Technical Field

[0001] This application relates to the field of connector technology, and in particular to a fixed valve core, a female connector, a fluid connector, and a liquid cooling device. Background Technology

[0002] With the continuous development of electronic technology, electronic devices are playing an increasingly important role in people's lives. Currently, fluid connectors are typically installed on the electronic components of electronic devices, allowing fluid to flow inside. This fluid flow helps to dissipate heat from the electronic components, thus cooling them. However, the fluid encounters significant resistance when flowing through the fixed valve core of the fluid connector, resulting in a relatively low flow rate. Utility Model Content

[0003] This application provides a fixed valve core, a female connector, a fluid connector, and a liquid cooling device to solve the problem of low fluid flow rate.

[0004] To solve the above problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a fixed valve core, the fixed valve core comprising: a first end, a connecting rod, and a second end connected in sequence, wherein the radial dimensions of the first end and the second end are both greater than the radial dimension of the connecting rod, and the first end is used to cooperate with the movable valve core of a female connector;

[0006] The second end portion includes an annular portion, a first connecting rod, and a second connecting rod. The first connecting rod and the second connecting rod are disposed opposite each other and have a first gap between them. The first end of the first connecting rod and the first end of the second connecting rod are both connected to the annular portion, and the second end of the first connecting rod and the second end of the second connecting rod are both connected to the connecting rod. A first through hole is provided on the annular portion, and the first through hole communicates with the first gap. The annular portion is used to be fixedly connected to the first housing of the female connector.

[0007] As an optional implementation, the diameter of the first through hole is equal to the dimension of the first gap along a first direction, where the first direction is the direction from the first connecting rod to the second connecting rod.

[0008] As an optional implementation, the fixed valve core further includes a first connecting portion, wherein the second end of the first connecting rod and the second end of the second connecting rod are both connected to the connecting rod through the first connecting portion, and the width of the first connecting portion gradually decreases along a second direction, the second direction being the direction in which the annular portion points to the connecting rod.

[0009] As an optional implementation, a guide portion is provided on the first connecting portion and on the surface facing the first gap. The guide portion includes a first guide slope and a second guide slope, and the distance between the first guide slope and the second guide slope gradually increases along the second direction.

[0010] As an optional implementation, the guide portion is a triangular prism guide portion.

[0011] As an optional implementation, a first annular groove is provided on the side wall of the first end, and a first sealing element is embedded in the first annular groove. The first sealing element is used to abut against the surface of the movable valve core.

[0012] Secondly, embodiments of this application provide a female connector, including a movable valve core, a first housing, and a fixed valve core as described in the first aspect. The movable valve core and the fixed valve core are both located within a channel of the first housing. The movable valve core is sleeved on the fixed valve core, and the movable valve core can move relative to the fixed valve core and the inner wall of the channel between a first position and a second position.

[0013] When the movable valve core is in the first position, the movable valve core and the fixed valve core seal the channel; when the movable valve core is in the second position, there is a second gap between the fixed valve core and the inner wall of the channel, and there is a third gap between the inner wall of the second through hole of the movable valve core and the fixed valve core, and the second gap, the third gap and the first through hole are connected.

[0014] As an optional implementation, the inner wall of the channel is provided with a second annular groove, the axis of the second annular groove coincides with the axis of the channel, and a second sealing element is embedded in the second annular groove;

[0015] When the movable valve core is in the first position, the outer wall of the movable valve core abuts against the second sealing element, and the inner wall of the second through hole of the movable valve core abuts against the first sealing element embedded in the first annular groove at the first end.

[0016] As an optional implementation, a first limiting member is provided on the inner wall of the channel, and a second limiting member is provided on the outer wall of the movable valve core;

[0020] Thirdly, embodiments of this application also provide a fluid connector, including a male connector and the female connector described in the second aspect, wherein the male connector is partially disposed within the female connector, and the male connector is used to control the opening or closing of the channel of the female connector.

[0021] As an optional implementation, the male connector includes a second housing and a male valve core, the male valve core being movably disposed within the second housing;

[0022] When the male connector is connected to the female connector, the second housing abuts against the movable valve core, and the second housing pushes the movable valve core to move away from the second housing; the fixed valve core abuts against the male valve core, and the fixed valve core pushes the male valve core to move away from the fixed valve core.

[0023] Fourthly, embodiments of this application also provide a liquid cooling device, including the fluid connector of the third aspect.

