[0002] Internet service providers, enterprise platforms, research institutions, etc. all have a lot of computing needs. The operating platform that carries storage, computing, and network needs is called a data center. The information and communication technology (ICT) equipment in the data center can include multiple servers. The server generates heat when running, so the server needs to be equipped with a liquid cooling system to ensure the normal operation of the server and the ICT equipment in the data center.

[0003] In order to ensure that the server can work within a reasonable temperature range, the server usually uses liquid cooling to dissipate heat. The server's liquid cooling system may include a cold plate, a mainfold, and a liquid cooling pipe used to connect the two. The liquid cooling joint can realize the connection between the liquid cooling pipes, and can also realize the connection between the liquid cooling pipe and the cold plate and mainfold. The liquid cooling joint can realize the circulation of coolant to quickly remove the heat generated during the operation of the server.

[0004] In the related art, one end of the liquid cooling joint can be used to connect a liquid cooling pipe, and the other end can be used to connect another liquid cooling pipe, so that the coolant can flow in the liquid cooling system. The liquid cooling joint is fixedly connected to the liquid cooling pipe. During the subsequent maintenance of the liquid cooling system, the staff needs to disassemble the liquid cooling joint, liquid cooling pipe and liquid cooling plate as a whole, which is difficult to operate and has low maintenance efficiency. Utility Model Content

[0005] The embodiments of the present application provide a liquid cooling joint, a server and a computing device, which can solve the problem of difficult maintenance of the liquid cooling joint.

[0006] In a first aspect, an embodiment of the present application provides a liquid cooling joint, comprising a first joint, a second joint and a locking assembly. The first joint is provided with a first axial channel. The second joint is provided with a second axial channel. The second joint is docked with the first joint so that the first axial channel is connected to the second axial channel. The locking assembly is used to detachably connect the first joint and the second joint. The locking assembly includes a locking hook, one end of which is provided on the second joint, and the other end of which can be hooked or detached from the first joint, so that the first joint and the second joint are in a connected state or a separable state.

[0007] The liquid cooling joint provided in the embodiment of the present application, the first joint and the second joint can be locked or unlocked by a locking assembly. Therefore, during the maintenance of the liquid cooling system, the staff can disassemble the first joint and the second joint to maintain the local area of ​​the liquid cooling system. The staff does not need to disassemble the liquid cooling plate and other structures, which is conducive to reducing the maintenance difficulty of the staff and improving the maintenance efficiency.

[0008] In a possible implementation, the lock hook includes a connecting portion and a locking portion. The connecting portion is rotatably connected to the second joint. The first joint may be provided with a locking portion, and when the locking assembly is in a hooking state, the locking portion hooks the locking portion.

[0009] In the embodiment of the present application, when the first joint and the second joint are connected, the locking hook can hook the locking portion of the first joint through the locking portion to fix the first joint and the second joint in connection.

[0010] In a possible implementation, the first joint includes a first tube body. The first axial channel is disposed through the first tube body, and the clamping portion is disposed outside the first tube body. The connecting portion and the locking portion may form a hooking space, and when the locking assembly is in a hooking state, the clamping portion is located in the hooking space.

[0011] In the embodiment of the present application, the connecting portion and the locking portion can form a hooking space toward the locking portion. During the rotation of the locking portion toward the first joint, when the locking portion rotates to make the locking portion located in the hooking space, the locking portion can block the first joint from moving away from the second joint, so as to achieve a fixed connection between the first joint and the second joint.

[0012] In a possible implementation, the second joint includes a second tube body and a mounting portion. The second axial passage is provided through the second tube body, and the mounting portion can be provided outside the second tube body. The connecting portion is rotatably connected to the mounting portion, and along the axial direction of the first axial passage, the mounting portion is butted against the engaging portion and is sealed and connected.

[0013] In the embodiment of the present application, the mounting portion of the second joint can be used to fix the connecting portion so that the connecting portion can be rotatably connected to the second joint. The surface of the clamping portion facing the mounting portion can be used to be sealed and connected to the mounting portion of the second joint. When the locking portion is rotated to hook the clamping portion of the first joint, the locking portion can make the mounting portion and the clamping portion fit tightly together to reduce the mounting gap between the mounting portion and the clamping portion, thereby reducing the possibility of leakage caused by the coolant leaking through the mounting gap between the first joint and the second joint.

