Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to a connecting end, a fluid connector and a liquid cooling device. Background Art

[0002] At present, the Internet of Everything requires higher and higher computing speeds for various chips, resulting in higher and higher heat dissipation requirements for chips. Traditional air cooling can no longer meet the heat dissipation needs of chips, and various new types of fluid heat sinks are about to become the mainstream of chip heat dissipation. Fluid connectors are interfaces between fluid sources and various chip heat sinks.

[0003] A fluid connector usually includes two matching connection ends, which can have the same or different structures. When the fluid source is disconnected, the two connection ends are sealed separately to prevent fluid leakage and spraying; when the two connection ends are connected, their respective sealing structures are opened, so that the fluid source and the fluid radiator are connected, and the fluid circulates to take away the heat, achieving the effect of efficient heat dissipation.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in the prior art:

[0005] A common connection end includes a valve core and a valve seat. The valve core is usually integrally arranged inside the valve seat. There is a flow channel inside the valve seat, and the flow channel extends to the end surface of the valve seat. The valve core is provided with a through hole. The valve core moves to change the relative position of the through hole and the flow channel to achieve the switching of the connection end between the open and closed states. However, since the fluid pressure in the connection end is usually relatively large, when the valve core is closed, the pressure of the fluid on the valve core and the friction force on the movement of the valve core make the movement resistance of the valve core relatively large, so it is more laborious to perform corresponding operations on the connection end. Therefore, it is necessary to provide a connection end, a fluid connector and a liquid cooling device to solve the above technical problems. Utility Model Content

[0037] The embodiment of the utility model discloses a connecting end, a fluid connector and a liquid cooling device. The valve core of the connecting end can directly contact the docking end, and no sealing is required between the outer end surface of the valve core and the valve body, which reduces the resistance of the sealing structure to the valve core, facilitates operation, and is not easy to form turbulence.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The connection end provided in the present application is used for connection with the docking end, and the structure of the docking end may be the same as or partially different from the structure of the connection end. When the fluid source is disconnected, the connection end and the docking end are sealed separately; when the connection end and the docking end are docked, they are opened respectively, so that the connection end and the docking end can form a connected fluid channel. The connection end includes a valve seat and a valve core, and the valve core is constrained to be able to move within a preset range relative to the valve seat. A through hole is provided on the valve core, and a flow channel is provided on the valve seat, and when the valve core moves to the through hole and the flow channel are connected, the connection end is opened, and when the valve core moves to the through hole and the flow channel are staggered, the connection end is closed. Specifically, the connection end is opened when the valve core moves to the through hole and the flow channel, and the connection end is closed when the valve core moves to the through hole and the flow channel are staggered. It can be understood that the through hole of the valve core is connected to the flow channel, which can refer to the through hole and the flow channel being at least partially opposite to each other for connection, or the through hole and the flow channel being opposite to each other for connection, so that the fluid in the flow channel can flow out from one end of the flow channel through the through hole, and the connection end is opened. The through hole of the valve core and the flow channel are staggered, which means that the through hole and the flow channel are completely staggered and not connected, so that the fluid in the flow channel cannot flow due to the blocking effect of the valve core, that is, the connection end is closed.

[0040] In order to achieve the sealing of the overall connecting channel and the outside world when the connecting end and the docking end are docked, sealing gaskets need to be provided between the two sides of the valve core and the valve body, and between the two valve seats for sealing. In the process of realizing the present application, the inventor of the present application found that sealing gaskets are provided between the two sides of the valve core and the valve seat, and between the two valve seats, and the damping force formed by the sealing gaskets will become a resistance to the rotation of the valve core. And in the case of poor sealing, the fluid is easy to flow on the matching surface between the two sides of the valve core and the valve seat, thereby forming turbulence. In order to overcome the above-mentioned defects, the present application proposes a connecting end, which reduces the resistance to the rotation of the valve core and the risk of causing turbulence through the structural design of the valve core and the valve seat. In the following embodiments, the structure and matching method of the valve core and the valve seat are mainly described.

