Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector and a cooling system. Background Art

[0002] As the performance of servers and data centers continues to improve, efficient heat dissipation and cooling systems have become the key to ensuring the stable operation of equipment. In the cooling system, connectors are key interfaces for fluid pathways such as pipes and cold plates, and their performance directly affects the heat dissipation effect and operational stability of the system.

[0003] The connector usually consists of a male connector, a female connector and a locking piece, and the locking piece is used to lock the male connector and the female connector after connection. However, in the related art, the locking piece is limited by its own shape and structure, and has poor locking ability. When the connector is used in a high-pressure fluid, the force point of the locking piece will be quickly worn and crushed under the action of the high-pressure fluid, which will lead to locking failure, thereby affecting the heat dissipation capacity and reliability of the cooling system.

[0072] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0073] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0074] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0075] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0076] The present application proposes a cooling system, which may be a vehicle cooling system, a server cooling system, or a processing line cooling system, and the present application does not impose any restrictions on this.

[0077] Taking the server cooling system as an example, the cooling system includes a liquid cooling pump, liquid cooling pipes, a radiator, and a connector. The liquid cooling pipe is connected between the radiator and the various heat sources of the server (such as the CPU, GPU). A cooling medium flows in the liquid cooling pipe. The liquid cooling pipe is used to transport the cooling medium cooled by the radiator to the various heat sources of the server, and transport the heated cooling medium back to the radiator for heat dissipation and cooling. The radiator is used to dissipate heat and cool the cooling medium in the cooling system. The liquid cooling pump is used to provide power for the flow of cooling medium between the various heat sources and the radiator of the server.

[0078] The liquid cooling pipeline is usually composed of multiple liquid cooling pipes, and the liquid cooling pipes are connected by connectors. To facilitate the description of the structure of the connector, the liquid cooling pipes connected by the connector are now referred to as the first liquid cooling pipe and the second liquid cooling pipe.

[0079] Please refer to Figure 1 and Figure 2 The connector 1000 includes a first plug 1 and a second plug 2. The first plug 1 is used to connect to the first liquid cooling tube. Specifically, the first plug 1 includes a valve body 14 and a valve seat 15. The valve body 14 has a plug-in port 113. The plug-in port 113 is used to insert the second plug 2. The inner wall surface of the plug-in port 113 is evenly distributed with a plurality of assembly grooves 16. The assembly grooves 16 are used to provide positioning when the first plug 1 is processed to improve the processing accuracy of the first plug 1. The valve seat 15 is provided with a first pipeline interface at one end away from the valve body 14. The first pipeline interface is a threaded interface. The first pipeline interface is used to connect to the first liquid cooling tube. The valve body 14 and the valve seat 15 together form a first flow channel cavity 11. The first flow channel cavity 11 is connected to the first liquid cooling tube.

[0080] The second plug 2 has an insertion end and a connection end that are relatively arranged. The insertion end of the second plug 2 is used to be inserted into the first flow channel cavity 11 through the plug port 113. The connection end of the second plug 2 is provided with a second pipeline interface, which is also a threaded interface. The second pipeline interface is used to connect with the second liquid cooling pipe. The second plug 2 has a second flow channel cavity 23, and the second flow channel cavity 23 is connected to the second liquid cooling pipe. When the second plug 2 is inserted into the first flow channel cavity 11, the first liquid cooling pipe, the first flow channel cavity 11, the second flow channel cavity and the second liquid cooling pipe are connected to each other, and the first liquid cooling pipe and the second liquid cooling pipe are connected. When the second plug 2 is pulled out of the first flow channel cavity 11, the connection between the first flow channel cavity 11 and the second flow channel cavity is disconnected, and the first liquid cooling pipe and the second liquid cooling pipe are disconnected.

[0081] In one embodiment of the present application, the valve seat 15 is connected to the valve body 14 by threads. In this way, when the user needs to maintain or replace the valve seat 15 and the valve body 14, the user only needs to use a tool to gently rotate the valve seat 15 to separate the valve seat 15 from the valve body 14, thereby reducing the difficulty of disassembling the first plug 1 for the user and improving maintenance efficiency.