[0014] In a possible implementation, along the axial direction of the first axial channel, the locking portion has an abutting surface facing away from the mounting portion, and when the locking assembly is in a hooked state, the locking portion abuts against the abutting surface.

[0015] In the embodiment of the present application, when the locking portion abuts against the abutment surface of the snap-fit ​​portion, the locking portion can apply a force toward the mounting portion to the snap-fit ​​portion so that the snap-fit ​​portion and the mounting portion can remain in a connected state, thereby reducing the possibility of the snap-fit ​​portion moving away from the mounting portion, causing the first joint and the second joint to separate, which is beneficial to improving the connection reliability of the first joint and the second joint.

[0016] In a possible implementation manner, the abutting surface and the outer wall of the first tube body have a first inclination angle, and the first inclination angle is an acute angle.

[0017] In the embodiment of the present application, by setting the first inclination angle formed between the abutting surface and the first tube body to be an acute angle, a guiding effect can be provided for the locking portion to rotate to hook with the clamping portion. When the locking portion contacts the abutting surface of the clamping portion, the inclined abutting surface can guide the locking portion to continue rotating until the locking portion and the clamping portion are locked. It is easy to understand that in this process, the contact area between the locking portion and the abutting surface gradually increases, so that the first joint and the second joint can be firmly connected.

[0018] In a possible implementation, the locking hook further includes an operating portion, one end of the locking portion is connected to the connecting portion, the other end of the locking portion is connected to the operating portion, and a second inclination angle is formed between the operating portion and the outer wall of the first tube body.

The operating portion can provide a force application point for the staff. The staff can hold the operating portion of the lock hook to apply a rotational force to the lock hook, so that the locking portion can be hooked or disengaged from the clamping portion.

[0020] In a possible implementation, when the locking assembly is in the hook state, part of the first tube body is located in the second axial channel of the second joint, or part of the second tube body is located in the first axial channel of the first joint.

[0021] In the embodiment of the present application, the second tube body can be inserted into the first axial channel. The portion of the second tube body located in the first axial channel can be an insertion portion. The insertion portion can cooperate with the inner wall of the first axial channel to limit the radial position of the first tube body and the second tube body, and the first joint and the second joint are not easily offset in the radial direction, which is conducive to improving the connection stability of the first joint and the second joint.

[0022] In a possible implementation, when the locking assembly is in the hook state, part of the first tube body is located in the second axial channel of the second joint, and part of the second tube body is located in the first axial channel of the first joint.

[0023] In a possible implementation, along the radial direction of the first tube body, a first sealing ring is provided between the first tube body and the second tube body, and the first sealing ring seals a radial gap between the first joint and the second joint.

[0024] In the embodiment of the present application, a first sealing ring is provided between the outer wall of the insert part and the inner wall of the first axial channel, so as to seal the radial gap between the insert part and the first axial channel, thereby preventing the coolant in the first axial channel and the second axial channel from leaking through the radial gap.

[0025] In a possible implementation manner, a second sealing ring is provided between the mounting portion and the engaging portion along the axial direction of the first axial channel.

[0026] In the embodiment of the present application, the clamping portion and the mounting portion can compress the second sealing ring therebetween, so that the coolant in the first axial channel and the second axial channel is not easily leaked through the gap between the clamping portion and the mounting portion.

[0027] In a possible implementation, the locking assembly further includes a fixing rod, which is disposed on the outer wall surface of the mounting portion of the second joint, and the locking hook is rotatably connected to the fixing rod.

[0048] The server provided in the embodiment of the present application can be applied to a data center. Internet service providers, enterprise platforms, research institutions, etc. all need a lot of computing needs, and the operating platform that carries storage, computing, and network needs is called a data center. The data center may include a computer room. At least one computing device is provided in the computer room. The computing device may be a communication cabinet, a power cabinet, etc. The computing device may include a server. The number of servers may be multiple. For example, the computing device may include 10-50 servers. Among them, the server in the embodiment of the present application may be a whole cabinet server, a rack server, and other servers, which are not limited in this application.

[0049] The computer room is also provided with a refrigeration system. The refrigeration system can dissipate heat from the internal environment of the computer room to keep the computing equipment running normally. In the embodiment of the present application, the specific structure and working principle of the refrigeration system in the computer room are not described in detail.