[0041] In some embodiments, see Figure 1-Figure 2 The connection end provided by the utility model includes a valve seat 100, a valve core 200 and a first sealing member 300. A flow channel 110 is provided in the valve seat 100, and an end of the valve seat 100 has an opening 120. The valve core 200 is movably provided on the valve seat 100, for example, axially movably provided on the valve seat 100, and the outer end of the valve core 200 is penetrated through the opening 120 so that the outer end surface 230 of the valve core 200 can contact and cooperate with the docking end, and the through hole 201 of the outer end surface 230 of the valve core 200 is directly connected to the docking end without passing through the flow channel 110 on the valve seat 100 of the connection end. It can be understood that the opening 120 is connected with the flow channel 110, and the shape of the opening 120 can be the same as or different from the shape of the flow channel 110. The valve core 200 is provided with a through hole 201 extending to the outer end face 230 of the valve core 200. If the size of the opening 120 is larger than the size of the through hole 201, the outer end face can be used to cooperate with the docking end corresponding to the connection end, and the valve core 200 can move until the through hole 201 is connected with the flow channel 110 and the through hole 201 is staggered with the flow channel 110. That is, the outer end face 230 of the valve core 200 is exposed from the opening 120, that is, the outer end face 230 of the valve core 200 is used as a matching surface for matching with the docking end, which can be directly matched with the valve core 200 at the docking end, or directly matched with the valve seat 100 at the docking end, and the through hole 201 of the valve core 200 is directly connected with the docking end. It can be understood that the docking end can be another connection end, or an interface, pipe fitting, etc. of other structures. Specifically, the outer end face 230 of the valve core 200 is flush with the outer end face of the valve seat 100 or protrudes from the outer end face of the valve seat 100, so as to facilitate matching with the docking end. It is understood that one end of the through hole 201 extends to the outer end surface 230 of the valve core 200, that is, the orifice formed by the outer end surface 230 of the valve core 200 serves as an interface of the connection end. The first sealing member 300 is disposed between the inner end surface 240 of the valve core 200 and the valve seat 100 to seal the valve core 200 and the valve seat 100. It is understood that the first sealing member 300 has an avoidance hole that is connected to the flow channel 110 and the through hole 201 when the flow channel 110 and the through hole 201 are in a relative state, so as to achieve effective sealing while ensuring the normal opening or closing cooperation of the valve core 200 and the valve seat 100.

[0042] When the connection end provided by the utility model is applied, an opening 120 is provided on the valve seat 100, and one end of the valve core 200 is penetrated through the opening 120, then the valve core 200 can cooperate with the docking end, so that the through hole 201 of the valve core 200 is directly connected with the docking end, so that there is no need to seal between the outer end of the valve core 200 and the valve seat 100, and only the first sealing member 300 is provided between the inner end face 240 of the valve core 200 and the valve seat 100, so the structure is simplified, and the resistance formed by the sealing structure to the movement of the valve core 200 is reduced, so that the switching operation of opening and closing the connection end is more time-saving and labor-saving, and the labor intensity of the operator is reduced, and the work efficiency is improved. At the same time, the valve core 200 directly cooperates with the docking end, avoiding the flow of the fluid along the matching surface between the outer end face 230 of the valve core 200 and the valve seat 100 and the turbulence caused thereby, thereby avoiding the energy loss, noise and other problems caused by the turbulence.

[0043] In some embodiments, the valve core 200 is rotatably disposed on the valve seat 100, and a limiting portion for limiting the axial movement of the valve core 200 is provided on the valve seat 100. The valve core 200 is rotatably disposed, and its rotation is used to switch the positional relationship between the through hole 201 and the flow channel 110. The rotational setting space of the valve core 200 is small, and the corresponding movement stroke of the valve core 200 required to realize the opening and closing states of the connecting end is small, which is conducive to the miniaturization design of the connecting end, and the way the valve core 200 rotates is also convenient for the setting of the seal. Specifically, the rotation axis of the valve core 200 is parallel to the axis of the through hole 201. By setting the limiting portion, the valve core 200 is limited to the valve seat 100 and cannot be disengaged, and the limiting portion can guide the rotation of the valve core 200, so that its rotation is more stable.

