[0053] 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.

[0054] Reference below Figures 1-8 A valve core 100 according to an embodiment of the present invention is described.

[0055] Combine Figure 2 、 Figure 7 and Figure 8According to the valve core 100 of the embodiment of the present invention, at least one conducting structure 110 is provided on the valve core 100, and the conducting structure 110 includes a first conducting channel 111 and a second conducting channel 112 arranged at intervals. The first conducting channel 111 has 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. In the radial direction of the valve core 100, the first channel section 13 is located radially inside the second channel section 23, and the first channel section 13 is radially opposite to the second channel section 23.

[0056] It can be seen that the fluid can flow into the first flow channel section 13 through the first inlet 11 and flow out of the first conductive flow channel 111 through the first outlet 12; the fluid can flow into the second flow channel section 23 through the second inlet 21 and flow out of the second conductive flow channel 112 through the second outlet 22.

[0057] Since the first conducting channel 111 and the second conducting channel 112 are arranged at intervals, the medium in the first conducting channel 111 will not flow directly into the second conducting channel 112, and similarly, the medium in the second conducting channel 112 will not flow directly into the first conducting channel 111, so that the valve core 100 can define different fluid flow paths.

[0058] In addition, since the first flow channel section 13 and the second flow channel section 23 are both formed on the valve core 100, and the first flow channel section 13 is located radially inside the second flow channel section 23 and the first flow channel section 13 and the second flow channel section 23 are arranged opposite to each other in the radial direction, then in the radial direction of the valve core 100, the distance between the first flow channel section 13 and the central axis of the valve core 100 is smaller than the distance between the second flow channel section 23 and the central axis of the valve core 100. The first flow channel section 13 and the second flow channel section 23 can form an inner and outer double-layer flow channel on the valve core 100 along the radial direction of the valve core 100, while increasing the flow path of the fluid, reasonably allocating the space inside the valve core 100, improving the space utilization rate of the valve core 100, and being conducive to realizing the miniaturization design of the valve core 100, and being conducive to reducing the complexity of the structural design of the valve core 100.

[0059] Optionally, multiple conducting structures 110 may be provided to further increase the flow path of the fluid on the valve core 100, increase the connectivity of the multi-way valve 200, and further improve the integration of the valve core 100 and the volume of the valve core 100. Of course, it is understood that only one conducting structure 110 may be provided, and the specific number of conducting structures 110 may be determined according to actual production requirements and is not specifically limited here.

[0060] In the related art, in order to improve the functionality of the multi-way valve, multiple flow channel structures are usually set on the valve core. However, due to the lack of reasonable planning of the space on the valve core, the volume of the valve core needs to be increased to ensure that there is enough space on the valve core to arrange multiple flow channel structures, resulting in an increase in the volume of the multi-way valve, which causes the multi-way valve to occupy a larger installation space and is inconvenient to arrange.

[0061] The present application sets a first conducting flow channel 111 and a second conducting flow channel 112 that are set at intervals, so that the valve core 100 can define different flow paths of the fluid, and by setting the first flow channel section 13 on the radial inner side of the second flow channel section 23, the first flow channel section 13 and the second flow channel section 23 form an inner and outer double-layer flow channel on the valve core 100 along the radial direction of the valve core 100, thereby realizing a reasonable distribution of the space within the valve core 100, improving the space utilization of the valve core 100, and being conducive to realizing a miniaturized design of the valve core 100, thereby realizing a miniaturized design of the multi-way valve 200, saving the space required for arranging the multi-way valve 200, and being conducive to reducing the complexity of the structural design of the valve core 100.

[0062] 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.

[0063] Combine Figure 2 and Figure 7 In some embodiments of the present invention, in the axial direction of the valve core 100 , the first inlet 11 and the first outlet 12 are spaced apart, and the second inlet 21 and the second outlet 22 are both spaced apart between the first inlet 11 and the first outlet 12 .

[0064] Illustratively, in the axial direction of the valve core 100, the first inlet 11 and the first outlet 12 are spaced apart, which is beneficial to prevent fluid backflow caused by the first inlet 11 and the first outlet 12 being close to each other, and to ensure the flow direction of the fluid. The second inlet 21 and the second outlet 22 are both located between the first inlet 11 and the second inlet 21, and the second flow channel section 23 is located radially outside the first flow channel section 13, so as to simplify the structural design of the first conducting flow channel 111 and the second conducting flow channel 112, which is beneficial to avoid mutual interference between the first conducting flow channel 111 and the second conducting flow channel 112, and to ensure the independence between the first conducting flow channel 111 and the second conducting flow channel 112. Among them, the second inlet 21 and the second outlet 22 can be arranged at intervals along the axial direction of the valve core 100, or the second inlet 21 and the second outlet 22 can be arranged in communication along the axial direction of the valve core 100. In this case, the valve core 100 is used in the multi-way valve 200, and the second inlet 21 and the second outlet 22 can be separated by other components of the multi-way valve 200 (such as the housing 210 or the first sealing member 220 described later).

