[0006] In view of this, the purpose of this utility model is to provide a fluid connector and a liquid cooling system, which simplifies the structure of the fluid connector.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fluid connector includes two connection ends; each connection end includes a valve body and a valve cover disposed outside the valve body. The valve body has a valve body channel, and the valve cover has a valve cover through hole. The valve cover is rotatably connected to the valve body so that rotation of the valve cover opens the corresponding valve body channel by connecting the valve cover through hole, or closes the corresponding valve body channel by offsetting the valve cover through hole. The valve covers of the two connection ends are detachably connected to form a control structure. In the control structure, each valve cover can rotate synchronously, and the valve cover through holes of different valve covers are correspondingly connected along the axial direction. Rotation of the control structure connects or disconnects the valve body channels of the two connection ends.

[0017] A liquid cooling system, including the fluid connector described above.

[0018] The fluid connector provided by this utility model includes two connection ends; each connection end includes a valve body and a valve cover disposed outside the valve body. The valve body has a valve body channel, and the valve cover has a valve cover through hole. The valve cover is rotatably connected to the valve body so that by rotating the valve cover, the valve cover through hole is connected to open the corresponding valve body channel, or staggered to close the corresponding valve body channel. The valve covers of the two connection ends are detachably connected to form a control structure.

The valve body channel on the connection end is opened or closed by rotating the valve cover on the valve body. After the two connection ends are assembled, the valve body channel of the male end matches the valve body channel of the female end, and the valve covers of the two connection ends are connected to form a control structure. By rotating this control structure, the valve covers of the two connection ends can move synchronously, enabling the connection and disconnection between the matched valve body channels.

[0021] This type of fluid connector allows the valve body channel of a single connection end to be opened or closed by rotating the valve cover located outside the valve body. Furthermore, the on / off control of the fluid connector can be achieved by rotating the control structure formed by the detachable connection of the valve covers of the two connection ends. Thus, the on / off function of the fluid connector can be guaranteed solely by the valve covers located outside the valve body and the connection between the valve covers, eliminating the need for complex linkage or transmission structures in each connection end. This simplifies the structure and reduces assembly difficulty. Moreover, the detachable connection between the valve covers located outside the valve body in the two connection ends provides ample operating space and also reduces the difficulty of assembling and disassembling the connection ends.

[0033] Connector 4. Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The core of this invention is to provide a fluid connector and a liquid cooling system, which simplifies the structure of the fluid connector.

[0036] For a specific embodiment of the fluid connector provided by this utility model, please refer to [link / reference]. Figures 1 to 6 It includes two connecting ends 1, which can be male end 11 and female end 12 arranged sequentially along the axial direction.

[0037] The connecting end 1 includes a valve body 2 and a valve cover 3 disposed outside the valve body 2. The valve body 2 is provided with a valve body channel 21, which specifically penetrates the valve body 2 axially. The valve cover 3 is provided with a valve cover through hole 311, which specifically penetrates the valve cover 3 axially. The valve cover 3 is rotatably connected to the valve body 2.

[0038] In each connection end 1, by rotating the valve cover 3, the valve cover through hole 311 can be connected to the corresponding valve body channel 21 to open the corresponding valve body channel 21, thereby opening the valve body channel 21 of the connection end 1. Alternatively, by rotating the valve cover 3, the valve cover through hole 311 can be offset from the corresponding valve body channel 21 to close the corresponding valve body channel 21. In this case, the valve body channel 2111 and each valve cover through hole 311 are completely offset and are blocked and sealed by the plate surface on the valve cover 32, thereby closing the valve body channel 21 of the connection end 1.

[0039] In the connection end 1, one or more valve body channels 21 and valve cover through holes 311 can be provided, and multiple channels can be two, three, five, etc. When multiple valve body channels 11 are provided, each valve body channel 21 is connected to one or more corresponding valve cover through holes 311 when the connection end 1 needs to be connected. Specifically, in the same connection end 1, each valve body channel 21 is connected to different valve cover through holes 311, such as... Figure 3 and Figure 4 As shown, both the male end 11 and the female end 12 have two valve body channels 21 and two valve cover through holes 311. When open, the two valve cover through holes 311 in the male end 11 are connected to the two valve body channels 21 one-to-one, and the two valve cover through holes 311 in the female end 12 are connected to the two valve body channels 21 one-to-one. Alternatively, a single valve cover through hole 311 can be provided, with a larger area, so that it can rotate with the valve cover 3 to simultaneously connect to all valve body channels 21 in the same connecting end 1.

