[0050] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0051] Reference below Figures 1-9 A multi-way valve 200 according to an embodiment of the present invention will be described.

[0052] Combine Figures 1 to 3According to an embodiment of the present invention, a multi-way valve 200 includes a housing 210 and a valve core 100. A mounting cavity 215 is formed within the housing 210. A plurality of circumferentially spaced valve port rows 211 are formed on the circumferential wall of the mounting cavity 215. Each valve port row 211 includes a plurality of axially spaced valve ports 2111. The valve core 100 is formed with a plurality of circumferentially spaced flow channel groups. The valve core 100 is rotatably mounted within the mounting cavity 215 to switch the plurality of flow channel groups between corresponding valve port rows 211 on the housing 210. As can be seen, the flow channel inlets and flow channel outlets of the flow channel groups are formed on the outer circumferential wall of the valve core 100, so that the flow channel inlets communicate with corresponding valve ports 2111, and the flow channel outlets communicate with corresponding valve ports 2111. Rotation of the valve core 100 allows any of the plurality of flow channel groups to communicate with the corresponding valve port row 211, thereby switching the multi-way valve 200 to a corresponding communication mode.

[0053] For example, an installation cavity 215 extending in the axial direction is formed in the shell 210, and one end of the shell 210 in the axial direction is open. The valve core 100 can be installed in the installation cavity 215 through the open end of the shell 210, and the valve core 100 can be driven to rotate in the installation cavity 215.

[0054] Exemplarily, the valve port 2111 is arranged to pass through the peripheral wall of the installation cavity 215 in the radial direction (it can also be understood that the valve port 2111 passes through the shell 210 in the radial direction), and the valve port 2111 is used to connect with the external pipeline on the side away from the valve core 100 in the radial direction. When the valve port column 211 is opposite to the flow channel group in the radial direction, the valve port column 211 is connected to the flow channel group, and the fluid can flow from the external pipeline into the flow channel group through the valve port 2111; by driving the valve core 100 to rotate in the installation cavity 215, so that different flow channel groups can be respectively opposite to the valve port column 211, thereby switching the flow channel group connected to the valve port column 211, thereby realizing multiple connection modes of the multi-way valve 200.

[0055] Among them, at least one group of flow channel groups includes at least one conducting structure 110, and the number of flow channel groups including the conducting structure 110 is less than or equal to the total number of flow channel groups; each conducting structure 110 is used to connect the corresponding valve port 2111 of the same valve port column 211, and each conducting structure 110 includes a first conducting channel 111 and a second conducting channel 112 arranged at intervals, the second conducting channel 112 is used to connect two adjacent valve ports 2111, the first conducting channel 111 is used to connect the other two valve ports 2111 separated by at least the two valve ports 2111 connected by the second conducting channel 112, and the two valve ports 2111 connected to the first conducting channel 111 and the two valve ports 2111 connected to the second conducting channel 112 belong to the same valve port column 211.

[0056] Specifically, the first conducting channel 111 and the second conducting channel 112 are arranged at intervals to ensure the independence between the first conducting channel 111 and the second conducting channel 112. The fluid can flow into the first conducting channel 111 or the second conducting channel 112 separately, so that the valve core 100 can define different flow paths for the fluid to flow, which is convenient for realizing different connectivity states of the multi-way valve 200, that is, realizing different connectivity modes of the multi-way valve 200.

[0057] The second conducting channel 112 is used to communicate with two valve ports 2111 arranged adjacent to each other in the axial direction in the same valve port row 211. The fluid flows into the second conducting channel 112 through one of the two valve ports 2111 arranged adjacent to each other in the axial direction, and flows out of the second conducting channel 112 through the other valve port 2111 of the above two valve ports 2111. The first conducting channel 111 is used to communicate with the valve ports 2111 located on both sides of the two valve ports 2111 connected to the second conducting channel 112 in the axial direction. The fluid can flow into the first conducting channel 111 through one of the two valve ports 2111 and flow out of the first conducting channel 111 through the other valve port 2111.

[0058] For example, a valve port array 211 corresponding to the conductive structure 110 may include five valve ports 2111 spaced apart in the axial direction, and the five valve ports 2111 are sequentially named as the first port, the second port, the third port, the fourth port, and the fifth port along the axial direction. The following configurations may be employed: 1. The second conductive channel 112 may connect the second port and the third port, and the first conductive channel 111 may connect the first port and the fourth port, or the first conductive channel 111 may connect the first port and the fifth port; 2. The second conductive channel 112 connects the third port and the fourth port, and the first conductive channel 111 connects the second port and the fifth port, or the first conductive channel 111 connects the first port and the fifth port. Of course, the valve port array 211 corresponding to the conductive structure 110 may also be configured to include four valve ports 2111.

[0059] Alternatively, for a single flow channel group including a conductive structure 110, the flow channel group may include multiple conductive structures 110. The multiple conductive structures 110 may be spaced circumferentially so that the multiple conductive structures 110 are adapted to correspond one-to-one with multiple valve port rows 211, and each conductive structure 110 may be connected to a valve port 2111 corresponding to the same valve port row 211, thereby achieving a multi-way mode of the multi-way valve 200, in which different conductive structures 110 correspond to different valve port rows 211. Alternatively, the multiple conductive structures 110 of the flow channel group may be spaced axially so that the multiple conductive structures 110 are adapted to correspond to the same valve port row 211. Alternatively, the multiple conductive structures 110 of the flow channel group may be arranged in multiple rows and columns circumferentially and axially. Of course, the flow channel group may also include a single conductive structure 110.

[0060] It is understandable that when at least two of the multiple flow channel groups respectively include the conducting structure 110 , the number and arrangement of the conducting structures 110 of the at least two flow channel groups may be the same or different.

[0061] In the related art, the multi-way valve can realize fewer connection modes and cannot meet the use requirements, especially when the multi-way valve is used in a thermal management system with a complex structure. In order to ensure that the thermal management system can realize multiple heat exchange modes, it is necessary to set up multiple multi-way valves in the thermal management system to switch the connection status of different pipelines of the thermal management system, resulting in the thermal management system occupying a large space, being inconvenient to control and having high production costs.

[0062] The present application improves the space utilization of the valve core 100 and increases the flow channel structure on the valve core 100 by arranging multiple groups of flow channel groups spaced apart along the circumferential direction on the valve core 100, wherein at least one group of flow channel groups includes at least one conducting structure 110, that is, the structures of the multiple flow channel groups are different, and multiple columns of valve port columns 211 are formed on the shell 210. By switching the valve port columns 211 with the multiple groups of flow channel groups, multiple communication modes of the multi-way valve 200 are realized. For the same valve port column 211, by arranging the conducting structure 110, the second conducting flow channel 112 Two adjacent valve ports 2111 can be connected, and the first conducting channel 111 can be connected to the two valve ports 2111 separated by the above-mentioned two valve ports 2111, so that different valve ports 2111 of the same valve port column 211 are connected, thereby increasing the applicable scenarios of the multi-way valve 200 and improving the performance of the multi-way valve 200. When the multi-way valve 200 is applied to the thermal management system 300, it is beneficial to reduce the arrangement of the valve body in the thermal management system 300, thereby facilitating the weight reduction and cost reduction of the thermal management system 300, and facilitating the miniaturization design of the thermal management system 300.

