve provided in this application embodiment, in the open state. Figure 5 This is a cross-sectional view of the valve body of a flow regulating valve provided in this application embodiment in the closed state.

[0101] refer to Figure 4The flow control valve 16 may include a valve body portion 30 and a connector portion 40. The valve body portion 30 may include a drive assembly 31, a valve body assembly 32, a valve core 33, and a valve seat 34. The valve body assembly 32 has a receiving cavity 35 and has a first opening 36, a second opening 37, and a third opening 38 communicating with the receiving cavity 35. The third opening 38 serves as the output end of the flow control valve 16. One end of the valve core 33 passes through the first opening 36 and is located within the receiving cavity 35, and one end of the valve core 33 is rotatably connected to the valve body assembly 32. The other end of the valve core 33 is rotatably and sealingly connected to the valve body assembly 32 at the first opening 36, and the other end of the valve core 33 is drively connected to the drive assembly 31 located outside the receiving cavity 35, wherein the drive assembly 31 can drive the valve core 33 to rotate within the receiving cavity 35. The valve seat 34 is provided with a through port 341 penetrating the valve seat 34, thereby giving the valve seat 34 an annular structure. The valve seat 34 is positioned near the second opening 37 and is sealed to both the valve body assembly 32 and the valve core 33. The through port 341 communicates with the second opening 37. The valve core 33 has a flow channel hole 331 that penetrates the valve core 33. Through the cooperation of the valve seat 34 and the valve core 33, the flow channel hole 331 can be connected to or disconnected from the through port 341. Thus, the second opening 37 can be connected to or disconnected from the third opening 38 through the through port 341, the flow channel hole 331, and the receiving cavity 35.

[0102] The size of the opening at the end of the second opening 37 that connects to the through opening 341 can be equal to or smaller than the size of the through opening 341. Alternatively, the size of the opening at the end of the second opening 37 that connects to the through opening 341 can also be equal to the size of the through opening 341, but the size of the opening at the end of the second opening 37 that connects to the through opening 341 must be smaller than the size of the valve seat 34 to prevent the second opening 37 from connecting to the receiving cavity 35. The size of the valve seat 34 refers to the edge dimension of the valve seat 34; for example, when the valve seat 34 is circular, the size refers to the outer diameter of the valve seat.

[0103] Driven by the drive assembly 31, the valve body 30 can rotate around its own axis, allowing the flow channel hole 331 to communicate with or not communicate with the second opening 37. Furthermore, the second opening 37 can communicate with or not communicate with the third opening 38 through the through port 341, the flow channel hole 331, and the receiving cavity 35, allowing the valve body 30 to be configured in an open state (e.g., ...). Figure 4 (as shown) and off state (as shown) Figure 5 (As shown). In addition, by changing the rotation angle of the valve core 33, the communication area between the flow channel hole 331 and the through port 341 can be changed, and thus the communication area between the flow channel hole 331 and the second opening 37 can be changed, so that the opening degree of the valve body 30 can be adjusted and the flow rate of the cooling medium can be regulated.

[0104] refer to Figure 4 When the valve body 30 is in the open state, the second opening 37 is connected to one end of the flow channel hole 331 through the through port 341 of the valve seat 34, and the other end of the flow channel hole 331 is connected to the third opening 38 through the receiving cavity 35, so that the second opening 37 and the third opening 38 are connected, and the cooling medium flowing in from the second opening 37 can flow out from the third opening 38.

[0105] refer to Figure 5 When the valve body 30 is in the closed state, the valve core 33 seals the through port 341 of the valve seat 34, so that the flow channel hole 331 is not connected to the through port 341. As a result, the through port 341 of the valve seat 34 cannot connect with the third opening 38 through the flow channel hole 331 and the receiving cavity 35. Consequently, the second opening 37 and the third opening 38 are not connected, and the cooling medium flowing in from the second opening 37 cannot flow out from the third opening 38.

[0106] Continue to refer to Figure 4 A hollow pagoda-shaped connector 324 may extend from the outer wall of the valve body assembly 32, with one end of the pagoda-shaped connector 324 communicating with the third opening 38. The pagoda-shaped connector 324 can be inserted into a pipe and securely connected to it, which helps to improve the connection efficiency between the pipe and the third opening 38. Of course, the pagoda-shaped connector 324 may not be provided. For example, in some examples, a tubular portion extends from the outer wall of the valve body assembly 32, with external threads tapped on the outer wall of the tubular portion. One end of the tubular portion communicates with the third opening 38, and the tubular portion is used for threaded connection with the pipe.

