Technical Field

The present application relates to the technical field of connectors, and more specifically, to a connecting end, a fluid connector, a sealing element, and a liquid cooling device.

Background technique

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.

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.

In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

Common connection ends achieve switching between open and closed states through the movement of the valve core in the valve seat. However, since the valve core moves relative to the valve seat, it is difficult to achieve precise sealing between the valve core and the valve seat under different states through a simple structure.

Summary of the invention

In view of this, the purpose of the present application is to provide a connection end, a fluid connector, a liquid cooling device and a seal, which achieve precise sealing between the valve core and the valve seat under different conditions through a simple sealing structure, reduce or even eliminate the adverse effects on the fluid flow state, and have less resistance to the movement of the valve core.

In order to achieve the above objectives, this application provides the following technical solutions:

A sealing member is arranged between the valve core and the valve seat, and the sealing member includes a first sealing portion and a second sealing portion. The first sealing portion is annular and is arranged on the valve core along the edge of the through hole or is arranged on the valve seat along the edge of the flow channel. The second sealing portion is annular and is at least partially sleeved outside the first sealing portion and is spaced apart from the first sealing portion.

Using the connection end provided by the present application, the seal between the matching surface of the valve core and the valve seat adopts the method of matching the first sealing part and the second sealing part. The first sealing part is arranged on the valve core along the edge of the through hole or on the valve seat along the edge of the flow channel, so that when the valve core moves to the state where the through hole and the flow channel are open, an effective seal can be formed between the matching surface of the valve core and the valve seat, and the fluid is not easy to enter between the matching surfaces of the valve core and the valve seat, that is, the fluid can better flow along the flow channel formed by the flow channel and the through hole, 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 cooperates with the first sealing part, and the flow channel and the through hole are both located within the hollow range of the second sealing part during the movement of the valve core from the open state with the flow channel to the disconnected state.

The second sealing portion cooperates with the first sealing portion, and the first flow opening and the second flow opening are both located within the hollow range of the second sealing portion during the movable member moves from the open state to the disconnected state, so the second sealing portion ensures that the movable member can always maintain a seal with the main member within the range of movement. In summary, the seal provided in the present application can achieve effective sealing between the movable part and the mating surface of the main part within the movable range. At the same time, it reduces the influence of the mating surface on the fluid flow state when the movable part is in the open state. The contact area between the seal and the movable part and the main part is small, so the resistance to the movement of the movable part is small, thereby facilitating the operation of opening or disconnecting the connection end.

Detailed ways

The embodiments of the present application disclose a connecting end, a fluid connector, a liquid cooling device and a sealing member to achieve precise sealing between the valve core and the valve seat under different conditions, reduce or even eliminate turbulence caused by the flow of fluid along the mating surface of the valve core and the valve seat, and create less resistance to the movement of the valve core to facilitate the opening or closing operation of the valve core.

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.

The connection end provided in the present application includes but is not limited to cooperating with another connection end. When the fluid source is disconnected, the two connection ends are sealed separately; when the two connection ends are butted, they are opened respectively, so that the two connection ends 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 to be in an open state, the connection end is opened; when the valve core moves to the through hole and the flow channel to be staggered to be in a disconnected state, the connection end is closed. It can be understood that the through hole of the valve core and the flow channel are connected, which means that the through hole and the flow channel are at least partially opposite to each other for connection, or that the through hole and the flow channel are directly opposite to each other for connection, so that the fluid in the flow channel can flow from one end of the flow channel through the through hole into the other end of the flow channel, and the connection end is opened. The through hole and the flow channel of the valve core are staggered, which means that the through hole and the flow channel are completely staggered to be not connected, so that the fluid in the flow channel cannot flow under the blocking effect of the valve core, that is, the connection end is closed. Specifically, when the valve core moves to the point where the through hole and the flow channel are directly opposite, the connection end is opened, and when the valve core moves to the point where the through hole and the flow channel are completely offset, the connection end is closed.

In order to achieve the seal between the valve core and the valve seat, a seal needs to be arranged between the two. The inventors of the present application found in the process of realizing the present invention that if a seal ring is arranged between the valve core and the valve seat, a seal ring needs to be arranged on the edge of the valve seat or the valve core to ensure that the valve core is always sealed during the movement of the valve core. However, when the through hole is connected to the flow channel, the fluid, especially the high-pressure fluid when the connection end is used for the liquid cooling device, is easy to enter the matching surface of the valve core and the valve seat, and flow back from the matching surface, thereby forming turbulence. Turbulence will make the flow of the fluid unstable, and make the fluid flow in the channel lose stability, thereby increasing the resistance of the fluid and increasing the energy loss. In addition, in addition to energy loss, it is also easy to cause problems such as vibration and noise of components, which reduces the performance of the connection end. The inventors of the present application also found in the process of realizing the present invention that if a sealing gasket is arranged between the valve core and the valve seat, although a wide range of sealing can be achieved, the contact area between the sealing gasket and the valve core and the valve seat is large, and the valve core is subject to large resistance from the sealing gasket when the valve core moves, so that its movement is hindered and the reliability of the connection end is reduced.