[0063] Reference Figure 1 In the description of this application, "axial" refers to the axial direction of the valve core 100, that is, the extension direction of the central axis L of the valve core 100, "circumferential" refers to the circumference of the valve core 100, that is, the direction around the central axis L of the valve core 100, and "radial" refers to the radial direction of the valve core 100, that is, the direction passing through the central axis L of the valve core 100 in the radial plane. "Axial", "circumferential" and "radial" are perpendicular to each other.

[0064] Combine Figure 8 indivual Figure 9 In some embodiments of the present invention, a portion of the first conducting channel 111 is located radially inside a portion of the second conducting channel 112 , and the portion of the first conducting channel 111 is radially opposite to the portion of the second conducting channel 112 .

[0065] For example, the first conducting channel 111 includes a first inlet 11, a first outlet 12, and a first channel section 13 connected between the first inlet 11 and the first outlet 12. The second conducting channel 112 has a second inlet 21, a second outlet 22, and a second channel section 23 connected between the second inlet 21 and the second outlet 22. The first inlet 11, the first outlet 12, the second inlet 21 and the second outlet 22 are all formed on the outer peripheral wall of the valve core 100.

[0066] Among them, the first inlet 11 and the first outlet 12 are arranged at intervals along the axial direction, and the first flow channel section 13 is formed in the valve core 100 and connects the first inlet 11 and the first outlet 12. The first inlet 11 and the first outlet 12 are suitable for corresponding to two valve ports 2111 in the same valve port column 211 that are spaced apart by other valve ports 2111. The fluid can flow into the first flow channel section 13 through the first inlet 11 and flow out of the first flow channel section 13 through the first outlet 12.

[0067] The second flow channel section 23 is located on the side of the first flow channel section 13 away from the central axis L of the valve core 100 in the radial direction of the valve core 100, that is, the second flow channel section 23 is located radially outside the first flow channel section 13, and the second flow channel section 23 connects the second inlet 21 and the second outlet 22. The second inlet 21 and the second outlet 22 are respectively connected to two adjacent valve ports 2111 in the same valve port column 211. The fluid can flow into the second flow channel section 23 through the second inlet 21 and flow out of the second flow channel section 23 through the second outlet 22.

[0068] In the radial direction of the valve core 100, the first flow channel section 13 is located radially inside the second flow channel section 23 and is arranged opposite to the second flow channel section 23 in the radial direction, so that an inner and outer double-layer flow channel is formed on the valve core 100, while increasing the flow path of the fluid and reasonably allocating the space inside the valve core 100, thereby improving the space utilization of the valve core 100, which is beneficial to reducing the circumferential occupied space of the conducting structure 110, and is beneficial to reducing the complexity of the structural design of the valve core 100. At the same time, the miniaturization design of the valve core 100 can be realized, which is beneficial to reducing the volume of the multi-way valve 200.

[0069] It can be understood that three or more layers of inner and outer flow channels can be formed on the valve core 100 along its radial direction. For example, the conducting structure 110 also includes a sixth conducting flow channel, and the sixth conducting flow channel has a third flow channel section located radially inside the first flow channel section 13 and radially opposite to the first flow channel section 13. At this time, the first flow channel section 13, the second flow channel section 23 and the third flow channel section can form an inner and outer three-layer flow channel on the valve core 100.

[0070] Combine Figure 8 and Figure 9In some embodiments of the present invention, the distance between the opposing walls of the first conducting channel 111 and the second conducting channel 112 is greater than or equal to 1.5 mm.

[0071] Specifically, the distance between the side wall of the first conducting channel 111 close to the second conducting channel 112 and the side wall of the second conducting channel 112 close to the first conducting channel 111 is greater than or equal to 1.5 mm, so as to improve the structural strength of the conducting structure 110 and prevent the conducting structure 110 from being damaged due to excessive pressure when the fluid flows into the conducting structure 110. At the same time, the thermal resistance between the first conducting channel 111 and the second conducting channel 112 can be increased, which is conducive to reducing the heat exchange caused by the different temperatures of the fluids flowing into the first conducting channel 111 and the second conducting channel 112 at the same time.

[0072] Reference Figure 8 In some embodiments of the present invention, a first groove 120 is formed on the valve core 100, and the first groove 120 is open toward the radial outside of the valve core 100. A first partition 121 is provided in the first groove 120, and the first partition 121 divides the first groove 120 into a first conducting flow channel 111 and a second conducting flow channel 112. The first flow channel section 13 and the second flow channel section 23 are respectively located on both sides of the first partition 121 in the radial direction of the valve core 100.

[0073] Specifically, the first groove 120 is formed on the outer peripheral wall of the valve core 100, and the first groove 120 is recessed along the radial direction of the valve core 100 close to the direction of the center axis L of the valve core 100, and the first separator 121 is arranged in the first groove 120 and separates the first groove 120, so that the first conducting flow channel 111 and the second conducting flow channel 112 arranged at intervals are formed in the first groove 120, and the first flow channel section 13 and the second flow channel section 23 are arranged at intervals on both sides of the radial direction of the first separator 121, so that the first flow channel section 13 and the second flow channel section 23 form a double-layer flow channel on the valve core 100. By setting the first separator 121, it is beneficial to simplify the molding of the first conducting flow channel 111 and the second conducting flow channel 112, thereby improving the processing convenience of the valve core 100.

[0074] Combine Figure 8 and Figure 9 In some embodiments of the present invention, the thickness t of the first separator 121 satisfies the following relationship: t≥1.5 mm.

[0075] It should be noted that “the thickness of the first partition 121 ” may be understood as the distance between the first conducting channel 111 and the second conducting channel 112 .

[0076] By making the thickness t of the first partition 121 ≥ 1.5 mm to improve the structural strength of the first partition 121, it is beneficial to prevent the first partition 121 from being damaged due to excessive pressure when the fluid flows into the conductive structure 110, thereby preventing damage to the conductive structure 110. At the same time, the heat insulation effect of the first partition 121 can be improved, which is beneficial to reducing the heat exchange amount caused by the fluid flowing into the first conductive channel 111 and the second conductive channel 112 due to different temperatures.

[0077] like Figure 8 As shown, in some embodiments of the present invention, the first separator 121 includes two first plate bodies 1211 spaced apart in the axial direction of the valve core 100 and a second plate body 1212 connected between the two first plate bodies 1211, the first flow channel section 13 is located on the radial inner side of the second plate body 1212, the second flow channel section 23 is located on the radial inner side of the second plate body 1212, the first inlet 11 and the first outlet 12 are respectively located on the side of the corresponding first plate body 1211 away from the other first plate body 1211, and the second inlet 21 and the second outlet 22 are both located between the two first plate bodies 1211.

[0078] Specifically, the first plate body 1211 extends along the radial direction of the valve core 100 and is connected to the outer peripheral wall of the valve core 100, the two first plate bodies 1211 are arranged at intervals in the axial direction of the valve core 100, and the second plate body 1212 extends along the axial direction of the valve core 100 and is respectively connected to the two first plate bodies 1211, so that the first separator 121 can separate the first groove 120 into the first conducting channel 111 and the second conducting channel 112 arranged at intervals.

[0079] Furthermore, relative to the second flow channel 23, the first flow channel section 13 is arranged relatively close to the center axis L of the valve core 100, and the length of the first flow channel section 13 in the axial direction is greater than or equal to the length of the second flow channel section 23 in the axial direction, so that the first flow channel section 13 is respectively connected to the first inlet 11 and the first outlet 12 located on both sides of the axial direction of the first partition 121.