[0040] It should be noted that, unless otherwise specified, the axial direction in the embodiments of this application generally refers to the extension direction of the axis of rotation that rotates relative to the valve cover 3 and the valve body 2, and the circumferential and radial directions are also based on this axis of rotation. In addition, in the two connecting ends 1, the axes of rotation of the valve cover 3 and the valve body 2 that rotate relative to each other can be arranged collinearly.

[0041] like Figure 5 and Figure 6 As shown, the valve covers 3 of the two connecting ends 1 are detachably connected to form a control structure. In the control structure formed by the connection of the valve covers 3, each valve cover 3 can rotate synchronously, and the valve cover through holes 311 of different valve covers 3 are correspondingly connected along the axial direction. By rotating the control structure, each valve cover 3 also rotates synchronously, thereby connecting or disconnecting the valve body channels 21 of the two connecting ends 1.

[0042] It should be noted that when the valve covers 3 of the two connecting ends 1 are connected, the valve cover through holes 311 of the two connecting ends 1 remain connected. That is, the valve cover through hole 311 of the male end 11 and the valve cover through hole 311 of the female end 12 are always in a connected state. Thus, through the synchronous rotation of the valve cover 3 of the male end 11 and the valve cover 3 of the female end 12, the axial connection and disconnection of the valve body channel 21 of the male end 11 and the valve body channel 21 of the female end 12 can be realized.

[0043] like Figure 5 As shown, the valve cover 3 of the male end 11 is the male valve cover 34, and the valve cover 3 of the female end 12 is the female valve cover 33. The two are connected to form a circumferentially limiting control structure, enabling the male valve cover 34 and the female valve cover 33 to rotate synchronously. By applying force to either the male valve cover 34 or the female valve cover 33, the entire control structure can be rotated. When the control structure rotates to a certain angle, as... Figure 5The connecting end on the right side is the male end 11, and the valve body channel 21 in the male end 11 is connected to the valve cover through hole 311; at the same time, as Figure 5 The left-hand connecting end is the female end 12. The valve body channel 21 in the female end 12 is connected to the valve cover through hole 311, so that the valve body channels 21 of the two connecting ends 1 are connected, and the fluid connector is in the connected / open state. At this time, the flow channel of the fluid connector includes, along the axial direction, the valve body channel 21 of the male end 11, the valve cover through hole 311 in the male end 11, the valve cover through hole 311 of the female end 12, and the valve body channel 21 of the female end 12.

[0044] like Figure 6 As shown, after the control structure rotates to another angle, as... Figure 6 The connecting end on the right side is the male end 11. The valve body channel 21 in the male end 11 is offset from the valve cover through hole 311. Meanwhile, as... Figure 6 The left-hand connection end is the female end 12. The valve body channel 21 in the female end 12 is offset from the valve cover through hole 311, so that the valve body channel 21 of the male end and the valve body channel 21 of the female end are blocked and isolated by the plate surface of the male end valve cover 34 and the female end valve cover 33 without valve cover through hole 311. The fluid connector is in the disconnected and closed state.

[0045] When using the above-mentioned fluid connector, the pipeline is connected through the valve body 2 in the connection end 1, and the pipeline is connected to one end of the valve body channel 21. The valve body channel 21 on the connection end 1 is opened or closed by rotating the valve cover 3 on the valve body 2. After the two connection ends 1 are assembled, the valve body channel 21 of the male end 11 is matched with the valve body channel 21 of the female end 12, and the valve covers 3 of the two connection ends 1 are connected to form a control structure. By rotating the control structure alone, the valve covers 3 of the two connection ends 1 can move synchronously, realizing the connection and disconnection between the matched valve body channels 21.

[0046] This type of fluid connector can achieve the opening and closing of the valve body channel 21 of a single connection end by rotating the valve cover 3 located outside the valve body 2. Furthermore, the opening and closing control of the fluid connector can be achieved by rotating the control structure formed by the detachable connection of the valve covers 3 of the two connection ends. While ensuring the opening and closing function of the fluid connector, there is no need to set up complex linkage or transmission structures in each connection end, which simplifies the structure and reduces the assembly difficulty. Moreover, the two connection ends 1 are detachably connected between the valve covers 3 located outside the valve body 2, with sufficient operating space, which can also reduce the difficulty of assembly and disassembly between the connection ends.

