Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a valve core, a multi-way valve, a thermal management system, and a vehicle. Background Technology

[0002] With the rapid development of the vehicle industry (such as new energy vehicles), its thermal management systems are becoming increasingly integrated. Among related technologies, the multi-way valve is a new type of coolant flow regulating valve in the thermal management system of new energy vehicles. The multi-way valve switches its connection state by the interaction between the valve core's switching flow channel and the valve port on the housing, and by rotating the valve core. However, in some technologies, the valve core's structural design is not reasonable enough and cannot adequately meet the usage requirements. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a valve core, a multi-way valve, a thermal management system, and a vehicle. Each switching channel of the valve core can have multiple engagement states with the valve port of the multi-way valve, enabling the multi-way valve to have multiple connection states and diversifying its switching modes to adapt to different usage requirements and improve its applicability.

[0004] In a first aspect, embodiments of this application provide a valve core having multiple separated switching channels. Each switching channel has multiple spaced-apart connecting regions at its open end. These connecting regions are adapted to switch connections with corresponding valve ports of a multi-way valve to switch the connection state of the multi-way valve. The multiple switching channels include a first switching channel, a second switching channel, and a third switching channel. The first and second switching channels are spaced apart along the circumference of the valve core. The third switching channel includes a first channel segment, a second channel segment, and a third channel segment. The third channel segment connects the first channel segment and the second channel segment. In the circumference of the valve core, the first channel segment and the second channel segment are spaced apart at both ends of the circumference of the first switching channel and at both ends of the circumference of the second switching channel. The circumferential length of the first channel segment is greater than the circumferential length of the second channel segment, such that the number of connecting regions corresponding to the first channel segment is greater than the number of connecting regions corresponding to the second channel segment.

[0005] In the above technical solution, by setting each switching channel to have multiple spaced connecting areas at its open end, each switching channel can connect to multiple valve ports, and each switching channel can also be separated from the valve ports, so that each switching channel and valve port can have multiple cooperation states. Secondly, by setting the number of connected regions corresponding to the first flow channel segment to be greater than the number of connected regions corresponding to the second flow channel segment, the first flow channel segment can connect to multiple valve ports, or the first flow channel segment can be separated from the valve ports. Similarly, the second flow channel segment can connect to multiple valve ports, or the second flow channel segment can be separated from the valve ports. Furthermore, the number of valve ports connected to the first flow channel segment can be greater than or equal to the number of valve ports connected to the second flow channel segment. This makes the cooperation state between the third switching flow channel and the valve port more diverse. Thus, each switching flow channel of the valve core can have multiple cooperation states with the valve port of the multi-way valve, and the cooperation state between each switching flow channel and the valve port of the multi-way valve can be the same or different. As the valve core rotates, each switching flow channel switches to the corresponding cooperation state, so that the multi-way valve has the corresponding connection state. This allows the multi-way valve to have multiple connection states, making the switching mode of the multi-way valve more diversified to adapt to different usage requirements and improve the applicability of the multi-way valve.

[0059] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0060] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0061] Hereinafter, with reference to the accompanying drawings, the valve core 2 according to an embodiment of the present invention will be described.

[0062] like Figure 1 and Figure 2 As shown, the valve core 2 according to this embodiment of the present invention has a plurality of separated switching channels 2a. The open end of each switching channel 2a has a plurality of spaced-apart communication regions 2h. The communication regions 2h are adapted to switch communication with the corresponding valve port 1a of the multi-way valve 100 to realize the switching of the communication state of the multi-way valve 100. The plurality of switching channels 2a include a first switching channel 21, a second switching channel 22 and a third switching channel 23. The first switching channel 21 and the second switching channel 22 are spaced apart along the circumference of the valve core 2. The third switching channel 23 includes a first channel segment 23. 1. The second flow channel section 232 and the third flow channel section 233 are connected to the first flow channel section 231 and the second flow channel section 232. In the circumferential direction of the valve core 2, the first flow channel section 231 and the second flow channel section 232 are respectively spaced at both ends of the circumferential direction of the first switching flow channel 21 and at both ends of the circumferential direction of the second switching flow channel 22. The circumferential length of the first flow channel section 231 is greater than the circumferential length of the second flow channel section 232, so that the number of connected regions 2h corresponding to the first flow channel section 231 is greater than the number of connected regions 2h corresponding to the second flow channel section 232.

[0063] As can be seen, in the circumferential direction of the valve core 2, the first flow channel segment 231 is spaced between one circumferential end of the first switching flow channel 21 and one circumferential end of the second switching flow channel 22, and the second flow channel segment 231 is spaced between the other circumferential end of the first switching flow channel 21 and the other circumferential end of the second switching flow channel 22. If the number of connected regions 2h corresponding to the first flow channel segment 231 is m, and the number of connected regions 2h corresponding to the second flow channel segment 232 is n, then m > n ≥ 1.

[0064] It should be noted that, in combination Figure 1 and Figure 8 Each switching channel 2a has multiple spaced connecting regions 2h at its open end. The connecting regions 2h are adapted to switch connections with the corresponding valve ports 1a of the multi-way valve 100 to switch the connection state of the multi-way valve 100. It can be understood that when the multi-way valve 100 is in a certain connection state, if the corresponding switching channel 2a is connected to multiple valve ports 1a, then the multiple connecting regions 2h of the switching channel 2a are set one-to-one with the multiple valve ports 1a. At this time, the total number of connecting regions 2h of the switching channel 2a is p, and the number of connecting regions 2h of the switching channel 2a corresponding to multiple valve ports 1a is q. 2≤q≤p, so each switching channel 2a can correspond to at most the same number of valve ports 1a as the connecting regions 2h through multiple connecting regions 2h. When the valve core 2 rotates to a suitable angle, the multiple connecting regions 2h of the switching channel 2a correspond one-to-one or partially with the valve ports 1a of the multi-way valve 100. At this time, the valve ports 1a of the multi-way valve 100 are connected to the corresponding switching channel 2a.

[0065] Each switching channel 2a has multiple spaced-apart connecting regions 2h at its open end, allowing each switching channel 2a to connect to multiple valve ports 1a. Thus, each switching channel 2a (e.g., the first switching channel 21, the second switching channel 22, and the third switching channel 23) can connect to at least one of the multiple valve ports 1a, or the switching channel 2a can be separated from the valve ports 1a, allowing the switching channel 2a to have multiple engagement states with the valve ports 1a. Therefore, each switching channel 2a of the valve core 2 can have multiple engagement states with the valve ports 1a of the multi-way valve 100, and each engagement state between the switching channel 2a and the valve ports 1a of the multi-way valve 100 can be the same or different. As the valve core 2 rotates, each switching channel 2a switches to the corresponding engagement state, giving the multi-way valve 100 a corresponding connection state, thus allowing the multi-way valve 100 to have multiple connection states. Furthermore, as the valve core 2 rotates, the multi-way valve 100 can switch between these multiple connection states.

[0066] Furthermore, the circumferential length of the first flow channel section 231 is greater than the length of the second flow channel section 232, so that the number of connected regions 2h corresponding to the first flow channel section 231 is greater than the number of connected regions 2h corresponding to the second flow channel section 232. Therefore, the number of valve ports 1a of the multi-way valve 100 corresponding to the first flow channel section 231 can be greater than the number of valve ports 1a corresponding to the second flow channel section 232. In this way, the first flow channel section 231 can connect to multiple valve ports 1a, or the first flow channel section 231 can be separated from the valve ports 1a. The second flow channel section 232 can connect to multiple valve ports 1a, or the second flow channel section 232 can be separated from the valve ports 1a. Moreover, the number of valve ports 1a connected to the first flow channel section 231 can be greater than or equal to the number of valve ports 1a connected to the second flow channel section 232. As a result, the cooperation state between the third switching flow channel 23 and the valve ports 1a is more diverse, thereby further enriching the connection state of the multi-way valve 100. This makes the switching modes of the multi-way valve 100 more diverse, so as to adapt to different usage needs and improve the applicability of the multi-way valve 100.

[0067] Optionally, the first switching channel 21 and the second switching channel 22 are spaced apart circumferentially along the valve core 2, and the circumferential length of the first switching channel 21 is greater than or equal to the circumferential length of the second switching channel 22. This allows the number of valve ports 1a corresponding to the first switching channel 21 of the multi-way valve 100 to be greater than or equal to the number of valve ports 1a corresponding to the second switching channel 22 of the multi-way valve 100, further enriching the connection states of the multi-way valve 100.

[0068] For example, combining Figure 1 and Figure 2The multi-way valve 100 includes a housing 1 and a valve core 2. The housing 1 has an assembly cavity 1e. The valve core 2 is rotatably disposed in the assembly cavity 1e. The bottom wall of the assembly cavity 1e of the housing 1 is provided with a plurality of valve ports 1a. The plurality of valve ports 1a are arranged sequentially at intervals along the circumference of the valve core 2, and each valve port 1a is arranged opposite to the valve core 2 along the axial direction of the valve core 2. A first switching channel 21, a second switching channel 22, and a third switching channel 23 are formed on the bottom wall of the valve core 2. The first switching channel 21 and the second switching channel 22 are spaced apart along the circumference of the valve core 2, and the open ends of the first switching channel 21 and the second switching channel 22 each have multiple spaced connecting regions 2h. The third switching channel 23 includes a first channel segment 231, a second channel segment 232, and a third channel segment 233. In the circumference of the valve core 2, the first channel segment 231 and the second channel segment 232 are spaced apart between the first switching channel 21 and the second switching channel 22, and the circumferential length of the first channel segment 231 is greater than the circumferential length of the second channel segment 232, that is, the number of connecting regions 2h corresponding to the first channel segment 231 is greater than the number of connecting regions 2h corresponding to the second channel segment 232. Therefore, the first switching channel 21, the second switching channel 22 and the third switching channel 23 have multiple cooperation states with the portions of the multiple valve ports 1a, so that the multi-way valve 100 has multiple communication states. Furthermore, the open ends of the first switching channel 21, the second switching channel 22 and the third switching channel 23 have the same or different communication regions 2h, which can further enrich the communication states of the multi-way valve 100.