[0080] Reference Figure 9 In some embodiments of the present invention, the cross-sectional shapes of the first flow channel section 13 and the second flow channel section 23 are both fan-shaped, and the flow areas of the two are the same.

[0081] Exemplarily, the first separator 121 includes two first plate bodies 1211 spaced apart in the axial direction and a second plate body 1212 connected between the two first plate bodies 1211 and extending along the axial direction, and in the axial direction of the valve core 100, the cross-section of the second plate body 1212 is an arc-shaped plate with the positive projection of the central axis L of the valve core 100 as the center of the circle, the second plate body 1212 and the central axis 160 of the valve core 100 define a first flow channel section 13 with a fan-shaped cross section, and the side of the second plate body 1212 facing away from the central axis 160 of the valve core 100 defines a second flow channel section 23 with a fan-shaped cross section.

[0082] For example, the central angles of the first flow channel section 13 and the second flow channel section 23 are the same and are defined as θ. The outer diameter of the valve core 100 is defined as D, the outer diameter of the second plate 1212 is defined as d, the outer diameter of the central axis 160 is defined as d1, and the thickness of the second plate 1212 is defined as t. The cross-sectional area S1 of the first flow channel section 13 is (θ / 360)*π*[(dt) 2 -d1 2 ] / 4, the cross-sectional area S2 of the second flow channel section 23 = (θ / 360)*π*(D 2 -d 2 ) / 4, and S1=S2, so as to reduce the pressure difference between the first conductive flow channel 111 and the second conductive flow channel 112, which is beneficial to reducing the flow resistance of the fluid.

[0083] Combine Figures 3 to 7 In some embodiments of the present invention, at least one of a third conducting channel 130, a fourth conducting channel 140 and a fifth conducting channel 150 is further formed on the valve core 100. The at least one of the third conducting channel 130, the fourth conducting channel 140 and the fifth conducting channel 150 is spaced apart from the conducting structure 110 in the axial or circumferential direction of the valve core 100, and each channel group includes at least one of the conducting structure 110, the third conducting channel 130, the fourth conducting channel 140 and the fifth conducting channel 150.

[0084] For example, the valve core 100 may be formed with a third conducting channel 130 and a conducting structure 110, and the third conducting channel 130 and the conducting structure 110 may be spaced apart in the circumferential or axial direction of the valve core 100; or the valve core 100 may be formed with a conducting structure 110, a third conducting channel 130 and a fifth conducting channel 150, and the third conducting channel 130 and the fifth conducting channel 150 may be spaced apart in the circumferential or axial direction of the valve core 100; the valve core 100 may be formed with a conducting structure 110. 10. The third conducting channel 130, the fourth conducting channel 140 and the fifth conducting channel 150. The third conducting channel 130, the fourth conducting channel 140 and the fifth conducting channel 150 can be spaced apart from the conducting structure 110 in the axial or circumferential direction of the valve core 100, so that the conducting structure 110 and the third conducting channel 130, the fourth conducting channel 140 or the fifth conducting channel 150 are independent of each other, ensuring that multiple independent flow channels can be formed on the valve core 100 to prevent the flow paths of the fluid from crossing in different modes.

[0085] Exemplarily, the structures between multiple flow channel groups can be different, for example: the first group of the multiple flow channel groups can be composed of a plurality of third conducting flow channels 130 arranged at intervals along the axial direction, the second group of the multiple flow channel groups can be composed of a plurality of conducting structures 110 arranged at intervals along the circumferential direction, and the third group of the multiple flow channel groups can be composed of a third conducting flow channel 130, a fourth conducting flow channel 140 and a fifth conducting flow channel 150, so that when different flow channel groups are switched to be connected to the valve port array 211, the connection mode of the multi-way valve 200 can be switched, so that the multi-way valve 200 has multiple different connection modes.

[0086] Combine Figure 4 and Figure 8 The third conducting channel 130 passes through the outer peripheral wall of the valve core 100 to form a first opening 131 extending along the circumferential direction of the valve core 100. A portion of the first opening 131 is formed as an inlet of the third conducting channel 130, and the other portion is formed as an outlet of the third conducting channel 130, so that the third conducting channel 130 is used to connect two adjacent valve ports 2111 of the same valve port row 211.

[0087] For example, the valve core 100 is formed with a second groove 132 that is recessed in the radial direction toward the central axis L of the valve core 100. The second groove 132 is spaced apart from the first groove 120 in the circumferential direction, and a plurality of second partitions 133 spaced apart in the axial direction are provided in the second groove 132. The second partitions 133 extend in the circumferential direction of the valve core 100 and are connected to the groove wall of the second groove 132. The second partitions 133 are used to divide the second groove 132 into a plurality of third partitions extending in the circumferential direction of the valve core 100. The flow channel 130, the third conducting flow channel 130 is open on one side away from the central axis L of the valve core 100 in the radial direction to form a first opening 131 extending along the circumferential direction of the valve core 100, a part of the first opening 131 is formed as the inlet of the third conducting flow channel 130, and the other part of the first opening 131 is formed as the outlet of the third conducting flow channel 130, and the inlet and outlet of the third conducting flow channel 130 can be respectively connected to the valve ports 2111 of two valve port columns 211 adjacent to each other in the circumferential direction in the multiple valve port columns 211.

[0088] For example: three rows of valve ports 211 arranged along the circumferential direction are provided on the shell 210, and the three rows of valve ports 211 are defined as the first row of valve ports, the second row of valve ports and the third row of valve ports, respectively. The second row of valve ports is located between the first row of valve ports and the third row of valve ports in the circumferential direction, and each row of valve ports 211 includes valve ports A, valve ports B and valve ports C arranged along the axial direction, wherein the valve ports A of the first row of valve ports are adjacent to the valve ports A of the second row of valve ports and the valve ports A of the third row of valve ports in the circumferential direction. Similarly, the valve ports B of the three rows of valve ports 211 are adjacent to each other in the circumferential direction, and the valve ports C of the three rows of valve ports 211 are adjacent to each other in the circumferential direction.

[0089] The inlet and outlet of the third conducting channel 130 can respectively connect the A valve ports of the first valve port column and the second valve port column, or the inlet and outlet of the third conducting channel 130 can respectively connect the A valve ports of the second valve port column and the third valve port column. Similarly, the inlet and outlet of the third conducting channel 130 can respectively connect two adjacent B valve ports, or the inlet and outlet of the third conducting channel 130 can respectively connect two adjacent C valve ports, which will not be elaborated here.

[0090] Reference Figure 5 The fourth conducting channel 140 passes through the outer peripheral wall of the valve core 100 to form a second opening 141 extending along the axial direction of the valve core 100. A portion of the second opening 141 is formed as an inlet of the fourth conducting channel 140, and the other portion is formed as an outlet of the fourth conducting channel 140, so that the fourth conducting channel 140 is used to connect two adjacent valve ports 2111 of the same valve port row 211.