[0065] In some embodiments of the present invention, the valve core 100 is configured to satisfy at least one of the following conditions:

[0066] Under condition A1 , the first inlet 11 , the first outlet 12 , the second inlet 21 , and the second outlet 22 are located on the same straight line parallel to the axial direction of the valve core 100 .

[0067] For example: the first inlet 11 and the first outlet 12 can be located on the same straight line parallel to the central axis of the valve core 100, which is beneficial to shortening the length of the first conducting channel 111, thereby shortening the flow path of the fluid, and at the same time helping to save the circumferential space occupied by the first conducting channel 111, making it easier to arrange other channel structures on the valve core 100.

[0068] The second inlet 21 and the second outlet 22 can be located on the same straight line parallel to the central axis of the valve core 100, which is beneficial to shortening the length of the second conducting channel 112, thereby shortening the flow path of the fluid, and at the same time helping to save the circumferential space occupied by the second conducting channel 112, making it easier to arrange other channel structures on the valve core 100.

[0069] Reference Figure 7 , or the first inlet 11, the first outlet 12, the second inlet 21 and the second outlet 22 are located on the same straight line parallel to the central axis of the valve core 100, so as to shorten the length of the first conducting channel 111 and the second conducting channel 112 respectively, thereby shortening the flow path of the fluid, and at the same time helping to further save the circumferential space occupied by the conducting structure 110, and facilitating the arrangement of other flow channel structures on the valve core 100.

[0070] Of course, it is understandable that the first inlet 11, the first outlet 12, the second inlet 21 and the second outlet 22 may also have other arrangements, for example: two or three of the first inlet 11, the first outlet 12, the second inlet 21 and the second outlet 22 are located on the same straight line parallel to the central axis of the valve core 100, which is not specifically limited here; for another example, the first inlet 11, the second inlet 21, the first outlet 12 and the second outlet 22 are arranged in an axial spiral along the valve core 100.

[0071] Condition A2: The second conducting channel 112 penetrates the outer peripheral wall of the valve core 100 to form a first opening. A portion of the first opening forms the second inlet 21 , and the other portion forms the second outlet 22 . At this time, the second inlet 21 and the second outlet 22 are connected.

[0072] For example, Figure 7 As shown, the second conducting channel 112 is constructed as a linear channel. For example, the second conducting channel 112 can extend along the axial direction of the valve core 100, wherein the top end of the second conducting channel 112 can be formed as a second inlet 21, and the bottom end of the second conducting channel 112 can be formed as a second outlet 22, and a second channel section 23 is formed between the second inlet 21 and the second outlet 22, so as to further shorten the length of the second conducting channel 112, save the space required for arranging the second conducting channel 112, and facilitate the processing of the second conducting channel 112.

[0073] like Figure 7 As shown, under condition A3, both the first flow channel segment 13 and the second flow channel segment 23 extend along the axial direction of the valve core 100, and the length of the first flow channel segment 13 is greater than the length of the second flow channel segment 23. It is understood that either the first flow channel segment 13 or the second flow channel segment 23 can extend in a straight line parallel to the axial direction of the valve core 100, or extend in a curved line parallel to the axial direction of the valve core 100, or extend in a spiral direction at a non-zero angle to the axial direction of the valve core 100, etc.

[0074] Specifically, since the first flow channel section 13 is arranged on the radial inner side of the second flow channel section 23, by making the length of the first flow channel section 13 greater than the length of the second flow channel section 23, the two ends of the length of the first flow channel section 13 can be respectively protruded from the two ends of the length of the second flow channel section 23, so that the first inlet 11 and the first outlet 12 are connected to the first flow channel section 13, and the second inlet 21 and the second outlet 22 are connected to the second flow channel section 23, which is beneficial to saving the space occupied by the first conducting flow channel 111 and the second conducting flow channel 112 in the circumferential direction of the valve core 100. At the same time, the first conducting flow channel 111 and the second conducting flow channel 112 are not easy to interfere with each other, which facilitates the processing of the first conducting flow channel 111 and the second conducting flow channel 112.

