Description

Technical Field

[0001] This utility model relates to the field of fluid control, specifically to a fluid control component and thermal management system for vehicles or energy storage. Background Technology

[0002] In the automotive industry, vehicle thermal management systems require multi-channel control valves to control flow paths. The control valve includes a valve body and a valve core, with the valve core rotatably disposed within a valve cavity in the valve body to facilitate the control of the fluid by the control valve.

[0003] As the functional modes of thermal management systems increase, the valve core structure is equipped with multiple conduction cavities to meet the requirements of multi-path control functions, but the valve core structure is complex. Utility Model Content

[0004] Based on this, the technical solution of this application provides a fluid control component and a thermal management system, which facilitates the realization of multi-channel control functions and helps to simplify the valve core structure.

[0005] On one hand, this application provides a fluid control assembly, which includes a housing assembly and a valve core assembly. The housing assembly has a valve cavity and includes a sidewall portion defining a portion of the valve cavity wall. The sidewall portion has a first layer of communication ports and a second layer of communication ports arranged axially along the sidewall portion. The first layer of communication ports has a plurality of first communication ports arranged circumferentially along the sidewall portion. The second layer of communication ports has at least one second communication port. At least a portion of the valve core assembly is located in the valve cavity and the valve core assembly is rotatable. The valve core assembly includes a first layer of conductive portion and a second layer of conductive portion. The first layer of conductive portion has a plurality of first conductive cavities, each first conductive cavity having a first conductive port facing the housing assembly. At least a portion of the first conductive ports is arranged axially symmetrically. The second layer of conductive portion has a second conductive cavity. The conductive cavity communicates with a portion of the first conductive cavity; the first conductive cavity and the plurality of first connecting ports define a first layer flow path relationship, and the first layer flow path relationship is the same in at least two symmetrical working positions of the valve core assembly. In one of the at least two symmetrical working positions of the valve core assembly, the second connecting port is closed, and in the other of the at least two symmetrical working positions of the valve core assembly, the first connecting port communicates with the second connecting port through the first conductive cavity and the second conductive cavity; along the circumferential direction of the sidewall portion, at least one first connecting port is spaced apart between the circumferential regions where the first connecting port and the second connecting port are connected through the first conductive cavity and the second conductive cavity, or the circumferential regions where the first connecting port and the second connecting port are connected through the first conductive cavity and the second conductive cavity are adjacent, and the number of second connecting ports is at least two.

[0006] According to the fluid control assembly provided in this application, the side wall of the housing assembly has a first layer of connecting ports and a second layer of connecting ports. The valve core assembly includes a first layer of conductive portion and a second layer of conductive portion. The first layer of conductive portion has a first conductive cavity that can conduct the first connecting ports included in the first layer of connecting ports, so that the first conductive cavity conducts the first connecting ports to form a fluid flow path. The second layer of conductive portion has a second conductive cavity that can conduct the second connecting ports included in the second layer of connecting ports, so that the second conductive cavity conducts the second connecting ports to form a fluid flow path. The second conductive cavity communicates with a portion of the first conductive cavity. In different working positions, the second connecting ports are closed, or; by setting at least a portion of the first conductive ports to be arranged axially symmetrically, when the valve core assembly is in at least two symmetrical working positions, the first conductive cavity conducts multiple first... The first layer flow path relationship defined between the connecting ports is the same, and the connection relationship of the second connecting ports is different. That is, in one of the at least two symmetrical working positions of the valve core assembly, the second connecting port is closed. In the other of the at least two symmetrical working positions of the valve core assembly, the circumferential regions where the first connecting port and the second connecting port are connected through the first and second conductive cavities are adjacent, or the circumferential regions where the first connecting port and the second connecting port are connected through the first and second conductive cavities are spaced apart by at least one first connecting port. The rotation of the valve core can realize the simultaneous conversion of different flow paths, which can increase the multi-channel mode and realize the multi-functionality of the valve. Furthermore, by setting the axisymmetric first conductive port structure, the first layer of conductive part and the second layer of conductive part, it is beneficial to simplify the valve core structure.

