[0029] In this article, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0030] For ease of understanding, the following description will be combined with the integrated components, valve devices and their seals, and the beneficial effects will not be repeated.

[0031] Valve devices can be applied to thermal management systems, such as vehicle thermal management systems, including those for new energy vehicles.

[0032] The thermal management system includes integrated components, which include valve devices that can distribute the flow of coolant (such as water).

[0033] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the integrated component provided in this application; Figure 2 for Figure 1 The diagram shows an exploded view of the integrated components.

[0034] The integrated components provided in this implementation plan include a flow channel plate 01 and a valve device. The flow channel plate 01 may have a number of flow channels 011, and the valve device is installed on the flow channel plate 01.

[0035] As one implementation method, please refer to Figures 1 to 7 As shown, the integrated assembly includes a flow channel plate 01 and a valve device. The valve device includes a valve body 10, a valve core component 20, and a seal 30. The seal 30 includes two or more sub-seal portions 31. Each sub-seal portion 31 includes a support member 311 and a sealing body 312. The sealing body 312 is fixedly connected to or limited by the support member 311. The support member 311 has a communication port 3111.

[0036] The sealing body 312 includes a first sealing body 3121 and a second sealing body 3122. The first sealing body 3121 is located on the outer periphery of the support member 311 and surrounds the communication port 3111.

At least a portion of the valve core component 20 is located in the receiving cavity 11. The valve core component 20 has a flow channel 23 that can communicate with the interface 12.

[0037] The sealing element 30 is fixedly connected to the valve body 10, the connecting port 3111 is connected to the interface 12, and the first sealing body 3121 surrounds the interface 12. Along the radial direction of the valve device, the first sealing body 3121 abuts against the valve body 10 and the support 311. The outer peripheral wall of the valve core component 20 abuts against the second sealing body 3122. The valve body 10 is fixedly connected to the flow channel plate 01, or the valve body 10 is formed on the flow channel plate 01. The flow channel plate 01 includes a flow channel 011 that communicates with the interface 12.

[0038] The integrated component provided in this application includes a valve device, which includes a seal 30. The seal 30 includes two or more sub-seal portions 31, each of which is arranged circumferentially along the valve device. Adjacent sub-seal portions 31 are connected in a limiting manner. In this way, the number of sub-seal portions 31 can be flexibly adjusted according to the application scenario, so that the seal 30 has versatility and can meet different application requirements.

[0039] In this embodiment, the valve device includes a valve body 10 and a valve core component 20. The valve body 10 can be fixedly connected to the flow channel plate 01, for example, by welding or screwing. The valve body 10 can also be integrally formed with the flow channel plate 01, that is, the valve body 10 is directly formed on the flow channel plate 01, or the valve body 10 is directly machined on the flow channel plate 01.

[0040] In one implementation, the valve device of this application includes a valve body 10, a valve core component 20, and a sealing element 30. The sealing element 30 includes two or more sub-sealing parts 31. Each sub-sealing part 31 includes a support member 311 and a sealing body 312. The sealing body 312 is fixedly connected to or limitedly connected to the support member 311. The support member 311 has a communication port 3111.

[0041] The sealing body 312 includes a first sealing body 3121 and a second sealing body 3122. The first sealing body 3121 is located on the outer periphery of the support member 311 and surrounds the communication port 3111. The second sealing body 3122 is located on the inner periphery of the support member 311 and surrounds the communication port 3111. Each sub-sealing part 31 is arranged circumferentially along the valve device. Adjacent sub-sealing parts 31 are limitedly connected. The valve body 10 has a receiving cavity 11 and an interface 12. At least a portion of the valve core component 20 is located in the receiving cavity 11. The valve core component 20 has a flow channel 23 that can communicate with the interface 12.

[0042] The sealing element 30 is fixedly connected to the valve body 10, and the connecting port 3111 communicates with the interface 12. The first sealing body 3121 surrounds the interface 12. Along the radial direction of the valve device, the first sealing body 3121 abuts against the valve body 10 and the support member 311, and the outer peripheral wall of the valve core component 20 abuts against the second sealing body 3122. The sealing element 30 provided in this application is used in a valve device, which can be used as an integrated component of a thermal management system. The sealing element 30 includes two or more sub-sealing parts 31, each sub-sealing part 31 is arranged circumferentially along the valve device, and adjacent two sub-sealing parts 31 are limited and connected. In this way, the number of sub-sealing parts 31 can be flexibly adjusted according to the application scenario, so that the sealing element 30 has versatility and can meet different application requirements.