[0107] Continue to refer to Figure 4 The valve body assembly 32 may include a valve body 321 and a valve cover 322. The valve cover 322 is fitted onto the valve body 321 and is securely connected to the valve body 321. The inner wall of the valve cover 322 and the inner wall of the valve body 321 together define a receiving cavity 35. A first opening 36, a second opening 37, and a third opening 38 are all provided on the valve body 321 and communicate with the receiving cavity 35. In addition, the first opening 36 is disposed opposite to the valve cover 322 along the axial direction of the valve core 33, so that the valve core 33 passes through the first opening 36, and the opposite ends of the valve core 33 are rotatably connected to the valve body 321 and the valve cover 322, respectively. The second opening 37 and the third opening 38 are provided on the opposite ends of the valve body 321.

[0108] Continue to refer to Figure 4 The valve cover 322 has a rotating groove 3221 on its inner side facing the valve core 33 for the valve core 33 to be inserted. The rotating groove 3221 is used to support the valve core 33 and realize the rotatable connection between the valve cover 322 and the valve core 33.

[0109] Continue to refer to Figure 4A limiting groove 3222 can be provided on the inner side of the valve cover 322 facing the valve core 33. The valve core 33 is provided with a limiting part 332 that inserts into the limiting groove 3222 and can slide within the limiting groove 3222. Through the cooperation of the limiting groove 3222 and the limiting part 332, the rotation range of the valve core 33 can be limited to prevent the valve core 33 from rotating 360 degrees. The limiting groove 3222 is an arc-shaped groove, and the center of the limiting groove 3222 coincides with the rotation axis of the valve core 33.

[0110] Continue to refer to Figure 4 In order to improve the sealing effect between the valve seat 34 and the second opening 37, a fourth annular groove 323 is provided on the side wall of the valve body 321 for the valve seat 34 to be partially inserted.

[0111] Continue to refer to Figure 4 To improve the sealing effect between the second opening 37 and the valve seat 34, the valve body 30 further includes a fourth sealing element 39. The fourth sealing element 39 is inserted into the fourth annular groove 323 and abuts against the inner wall of the fourth annular groove 323 and the valve seat 34 respectively.

[0112] Continue to refer to Figure 4 The drive assembly 31 may include a motor 311 and a transmission mechanism 312. The motor 311 is securely mounted on the outer wall of the valve body assembly 32. The transmission mechanism 312 may include a first gear 3121 and a second gear 3122. The first gear 3121 is mounted on the output shaft of the motor 311. The second gear 3122 is mounted on the end of the valve core 33 located outside the receiving cavity 35 and meshes with the first gear 3121. In addition, the drive assembly 31 may also include a control circuit board 22 (not shown in the figure), which is electrically connected to the motor 311. The control circuit board 22 can control the rotation of the motor 311, thereby controlling the rotation angle of the valve core 33. Therefore, by means of the drive assembly 31, the valve core 33 can be rotated about its own axis, and the rotation angle of the valve core 33 can be controlled, thereby controlling the communication area between the flow channel hole 331 and the second opening 37, thereby controlling the opening size of the valve body 30. In addition, since the rotation of the valve core 33 is controlled by the motor 311, the rotation of the motor 311 can be remotely controlled to remotely adjust the flow rate of the cooling medium and disconnect the flow of the cooling medium.

[0113] It should be noted that, in addition to gear transmission, the transmission mechanism 312 can also use chain transmission, belt transmission, or other transmission methods. Furthermore, besides being connected to the valve core 33 via the transmission mechanism 312, the transmission mechanism 312 can also be omitted, and the output shaft of the motor 311 can be rigidly connected to the valve core 33, thereby driving the valve core 33 to rotate.