[0069] For example, combined with Figure 1 , Figure 2 and Figure 8The open ends of the first switching channel 21 and the second switching channel 22 each have three spaced-apart connecting regions 2h. The first channel segment 231 corresponds to two connecting regions 2h, and the second channel segment 232 corresponds to one connecting region 2h. Therefore, the first switching channel 21 and the second switching channel 22 can each connect to a maximum of three valve ports 1a. The first channel segment 231 can connect to a maximum of two valve ports 1a, and the second channel segment 232 can connect to a maximum of one valve port 1a. Thus, the first switching channel 21 can connect to three valve ports 1a, two valve ports 1a, or one valve port 1a, or the first switching channel 21 can be separated by valve ports 1a. Similarly, the second switching channel 22 can also connect to three valve ports 1a, two valve ports 1a, or one valve port 1a, or the first switching channel 21 can be separated by valve ports 1a. The first flow channel section 231 can connect to two valve ports 1a or one valve port 1a, or the first flow channel section 231 can be separated from valve ports 1a. The second switching flow channel 22 can connect to one valve port 1a or the second switching flow channel 22 can be separated from valve ports 1a, such that the third switching flow channel 23 can connect to three valve ports 1a, two valve ports 1a, or one valve port 1a, or the third switching flow channel 23 can be separated from valve ports 1a. Thus, the first switching flow channel 21 and the second switching flow channel 22 can each have four engagement states with valve ports 1a, and the third switching flow channel 23 can have six engagement states with valve ports 1a. The engagement states of the first switching flow channel 21, the second switching flow channel 22, and the third switching flow channel 23 can be combined to give the multi-way valve 100 multiple connection states.

[0070] In the above technical solution, by setting each switching channel 2a to have multiple spaced connecting regions 2h at its open end, each switching channel 2a can connect to multiple valve ports 1a, and each switching channel 2a can also be separated from valve ports 1a, allowing each switching channel 2a and valve port 1a to have multiple engagement states. Secondly, by setting the number of connecting regions 2h corresponding to the first channel segment 231 to be greater than the number of connecting regions 2h corresponding to the second channel segment 232, the first channel segment 231 can connect to multiple valve ports 1a, or the first channel segment 231 can be separated from valve ports 1a; the second channel segment 232 can connect to multiple valve ports 1a, or the second channel segment 232 can be separated from valve ports 1a; and the number of valve ports 1a connected to the first channel segment 231 can be greater than or equal to the number of valve ports 1a connected to the second channel segment 232, making the engagement states of the third switching channel 23 and valve ports 1a even more diverse. The valve core 2 has a variety of switching channels 2a, which can have multiple matching states with the valve port 1a of the multi-way valve 100. The matching states between each switching channel 2a and the valve port 1a of the multi-way valve 100 can be the same or different. As the valve core 2 rotates, each switching channel 2a switches to the corresponding matching state, so that the multi-way valve 100 has the corresponding connection state. This allows the multi-way valve 100 to have multiple connection states, making the switching mode of the multi-way valve 100 more diversified, so as to adapt to different usage requirements and improve the applicability of the multi-way valve 100.

[0071] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, in the axial direction of valve core 2, one end of the switching flow channel 2a is open and the other end is closed.

[0072] For example, combining Figure 2 The multi-way valve 100 includes a housing 1 and a valve core 2. The housing 1 has an assembly cavity 1e. The valve core 2 is formed in a disc shape and is rotatably disposed in the assembly cavity 1e. The bottom wall of the assembly cavity 1e of the housing 1 is provided with multiple valve ports 1a. Multiple switching channels 2a are formed on the valve core 2. Each switching channel 2a is open on the side facing the valve port 1a and closed on the axial side away from the valve port 1a. Thus, the valve core 2 and the housing 1 can be fitted more compactly in the axial direction of the valve core 2, and the overall volume of the valve core 2 and the housing 1 can be reduced accordingly (for example, the overall size of the multi-way valve 100 is 128mm×130mm×78mm). This allows the multi-way valve 100 to occupy less space in the axial direction of the valve core 2 and enables the multi-way valve 100 to achieve multiple modes in a smaller volume.

[0073] In the above technical solution, by setting one end of the switching flow channel 2a open and the other end closed in the axial direction of the valve core 2, the valve core 2 and the housing 1 can be more compactly matched in the axial direction of the valve core 2, which can adaptably reduce the volume of the valve core 2 in the axial direction, and is beneficial to reduce the volume of the multi-way valve 100 in the axial direction.

[0074] In some embodiments of this application, such as Figure 2 As shown, in the axial direction of the valve core 2, the periphery of the open end of the switching flow channel 2a has a sealing rib 2e, the sealing rib 2e is arranged around the open end of the switching flow channel 2a, and the width of the sealing rib 2e is less than the thickness of the side wall of the switching flow channel 2a.

[0075] For example, combining Figure 2 and Figure 5 The multi-way valve 100 includes a housing 1 and a valve core 2. The housing 1 has an assembly cavity 1e, and the valve core 2 is rotatably disposed within the assembly cavity 1e. Multiple valve ports 1a are provided on the bottom wall of the assembly cavity 1e of the housing 1. A switching flow channel 2a is formed on the valve core 2, which is open axially toward the valve port 1a. The periphery of the open end of the switching flow channel 2a has a sealing rib 2e, which can seal against the bottom wall of the assembly cavity 1e to improve the dynamic sealing between the housing 1 and the valve core 2. Alternatively, the switching flow channel 2a can be configured such that both ends of the switching flow channel 2a are open axially in the valve core 2.

[0076] In the above technical solution, by setting a sealing rib 2e around the open end of the switching channel 2a, the sealing performance between the open end of the switching channel 2a and the corresponding component of the multi-way valve 100 can be improved.

[0077] In some embodiments of this application, the cross-section of the sealing rib 2e is semi-circular, semi-elliptical, square, or trapezoidal.

[0078] In the above technical solution, the cross-sectional shape of the sealing rib 2e can be selected in a variety of ways to adapt to the structure of the valve core 2 and the working environment of the valve core 2, so as to ensure the sealing between the valve core 2 and the corresponding parts of the multi-way valve 100.

[0079] In some embodiments of this application, combined with Figure 1 At least two connecting regions 2h of the switching channel 2a are arranged adjacent to each other. That is, for a single switching channel 2a, no other connecting regions 2h of the switching channel 2a are arranged between the aforementioned at least two connecting regions 2h of the switching channel 2a. The portion of the switching channel 2a corresponding to the at least two connecting regions 2h extends along the circumferential arc of the valve core 2. The valve core 2 includes a body 25 and a pivot shaft 24. Multiple switching channels 2a are formed on the body 25. The axial ends of the pivot shaft 24 extend beyond the axial ends of the body 25. The third channel segment 233 is arranged around the pivot shaft 24.

[0080] For example, combining Figure 1 and Figure 2 The first switching channel 21 and the second switching channel 22 each correspond to three adjacent connected regions 2h, and the three adjacent connected regions 2h extend along the circumferential arc of the valve core 2. The first channel segment 231 corresponds to two adjacent connected regions 2h, and the two adjacent connected regions 2h also extend along the circumferential arc of the valve core 2. Thus, as the valve core 2 rotates, the first switching channel 21, the second switching channel 22, and the third switching channel 23 can cooperate with the corresponding valve ports 1a, so that the multi-way valve 100 can switch smoothly between multiple connected states.

[0081] The valve core 2 includes a body 25 and a pivot shaft 24. The pivot shaft 24 is located on the body 25 corresponding to the rotation axis of the valve core 2. The third flow channel section 233 connects the first flow channel section 231 and the second flow channel section 232 that are opposite each other in the radial direction of the valve core 2. The third flow channel section 233 is divided into two parts, and the two parts are respectively arranged around the pivot shaft 24 half a circle, so that the third flow channel section 233 connects the first flow channel section 231 and the second flow channel section 232 in the radial direction of the valve core 2, which can make the medium flow between the first flow channel section 231 and the second flow channel section 232 smoother.

[0082] In the above technical solution, by setting at least two corresponding connecting regions 2h of the switching flow channel 2a to extend along the circumferential arc of the valve core 2, the first switching flow channel 21, the second switching flow channel 22, and the third switching flow channel 23 can cooperate with the corresponding valve port 1a in the circumferential direction of the valve core 2, so that the multi-way valve 100 can switch smoothly between multiple connection states. By setting the third flow channel segment 233 to surround the pivot shaft 24, interference between the third flow channel segment 233 and the pivot shaft 24 is avoided, and the third flow channel segment 233 connects the opposite first flow channel segment 231 and second flow channel segment 232 in the radial direction of the valve core 2, the medium flow between the first flow channel segment 231 and the second flow channel segment 232 can be made smoother.

[0083] In some embodiments of this application, the switching channel 2a is configured to satisfy at least one of the following conditions: Condition A1, the circumferential ends of the orthographic projection of the corresponding at least two connected regions 2h of the switching channel 2a onto a preset plane are arc-shaped, and the preset plane is perpendicular to the axial direction of the valve core 2; Condition A2, the switching channel 2a includes a first channel portion 2f and a second channel portion 2g arranged sequentially along the axial direction of the valve core 2, the side of the first channel portion 2f away from the second channel portion 2g is open, the side of the second channel portion 2g away from the first channel portion 2f is closed, and at least a portion of the cross-sectional shape of the second channel portion 2g is semi-circular; Condition A3, the switching channel 2a includes a first channel portion 2f and a second channel portion 2g arranged sequentially along the axial direction of the valve core 2, and on the longitudinal section of the valve core 2, the wall surface of the first channel portion 2f is tangent to the wall surface of the second channel portion 2g, and the longitudinal section passes through the central axis of the valve core 2.