In order to overcome the above-mentioned defects, the present application proposes a connecting end, whose sealing element adopts a first sealing part and a second sealing part to cooperate with each other, which can achieve reliable sealing between the valve core and the valve seat, reduce the risk of causing turbulence, reduce the resistance to the movement of the valve core, improve the reliability of the connecting end and reduce energy loss.

In the following embodiments, the structure of the sealing member and the matching mode between the sealing member and the valve core and the valve seat are mainly described.

In a specific embodiment, referring to FIGS. 1 to 5 , the connection end 10 provided in the present application includes a valve seat 100, a valve core 200 and a sealing member 300. A flow channel 110 is provided in the valve seat 100. The valve core 200 is movably provided on the valve seat 100, and a through hole 210 is provided on the valve core 200. The valve core 200 can move to the point where the through hole 210 is connected to the flow channel 110 to be in an open state, and can move to the point where the through hole 210 is staggered from the flow channel 110 to be in a disconnected state. The sealing member 300 is disposed between the valve core 200 and the valve seat 100. The 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 210 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 on all sides. The specific shape is set according to the shape of the through hole 210 when it is disposed on the valve core 200, and is set according to the shape of the flow channel 110 when it is disposed on the valve seat 100. The second sealing portion 320 is annular and at least partially sleeved outside the first sealing portion 310 and at least partially spaced from the first sealing portion 310. When the valve core 200 moves from the through hole 210 and the flow channel 110 to be in the open state to the staggered state to be in the disconnected state, the flow channel 110 and the through hole 210 are both located in the hollow range of the second sealing portion 320. Similarly, the shape of the second sealing portion 320 can be either an annular shape or other shapes that are closed on all sides. The second sealing portion 320 can be arranged on the valve core 200 or on the valve seat 100. When the second sealing portion 320 is arranged on the valve core 200, the second sealing portion 320 follows the range of movement of the valve core 200, and the flow channel 110 is located in the second sealing portion 320; when the second sealing portion 320 is arranged on the valve seat 100, the movement trajectory of the through hole 210 is within the hollow range of the second sealing portion 320. The forms of the first sealing portion 310 and the second sealing portion 320 include, but are not limited to, sealing material rings such as rubber rings and silicone rings.

By using the connecting end 10 provided in the present application, the sealing member 300 between the matching surfaces of the valve core 200 and the valve seat 100 adopts a method of matching a first sealing portion 310 with a second sealing portion 320. The first sealing portion 310 is arranged on the valve core 200 along the edge of the through hole 210 or is arranged on the valve seat 100 along the edge of the flow channel 110. Therefore, when the valve core 200 moves to the state where the through hole 210 is connected with the flow channel 110 to be opened, an effective seal can be formed between the matching surfaces of the valve core 200 and the valve seat 100. As shown in Figures 2 and 3, 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 better flow along the flow channel formed by the flow channel 110 and the through hole 210, thereby 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 210 are both located within the hollow range of the second sealing part 320 during the process of the valve core 200 moving from being connected with the flow channel 110 to being in an open state to being staggered to being in a disconnected state, as shown in Figures 4 and 5. Therefore, the second sealing part 320 ensures that the valve core 200 can always maintain a seal with the matching surface of the valve seat 100 within the range of its movement. In summary, the connecting end 10 provided in the present application realizes an effective seal between the valve core 200 and the valve seat 100 within the range of its movement, and at the same time, reduces the influence of the matching surface of the valve core 200 on the fluid flow state in the open state, and the contact surface between the 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 connecting end 10.

In some embodiments, please refer to FIG. 6 , the first sealing portion 310 and the second sealing portion 320 are an integrated structure. The first sealing portion 310 and the second sealing portion 320 are integrally formed, which is convenient for forming and assembly with the connecting end 10, and the integral structure can play a role in structural reinforcement. At the same time, in the installed state, the first sealing portion 310 and the second sealing portion 320 can form a limiting effect on each other, so that the installation of the two is more reliable, and it is not easy to move during the activity of the valve core 200 to affect the sealing effect. In other embodiments, the first sealing portion 310 and the second sealing portion 320 can also be separately provided.

