DETAILED DESCRIPTION

[0028] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. In this article, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0029] An embodiment of the present application provides a fluid control component 1 that can be used in a vehicle thermal management system, specifically in a coolant circulation system, and can perform flow isolation, conduction, and switching functions for the thermal management system.

[0030] See also Figures 1 to 7As shown, a fluid control component 1 includes a flow channel plate component 10 and a first valve core 20, the flow channel plate component 10 has at least one first accommodating chamber 102, the flow channel plate component 10 includes a cavity wall portion 111, the cavity wall portion 111 defines at least a portion of the side wall of the first accommodating chamber 102, the cavity wall portion 111 has 2N connecting ports 101, N ≥ 5 and N is a positive integer, at least a portion of the first valve core 20 is located in the first accommodating chamber 102, the first valve core 20 has N conducting channels 201, and in any working mode of the fluid control component 1, the N conducting channels 201 connect the 2N connecting ports 101 in pairs. Through the above-mentioned arrangement, it is beneficial to integrate the first valve core 20 into the flow channel plate assembly 10. Compared with setting a separate control valve structure and connecting it with the flow channel plate assembly, it is beneficial to improve the integration of the fluid control assembly 1 and reduce the occupied space of the fluid control assembly 1. The cavity wall portion 111 has 2N connecting ports 101, N ≥ 5, and the first valve core 20 has N conducting channels 201. In any working mode of the fluid control assembly 1, the N conducting channels 201 connect the 2N connecting ports 101 in pairs, which is beneficial to connect more than or equal to 10 connecting ports 101 in pairs through the first valve core 20, so as to realize multi-channel control of the fluid control assembly 1 and meet the multi-mode requirements of the thermal management system. In the embodiment of the present application, the first valve core is inserted into the flow channel plate assembly 10, so that the fluid can directly enter the conducting channel 201 after passing through the connecting port 101. Compared with the control valve and the flow channel plate assembly being separately arranged and the surface-mounted seal requiring the ports on the valve body to be bent in various directions before entering the conducting channel, the fluid control assembly 1 of the embodiment of the present application can effectively reduce the flow resistance of the system; and the embodiment of the present application can effectively utilize the space in the circumferential direction of the cavity wall portion 111, which is beneficial to reducing the mention of the fluid control assembly.

[0031] In order to improve the sealing performance of the fluid control component 1 and reduce or prevent the fluid cross-flow between the communication ports 101, Figure 4 As shown, the fluid control assembly 1 of the embodiment of the present application further includes a sealing assembly 30 , and along the radial direction of the first valve core 20 , the sealing assembly 30 is located between the outer peripheral wall of the first valve core 20 and the cavity wall portion 111 .

[0032] like Figures 1 to 8As shown, the flow channel plate assembly 10 may include a first flow channel plate 11, a second flow channel plate 12, a third flow channel plate 13 and a cover body 14, the second flow channel plate 12 is located on one side of the first flow channel plate 11 in the axial direction, the third flow channel plate 13 is located on the other side of the first flow channel plate 11 in the axial direction, the first flow channel plate 11 has a groove structure facing the second flow channel plate 12, and the first flow channel plate 11 has a groove structure facing the third flow channel plate 13, the first flow channel plate 11 and the second flow channel plate 12 are welded and sealed, for example, the first flow channel plate 11 and the second flow channel plate 12 are connected by hot plate welding. The first flow channel plate 11 and the third flow channel plate 13 are welded and sealed, so that a fluid channel 15 is formed on the flow channel plate assembly 10. At least a portion of the first accommodating chamber 102 can be located on the first flow channel plate 11, the cover body 14 is welded and sealed to the first flow channel plate 11, and the first flow channel plate 11 forms a bottom wall portion defining the first accommodating chamber 102, or the fluid control component 1 can also include a bottom cover, the bottom cover and the cover body 14 are arranged at intervals along the axial direction of the first valve core 20, and the bottom cover and the first flow channel plate 11 are welded and sealed. At this time, the cover body 14 can define the top wall of the first accommodating chamber 102, and the bottom cover can define the bottom wall of the first accommodating chamber 102, so as to isolate the first accommodating chamber 102 from the outside and reduce fluid leakage.