[0084] In some embodiments, combined with Figure 1 The switching channel 2a is constructed to satisfy condition A1. The circumferential ends of the orthographic projection of the portion of the switching channel 2a corresponding to at least two connected regions 2h on the preset plane are arc-shaped. The preset plane is perpendicular to the axial direction of the valve core 2. Then the portion of the switching channel 2a corresponding to at least two connected regions 2h extends along the circumference of the valve core 2, so that the portion of the switching channel 2a corresponding to the connected region 2h can guide the flow of the medium, thereby reducing the resistance of the medium flowing in the switching channel 2a.

[0085] In some embodiments, combined with Figure 2 The switching channel 2a is configured to satisfy condition A2. The switching channel 2a includes a first channel portion 2f and a second channel portion 2g arranged sequentially along the axial direction of the valve core 2. The side of the first channel portion 2f away from the second channel portion 2g is open, and the side of the second channel portion 2g away from the first channel portion 2f is closed. At least a portion of the second channel portion 2g has a semi-circular cross-sectional shape, which allows at least a portion of the second channel portion 2g to guide the flow of the medium and reduce the resistance of the medium when it flows in the second channel portion 2g, thereby reducing the resistance of the medium when it flows in the switching channel 2a.

[0086] For example, combining Figure 2 Each switching channel 2a includes a first channel portion 2f and a second channel portion 2g arranged sequentially along the axial direction of the valve core 2. The side of the first channel portion 2f facing away from the second channel portion 2g is open, and the side of the second channel portion 2g facing away from the first channel portion 2f is closed. The cross-sectional shape of the second channel portion 2g is semi-circular. For example, the second channel portion 2g is formed by uniformly scanning a sphere, which reduces the resistance of the medium flowing in the second channel portion 2g. At this time, if the switching channel 2a satisfies condition A1, a portion of the wall surface of the switching channel 2a can be formed by rotating a semi-circular arc in the circumferential direction.

[0087] In some embodiments, combined with Figure 2 The switching channel 2a is configured to satisfy condition A3. The switching channel 2a includes a first channel section 2f and a second channel section 2g arranged sequentially along the axial direction of the valve core 2. On the longitudinal section of the valve core 2, the wall surface of the first channel section 2f is tangent to the wall surface of the second channel section 2g. The longitudinal section passes through the central axis of the valve core 2, so the wall surface of the first channel section 2f and the wall surface of the second channel section 2g are connected perpendicularly. This can prevent the medium from flowing poorly at the connection between the walls of the first channel section 2f and the second channel section 2g, and can reduce the resistance of the medium flowing in the switching channel 2a.

[0088] In the above technical solution, by setting the switching channel 2a to satisfy at least one of multiple conditions (such as condition A1, condition A2 and condition A3), the resistance of the medium flowing in the switching channel 2a can be reduced and the smoothness of the medium flowing in the switching channel 2a can be improved.

[0089] In some embodiments of this application, combined with Figure 1 and Figure 2 If the switching channel 2a satisfies conditions A2 and A3, the connecting region 2h is a circular region, and the cross-sectional radius of at least a portion of the second channel portion 2g is equal to the radius of the connecting region 2h, then the radial width of the first channel portion 2f in the valve core 2, the cross-sectional radius of at least a portion of the second channel portion 2g, and the radius of the connecting region 2h are all equal, which can reduce the resistance of the medium flowing into the switching channel 2a from the open end; and / or, in the axial direction of the valve core 2, the height of the first channel portion 2f is h, and the height of the second channel portion 2g is the cross-sectional radius r1 of at least a portion of the second channel portion 2g, 0 < h ≤ r1, so that the height of the first channel portion 2f is within a suitable range, which can make the switching channel 2a have a suitable medium flow volume to ensure that a suitable amount of medium can flow in the switching channel 2a, which is beneficial to improving the performance of the multi-way valve 100, while not making the axial length of the valve core 2 too large.

[0090] For example, in some examples, the circumference of the open end of the switching channel 2a in the axial direction of the valve core 2 has a sealing rib 2e, which is arranged around the open end of the switching channel 2a. In the axial direction of the valve core 2, the sum of the height of the first channel portion 2f and the height of the sealing rib 2e is 1.12*r1.

[0091] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0092] Optionally, in the axial direction of the valve core 2, the periphery of the open end of the switching channel 2a has a sealing rib 2e, the sealing rib 2e is arranged around the open end of the switching channel 2a, and the sealing rib 2e is provided on one side of the wall of the first channel portion 2f in the axial direction, then the height of the first channel portion 2f (excluding the height of the sealing rib 2e) is h.

[0093] Optionally, combined Figure 5 The switching channel 2a satisfies conditions A2 and A3, the connected region 2h is a circular region, and the radius of the valve port 1a is equal to the radius of the connected region 2h. Therefore, when the switching channel 2a and the valve port 1a are engaged, the walls at the connection point of the switching channel 2a and the valve port 1a are tangent, which can effectively reduce the resistance to medium flow. In some embodiments of this application, combined with... Figure 1 In the circumferential direction of valve core 2, the circumferential length of the first switching channel 21 and the circumferential length of the second switching channel 22 are both greater than the length of the first channel segment 231, so that the number of connected regions 2h corresponding to the first switching channel 21 and the second switching channel 22 is greater than the number of connected regions 2h corresponding to the first channel segment 231.

[0094] In the above technical solution, by setting the number of connected regions 2h corresponding to the first switching channel 21 and the second switching channel 22 to be greater than the number of connected regions 2h corresponding to the first channel segment 231, the first switching channel 2a and the second switching channel 22 can connect more valve ports 1a compared to the first channel segment 231, so that the first switching channel 21 and the second switching channel 22 can have more matching states, thereby allowing the multi-way valve 100 to have more connected states to better adapt to different usage requirements.

[0095] In some embodiments of this application, combined with Figure 1 Each of the first switching channel 21 to the third switching channel 23 has three connected regions 2h. The center of the connected regions 2h of the first switching channel 21 to the third switching channel 23 is located on the first cylindrical surface. The first cylindrical surface has nine reference points 5 that are equally spaced along the circumference of the valve core 2. The nine reference points 5 are the first reference point 51 to the last reference point 59 arranged sequentially along the circumference of the valve core 2. The first reference point 51 to the third reference point 53 are the centers of the three connected regions 2h of the first switching channel 21, the fourth reference point 54 and the fifth reference point 55 are the centers of the two connected regions 2h of the first channel segment 231, the sixth reference point 56 to the eighth reference point 58 are the centers of the three connected regions 2h of the second switching channel 22, and the last reference point 59 is the center of the connected region 2h of the second channel segment 232.

[0096] It can be seen that the circumferential lengths of the first switching channel 21 and the second switching channel 22 in the circumferential direction of the valve core 2 are equal. The circumferential distances between the first switching channel 21 and the first channel segment 231 in the circumferential direction of the valve core 2, the second switching channel 22 and the first channel segment 231 in the circumferential direction of the valve core 2, the first switching channel 21 and the second channel segment 232 in the circumferential direction of the valve core 2, and the second switching channel 22 and the second channel segment 232 in the circumferential direction of the valve core 2 are all pairwise equal. Furthermore, the first switching channel 21 and the second switching channel 22 correspond to three connected regions 2h, thus the first switching channel 21 and the second switching channel 22 can connect two or three valve ports 1a. The first flow channel segment 231 corresponds to two connected regions 2h, and the second flow channel segment 232 corresponds to one connected region 2h. Therefore, the first flow channel segment 231 can connect to one or two valve ports 1a, the second flow channel segment 232 can connect to one valve port 1a, and the third flow channel segment 233 connects the first flow channel segment 231 and the second flow channel segment 232. Thus, the third switching flow channel 23 can connect to two or three valve ports 1a. On a plane perpendicular to the rotation axis of the valve core 2, with the orthographic projection of the rotation axis of the valve core 2 as the center, the central angles corresponding to the first switching flow channel 21 and the second switching flow channel 22 are both greater than 80°, and the central angle corresponding to the first flow channel segment 231 is greater than 40°. Therefore, by setting the arrangement of the switching flow channels 2a and the correspondence between the switching flow channels 2a and the valve ports 1a, the corresponding switching flow channels 2a can connect to two or three valve ports 1a, enabling the multi-way valve 100 to have multiple connection states.

[0097] Secondly, this application provides a multi-way valve 100, including a housing 1 and a valve core 2 according to the first aspect embodiment above. The housing 1 has a plurality of valve ports 1a, and the valve core 2 is rotatably disposed in the housing 1 so as to switch the connection state of the multi-way valve 100 by switching the connection between the connection region 2h and the corresponding valve port 1a.

[0098] In the above technical solution, by adopting the valve core 2, the multiple connection states of the multi-way valve 100 can be switched alternately, making the switching mode of the multi-way valve 100 more diversified.

[0099] In some embodiments of this application, combined with Figure 7 and Figures 8-15The multiple valve ports 1a include multiple inlets 1b and multiple outlets 1c. The multiple inlets 1b include a first inlet 111 and a second inlet 112. The multi-way valve 100 has a first mode and a second mode. In the first mode, the first inlet 111 and the second inlet 112 are connected to the same outlet 1c through at least one of the switching channels 2a of the first switching channel 21, the second switching channel 22 and the third switching channel 23. The first mode has multiple first connection states. In different first connection states, the first inlet 111 is connected to different outlets 1c. In the second mode, the first inlet 111 and the second inlet 112 are connected to different outlets 1c through different switching channels 2a of the first switching channel 21 to the third switching channel 23. The second mode has multiple second connection states. In different second connection states, at least one of the first inlet 111 and the second inlet 112 is connected to different outlets 1c.