In some embodiments, please refer to FIG. 6 , a portion of the first sealing portion 310 is formed as a portion of the second sealing portion 320. That is, the first sealing portion 310 and the second sealing portion 320 are partially shared. When the sealing member 300 is arranged on the valve core 200, the second sealing portion 320 is sleeved outside the through hole 210 and the portion shared with the first sealing portion 310 is along the edge of the through hole 210; when the sealing member 300 is arranged on the valve seat 100, the second sealing portion 320 is sleeved outside the flow channel 110 and the portion shared with the first sealing portion 310 is along the edge of the flow channel 110. As set above, reliable sealing is achieved while greatly reducing the contact area between the sealing member 300 and the valve core 200 and the valve seat 100.

In some embodiments, please refer to FIG. 6 , the first sealing portion 310 is a circular ring sealing ring, the second sealing portion 320 includes a first arc portion 321, a second arc portion 322, a third arc portion 323 and a straight portion 324, the third arc portion 323 and the straight portion 324 are respectively connected between the first arc portion 321 and the second arc portion 322, the first arc portion 321 is formed as a part of the circular ring sealing ring, the second arc portion 322 has the same radius of curvature as the first arc portion 321, the center line of the third arc portion 323 is tangent to the center line of the first arc portion 321 and the center line of the second arc portion 322, and the center line of the straight portion 324 is tangent to the center line of the first arc portion 321 and the center line of the second arc portion 322. It can be understood that the first sealing portion 310 is in the shape of a circular ring, which is suitable for the cross-section of the flow channel 110 and the through hole 210 to be circular. The first arc portion 321 can block the fluid when the valve core 200 moves to the state where the through hole 210 and the flow channel 110 are open, and the second arc portion 322 can be located at the edge of the flow channel 110 or the through hole 210 to block the fluid when the valve core 200 moves to the state where the through hole 210 and the flow channel 110 are disconnected. The third arc portion 323 and the straight portion 324 achieve a smooth transition of the overall structure, avoid stress concentration, and have good elasticity at each position to provide reliable sealing.

Furthermore, the valve core 200 is rotatably disposed on the valve seat 100, and the second sealing portion 320 is disposed on the valve core 200 and adopts the above-mentioned configuration, so that the third arc portion 323 can always be along the edge of the flow channel 110 when the valve core 200 rotates to maintain the seal between the valve core 200 and the valve seat 100, and the straight portion 324 can not only maintain the seal between the valve core 200 and the valve seat 100, but also make the path connecting the first arc portion 321 and the third arc portion 323 as short as possible, thereby reducing the resistance of the second sealing portion 320 to the rotation of the valve core 200 as much as possible. Specifically, in the case where the valve core 200 is rotatably disposed on the valve seat 100, the third arc portion 323 can be disposed along the edge of the matching surface of the valve core 200 and the valve seat 100. In other embodiments, the second sealing portion 320 can also be in a circular ring shape.

In some embodiments, please refer to FIG. 7 , sealing grooves 220 are respectively provided on opposite sides of the valve core 200, and sealing members 300 are provided in both sealing grooves 220. The sealing grooves 220 include a circular annular groove 221 and a U-shaped groove 222 that are connected to each other. The inner wall surfaces of the circular annular groove 221 and the U-shaped groove 222 are connected by an arc transition. The cross sections of the first sealing portion 310 and the second sealing portion 320 are both circular. The outer diameters of the first sealing portion 310 and the second sealing portion 320 are greater than the depth of the sealing groove 220. The first sealing portion 310 is a circular annular sealing ring and is provided in the circular annular groove 221. Part of the second sealing portion 320 is formed as a part of the circular annular sealing ring, and the remaining part gradually increases in cross section from one end connected to the first sealing portion 310 to the other end and is separated from the first sealing portion 310. The separated part is located in the U-shaped groove 222. As set above, it is convenient to install the sealing member 300. And the sealing member 300 has a stable and reliable structure and good durability, thereby ensuring the sealing effect of the valve core 200 and the valve seat 100. It is particularly suitable for the case where the valve core 200 is rotatably disposed on the valve seat 100 , and the rotation axis of the valve core 200 is parallel to the axis of the through hole 210 .

In some embodiments, the first sealing portion 310 and the second sealing portion 320 are made of the same material to facilitate molding. In other embodiments, the first sealing portion 310 and the second sealing portion 320 may also be made of different materials, such as the hardness of the first sealing portion 310 is greater than the hardness of the second sealing portion 320, so that the sealing force of the second sealing portion 320 is better than the sealing force of the first sealing portion 310, so that even if the fluid flows out through the first sealing portion 310 due to unexpected factors during use, the second sealing portion 320 can still play a sealing role, further improving the reliability of the seal between the valve core 200 and the valve seat 100.