[0047] Furthermore, to achieve a detachable connection between the two valve covers 3 in the control structure, such as... Figure 1As shown, connecting structures are respectively provided on the valve covers 3 of the two connecting ends 1 to achieve a detachable connection between the valve covers 3. Specifically, the connecting structure is a plug-in structure. In this case, the valve plates 3 are axially plugged in, resulting in a simple structure that is easy to assemble. Specifically, the plugging can be completed during the axial approach of the two valve covers 3. Furthermore, after plugging, a circumferential limit is formed between the plugged structures. Therefore, during rotation, the synchronous rotation of each valve cover 3 in the control structure can be achieved through the plug-in structure. At this time, the plug-in structure has an interaction force in the circumferential direction to achieve synchronous rotation of the valve covers 3 of the two connecting ends 1. In other embodiments, the detachable connection between the two valve covers 3 may also include other forms, such as bolt connections, snap-fit ​​connections, etc. Specifically, a detachable connection can be achieved through one or at least two methods, for example, using a combination of plug-in and snap-fit ​​connections.

[0048] For example, such as Figure 1 As shown, in one of the two connecting ends 1, the valve cover 3 of one end is provided with one or more slots 332, and the valve cover 3 of the other end is provided with inserts 341 that are axially corresponding to each slot 332. Specifically, the slots 332 and inserts 341 are inserted one-to-one. At this time, as the two connecting ends 1 approach each other axially, the corresponding insertion of the slots 332 and inserts 341 can be directly achieved, which is convenient to operate. After insertion, the valve cover 3 of the male end 11 and the valve cover 3 of the female end 12 are simultaneously circumferentially limited. During rotation, the inserts 341 circumferentially push the groove wall of the slot 332, or the groove wall of the slot 332 axially pushes the inserts 341, so as to achieve synchronous rotation of the valve covers 3 of the two connecting ends 1. Alternatively, in other embodiments, one connecting end 1 may be provided with inserts and slots, and the other connecting end 1 may be adapted to be provided with slots and inserts that are respectively inserted and matched with the inserts and slots of the first connecting end 1.

[0049] For example, in one of the two connecting ends 1, the valve cover 3 of one is provided with slots 332 that are not uniformly arranged in the circumferential direction, and the valve cover 3 of the other is provided with a plug 341 that is inserted into the slots 332 in the axial direction, thereby realizing the foolproof design between the valve covers 3 of the two connecting ends 1 during the assembly process.

[0050] It should be noted that when one insertion block 341 and one slot 332 are provided, they can be directly regarded as being non-uniformly arranged on the corresponding valve cover 3. When multiple insertion blocks 341 and slots 332 are provided, for the insertion blocks 341, non-uniform arrangement includes: the circumferential angle and / or circumferential spacing and / or radial position between adjacent insertion blocks 341 are not completely the same, and / or, the shape or size of each insertion block 341 is not completely the same; for the slots 332, non-uniform arrangement includes: the circumferential angle and / or circumferential spacing and / or radial position between adjacent slots 332 are not completely the same, and / or, the shape or size of each slot 332 is not completely the same.

[0051] For example, in Figure 3 and Figure 4 In the illustrated embodiment, one of the two connecting ends 1 has only one slot 332 on its valve cover 3, and the other has only one insert 341 on its valve cover 3. Specifically, the male valve cover 34 has only one insert 341, and the female valve cover 33 has only one slot 332, and the two are inserted into each other. In addition, the slot 332 can be a square groove, and the insert 341 can be a rectangular body; or, the slot 332 can be a wavy groove, a triangular groove, a trapezoidal groove, etc., and the shape of the insert 341 is adapted to the slot 332. Specifically, after insertion, the groove wall of the slot 332 and the insert 341 can fit completely.

[0052] For example, if at least part of the connection structure is exposed in the fluid connector, the connection structure is well visible during the axial assembly of the two connection ends 1. Specifically, it is visible from the radially outer side, so the two connection ends 1 can be aligned by means of the connection structure, thereby improving assembly efficiency.