[0100] It can be seen that in the first mode, regardless of the first connection state, the first inlet 111 and the second inlet 112 are both connected to one outlet 1c. If the first inlet 111 and the second inlet 112 switch from being connected to one outlet 1c to being connected to another outlet 1c, it indicates that the multi-way valve 100 has switched from one first connection state to another different first connection state. In the second mode, regardless of the second connection state, the first inlet 111 and the second inlet 112 are connected to different outlets 1c. If at least one of the first inlet 111 and the second inlet 112 switches to being connected to another outlet 1c, while still ensuring that the first inlet 111 and the second inlet 112 are connected to different outlets 1c, it indicates that the multi-way valve 100 has switched from one second connection state to another different second connection state. Therefore, if the number of outlets 1c is a positive integer greater than or equal to 1, then the number of first connection states is less than or equal to 1, and the number of second connection states is less than or equal to the number of permutations. (i.e., n*(n-1)).

[0101] Therefore, when the media at the first inlet 111 and the second inlet 112 need to achieve the same flow direction after passing through the multi-way valve 100, the multi-way valve 100 can be switched to the corresponding first connection state in the first mode according to the flow direction requirements of the media at the first inlet 111 and the second inlet 112; when the media at the first inlet 111 and the second inlet 112 need to achieve different flow directions after passing through the multi-way valve 100, the multi-way valve 100 can be switched to the corresponding second connection state in the second mode according to the flow direction requirements of the media at the first inlet 111 and the second inlet 112.

[0102] Clearly, the rotational engagement between the valve core 2 and the housing 1 enables the multi-way valve 100 to function as a reversing valve. In the first mode, the first inlet 111 and the second inlet 112 can switch to connect to the same outlet 1c, and the outlet 1c can be any two of a plurality of outlets 1c, allowing the multi-way valve 100 to switch between multiple first connection states. In the second mode, the first inlet 111 and the second inlet 112 can switch to connect to different outlets 1c, and at least one of the first inlet 111 and the second inlet 112 is different from the connected outlet 1c, allowing the multi-way valve 100 to switch between multiple second connection states. Of course, the multi-way valve 100 can also switch between multiple first connection states and multiple second connection states. Therefore, the multi-way valve 100 has multiple connection states and a reversing function, enabling alternating switching of multiple connection states, making the switching modes of the multi-way valve 100 more diverse to adapt to different usage requirements and improve the applicability of the multi-way valve 100. Secondly, when the multi-way valve 100 is applied to the thermal management system 200, the setting of corresponding components (such as valves and pipelines) can be reduced, realizing integrated layout, which is conducive to reducing costs and saving installation space. Moreover, the thermal management system 200 can switch between multiple modes to meet more thermal management conditions.

[0103] For example, combining Figure 5 and Figures 8-15 The multi-way valve 100 includes a housing 1 and a valve core 2. The housing 1 includes a bottom shell 11 and a cover plate 12. An open assembly cavity 1e is formed in the bottom shell 11. The valve core 2 is installed in the assembly cavity 1e. The cover plate 12 is installed in the bottom shell 11 and is used to close the open end of the assembly cavity 1e. The valve core 2 is configured to be rotatable relative to the housing 1. A drive member 5 is also installed on the cover plate 12. The output end of the drive member 5 is poweredly connected to the valve core 2, so that the drive member 5 can drive the valve core 2 to rotate around its own rotation axis, so that the multi-way valve 100 has a first mode and a second mode. In different modes, the multi-way valve 100 has multiple connection states (first connection state and second connection state).

[0104] The bottom wall of the assembly cavity 1e of the housing 1 is provided with a plurality of valve ports 1a. The plurality of valve ports 1a are arranged sequentially at intervals along the circumference of the valve core 2, and each valve port 1a is arranged opposite to the valve core 2 along the axial direction of the valve core 2. The valve core 2 has a first switching flow channel 21, a second switching flow channel 22 and a third switching flow channel 23, and the first switching flow channel 21, the second switching flow channel 22 and the third switching flow channel 23 are separated. The valve ports 1a can communicate with the switching flow channel 2a used for the flow medium. The plurality of valve ports 1a include a plurality of inlets 1b and a plurality of outlets 1c. The plurality of inlets 1b include a first inlet 111 and a second inlet 112. In the first mode, the first inlet 111 and the second inlet 112 are connected to the same outlet 1c through any one of the first switching channel 21, the second switching channel 22 and the third switching channel 23. The first mode has multiple first connection states. In different first connection states, the first inlet 111 is connected to different outlets 1c. In the second mode, the first inlet 111 and the second inlet 112 are connected to different outlets 1c through two of the first switching channel 21, the second switching channel 22 and the third switching channel 23, respectively. The second mode has multiple second connection states. In different second connection states, at least one of the first inlet 111 and the second inlet 112 is connected to different outlets 1c.

[0105] Of course, the location of the multiple valve ports 1a is not limited to this. For example, the multiple valve ports 1a can also be located on the side wall of the assembly cavity 1e of the housing 1, with the multiple valve ports 1a arranged sequentially at intervals along the circumference of the valve core 2, and each valve port 1a arranged opposite to the valve core 2 along the radial direction of the valve core 2; or, for example, at least one of the multiple valve ports 1a is located on the bottom wall of the assembly cavity 1e of the housing 1, and the remaining valve ports 1a are located on the side wall of the assembly cavity 1e of the housing 1.

[0106] It should be noted that there are two or more inlets 1b. During the rotation of valve core 2, in the first mode, the first inlet 111 and the second inlet 112 are connected to the same inlet 1b through any one of the first switching channel 21, the second switching channel 22 and the third switching channel 23. Under different first connection states, the first inlet 111 is connected to different outlets 1c, so that the first mode has multiple first connection states. In the second mode, the first inlet 111 and the second inlet 112 are connected to different outlets 1c through two of the first switching channel 21, the second switching channel 22 and the third switching channel 23, respectively. The second mode has multiple second connection states. Under different second connection states, at least one of the first inlet 111 and the second inlet 112 is connected to different outlets 1c, so that the second mode has multiple second connection states.

[0107] For example, such as Figures 8-15As shown, the multiple inlets 1b include a first inlet 111 and a second inlet 112, the multiple outlets 1c include a first outlet 113, a second outlet 114, and a third outlet 115, and the multiple switching channels 2a include a first switching channel 21, a second switching channel 22, and a third switching channel 23. In a first mode, the multi-way valve 100 has three first connection states. In the first first connection state, the first inlet 111 and the second inlet 112 are connected to the first outlet 113 through the first switching channel 21 or the second switching channel 22. In the second first connection state, the first inlet 111 and the second inlet 112 are connected to the second outlet 114 through the first switching channel 21 or the second switching channel 22. In the third first connection state, the first inlet 111 and the second inlet 112 are connected to the third outlet 115 through the third switching channel 23. In the second mode, the multi-way valve 100 has three second connection states. In the first second connection state, the first inlet 111 is connected to the first outlet 113 through the first switching channel 21, and the second inlet 112 is connected to the third outlet 115 through the third switching channel 23. In the second connection state, the first inlet 111 is connected to the third outlet 115 through the third switching channel 23, and the second inlet 112 is connected to the second outlet 114 through the second switching channel 22. In the third connection state, the first inlet 111 is connected to the first outlet 113 through the second switching channel 22, and the second inlet 112 is connected to the second outlet 114 through the third switching channel 23, or the first inlet 111 is connected to the first outlet 113 through the third switching channel 23, and the second inlet 112 is connected to the second outlet 114 through the first switching channel 21.

[0108] The above embodiments are merely illustrative and do not limit the present invention. The present invention may also have two or more outlets 1c, and this application does not limit this. For example, the two outlets 1c are the first outlet 113 and the second outlet 114. In the first mode, the first inlet 111 and the second inlet 112 can both be connected to the first outlet 113, and the first inlet 111 and the second inlet 112 can both be connected to the second outlet 114, so that the first mode has two first connection states; in the second mode, the first inlet 111 is connected to the first outlet 113, the second inlet 112 is connected to the second outlet 114, the first inlet 111 is connected to the second outlet 114, and the second inlet 112 is connected to the first outlet 113, so that the second mode has two second connection states.

[0109] In the above technical solution, by setting it in the first mode, the first inlet 111 and the second inlet 112 can select one of multiple different outlets 1c to switch connections, so that the multi-way valve 100 has multiple first connection states, and the multi-way valve 100 can switch between multiple first connection states; in the second mode, the first inlet 111 and the second inlet 112 can switch connections with different outlets 1c respectively, and at least one of the first inlet 111 and the second inlet 112 can switch to connect with different outlets 1c, so that the multi-way valve 100 has multiple second connection states, and the multi-way valve 100 can switch between multiple second connection states. Therefore, the multi-way valve 100 has a reversing function, and the multi-way valve 100 can switch between multiple connection states (multiple first connection states and multiple second connection states), making the switching modes of the multi-way valve 100 more diversified to adapt to different usage requirements and improve the applicability of the multi-way valve 100.

[0110] Optionally, the opening areas of inlet 1b and outlet 1c are equal. For example, both inlet 1b and outlet 1c are formed as circular openings, and the opening diameters of both inlet 1b and outlet 1c are 15.8 mm.

[0111] In some embodiments of this application, the multi-way valve 100 is configured to satisfy at least one of the following conditions: Condition B1, in at least two first connection states, the first inlet 111 is connected to different outlets 1c through the same switching channel 2a; Condition B2, in different second connection states, one of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the third switching channel 23; Condition B3, in the first mode, the multiple switching channels 2a used to connect the corresponding valve port 1a constitute a first set, and in the second mode, the multiple switching channels 2a used to connect the corresponding valve port 1a constitute a second set, and the first set is a subset of the second set; Condition B4, the number of outlets 1c and the number of switching channels 2a are both three or more, and in any first connection state, except for the outlet 1c connected to the first inlet 111, the other multiple outlets 1c are separated by different switching channels 2a.