[0091] Exemplarily, a third groove 142 is formed on the valve core 100, which is recessed in the radial direction toward the center axis L of the valve core 100. The third groove 142 is spaced apart from the first groove 120 in the circumferential direction. The third groove 142 is provided with third separators 143 spaced apart in the circumferential direction. The third separators 143 extend in the axial direction of the valve core 100 and are connected to the groove wall of the third groove 142. The third separators 143 are used to separate the third groove 142 into a plurality of fourth conducting channels 140 spaced apart in the circumferential direction of the valve core 100.

[0092] Further integration Figure 1 The fourth conducting channel 140 is open on one side away from the central axis L of the valve core 100 in the radial direction to form a second opening 141 extending in the axial direction. A portion of the second opening 141 forms an inlet of the fourth conducting channel 140, and the other portion forms an outlet of the fourth conducting channel 140. The inlet and outlet of the fourth conducting channel 140 can respectively connect two adjacent valve ports 2111 in the same valve port row 211.

[0093] For example: the inlet and outlet of the fourth conducting channel 140 can respectively connect the valve port A and the valve port B in the first column of valve ports; or the inlet and outlet of the fourth conducting channel 140 can respectively connect the valve port B and the valve port C in the first column of valve ports. Similarly, the inlet and outlet of the fourth conducting channel 140 can respectively connect the two adjacent valve ports 2111 in the second column of valve ports, or the inlet and outlet of the fourth conducting channel 140 can respectively connect the two adjacent valve ports 2111 in the third column of valve ports. They will not be elaborated here.

[0094] Combine Figure 5 、 Figure 7 and Figure 8 The fifth conducting channel 150 penetrates the outer peripheral wall of the valve core 100 to form an inlet and an outlet of the fifth conducting channel 150. The inlet and the outlet of the fifth conducting channel 150 are separated by part of the outer peripheral wall of the valve core 100 along the axial or circumferential direction of the valve core 100, so that the fifth conducting channel 150 is used to connect the other two valve ports 2111 separated by at least one valve port 2111.

[0095] Exemplarily, a fourth groove 151 can be formed on the valve core 100, which is recessed in the radial direction toward the center axis L of the valve core 100, and the fourth groove 151 is open to the side away from the center axis L of the valve core 100. A fourth separator 152 is provided on the valve core 100, and the fourth separator 152 is provided at the opening of the fourth groove 151 and is connected to the outer peripheral wall of the valve core 100 to separate the opening of the fourth groove 151 into the inlet and outlet of the fifth guide channel 150, and the inlet and outlet of the fifth guide channel 150 are respectively located on opposite sides of the fourth separator 152.

[0096] Exemplarily, the fifth conducting channel 150 can extend along the circumferential direction of the valve core 100, and the inlet and outlet of the fifth conducting channel 150 can respectively connect the valve ports 2111 corresponding to two rows of valve port rows 211 spaced apart in the circumferential direction. For example, the fifth conducting channel 150 can connect the valve ports A of the first row of valve port rows and the third row of valve port rows.

[0097] Or the fifth conducting channel 150 can extend along the axial direction of the valve core 100, and the inlet and outlet of the fifth conducting channel 150 can be respectively connected to two valve ports 2111 in the same valve port column 211, which are separated by at least one valve port 2111 in the axial direction. For example: the inlet and outlet of the fifth conducting channel 150 can be respectively connected to valve port A and valve port C in the first valve port column.

[0098] Among them, the valve core 100 can be simultaneously provided with a conducting structure 110, a third conducting channel 130, a fourth conducting channel 140 and a fifth conducting channel 150 that are spaced apart from each other, so as to further improve the space utilization on the valve core 100 and increase the channels available for fluid communication. Each channel group includes at least one of the conducting structure 110, the third conducting channel 130, the fourth conducting channel 140 and the fifth conducting channel 150, so that a variety of different channel groups can be formed on the valve core 100, which is conducive to increasing the connection modes that can be achieved by the multi-way valve 200.

[0099] In some embodiments of the present invention, the flow channel group satisfies at least one of the following conditions: Condition A1, a plurality of third conducting flow channels 130 spaced apart along the axial direction of the valve core 100 constitute one of the flow channel groups.

[0100] Specifically, if Figure 4 As shown, multiple third conducting channels 130 are arranged at intervals along the axial direction of the valve core 100 to form one of the multiple channel groups. The inlet and outlet of each third conducting channel 130 are respectively located at its circumferential ends. Each third conducting channel 130 connects the valve ports 2111 corresponding to two adjacent columns of valve port columns 211. When the valve core 100 is driven to rotate until the channel group is opposite to the multiple columns of valve port columns 211, the channel group can connect every two valve ports 2111 adjacent to each other in the circumferential direction to realize a connection mode of the multi-way valve 200.

[0101] Condition A2: A plurality of fourth conducting flow channels 140 spaced apart along the axial direction and / or circumferential direction of the valve core 100 form one flow channel group.

[0102] Optionally, refer to Figure 5When the fourth conducting channel 140 has a relatively small size in the axial direction, a plurality of fourth conducting channels 140 may be arranged at intervals along the circumferential and axial directions of the valve core 100. For example, four fourth conducting channels 140 may be provided, and the four fourth conducting channels 140 may be arranged in a rectangular shape on the outer peripheral wall of the valve core 100 to constitute one of the channel groups. When the valve core 100 is driven to rotate until the channel group is opposite to the multiple valve port columns 211, each fourth conducting channel 140 may connect the two corresponding valve ports 2111 in each valve port column 211, thereby realizing a communication mode of the multi-way valve 200.

[0103] In other examples, the plurality of fourth conducting channels 140 may be spaced apart along the circumferential direction of the valve core 100 ; or the plurality of fourth conducting channels 140 may be spaced apart along the axial direction of the valve core 100 .

[0104] Condition A3: at least one third conducting flow channel 130 and at least one fourth conducting flow channel 140 are spaced apart along the axial direction of the valve core 100 to form one flow channel group.

[0105] For example: Figure 6 As shown, the valve core 100 can be provided with three third conducting channels 130 arranged in sequence along the axial direction and a fourth conducting channel 140. The inlet or outlet of the fourth conducting channel 140 and the third conducting channel 130 are arranged relative to each other in the axial direction to form one of the channel groups. When the valve core 100 is driven to rotate until the channel group is connected to the multiple columns of valve ports 211, each third conducting channel 130 can connect two valve ports 2111 arranged adjacent to each other in the circumferential direction, and at the same time, the fourth conducting channel 140 can connect two valve ports 2111 arranged adjacent to each other in the axial direction to form a connection mode of the multi-way valve 200.

[0106] Of course, it is understandable that the number of the third conducting channel 130 and the fourth conducting channel 140 can be determined according to actual production requirements and is not specifically limited here.

[0107] Condition A4: a plurality of conducting structures 110 spaced apart along the circumference of the valve core 100 form one of the flow channel groups.

[0108] For example, refer to Figure 3The two conducting structures 110 can be arranged at intervals along the circumferential direction of the valve core 100 to form one of the multiple flow channel groups. When the valve core 100 is driven to rotate until the flow channel group is opposite to the multiple valve port columns 211, the first conducting flow channel 111 of each conducting structure 110 can connect the valve ports 2111 located at the axial ends of the same valve port column 211, and the second conducting flow channel 112 can connect two valve ports 2111 located in the middle position of the axial direction and adjacent to each other among the multiple valve ports 2111, so as to form a connection mode of the multi-way valve 200.