[0050] With the rapid development of AI technology, high-performance servers are widely used. When the server is working, part of the electrical energy will be converted into heat energy, which will increase the temperature inside the server. When the temperature is too high, it is easy to affect the normal operation of the server or even cause failure. In order to ensure that the server works in a reasonable temperature range, the server usually uses liquid cooling to dissipate heat.

[0051] The liquid cooling system of the server may include a cold plate, a mainfold, and a liquid cooling pipe for connecting the two. The liquid cooling joint may realize the connection between the liquid cooling pipes, and may also realize the connection between the liquid cooling pipe and the cold plate and the mainfold. The liquid cooling joint may realize the circulation of the cooling liquid to quickly remove the heat generated during the operation of the server.

[0052] In the related art, one end of the liquid cooling joint can be used to connect a liquid cooling pipe, and the other end can be used to connect another liquid cooling pipe, so that the coolant can flow in the liquid cooling system. The liquid cooling joint is fixedly connected to the liquid cooling pipe. During the subsequent maintenance of the liquid cooling system, the staff needs to disassemble the liquid cooling joint, liquid cooling pipe and liquid cooling plate as a whole, which is difficult to operate and has low maintenance efficiency.

[0053] Based on the above technical problems, the applicant has improved the structure of the existing liquid-cooled joint. In an embodiment of the present application, the liquid-cooled joint includes a detachable first joint and a second joint. The first joint and the second joint can be connected to form a whole or separated into two parts through a locking assembly. Specifically, one end of the locking hook of the locking assembly is arranged on the second joint, and when the other end of the locking hook is hooked to the first joint, the first joint and the second joint can be fixedly connected. The coolant can flow through the first axial channel of the first joint and the second axial channel 120a of the second joint and perform liquid cooling heat exchange. When the locking hook is detached from the first joint, the first joint can be detached from the second joint to achieve the detachability of the first joint and the second joint.

[0054] Therefore, during the maintenance of the liquid cooling system, the staff can remove the first joint and the second joint to maintain the local area of ​​the liquid cooling system, which can reduce the possibility of disassembling the entire liquid cooling system, resulting in greater difficulty in maintenance and affecting maintenance efficiency.

[0055] The liquid cooling joint, server and computing device provided in the embodiments of the present application are described in detail below through specific implementation methods.

[0056] Figure 1 1 is a three-dimensional structural diagram of an application state of a liquid cooling joint 100 provided in an embodiment of the present application. At this time, the first joint 110 and the second joint 120 can be locked together by the locking hook 131 of the locking assembly 130. The first joint 110 and the second joint 120 are in a connected state. Figure 2 1 is a schematic diagram of a three-dimensional structure of a liquid cooling joint 100 provided in an embodiment of the present application in a disassembled state. At this time, the locking hook 131 of the locking assembly 130 unlocks the first joint 110. The first joint 110 and the second joint 120 are in a disassembled and separable state. Figure 3 It is a schematic diagram of the main structure of a liquid cooling joint 100 provided in an embodiment of the present application.

[0057] Figure 4 It is a schematic cross-sectional structure diagram of a liquid cooling joint 100 provided in an embodiment of the present application. Figure 5 It is a schematic cross-sectional structural diagram of another liquid cooling joint 100 provided in an embodiment of the present application. Figure 6 It is a schematic diagram of the three-dimensional structure of a liquid cooling joint 100 provided in an embodiment of the present application from another perspective.

[0058] This embodiment provides a liquid cooling joint 100, see Figures 1 to 4 As shown, the liquid cooling joint 100 may include a first joint 110 , a second joint 120 and a locking assembly 130 .

[0059] The first joint 110 may be provided with a first axial passage 110a. The first axial passage 110a penetrates the first joint 110 along the axial direction of the first joint 110. The second joint 120 may be provided with a second axial passage 120a. The second axial passage 120a penetrates the second joint 120 along the axial direction of the second joint 120. The second joint 120 and the first joint 110 may be butted together so that the first axial passage 110a is communicated with the second axial passage 120a.

[0060] The locking assembly 130 can be used to detachably connect the first connector 110 and the second connector 120. The locking assembly 130 includes a locking hook 131. One end of the locking hook 131 can be set on the second connector 120, and the other end of the locking hook 131 can be hooked or detached from the first connector 110, so that the first connector 110 and the second connector 120 are in a connected state or a separable state.