[0082] The connector 1000 also includes a locking piece 4 and a sleeve 3. The sleeve 3 is movably mounted outside the first plug 1. The sleeve 3 is used to cooperate with the locking piece 4 to lock the second plug 2 after the second plug 2 is inserted into the first flow channel cavity 11, thereby ensuring the stability of the connector 1000 in connecting the first liquid cooling tube and the second liquid cooling tube.

[0083] Specifically, please refer to Figure 3 In the present application, the outer cavity wall of the first flow channel cavity 11 is provided with a first through groove 111, and the first through groove 111 connects the first flow channel cavity 11 and the gap 33 between the sleeve 3 and the first plug 1. The first through groove 111 is a special-shaped groove, and the opening area of ​​the first through groove 111 near the gap 33 is larger than the opening area of ​​the first through groove 111 near the first flow channel cavity 11. For the convenience of description, the opening of the first through groove 111 near the gap 33 is recorded as the first opening 111a, and the opening of the first through groove 111 near the first flow channel cavity 11 is recorded as the second opening 111b. The locking member 4 is arranged in the first through groove 111, and the cross-sectional size of the first opening 111a is larger than the maximum cross-sectional size of the locking member 4. The locking member 4 can be installed in the first through groove 111 through the first opening 111a, and one end of the locking member 4 can extend out of the first through groove 111 through the first opening 111a and contact the inner wall surface 31 of the sleeve 3. The cross-sectional dimension of the second opening 111 b is smaller than the maximum cross-sectional dimension of the locking member 4 , so as to limit the locking member 4 from falling into the first flow channel cavity 11 .

[0084] Please refer to Figure 4 The sleeve 3 can control the locking and releasing of the locking member 4 through its own movement. Specifically, the inner wall surface 31 of the sleeve 3 includes a first mating segment 311 and a second mating segment 312 connected to each other. The first mating segment 311 and the second mating segment 312 are both rotating curved surfaces, and the diameter of the first mating segment 311 is smaller than the maximum diameter of the second mating segment 312.

[0085] The positions of the first mating section 311 and the second mating section 312 relative to the locking member 4 can change with the movement of the sleeve 3. When the first mating section 311 moves to the first through slot 111, the wall surface of the first mating section 311 contacts the outer peripheral surface of the locking member 4, and the movement of the locking member 4 in the direction of the first opening 111a (hereinafter referred to as the upward direction for ease of explanation) is restricted. When the second mating section 312 moves to the first through slot 111, the wall surface of the second mating section 312 is spaced from the outer peripheral surface of the locking member 4, and the locking member 4 is released, so that it can move upward under the push of the second plug 2.

[0086] It is understandable that in other possible implementations of the present application, the second mating section 312 may also be an inclined surface or an arc surface with a generatrix inclined, which is opened on the inner wall surface of the sleeve 3 and can drive the sleeve 3 to move under the push of other structures.

[0087] The outer circumferential surface of the sleeve 3 is also provided with a sealing groove 34, and the sealing groove 34 is filled with a sealing ring, which can be a V-shaped sealing ring, a C-shaped sealing ring, or an O-shaped sealing ring, which is not limited in the present application. The sealing ring is used to ensure the sealing effect between the sleeve 3 and the adjacent components and improve the sealing performance of the sleeve 3.

[0088] Please refer to Figure 2 and Figure 3 In order to drive the sleeve 3 to move, the connector 1000 also includes a driving member 5 and a third elastic member 7. The third elastic member 7 is arranged between the outer wall surfaces of the first plug 1 of the sleeve 3 and can be compressed or released with the movement of the sleeve 3.