[0024] In this embodiment, since a first through hole is provided on the annular portion and the first through hole communicates with the first gap, compared with the way the fluid flows along the surface of the fixed valve core, in this embodiment, when the fluid flows through the fixed valve core, the fluid can flow to the first gap through the first through hole on the annular portion, which shortens the flow path of the fluid when flowing through the fixed valve core and reduces the resistance encountered by the fluid when flowing through the fixed valve core, thereby increasing the flow rate of the fluid.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The terms "first," "second," etc., used in the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices. Additionally, the use of "and / or" in this application indicates at least one of the connected objects, such as A and / or B and / or C, representing seven possibilities: including A alone, B alone, C alone, and the presence of both A and B, both B and C, both A and C, and the presence of A, B, and C.

[0046] Please see Figures 1 to 7 , Figure 1 This is a schematic diagram of the fixed valve core provided in an embodiment of this application. Figures 1 to 7 As shown, the fixed valve core 100 includes: a first end 110, a connecting rod 120 and a second end 130 connected in sequence, and the radial dimensions of the first end 110 and the second end 130 are both greater than the radial dimension of the connecting rod 120. The first end 110 is used to cooperate with the movable valve core of the female connector.

[0047] The second end portion 130 includes an annular portion 131, a first connecting rod 132, and a second connecting rod 133. The first connecting rod 132 and the second connecting rod 133 are disposed opposite to each other and have a first gap. The first end of the first connecting rod 132 and the first end of the second connecting rod 133 are both connected to the annular portion 131, and the second end of the first connecting rod 132 and the second end of the second connecting rod 133 are both connected to the connecting rod 120. A first through hole 1311 is provided on the annular portion 131, and the first through hole 1311 communicates with the first gap. The annular portion 131 is used to be fixedly connected to the first housing of the female connector.

[0048] The working principle of the embodiments of this application can be described as follows:

[0049] Because the annular portion 131 has a first through hole 1311 that communicates with the first gap, compared to the fixed valve core 100 where no through hole or gap is provided and the fluid needs to flow along the surface of the fixed valve core, where the two adjacent surfaces of the fixed valve core are usually set at a 90-degree right angle or acute angle, and the fluid usually encounters greater resistance when flowing through the aforementioned 90-degree right angle or acute angle, resulting in a lower fluid flow rate, in this embodiment, when the fluid flows through the fixed valve core 100, the fluid can flow to the first gap through the first through hole 1311 on the annular portion 131. This shortens the flow path of the fluid when flowing through the fixed valve core and significantly reduces the resistance encountered by the fluid when flowing through the fixed valve core 100, thereby increasing the fluid flow rate.

[0050] The specific application scenario of the fixed valve core 100 in this application embodiment is not limited. Optionally, the fixed valve core 100 can be applied in a cold plate type liquid cooling cabinet to connect the server water circuit and the liquid cooling cabinet water circuit. That is, the fluid flowing through the fixed valve core 100 can be cooling water flowing between the server water circuit and the liquid cooling cabinet water circuit.

[0051] Optionally, the first end 110 can be dumbbell-shaped, so that the first end 110 can be used to cooperate with the movable valve core of the female connector, thereby controlling the opening and closing of the water passage in the female connector.

[0052] Optionally, the radial dimension of the portion of the connecting rod 120 that is connected to the first end 110 gradually increases, i.e., the portion of the connecting rod 120 that is connected to the first end 110 is an inclined surface. This can further reduce the resistance encountered by the fluid when it flows from the connecting rod 120 to the first end 110.

[0053] The first link 132 and the second link 133 can have the same size and shape, which can improve the versatility of the first link 132 and the second link 133. When the first link 132 or the second link 133 is damaged, it is convenient to repair or replace the first link 132 and the second link 133, thereby reducing the repair or replacement cost.

[0054] The radial dimensions of the first end 110 and the second end 130 are both greater than the radial dimension of the connecting rod 120. This allows the connecting rod 120 to have a clearance fit with the first housing of the female connector, so that when the fixed valve core 100 and the movable valve core are engaged, the gap between the connecting rod 120 and the first housing can be used for fluid flow.

[0055] The specific shape of the annular portion 131 is not limited here. Optionally, the annular portion 131 can be a rectangular ring or a circular ring, etc.

[0056] The shape of the first through hole 1311 is not limited here. Optionally, the first through hole 1311 can be a round hole or an elliptical hole, etc.

[0057] The annular portion 131 of the second end 130 is fixedly connected to the first housing, so that the fixed valve core 100 can be fixed in the first housing and cannot move relative to the first housing, thereby enhancing the fixing effect of the entire fixed valve core.