[0112] In some embodiments, such as Figure 8 and Figure 11 As shown, the multi-way valve 100 is configured to satisfy condition B1, in at least two first connection states, the first inlet 111 is connected to different outlets 1c through the same switching channel 2a, and at least one of the multiple switching channels 2a enables the multi-way valve 100 to achieve at least two first connection states, which is beneficial to reducing the number of switching channels 2a.

[0113] For example, multiple outlets 1c include a first outlet 113, a second outlet 114, and a third outlet 115. When the valve core 2 rotates to a certain angle position, it engages... Figure 11Both the first inlet 111 and the second inlet 112 are connected to the first outlet 113 through the first switching flow channel 21. When the valve core 2 rotates to another angular position, it combines... Figure 8 The first inlet 111 and the second inlet 112 are connected to the second outlet 114 through the first switching channel 21; and / or, when the valve core 2 rotates to a certain angle position, it engages with... Figure 10 The first inlet 111 and the second inlet 112 are connected to the first outlet 113 through the second switching channel 22. When the valve core 2 rotates to another angle position, it combines... Figure 9 The first inlet 111 and the second inlet 112 are connected to the second outlet 114 through the second switching channel 22.

[0114] In some embodiments, such as Figure 12 As shown, the multi-way valve 100 is configured to satisfy condition B2. In different second connection states, one of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the third switching channel 23. Therefore, in different second connection states, the valve core 2 can connect one of the first inlet 111 and the second inlet 112 to the corresponding outlet 1c through the third switching channel 23. This allows for flexible arrangement of the switching channels 2a, improving the practicality of the multi-way valve 100 and reducing its layout complexity. It is evident that the third switching channel 23 is always in operation to achieve medium flow in different second connection states. This switching channel 2a can cooperate with other switching channels 2a to achieve different second connection states, which helps reduce the number of switching channels 2a and simplifies the arrangement of multiple switching channels 2a.

[0115] For example, the multi-way valve 100 can be configured to: maintain two different second connection states (such as...) Figure 13 and Figure 14 As shown), the second inlet 112 (or the first inlet 111) is connected to different outlets 1c through the third switching channel 23. In this case, under the two different second connection states mentioned above, the first inlet 111 can be connected to the same outlet 1c; and / or, under the two different second connection states (such as...), Figure 13 and Figure 14 As shown), the same outlet 1c is switched to connect to the first inlet 111 and the second inlet 112 through the third switching channel 23. That is, in one of the second connected states, the outlet 1c is connected to the first inlet 111 through the third switching channel 23, and in the other second connected state, the outlet 1c is connected to the second inlet 112 through the third switching channel 23.

[0116] Optionally, in all second connection states, the third switching channel 23 is in operation to enable medium flow. Taking three second connection states as an example, in the first second connection state, the first inlet 111 is connected to the first outlet 113 through the first switching channel 21, and the second inlet 112 is connected to the third outlet 115 through the third switching channel 23; in the second connection state, the first inlet 111 is connected to the third outlet 115 through the third switching channel 23, and the second inlet 112 is connected to the second outlet 114 through the second switching channel 22; in the third connection state, the first inlet 111 is connected to the first outlet 113 through the second switching channel 22, and the second inlet 112 is connected to the second outlet 114 through the third switching channel 23, or the first inlet 111 is connected to the first outlet 113 through the third switching channel 23, and the second inlet 112 is connected to the second outlet 114 through the first switching channel 21.

[0117] For example, taking the case where the third switching channel 23 is connected to one of the first inlet 111 and the second inlet 112 in different second connection states: in different second connection states, the third switching channel 23 connects the first inlet 111 and different outlets 1c; and / or, in different second connection states, the third switching channel 23 connects the second inlet 112 and different outlets 1c; and / or, in one second connection state, the third switching channel 23 connects the first inlet 111 and the corresponding outlet 1c, and in another second connection state, the third switching channel 23 connects the second inlet 112 and the corresponding outlet 1c.

[0118] In some embodiments, the multi-way valve 100 is configured to satisfy condition B3. In a first mode, multiple switching channels 2a used to connect the corresponding valve port 1a constitute a first set, that is, in all first connection states, all switching channels 2a involved in connecting the inlet 1b (at least one of the first inlet 111 and the second inlet 112) and the corresponding outlet 1c constitute the first set. In a second mode, multiple switching channels 2a used to connect the corresponding valve port 1a constitute a second set, that is, in all second connection states, all switching channels 2a involved in connecting either the first inlet 111 or the second inlet 112 and the corresponding outlet 1c constitute the second set. The first set is a subset of the second set, so each switching channel 2a in the first set belongs to the second set. This helps to reduce the number of switching channels 2a in the valve core 2, fully utilize the flow space provided by the valve core 2, and facilitates reducing the complexity of the arrangement of the switching channels 2a.

[0119] For example, combined Figures 8-15The first mode has three first connection states. In the first first connection state, the first switching channel 21 or the second switching channel 22 connects the first inlet 111, the second inlet 112 and the first outlet 113. In the second first connection state, the first switching channel 21 or the second switching channel 22 connects the first inlet 111, the second inlet 112 and the second outlet 114. In the third first connection state, the third switching channel 23 connects the first inlet 111, the second inlet 112 and the third outlet 115. Then the first switching channel 21 and the third switching channel 23 can form a first set, or the second switching channel 22 and the third switching channel 23 can form a first set, or the first switching channel 21, the second switching channel 22 and the third switching channel 23 can form a first set. The second mode has three second connection states. In the first second connection state, the first switching channel 21 connects the first inlet 111 and the first outlet 113, and the third switching channel 23 connects the second inlet 112 and the second outlet 114, or the third switching channel 23 connects the first inlet 111 and the first outlet 113, and the second switching channel 22 connects the second inlet 112 and the second outlet 114. In the second second connection state, the third switching channel 23 connects the first inlet 111 and the third outlet 115, and the first switching channel 21 connects the second inlet 112 and the second outlet 114. In the third second connection state, the third switching channel 23 connects the second inlet 112 and the third outlet 115, and the second switching channel 22 connects the first inlet 111 and the first outlet 113. Then, the first switching channel 21, the second switching channel 22, and the third switching channel 23 constitute the second set.

[0120] In some embodiments, combined with Figures 5-12 The multi-way valve 100 is configured to satisfy condition B4, with three or more outlets 1c and switching channels 2a. In any first connected state, except for the outlet 1c connected to the first inlet 111, the remaining outlets 1c are separated by different switching channels 2a, meaning they are disconnected from each other. In any first connected state, all outlets 1c not connected to the first inlet 111 or the second inlet 112 are connected to different switching channels 2a, thus isolating them from each other through multiple switching channels 2a. When the multi-way valve 100 is used in the thermal management system 200, the flow paths connected to the remaining outlets 1c are also disconnected from each other to ensure the normal operation of the thermal management system 200.

[0121] For example, combined Figures 5-12Taking three outlets 1c and three first connection states in the first mode as an example: In the first first connection state, any one of the first switching channel 21 and the second switching channel 22 connects the first inlet 111, the second inlet 112 and the first outlet 113, and the second outlet 114 and the third outlet 115 are separated by the remaining switching channel 2a; In the second first connection state, any one of the first switching channel 21 and the second switching channel 22 connects the first inlet 111, the second inlet 112 and the second outlet 114, and the first outlet 113 and the third outlet 115 are separated by the remaining switching channel 2a; In the third first connection state, the third switching channel 23 connects the first inlet 111, the second inlet 112 and the third outlet 115, and the first outlet 113 and the second outlet 114 are separated by the first switching channel 21 and the second switching channel 22, respectively.

[0122] It should also be noted that the multi-way valve 100 is constructed to satisfy the following conditions: condition B1, condition B2, condition B3, and condition B4. Conditions B1, B2, B3, and B4 can be satisfied individually, and any two, three, or four of the multiple conditions can be combined to satisfy them. This makes the setting of the valve port 1a and the switching flow channel 2a of the multi-way valve 100 more diverse, which is conducive to the flexible arrangement of the valve port 1a and the switching flow channel 2a, improves the practicality of the multi-way valve 100, and reduces the layout difficulty of the multi-way valve 100.

[0123] In the above technical solution, by setting the multi-way valve 100 to satisfy at least one of multiple conditions (such as condition B1, condition B2, condition B3 and condition B4), the valve port 1a and switching flow channel 2a of the multi-way valve 100 can be set in a more diverse manner, which is conducive to the flexible arrangement of the valve port 1a and switching flow channel 2a and improves the practicality of the multi-way valve 100.

[0124] In some embodiments of this application, combined with Figure 1 , Figure 7 and Figure 16 All connected regions 2h are located at one end of the axial direction of valve core 2. In the axial direction of valve core 2, one end of each switching flow channel 2a is open and the other end is closed. All valve ports 1a are located at one end of the housing 1 in the axial direction of valve core 2 and are spaced apart along the circumference of valve core 2. The center of all valve ports 1a is located on the second cylindrical surface.

[0125] In the above technical solution, by setting all valve ports 1a at intervals along the circumference of the valve core 2, and with the center of all valve ports 1a located on the second cylindrical surface, the distance between all valve ports 1a and the rotation axis of the valve core 2 is made equal. This facilitates stable switching and connection between the switching flow channel 2a and the corresponding valve port 1a when the valve core 2 and the housing 1 rotate together. Secondly, having the center of all valve ports 1a located on the second cylindrical surface simplifies the setting and processing of the valve ports 1a. Furthermore, the valve ports 1a do not occupy the portion of the housing 1 corresponding to the inner side of the cylindrical surface, thus the portion of the valve core 2 corresponding to the inner side of the cylindrical surface where the switching flow channel 2a is located is less affected by the valve ports 1a.

[0126] Optionally, the second cylindrical surface coincides with the first cylindrical surface.