[0089] The driving member 5 is arranged on the first plug 1. Specifically, the outer cavity wall of the first flow channel cavity 11 is further provided with a second through groove 112. The second through groove 112 is connected to the first flow channel cavity 11 and the gap 33 between the sleeve 3 and the first plug 1. In terms of the setting position, the second through groove 112 is closer to the plug port 113 than the first through groove 111. The opening area of ​​the second through groove 112 near the gap 33 is larger than the opening area of ​​the second through groove 112 near the first flow channel cavity 11. For the convenience of description, the opening of the second through groove 112 near the gap 33 is recorded as the third opening 112a, and the opening of the second through groove 112 near the first flow channel cavity 11 is recorded as the fourth opening 112b. The driving member 5 is disposed in the second through slot 112, and the cross-sectional dimension of the third opening is larger than the maximum cross-sectional dimension of the driving member 5. The driving member 5 can be installed in the second through slot 112 through the third opening 112a, and one end of the driving member 5 can extend out of the second through slot 112 through the third opening 112a and contact the inner wall surface 31 of the sleeve 3. The cross-sectional dimension of the fourth opening is larger than the maximum cross-sectional dimension of the driving member 5 to limit the driving member 5 from falling into the first flow channel cavity 11.

[0090] When the sleeve 3 is in the initial position, the locking member 4 is located in the first mating section 311 of the sleeve 3, and the driving member 5 is located in the second mating section 312 of the sleeve 3. After the second plug 2 is inserted into the first flow channel cavity 11 from the plug interface 113, the driving member 5 can move upward under the push of the second plug 2 and contact the second mating section 312. During the contact process between the driving member 5 and the second mating section 312, the driving member 5 will push against the second mating section 312 and the insertion direction of the second plug 2 of the sleeve 3 (for ease of description, the latter will be used in the following) until the second mating section 312 reaches the first through groove 111 and releases the locking member 4. Subsequently, the locking member 4 will move upward under the push of the second plug 2 and continue to push backward against the sleeve 3.

[0091] During the backward movement of the sleeve 3, the third elastic member will be continuously compressed. When the thrust of the driving member 5 and the locking member 4 on the sleeve 3 is removed, the sleeve 3 will return to its original state under the action of the third elastic member.

[0092] The number of driving members 5 can be set to one, two, or three. In one embodiment of the present application, the number of driving members 5 is set to three, and the three locking members 4 are evenly distributed around the first plug 1. In this way, the stability of the force applied when the second plug 2 is inserted into the plug interface 113 is ensured, thereby improving the smoothness of the insertion of the second plug 2 into the plug interface 113.

[0093] Please refer to Figure 5 and Figure 6 The second plug 2 includes a main body 21 and a boss structure 22 arranged around the main body 21, the boss structure 22 is composed of a platform surface 222, a push surface 221 and a locking surface 223, and the push surface 221 and the locking surface 223 are respectively arranged on both sides of the platform surface 222. The platform surface 222, the push surface 221 and the locking surface 223 can be a rotational curved surface, an inclined surface, or an arc surface with a generatrix inclined, which is not limited in the present application.

[0094] Please refer to Figures 7 to 16 , the connection method of the connector 1000 provided in the present application will be described in detail below in combination with the above-mentioned drawings.

[0095] Please refer to Figure 7 and Figure 8 In the initial state, the boss structure 22 of the second plug 2 has not been inserted into the first flow channel cavity 11, and the sleeve 3 is located at the initial position. In the initial position, the first matching section 311 of the inner wall surface of the sleeve 3 is arranged corresponding to the first through groove 111 to cooperate with the first through groove 111 to limit the movement of the locking member 4. The matching relationship between the locking member 4 and the sleeve 3 is as shown in FIG. Figure 7The second matching section 312 of the sleeve 3 is located at the second through slot 112 and is in contact with or spaced from the driving member 5 in the second through slot 112. The matching relationship between the driving member 5 and the sleeve 3 is as shown in FIG. Figure 8 shown.

[0096] Please refer to Fig. 9 and Fig.10 When the boss structure 22 of the second plug 2 is inserted into the first flow channel cavity 11, the push surface 221 of the second plug 2 will contact the driving member 5 and push the driving member 5 to leave the bottom of the second through groove 112 and move upward. In the process of moving upward, the driving member 5 will contact the second matching section 312 of the sleeve 3 and push the sleeve 3 to move backward, compressing the third elastic member 7. The position of the driving member 5 is shown in FIG. Fig. 9 shown.

[0097] Since the first through slot 111 is located farther from the plug-in port 113 than the second through slot 112, the locking member 4 disposed in the first through slot 111 is still at a certain distance from the abutting surface 221. Fig.10 shown.