[0043] The valve body 10 has a receiving cavity 11 and an interface 12. At least two interfaces 12 may be provided, and each interface 12 is arranged at intervals along the peripheral wall of the valve body 10. The flow channel 011 of the flow channel plate 01 is connected to the interface 12.

[0044] At least a portion of the valve core component 20 is located in the receiving cavity 11 of the valve body 10, and the valve core component 20 has a flow passage 23.

[0045] like Figure 2 As shown, the axial direction of the valve device is indicated by H. The valve body 10 of the valve device has a generally closed ring structure, and the axial direction H of the valve device is also the axial direction of the valve body 10. The central axis of the valve core component 20 is indicated by S, and the central axis S of the valve core component 20 is parallel to the axial direction H of the valve device. Typically, the central axis of the valve body 10 coincides with the central axis of the valve core component 20. The radial direction of the valve device refers to the direction perpendicular to the central axis S in a plane perpendicular to the central axis S. The directional terms "outer" and "inner" used below refer to the side relatively far from the central axis S, respectively. The use of these directional terms does not constitute a limitation on the scope of protection.

[0046] The valve core component 20 can rotate relative to the valve body 10 around its central axis S. Through this rotation, the flow channel 23 of the valve core component 20 connects to the two ports 12 of the valve body 10, thereby connecting the two flow channels 011 of the flow channel plate 01, which are respectively connected to the two ports 12. When the valve core component 20 rotates to different operating positions, the two ports 12 connected to its flow channel 23 change, thus switching the direction of fluid flow through the rotation of the valve core component 20.

[0047] In a thermal management system, the operating position of the valve device can be switched as needed to change the direction of fluid flow, allowing the fluid to flow through different flow channels 011 to the components that require thermal management.

[0048] In applications, the number of ports 12 on the valve body 10 and the number of flow channels 23 on the valve core component 20 can be determined according to the requirements of the thermal management system. The number of ports 12 on the valve body 10 can also be increased to accommodate different thermal management systems. In different thermal management system applications, the ports 12 to be used are selected as needed, and the remaining unused ports 12 can be blocked with plugs or other components.

[0049] In the illustrated embodiment, the valve core component 20 includes a first valve core 21 and a second valve core 22. The first valve core 21 is generally cylindrical in shape, and a flow channel 23 is disposed on the first valve core 21. The first valve core 21 can rotate relative to the valve body 10 around its central axis S. The second valve core 22 is coaxially disposed with the first valve core 21. Under the driving action of a driving component (not shown in the figure), the second valve core 22 can drive the first valve core 21 to rotate together around its central axis S. The second valve core 22 can also rotate relative to the first valve core 21. In application, the second valve core 22 can drive the first valve core 21 to rotate to a working mode. In this working mode, the flow channel 23 of the second valve core 22 can connect to the two ports 12 of the valve body 10. In this working mode, the second valve core 22 can rotate relative to the first valve core 21. The second valve core 22 is provided with a valve plate that can be inserted into the first valve core 21. When the second valve core 22 rotates, the valve plate can change the flow area of ​​the flow channel 23, thereby regulating the flow rate of the flow channel 23.

[0050] In other embodiments, the valve core component 20 may only have a first valve core 21, and the driving component directly drives the first valve core 21 to rotate relative to the valve body 10 to switch the working mode. In this case, the valve device does not have the function of regulating the flow of the flow channel 23. Of course, the flow of the flow channel 23 can also be regulated by installing an additional proportional regulating valve.

[0051] The valve device may also include a cover plate 40 and a fixing plate 50. One end of the second valve core 22 can pass through the cover plate 40 and the fixing plate 50 to be connected to the drive component. The cover plate 40 can be circumferentially limited to the first valve core 21. The fixing plate 50 can be fixed relative to the flow channel plate 01 to facilitate the installation or support of the drive component.

[0052] The valve assembly also includes a seal 30, which is fixedly disposed on the inner circumferential side of the valve body 10. The seal 30 is located between the inner circumferential wall of the valve body 10 and the outer circumferential wall of the valve core component 20 to reduce internal leakage of the valve assembly during operation. Specifically, the seal 30 is located between the inner circumferential wall of the valve body 10 and the outer circumferential wall of the first valve core 21.

[0053] Please refer to this as well. Figures 3 to 6 , Figure 3 for Figure 2 Schematic diagram of the middle sealing component; Figure 4 for Figure 3 A partially exploded view of the seal shown. Figure 5 for Figure 4 A schematic diagram of the neutron sealing section from one perspective; Figure 6 for Figure 4 A schematic diagram of the neutron sealing section from another perspective.

