[0039] It should be noted that the fluid control component 1 can be switched between the above-mentioned working modes by rotating the valve core 20. Furthermore, other working modes can be realized by rotating the valve core 20, which will not be described in detail. Through the above-mentioned settings, the fluid control component provided in the embodiment of the present application can realize multi-channel control. When the fluid control component is applied to the thermal management system 1, it is convenient to realize various thermal management requirements of the thermal management system by rotating the valve core.

[0040] In order to realize the above working mode of the fluid control component 1, the communication port group 120 of the side wall portion 111 includes a first communication port group 121 and a second communication port group 122. The first communication port group 121 includes the above-mentioned first port P1, second port P2, third port P3, fourth port P4 and fifth port P5, and the first port P1, second port P2, third port P3, fourth port P4 and fifth port P5 are arranged in sequence along the circumferential direction of the side wall portion 111, the sixth port P6, seventh port P7, eighth port P8, ninth port P9 and tenth port P10 are arranged in sequence along the circumferential direction of the side wall portion 111 and are arranged to form the second communication port group 122, the first port P1 and the sixth port P6 are arranged in the axial direction of the side wall portion 111, and the second port P2 and the seventh port P7 are arranged in the axial direction of the side wall portion 111. At this time, Figure 1 As shown, the communication ports 102 are arranged in two layers along the axial direction of the side wall portion 111, and the communication ports 1021 are arranged in five rows along the circumferential direction of the side wall portion 111. Through the above arrangement, on the one hand, the arrangement of the communication ports 102 and the manufacturing difficulty of the housing assembly 10 can be simplified, and on the other hand, the communication ports 102 can be connected in multiple modes through the transverse guide cavity 21 and the axial guide cavity 22, which is conducive to simplifying the structure of the valve core 20.

[0041] Please read further Figures 4 to 6In some embodiments, the valve core 20 may include at least four axial conduction chambers 22 and at least two transverse conduction chambers 21, wherein the two transverse conduction chambers 21 are arranged along the axial direction of the valve core 20, and the at least four axial conduction chambers 22 are arranged along the circumferential direction of the valve core 20. Specifically, Figure 4 and Figure 5 As shown, the valve core 20 may include four axial conduction chambers 22 and two transverse conduction chambers 21 . In this case, the valve core 20 may realize flow path control among ten communication ports 102 .

[0042] Further, in some embodiments, the valve core 20 includes a first end plate portion 231, a second end plate portion 232, a first partition portion 233, and a second partition portion 234. The first end plate portion 231 and the second end plate portion 232 are arranged at intervals along the axial direction of the valve core 20. The first partition portion 233 is connected between the first end plate portion 231 and the second end plate portion 232. The second partition portion 234 is located between the first end plate portion 231 and the second end plate portion 232 along the axial direction of the valve core 20, and the second partition portion 234 is connected between two adjacent first partition portions 233. The first partition portion 233 defines a part of the wall of the axial conduction cavity 22, and the second partition portion 234 defines a part of the wall of the transverse conduction cavity 21. Through the above arrangement, it is convenient to set the axial conduction cavity 22 and the transverse conduction cavity 21 isolated from each other on the valve core 20, so as to reduce or prevent the cross-flow between fluids.

The first end plate portion 231, the second end plate portion 232, the first partition portion 233 and the second partition portion 234 can all abut against the sealing component, thereby further reducing or preventing fluid cross-flow between the connecting ports 102, thereby improving the sealing performance of the fluid control component 1.

[0044] Optionally, the valve core 20 may further include a transmission part 25, and the fluid control assembly may further include a sealing ring 32.

[0045] When the fluid control assembly 1 is applied to the thermal management system 2, the fluid flows in the thermal management system 2 to exchange heat with the heat exchange element. When the fluid flows in the fluid control assembly 1, in order to reduce the heat exchange between the fluids, in some embodiments, the valve core 20 also has a heat insulation cavity 24, and the heat insulation cavity 24 is fluidically isolated from the transverse conduction cavity 21 and the axial conduction cavity 22.

Through the above arrangement, it is convenient to improve the heat insulation effect of the fluid control assembly 1.

[0046] In some embodiments, the valve core 20 further includes a connecting portion 235, which is connected to both the first end plate portion 231 and the second end plate portion 232. At least a portion of the first partition portion 233 and at least a portion of the second partition portion 234 are both located radially outside the connecting portion 235 and are both connected to the connecting portion 235. Along the radial direction of the valve core 20, the heat-insulating cavity 24 extends from the side close to the outer periphery of the valve core 20 to the connecting portion 235. The provision of the connecting portion 235 is conducive to improving the structural strength of the valve core 20, and by extending the heat-insulating cavity 24 to the connecting portion 235, it is conducive to increasing the heat-insulating area between adjacent conducting cavities, thereby improving the heat-insulating effect of the fluid control assembly 1.

[0047] In specific implementation, Figure 4 and Figure 5 As shown, the heat-insulating cavity 24 is located in the first partition 233, and along the axial direction of the valve core 20, the heat-insulating cavity 24 runs through the valve core. Along the projection perpendicular to the axial direction of the valve core 20, the first partition 233 has a first surface, a second surface, and an abutting surface connected between the first surface and the second surface, the abutting surface defines the outer peripheral surface of the valve core 20, and the abutting surface is arranged in abutment with the sealing component 31, the first surface defines a partial wall surface of one of the conduction cavities, and the second surface defines a partial wall surface of the other conduction cavity, wherein the first surface and / or the second surface can be in arc transition with the outer peripheral surface of the connecting portion 235, for example, the first surface and / or the second surface can be arranged tangent to the outer peripheral surface of the connecting portion 235, which is conducive to reducing the flow resistance of the fluid passing through the valve core 20.

[0048] To further improve the structural strength of the valve core 20, the valve core 20 includes a first rib 151, which is located inside the connecting portion 235 and connected to the connecting portion 235. And / or, the valve core 20 also includes a second rib 152, which is connected to the second partition 234, so as to increase the structural strength of the second partition 234.

[0049] In order to further reduce the thermal interaction between the fluids between the transverse conducting cavities 21, in some embodiments, the second partition 234 may also be provided with an insulating cavity. Specifically, at least two partition plates may be provided between adjacent transverse conducting cavities 21, and at least two partition plates may be provided at intervals along the axial direction of the valve core 20, wherein one partition plate defines a portion of the wall portion of one of the transverse conducting cavities 21, and the other partition plate defines a portion of the wall portion of the other transverse conducting cavity 21.