[0098] Please refer to Fig.11 and Fig.12 When the second plug 2 is inserted into the first flow channel cavity 11 for a certain distance, the driving member 5 moves to the platform surface 222, and the driving member 5 stops moving upward. At this time, the second matching section 312 of the sleeve 3 moves just above the locking member 4 under the push of the driving member 5. The position of the driving member 5 is shown in FIG. Fig.11 shown.

[0099] At this time, the locking member 4 starts to contact the push surface 221, and can leave the bottom of the first through groove 111 and move upward under the push of the push surface 221. During the upward movement of the locking member 4, it will contact the second matching section 312 of the sleeve 3 and push the sleeve 3 to continue to move backward. Fig.12 shown.

[0100] Please refer to Fig.13 and Fig.14 , the second plug 2 continues to extend into the first flow channel cavity 11, at this time, the driving member 5 reaches the locking surface 223, and the position of the driving member 5 is as follows Fig.13 shown.

[0101] The locking member 4 reaches the platform surface 222, the position of the locking member 4 no longer rises, and the position of the sleeve 3 retreats to the limit. Fig.14 shown.

[0102] Please refer to Fig.15 and Fig.16When the second plug 2 reaches the limit position of the first flow channel cavity 11, the second plug 2 stops moving. At this time, the driving member 5 leaves the boss structure 22 and falls back into the bottom of the second through groove 112. The position of the driving member 5 is shown in FIG. Fig.15 shown.

[0103] The locking member 4 reaches the locking surface 223, the height of the locking member 4 decreases, and it can no longer abut the second matching section 312. After losing the push, the sleeve 3 will recover forward under the action of the third elastic member 7. The first matching section 311 of the sleeve 3 contacts the locking member 4 again and prevents the locking member 4 from moving upward. Fig.16 shown.

[0104] When the second plug 2 is inserted and pulled out, the boss structure 22 on the second plug 2 pushes the locking member 4 upward, and the upward movement of the locking member 4 is blocked by the sleeve 3 , so that the second plug 2 is locked in the first flow channel cavity 11 .

[0105] Similarly, during the locking process of the second plug 2 , the second plug 2 can be released in the first flow channel cavity 11 by manually moving the sleeve 3 backward to remove the obstruction of the sleeve 3 to the upward movement of the locking member 4 .

[0106] Please refer to Figure 4 In one embodiment of the present application, a groove 32 is provided on the outer circumference of the sleeve 3, and the groove is recessed toward one side of the gap. The groove 32 is used to provide a force point for the user to hold the sleeve 3, thereby improving the user's comfort during operation and preventing operational errors or safety hazards caused by hand slipping during operation.

[0107] It can be seen from the locking principle of the connector 1000 that the locking of the first plug 1 to the second plug 2 mainly depends on the cooperation between the sleeve 3 and the locking member 4 .

[0108] However, in the related art, the locking member 4 is usually a spherical structure, which also results in point contact between the locking member 4 and the sleeve 3. The locking member 4 and the sleeve 3 have a small force bearing area. In high-pressure fluid, the force bearing points of the locking member 4 and the sleeve 3 are prone to rapid wear and collapse, resulting in locking failure.

[0109] To solve the above problem, in the present application, the locking member 4 is in line contact with the first matching section 311 of the sleeve 3, so as to increase the force bearing area of ​​the force bearing point of the locking member 4 and improve the compressive strength of the locking member 4.

[0110] Hereinafter, the locking member 4 provided in the present application will be described in detail with reference to the accompanying drawings.

[0111] Please refer to Figures 17 to 19The locking member 4 includes a first end face 41, a second end face 42 and a connecting curved surface 43. The first end face 41 and the second end face 42 are arranged relatively spaced apart. The connecting curved surface 43 is connected between the first end face 41 and the second end face 42. The connecting curved surface 43 may be as follows: Fig.18 The smooth curved surface shown in FIG. Fig.19 The connecting curved surface 43 is used to contact the first mating section 311 of the sleeve 3, so as to transform the point contact between the locking member 4 and the sleeve 3 into a line contact, thereby increasing the force-bearing area of ​​the locking member 4 and the sleeve 3, improving the compressive strength of the locking member 4, and improving the reliability of the connector 1000.