[0109] Of course, it is understandable that there may be three, four, etc. conductive structures 110 . The specific number of conductive structures 110 may be determined according to actual production requirements and is not specifically limited here.

[0110] Condition A5: at least one of the third conducting channel 130 and the fourth conducting channel 140 and the fifth conducting channel 150 form one channel group.

[0111] For example, if Figure 7 As shown, the third conducting channel 130, the fourth conducting channel 140 and the fifth conducting channel 150 can together constitute one group of multiple channel groups, wherein two third conducting channels 130 can be provided, and the two third conducting channels 130 are arranged at intervals in the axial direction of the valve core 100, the fourth conducting channel 140 can be opposite to the inlet or outlet of the third conducting channel 130 in the axial direction, the fifth conducting channel 150 and the fourth conducting channel 140 are spaced apart in the circumferential direction of the valve core 100, and when the fourth conducting channel 140 is opposite to the inlet of the third conducting channel 130 in the axial direction, the fifth conducting channel 150 is opposite to the outlet of the third conducting channel 130.

[0112] When the valve core 100 is driven to rotate until the group of flow channels is opposite to the multi-column valve port column 211, each third conducting flow channel 130 can connect two valve ports 2111 adjacently arranged in the circumferential direction, while the fourth conducting flow channel 140 can connect two valve ports 2111 adjacently arranged in the axial direction, and the fifth conducting flow channel 150 can connect two valve ports 2111 spaced apart in the axial direction to form a connected state of the multi-way valve 200.

[0113] It should be noted that the flow channel group can meet at least one of the above five conditions, for example: the flow channel group simultaneously meets A1 and A2, or A1 and A3, or A1, A2, A3, or A1 to A4, or A1 to A5, etc., which are not listed here one by one. The specific layout of the flow channel group can be determined according to actual production requirements and is not specifically limited here.

[0114] Combine Figures 3 to 8In some embodiments of the present invention, the multiple flow channel groups include a first flow channel group 101 to a fifth flow channel group 105, and the first flow channel group 101 and the fifth flow channel group 105 respectively meet conditions A1 to A5. On the cross section of the valve core 100, with the positive projection of the rotation axis of the valve core 100 as the center of the circle, the corresponding central angles of the first flow channel group 101 to the fifth flow channel group 105 are equal, so as to simplify the processing of the valve core 100 and at the same time help to simplify the rotation logic of the valve core 100; and / or, the two adjacent flow channel groups are respectively arranged flush at both ends of the valve core 100 in the radial direction.

[0115] Specifically, a plurality of third conducting channels 130 spaced apart along the axial direction of the valve core 100 constitute a first channel group 101. For example, four third conducting channels 130 are provided, and the four third conducting channels 130 can be spaced apart along the axial direction of the valve core 100 to constitute a first channel group 101.

[0116] A plurality of fourth conducting flow channels 140 arranged at intervals along the circumferential direction and / or axial direction of the valve core 100 constitute a second flow channel group 102. For example, when there are two valve port rows 211, four fourth conducting flow channel 140 groups can be provided, and on the projection surface in the radial direction of the valve core 100, the four fourth conducting flow channel 140 groups are arranged in a rectangular shape to form the second flow channel group 102.

[0117] At least one third conducting channel 130 and at least one fourth conducting channel 140 arranged at intervals along the axial direction of the valve core 100 constitute a third channel group 103. For example, three third conducting channels 130 arranged in sequence along the axial direction and one fourth conducting channel 140 can be provided on the valve core 100. The inlet or outlet of the fourth conducting channel 140 and the third conducting channel 130 are arranged opposite to each other in the axial direction to form the third channel group 103.

[0118] A plurality of conducting structures 110 spaced apart along the circumferential direction of the valve core 100 constitute a fourth flow channel group 104 . For example, two conducting structures 110 may be provided on the valve core 100 , and the two conducting structures 110 are spaced apart along the circumferential direction of the valve core 100 to constitute the fourth flow channel group 104 .

[0119] At least one of the third conducting channel 130 and the fourth conducting channel 140 and the fifth conducting channel 150 form the fifth channel group 105. For example, two third conducting channels 130 can be provided, and the two third conducting channels 130 are arranged at intervals in the axial direction of the valve core 100. The fourth conducting channel 140 can be opposite to the inlet or outlet of the third conducting channel 130 in the axial direction. The fifth conducting channel 150 and the fourth conducting channel 140 are spaced apart in the circumferential direction of the valve core 100, and when the fourth conducting channel 140 is opposite to the inlet of the third conducting channel 130 in the axial direction, the fifth conducting channel 150 is opposite to the outlet of the third conducting channel 130 to form the fifth channel group 105.

[0120] Furthermore, each group of flow channel groups is arranged at intervals in the circumferential direction of the valve core 100, and on the projection surface in the axial direction of the valve core 100, the positive projection of each group of flow channel groups is arc-shaped, and the arc lengths corresponding to each group of flow channel groups are the same, so as to facilitate the processing of the valve core 100 and make the structure of the valve core 100 regular.

[0121] Or, in the radial direction of the valve core 100, the ends of the two adjacent flow channel groups away from the central axis L of the valve core 100 are located on the same arc surface, and the ends of the two adjacent flow channel groups close to the central axis L of the valve core 100 in the radial direction are located on the same arc surface, and the spacing between the two arc surfaces is the same. It can also be understood that the depths of the two adjacent flow channel groups in the radial direction are the same, which facilitates the processing of the valve core 100 and is conducive to making the structure of the valve core 100 regular.

[0122] Optionally, the central angles corresponding to the first flow channel group 101 to the fifth flow channel group 105 are equal, and at the same time, the two adjacent flow channel groups are respectively arranged flush at both ends of the valve core 100 in the radial direction, so as to further improve the processing convenience of the valve core 100 and ensure the regularity of the valve core 100 structure.

[0123] In some embodiments of the present invention, the multi-way valve 200 has multiple connectivity states, including a first connectivity state and a second connectivity state. In the first connectivity state, one group of flow channel groups corresponds to all valve port columns 211, and all valve ports 2111 are connected to the flow channel group; in the second connectivity state, one group of flow channel groups corresponds to all valve port columns 211, and at least one valve port 2111 is closed by the valve core 100.

[0124] Specifically, in the first connected state, one of the multiple flow channel groups is arranged corresponding to the multiple valve port columns 211, and the valve ports 2111 of the multiple valve port columns 211 are all in a state of being connected to the group of flow channel groups, that is, all valve ports 2111 are in an open state, so that all external pipelines connected to the valve ports 2111 are in a passage state, which is convenient for injecting fluid into the thermal management system 300.

[0125] It should be noted that “corresponding setting” can be understood as the flow channel group corresponding to the valve port column 211 is used to connect the corresponding valve port 2111 on the shell 210, while the flow channel group not corresponding to the valve port column 211 is not used to connect the corresponding valve port 2111 on the shell 210.

[0126] Furthermore, in the second connectivity state, one of the multiple flow channel groups is arranged corresponding to all the valve ports 2111, and at least one of all the valve ports 2111 corresponds to a position on the valve core 100 where no flow channel is formed, that is, at least one of all the valve ports 2111 is closed by the outer peripheral wall of the valve core 100, so that at least one of the multiple valve ports 2111 is in a closed state. In the second connectivity state, the multi-way valve 200 can connect different external pipelines to facilitate switching the connectivity mode of the thermal management system 300.