[0054] In this embodiment, the sealing element 30 includes at least one sub-sealing part 31, the sub-sealing part 31 includes a support member 311 and a sealing body 312, and the sealing body 312 is fixedly connected to or limited to the support member 311.

[0055] The support member 311 has a communication port 3111. After the seal member 30 is installed in the valve device, the communication port 3111 of the support member 311 is connected to the interface 12 of the valve body 10, so that after the valve core component 20 is rotated to the corresponding working position, the flow channel 23 can be connected to the interface 12 through the communication port 3111.

[0056] The sealing body 312 includes a first sealing body 3121 and a second sealing body 3122. The first sealing body 3121 is located on the outer periphery of the support member 311 and surrounds the communication port 3111. The second sealing body 3122 is located on the inner periphery of the support member 311 and surrounds the communication port 3111. In the valve device, the outer periphery of the support member 311 faces the valve body 10, and the inner periphery of the support member 311 faces the valve core component 20 or faces away from the valve body 10.

[0057] In application, the sub-sealing portion 31 of the seal 30 is fixedly connected to the inner circumferential side of the valve body 10, and the communication port 3111 of the sub-sealing portion 31 communicates with the interface 12 of the valve body 10. The first sealing body portion 3121 of the sub-sealing portion 31 surrounds the interface 12. Along the radial direction of the valve device, the first sealing body portion 3121 abuts against the valve body 10 and the support member 311, and the second sealing body portion 3122 is clearance-fitted or abutted against the outer circumferential wall of the valve core component 20. Specifically, the second sealing body portion 3122 is clearance-fitted or abutted against the outer circumferential wall of the first valve core 21.

[0058] When the second sealing body 3122 is in clearance fit with the outer peripheral wall of the first valve core 21, fluid pressure can be used to push the second sealing body 3122 against the outer peripheral wall of the first valve core 21, so that the second sealing body 3122 is tightly attached to the outer peripheral wall of the first valve core 21, achieving a sealing effect. When the second sealing body 3122 is in contact with the outer peripheral wall of the first valve core 21, a seal is directly formed between the two.

[0059] In some application scenarios, the number of sub-seal portions 31 of the seal 30 can be set according to the number of interfaces 12 of the valve device in use in the thermal management system application. In other words, if the valve body 10 has three interfaces 12 in use in the application of the valve device, then the seal 30 can be provided with three sub-seal portions 31, one sub-seal portion 31 at each interface 12.

[0060] In other application scenarios, the sub-seal portion 31 of the seal 30 can also be set according to the number of interfaces 12 of the valve body 10 of the valve device. That is, a sub-seal portion 31 is set for each interface 12 of the valve body 10, without having to consider the number of interfaces 12 actually used in the valve body 10. In this way, the valve device can be adapted to a wider range, and no additional assembly is required when matching different thermal management systems.

[0061] The sealing element 30 provided in this embodiment has a split structure and is provided with at least one sub-sealing part 31. The sub-sealing part 31 has a simple structure. It is convenient to provide the first sealing main body 3121 on the outer periphery of the support member 311 and the second sealing main body 3122 on the inner periphery of the support member 311. The process difficulty is low and the processing difficulty can be reduced. At the same time, it is easy to process the first sealing main body 3121 and the second sealing main body 3122 with different structural designs to meet different application requirements.

[0062] In some embodiments, the sealing body 312 of the sub-sealing part 31 is made of rubber, and the sealing body 312 can be fixed to the support member 311 through a vulcanization process. In this way, the first sealing body 3121 and the second sealing body 3122 can be formed in one step when the sub-sealing part 31 is processed, which simplifies the processing steps and makes it easier to reduce the processing difficulty.

[0063] In other embodiments, the sealing body 312 can also be molded separately and then connected to the support member 311. The first sealing body 3121 and the second sealing body 3122 of the sealing body 312 can be an integral structure connected to the support member 311 as a whole, or they can be separate structures connected to the support member 311 respectively.

[0064] The fixed connection between the sealing unit 312 and the support member 311 includes a non-removable connection, such as the vulcanized connection mentioned above, or it can be an adhesive connection, riveting connection, etc.

[0065] The limiting connection between the sealing unit 312 and the support member 311 includes a detachable connection, such as a snap-fit ​​connection.

[0066] In some embodiments, the support member 311 may be made of a material with a certain degree of hardness, such as nylon, so as to provide better support for the sealing body 312.