[0112] On the other hand, in order to reduce the friction between the driving member 5 and the second plug 2 and the sleeve 3 during the movement, the driving member 5 is usually manufactured into a spherical structure, and the roller structure setting of the locking member 4 can be distinguished from the driving member 5 in shape, thereby preventing the operator from assembling the driving member 5 and the locking member 4 incorrectly during the assembly of the connector 1000.

[0113] Please refer to Fig.18 In one embodiment of the present application, the distance between the first end face 41 and the second end face 42 is A, and the maximum distance between any two points on the surface of the connecting surface 43 is B, A>B. In this way, the axial length of the locking member 4 is maximized per unit volume, thereby increasing the contact length between the connecting surface 43 and the sleeve 3, increasing the force-bearing area between the locking member 4 and the sleeve 3, improving the compressive strength of the locking member 4, and improving the reliability of the connector 1000.

[0114] Please refer to Fig. 20 In one possible implementation mode of the present application, the generatrix of the connecting surface 43 is set in an arc shape, and the curvature of the arc is set to be the same as the curvature of the first matching section 311 of the inner wall surface 31 of the sleeve 3, so that the connecting surface 43 and the first matching section 311 of the sleeve 3 can be completely fitted, thereby increasing the contact area between the connecting surface 43 and the first matching section 311 of the sleeve 3, increasing the force-bearing area of ​​the locking member 4 and the sleeve 3, improving the compressive strength of the locking member 4, and improving the reliability of the connector 1000.

[0115] It can be understood that in order to lock the second plug 2, the locking member 4 needs to be in contact with the sleeve 3, and the locking member 4 also needs to be in contact with the second plug 2 itself. In order to improve the locking ability of the locking member 4 for the second plug 2 and reduce the stress deformation at the connection between the locking member 4 and the second plug 2, in one embodiment of the present application, the locking member 4 is in line contact with the second plug 2, so as to increase the stress area of ​​the locking member 4 at the second plug 2, improve the compressive strength of the locking member 4, and improve the reliability of the connector 1000.

[0116] Please refer to Fig.21and Fig. 22 In order to realize the linear connection between the locking member 4 and the second plug 2, in one embodiment of the present application, the locking member 4 includes a first shaft section 44, a second shaft section 45 and a third shaft section 46 which are connected in sequence; the shaft diameter of the second shaft section 45 is smaller than the shaft diameters of the first shaft section 44 and the third shaft section 46. With such a configuration, on the one hand, the second shaft section 45 can form an arc-shaped recess between the first shaft section 44 and the third shaft section 46, and when the locking member 4 contacts the locking surface 223 of the boss structure 22, the arc-shaped recess fits the locking surface 223, so that the point contact between the locking member 4 and the locking surface 223 is transformed into a line contact, thereby increasing the force bearing area of ​​the locking member 4 at the locking surface 223, improving the compressive strength of the locking member 4, and improving the reliability of the connector 1000.

[0117] On the other hand, the arc-shaped recess formed by the second shaft segment 45 can also clamp the boss structure 22, thereby optimizing the force applied to the locking member 4, reducing the possibility of flipping and slipping of the locking member 4 during contact with the boss structure 22, and improving the stability of the movement of the locking member 4.

[0118] It is understandable that in other possible implementations of the present application, an arc groove adapted to the outer contour of the locking member 4 may also be provided on the locking surface 223, and a linear connection between the locking member 4 and the locking surface 223 may also be achieved, and the present application does not impose any restrictions on this.

[0119] The number of locking members 4 can be one, two, or three, and this application does not limit this. In one embodiment of this application, the number of locking members 4 is set to three, and the three locking members 4 are evenly distributed around the first plug 1, so as to ensure the uniformity of the force applied to the second plug 2 and improve the reliability of the connector 1000.