[0127] Optionally, the number of closed valve ports 2111 can be 1, 2 or 3, etc. The specific number limit can be determined according to the arrangement of the flow channel group on the valve core 100 and the number arrangement of the valve ports 2111, and is not specifically limited here.

[0128] It should be noted that the "second connection state" refers to the state in which different external pipelines are connected when the multi-way valve 200 is applied to the mode switching of the thermal management system 300. The second connection state may include multiple modes in which the multi-way valve 200 connects different external pipelines.

[0129] In some embodiments of the present invention, at least one flow channel group is configured to enable the multi-way valve 200 to switch between a first communication state and a second communication state.

[0130] For example, one of the multiple flow channel groups is configured to enable the multi-way valve 200 to switch between a first connection state and a second connection state, and the angle between the flow channel group and the valve port array 211 in the circumferential direction is adjusted by driving the valve core 100 to rotate.

[0131] Exemplarily, the flow channel group has multiple flow channel inlets and multiple flow channel outlets. In the second communication state, each flow channel inlet is opposite to the corresponding valve port 2111 in the radial direction, each flow channel outlet is opposite to the corresponding valve port 2111, and at least one valve port 2111 in the multiple valve port rows 211 is closed by the valve core 100; in the first communication state, relative to the second communication state, each flow channel inlet and the corresponding valve port 2111 (in the first communication state and the second communication state, the valve port 2111 corresponding to the same flow channel inlet is the same) are staggered in the circumferential direction, but each flow channel inlet and the corresponding valve port 2111 are still in a communication state, each flow channel outlet and the corresponding valve port 2111 (in the first communication state and the second communication state, the valve port 2111 corresponding to the same flow channel outlet is the same) are staggered in the circumferential direction, but each flow channel outlet and the corresponding valve port 2111 are still in a communication state, so that all valve ports 2111 are connected to the flow channels in the flow channel group.

[0132] It should be noted that, "multiple flow channel inlets" include the inlets of multiple conducting flow channels, and "multiple flow channel outlets" include the outlets of multiple conducting flow channels. The inlet of each of the first conducting flow channel 111 to the fifth conducting flow channel 150 mentioned above is a flow channel inlet, and each outlet of the first conducting flow channel 111 to the fifth conducting flow channel 150 is a flow channel outlet. For example, when the flow channel group is the first flow channel group 101, the multiple flow channel inlets include the inlets of multiple third conducting flow channels 130 arranged at intervals along the axial direction, and the multiple flow channel outlets include the outlets of multiple third conducting flow channels 130 arranged at intervals along the axial direction. Examples are not given one by one here.

[0133] Therefore, by setting at least one group of flow channel groups, the multi-way valve 200 can be switched between the first connection state and the second connection state, which is beneficial to reducing the number of flow channel groups, reducing the structural complexity of the valve core 100, and reducing the processing difficulty of the valve core 100, thereby improving the production and processing efficiency of the valve core 100.

[0134] It is understood that multiple flow channel groups can be provided to enable the multi-way valve 200 to switch between the first and second communication states. When the multi-way valve 200 needs to switch between the first and second communication states, the valve core 100 can be rotated to adjust the relative circumferential position between the valve port array 211 and the adjacent flow channel groups, thereby facilitating the switching of the multi-way valve 200 between the first and second communication states and reducing the difficulty of controlling the multi-way valve 200.

[0135] like Figure 2As shown, in some embodiments of the present invention, the number of valve ports 2111 in each valve port column 211 is greater than or equal to 4, so as to increase the number of valve ports 2111 within the limited space of the multi-way valve 200, thereby increasing the number of external pipelines that the multi-way valve 200 can be connected to, and through the cooperation of the valve ports 2111 and the flow channel group, it is beneficial to realize multiple connection states of the multi-way valve 200 and improve the functionality of the multi-way valve 200.

[0136] Combine Figures 3 to 7 In some embodiments of the present invention, at least two of a third conducting channel 130, a fourth conducting channel 140, and a fifth conducting channel 150 are further formed on the valve core 100. The at least two of the third conducting channel 130, the fourth conducting channel 140, and the fifth conducting channel 150 are spaced apart in the circumferential direction or the axial direction, and the at least two of the third conducting channel 130, the fourth conducting channel 140, and the fifth conducting channel 150 are spaced apart in the axial direction or the circumferential direction respectively with respect to the conducting structure 110. Each channel group includes at least one of the conducting structure 110, the third conducting channel 130, the fourth conducting channel 140, and the fifth conducting channel 150.

[0137] For example, the third conducting channel 130 extends along the circumferential direction of the valve core 100, and the third conducting channel 130 forms an inlet and an outlet of the third conducting channel 130 arranged adjacently on both sides of the circumferential direction, and the third conducting channel 130 can connect two opposite valve ports 2111 in two adjacent valve port columns 211; the fourth conducting channel 140 extends along the axial direction of the valve core 100, and the fourth conducting channel 140 forms an inlet and an outlet of the fourth conducting channel 140 arranged adjacently on both sides of the axial direction of the valve core 100, and the fourth conducting channel 140 can connect two adjacent valve ports 2111 in the same valve port column 211; the fifth conducting channel 150 extends along the axial direction of the valve core 100, and the inlet and the outlet of the fifth conducting channel 150 arranged spaced apart at both ends of the fifth conducting channel 150 in the axial direction, and the fifth conducting channel 150 can connect two valve ports 2111 arranged spaced apart in the same valve port column 211.

[0138] It is understandable that the specific arrangement of the flow channel on the valve core 100 can be determined according to actual use requirements and is not specifically limited here.

[0139] Further, combined with Figure 5 and Figure 8 The fifth conducting channel 150 has the same structure as the first conducting channel 111 , and the fourth conducting channel 140 has the same structure as the second conducting channel 112 .

[0140] For example, the inlet and outlet of the fifth conducting channel 150 are both formed on the outer peripheral wall of the valve core 100 and extend in the radial direction toward the center axis L of the valve core 100. The fifth conducting channel 150 includes a connecting section, which extends in the axial direction of the valve core 100, and the two ends of the connecting section in the axial direction are respectively connected to the inlet and outlet of the fifth conducting channel 150, that is, the structure of the fifth conducting channel 150 is the same as that of the first conducting channel 111, which facilitates the processing of the valve core 100 and is conducive to ensuring the regularity of the structure of the valve core 100.

[0141] The fourth conducting channel 140 and the second conducting channel 112 are both formed on the outer peripheral wall of the valve core 100 and extend in the axial direction, so as to further improve the processing convenience of the valve core 100, ensure the regular structure of the valve core 100, and reduce the structural complexity of the valve core 100.

[0142] It should be noted that "same structure" means the same shape, but the size can be the same or different. The specific size design between the first conducting channel 111 and the fifth conducting channel 150 and the size between the fourth conducting channel 140 and the second conducting channel 112 can be determined according to actual production requirements and are not specifically limited here.

[0143] like Figure 2 As shown, in some embodiments of the present invention, the multi-column valve port column 211 includes an adjacent first valve port column a and a second valve port column b, and the number of valve ports 2111 of the first valve port column a is greater than the number of valve ports 2111 of the second valve port column b, so as to increase the number of valve ports 2111 and the number of pipelines connected to the multi-way valve 200. At the same time, the valve port column 211 cooperates with the flow channel groups of different structures, which is conducive to increasing the connectivity states that can be achieved by the multi-way valve 200.