[0058] As an optional implementation, the diameter of the first through hole 1311 is equal to the dimension of the first gap along a first direction, where the first direction is the direction from the first connecting rod 132 to the second connecting rod 133.

[0059] In this embodiment of the application, the diameter of the first through hole 1311 is equal to the dimension of the first gap along the first direction. In this way, the resistance encountered by the fluid when flowing from the first through hole 1311 to the first gap can be further reduced, thereby further increasing the flow rate of the fluid from the first through hole 1311 to the first gap.

[0060] It should be noted that the diameter of the first through hole 1311 is equal to the dimension of the first gap along the first direction, which can also ensure that there is no gradual contraction or expansion when the fluid flows from the annular part 131 to the connecting rod 120. This reduces local resistance and reduces the flow resistance when the fluid flows through the fixed valve core 100.

[0061] As an optional implementation, see [link to implementation details]. Figure 1 , Figure 2 and Figure 5 The fixed valve core 100 further includes a first connecting portion 140. The second end of the first connecting rod 132 and the second end of the second connecting rod 133 are both connected to the connecting rod 120 through the first connecting portion 140. The width of the first connecting portion 140 gradually decreases along a second direction, which is the direction in which the annular portion 131 points to the connecting rod 120.

[0062] The specific shape of the first connecting part 140 is not limited here. Optionally, the first connecting part 140 can be a triangular prism connecting part or an arc-shaped connecting part.

[0063] The width of the first connecting portion 140 may refer to the dimension along the first direction.

[0064] In this embodiment, the width of the first connecting portion 140 gradually decreases along a second direction, which is the direction from the annular portion 131 to the connecting rod 120. This enhances the connection strength between the first connecting rod 132 and the second connecting rod 133, thereby increasing the stability between them. Furthermore, since the width of the first connecting portion 140 gradually decreases along the second direction, the weight and volume of the first connecting portion 140 can be minimized while maintaining good connection strength between the first connecting rod 132 and the second connecting rod 133, thus reducing usage costs.

[0065] It should be noted that, optionally, the first link 132, the second link 133 and the first connecting part 140 can be an integrally formed structure, which can further enhance the connection strength between the first link 132, the second link 133 and the first connecting part 140.

[0066] As an optional implementation, see [link to implementation details]. Figure 1 , Figure 2 and Figure 5 A guide portion 150 is provided on the first connecting portion 140 and on the surface facing the first gap. The guide portion 150 includes a first guide slope and a second guide slope, and the distance between the first guide slope and the second guide slope gradually increases along the second direction.

[0067] The specific shape of the guide part 150 is not limited here. Optionally, the guide part 150 can be a triangular prism guide part. In this way, when the guide part 150 is a triangular prism guide part, the structure of the triangular prism guide part is stable, the strength is high, the service life is long, and the distance between the first guide slope and the second guide slope on the triangular prism guide part gradually increases more uniformly, so that the fluid flows more smoothly on the first guide slope and the second guide slope, which enhances the guiding effect on the fluid.

[0068] Alternatively, the cross-section of the guide portion 150 can be a semi-circular arc, that is, the guide portion 150 can be a semi-circular arc guide portion.

[0069] In this embodiment, since the distance between the first guide slope and the second guide slope gradually increases along the second direction, the resistance encountered by the fluid when flowing from the annular portion 131 to the connecting rod 120 is further reduced, thereby further improving the fluid flow rate.

[0070] Meanwhile, the first guide slope and the second guide slope can also guide the fluid. Since both the first guide slope and the second guide slope are slopes, when the fluid flows from the horizontal direction to the first guide slope and the second guide slope, the fluid can move along the direction of the first guide slope and the second guide slope, thereby changing the flow direction of the fluid from the horizontal direction to the direction of the first guide slope and the second guide slope. In other words, the first guide slope and the second guide slope can guide the fluid.

[0071] As an optional implementation, see [link to implementation details]. Figure 1 , Figure 2 and Figure 5 A first annular groove 111 is provided on the side wall of the first end 110, and a first sealing member 112 is embedded in the first annular groove 111. The first sealing member 112 is used to abut against the surface of the movable valve core 200.

[0072] The first sealing element 112 can be an annular ring, which can also be called an O-ring.

[0073] In this embodiment of the application, the first sealing member 112 is used to abut against the surface of the movable valve core 200. Thus, when the first sealing member 112 abuts against the surface of the movable valve core 200, thereby sealing the water passage between the movable valve core 200 and the fixed valve core 100, the first sealing member 112 has good sealing performance and can thus prevent leakage of the fluid.