[0120] Please refer to Figure 1 and Figure 2 The connector 1000 further includes a first piston 12 and a first elastic member 13, which are arranged in the first flow channel cavity 11. The first elastic member 13 may be a mechanical spring, a pneumatic spring, or a disc spring, which is not limited in the present application. The first spring is used to cooperate with the first piston 12 to seal the first flow channel cavity 11 when the first plug 1 and the second plug 2 are disconnected, thereby preventing the condensed medium in the first liquid cooling tube from flowing out of the first liquid cooling tube; when the first plug 1 and the second plug 2 are connected to each other, the first flow channel cavity 11 is avoided, thereby connecting the first liquid cooling tube, the first flow channel cavity 11 and the second flow channel cavity 23.

[0121] Specifically, the first flow channel cavity 11 includes a first cavity section 114 and a second cavity section 115 connected to each other; the diameter of the first cavity section 114 is smaller than the diameter of the second cavity section 115, and the first piston 12 is movably arranged between the first cavity section 114 and the second cavity section 115. The size of the first piston 12 is adapted to the cavity diameter of the first cavity section 114. When the first piston 12 is located in the first cavity section 114, the outer peripheral surface of the first piston 12 contacts the wall surface of the first cavity section 114 and forms a seal. One end of the first elastic member 13 is connected to the end of the first piston 12 away from the second plug 2, and the other end is connected to the cavity wall of the first flow channel cavity 11.

[0122] In actual application, when the second plug 2 is inserted into the first flow channel cavity 11 from the plug interface 113, the body of the second plug 2 will contact the first piston 12. Thereafter, as the second plug 2 continues to move, the first elastic member 13 is compressed under the push of the second plug 2, and the first piston 12 leaves the first cavity section 114 and reaches the second cavity section 115. The first flow channel cavity 11 is opened, and the first liquid cooling tube, the first flow channel cavity 11 and the second flow channel cavity 23 are connected. When the second plug 2 is withdrawn outward, the first elastic member 13 that loses the push of the second plug 2 will push the first piston 12 to move toward the first cavity section 114 under the action of elasticity. The first piston 12 contacts the cavity wall of the first cavity section 114, thereby sealing the first flow channel cavity 11, thereby preventing the condensing medium in the first liquid cooling tube from flowing out of the first liquid cooling tube, causing leakage of the condensing medium.

[0123] At the same time, due to the presence of the first elastic member 13, when the sleeve 3 is pulled backward by external force, the second plug 2 that is no longer restrained by the external force will move toward the plug interface 113 under the push of the first elastic member 13, thereby realizing the automatic pop-up of the second plug 2, reducing the difficulty of disassembling the second plug 2 and the first plug 1, and improving the convenience of using the connector 1000.

[0124] The connector 1000 also includes a second piston 24 and a second elastic member 25, which are arranged in the second flow channel cavity 23. The second elastic member 25 can be a mechanical spring, a pneumatic spring, or a disc spring, and this application does not limit this. The second spring is used to cooperate with the second piston 24 to seal the second flow channel cavity 23 when the first plug 1 and the second plug 2 are disconnected, thereby preventing the condensed medium in the second liquid cooling tube from flowing out of the first liquid cooling tube; when the first plug 1 and the second plug 2 are connected to each other, the second flow channel cavity 23 is avoided, so that the first liquid cooling tube, the first flow channel cavity 11, the second flow channel cavity 23 and the second liquid cooling tube are connected.

[0125] Specifically, the second flow channel cavity 23 has a third cavity section 231 and a fourth cavity section 232 connected to each other. The diameter of the third cavity section 231 is smaller than the diameter of the fourth cavity section 232. The size of the second piston 24 is adapted to the cavity diameter of the third cavity section 231. When the second piston 24 is located in the third cavity section 231, the outer peripheral surface of the second piston 24 contacts the wall surface of the third cavity section 231 and forms a seal. One end of the second elastic member 25 is connected to the end of the second piston 24 away from the first piston 12, and the other end is connected to the cavity wall of the second flow channel cavity 23.

[0126] Please refer to Figure 5 The connector 1000 further includes a snap ring 8, which is disposed in the fourth cavity section 232. The outer peripheral surface of the snap ring 8 contacts the cavity wall surface of the fourth cavity section 232 and is interference fit to be installed in the fourth cavity section 232. Correspondingly, a step surface is further provided on the side of the fourth cavity section 232 away from the third cavity section 231, and the step surface is used to provide a limit for the installation of the snap ring 8.