[0007] On the other hand, the present application provides a thermal management system including the aforementioned fluid control components. According to the thermal management system of the present application, at least a portion of the first conductive ports of the valve core assembly are arranged axially symmetrically, such that when the valve core assembly is in at least two symmetrical working positions, the first conductive cavity connects the multiple first connecting ports in the same first layer of flow path relationship. In one of the at least two symmetrical working positions of the valve core assembly, the second connecting port is closed, which facilitates fluid flow in the first heat exchange branch and the second heat exchange branch. In the other of the at least two symmetrical working positions of the valve core assembly, the first connecting port is connected to the second connecting port through the first and second conductive cavities, allowing fluid to interact between different pipelines, thus facilitating the fulfillment of the functional requirements of the thermal management system and improving the heat exchange efficiency of the thermal management system.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0051] This application provides a fluid control component that can be used in a vehicle thermal management system, specifically in a coolant circulation system, and can perform flow path isolation, conduction, and switching functions for the thermal management system.

[0052] like Figures 1 to 7As shown, the fluid control assembly 1 implemented in this application includes a housing assembly 10, a valve core assembly 20, and a sealing assembly 30. The housing assembly 10 has a valve cavity 101. The housing assembly 10 includes a side wall portion 11, a cover portion 15, and a bottom wall portion 12. The side wall portion 11 defines a portion of the wall of the valve cavity 101. Along the axial direction of the side wall portion 11, at least a portion of the side wall portion 11 is located between the bottom wall portion 12 and the cover portion 15. The side wall portion 11, the cover portion 15, and the bottom wall portion 12 define at least a portion of the valve cavity 101. At least a number of communication ports are located on the inner surface of the side wall portion 11. The side wall portion 11 defines at least a portion of the peripheral wall of the valve cavity 101. The cover portion 15 and the bottom wall portion 12 are both sealed to the side wall portion 11. For example, one of the cover portion 15 and the bottom wall portion 12 is injection molded as an integral structure with the side wall portion 11, and the other is welded or bonded to the side wall portion 11 or sealed by a seal. At least a portion of the valve core assembly 20 is located in the valve cavity 101 and the valve core assembly 20 is rotatable within the valve cavity 101.

[0053] One of the valve core assembly and the housing assembly has a first groove 10a, and the other has a first protrusion 10b. At least a portion of the first protrusion 10b is embedded in the first groove 10a. The valve core assembly is positioned through the convex-concave mating structure, which improves the coaxiality of the valve core assembly and the side wall portion. Specifically, the valve core assembly has a hollow cylindrical portion with a first groove 10a, and the bottom wall portion 12 has a first protrusion 10b. The first protrusion fits into the first groove 10a, and the valve core assembly rotates around the first protrusion 10b.

[0054] Along the radial direction of the sidewall portion 11, at least a portion of the sealing assembly 30 is located between the sidewall portion 11 and the valve core assembly 20 for sealing the fluid control assembly 1. The sealing assembly 30 has a through-hole opposite to and communicating with the communication port to connect the corresponding communication port. In this embodiment, all of the communication ports are located in the sidewall portion 11. In some other embodiments, a portion of the communication ports may be located in the sidewall portion 11, while another portion of the communication ports may be located in the cover portion 15 and / or the bottom wall portion 12.

[0055] Optionally, to increase the structural strength of the sidewall portion 11, the wall thickness of the sidewall portion 11 can decrease along the direction from the bottom wall portion 12 to the cover portion 15. In this case, the inner wall surface of the sidewall portion 11 can be a conical surface. This facilitates demolding and increases the strength of the sidewall portion 11, mitigating the deformation caused by the compression of the sealing assembly 30, thereby improving the sealing performance of the fluid control assembly 1. And / or, the outer periphery of the sidewall portion 11 may also include a reinforcing wall portion and a connecting rib portion, with the connecting rib portion connecting the sidewall portion 11 and the reinforcing wall portion, to further improve the structural strength of the housing assembly 10.

[0056] To enable the rotation of the valve core assembly 20, the fluid control assembly 1 may optionally include a drive assembly. The drive assembly includes a drive element, which may include a motor or a combination of a motor and a transmission gear set. The drive element is connected to the valve core assembly 20 in a transmission connection, causing the drive element to drive the valve core assembly 20 to rotate. The rotation of the valve core assembly 20 establishes the connection of at least two communication ports, thereby enabling the fluid control assembly 1 to control the fluid flow path. A sealing ring 16 is used to seal the drive assembly and the valve core assembly.