[0044] In some embodiments, one end of the valve seat 100 is provided with a mounting groove for mounting the valve core 200, the side wall 131 of the mounting groove is provided with a flange 140, the valve core 200 includes a main body 210 and a boss 220 protruding from one end of the main body 210, the limiting portion includes an inner end surface of the flange 140 and a bottom surface 132 of the mounting groove, the inner end surface of the flange 140 cooperates with the end surface of the main body 210 provided with the boss 220, and the bottom surface 132 of the mounting groove cooperates with the other opposite end surface of the main body 210. The side wall 131 of the mounting groove is also its peripheral surface, and the bottom surface 132 of the mounting groove is an end surface connected to the edge of the peripheral surface, and cooperates with the inner end surface 240 of the valve core 200. It can be understood that the protruding direction of the flange 140 should be toward one side of the valve core 200. Specifically, it can protrude toward the valve core 200 along the radial direction of the valve seat 100. The flange 140 can be annular to limit the valve core 200 as a whole from the circumferential direction, or the flange 140 can be strip-shaped or block-shaped, and multiple flanges 140 are arranged at intervals along the circumferential direction, so that the axial limit of the valve core 200 can be achieved from different circumferential angles. The valve core 200 adopts a protruding setting at one end, and the main body 210 is provided with an end face of a boss 220, that is, a step surface 211 formed between the boss 220 and the main body 210, which cooperates with the inner end face of the flange 140 to achieve limit, specifically such as clearance fit. The other end face of the main body 210 opposite to the step surface 211 cooperates with the bottom surface 132 of the mounting groove to achieve limit, specifically such as clearance fit. As set above, the structure is simple and the limit is reliable.

[0045] Furthermore, the flange 140 surrounds the opening 120, and the boss 220 is disposed through the opening 120. The flange 140 is formed by extending from one end edge of the valve seat 100 toward the valve core 200, and the limiter is disposed at the edge, which not only serves as a limiter, but also serves as a protective function. Specifically, the inner circumference of the flange 140 is clearance-matched with the outer circumference of the boss 220.

[0046] In some embodiments, the valve seat 100 includes a valve seat body 150 and an end cover 160, the valve seat body 150 and the end cover 160 form a mounting groove, and the valve core 200 is arranged between the valve seat body 150 and the end cover 160. By providing the valve seat 100 with a split structure, the assembly of the valve core 200 is facilitated, and the difficulty of assembly and processing is reduced. Specifically, the end surface of the valve seat body 150 forms the bottom surface 132 of the mounting groove, the end cover 160 includes an outer peripheral portion sleeved outside the end of the valve seat body 150 and a flange 140 connected to the outer peripheral portion, the main body 210 of the valve core 200 is arranged between the flange 140 and the end surface of the valve seat body 150, and the boss 220 is arranged at the opening 120 surrounded by the flange 140. Specifically, the end cover 160 and the valve seat body 150 can be detachably connected by threaded connection, which is convenient for disassembly and assembly and reliable for connection. Furthermore, the threaded connection can adjust the distance between the end cover 160 and the valve seat body 150 according to the different thicknesses of the main body 210 of the valve core 200, so that the connection end has better adaptability and can be adapted to valve cores 200 of different specifications.

[0047] In some embodiments, a ball bearing is provided between the boss 220 and the flange 140. In order to further reduce the resistance to the rotation of the valve core 200, a ball bearing is provided between the boss 220 and the flange 140. Therefore, even if friction occurs between the boss 220 and the flange 140, the rolling friction force is significantly smaller than the sliding friction force of the direct contact between the two, thereby reducing the resistance to the rotation of the valve core 200. In other embodiments, the friction between the boss 220 and the flange 140 can also be reduced by means of clearance fit, coating on the mating surface of the boss 220 and the flange 140, etc.