[0067] In this embodiment, the sealing element 30 includes two or more sub-sealing parts 31, each sub-sealing part 31 is arranged along the circumference of the valve device, and adjacent sub-sealing parts 31 are connected in a limiting manner.

[0068] In this way, the various sub-seal parts 31 can be connected together, making the seal 30 a single integrated structure, which facilitates the assembly of the seal 30 with the valve body 10 and the valve core component 20. At the same time, the number of sub-seal parts 31 can be adjusted according to different application requirements, thereby making the seal 30 versatile.

[0069] The structures of each sub-seal portion 31 of the seal 30 can be identical. This facilitates the standardized design of the sub-seal portions 31 and helps reduce processing difficulty and costs.

[0070] In the illustrated embodiment, the seal 30 is provided with eight sub-seal portions 31, which are connected in an annular structure along the upper limit of the circumference of the valve device. This annular structure is adapted to the receiving cavity 11 of the valve body 10.

[0071] like Figures 3 to 6 As shown, along the circumference of the valve device, the support member 311 of the sub-sealing part 31 has a first end 311A ​​and a second end 311B. The support member 311 has a limiting protrusion 3112 at the first end 311A ​​and a limiting recess 3113 at the second end 311B.

[0072] During assembly, the orientation of two adjacent sub-sealing parts 31 in the circumferential direction is the same, that is, the first end 311A ​​of one sub-sealing part 31 is limited and connected to the second end 311B of the adjacent sub-sealing part 31, and the second end 311B of one sub-sealing part 31 is limited and connected to the first end 311A ​​of the adjacent sub-sealing part 31.

[0073] Specifically, in two adjacent sub-sealing portions 31, at least a portion of the limiting protrusion 3112 of one is inserted into the limiting recess 3113 of the other.

[0074] Thus, the various sub-sealing parts 31 are sequentially connected along the circumference of the valve device to form a closed ring structure, such as... Figure 3 As shown.

[0075] In the specific implementation, the limiting protrusion 3112 of the sub-seal part 31 extends along the axial direction of the valve device, and the limiting recess 3113 also extends along the axial direction of the valve device. In this way, after the two adjacent sub-seal parts 31 are fitted together by the limiting protrusion 3112 and the limiting recess 3113, the connection between the two is highly reliable.

[0076] In some embodiments, the support member 311 includes a support body 3114, which has an arc-shaped plate structure. This facilitates connecting the sub-seal parts 31 into a ring structure, making it easy to assemble with the valve body 10.

[0077] like Figures 4 to 6 As shown, the support body 3114 has a first end face 31141 at the first end 311A ​​and a second end face 31142 at the second end 311B.

[0078] The first end face 31141 protrudes outward near the outer peripheral wall to form a limiting protrusion 3112, which can be in a cylindrical shape.

[0079] A protruding wall portion 3115 protrudes outward from the outer peripheral wall of the support body 3114 near the second end 311B. This protruding wall portion 3115 has a semi-circular annular cylindrical structure and forms a generally cylindrical through groove, which forms a limiting recess 3113. The end of the protruding wall portion 3115 away from the support body 3114 has a wall end face 31151, which is located away from the first end 311A ​​relative to the second end face 31142. An opening for the limiting recess 3113 is formed between the wall end face 31151 and the second end face 31142. During assembly, the limiting protrusion 3112 of another sub-sealing portion 31 can be inserted into the limiting recess 3113 through this opening.

[0080] The limiting protrusion 3112 is configured as a cylindrical structure, and the limiting recess 3113 is configured as a cylindrical groove structure, so that the limiting protrusion 3112 can be inserted into the limiting recess 3113.

[0081] Please refer to this as well. Figure 7 , Figure 7 for Figure 4 A magnified view of the connection point between two adjacent sub-seal parts.

[0082] In some embodiments, in two adjacent sub-sealing portions 31, the limiting protrusion 3112 of one and the limiting recess 3113 of the other are elastically press-fitted. In this way, the connection between the two adjacent sub-sealing portions 31 is more secure, the connection reliability is high, and it is not easy to loosen.

[0083] After the two sub-sealing parts 31 are engaged by the limiting protrusion 3112 and the limiting recess 3113, the limiting protrusion 3112 is inserted into the limiting recess 3113. Through the relevant structural settings, the second end face 31142 of one sub-sealing part 31 can be attached to the first end face 31141 of the other sub-sealing part 31, and the wall end face 31151 of the protruding wall part 3115 of one sub-sealing part 31 can be attached to the outer peripheral wall surface of the support member 311 of the other sub-sealing part 31.