[0061] In the embodiment of the present application, the first joint 110 and the second joint 120 can be docked. The ends of the first joint 110 and the second joint 120 that are away from each other can be connected to two liquid cooling tubes respectively. One end of the locking hook 131 is provided on the second joint 120, and the other end of the locking hook 131 can be used to hook the first joint 110. Therefore, when the locking hook 131 hooks the first joint 110, the first joint 110 and the second joint 120 can be fixedly connected. At this time, the coolant in the two liquid cooling tubes can be connected through the first axial channel 110a of the first joint 110 and the second axial channel 120a of the second joint 120, thereby realizing the flow heat exchange of the coolant.

[0062] During the maintenance of the liquid cooling system, the staff can maintain the local area of ​​the liquid cooling system by disassembling the first joint 110 and the second joint 120. The staff does not need to disassemble the liquid cooling plate and other structures, which is conducive to reducing the maintenance difficulty of the staff and improving the maintenance efficiency.

[0063] In some examples, the liquid cooling pipe in the liquid cooling system can be split into multiple sections of liquid cooling pipes with smaller lengths. Two adjacent liquid cooling pipes can be connected through a liquid cooling joint 100. For example, the liquid cooling pipe may include a first liquid cooling pipe, a second liquid cooling pipe, a third liquid cooling pipe or more with multiple sections of smaller lengths. A liquid cooling joint 100 can be used to connect the first liquid cooling pipe and the second liquid cooling pipe, and another liquid cooling joint 100 can be used to connect the second liquid cooling pipe and the third liquid cooling pipe. By analogy, the liquid cooling pipe in the liquid cooling system can be formed by connecting multiple sections of liquid cooling pipes through multiple liquid cooling joints 100, thereby reducing the possibility of interference with other components due to the long length of the liquid cooling pipe on the one hand, and on the other hand, it can also facilitate maintenance by staff.

[0064] Specifically, when the second liquid cooling tube leaks, the staff can separate the first joint 110 and the second joint 120 of the liquid cooling joint 100 on both sides of the second liquid cooling tube to disassemble the second liquid cooling tube for maintenance or replacement, without having to disassemble and maintain the entire liquid cooling tube and liquid cooling plate, which is conducive to improving the convenience of maintenance.

[0065] In some examples, the liquid cooling joint 100 of the embodiment of the present application may be a pagoda head. Specifically, the area of ​​the first joint 110 of the liquid cooling joint 100 used to connect to the liquid cooling pipe may be provided with a plurality of raised structures. The raised structures may be used to improve the connection reliability between the first joint 110 and the liquid cooling pipe. The area of ​​the second joint 120 of the liquid cooling joint 100 used to connect to the liquid cooling pipe may also be provided with a plurality of raised structures. The raised structures may be used to improve the connection reliability between the second joint 120 and the liquid cooling pipe.

[0066] In some possible implementations, see Figure 2 and Figure 3 As shown, the locking hook 131 of the embodiment of the present application may include a connecting portion 1311 and a locking portion 1312. The connecting portion 1311 is rotatably connected to the second joint 120. The first joint 110 may be provided with a locking portion 111. When the locking assembly 130 is in a hooking state, the locking portion 1312 may hook the locking portion 111.

[0067] In the embodiment of the present application, when the first connector 110 and the second connector 120 are connected, the locking hook 131 can hook the locking portion 111 of the first connector 110 through the locking portion 1312 to fix the first connector 110 and the second connector 120 in connection.

[0068] Specifically, one end of the connecting portion 1311 can be rotatably connected to the second joint 120, so the locking portion 1312 on the connecting portion 1311 can rotate around the connection between the connecting portion 1311 and the second joint 120. When the locking portion 1312 rotates to the hook-and-engagement portion 111, the first joint 110 and the second joint 120 can be fixedly connected. When the locking portion 1312 rotates to be disengaged from the engagement portion 111, the first joint 110 and the second joint 120 can be disassembled. Therefore, the staff can operate the matching state of the locking portion 1312 of the lock hook 131 and the engagement portion 111 of the first joint 110 to achieve the connection or disassembly of the first joint 110 and the second joint 120.