[0048] In some embodiments, a retractable limiting protrusion is provided on one of the outer circumference of the valve core 200 and the inner circumference of the valve seat 100, and an annular groove cooperating with the limiting protrusion is provided on the other, and the limiting portion includes a limiting protrusion or an annular groove provided on the inner circumference of the valve seat 100. This embodiment is different from the setting of the limiting portion in the above-mentioned embodiment. In this embodiment, the limiting portion includes a limiting protrusion or an annular groove provided on the inner circumference of the valve seat 100, and an annular groove cooperating with the upper limiting protrusion of the valve seat 100 or a limiting protrusion cooperating with the annular groove on the valve seat 100 is provided on the outer circumference of the valve core 200. Taking the example of a retractable limiting protrusion provided on the outer circumference of the valve core 200 and an annular groove provided on the inner circumference of the valve seat 100, during assembly, the limiting protrusion retracts due to the action of the inner circumference of the valve seat 100, and when the valve core 200 is assembled to the point where the limiting protrusion is opposite to the annular groove, the limiting protrusion can extend outward to insert into the annular groove, so that when the valve core 200 rotates, the limiting protrusion slides along the annular groove to play an axial limiting role. Specifically, an elastic member is provided in cooperation with the limiting protrusion, and the elastic member is used to drive the limiting protrusion to extend outward. In other embodiments, a threaded hole can also be provided on the valve seat 100, and the limiting protrusion is threadedly matched with the threaded hole, and the limiting protrusion is screwed in to insert into the annular groove or screwed out to exit the annular groove through the threaded match, thereby facilitating the assembly of the valve core 200. In summary, while the axial limiting of the valve core 200 is achieved by adopting the above-mentioned setting, the valve seat 100 can conveniently disassemble and assemble the valve core 200 without providing a split structure. Specifically, in this embodiment, the flow channel 110 may be connected to the end of the valve seat 100 and serve as an opening 120 that cooperates with the outer end of the valve core 200, that is, the inner circumferential surface of the valve seat 100 may extend in the axial direction.

[0049] In some embodiments, see Figure 3-Figure 4 , the outer end surface 230 of the valve core 200 is provided with a sealing groove 202 for installing the second sealing member 400, and the second sealing member 400 is used for sealing between the valve core 200 and the butt end. In order to facilitate the sealing between the connection end and the butt end, the sealing groove 202 is provided on the outer end surface 230 of the valve core 200. When the valve core 200 is butt-jointed with the butt end, the sealing between the two valve cores 200 is achieved by providing the second sealing member 400 in the sealing groove 202. Of course, the second sealing member 400 should be provided with an avoidance hole that cooperates with the through hole 201, so as to achieve effective sealing of the two valve cores 200 without affecting the normal operation of the valve core 200.

[0050] In some embodiments, the first sealing member 300 includes a first sealing portion 310 and a second sealing portion 320. The first sealing portion 310 is annular and is disposed on the valve core 200 along the edge of the through hole 201 or on the valve seat 100 along the edge of the flow channel 110. The second sealing portion 320 is annular and at least partially sleeved outside the first sealing portion 310 and spaced from the first sealing portion 310. When the valve core 200 moves from the state of communication with the flow channel 110 to the staggered state, the flow channel 110 and the through hole 201 are both located in the hollow range of the second sealing portion 320. The first sealing portion 310 is annular and is disposed on the valve core 200 along the edge of the through hole 201 or on the valve seat 100 along the edge of the flow channel 110. It can be understood that the annular shape here is not limited to a circular ring shape, but also includes other shapes that are closed all around. The specific shape is set according to the shape of the through hole 201 when it is set on the valve core 200, and is set according to the shape of the flow channel 110 when it is set on the valve seat 100. The second sealing part 320 is annular and at least partially sleeved outside the first sealing part 310 and spaced from the first sealing part 310. When the valve core 200 moves from the state of communication with the flow channel 110 to the staggered state, the flow channel 110 and the through hole 201 are both located within the hollow range of the second sealing part 320. Similarly, the shape of the second sealing part 320 can be either annular or other shapes that are closed on all sides. The second sealing part 320 can be provided on the valve core 200 or on the valve seat 100. When the second sealing part 320 is provided on the valve core 200 and the second sealing part 320 moves within the range of the valve core 200, the flow channel 110 is located within the second sealing part 320; when the second sealing part 320 is provided on the valve seat 100, the moving track of the through hole 201 is within the hollow range of the second sealing part 320. The forms of the first sealing part 310 and the second sealing part 320 include but are not limited to sealing material rings such as rubber rings and silicone rings. When the valve core 200 moves to the state where the through hole 201 is connected to the flow channel 110, an effective seal can be formed between the valve core 200 and the valve seat 100, and the fluid is not easy to enter between the matching surfaces of the valve core 200 and the valve seat 100, that is, the fluid can flow better along the flow channel formed by the flow channel 110 and the through hole 201, reducing or even eliminating the radial flow of the fluid between the matching surfaces, avoiding the turbulence caused thereby, and further avoiding the energy loss, noise and other problems caused by the turbulence. The second sealing part 320 cooperates with the first sealing part 310, and the flow channel 110 and the through hole 201 are both located within the hollow range of the second sealing part 320 during the movement of the valve core 200 from the state of being connected to the flow channel 110 to the staggered state. Therefore, the second sealing part 320 ensures that the valve core 200 can always maintain a seal with the valve seat 100 within the range of movement.The first sealing member 300 is arranged as above, so as to realize effective sealing between the valve core 200 and the valve seat 100 within the movable range of the valve core 200. At the same time, it reduces the influence of the matching surface of the valve core 200 on the fluid flow state when the valve core 200 is in the open state. Moreover, the contact surface between the first sealing member 300 and the valve core 200 and the valve seat 100 is small, so the resistance to the movement of the valve core 200 is small, thereby facilitating the operation of opening or disconnecting the connection end.