[0053] For example, such as Figure 1 and Figure 4 As shown, the connection structures of the two connecting ends 1 are a slot 332 and a plug 341, respectively. The slot 332 penetrates the corresponding valve cover 3 radially, and the plug 341 protrudes radially from the outer circumferential surface of the corresponding valve cover 3. The radial penetration of the slot 332 reduces machining difficulty and provides better visibility, facilitating accurate alignment of the slot 332 and plug 341 during the axial connection of the two connecting ends 1. Furthermore, as... Figure 1 As shown, with both connection ends 1 connected, both the slot 332 and the plug 341 are exposed on the fluid connector. Furthermore, after the slot 332 and the plug 341 are inserted, the two circumferential sides of the slot 332 and the two circumferential sides of the plug 341 correspond and fit together, enabling the transmission of torque between them to control the rotation of the structure.

[0054] Of course, in other embodiments, the slot 332 can also be radially disposed on the inner or outer circumferential surface of the corresponding valve cover 3. Additionally, the insert 341 can be disposed on the outer circumferential surface of the corresponding valve cover 3, or axially protrude from an axial end face of the corresponding valve cover 3; however, compared to the embodiment where the insert 341 is disposed on the outer circumferential surface of the corresponding valve cover 3, the insert 341 forms a cantilever structure when axially protruding from an axial end face of the corresponding valve cover 3. The former embodiment has better structural strength and a more compact structure after assembly with the slot 332.

[0055] Furthermore, the valve cover 3 is a one-piece molded structure to ensure structural strength. Depending on the requirements of materials and mechanical properties, the one-piece molding process can include injection molding, die forging, etc. In other embodiments, different structures on the valve cover 3 can also be fixedly connected as a single unit using welding, bolting, or other methods.

[0056] Furthermore, both valve covers 3 at the two connection ends 1 include structures partially exposed to the fluid connector. In this case, the rotation of the control structure can be achieved by directly applying torque to the exposed fluid connector on either valve cover 3 in the control structure, making operation convenient. Here, "a structure exposed to the fluid connector" mainly refers to at least a portion of the surface of the structure forming at least a portion of the outer surface of the fluid connector.

[0057] Furthermore, such as Figure 3 and Figure 4 As shown, in at least one connecting end 1, the valve cover 3 includes a valve plate 31 and an assembly ring 32 fixed to one axial side of the valve plate 31. A valve cover through hole 311 is provided on the valve plate 31, specifically penetrating the valve plate 31 axially. The assembly ring 32 is sleeved on the outside of the corresponding valve body 2, i.e., the outside of the valve body 2 in the same connecting end 1. The assembly of the valve cover 3 and the valve body 2 is completed by the sleeve of the assembly ring 32 onto the valve body 2, resulting in a simple structure and good protective effect. In embodiments where both the male end 11 and the female end 12 include two components, the assembly ring 32 and the valve plate 31, the specific shapes of the assembly ring 32 and the valve plate 31 of the male end 11 and female end 12 can be set as needed. Of course, in other embodiments, the assembly ring 32 can also be replaced by multiple circumferentially arranged claws to achieve engagement with the outer surface of the valve body 2.

[0058] For example, the valve plates 31 of the two connecting ends 1 abut against each other axially and are sealed by a sealing ring 35 to ensure that there is no leakage between the valve cover through hole 311 of the male end 11 and the corresponding valve cover through hole 311 of the female end 12. Alternatively, in other embodiments, a seal can also be achieved by the connecting ends 1 being tightly pressed together axially by end faces.

[0059] Specifically, such as Figure 4 and Figure 5 As shown, at least one valve plate 31 has an annular groove on its axial end face facing another valve plate 31 to position and install a sealing ring 35. In addition, one or more sealing rings 35 may be provided. For example, on a connecting end 1, a sealing ring 35 may be provided on the outer periphery of each valve cover through hole 311, and one or more sealing rings 35 may be provided to simultaneously encircle all valve cover through holes 311.

[0060] For example, to achieve a reliable connection between male terminal 11 and female terminal 12, such as Figure 5 and Figure 6As shown, the female valve cover 33 also includes a mating sleeve 331, which is sleeved on the outside of the male valve cover 34. At this time, the valve cover 3 of the female end 12 includes an assembly ring 32, a mating sleeve 331 and a valve plate 31 located between the two. The valve cover 3 of the male end 11 includes an assembly ring 32 and a valve plate 31, but does not have a mating sleeve 331.

[0061] In addition, such as Figure 2 As shown, a slot 332 can be opened on the female valve cover 33, specifically on the mating sleeve 331, while on the male valve cover 34, a plug 341 can be radially protruding on the outer circumferential surface of the assembly ring 32 for insertion and engagement with the slot 332, so as to realize the detachable connection of the male valve cover 34 and the female valve cover 33 and the synchronous rotation in the circumferential direction.