In some embodiments, the second sealing portion 320 is provided on the valve core 200, and the second sealing portion 320 is provided along the shortest path of the projection trajectory around the flow channel 110, and the projection trajectory of the flow channel 110 is the trajectory formed by the projection of the flow channel 110 on the valve core 200 within the range of movement of the valve core 200. The valve core 200 is movably provided on the valve seat 100, that is, the valve core 200 can move relative to the valve seat 100, which is usually the case that the valve seat 100 remains stationary, and the valve core 200 moves relative to the valve seat 100. For example, the trajectory formed by the projection of the flow channel 110 on the valve core 200 within the range of movement of the valve core 200 is provided with the second sealing portion 320 along the shortest path around the trajectory. If the relative movement between the valve core 200 and the valve seat 100 is regarded as the valve core 200 being stationary and the valve seat 100 rotating relative to the valve core 200, the second sealing portion 320 is provided around the shortest path of the movement trajectory of the flow channel 110. The second sealing portion 320 is configured as above, which can achieve effective sealing and at the same time the length of the second sealing portion 320 is the shortest, thereby minimizing the resistance to the movement of the valve core 200.

In some embodiments, the second sealing portion 320 is disposed on the valve seat 100, and the second sealing portion 320 is disposed along the shortest path of the activity track around the through hole 210. The valve core 200 is movably disposed on the valve seat 100, that is, the valve core 200 can move relative to the valve seat 100, and within the range of movement of the valve core 200, the through hole 210 on the valve core 200 forms a corresponding activity track, and the second sealing portion 320 is disposed around the shortest path of the track, which can achieve effective sealing and at the same time, the length of the second sealing portion 320 is the shortest, thereby minimizing the resistance to the movement of the valve core 200.

In some embodiments, sealing members 300 are respectively provided between the two sides of the valve core 200 and the valve seat 100. When the valve core 200 is disposed as a whole inside the valve seat 100, sealing members 300 of the above structure are respectively provided between the two sides of the valve core 200 and the valve seat 100, so that reliable sealing with the valve seat 100 can be achieved from both sides of the valve core 200. In other embodiments, when one end of the valve core 200 extends from the valve seat 100 and is used to cooperate with the other connecting end 10, the sealing member 300 of the above structure is provided between the inner side of the valve core 200 and the valve seat 100.

In some embodiments, the valve core 200 is rotatably disposed on the valve seat 100. The valve core 200 is rotatably disposed, and the positional relationship between the through hole 210 and the flow channel 110 is switched by its rotation. The rotational arrangement of the valve core 200 occupies a small space, and the corresponding movement stroke of the valve core 200 required to realize the opening and closing states of the connection end 10 is small, so the required size of the sealing member 300 is small, which further reduces the resistance of the sealing member 300 to the rotation of the valve core 200, and the way the valve core 200 rotates is also convenient for the arrangement of the sealing member 300. Specifically, the rotation axis of the valve core 200 is parallel to the axis of the through hole 210.

Furthermore, the valve core 200 is rotatably arranged on the valve seat 100, and the valve seat 100 is used to cooperate with the valve seat 100 of the other connecting end 10, and the valve seat 100 can rotate relative to the valve seat 100 of the other connecting end 10 and drive the valve core 200 of the other connecting end 10 to rotate, so as to synchronously open or close the two connecting ends 10.

In some embodiments, part of the second sealing portion 320 is in an arc shape, and the center of the arc is located at the rotation axis. As configured above, when the second sealing portion 320 rotates with the valve core 200, the arc-shaped portion can better seal the flow channel 110, and when the second sealing portion 320 is disposed on the valve seat 100, the arc-shaped portion can better seal the through hole 210.

The present invention also provides a fluid connector. In some embodiments, please refer to Figures 8 and 9. The fluid connector includes a male end and a female end, and at least one of the male end and the female end is any one of the connection ends 10 in the above embodiments. Since the fluid connector adopts the connection end 10 in the above embodiments, please refer to the above embodiments for the beneficial effects of the fluid connector.

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 11 on the male end face is connected to the female end flow port 12 on the female end face to be in an open state and staggered to be in a disconnected state. 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.