[0069] In some possible implementations, see Figure 3 and Figure 4As shown, the first joint 110 of the embodiment of the present application may include a first tube body 112. The first axial channel 110a may be provided through the first tube body 112. The axial direction X of the first axial channel 110a and the axial direction of the first tube body 112 may be in the same direction. The engaging portion 111 may be provided outside the first tube body 112. The connecting portion 1311 and the locking portion 1312 may form a hooking space 131a. When the locking assembly 130 is in the hooking state, the engaging portion 111 may be located in the hooking space 131a.

[0070] In the embodiment of the present application, the connecting portion 1311 and the locking portion 1312 can form a hooking space 131a facing the locking portion 111. When the locking portion 1312 rotates toward the first joint 110, when the locking portion 1312 rotates to make the locking portion 111 located in the hooking space 131a, the locking portion 1312 can block the first joint 110 from moving away from the second joint 120, so as to achieve a fixed connection between the first joint 110 and the second joint 120.

[0071] In some possible implementations, see Figure 4 As shown, the second joint 120 of the embodiment of the present application may include a second tube body 121 and a mounting portion 122. The second axial channel 120a may be provided through the second tube body 121, and the mounting portion 122 may be provided outside the second tube body 121. The connecting portion 1311 may be rotatably connected to the mounting portion 122. The axial direction of the second axial channel 120a and the second tube body and the axial direction X of the first axial channel 110a may be in the same direction. Along the axial direction X of the first axial channel 110a, the mounting portion 122 and the engaging portion 111 may be butted and sealedly connected.

[0072] In the embodiment of the present application, the mounting portion 122 of the second joint 120 can be used to fix the connecting portion 1311, so that the connecting portion 1311 can be rotatably connected to the second joint 120. The surface of the clamping portion 111 facing the mounting portion 122 can be used to be sealed and connected with the mounting portion 122 of the second joint 120. When the locking portion 1312 is rotated to hook the clamping portion 111 of the first joint 110, the locking portion 1312 can make the mounting portion 122 fit tightly with the clamping portion 111, so as to reduce the mounting gap between the mounting portion 122 and the clamping portion 111, and reduce the possibility of leakage caused by the coolant leaking through the mounting gap between the first joint 110 and the second joint 120.

[0073] In some examples, the surfaces of the engaging portion 111 and the mounting portion 122 facing each other may be sealed and connected to more effectively reduce the possibility of cooling liquid leaking through the gap between the engaging portion 111 and the mounting portion 122 .

[0074] In some possible implementations, see Figure 4As shown, along the axial direction X of the first axial channel 110a, the engaging portion 111 may have an abutting surface 111a facing away from the mounting portion 122. When the locking assembly 130 is in the hook state, the locking portion 1312 may abut against the abutting surface 111a.

[0075] In the embodiment of the present application, when the locking portion 1312 abuts against the abutting surface 111a of the engaging portion 111, the locking portion 1312 can apply a force to the engaging portion 111 toward the mounting portion 122 so that the engaging portion 111 and the mounting portion 122 can remain in a connected state, thereby reducing the possibility of the engaging portion 111 moving away from the mounting portion 122, resulting in separation of the first connector 110 and the second connector 120, which is beneficial to improving the connection reliability of the first connector 110 and the second connector 120.

[0076] In some examples, when the locking portion 1312 abuts against the abutting surface 111a of the engaging portion 111, there may be an interference fit between the locking portion 1312 and the engaging portion 111. The locking portion 1312 may generate a certain elastic deformation.

[0077] In some possible implementations, see Figure 4 As shown, the abutting surface 111 a and the outer wall of the first tube body 112 of the embodiment of the present application may have a first inclination angle M. The first inclination angle M may be an acute angle.

[0078] In the embodiment of the present application, by setting the first inclination angle M formed between the abutting surface 111a and the first tube body 112 to be an acute angle, a guiding effect can be provided for the locking portion 1312 to rotate to hook with the engaging portion 111. When the locking portion 1312 contacts the abutting surface 111a of the engaging portion 111, the inclined abutting surface 111a can guide the locking portion 1312 to continue rotating until the locking portion 1312 is locked with the engaging portion 111. It is easy to understand that in this process, the contact area between the locking portion 1312 and the abutting surface 111a gradually increases, so that the first joint 110 and the second joint 120 can be firmly connected.

[0079] In addition, by setting the first inclination angle M formed between the abutting surface 111a and the first tube body 112 to be an acute angle, the locking portion 1312 is not easily disengaged and separated from the locking portion 111 when the locking portion 1312 is hooked with the locking portion 111. The staff needs to apply a certain force to the locking portion 1312 to separate the locking portion 1312 from the locking portion 111, so as to disassemble the first connector 110 and the second connector 120.