[0144] Combine Figures 2 to 7 In some embodiments of the present invention, the number of first valve port rows a is 5, the number of second valve port rows b is 4, and the multiple flow channel groups include a first flow channel group 101 to a fifth flow channel group 105. Four third conducting flow channels 130 spaced apart in the axial direction constitute the first flow channel group 101; four fourth conducting flow channels 140 spaced apart in the axial and circumferential directions constitute the second flow channel group 102; three third conducting flow channels 130 and one fourth conducting flow channel 140 spaced apart in the axial direction constitute the third flow channel group 103; two conducting structures 110 spaced apart in the circumferential direction constitute the fourth flow channel group 104; two third conducting flow channels 130 and one fourth conducting flow channel 140 spaced apart in the axial direction, and a fifth conducting flow channel 150 constitute the fifth flow channel group 105.

[0145] Specifically, the first valve port column a includes a first valve port 1, a second valve port 2, a third valve port 3, a fourth valve port 4 and a fifth valve port 5 arranged along the axial direction, and the second valve port column b includes a sixth valve port 6, a seventh valve port 7, an eighth valve port 8 and a ninth valve port 9 arranged along the axial direction.

[0146] When the valve core 100 is driven to rotate until the first flow channel group 101 is opposite to the two valve port columns 211 in the radial direction, the first valve port 1, the second valve port 2, the third valve port 3 and the fourth valve port 4 in the first valve port column a are respectively arranged in one-to-one correspondence with and connected to the inlets of the four third conducting flow channels 130 in the first flow channel group 101, the fifth valve port 5 is arranged opposite to the outer peripheral wall of the valve core 100 and is closed by the valve core 100, and the sixth valve port 6, the seventh valve port 7, the eighth valve port 8 and the ninth valve port 9 in the second valve port column b are respectively arranged in one-to-one correspondence with and connected to the outlets of the four third conducting flow channels 130, the first valve port 1 is connected to the sixth valve port 6, the second valve port 2 is connected to the seventh valve port 7, the third valve port 3 is connected to the eighth valve port 8, and the fourth valve port 4 is connected to the ninth valve port 9, so as to realize the first connection mode of the multi-way valve 200 in the second connection state.

[0147] When the second flow channel group 102 is opposite to the two valve port columns 211 in the radial direction, the first valve port 1, the second valve port 2, the third valve port 3 and the fourth valve port 4 in the first valve port column a are respectively arranged opposite to the two fourth conducting flow channels 140 arranged at intervals along the axial direction in the second flow channel group 102, and the first valve port 1 and the second valve port 2 are connected, the third valve port 3 and the fourth valve port 4 are connected, and the fifth valve port 5 is closed by the valve core 100. The sixth valve port 6, the seventh valve port 7, the eighth valve port 8 and the ninth valve port 9 in the second valve port column b are respectively arranged opposite to and connected to the other two fourth conducting flow channels 140 arranged at intervals along the axial direction in the second flow channel group 102, and the sixth valve port 6 is connected to the seventh valve port 7, and the eighth valve port 8 is connected to the ninth valve port 9, so as to realize the second connection mode of the multi-way valve 200 in the second connection state.

[0148] Three third conducting channels 130 spaced apart in the axial direction and a fourth conducting channel 140 opposite to the inlet or outlet of the third conducting channel 130 together constitute a third channel group 103. When the third channel group 103 is opposite to the two rows of valve ports 211 in the radial direction, the first valve port 1 is connected to the sixth valve port 6, the second valve port 2 is connected to the seventh valve port 7, the third valve port 3 is connected to the eighth valve port 8, the fourth valve port 4 is connected to the fifth valve port 5, and the ninth valve port 9 is closed by the valve core 100, so as to realize the third connection mode of the multi-way valve 200 in the second connection state.

[0149] In addition, the third flow channel group 103 can also realize the first connected state of the multi-way valve 200. The inlets of the three third conducting flow channels 130 and the inlet of the fourth conducting flow channel 140 are staggered with the corresponding valve ports 2111 on the first valve port array a. However, the inlets of the three third conducting flow channels 130 and the inlet of the fourth conducting flow channel 140 are still in a connected state with the corresponding valve ports 2111 on the first valve port array a. The outlets of the three conducting flow channels 130 and the outlet of the fourth conducting flow channel 140 are connected to the corresponding valve ports 2111 on the first valve port array. Although the valves 2111 of the multi-way valve 200 are staggered, the inlets of the three third conducting channels 130 and the inlet of the fourth conducting channel 140 are still connected to the corresponding valve ports 2111 on the first valve port row a. The first valve port 1 and the sixth valve port 6, the second valve port 2 and the seventh valve port 7, and the third valve port 3 and the eighth valve port 8 are all connected through the third conducting channel 130. At the same time, the fourth valve port 4, the fifth valve port 5 and the ninth valve port 9 are connected through the fourth conducting channel 140, so that all the valve ports 2111 of the multi-way valve 200 are opened, realizing the first connected state of the multi-way valve 200.

[0150] When the fourth flow channel group 104 is opposite to the two valve port rows 211 in the radial direction, the first valve port 1 is connected to the fourth valve port 4, the second valve port 2 is connected to the third valve port 3, the sixth valve port 6 is connected to the ninth valve port 9, the seventh valve port 7 is connected to the eighth valve port 8, and the fifth valve port 5 is closed by the valve core 100 to realize the fourth connection mode of the multi-way valve 200 in the second connection state.

[0151] The fourth conducting channel 140 and the fifth conducting channel 150 of the fifth channel group 105 are spaced apart in the axial direction, and the fourth conducting channel 140 and the fifth conducting channel 150 are respectively arranged opposite to the inlet and outlet of the third conducting channel 130. When the fifth channel group 105 is opposite in the radial direction, the first valve port 1 and the sixth valve port 6 are connected, the second valve port 2 and the seventh valve port 7 are connected, the third valve port 3 and the fifth valve port 5 are connected, the eighth valve port 8 and the ninth valve port 9 are connected, and the fourth valve port 4 is closed by the valve core 100 to realize the fifth communication mode of the multi-way valve 200 in the second communication state.

[0152] Reference Figure 1 In some embodiments of the present invention, the multi-way valve 200 further includes a first sealing member 220 , which is disposed between the housing 210 and the valve core 100 and is provided with a plurality of annular sealing portions 221 , each annular sealing portion 221 surrounding a corresponding valve port 2111 of the valve port array 211 .

[0153] Specifically, a mounting groove 214 is formed on the inner circumferential wall of the shell 210 and is arranged opposite to the valve port row 211 in the radial direction. The mounting groove 214 is recessed in the radial direction away from the center axis L of the shell 210. The first seal 220 can be positioned and installed through the mounting groove 214, and the first seal 220 can be embedded in the mounting groove 214 so that the first seal 220 can be arranged between the valve core 100 and the shell 210. At the same time, it can prevent the first seal 220 from rotating when the valve core 100 rotates, thereby ensuring the assembly stability of the first seal 220.