[0114] Continue to refer to Figure 4The flow regulating valve 16 may further include two shaft seals 162, a bearing 161, and a connector 163. The bearing 161 is fitted onto the valve core 33, with a portion of the bearing 161 located within the first opening 36, enabling a rotatable connection between the valve core 33 and the valve body assembly 32 at the first opening 36. One shaft seal 162 is fitted onto the valve core 33 and located within the receiving cavity 35, sealing the first opening 36 and the receiving cavity 35 to prevent leakage of the cooling medium from the first opening 36. The other shaft seal 162 is fitted onto the connector 163, sealing the connector 163 and the first opening 36 to improve the sealing effect. The connector 163 is fastened to one end located in the first opening 36, and is used to fasten to the first gear 1321, thus achieving a fastening connection between the valve core 33 and the first gear 3121.

[0115] It should be noted that in some instances, the connector 163 can be removed, the first gear 3121 is fastened to the valve core 33, and both shaft seals 162 are fitted onto the valve core 33.

[0116] Figure 6 yes Figure 4 A partially enlarged view of the connector portion in the embodiment shown, in the disconnected state. Figure 7 yes Figure 4 A partially enlarged view of the connector portion in the illustrated embodiment in a conductive state.

[0117] Continue to refer to Figure 4 and reference Figure 6 The connector 40 may include a hollow connector base 41, a piston 42, and a spring 43. The first end of the connector base 41 is securely connected to the valve body assembly 32, and the interior of the connector base 41 communicates with the second opening 37. The second end of the connector base 41 is used to mate with the male connector 141, enabling communication between the male connector 141 and the connector base 41. An annular abutment portion 411 extends from the interior of the connector base 41, with the interior of the abutment portion 411 being through-hole. The abutment portion 411 is located between the first and second ends of the connector base 41. The spring 43 is located within the connector base 41 and abuts against both the valve body 30 and the piston 42. When the connector 40 and the male connector 141 are not engaged, the spring 43 causes the piston 42 to abut against the abutment portion 411. When the piston 42 abuts against the abutment portion 411, the first end of the piston 42 is located inside the abutment portion 411, and the outer wall of the first end of the piston 42 is sealed to the inner wall of the abutment portion 411, which can prevent the cooling medium from passing through the interior of the abutment portion 411, thereby blocking the cooling medium from passing through the connector base 41. The second end of the piston 42 abuts against one end of the spring 43.

[0118] Understandably, the function of spring 43 is to ensure that piston 42 always experiences a spring force, which causes piston 42 to always move in the direction towards the abutment portion 411, thereby enabling piston 42 to abut against the abutment portion 411. To achieve the cooperation between piston 42 and spring 43, please refer to... Figure 6 The end face of the piston 42 near the valve body assembly 32 may be provided with an abutment groove 421 into which one end of the spring 43 is inserted.

[0119] Continue to refer to Figure 6 The inner wall between the end face of the second end of the connector base 41 and the outer end face of the abutment portion 411 defines a guide opening 414. The guide opening 414 is used to position the relative positions of the connector base 41 and the male connector 141 when the male connector 141 is inserted into the connector base 41, enabling blind insertion of the flow regulating valve 16 and the male connector 141. The first seal 44 is located within the guide opening 414, ensuring a sealed connection between the connector base 41 and the male connector 141. The outer end face of the abutment portion 411 refers to the end face of the abutment portion 411 away from the valve body portion 30. Furthermore, the plane containing the outer end face of the abutment portion 411 intersects the axis of the piston 42.

[0120] Continue to refer to Figure 6 The inner end face of the abutment portion 411 facing the valve body assembly 32 and the inner wall of the connector base 41 together define a first stepped surface 412. The outer end face of the abutment portion 411 away from the valve body assembly 32 (the end face facing the male connector 141) and the inner wall of the connector base 41 together define a second stepped surface 413. The second stepped surface 413 is used to abut against the male connector 141 inserted into the connector base 41, ensuring that the male connector 141 is connected to the connector base 41 in place. The outer wall of the piston 42 defines a third stepped surface 424. The inner end face of the abutment portion 411 abuts against a portion of the outer wall of the piston 42 within the third stepped surface 424, so that the piston 42 abuts against the abutment portion 411, thereby preventing the piston 42 from passing through the abutment portion 411 and falling out of the connector base 41, and ensuring that the piston 42 is always located within the connector base 41.