[0080] In some examples, the driving force for the locking portion 1312 to rotate can be manually provided by a staff member. In other words, the staff member can apply a force to the locking portion 1312 toward or away from the engaging portion 111 to lock the locking portion 1312 with the engaging portion 111 or disengage from each other, thereby achieving the locking and disassembly of the first connector 110 and the second connector 120.

[0081] In summary, during the process of installing the liquid cooling joint 100, the staff can achieve tool-free installation of the liquid cooling joint 100 in the server. Specifically, since the first joint 110 and the second joint 120 can be detachably connected through the locking assembly 130, the first joint 110 and the liquid cooling pipe can be pre-installed outside the server, and the second joint 120 and the liquid cooling pipe can also be pre-installed outside the server. Then the two liquid cooling pipes are connected in the server through the first joint 110 and the second joint 120. When the first joint 110 and the second joint 120 are respectively connected to the liquid cooling pipe and installed on the server, the first joint 110 and the second joint 120 can be manually locked. Therefore, the staff no longer needs to use operating tools such as calipers to achieve a stable connection between the first joint 110 and the second joint 120, which is conducive to achieving the convenience of connection between the first joint 110 and the second joint 120.

[0082] In addition, a space is reserved in the server for the staff to manually operate the lock hook 131, that is, the first joint 110 and the second joint 120 can be fixedly connected, and there is no need to reserve an operating space in the server for operating tools during the installation of the first joint 110 and the second joint 120, thereby saving the internal space of the server to improve the space utilization rate in the server. It is easy to understand that more structural parts and components can be arranged through the saved space to improve the working performance of the server.

[0083] In some examples, the installation method of the first joint 110 and the liquid cooling pipe can be the same as the connection method of the second joint 120 and the liquid cooling pipe. Taking the first joint 110 and the liquid cooling pipe as an example, the first joint 110 and the liquid cooling pipe can be fixedly connected by a clamp. During the installation process, the caliper clamp can apply a locking force to the clamp to lock the first joint 110 and the liquid cooling pipe. When the first joint 110 and the liquid cooling pipe can be pre-installed outside the server, since it is not limited by the size of the internal space of the server, it is easier to control the consistency of the clamp locking force between the first joint 110 and the liquid cooling pipe of each liquid cooling joint 100, which is conducive to improving the possibility of connection between the liquid cooling joint 100 and the liquid cooling pipes on both sides, and reducing the possibility that the liquid cooling joint 100 is limited by the size of the space when it is installed inside the server, resulting in different locking forces between the liquid cooling joint 100 and the liquid cooling pipe, which leads to the possibility of leakage in some areas.

[0084] In some possible implementations, see Figure 4 As shown, the locking hook 131 of the embodiment of the present application may further include an operating portion 1313. One end of the locking portion 1312 may be connected to the connecting portion 1311, and the other end of the locking portion 1312 may be connected to the operating portion 1313. A second inclination angle N may be formed between the operating portion 1313 and the outer wall of the first tube body 112.

[0085] In the embodiment of the present application, the operating portion 1313 can provide a force application point for the staff. The staff can hold the operating portion 1313 of the lock hook 131 to apply a rotational force to the lock hook 131 so that the locking portion 1312 can be hooked or disengaged from the locking portion 111.

[0086] Specifically, when the staff applies a pressing force toward the engaging portion 111 to the locking portion 1312, the locking portion 1312 can be locked with the engaging portion 111, thereby achieving a fixed connection between the first connector 110 and the second connector 120. When the first connector 110 and the second connector 120 are disassembled, by setting a second inclination angle N between the operating portion 1313 and the second tube body 121, the staff can put their fingers into the space of the second inclination angle N, so as to facilitate the application of a force away from the engaging portion 111 to the locking portion 1312 through the operating portion 1313, so that the locking hook 131 unlocks the first connector 110, thereby achieving the disassembly of the first connector 110 and the second connector 120.

[0087] In some examples, the second inclination angle N may range from 20 degrees to 40 degrees.

[0088] In some possible implementations, see Figure 3 As shown, when the locking assembly 130 is in the hook state, a portion of the first tube 112 can be located in the second axial channel 120 a of the second connector 120 .