[0057] In some embodiments, the fluid control component 1 may also have a port exposed on the surface of the fluid control component 1. The fluid control component 1 may also include a connector having a flow channel, one end of which communicates with a corresponding communication port, and the other end forming a port of the fluid control component 1. The connector is sealed to the housing component 10 and located on the outer periphery of the side wall portion 11. The connector may be connected to other fluid components in the thermal management system. For example, the fluid component may be a heat exchanger, a water pump, or other structure. The connector may be injection molded as an integral structure with the side wall portion 11 of the housing component 10, or welded, or sealed by a seal.

[0058] Alternatively, the fluid control assembly 1 may also include a mounting plate portion located outside the housing assembly 10 and sealed to the housing assembly 10. For example, the mounting plate portion may be injection molded integrally with the side wall portion 11 and / or the bottom wall portion 12. Optionally, the ports are located on the outer surface of the mounting plate portion and at least a portion of the ports have the same orientation. The mounting plate portion has a mounting surface that can be connected to other fluid components in the thermal management system. For example, the fluid components may be structures such as heat exchangers or water pumps.

[0059] Alternatively, in some other embodiments, the housing assembly 10 may also have an integrated flow channel that communicates with a corresponding connection port and with other fluid components, such as a pump chamber or another valve chamber. Specifically, the fluid control component may be an insert-type water valve, i.e., the housing assembly and the flow channel plate are an integral structure, the sealing assembly 30 and the valve core assembly 20 are insert-type installed, and the cover portion 15 is welded or sealed.

[0060] Further reading Figures 1 to 7 In some embodiments, the sidewall portion 11 has a first layer of communication ports 102 and a second layer of communication ports 103 arranged along the axial direction of the sidewall portion 11. The first layer of communication ports 102 has a plurality of first communication ports 13 arranged along the circumferential direction of the sidewall portion 11, and the second layer of communication ports 103 has at least one second communication port 14.

[0061] At least a portion of the valve core assembly 20 is located in the valve cavity 101, corresponding to the communication port on the side wall portion 11. The valve core assembly 20 includes a first layer of conductive portion 21 and a second layer of conductive portion 22. The first layer of conductive portion 21 has a plurality of first conductive cavities 210, and each first conductive cavity 210 has a first conductive port 213 facing the housing assembly 10. The first conductive port 213 is capable of conducting at least two first communication ports 13. At least a portion of the first conductive port 213 is arranged axially symmetrically, such as... Figure 4A As shown, in a cross-section passing through the centerline of the first guide port 213 and perpendicular to the axis of the valve core assembly 20, at least a portion of the first guide port 213 is arranged axially symmetrically. This arrangement ensures that when the valve core assembly 20 is in two axially symmetrical working positions, the first layer flow path relationship formed by the first guide port 213 and the first connecting port 13 is identical. The second layer guide portion 22 has a second guide cavity 220, which communicates with a portion of the first guide cavity 210.

[0062] In one operating mode of the fluid control component 1, a first-layer flow path relationship is defined between the first conductive cavity 210 and the plurality of first connecting ports 13, and the second connecting port 14 is closed. In another operating mode of the fluid control component 1, the first conductive cavity 210 and the plurality of first connecting ports 13 define a first-layer flow path relationship, and the second conductive cavity 220 is connected to the second connecting port 14. Along the circumferential direction of the sidewall portion, the circumferential regions where the first connecting ports 13 and the second connecting ports 14 are connected through the first conductive cavity 210 and the second conductive cavity 220 are adjacent, or at least one first connecting port 13 is spaced apart between the circumferential regions where the first connecting ports 13 and the second connecting ports 14 are connected through the first conductive cavity 210 and the second conductive cavity 220. That is, the connected first connecting ports 13 and the second connecting ports 14 are adjacent, or at least one first connecting port 13 is spaced apart between the connected first connecting ports 13 and the second connecting ports 14. That is, the side wall portion is projected along the axial direction of the valve core assembly, and there are other first communication ports adjacent to or spaced apart from the connected first and second communication ports, so as to... Figure 4B For example, along the circumferential direction of the side wall, when the second connecting port 14 (such as P10) and the first connecting port 13 (such as P1) are connected, P10 and P1 are adjacent. If P10 and P2 are connected, then P10 and P2 are separated by a first connecting port (such as P1).