[0051] Specifically, the first sealing portion 310 and the second sealing portion 320 are an integrated structure. Further, part of the first sealing portion 310 is formed as part of the second sealing portion 320. That is, the first sealing portion 310 and the second sealing portion 320 are partially shared. The above arrangement facilitates molding and assembly with the connection end, and while achieving reliable sealing, the contact area between the seal and the valve core 200 and the valve seat 100 is greatly reduced.

[0052] In some embodiments, the valve core 200 is rotatably disposed on the valve seat 100, and the valve seat 100 is used to cooperate with the valve seat 100 of the other connection end, and the valve seat 100 can rotate relative to the valve seat 100 of the other connection end and drive the valve core 200 of the other connection end to rotate, so as to synchronously open or close the two connection ends. Specifically, a push groove is provided on the valve core 200, and a push part is provided on the valve seat, and the push groove is used for the push part on the other connection end to insert and drive the valve core 200 to move, so as to open or close the flow channel 110.

[0053] In some embodiments, the side wall of the opening 120 is provided with a groove, and the groove and the outer peripheral surface of the valve core 200 form a slide groove 170, and the push portion on the other connecting end can be inserted into the slide groove 170 and slide along the slide groove 170. The push groove on the valve core 200 is opposite to the slide groove 170, so that the push portion on the other connecting end can pass through the slide groove 170 and be inserted into the push groove to drive the valve core 200 to move.

[0054] Furthermore, the slide groove 170 is also used to axially lock the push part on the other connection end with the valve seat 100. Specifically, the axial locking of the slide groove 170 and the push part on the other connection end can be formed by the push part and the slide groove 170 to form an undercut structure to limit the axial position. And the size of one end of the slide groove 170 is larger than the size of the undercut to facilitate the insertion and removal of the push part. When connecting, hold the two valve seats 100 with both hands, insert the push parts of the valve seats 100 into the corresponding slide grooves 170 of the other connection end, and the end faces of the two valve cores 200 are in contact, and the two hands rotate in opposite directions. At this time, the push parts drive the opposite valve cores 200 to rotate until the two connection ends are connected at the same time, and the undercut structure axially locks the two valve seats 100. When disconnecting, just rotate the valve seats in the opposite directions mentioned above, and when the push part rotates to one end of the slide groove 170, it can be pulled out of the slide groove 170.