[0074] Optionally, see Figures 8 to 11 This application provides a female connector 1000, including a movable valve core 200, a first housing 1001, and a fixed valve core 100 as described in the above embodiment. The movable valve core 200 and the fixed valve core 100 are both located in the channel of the first housing 1001. The movable valve core 200 is sleeved on the fixed valve core 100, and the movable valve core 200 can move relative to the fixed valve core 100 and the inner wall of the channel between a first position and a second position.

[0075] When the movable valve core 200 is in the first position, the movable valve core 200 and the fixed valve core 100 seal the channel; when the movable valve core 200 is in the second position, there is a second gap between the fixed valve core 100 and the inner wall of the channel, and there is a third gap between the inner wall of the second through hole of the movable valve core 200 and the fixed valve core 100, and the second gap, the third gap and the first through hole 1311 are connected.

[0076] In this embodiment of the application, the female connector 1000 includes a movable valve core 200 and the aforementioned fixed valve core 100. The channel can be understood as the water passage inside the female connector 1000. Thus, by moving the movable valve core 200 between the first position and the second position, the closing and opening of the channel can be controlled, thereby enhancing the control effect of closing and opening the water passage.

[0077] As an optional implementation, see [link to implementation details]. Figure 10 and Figure 11 The inner wall of the channel is provided with a second annular groove 210, the axis of the second annular groove 210 coincides with the axis of the channel, and a second sealing element 220 is embedded in the second annular groove;

[0078] When the movable valve core 200 is in the first position, the outer wall of the movable valve core 200 abuts against the second sealing member 220, and the inner wall of the second through hole of the movable valve core 200 abuts against the first sealing member 112 embedded in the first annular groove of the first end 110.

[0079] When the movable valve core 200 is in the second position, the outer wall of the movable valve core 200 can be separated from the second seal 220, and the inner wall of the second through hole of the movable valve core 200 can be separated from the first seal 112 embedded in the first annular groove of the first end 110.

[0080] In this embodiment, a second annular groove 210 is provided on the inner wall of the channel, and a second sealing element 220 is embedded in the second annular groove. Thus, when the movable valve core 200 is in the first position, the outer wall of the movable valve core 200 abuts against the second sealing element 220, and the inner wall of the second through hole of the movable valve core 200 abuts against the first sealing element 112 embedded in the first annular groove of the first end 110, thereby further enhancing the sealing effect inside the channel when the channel is closed.

[0081] As an optional implementation, see [link to implementation details]. Figure 10 The inner wall of the channel is provided with a first limiting member 160, and the outer wall of the movable valve core 200 is provided with a second limiting member 230.

[0082] When the movable valve core 200 is in the first position, the first limiting member 160 abuts against the second limiting member 230.

[0083] When the movable valve core 200 is in the second position, the first limiting member 160 can be separated from the second limiting member 230.

[0084] In this embodiment, when the movable valve core 200 is in the first position, the first limiting member 160 abuts against the second limiting member 230, which enhances the limiting effect on the movable valve core 200.

[0085] As an optional implementation, see [link to implementation details]. Figure 10 Both the first limiting member 160 and the second limiting member 230 are inclined limiting members, and the inclination of the inclined surfaces of the first limiting member 160 and the second limiting member 230 are matched.

[0086] In this embodiment of the application, the first limiting member 160 and the second limiting member 230 are both inclined limiting members, and the inclination of the inclined surfaces of the first limiting member 160 and the second limiting member 230 are matched. In this way, the limiting effect between the first limiting member 160 and the second limiting member 230 can be better.

[0087] As an optional implementation, see [link to implementation details]. Figure 10 The channel is also provided with a first elastic element 240, which is used to drive the movable valve core 200 to move from the second position to the first position.

[0088] In this embodiment of the application, the first elastic element 240 is used to drive the movable valve core 200 to move from the second position to the first position, thereby enhancing the driving effect on the movable valve core 200.

[0089] It should be noted that when the first elastic element 240 recovers its deformation, it can drive the movable valve core 200 to move from the second position to the first position.

[0090] Optionally, see Figures 16 to 18 This application embodiment also provides a fluid connector, including a male connector 2000 and the aforementioned female connector 1000. The male connector 2000 is partially inserted into the female connector 1000, and the male connector 2000 is used to control the opening or closing of the channel of the female connector 1000.

[0091] Optionally, when the male connector 2000 is partially inserted into the female connector 1000, the male connector 2000 can push the movable valve core 200 inside the female connector 1000 from a first position to a second position, thereby opening the channel of the female connector 1000 and allowing fluid to flow within the channel; when the male connector 2000 is at least partially separated from the female connector 1000, the movable valve core 200 can move from the second position to the first position, thereby closing the channel of the female connector 1000.