[0063] With the above configuration, when the valve core assembly 20 is located in two axially symmetrical positions, the first conducting cavity 210 connects the multiple first connecting ports 13 in the same first layer flow path relationship, and the opening and closing states of the second connecting port 14 are different. Specifically, in some operating modes, the first conducting cavity 210 connects the multiple first connecting ports 13 to form a first layer flow path relationship, and the second connecting port 14 is closed. In another operating mode of the fluid control assembly, the first conducting cavity 210 connects the multiple first connecting ports 13 to form the same first layer flow path relationship, and the second conducting cavity 220 is connected to the second connecting port 14. This facilitates the connection between the first connecting ports 13 and the second connecting port 14, which is convenient for meeting the operating modes of the fluid control assembly. Furthermore, by setting the axially symmetrical first conducting port 213 structure, the first layer conducting part 21, and the second layer conducting part 22, the structure of the valve core assembly 20 is simplified.

[0064] It should be noted that the first-layer flow path relationship defined between the first conductive cavity 210 and the multiple first connecting ports 13 refers to the flow path relationship or conductive relationship formed after the first conductive cavity 210 in the first-layer conductive part 21 connects the multiple first connecting ports 13. For example, in Figure 4, there are 5 first conductive cavities 210 and 10 first connecting ports 13. The first conductive cavity 210 forms five flow paths for the first connecting ports 13. In this case, the first-layer flow path relationship defined between the first conductive cavity 210 and the multiple first connecting ports 13 refers to the above-mentioned five flow path relationships.

[0065] Refer to Figure 4A and Figure 5 , Figure 6In some embodiments, the fluid control assembly 1 has a sealing assembly 30, which has a first channel 31 and a second channel 32. The first channel 31 communicates with a first connecting port 13, and the second channel 32 communicates with a second connecting port 14. The first conductive cavity 210 includes a straight cavity 211, where the circumferential angle α1 corresponding to the first conductive port 213 is greater than or equal to the maximum circumferential angle α2 corresponding to at least two first channels 31. The circumferential angles of the first channel 31 and the second channel 32 may be the same or different. For ease of manufacturing, in one specific embodiment, the circumferential angle α3 of each first channel 31 and each second channel 32 is the same. The second conductive cavity 220 has a second conductive port 223 facing the housing assembly 10, where the first circumferential angle β1 corresponding to at least one second conductive port 223 is greater than or equal to the maximum circumferential angle α2 corresponding to at least two first channels 31. With the above configuration, the straight-through cavity 211 can be connected to at least two first connecting ports 13 through at least two first channels 31. Furthermore, a portion of the straight-through cavity 211 and the second connecting cavity 220 are arranged axially along the valve core assembly 20, and a portion of the straight-through cavity 211 is connected to the second connecting cavity 220, which simplifies the structure of the valve core assembly 20. The second connecting cavity 220 can be connected to at least one second connecting port 14, facilitating the connection of the first connecting ports 13 and 14 through the straight-through cavity 211 and the second connecting cavity 220. By connecting the straight cavity 211 and the second conductive cavity 220 with a first circumferential angle β1 corresponding to the second conductive port 223 being greater than or equal to at least two maximum circumferential angles α2 corresponding to the first channel 31, the maximum circumferential angles of the connected first conductive cavity 210 and the second conductive cavity 220 are greater than or equal to at least two maximum circumferential angles α2 corresponding to the first channel 31. This allows the connected first connecting port 13 and the second connecting port 14 to be adjacent, or the connected first connecting port 13 and the second connecting port 14 to be spaced apart by at least one first connecting port 13. Alternatively, at least one circumferential angle α1 corresponding to the first conductive port 213 is greater than or equal to at least one second circumferential angle β2 corresponding to the second conductive port 223, the second circumferential angle β2 is greater than or equal to a maximum circumferential angle α3 corresponding to a second channel 32, and the circumferential angle of the second channel 32 is less than or equal to the circumferential angle of the first channel 31. It is understood that, in this paper, the circumferential angle α1 corresponding to the first through port 213 of the through cavity 211 refers to the angle formed by the contact position between the wall of the through cavity 211 and the sealing assembly 30 and the centerline of the valve core assembly 20. The first circumferential angle β1 corresponding to the second through port 223 refers to the angle formed by the contact position between the wall of the second through port and the sealing assembly 30 and the centerline of the valve core assembly 20.