[0127] In the description of this application, "axial" can be understood as the axial direction of valve core 2, that is, the direction of extension of the rotation axis of valve core 2; "radial" can be understood as the radial direction of valve core 2, that is, the direction through the rotation axis of valve core 2 in the radial plane, the radial plane being perpendicular to the axial direction of valve core 2; and "circumferential" can be understood as the direction around the rotation axis of valve core 2.

[0128] In some embodiments of this application, combined with Figure 16 Each of the first switching channel 21 to the third switching channel 23 has three connected regions 2h. The center of the connected regions 2h of the first switching channel 21 to the third switching channel 23 is located on the first cylindrical surface. The first cylindrical surface has nine reference points 5 that are equally spaced along the circumference of the valve core 2. The nine reference points 5 are the first reference point 51 to the last reference point 59 arranged sequentially along the circumference of the valve core 2. The first reference point 51 to the third reference point 53 are the centers of the three connected regions 2h of the first switching channel 21, the fourth reference point 54 and the fifth reference point 55 are the centers of the two connected regions 2h of the first channel segment 231, the sixth reference point 56 to the eighth reference point 58 are the centers of the three connected regions 2h of the second switching channel 22, and the last reference point 59 is the center of the connected region 2h of the second channel segment 232.

[0129] The housing 1 includes a first part 11a and a second part 11b arranged sequentially along the circumference of the valve core 2. The first inlet 111 and the second inlet 112 are both formed on the first part 11a and are adapted to switch communication with two adjacent connected regions 2h. All outlets 1c are formed on the second part 11b. On a plane perpendicular to the rotation axis of the valve core 2, with the orthographic projection of the rotation axis of the valve core 2 as the center, the central angle corresponding to the first part 11a is smaller than the central angle corresponding to the second part 11b. The circumferential distance between two adjacent outlets 1c is greater than the circumferential distance between two adjacent connected regions 2h.

[0130] For example, combining Figure 6 and Figure 16 The housing 1 includes a bottom shell 11 and a cover plate 12. The bottom shell 11 includes a first part 11a and a second part 11b, which are arranged sequentially along the circumference of the valve core 2. Both the first part 11a and the second part 11b are formed into an approximately fan-shaped structure. The first part 11a has a first inlet 111 and a second inlet 112, which are arranged alternately along the circumference of the valve core 2. The first inlet 111 and the second inlet 112 are adapted to switch communication with two adjacent connected regions 2h. The first inlet 11a... The first and second inlets 111 and 112 can be switched to connect with at least two corresponding switching channels 2a (e.g., the first switching channel 21, the second switching channel 22, or the first channel segment 231) corresponding to two connecting regions 2h. The second part 11b forms a plurality of outlets 1c, and all outlets 1c are arranged sequentially at intervals along the circumference of the valve core 2. In this way, the first inlet 111 and the second inlet 112 are spaced apart from all outlets 1c along the circumference of the valve core 2, which facilitates the switching channels 2a of the valve core 2 to connect with the corresponding inlets 1b and outlets 1c as the valve core 2 rotates, so that the multi-way valve 100 has multiple connection states.

[0131] In this configuration, on a plane perpendicular to the rotation axis of valve core 2, with the orthographic projection of the rotation axis of valve core 2 as the center, the central angle corresponding to the first part 11a is smaller than the central angle corresponding to the second part 11b. The circumferential distance between two adjacent outlets 1c is greater than the circumferential distance between two adjacent connected regions 2h. Therefore, the circumferential distance between two adjacent outlets 1c is greater than the circumferential distance between two adjacent inlets 1b (first inlet 111 and second inlet 112). This makes the arrangement of multiple outlets 1c in the circumferential direction of valve core 2 different from the arrangement of two inlets 1b in the circumferential direction of valve core 2. This facilitates the connection of multiple switching channels 2a of valve core 2 with the corresponding outlets 1c and inlets 1b, so as to realize multiple modes of valve core 2 (e.g., first mode and second mode).

[0132] In the above technical solution, by setting the first inlet 111 and the second inlet 112 to be formed on the first part 11a and all outlets 1c to be formed on the second part 11b, the first inlet 111 and the second inlet 112 and all outlets 1c are spaced apart along the circumference of the valve core 2, so that the first inlet 111 and the second inlet 112 are arranged in a relatively concentrated manner and all outlets 1c are arranged in a relatively concentrated manner. This makes it easier for the switching flow channel 2a of the valve core 2 to connect the corresponding inlet 1b and outlet 1c as the valve core 2 rotates, so as to realize the first mode and the second mode. This is beneficial to simplify the arrangement of multiple switching flow channels 2a to a certain extent. Secondly, by setting the circumferential spacing between two adjacent outlets 1c to be greater than the circumferential spacing between two adjacent connected regions 2h, the circumferential spacing between two adjacent outlets 1c is greater than the circumferential spacing between two adjacent inlets 1b (first inlet 111 and second inlet 112). This makes the arrangement of multiple outlets 1c in the circumferential direction of the valve core 2 different from the arrangement of two inlets 1b in the circumferential direction of the valve core 2. This facilitates the connection of multiple switching channels 2a of the valve core 2 with the corresponding outlets 1c and inlets 1b, so as to realize multiple modes of the valve core 2 (such as the first mode and the second mode).

[0133] Optionally, combined Figure 6 and Figure 16 The housing 1 includes a bottom shell 11 and a cover plate 12. An open assembly cavity 1e is formed within the bottom shell 11. The cover plate 12 is mounted on the housing 1 and closes the open end of the assembly cavity 1e. The bottom shell 11 includes an end cap and side walls. The side walls surround the edge of the end cap. The end cap defines the bottom wall of the assembly cavity 1e, and the side walls define the side walls of the assembly cavity 1e. All valve ports 1a (e.g., the first inlet 111, the second inlet 112, and all outlets 1c) are formed on the end cap to facilitate communication between the switching flow channel 2a of the valve core 2 and the valve ports 1a. Optionally, the cover plate 12 has fixing holes (e.g., self-tapping screw holes) to facilitate fixing the drive component 5. Optionally, the bottom shell 11 is provided with reinforcing ribs and mounting holes to improve the structural strength of the bottom shell 11 and to connect and fix the multi-way valve 100 to corresponding components (e.g., an integrated system) through the mounting holes.

[0134] Optionally, the number of outlets 1c is three or more, and the number of outlets 1c is greater than the number of inlets 1b, so that the multi-way valve 100 can have more connection states and can better adapt to the usage requirements.

[0135] In some embodiments, combined with Figure 1 and Figure 16Multiple outlets 1c include a first outlet 113, a second outlet 114, and a third outlet 115 spaced circumferentially along the valve core 2. The first outlet 113 is adjacent to the first inlet 111 and located on the side of the first inlet 111 furthest from the second inlet 112; therefore, no other valve port 1a is provided between the first outlet 113 and the first inlet 111. The second outlet 114 is adjacent to the second inlet 112 and located on the side of the second inlet 112 furthest from the first inlet 111; therefore, no other valve port 1a is provided between the second outlet 114 and the second inlet 112. a. The third outlet 115 is located between the first outlet 113 and the second outlet 114; the third switching channel 23 includes a first channel section 231, a second channel section 232 and a third channel section 233. The third channel section 233 connects the first channel section 231 and the second channel section 232. In the circumferential direction of the valve core 2, the first channel section 231 and the second channel section 232 are respectively spaced between the first switching channel 21 and the second switching channel 22 and are arranged opposite to each other in the radial direction of the valve core 2. The circumferential length of the first channel section 231 is greater than the length of the second channel section 232.

[0136] In the first mode, the first inlet 111 is connected to the first outlet 113 or the second outlet 114 through either the first switching channel 21 or the second switching channel 22, and the first inlet 111 is connected to the third outlet 115 through the third switching channel 23. Thus, the first mode can have at least three first connection states. In the second mode, the other of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel segment 231 (at this time, the other of the first inlet 111 and the second inlet 112 and the corresponding outlet 1c can both be set opposite to the first channel segment 231), or the other of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel segment 231 and the second channel segment 232 (at this time, the other of the first inlet 111 and the second inlet 112 can be set opposite to the second channel segment 232, and the corresponding outlet 1c can be set opposite to the first channel segment 231). This facilitates the enrichment of the connection states of the multi-way valve 100, and as the valve core 2 rotates, the multi-way valve 100 can switch between multiple connection states to realize the switching connection function of the multi-way valve 100.

[0137] For example, combining Figure 1 and Figures 8-15The housing 1 has a first inlet 111, a second inlet 112, a first outlet 113, a second outlet 114, and a third outlet 115 formed at one axial end. The first outlet 113, the second outlet 114, and the third outlet 115 are arranged equidistantly along the circumference of the valve core 2, and the centers of the first inlet 111, the second inlet 112, the first outlet 113, the second outlet 114, and the third outlet 115 are all located on the same cylindrical surface. The circumferential distance between the first inlet 111 and the second inlet 112 is less than the circumferential distance between the second outlet 114 and the third outlet 115. The circumferential distance between the first inlet 111 and the second inlet 112 is equal to the circumferential distance between the first inlet 111 and the first outlet 113, and is also equal to the circumferential distance between the second inlet 112 and the second outlet 114. The valve core 2 has a first switching flow channel 21, a second switching flow channel 22, and a third switching flow channel 23. The first switching flow channel 21 and the second switching flow channel 22 extend along the circumference of the valve core 2 and have equal extension lengths.

[0138] In the first mode, the first inlet 111 and the second inlet 112 can be connected to the first outlet 113 or the second outlet 114 through either the first switching channel 21 or the second switching channel 22; or, the first inlet 111 and the second inlet 112 are both connected to the first channel section 231, the third outlet 115 is connected to the second channel section 232, and the third channel section 233 connects the first channel section 231 and the second channel section 232, then the first inlet 111 and the second inlet 112 are connected to the third outlet 115 through the third switching channel 23. Thus, in the first mode, the multi-way valve 100 has three first connection states, and as the valve core 2 rotates, one of the first switching channel 21, the second switching channel 22, and the third switching channel 23 connects two inlets 1b (the first inlet 111 and the second inlet 112) and the corresponding outlet 1c, so as to realize the switching of the multi-way valve 100 between the three first connection states.