[0121] When the piston 42 abuts against the contact portion 411, the interior of the connector base 41 is not open, and the cooling medium cannot flow through the connector base 41 (e.g., Figure 6 As shown), at this time, the connector 40 is in the disconnected state. When the piston 42 and the abutment 411 are no longer in contact, the cooling medium can pass through the mating area between the piston 42 and the abutment 411, thereby allowing the cooling medium to pass through the connector base 41, at which point the connector 40 is in the conductive state. Specifically, when the piston 42 and the abutment 411 are no longer in contact, in order to allow the cooling medium to pass through the connector base 41, continue referring to... Figure 6A through-flow channel 423 can be provided on the piston 42, having an outlet end and at least one inlet end. The outlet end is located on the end face of the piston 42 facing the valve body assembly 32. At least one inlet end is located on the outer wall of the piston 42 and at the center of the piston 42. When there are multiple inlet ends, they are spaced apart around the outer wall of the piston 42. Of course, in some examples, multiple first grooves can also be provided on the outer wall of the second end of the piston 42, with the center line of each first groove extending along the axial direction of the piston 42, i.e., the piston 42 is gear-shaped, and the cooling medium passes through the joint base 41 through the gap between the outer wall of the piston 42 and the inner wall of the joint base 41.

[0122] Continue to refer to Figure 6 The piston 42 abuts against the spring 43 and the abutment portion 411 respectively, with a portion of the piston 42 inserted into the abutment portion 411. This divides the interior of the connector base 41 into a first channel segment 416 and a second channel segment 417 that are isolated from each other, thus preventing the cooling medium from flowing between the first channel segment 416 and the second channel segment 417. At this time, the connector portion 40 is in a disconnected state. Since the piston 42 can slide within the connector base 41 and the spring 43 can be compressed, when the abutment portion 411 and the piston 42 no longer abut against each other, and the portion of the piston 42 inserted into the abutment portion 411 is no longer sealed, the interior of the connector base 41 can be made open, and the cooling medium can pass through the connector base 41. Therefore, the connector portion 40 is configured in a conductive state (e.g., Figure 7 (as shown) and disconnected state (as shown) Figure 6 (As shown), in addition, the male terminal connector 141 can switch the connector 40 from the disconnected state to the connected state.

[0123] Continue to refer to Figure 6 When the connector 40 is in the open state, the piston 42 abuts against the abutment portion 411, and a portion of the piston 42 is inserted into the abutment portion 411, thereby dividing the interior of the connector base 41 into a first channel segment 416 and a second channel segment 417 that are isolated from each other. (Continue to refer to...) Figure 7 When the connector 40 is in the conducting state, there is a gap between the piston 42 and the abutment 411 in the length direction of the connector base 41, so that the interior of the connector base 41 is open and the cooling medium can flow through the interior of the connector base 41.

[0124] The process of switching the connector 40 from the disconnected state to the connected state is as follows: part of the male connector 141 is inserted into the connector base 41 along the axial direction of the connector base 41 and abuts against the piston 42. The male connector 141 pushes the piston 42 to move in the direction close to the valve body assembly 32 and compresses the spring 43 until the male connector 141 abuts against the abutting part 411, so that the interior of the connector base 41 is open and the cooling medium in the first pipe 12 can flow into the second opening 37 through the interior of the male connector 141 and the connector base 41.

[0125] The process of switching the connector 40 from the conducting state to the disconnected state is as follows: the male connector 141 is pulled out from the connector base 41. Since the spring 43 is currently in a compressed state, after the male connector 141 is no longer in contact with the piston 42, the spring 43 will drive the piston 42 to move in a direction away from the valve body assembly 32 until the piston 42 is inserted into the abutment part 411 and abuts against the abutment part 411, so as to divide the interior of the connector base 41 into a first channel segment 416 and a second channel segment 417 that are isolated from each other.

[0126] The fit between the connector 40 and the male connector 141 can, on the one hand, enable the flow regulating valve 16 to connect with the first pipe 12, and on the other hand, improve the connection speed between the first pipe 12 and the flow regulating valve 16.

[0127] It should be noted that the male connector 141 in the application embodiment is the male connector 141 of the quick connector 14 in the prior art. Therefore, the specific structure of the male connector 141 is not specifically limited here. For example, refer to... Figure 7 The male connector 141 may include a hollow stepped shaft portion. The outer wall of the stepped shaft portion defines a stepped surface that abuts against the abutment portion 411. One end of the stepped shaft portion communicates with the first conduit 12, and the other end of the stepped shaft portion is used to abut against the piston 42. The end face of the piston 42 is provided with a groove that connects the interior of the connector base 41 and the interior of the stepped shaft portion, allowing cooling medium to enter the interior of the connector base 41 from the male connector.