[0066] In a specific implementation, as shown in Figures 4 to 8, the circumferential angle α1 corresponding to the first connecting port 213 of the straight cavity 211 is greater than or equal to twice the first circumferential angle β1 corresponding to the second connecting port 223 of the second connecting cavity 220. Furthermore, one side of the wall of the straight cavity 211 is coplanar with one side of the wall of the second connecting cavity 220. Through this arrangement, when the straight cavity 211 is directly opposite to at least two first connecting ports 13, the second connecting cavity 220 can be directly opposite to the second connecting port, which facilitates the connection between the first connecting ports 13 and the second connecting port 14 and reduces fluid flow resistance. In another embodiment, the circumferential angle α1 corresponding to the first through port 213 of the straight cavity 211 is equal to the second circumferential angle β2 corresponding to the second through port 223 of the second through cavity 220. The second through cavity 220 further includes a second connecting sub-cavity 220b. The second partition plate 235 and the first partition plate 234 defining the second connecting sub-cavity 220b are arranged at intervals along the circumferential direction of the valve core assembly 20. The circumferential angle corresponding to the cavity wall of the second connecting sub-cavity 220b is equal to the circumferential angle corresponding to the cavity wall of the first through cavity 210. The projection of the cavity wall of the second connecting sub-cavity 220b and the projection of the wall portion of the first through port 213 partially overlap. This facilitates the connection between the spaced-apart first and second connecting ports.

[0067] To ensure that the second connector 14 is closed in some modes, as shown in Figures 4 to 5. Figure 7 As shown, in some embodiments, at least a portion of the first through port 213 is arranged axially symmetrically about the radial direction of the valve core assembly 20. The second through cavity 220 has a second through port 223 facing the housing assembly 10. The second through portion 22 also has an isolation portion 221, at least a portion of which is arranged radially along the valve core assembly 20 with the wall defining the second through port 223. The isolation portion 221 is fluidly isolated from both the first through cavity 210 and the second through cavity 220. This arrangement facilitates the closure of the second communication port 14 by the isolation portion 221 in some operating positions of the valve core assembly 20. In this document, fluid isolation between the isolation portion 221 and the first through cavity 210 and the second through cavity 220 means that there is no communication between the isolation portion 221 and the first through cavity 210, and between the isolation portion 221 and the second through cavity 220 in the valve core assembly 20, and there is no fluid interaction between the isolation portion 221 and the first through cavity 210.

[0068] Furthermore, in some embodiments, the first conducting cavity 210 further includes a through cavity 212. Along the radial direction of the valve core assembly 20, the straight cavity 211 is closer to the outer peripheral edge of the valve core assembly 20 than the through cavity 212. Along the circumferential direction of the valve core assembly 20, the through cavity 212 has at least two first conducting ports 213 facing the housing assembly 10. Along the circumferential direction of the valve core assembly 20, there is a first conducting port 213 of the straight cavity 211 facing the housing assembly 10 between the first conducting ports 213 of the through cavity 212 facing the housing assembly 10. The through cavity 212 can connect at least two non-adjacent first connecting ports 13. With the above configuration, it is convenient to realize the multi-mode requirements of the fluid control component 1.

[0069] In this embodiment, the valve core assembly 20 further includes a top plate 231, an intermediate plate 232, a bottom plate 233, a first partition plate 234, and a second partition plate 235. The top plate 231, intermediate plate 232, bottom plate 233, first partition plate 234, and second partition plate 235 can all abut against the inner surface of the sealing assembly 30. The top plate 231, intermediate plate 232, and bottom plate 233 are arranged axially along the valve core assembly 20. The first partition plate 234 connects the top plate 231 and the intermediate plate 232, and the second partition plate 235 connects the intermediate plate 232 and the bottom plate 233. The first conductive cavity 210 is located between the top plate 231 and the intermediate plate 232, and the first partition plate 234 defines a portion of the wall of the first conductive cavity 210. This arrangement facilitates the formation of independent conductive cavities within the valve core assembly 20.