[0139] In the second mode, the first inlet 111 and the first outlet 113 are connected through the first switching channel 21, and the second inlet 112 and the second outlet 114 are connected through the first channel segment 231, that is, the second inlet 112 and the second outlet 114 are connected through the third switching channel 23; or, the first inlet 111 and the first outlet 113 are connected through the first channel segment 231, that is, the first inlet 111 and the first outlet 113 are connected through the third switching channel 23, and the second inlet 112 and the second outlet 114 are connected through the second switching channel 22; or, the first inlet 111... 1. The first outlet 113 is connected to the second switching channel 22, the third outlet 115 is connected to the first channel section 231, and the second inlet 112 is connected to the second channel section 232, that is, the second inlet 112 and the third outlet 115 are connected through the third switching channel 23; or, the second inlet 112 and the second outlet 114 are connected through the first switching channel 21, the third outlet 115 is connected to the first channel section 231, and the first inlet 111 is connected to the second channel section 232, that is, the first inlet 111 and the third outlet 115 are connected through the third switching channel 23. Thus, in the second mode, the multi-way valve 100 has three second connection states, and as the valve core 2 rotates, two of the first switching channel 21, the second switching channel 22, and the third switching channel 23 are respectively connected to one of the two inlets 1b (the first inlet 111 and the second inlet 112) and the corresponding outlet 1c, so as to realize the switching of the multi-way valve 100 between the three second connection states.

[0140] Of course, as the valve core 2 rotates, the multi-way valve 100 can switch between three first connection states and three second connection states to realize the switching connection function of the multi-way valve 100.

[0141] Combination Figures 8-15On a plane perpendicular to the rotation axis of valve core 2, when valve core 2 rotates to a certain angle position, the orthographic projection of the first switching channel 21 and the orthographic projection of the second switching channel 22 can cover the projections of three valve ports 1a that are sequentially adjacent and circumferentially equidistant (e.g., covering the first inlet 111, the second inlet 112 and the first outlet 113, or covering the first inlet 111, the second inlet 112 and the second outlet 114, etc.). The orthographic projection of the first channel segment 231 can cover the orthographic projections of any two adjacent valve ports 1a that are circumferentially equidistant (e.g., covering the first inlet 111 and the second inlet 112, or covering the first inlet 111 and the first outlet 113, or the second inlet 112 and the second outlet 114, etc.). The orthographic projection of the second channel segment 232 can cover the orthographic projection of one valve port 1a (e.g., covering the third outlet 115, covering the second outlet 114, covering the second inlet 112, covering the first inlet 111, or covering the first outlet 113). This allows the corresponding switching channel 2a to connect two or three valve ports 1a, enabling the multi-way valve 100 to have multiple connection states.

[0142] As can be seen, on the plane perpendicular to the rotation axis of the valve core 22, with the orthographic projection of the rotation axis of the valve core 22 as the center, the central angle corresponding to any two adjacent centers of the first outlet 113, the first inlet 111, the second inlet 112 and the second outlet 114 is 40°, and the central angle corresponding to any two adjacent centers of the first outlet 113, the second outlet 114 and the third outlet 115 is 120°.

[0143] In some embodiments of this application, combined with Figure 3 and Figure 13 As shown, the housing 1 (e.g., cover plate 12) and the valve core 2 are respectively provided with stop ribs 2d, so that the stop ribs 2d on the housing 1 and the stop ribs 2d on the valve core 2 are constructed into an end-stop structure, which can be used as the starting position when the valve core 2 rotates. That is, the angle at which the valve core 22 rotates to switch the multi-way valve 100 to the corresponding first connection state or the corresponding second connection state is referenced to the above starting position. That is, when the stop ribs 2d of the valve core 2 abuts against the single-point rib of the housing 11, the valve core 2 is at the 0° position, which makes it easy to switch the multi-way valve 100 to different connection states by driving the valve core 2 to rotate the corresponding angle, so as to accurately adjust the connection state of the multi-way valve 100.

[0144] In the first mode, the multi-way valve 100 has three first connection states, in the first first connection state, such as... Figure 8 and Figure 9 As shown, the first inlet 111, the second inlet 112, and the second outlet 114 are connected, while the first outlet 113 and the third outlet 115 are closed. At this time, the valve core 2 rotates clockwise to 5° or 165°; in the second first connected state, as... Figure 10 and Figure 11 As shown, the first inlet 111, the second inlet 112, and the first outlet 113 are connected, while the second outlet 114 and the third outlet 115 are closed. At this time, the valve core 2 rotates to 205°. In the third first connected state, as shown... Figure 12 As shown, the first inlet 111, the second inlet 112 and the third outlet 115 are connected, the first outlet 113 and the second outlet 114 are closed, and the valve core 2 rotates to 285°.

[0145] In the second mode, the multi-way valve 100 has three second connection states. In the first second connection state, such as... Figure 14 As shown, the first inlet 111 is connected to the third outlet 115, the second inlet 112 is connected to the second outlet 114, and the first outlet 113 is closed. At this time, the valve core 2 rotates to 125°. In the second connected state, as shown... Figure 13 As shown, the first inlet 111 is connected to the first outlet 113, the second inlet 112 is connected to the third outlet 115, and the second outlet 114 is closed. At this time, the valve core 2 rotates to 85°; in the third second connection state, as... Figure 15 As shown, the first inlet 111 is connected to the first outlet 113, the second inlet 112 is connected to the second outlet 114, and the third outlet 115 is closed. At this time, the valve core 2 rotates to 245°.

[0146] In some embodiments of this application, combined with Figure 5 and Figure 6 The multi-way valve 100 also includes a first sealing element 3. The first sealing element 3 is disposed at multiple valve ports 1a and located between the housing 1 and the valve core 2. The first sealing element 3 is provided with multiple clearance holes 31. Each clearance hole 31 has a limiting protrusion 32 formed around its periphery. Each valve port 1a has a first mating groove 1d formed around its outer periphery. The multiple limiting protrusions 32 are respectively sealed and fitted into the multiple first mating grooves 1d. The other parts of the first sealing element 3, except for the clearance holes 31, separate the valve core 2 from the housing 1.

[0147] Optionally, the first seal 3 may be a rubber component or the like.

[0148] For example, combining Figures 5-6 and Figure 16The first sealing member 3 has five clearance holes 31 arranged sequentially and spaced apart along the circumference of the valve core 2. Each clearance hole 31 has a limiting protrusion 32 on the side of its periphery facing the housing 1. The limiting protrusion 32 is formed as a raised annular structure. Five valve ports 1a are formed on one end face of the housing 1. The five valve ports 1a are a first inlet 111, a second inlet 112 and three outlets 1c, respectively. A first mating groove 1d is formed around the outer periphery of each valve port 1a. The five limiting protrusions 32 correspond one-to-one with the five valve ports 1a. When the first sealing member 3 is located between the housing 1 and the valve core 2, each limiting protrusion 32 of the first sealing member 3 seals with the corresponding first mating groove 1d to achieve a seal between the housing 1 and the valve core 2, thereby improving the sealing performance between the valve core 2 and the housing 1.

[0149] Optionally, the first seal 3 is interference-fitted between the valve core 2 and the housing 1, which helps to further improve the sealing performance between the valve core 2 and the first seal 3, thereby improving the sealing performance between the valve core 2 and the housing 1.

[0150] Optionally, in the axial direction of the valve core 2, the periphery of the open end of the switching channel 2a has a sealing rib 2e. The sealing rib 2e is arranged around the open end of the switching channel 2a. The sealing rib 2e is interference-fitted with the first seal 3, which can further improve the sealing performance between the valve core 2 and the first seal 3.

[0151] In the above technical solution, by setting a first sealing element 3 between the housing 1 and the valve core 2, the sealing between the housing 1 and the valve core 2 can be improved, that is, dynamic sealing is achieved during the rotation of the valve core 2 relative to the housing 1, and static sealing is achieved when the multi-way valve 100 is in a certain connected state. Secondly, a limiting protrusion 32 is formed around the periphery of each clearance hole 31. Each limiting protrusion 32 is sealed and engaged with the first mating groove 1d at the corresponding valve port 1a, which can further improve the sealing between the first sealing element 3 and the housing 1, that is, the sealing of the communication channel between the clearance hole 31 and the valve port 1a. At the same time, the sealing and engagement of the limiting protrusion 32 with the first mating groove 1d can restrict the first sealing element 3 from rotating with the valve core 2, and to a certain extent avoid gaps between the first sealing element 3 and the housing 1 or between the first sealing element 3 and the valve core 2, which is beneficial to improving the sealing performance between the housing 1 and the valve core 2.

[0152] Optionally, combined Figure 6 and Figure 7 Each valve port 1a has a third mating groove formed around the valve port 1a on the outer periphery facing away from the valve core 2. The multi-way valve 100 also includes a third sealing element 6, with multiple third sealing elements 6 corresponding to multiple third mating grooves to achieve sealing when the multi-way valve 100 is mated with other structures such as flanges.

[0153] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the multi-way valve 100 also includes a second sealing element 4, the valve core 2 has a pivot shaft 24, the inner wall of the housing 1 has an annular mating rib 13, the second sealing element 4 is disposed between the pivot shaft 24 and the mating rib 13, the valve core 2 also has a second mating groove 2b arranged around the pivot shaft 24, and the mating rib 13 is mated to the inner side of the outer peripheral wall of the second mating groove 2b.