[0062] Furthermore, both the mating sleeve 331 and the assembly ring 32 may include at least a portion of the structure exposed to the fluid connector, thereby allowing control of either the mating sleeve 331 or the assembly ring 32 to achieve rotation of the control structure.

[0063] For example, such as Figure 3 and Figure 5 As shown, a limiting step surface 342 is also provided on the outer peripheral surface of the male valve cover 34. The limiting step surface 342 abuts against the mating sleeve 331 along the axial direction, which can improve the reliability of the connection between the valve covers 3 of the two connecting ends 1, prevent the mating sleeve 331 from swinging outside the male valve cover 34, and limit the depth of the male valve cover 34 inserted into the mating sleeve 331 to avoid over-assembly.

[0064] Furthermore, such as Figures 3 to 5 As shown, at least one connecting end 1 also includes a connecting cap 4, which is connected to the valve cover 3, for example, through a fixed connection or a rotatable connection. The valve body 2 is axially limited by the connecting cap 4 and the valve cover 3 to ensure reliable axial positioning between the valve body 2 and the valve cover 3. Specifically, the connecting cap 4 and the valve cover 3 can axially clamp at least a portion of the structure of the valve body 2. The connecting cap 4 can be detachably connected to the valve cover 3, specifically by threaded connection, bolting, or snap-fit, facilitating the assembly and disassembly of the valve body 2. Furthermore, the connecting cap 4 can be a ring-shaped structure and sleeved on the outside of the valve body 2, facilitating machining and assembly.

[0065] For example, the connecting cap 4 is fixedly connected to the valve cover 3, and to facilitate the assembly and disassembly of the connecting cap 4 and the valve cover 3, the connecting cap 4 and the valve cover 3 are threaded together. The assembly and disassembly of the two can be achieved by the helical movement of the connecting cap 4 relative to the valve cover 3, which is convenient to operate. At this time, one of the connecting cap 4 and the valve cover 3 is provided with internal threads, and the other is provided with external threads, so as to cooperate for threaded connection.

[0066] For example, the connecting cap 4 and the valve cover 3 are at least partially connected by a sleeve, and the sleeve portion is an inner cylinder portion provided on one of the connecting cap 4 and the valve cover 3, and an outer sleeve portion on the other. The outer sleeve portion is sleeved on the outside of the inner cylinder portion. The outer circumferential surface of the inner cylinder portion is provided with an external thread, and the inner circumferential surface of the outer sleeve portion is provided with an internal thread. The internal thread and the external thread are threadedly connected, thereby realizing the threaded fixed connection between the connecting cap 4 and the valve cover 3.

[0067] The positions of the inner cylinder and outer sleeve can be selected on the connecting cap 4 and valve cover 3 according to actual needs. For example... Figure 5 As shown, a portion of the connecting cap 4 and a portion of the assembly ring 32 are sleeved together, with the assembly ring 32 fitted over the outside of the connecting cap 4. In this case, the connecting cap 4 has an inner cylindrical portion with external threads, while the assembly ring 32 has an outer outer portion with internal threads. After the valve body 2 and valve cover 3 are assembled, the connecting cap 4 extends axially into the gap between the assembly ring 32 and the valve body 2, undergoing a helical motion to achieve thread locking of the internal and external threads until the connecting cap 4 is fully assembled. For example, a portion of the connecting cap 4 may be externally positioned on the assembly ring 32 and axially abut against it. At this point, the mating structure of the internal and external threads is built into the assembly ring 32, fully utilizing the internal space of the valve cover 3 to complete the assembly and fixation with the connecting cap 4, thus improving the space utilization of the valve cap.

[0068] For example, such as Figure 5 As shown, to improve the sealing between the valve body 2 and the valve cover 3, a smooth surface and an internal thread that connects to the connecting cap 4 are sequentially arranged on the inner circumferential surface of the assembly ring 32 along the axial direction away from the valve plate. A portion of the internal thread forms an outer sleeve. In this case, the smooth surface and the valve body 2 are rotatably fitted together. Specifically, in the radial direction, the mating position of the smooth surface and the internal thread on the inner circumferential surface of the assembly ring 32 can be aligned with or close to the stepped surface of the valve body 2.