[0154] Furthermore, the size of the first seal 220 in the circumferential direction is adapted to the size of the two rows of valve ports 211 in the circumferential direction to ensure the sealing effect of the first seal 220 on the valve ports 2111, and at the same time prevent the increase in production costs due to the excessive size of the first seal 220, and a plurality of annular sealing portions 221 are formed on the first seal 220, and the plurality of annular sealing portions 221 are arranged in a one-to-one correspondence with the plurality of valve ports 2111, and each annular sealing portion 221 extends along the circumferential direction of the valve port 2111 opposite thereto, so as to play a sealing role between the valve core 100 and the valve port 2111, thereby improving the sealing performance of the multi-way valve 200 and reducing the risk of fluid leakage and crossflow.

[0155] In some embodiments of the present invention, a PTFE (polytetrafluoroethylene) coating is provided on the side of the first seal 220 close to the valve core 100 in the radial direction, so that the side of the first seal 220 close to the valve core 100 in the radial direction has the characteristics of wear resistance and a low friction coefficient, which is beneficial to improving the friction and wear performance of the first seal 220, ensuring the sealing effect of the first seal 220 between the valve core 100 and the valve port 2111, while reducing the friction force generated between the valve core 100 and the valve core 100 during rotation, thereby reducing the load on the multi-way valve 200 when switching the connection state.

[0156] Furthermore, a side of the first sealing member 220 close to the housing 210 in the radial direction is made of EPDM (ethylene propylene diene monomer) material to ensure sealing between the first sealing member 220 and the valve port 2111 .

[0157] In some embodiments of the present invention, the valve port row 211 is provided with mounting structures 230 on both sides of the circumference of the multi-way valve 200, and the outer peripheral wall of the shell 210 is provided with a plurality of first reinforcing ribs 212 extending in the circumferential direction and a plurality of second reinforcing ribs 213 extending in the axial direction. Each first reinforcing rib 212 and each second reinforcing rib 213 are cross-arranged, and the two ends of the length of each first reinforcing rib 212 are respectively connected to two mounting structures 230.

[0158] Specifically, a plurality of first reinforcing ribs 212 extending along the circumferential direction of the shell 210 are spaced apart in the axial direction of the shell 210, and a plurality of second reinforcing ribs 213 extending along the axial direction of the shell 210 are spaced apart in the circumferential direction of the shell 210, and each second reinforcing rib 213 is cross-arranged and connected with a plurality of first reinforcing ribs 212 to improve the structural strength of the shell 210 and ensure the protective effect of the shell 210 on the valve core 100.

[0159] Furthermore, a mounting structure 230 is provided on the shell 210, and the shell 210 can be positioned and installed through the mounting structure 230, wherein the mounting structure 230 is arranged on both sides of the valve port column 211 in the circumferential direction of the multi-way valve 200, and the first reinforcing rib 212 is respectively connected to the mounting structure 230 located on both sides of the valve port column 211 at its two ends extending in the circumferential direction (i.e. in the length direction) to support between the mounting structure 230 and the shell 210, thereby improving the strength of the mounting structure 230 and preventing the mounting structure 230 from being crushed.

[0160] like Figure 1 As shown, in some embodiments of the present invention, a mounting seat 240 is provided at one end of the housing 210 in the axial direction, and the mounting seat 240 is used to install the actuator 400. The actuator 400 is transmission-connected to the valve core 100 and is used to drive the valve core 100 to rotate in the mounting cavity 215 to switch the connectivity state of the multi-way valve 200.

[0161] Furthermore, the shell 210 also includes an end cover 260, which is covered at the open end of the shell 210 and connected to the shell 210. The end cover 260 is used to close the open end of the shell 210 so that a closed installation cavity 215 can be formed in the shell 210 to prevent the valve core 100 from falling out of the shell 210.

[0162] The end cover 260 and the housing 210 may be connected by welding, or the end cover 260 and the housing 210 may be sealed by a threaded connection (eg, a screw) and a sealing ring.

[0163] The thermal management system 300 according to the present invention includes the multi-way valve 200 described above.

[0164] Exemplarily, the thermal management system 300 includes a compressor, at least one first heat exchanger, at least one second heat exchanger and a plurality of external pipelines, wherein the plurality of external pipelines are filled with a circulating heat exchange medium and the plurality of external pipelines are used to connect the above-mentioned compressor, the first heat exchanger and the second heat exchanger, and at the same time, the plurality of external pipelines are respectively connected to different valve ports 2111 on the multi-way valve 200. By switching the connection state of the multi-way valve 200, the flow path of the heat exchange medium can be switched, thereby facilitating the switching of the heat exchange mode of the thermal management system 300; wherein, the first heat exchanger can be used for heat exchange with the battery, and the second heat exchanger can be used for heat exchange with the vehicle cabin.

[0165] It can be understood that in each connection state of the multi-way valve 200, at least two valve ports 2111 are connected. For example, in one of the connection states of the multi-way valve 200, all valve ports 2111 participate in the circulation of the heat exchange medium, and each valve port 2111 is connected to the corresponding conducting channel on the valve core 100. For example, in one of the connection states of the multi-way valve 200, each of at least two valve ports 2111 is connected to the corresponding conducting channel on the valve core 100, and the remaining valve ports 2111 are closed by the valve core 100 and do not participate in the circulation of the heat exchange medium.

[0166] Since the thermal management system 300 is provided with the above-mentioned multi-way valve 200, a plurality of flow channel groups with different structures are provided on the valve core 100 to improve the space utilization rate of the valve core 100, and a plurality of valve port columns 211 are provided on the shell 210, and the valve port columns 211 are switched and connected with the plurality of flow channel groups to realize a plurality of connection modes of the multi-way valve 200. For the same valve port column 211, by providing a conducting structure 110, the second conducting flow channel 112 can connect two adjacent valve ports 2111, and the first conducting flow channel 111 can connect two valve ports 2111 separated by the above-mentioned two valve ports 2111, so that different valve ports 2111 of the same valve port column 211 are connected, thereby increasing the applicable scenarios of the multi-way valve 200, improving the performance of the multi-way valve 200, and helping to reduce the arrangement of the valve body in the thermal management system 300, thereby helping to realize the miniaturization design of the thermal management system 300 and reducing the production cost of the thermal management system 300.

[0167] Reference Figure 1 In some embodiments of the present invention, the multi-way valve 200 further includes a second seal 250, which is located on the side of the valve port array 211 away from the central axis L of the multi-way valve 200 in the radial direction. The second seal 250 is used to seal the valve port 2111 and the external pipeline, thereby preventing leakage of the fluid (which can also be understood as a heat exchange medium) during the process of flowing from the external pipeline into the multi-way valve 200, thereby improving the connection sealing between the external pipeline and the multi-way valve 200.

[0168] like Figure 10 As shown, a vehicle 1000 according to an embodiment of the present invention includes the multi-way valve 200 or the thermal management system 300 .

[0169] Since the vehicle 1000 is provided with the above-mentioned multi-way valve 200 or the above-mentioned thermal management system 300, a plurality of flow channel groups with different structures are provided on the valve core 100 to improve the space utilization rate of the valve core 100, and a plurality of valve port columns 211 are provided on the shell 210, and the valve port columns 211 are switched and connected with the plurality of flow channel groups to realize a plurality of connection modes of the multi-way valve 200, thereby improving the performance of the multi-way valve 200, and helping to reduce the arrangement of the valve body in the thermal management system 300, thereby helping to realize the miniaturized design of the thermal management system 300, and can reduce the production cost of the thermal management system 300.