[0033] Furthermore, in order to improve the integration of the fluid control component 1, the fluid control component 1 also includes a fluid component 40, and the fluid component 40 includes at least one of a pump component, a valve component, and a sensor. The flow channel plate component 10 also has a second accommodating chamber 103 and a fluid channel 15. At least part of the fluid component 40 is located in the second accommodating chamber 103, and part of the fluid channel 15 connects the connecting port 101 with the fluid component 40. In some other embodiments, a blocking structure can be provided on the first flow channel plate 11, and part of the connecting port 101 can be blocked. For example, in some embodiments, the flow channel plate component 10 can have 12 connecting ports 101, and two, three, or four of the connecting ports can be blocked, and the remaining connecting ports 101 are connected to the fluid channel 15. Through the above arrangement, it is convenient to reduce the pipeline connection between different fluid components, which is conducive to improving the integration of the fluid control component 1.

[0034] Furthermore, if Figure 5As shown, the fluid control component 1 includes a circuit board 53, a driving member 51 and a conductive member 52, the conductive member 52 is located inside the flow channel plate assembly 10, and the circuit board 53 is electrically connected to the driving member 51 through the conductive member 52. Specifically, the fluid control component 1 includes a first driving member and at least one second driving member, the first driving member can drive the first valve core 20 to rotate, and the second driving member can drive the fluid component 40 to move. The first driving member and the second driving member are electrically connected to the circuit board 53 through their respective corresponding conductive members 52. The driving member 51, at least part of the flow channel plate assembly 10 and the circuit board 53 are arranged in parallel along the axial direction of the flow channel plate assembly 10. The circuit board 53 is arranged adjacent to the fluid channel 15, which is conducive to the fluid in the fluid channel 15 dissipating heat from the circuit board 53. By arranging the conductive member 52 to be located inside the flow channel plate assembly 10 and the conductive member 52 to electrically connect the circuit board 53 and the driving member 51, it is conducive to realizing control integration and further reducing the occupied space of the fluid control component 1.

[0035] In a specific implementation, the fluid component 40 includes three pump assemblies, two second valve cores, a sensor assembly and a one-way valve assembly. The fluid channel 15 connects a part of the connecting ports 101 with the pump assembly and the second valve core, and the one-way valve assembly can be embedded in the fluid channel 15 to achieve one-way conduction of the fluid channel 15. In the embodiment of the present application, the second valve core can be a three-way valve core. In other embodiments, the second valve core can also be a four-way valve core, a five-way valve core or a valve core with more than one way. The three-way valve core refers to a cavity wall that accommodates the three-way valve core, and the three-way valve core can control the flow path of the three fluid ports. Similarly, the multi-way valve core refers to a flow path that can control multiple fluid ports. The number of pump assemblies, the second valve core, the sensor assembly and the one-way valve assembly can be set according to user needs and will not be repeated.

[0036] In some embodiments, please refer to Figures 1 to 4 The sealing component 30 includes two side portions separated along its own circumferential direction, that is, in the cross section obtained by cutting the sealing component 30 along the axial direction perpendicular to the sealing component 30, the inner side and the outer side of the cross section of the sealing component 30 are both open arc-shaped structures. At this time, the two side portions of the sealing component 30 define the disconnection opening 32. Compared with setting the sealing component 30 as a closed annular structure, the sealing component 30 of the embodiment of the present application can have a larger deformation amount, which is beneficial to improve the sealing performance of the sealing component 30. Please refer to further Figure 4 In order to limit the position of the sealing assembly 30 and prevent the sealing assembly 30 from rotating and affecting the sealing effect, the flow channel plate assembly 10 also includes a limiting portion 16, the limiting portion 16 is connected to the cavity wall portion 111 and at least a part of the limiting portion 16 is located in the first accommodating cavity 102, the limiting portion 16 is located in the space defined by the two side portions of the sealing assembly 30, and the limiting portion 16 abuts against the side portion of the sealing assembly 30.