[0055] In some embodiments, the valve core 200 is provided with a first locking hole 203 and a second locking hole, the valve seat 100 is provided with a mounting hole 120, and the connecting end includes a locking pin 500 movably disposed in the mounting hole 120 along the axial direction. When the valve core 200 moves to the state of opening the flow channel 110, the locking pin 500 is locked in the first locking hole 203, and when the valve core 200 moves to the state of closing the flow channel 110, the locking pin 500 is locked in the second locking hole. It can be understood that the ability of the locking pin 500 to move along the axial direction of the valve core 200 includes both the axial translation of the locking pin 500 and the axial expansion and contraction of the locking pin 500. By setting the locking pin 500, when the valve core 200 moves to the open position, that is, the entire flow channel 110 forms a passage, and the connection end is in the open state, the locking pin 500 is inserted into the first locking hole 203, thereby locking the position of the valve core 200, that is, the valve core 200 cannot continue to rotate relative to the valve seat 100, so that the connection end can be reliably maintained in the open state. When the valve core 200 moves to the closed position, the locking pin 500 is inserted into the second locking hole, thereby locking the position of the valve core 200, that is, the valve core 200 cannot continue to move relative to the valve seat 100, so that the connection end can be reliably maintained in the closed state. In addition, through the cooperation of the locking pin 500 with the first locking hole 203 and the second locking hole, it is possible to provide a reminder of the rotation position of the valve core 200 when the connection end is opened or closed, such as a sound reminder, a hand feeling reminder caused by different resistances, etc., and the structure is simple and the positioning is accurate. And through the cooperation of a locking pin 500 with the first locking hole 203 and the second locking hole, the structure is simple. When the valve core 200 is rotatably disposed on the valve seat 100 , the first locking hole 203 and the second locking hole may be distributed along the circumferential direction.

[0056] The utility model also provides a fluid connector. In some embodiments, refer to Figure 3 The fluid connector includes a male end and a female end, at least one of which is a connection end of any one of the above embodiments. Since the fluid connector adopts the connection end of the above embodiments, please refer to the above embodiments for the beneficial effects of the fluid connector.

[0057] In some embodiments, the male end and the female end are both connection ends of any one of the above embodiments, and the male end and the female end are detachably connected to each other, and the male end and the female end can be relatively rotated until the male end flow port on the male end face is connected and staggered with the female end flow port on the female end face. Specifically, when the male end and the female end rotate relatively, the valve seat 100 of the male end drives the valve core 200 of the female end to rotate, and the valve seat 100 of the female end drives the valve core 200 of the male end to rotate, so as to synchronously open or close the male end and the female end.

[0058] In some embodiments, a second sealing member 400 is disposed between the outer end surface 230 of the male valve core 200 and the outer end surface 230 of the female valve core 200. By disposing the second sealing member 400 between the two valve cores 200, the sealing between the two valve cores 200 is directly achieved.

[0059] The utility model also provides a fluid connector. In some embodiments, the fluid connector includes a connecting end and a docking end. Both the connecting end and the docking end include a valve seat 100 and a valve core 200. A flow channel 110 is provided in the valve seat 100. The valve core 200 can be movably disposed on the valve seat 100. A through hole 201 is provided on the valve core 200. The valve core 200 can move until the through hole 201 is connected to the flow channel 110 and the through hole 201 is staggered from the flow channel 110. When the connecting end and the docking end are docked, the valve core 200 of the connecting end contacts the valve core 200 or the valve seat 100 of the docking end and the flow channel 110 of the connecting end is connected to the flow channel 110 of the docking end. When the connecting end and the docking end are separated, the connecting end and the docking end are closed respectively. That is, the outer end surface 230 of the valve core 200 at the connection end is used as the mating surface for mating with the butt end. The outer end surface 230 of the valve core 200 at the connection end can be directly mated with the valve core 200 at the butt end, or can be directly mated with the valve seat 100 at the butt end. The through hole 201 of the outer end surface 230 of the valve core 200 at the connection end is directly connected with the butt end without passing through the flow channel 110 on the valve seat 100 at the connection end. Specifically, the valve core 200 at the connection end is directly mated with the valve core 200 at the butt end, that is, the outer end surface 230 of the valve core 200 at the connection end is mated with the outer end surface 230 of the valve core 200 at the butt end, and the through holes 201 of the two are directly connected. Specifically, the connection end of the fluid connector can adopt any one of the connection ends in the above-mentioned embodiments.

[0060] By using the fluid connector provided by the utility model, the valve core 200 at the connecting end can directly contact and cooperate with the docking end, so that there is no need to seal between the outer end of the valve core 200 at the connecting end and the valve seat 100, and only a sealing structure needs to be set between the inner end surface 240 of the valve core 200 and the valve seat 100. Therefore, the structure is simplified, and the resistance of the sealing structure to the movement of the valve core 200 is reduced, thereby making the switching operation of opening and closing the connecting end more time-saving and labor-saving, reducing the labor intensity of the operator and improving work efficiency.