[0084] In some embodiments, after the limiting protrusion 3112 of one of two adjacent sub-sealing portions 31 is inserted into the limiting recess 3113 of the other, the limiting protrusion 3112 can rotate relative to the limiting recess 3113, and the rotation center line of the limiting protrusion 3112 is parallel to the axial direction of the valve device. In this way, after the two adjacent sub-sealing portions 31 are connected, the relative position of the two sub-sealing portions 31 can be adjusted by rotating the limiting protrusion 3112, thereby adjusting the diameter of the formed annular sealing member 30, making the sub-sealing portion 31 versatile.

[0085] Specifically, the sub-sealing portions 31 of the seal 30 have identical structures. Based on standardized design, the sub-sealing portions 31 can be interchangeable within a certain range of the seal 30's diameter. For example, the seal 30 shown in the figure has eight sub-sealing portions 31, which are adapted to the valve body 10 shown. In other application examples, if the radial dimension of the receiving cavity 11 of the valve body 10 is relatively small, and correspondingly, the diameter of the matching seal 30 is smaller, the sub-sealing portions 31 shown can still be used to form the seal 30. For example, six or seven sub-sealing portions 31 can be connected to form another seal 30 with a smaller diameter. Of course, nine or ten sub-sealing portions 31 can also be connected to form another seal 30 with a larger diameter.

[0086] See again Figure 7 To allow the limiting protrusion 3112 at the connection point of two adjacent sub-sealing parts 31 to rotate relative to the limiting recess 3113 to adjust its position after the two parts are connected in a limiting manner, the support body 3114 of the support member 311 may have Figure 7 The first end face 31141', indicated by the dashed line, allows the sub-seal portion 31 on the right side of the figure to rotate clockwise (based on the orientation shown in the figure) to reduce the diameter of the seal 30; alternatively, the protruding wall portion 3115 of the support member 311 can have Figure 7 The wall end face 31151' is indicated by the dashed line. In this way, the sub-seal part 31 on the right side of the figure can rotate counterclockwise (based on the orientation shown in the figure) to increase the diameter of the seal 30.

[0087] Figure 7 The dotted lines in the diagram are merely illustrative. In actual applications, after the two sub-sealing parts 31 are connected in a limiting manner, when the two support members 311 are on the same circumference, a gap is formed between the opposing end faces of the two support bodies 3114, and a gap is formed between the protruding wall part 3115 and the outer peripheral wall of the support body 3114, so that the relative positions of the two sub-sealing parts 31 can be adjusted within a certain range.

[0088] In other embodiments, the seal 30 may include at least one connecting portion, and the sub-seal portions 31 and the connecting portions of the seal 30 are connected in a ring structure along the circumferential direction of the valve device. In this way, the seal 30 may only have sub-seal portions 31 matching the number of actual use interfaces 12, and these sub-seal portions 31 and the connecting portions are connected to form a ring structure to facilitate assembly with the valve body 10.

[0089] In a specific implementation, the structure of the connecting part can be similar to that of the support member 311, including an arc-shaped connecting plate. The connecting plate does not need to have a communication port 3111. The connecting plate has a connecting protrusion and a connecting recess at both ends along the circumference of the valve device. The connecting protrusion has the same structure as the limiting protrusion 3112, and the connecting recess has the same structure as the limiting recess 3113. This facilitates the upper-limit connection between the connecting part and the sub-sealing part 31 in the circumference of the valve device.

[0090] In some embodiments, the seal 30 and the valve body 10 can be fixed by injection molding. Specifically, the valve body 10 is injection molded with the annular seal 30 as an insert. This results in a better sealing effect between the seal 30 and the valve body 10.

[0091] Specifically, the valve body 10 is injection molded with at least the sealing element 30 as an insert, at least the outer peripheral wall of the support 311 and the first sealing main body 3121 are located inside the valve body 10, at least a portion of the second sealing main body 3122 constitutes the inner peripheral wall of the valve body 10, and at least a portion of the second sealing main body 3122 abuts against the outer peripheral wall of the valve core component 20.

[0092] When the seal 30 is fixed to the valve body 10 by injection molding, the support 311 of the sub-seal part 31 can be made of a high-temperature resistant material to provide support for the sealing body 312 during the injection molding process, so as to reduce the impact of the injection pressure on the sealing body 312 during the injection molding process.

[0093] In other embodiments, the seal 30 and the valve body 10 may also be fixed by welding or bonding.