In some embodiments, an end face seal 20 is provided between the male end face and the female end face. The end face seal 20 includes a first end face seal portion 21 and a second end face seal portion 22. The first end face seal portion 21 is annular and is arranged at the male end along the edge of the male end flow opening 11 or at the female end along the edge of the female end flow opening 12; the second end face seal portion 22 is annular and at least partially sleeved outside the first end face seal portion 21 and spaced from the first end face seal portion 21. During the process of the male end and the female end moving from the open state of the male end flow opening 11 and the female end flow opening 12 to the disconnected state, the male end flow opening 11 and the female end flow opening 12 are both located within the hollow range of the second seal portion 320.

The end face seal 20 can be specifically arranged in the same principle as the seal 300 arranged between the valve core 200 and the valve seat 100 in the above embodiments, which will not be described in detail here. To facilitate the arrangement of the end face seal 20, an installation groove for installing the end face seal 20 can be arranged on the male end face or the female end face.

Based on the fluid connector or connection end 10 provided in the above embodiment, the present invention further provides a liquid cooling device, which includes any one of the fluid connectors or connection ends 10 in the above embodiment. Since the liquid cooling device adopts the fluid connector or connection end 10 in the above embodiment, please refer to the above embodiment for the beneficial effects of the liquid cooling device.

The present application also provides a sealing member 300. In some embodiments, the sealing member 300 is used to be arranged between a main member and a movable member that are movably matched to achieve sealing between the main member and the movable member. The main member is provided with a first flow opening, and the movable member is provided with a second flow opening. The movable member can move until the second flow opening is connected to the first flow opening and the second flow opening is staggered with the first flow opening. The sealing member 300 includes:

A first sealing portion 310, which is annular and is used to be disposed on the movable member and along the edge of the second flow opening or disposed on the main member and along the edge of the first flow opening;

The second sealing part 320 is annular and at least partially sleeved outside the first sealing part 310 and at least partially spaced apart from the first sealing part 310. When the movable part moves from a connected state to a staggered state between the second flow port and the first flow port, the first flow port and the second flow port are both located within the hollow range of the second sealing part 320.

The seal 300 provided in the present application is applied and arranged between the movable part and the main part, and the first seal part 310 is arranged on the movable part along the edge of the second flow opening or on the main part along the edge of the first flow opening, so that when the movable part rotates to the state where the second flow opening is connected to the first flow opening, an effective seal can be formed between the mating surfaces of the movable part and the main part, and the fluid is not easy to enter between the mating surfaces of the movable part and the main part, that is, the fluid can better flow along the flow channel formed by the first flow opening and the second flow opening, reducing or even eliminating the radial flow of the fluid between the mating surfaces, avoiding the turbulence caused thereby, and further avoiding the energy loss, noise and other problems caused by the turbulence. The second seal part 320 cooperates with the first seal part 310, and the first flow opening and the second flow opening are both located in the hollow range of the second seal part 320 during the movable part's movement from the state of being connected to the first flow opening to the staggered state. Therefore, the second seal part 320 ensures that the movable part can always maintain a seal with the mating surface of the main part within the range of movement. In summary, the seal 300 provided in the present application can achieve effective sealing within the movable range of the movable part and the main part, and at the same time, reduce the influence of the mating surface on the fluid flow state when the movable part is in the open state. The contact area between the seal 300 and the movable part and the main part is small, so the resistance to the movement of the movable part is small, thereby facilitating the operation of opening or disconnecting the connecting end 10.

In some embodiments, the movable part and the main body may be the valve core 200 and the valve seat 100 in the above embodiments. In other embodiments, the movable part and the main body may also be two connecting ends 10. The specific shape of the sealing member 300 may refer to the corresponding configuration of the sealing member 300 in the above connecting end 10, and will not be repeated here.

In some embodiments, the sealing member 300 provided in the present application is used to be disposed between the valve core 200 and the valve seat 100 of the connection end 10 to achieve sealing between the matching surfaces of the valve core 200 and the valve seat 100, and the sealing member 300 includes:

A first sealing portion 310, which is annular and is used to be disposed on the valve core 200 and along the edge of the through hole 210 of the valve core 200 or disposed on the valve seat 100 and along the edge of the flow channel 110 of the valve seat 100, wherein the valve core 200 is movably disposed in the valve seat 100, and the valve core 200 can move to the point where the through hole 210 is connected to the flow channel 110 and the through hole 210 is staggered from the flow channel 110;

The second sealing portion 320 is annular and at least partially sleeved outside the first sealing portion 310 and spaced apart from the first sealing portion 310. When the valve core 200 moves from a connected state with the flow channel 110 to a staggered state, the flow channel 110 and the through hole 210 are both located within the hollow range of the second sealing portion 320.