[0092] In this embodiment, since the fluid connector provided in this embodiment includes the female connector 1000 in the above embodiment, it has the same beneficial technical effects as the above embodiment. The specific structure of the female connector 1000 can be referred to the corresponding description in the above embodiment, and will not be repeated here.

[0093] As an optional implementation, see [link to implementation details]. Figures 12 to 15 The male connector 2000 includes a second housing 2001 and a male valve core 2002, wherein the male valve core 2002 is movably disposed within the second housing 2001;

[0094] When the male connector 2000 is connected to the female connector 1000, the second housing 2001 abuts against the movable valve core 200, and the second housing 2001 pushes the movable valve core 200 to move away from the second housing 2001; the fixed valve core 100 abuts against the male valve core 2002, and the fixed valve core 100 pushes the male valve core 2002 to move away from the fixed valve core 100.

[0095] The process of connecting the male connector 2000 and the female connector 1000 can be understood as the process of the male connector 2000 gradually being inserted into the female connector 1000. In this way, the second housing 2001 pushes the movable valve core 200 to move away from the second housing 2001, so that the movable valve core 200 moves to the position of the connecting rod 120 of the fixed valve core 100. At this time, the fluid flow channel inside the female connector 1000 is opened. Meanwhile, the fixed valve core 100 pushes the male valve core 2002 to move away from the fixed valve core 100, thereby opening the fluid flow channel inside the male connector 2000. Thus, the fluid flow channels inside both the male connector 2000 and the female connector 1000 are opened, forming a fluid channel, allowing fluid to flow through the fluid connectors.

[0096] When the male connector 2000 and the female connector 1000 are gradually disconnected, the movable valve core 200 can move toward the direction of the second housing 2001, and the male valve core 2002 can move toward the direction of the fixed valve core 100.

[0097] In this embodiment, the second housing 2001 can push the movable valve core 200 to move, and the fixed valve core 100 can push the male valve core 2002 to move. This further enhances the driving effect on the movable valve core 200 and the male valve core 2002. The movable valve core 200 and the male valve core 2002 can be driven without the need for additional driving components, thus reducing the cost of use.

[0098] Optionally, see Figure 14 A second elastic element 2003 may also be provided inside the second housing 2001. The second elastic element 2003 is connected to the male valve core 2002 and can be used to drive the male valve core 2002 to move within the second housing 2001. A threaded interface may be formed on the inner wall of the second housing 2001.

[0099] For example, the second elastic element 2003 can limit the male valve core 2002 to the initial position. When the male connector 2000 is gradually inserted into the female connector 1000, the fixed valve core 100 pushes the male valve core 2002 to move away from the fixed valve core 100. At this time, the second elastic element 2003 is in a compressed state, and the channel in the male connector 2000 is in an open state. When the connection between the male connector 2000 and the female connector 1000 is gradually disconnected, under the action of the elastic deformation restoring force of the second elastic element 2003, the male valve core 2002 can be driven to move to the initial position.

[0100] Optionally, the male valve core 2002 can be cylindrical, with its outer diameter gradually increasing in the middle section. There is a ramp surface between the initial and maximum outer diameters. Simultaneously, the inner wall of the second housing 2001 has a matching ramp surface corresponding to the position of the male valve core 2002. When the male valve core 2002 is in its initial position, its ramp surface is close to the ramp surface of the inner wall of the second housing 2001, blocking the water passage. When the male valve core 2002 moves under external force, its ramp surface gradually deviates from the ramp surface of the inner wall of the second housing 2001, thus opening the water passage.

[0101] It should be noted that, optionally, the male connector 2000 and the female connector 1000 are respectively provided with mutually cooperating locking components. In this way, the connection effect between the male connector 2000 and the female connector 1000 can be enhanced through the cooperation of the locking components.

[0102] Alternatively, the connection between the male connector 2000 and the female connector 1000 can be achieved by applying an external force. When an external force is applied to the male connector 2000 and the female connector 1000, they are connected. When the external force is removed, the connection between the male connector 2000 and the female connector 1000 can be disconnected.

[0103] Optionally, this application embodiment also provides a liquid cooling device including the fluid connector described above. Thus, since the liquid cooling device provided in this application embodiment includes the fluid connector from the above embodiments, it has the same beneficial technical effects as the above embodiments, and the specific structure of the fluid connector can be found in the corresponding descriptions in the above embodiments, which will not be repeated here.

[0104] The above description represents the preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