[0128] It should also be noted that the male connector 141 and the connector base 41 can be detachably connected by snap-fit, abutment or other means, without any specific restrictions.

[0129] Continue to refer to Figure 6 In some embodiments, the connector 40 may further include a first seal 44 disposed inside the second end of the connector base 41. The first seal 44 is used to sleeve on the male connector 141 and abut against the inner walls of the male connector 141 and the connector base 41 respectively when the male connector 141 is inserted into the connector base 41 and abuts against the abutting part 411, so as to improve the sealing effect between the male connector 141 and the connector base 41 and prevent the cooling medium from leaking.

[0130] Continue to refer to Figure 6 In some embodiments, the connector 40 may further include a second seal 45, which is fitted onto the piston 42 and abuts against the inner wall of the abutment portion 411 and the outer wall of the piston 42 respectively. The second seal 45 can improve the sealing effect between the abutment portion 411 and the piston 42, so that the spaces on both sides of the piston 42 are not connected.

[0131] Continue to refer to Figure 6 To prevent the second seal 45 from falling off during the movement of the piston 42, a third annular groove 422 can be provided on the outer wall of the end of the piston 42 that mates with the abutment part 411, and part of the second seal 45 is inserted into the third annular groove 422.

[0132] Continue to refer to Figure 6 In some embodiments, the connector 40 may also include a third seal 46, which is fitted onto the first end of the connector base 41 and abuts against the inner wall of the second opening 37 and the connector base 41 respectively, thereby improving the sealing effect of the connector base 41 and the valve body assembly 32 and preventing leakage of cooling medium.

[0133] Figure 8 This is a cross-sectional view of another flow regulating valve provided in the embodiments of this application. Figure 8 The flow regulating valve 16 in the middle and Figure 4 The difference between the flow regulating valve 16 and the connector base 41 lies in their structure. Figure 8 The connector base 41 does not have a guide port 414, and the outer end face of the abutment part 411 is aligned with the end face of the second end of the connector base 41. In addition, a snap-fit ​​part 418 extends from the outer wall of the connector base 41. The snap-fit ​​part 418 is used to snap into the mating part provided on the male connector 141, so that the connector base 41 and the male connector 141 can be snapped together, thereby allowing the flow regulating valve 16 to automatically connect with the male connector 141.

[0134] The structure of the snap-fit ​​part 418 is not specifically limited here. For example, the snap-fit ​​part 418 can be an annular protrusion provided around the connector base 41, or the snap-fit ​​part 418 includes at least two snap-fit ​​protrusions, which are evenly arranged along the circumferential direction of the connector base 41.

[0135] In the above description, the flow regulating valve 16 is located on the liquid inlet 171 side of the cold plate 17, and the shut-off valve 15 is located on the liquid outlet 172 side of the cold plate 17. However, the shut-off valve 15 can also be replaced by the flow regulating valve 16. Figure 9 This is a schematic diagram of another server 100 provided in an embodiment of this application. For example... Figure 9 As shown, Figure 9and Figure 3A The difference is that the outlet 172 of the cold plate 17 is connected to the input end of the flow regulating valve 16, and the output end of the flow regulating valve 16 is connected to the input end of the second pipe 13.

[0136] The output end of the flow regulating valve 16 between the second pipe 13 and the outlet 172 of the cold plate 17 is also connected to the input end of the second pipe 13 via a male connector 141. Furthermore, the structure of the flow regulating valve 16 has been described in detail above and will not be repeated here.

[0137] In the above description, the rotation of the valve core 33 is achieved by the motor 311, thus the opening degree of the valve body 30 can be remotely controlled. However, the rotation of the valve core 33 can also be manually controlled by an operator.

[0138] Figure 10 This is a cross-sectional view of a manual component provided in an embodiment of this application.

[0139] In some possible implementations, embodiments of this application also provide a flow regulating valve 16, which is connected to... Figure 4 and Figure 8 The difference in the flow control valve 16 shown is that the drive assembly 31 is replaced with... Figure 10 Manual component 50. (See reference) Figure 10 The manual assembly 50 may include a mounting base 51 and a locking member 52.