[0037] In order to achieve fluid circulation and sealing between each communication port 101, the sealing assembly 30 has a sealing port 31, and the sealing assembly 30 includes a wall portion surrounding the sealing port 31. The sealing port 31 and the disconnection port 32 are both arranged corresponding to and communicated with the corresponding communication ports 101. Figure 4 In the embodiment, the sealing component 30 has 2N-1 sealing ports 31, and the 2N-1 sealing ports 31 are arranged one-to-one and connected with the 2N-1 connecting ports 101, and the disconnection port 32 corresponds to and is connected with another connecting port. Through the above arrangement, compared with the sealing component 30 which needs to be provided with a larger size when 2N sealing ports 31 are provided on the sealing component 30, the sealing component 30 of the embodiment of the present application connects the disconnection port 32 with one of the connecting ports 101, which can help reduce the size of the sealing component 30 and the first valve core 20 while meeting the sealing requirements, thereby helping to reduce the size of the fluid control component 1 and helping to meet the requirements of a compact integrated component.

[0038] In some embodiments, the 2N communication ports 101 are located within the same axial height range of the cavity wall portion 111, and are evenly spaced along the circumferential direction of the cavity wall portion 111, and / or the central angles corresponding to the communication ports 101 located on the cavity wall portion 111 are equal. In the embodiment of the present application, the central angle corresponding to the communication port 101 refers to the angle formed by the two end points of the communication port and the center line of the first accommodating cavity 102 on the cross section obtained by cutting the flow channel plate assembly 10 perpendicular to the axial direction of the flow channel plate assembly 10 and through the center of the communication port. Through the above arrangement, it is convenient to simplify the structure of the flow channel plate assembly 10, and setting the communication ports 101 within the same height range of the cavity wall portion 111 is conducive to reducing the axial height of the flow channel plate assembly 10; and for the first valve core 20, it is conducive to the same conduction channel 201 to conduct at least two communication ports 101 at multiple rotation positions, which is convenient to simplify the structure of the first valve core 20. It should be noted that the 2N connecting ports 101 being located within the same axial height range of the cavity wall portion 111 means that the center lines of the 2N connecting ports 101 are located at the same axial height of the cavity wall portion 111, or the center lines of the 2N connecting ports 101 are located at adjacent axial heights of the cavity wall portion 111, as long as the conducting channel 201 of the first valve core can connect the connecting ports 101 in pairs.

[0039] Further, in order to realize that N conductive channels 201 connect 2N communication ports 101 in pairs, the conductive channel 201 includes a first channel 21, and the first channel 21 can connect at least two adjacent communication ports 101. And / or, the conductive channel 201 also includes a second channel 22, and the second channel 22 can connect non-adjacent communication ports 101. Figure 4As shown, the first channel 21 can be a groove structure extending from the outer wall of the first valve core 20 to the interior of the first valve core 20, and the second channel 22 has two conducting ports on the outer wall of the first valve core, and the spacing angle of the two conducting ports along the circumferential direction of the first valve core 20 is greater than the angle between the two adjacent connecting ports 101. For example, the spacing angle of the two conducting ports along the circumferential direction of the first valve core 20 can be 2 times, 3 times, 4 times or more times the angle between the two adjacent connecting ports 101, which is conducive to connecting two non-adjacent connecting ports 101.

The conduction channel 201 includes a first channel 21 and a second channel 22. Along the radial direction of the first valve core 20, a portion of the first channel 21 is closer to the outer edge of the first valve core 20 than a portion of the second channel 22. The partition plate 23 is located between the first channel 21 and the second channel 22. In the first valve core 20, the first channel 21 and the second channel 22 are fluidically isolated. Through the above arrangement, it is convenient to isolate the fluids of the conduction channels 201 in the first valve core 20, realize the switching between the various flow paths, and prevent the flow between the various flow paths.

The two second channels 22 are arranged adjacent to each other, wherein a portion of the first channels 21 are located on one side of one of the second channels 22, and the remaining number of the first channels 21 are located on the other side of the other second channel 22, or as Fig.15 As shown, parts of the two second channels 22 are arranged adjacent to each other. In this case, the same partition 23 can separate parts of the two second channels 22 , and at least one first channel 21 is arranged adjacent to both second channels 22 .