[0089] In other examples, a portion of the second tube 121 may be located in the first axial channel 110 a of the first joint 110 .

[0090] In which, taking the example that part of the second tube body 121 can be located in the first axial channel 110a of the first joint 110, the second tube body 121 can be inserted into the first axial channel 110a. The part of the second tube body 121 located in the first axial channel 110a can be the insertion portion 121a. The insertion portion 121a can cooperate with the inner wall of the first axial channel 110a to limit the radial position of the first tube body 112 and the second tube body 121, and the first joint 110 and the second joint 120 are not easy to deviate in the radial direction, which is conducive to improving the connection stability of the first joint 110 and the second joint 120.

[0091] In some possible implementations, see Figure 4As shown, along the radial direction of the first tube body 112, a first sealing ring 140 may be provided between the first tube body 112 and the second tube body 121. The first sealing ring 140 may seal the radial gap between the first joint 110 and the second joint 120.

[0092] In the embodiment of the present application, when the insertion portion 121a of the second tube body 121 is inserted into the first axial channel 110a, a radial gap may be provided between the insertion portion 121a and the first axial channel 110a, so that the insertion portion 121a can be easily installed in the first tube body 112. By providing a first sealing ring 140 between the outer wall of the insertion portion 121a and the inner wall of the first axial channel 110a, the radial gap between the insertion portion 121a and the first axial channel 110a can be sealed to prevent the coolant in the first axial channel 110a and the second axial channel 120a from leaking through the radial gap.

[0093] In some examples, the outer wall of the insert portion 121a may be provided with a first receiving groove 121b. The first sealing ring 140 may be arranged around the bottom wall of the first receiving groove 121b. The first sealing ring 140 may be, but is not limited to, an elastic rubber ring. When the insert portion 121a is inserted into the first axial channel 110a, the first sealing ring 140 may be deformed by being squeezed by the inner wall of the first axial channel 110a and the bottom wall of the first receiving groove 121b. The first sealing ring 140 may be pressed between the first axial channel 110a and the insert portion 121a, thereby sealing the radial gap between the insert portion 121a and the first axial channel 110a.

[0094] In some examples, the number of the first sealing rings 140 may be, but is not limited to, two. When the number of the first sealing rings 140 is plural, the plurality of first sealing rings 140 may be distributed at intervals along the axial direction X of the first axial channel 110 a.

[0095] In some possible implementations, see Figure 4 As shown, along the axial direction X of the first axial channel 110 a , a second sealing ring 150 may be provided between the mounting portion 122 and the engaging portion 111 .

[0096] In the embodiment of the present application, when the first joint 110 and the second joint 120 are butt-jointed, the engaging portion 111 of the first joint 110 and the mounting portion 122 of the second joint 120 can fit each other. The engaging portion 111 and the mounting portion 122 can press the second sealing ring 150 therebetween, so that the coolant in the first axial channel 110a and the second axial channel 120a is not easy to leak through the gap between the engaging portion 111 and the mounting portion 122.

[0097] Specifically, the second sealing ring 150 may be, but is not limited to, an elastic rubber ring. The second sealing ring 150 may seal the axial X gap between the engaging portion 111 and the mounting portion 122 .

[0098] In some examples, along the axial direction X of the first axial channel 110a, at least one of the surfaces of the mounting portion 122 and the engaging portion 111 facing each other may be provided with a second receiving groove 122a. The second sealing ring 150 may be installed in the second receiving groove 122a. The second sealing ring 150 may be deformed by the pressing force of the engaging portion 111 and the bottom wall of the second receiving groove 122a to achieve a sealed connection between the mounting portion 122 and the engaging portion 111, thereby reducing the possibility of leakage of the coolant through the gap between the engaging portion 111 and the mounting portion 122.

[0099] In some possible implementations, see Figure 4 As shown, the locking assembly 130 may further include a fixing rod 132. The fixing rod 132 may be disposed on the outer wall surface of the mounting portion 122 of the second joint 120. The locking hook 131 may be rotatably connected to the fixing rod 132.

[0100] In some examples, one end of the connecting portion 1311 away from the locking portion 1312 can be rotatably connected to the fixing rod 132. The locking hook 131 can be connected to the second joint 120 through the fixing rod 132.