[0070] like Figure 7 As shown, the second conductive cavity 220 is located between the intermediate plate 232 and the bottom plate 233; the second conductive cavity 220 includes a first connecting sub-cavity 220a, and the second partition plate 235 and the first partition plate 234 that partially define the first connecting sub-cavity 220a are connected, and the circumferential angle corresponding to the cavity wall of the first connecting sub-cavity 220a is smaller than the circumferential angle corresponding to the cavity wall of the first conductive cavity 210. That is, the first conductive cavity can connect two adjacent first connecting ports, and the second connecting port can connect a second conductive cavity. The second conductive cavity and the first conductive cavity are connected. In this way, the valve core assembly can provide a structural basis for realizing the connection between adjacent first connecting ports and second connecting ports.

[0071] Continue to refer to Figure 7The second conductive cavity 220 further includes a second connecting sub-cavity 220b. The circumferential angle corresponding to the cavity wall of the second connecting sub-cavity 220b is equal to the circumferential angle corresponding to the cavity wall of the first conductive cavity 210. That is, the first conductive cavity can connect two adjacent first connecting ports, and the second connecting port can connect one second conductive cavity. The second conductive cavity and the first conductive cavity are connected. The projection of the wall portion of the first conductive port and the projection of the wall portion of the second conductive port are partially overlapped along the axial direction of the valve core assembly, as shown by the arrow, to realize the connection between the spaced first connecting ports and the second connecting ports. Along the axial direction of the valve core assembly, the second partition plate 235 and the first partition plate 234 of the second connecting sub-cavity 220b are arranged at intervals along the circumferential direction of the valve core assembly 20. The first partition plate and the second partition plate that defines the cavity wall of the second connecting sub-cavity 220b are not coplanar.

[0072] like Figure 3 As shown, in one specific embodiment, the bottom plate 233 is recessed towards the top plate 231, and the radial dimension of the bottom plate 233 gradually decreases along the direction from the bottom wall portion 12 to the cover portion 15. This helps to maintain the uniformity of the wall thickness of the valve core assembly.

[0073] like Figure 5 As shown, to reduce the weight of the valve core assembly 20 and facilitate its injection molding, in some embodiments, the isolation portion 221 of the second conductive portion 22 further includes a weight-reducing cavity 222, which penetrates the circumferential sidewall of the valve core assembly 20. The weight-reducing cavity 222 is located between the intermediate plate 232 and the bottom plate 233. One side of the second partition plate 235 defines a portion of the wall of the second conductive cavity 220, and the other side of the second partition plate 235 defines a portion of the wall of the weight-reducing cavity 222. This arrangement facilitates both weight reduction and uniform wall thickness of the valve core assembly 20, thus enabling injection molding.

[0074] The first conductive cavity 210 is located between the top plate 231 and the middle plate 232, and the second conductive cavity 220 and the weight reduction cavity 222 are located between the middle plate 232 and the bottom plate 233.

[0075] Furthermore, such as Figure 5 As shown, the second-layer conductive section 22 has at least four second conductive cavities 220, which enable the valve core assembly 20 to connect the second conductive cavity 220 with the second communication port 14 when rotated to at least four working positions.

[0076] In some embodiments, the through cavity 211 includes a first sub-cavity 214, a second sub-cavity 215, a third sub-cavity 216, and a fourth sub-cavity 217. The number of through cavities 212 is at least one. Along the radial direction of the valve core assembly 20, the first sub-cavity 214 and the second sub-cavity 215 are both located on one side of the through cavity 212, and the third sub-cavity 216 and the fourth sub-cavity 217 are both located on the other side of the through cavity 212. The first sub-cavities 214 and the second sub-cavities 215 are arranged along the circumferential direction of the valve core assembly 20, and the third sub-cavities 216 and the fourth sub-cavities 217 are also arranged along the circumferential direction of the valve core assembly 20. The number of first connecting sub-cavities 220b is three, and the number of second connecting sub-cavities 220b is one. This arrangement facilitates the fluid control assembly 1 to achieve multi-path control functionality.