[0127] The end of the second elastic member 25 away from the second piston 24 is connected to the clamping ring 8. The arrangement of the clamping ring 8, on the one hand, can provide a step for the installation of the second elastic member 25, so as to reduce the difficulty of installing the second elastic member 25 in the second flow channel cavity 23, and on the other hand, the close fit between the clamping ring 8 and the second flow channel cavity 23 can effectively improve the sealing performance of the second plug 2, effectively prevent leakage between the second plug 2 and the second liquid cooling pipe, and ensure the stability and safety of the cooling system.

[0128] The connector 1000 also includes a gasket 9, which is arranged between the step surface and the snap ring 8. By increasing the number of gaskets 9 between the step surface and the snap ring 8, the relative position of the snap ring 8 in the fourth cavity section 232 can be adjusted, thereby improving the flexibility of the snap ring 8 for installing the second elastic member 25 and reducing the difficulty of installing the second elastic member 25.

[0129] The connector 1000 also includes a push member 6, which is arranged in the first flow channel cavity 11. In actual application, when the second plug 2 is inserted into the first flow channel cavity 11 from the plug interface 113, the first piston 12 is opened, the first flow channel cavity 11 is connected with the third cavity section 231, and the water flow in the first flow channel cavity 11 flows into the third cavity section 231. The water flow compresses the second elastic member 25 and pushes the second piston 24 to leave the third cavity section 231 and reach the fourth cavity section 232. The second flow channel cavity 23 is opened, and the first liquid cooling tube, the first flow channel cavity 11, the second flow channel cavity 23 and the second liquid cooling tube are connected. When the second plug 2 is withdrawn outward, the water flow disappears. The first elastic member 13, which loses the water flow push, will push the second piston 24 to move toward the third cavity section 231 under the action of elasticity. The second piston 24 contacts the cavity wall of the third cavity section 231 , thereby sealing the second flow channel cavity 23 , thereby preventing the condensed medium in the second liquid cooling tube from flowing out of the second liquid cooling tube, causing leakage of the condensed medium.

[0130] It can be understood that in the above embodiment, in order to ensure the sealing effect of the second piston 24 on the second flow channel cavity 23, the elastic coefficient of the second elastic member 25 should be set as large as possible, and too large an elastic coefficient will result in insufficient water flow to flush the second piston 24. To solve the above problem, in one embodiment of the present application, the connector 1000 also includes a push member 6, which is arranged in the first flow channel cavity 11. The push member 6 is used to extend into the second flow channel cavity 23 when the second plug 2 extends into the first flow channel cavity 11, and push the second piston 24 to move toward the fourth cavity section 232.

[0131] Specifically, the first piston 12 is provided with a through hole that penetrates along its axial direction, one end of the push member 6 is connected to the cavity wall of the first flow channel cavity 11, and the other end is penetrated in the through hole and sealed with the wall surface of the through hole. When the second plug 2 is inserted into the first flow channel cavity 11 from the plug interface 113, the push member 6 will extend into the second flow channel cavity 23 and contact the second piston 24 provided in the third cavity section 231 of the second flow channel cavity 23. Thereafter, as the second plug 2 continues to move, under the push of the push member 6, the second elastic member 25 is compressed, and the second piston 24 leaves the third cavity section 231 and reaches the fourth cavity section 232. The second flow channel cavity 23 is opened, and the first liquid cooling pipe, the first flow channel cavity 11, the second flow channel cavity 23 and the second liquid cooling pipe are connected. When the second plug 2 is withdrawn outward, the push member 6 withdraws from the second flow channel cavity 23, and the first elastic member 13, which loses the push of the push member 6, pushes the second piston 24 to move toward the third cavity section 231 under the action of elasticity. The second piston 24 contacts the cavity wall of the third cavity section 231, thereby sealing the second flow channel cavity 23, thereby preventing the condensed medium in the second liquid cooling tube from flowing out of the second liquid cooling tube, causing leakage of the condensed medium.