[0101] In some examples, the connecting portion 1311, the locking portion 1312 and the operating portion 1313 may form a locking hook 131 of an integrated structure. The entire locking hook 131 may be in a "U"-shaped structure. Specifically, the locking hook 131 may be formed by a rod body through a bending process. The two ends of the rod body may be wound around the fixed rod 132. Therefore, the connecting portion 1311 may be formed by two sections of the rod body side by side, the locking portion 1312 may be formed by two sections of the rod body side by side, and the operating portion 1313 may be in a "U"-shaped structure. The above-mentioned locking hook 131 structure has a good locking strength and can also be convenient for staff to operate.

[0102] In some examples, the locking assembly 130 of the embodiment of the present application may include at least two sets of locking hooks 131. The two sets of locking hooks 131 may be arranged opposite to each other along the radial direction of the first tube 112, so that the locking force of the first joint 110 and the second joint 120 is evenly distributed, so as to ensure the reliability of the first joint 110 and the second joint 120, and avoid the possibility of leakage caused by the partial non-tightening of the second sealing ring 150.

[0103] In some possible implementations, see Figure 5As shown, the outer wall of the mounting portion 122 may be provided with a mounting groove 122b. The fixing rod 132 may include a mounting section 1321 and an avoidance section 1322. At least part of the mounting section 1321 may be located in the mounting groove 122b. The avoidance section 1322 and the outer wall of the mounting portion 122 may form an avoidance hole. One end of the connecting portion 1311 may be inserted into the avoidance hole to be rotatably connected to the avoidance section 1322.

[0104] In some possible implementations, see Figure 4 As shown, a first barb stopper 113 may be provided on a portion of the outer wall of the first tube body 112 , and a second barb stopper 123 may be provided on a portion of the outer wall of the second tube body 121 .

The first barb stopper 113 may improve the connection stability between the first connector 110 and the liquid cooling tube. The first barb stopper 113 and the liquid cooling tube may be locked by a clamp.

[0106] The outer wall of the second tube body 121 may be provided with a protrusion structure. The protrusion structure may be a second barb stopper 123. The second barb stopper 123 may improve the connection stability between the second connector 120 and the liquid cooling tube. The second barb stopper 123 and the liquid cooling tube may be locked by a clamp.

[0107] For some examples, see Figure 6 As shown, on the side of the second joint 120 away from the first joint 110, when the surface of the outer wall of the second tube body 121 is smooth, one end of the second joint 120 can be fixedly connected to the mainfold by welding, and the other end of the second joint 120 can be detachably connected to the first joint 110. On the side of the first joint 110 away from the first joint 110, the outer wall of the first tube body 112 can be provided with a first barb stopper 113 for connecting to the liquid cooling pipe.

[0108] Alternatively, when the outer wall surface of the first tube body 112 on the side of the first joint 110 away from the second joint 120 is smooth, one end of the first joint 110 can be fixedly connected to the mainfold by welding, and the other end of the first joint 110 can be detachably connected to the second joint 120. In this case, on the side of the second joint 120 away from the first tube body 112, the outer wall of the second tube body 121 can be provided with a second barb stopper 123 for connecting with the liquid cooling tube through a clamp.

[0109] In some examples, the first barb stopper 113 may be an annular structure and disposed around the outer wall of the first tube body 112. The cross-sectional area of ​​the first barb stopper 113 decreases along the axial direction X of the first axial channel 110a and away from the second tube body 121. The cross section is perpendicular to the axial direction X of the first axial channel 110a.

[0110] In some examples, there may be a plurality of first barb stoppers 113. The plurality of first barb stoppers 113 may be distributed along the axial direction (X) of the first tube body 112. For example, the plurality of first barb stoppers 113 may form a pagoda-shaped structure on the first tube body 112.

[0111] In some examples, the structure of the second barb stopper 123 may be the same as that of the first barb stopper 113. Specifically, the second barb stopper 123 may be an annular structure and disposed around the outer wall of the second tube body 121. The cross-sectional area of ​​the second barb stopper 123 decreases along the axial direction (X) of the second axial channel 120a and away from the first tube body 112.

The server may include a motherboard and core components. As the integration of computing devices increases, the power consumption of the core components in the server is getting higher and higher, and the heat generated during operation is also increasing. For example, a device with high power consumption may be a CPU. Therefore, a liquid cooling plate of the cooling system can be set on the CPU.