[0077] like Figure 4A and Figure 5 As shown, the number of through cavities 211 can be four. In other embodiments, the number of through cavities 211 can be six, two, eight, or more. The through cavity 211 can be a groove structure extending from the outer peripheral edge of the valve core assembly 20 into the interior of the valve core assembly 20, in which case the through cavity 211 forms a first through port. In other embodiments, the through cavity 211 can be a curved through channel with first through ports at both ends. This application does not limit the specific structure of the through cavity 211, as long as the first through port of the through cavity 211, which is directly opposite the first connecting port 13, is at least partially axially symmetrical.

[0078] like Figure 1 and Figure 4B As shown, in some embodiments, there are two second guide ports 223, which are arranged along the axial direction of one of the first guide ports 213 on the side wall portion 11. By increasing the number of second guide ports 223, the probability of the second communication port connecting during the rotation of the valve core assembly 20 increases, thereby increasing the number of passage modes.

[0079] In some embodiments, the first communication port 13 includes a first port P1, a second port P2, a third port P3, a fourth port P4, a fifth port P5, a sixth port P6, a seventh port P7, an eighth port P8, a first port PA1, and a second port PA2 arranged along the circumferential direction of the sidewall portion 11, wherein the first port P1 and the third port P3 are symmetrical, the second port P2 and the fourth port P4 are symmetrical, the fifth port P5 and the sixth port P6 are symmetrical, the seventh port P7 and the eighth port P8 are symmetrical, and the first port PA1 and the second port PA2 are symmetrical. The number of second communication ports 14 can be two. The second communication port 14 includes a ninth port P9 and a tenth port P10 arranged along the circumferential direction of the sidewall portion 11. The tenth port P10 and the first port PA1 are arranged along the axial direction of the sidewall portion 11, and the ninth port P9 and the seventh port P7 are arranged along the axial direction of the sidewall portion 11. In this case, the fluid control component 1 of this application embodiment can be a twelve-way valve or a part of the fluid control component 1 can be a twelve-way valve. By connecting two symmetrically arranged first connecting ports through an external flow channel, for example, by connecting port I PA1 and port II PA2 through an external pipeline, a double-layer ten-way valve mode can be realized.

[0106] The above settings facilitate the control of the flow path by the fluid control component 1. When the fluid control component 1 is applied to the thermal management system, it enables multiple switching modes of the thermal management system. In the above working modes of the fluid control component 1, the first-layer flow path relationship formed by the first-layer connecting port is the same in the first working mode and the fourth working mode, and the connection relationship of the second connecting port 14 is different. The rotation angle of the valve core assembly 20 from the first working position to the fourth working position is 180 degrees.

In the second working mode and the fifth working mode, the first-layer flow path relationship formed by the first-layer connecting port is the same, and the connection relationship of the second connecting port 14 is different. The rotation angle of the valve core assembly 20 from the second working position to the fifth working position is 180 degrees. At this time, the second working position and the fifth working position are two symmetrical working positions. In both the third and sixth operating modes, the first-layer flow path relationships formed by the first-layer connecting ports are the same, while the connection relationships of the second connecting ports 14 are different. The valve core assembly 20 rotates 180 degrees when switching from the third to the sixth operating position, making the third and sixth operating positions symmetrical. With this configuration, when the fluid control assembly is applied to a thermal management system, it is convenient to close or open the second connecting port 14 as needed.

[0107] On the other hand, this application embodiment also provides a thermal management system in which at least a portion of the first conductive port of the valve core assembly is arranged axially symmetrically, such that when the valve core assembly is in at least two symmetrical working positions, the first conductive cavity connects the first flow path relationship between the multiple first connecting ports in the same first layer. In one of the at least two symmetrical working positions of the valve core assembly, the second connecting port is closed, which facilitates the flow of fluid in the first heat exchange branch and the second heat exchange branch. In the other of the at least two symmetrical working positions of the valve core assembly, the first connecting port is connected to the second connecting port through the first conductive cavity and the second conductive cavity, so that the fluid can interact between different pipelines, which facilitates the fulfillment of the functional requirements of the thermal management system and is beneficial to the heat exchange efficiency of the thermal management system.

It should be pointed out that those skilled in the art can make several modifications without departing from the concept of this invention, and these modifications all fall within the protection scope of this invention.