[0154] For example, combining Figure 5 and Figure 6 The housing 1 includes a bottom shell 11 and a cover plate 12. An open assembly cavity 1e is formed inside the bottom shell 11. The valve core 2 is rotatably disposed in the assembly cavity 1e. The cover plate 12 closes the open end of the assembly cavity 1e. The valve core 2 has a pivot shaft 24. The end of the pivot shaft 24 is formed into a spline structure. A drive member 5 is also installed on the cover plate 12. The output end of the drive member 5 is connected to the spline structure of the valve core 2, so that the drive member 5 can drive the valve core 2 to rotate around its own rotation axis. The other end of the pivot shaft 24 abuts against the bottom wall of the assembly cavity 1e, improving the rotational stability of the valve core 2.

[0155] The cover plate 12 has an annular mating rib 13 on the side facing the bottom shell 11, and the valve core 2 has a pivot shaft 24 on the side facing the cover plate 12. The valve core 2 also has a second mating groove 2b arranged around the pivot shaft 24. When the cover plate 12 is mated with the bottom shell 11, the second sealing member 4 is disposed between the pivot shaft 24 and the mating rib 13. The mating rib 13 is located in the second mating groove 2b, and the mating rib 13 on both sides of the valve core 2 in the radial direction is mated with the inner side of the outer peripheral wall of the second mating groove 2b and the outer peripheral wall of the second sealing member 4, respectively, so as to achieve dynamic sealing between the valve core 2 and the cover plate 12 and ensure the sealing performance of the multi-way valve 100.

[0156] Optionally, a welding rib is formed on the edge of the open end of the bottom shell 11. The welding rib is used to mate with the welding groove of the cover plate 12, which facilitates the welding of the bottom shell 11 and the cover plate 12 together, so that the bottom shell 11 and the cover plate 12 have high sealing performance and compressive strength. In the radial direction of the valve core 2, the width of the welding groove is greater than the width of the welding rib, for example, the width of the welding rib is 1.3 mm and the width of the welding groove is 2.5 mm.

[0157] Optionally, the bottom shell 11 is made of light-absorbing material and the cover plate 12 is made of light-transmitting material, so that the bottom shell 11 and the cover plate 12 can be laser welded together. For example, the bottom shell 11 is injection molded from light-absorbing material and the cover plate 12 is injection molded from light-transmitting material.

[0158] In the above technical solution, by setting the second sealing element 4 between the pivot shaft 24 and the mating rib 13, and the mating rib 13 mating with the inner side of the outer peripheral wall of the second mating groove 2b, the sealing between the valve core 2 and the cover plate 12 can be achieved, ensuring the sealing performance of the multi-way valve 100, and at the same time facilitating the reliable limiting of the second sealing element 4.

[0159] In some embodiments of this application, combined with Figure 5 and Figure 6 The bottom wall of the second mating groove 2b is provided with an annular mating protrusion 2c. The mating protrusion 2c is spaced apart from the outer peripheral wall of the second mating groove 2b and is mated to the inner side of the mating rib 13. The mating protrusion 2c is used to restrict the movement of the second seal 4 in the axial direction of the valve core 2.

[0160] In the above technical solution, by setting the mating protrusion 2c to restrict the movement of the second sealing element 4 in the axial direction of the valve core 2, the sealing between the valve core 2 and the cover plate 12 can be prevented to a certain extent due to the rotation of the valve core 2, which is conducive to improving the reliability of the seal between the valve core 2 and the cover plate 12.

[0161] Thirdly, embodiments of this application provide a thermal management system 200, including the multi-way valve 100 of the second aspect embodiment described above.

[0162] In the above technical solution, by adopting the multi-way valve 100, the layout of the thermal management system 200 can be simplified, which is conducive to realizing the integrated layout of the thermal management system 200.

[0163] In some embodiments of this application, such as Figure 1 and Figures 8-16 As shown, the multiple outlets 1c include a first outlet 113, a second outlet 114, and a third outlet 115 spaced apart circumferentially along the valve core 2. The first outlet 113 is adjacent to the first inlet 111 and located on the side of the first inlet 111 away from the second inlet 112. The second outlet 114 is adjacent to the second inlet 112 and located on the side of the second inlet 112 away from the first inlet 111. The third outlet 115 is located between the first outlet 113 and the second outlet 114. The third switching flow channel 23 includes a first flow channel section 231, a second flow channel section 232, and a third flow channel section 233. The third flow channel section 233 connects the first flow channel section 231 and the second flow channel section 232. In the circumferential direction of the valve core 2, the first flow channel section 231 and the second flow channel section 232 are respectively spaced apart between the first switching flow channel 21 and the second switching flow channel 22 and are arranged opposite each other in the radial direction of the valve core 2. The circumferential length of the first flow channel section 231 is greater than the length of the second flow channel section 232.

[0164] In the first mode, the first inlet 111 is connected to the first outlet 113 or the second outlet 114 through either the first switching channel 21 or the second switching channel 22, and the first inlet 111 is connected to the third outlet 115 through the third switching channel 23; in the second mode, the other of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel segment 231, or the other of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel segment 231 and the second channel segment 232.

[0165] The thermal management system 200 further includes a first flow path 101, a second flow path 102, a third flow path 103, a fourth flow path 104, a fifth flow path 105, a first temperature regulating element 106 connected in series to the third flow path 103, and a second temperature regulating element 107 connected in series to the fourth flow path 104. The temperature regulating capabilities of the first temperature regulating element 106 and the second temperature regulating element 107 are different. The first flow path 101 is used to regulate the temperature of the motor 109, and the second flow path 102 is used to regulate the temperature of the battery pack 110. The first inlet 111 is connected to the downstream end of the second flow path 102. The second inlet 112 is connected to the downstream end of the first flow path 101, the first outlet 113 is connected to the upstream end of the fifth flow path 105, the second outlet 114 is connected to the upstream end of the fourth flow path 104, and the third outlet 115 is connected to the upstream end of the third flow path 103. In the first mode, any one of the first outlet 113, the second outlet 114, and the third outlet 115 is connected to the first inlet 111. In the second mode, any two of the first outlet 113, the second outlet 114, and the third outlet 115 are respectively connected to the first inlet 111 and the second inlet 112.

[0166] For example, combining Figures 8-15 and Figure 17 The thermal management system 200 also includes three switching components 108, each configured as a three-way valve. The three three-way valves are a first three-way valve, a second three-way valve, and a third three-way valve. The first three-way valve connects to the downstream end of the fourth flow path 104, connects to the downstream end of the third flow path 103 via the second three-way valve, and connects to the upstream end of the second flow path 102 via both the second and third three-way valves. The second three-way valve connects to the downstream end of the first three-way valve, the third three-way valve, and the third flow path 103. The third three-way valve connects to the downstream end of the second three-way valve, the fifth flow path 105, and the upstream end of the second flow path 102. Water pumps are connected in series on the first flow path 101 and the second flow path 102, respectively. The first temperature regulating element 106 is a refrigeration device, such as an evaporator with an internal refrigerant flow path, and the second temperature regulating element 107 is an air-cooled radiator.

[0167] In the first first connection state, both the first inlet 111 and the second inlet 112 are connected to the first outlet 113 through either the first switching channel 21 or the second switching channel 22. In this case, the first flow path 101 and the fifth flow path 105 form a loop, and the second flow path 102 and the fifth flow path 105 also form a loop. In the second first connection state, both the first inlet 111 and the second inlet 112 are connected to the second outlet 114 through either the first switching channel 21 or the second switching channel 22. In this case, the first flow path 101 and the fourth flow path 104 form a loop. In the first loop, the second flow path 102 and the fourth flow path 104 form a loop, and the second temperature regulating element 107 operates to regulate the temperature of the battery pack 110 and the motor 109; in the third first connection state, the first inlet 111 and the second inlet 112 are both connected to the third outlet 115 through the third switching flow channel 23, then the first flow path 101 and the third flow path 103 form a loop, the second flow path 102 and the third flow path 103 form a loop, and the first temperature regulating element 106 operates to regulate the temperature of the battery pack 110 and the motor 109.

[0168] In the first second connection state, the first inlet 111 is connected to the first outlet 113 through the first switching channel 21, and the second inlet 112 is connected to the second outlet 114 through the third switching channel 23; or, the first inlet 111 is connected to the first outlet 113 through the third switching channel 23, and the second inlet 112 is connected to the second outlet 114 through the second switching channel 22. In this case, the first flow path 101 and the fourth flow path 104 form a loop, and the second flow path 102 and the fifth flow path 105 form a loop. The second temperature regulating element 107 operates to regulate the temperature of the motor 109. In the second second connection state, the first inlet 111 is connected to the third outlet 115 through the third switching channel 23, and the second inlet 112... When the first switching channel 21 is connected to the second outlet 114, the second flow path 102 and the third flow path 103 form a loop, and the first flow path 101 and the fourth flow path 104 form a loop. The first temperature regulating element 106 and the second temperature regulating element 107 work to regulate the temperature of the motor 109 and the battery pack 110 respectively. In the third second connection state, the second inlet 112 is connected to the third outlet 115 through the third switching channel 23, and the first inlet 111 is connected to the first outlet 113 through the second switching channel 22. Then the first flow path 101 and the third flow path 103 form a loop, and the second flow path 102 and the fifth flow path 105 form a loop. The second temperature regulating element 107 works to regulate the temperature of the motor 109.

[0169] Therefore, by adjusting the multi-way valve 100 to switch between multiple first connection states in the first mode and multiple second connection states in the second mode, the thermal management system 200 can be in different flow path connection states to adapt to the application requirements of the thermal management system 200 and improve the practicality and applicability of the thermal management system 200.

[0170] In the above technical solution, by adjusting the multi-way valve 100 to switch between multiple first connection states in the first mode and multiple second connection states in the second mode, the thermal management system 200 can be in different flow path connection states to adapt to the application requirements of the thermal management system 200 and improve the practicality and applicability of the thermal management system 200.