[0075] It should be noted that “length” refers to the size of the first flow channel section 13 and the second flow channel section 23 in the axial direction of the valve core 100 .

[0076] Optionally, the valve core 100 is configured to simultaneously meet condition A1, condition A2 and condition A3. For example, the first conducting channel 111 extends in a roughly U-shape, and the opening of the first conducting channel 111 is radially toward the side away from the central axis of the valve core 100. The second conducting channel 112 is located between the first inlet 11 and the first outlet 12 and extends in the axial direction. The first conducting channel 111 wraps the second conducting channel 112. Thus, while improving the space utilization of the valve core 100, the lengths of the first conducting channel 111 and the second conducting channel 112 can be effectively reduced, shortening the time required for the fluid to flow through the multi-way valve 200 and improving the flow efficiency of the fluid.

[0077] Or the valve core 100 can be constructed to satisfy condition A1 and condition A2 at the same time, but not condition A3, or the valve core 100 can be constructed to satisfy condition A1 and condition A3 at the same time, but not condition A2, or the valve core 100 can be constructed to satisfy condition A2 and condition A3 at the same time, but not condition A1, so as to improve the space utilization of the valve core 100, shorten the length of the first conductive channel 111 and the second conductive channel 112, and reduce the processing difficulty of the conductive structure 110 and improve the processing efficiency of the conductive structure 110.

[0078] Of course, it is understandable that the specific structure of the conductive structure 110 can be determined according to actual production requirements, and no specific limitation is made here. As long as the arrangement of the conductive structure 110 can improve the space utilization of the valve core 100 and shorten the length of the first conductive structure 110 and the second conductive structure 110, no specific limitation is made here.

[0079] like Figure 2 As shown, in some embodiments of the present invention, there are multiple conducting structures 110 and they are arranged at intervals along the axial and / or circumferential directions of the valve core 100 to further improve the space utilization on the valve core 100, and each conducting structure 110 includes a first conducting channel 111 and a second conducting channel 112. By setting up multiple conducting structures 110, the channels on the valve core 100 through which the valve core 100 can flow can be increased, which is beneficial to increasing the connectivity state of the multi-way valve 200.

[0080] In some embodiments of the present invention, the flow area of ​​the first conducting channel 111 is equal to the flow area of ​​the second conducting channel 112; and / or 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.

[0081] Specifically, by making the flow area of ​​the first conducting channel 111 the same as the flow area of ​​the second conducting channel 112, it is beneficial to reduce the pressure difference between the fluid flowing out of the first conducting channel 111 and the fluid flowing out of the second conducting channel 112, which is beneficial to reducing the flow resistance of the fluid.

[0082] 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 distance between the opposite walls of the first conducting channel 111 and the second conducting channel 112 is greater than or equal to 1.5 mm, which can also increase the thermal resistance between the first conducting channel 111 and the second conducting channel 112, 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.

[0083] Optionally, the flow area of ​​the first conducting channel 111 is equal to the flow area of ​​the second conducting channel 112, and the distance between the opposite walls of the first conducting channel 111 and the second conducting channel 112 is greater than or equal to 1.5 mm, which is beneficial to reducing the flow resistance of the fluid and improving the structural strength of the conducting structure 110. It can also reduce the heat exchange amount of the fluid in the first conducting channel 111 and the second conducting channel 112, and reduce the influence of the valve core 100 on the flow rate and temperature of the fluid.

[0084] Combine Figure 2 and Figure 7 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 channel 111 and a second conducting channel 112. The first channel section 13 and the second channel section 23 are respectively located on both sides of the first partition 121 in the radial direction of the valve core 100.

[0085] 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 toward the direction close to the central axis 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.

[0086] Reference Figure 8 In some embodiments of the present invention, the thickness t of the first separator 121 satisfies the following relationship: t≥1.5 mm.

[0087] 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 .

[0088] 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 different temperatures of the fluid flowing into the first conductive channel 111 and the second conductive channel 112.

[0089] Combine Figure 2 and Figure 7 In some embodiments of the present invention, the first separator 121 includes two first plates 1211 spaced apart in the axial direction of the valve core 100 and a second plate 1212 connected between the two first plates 1211, the first flow channel section 13 is located on the radial inner side of the second plate 1212, the second flow channel section 23 is located on the radial outer side of the second plate 1212, the first inlet 11 and the first outlet 12 are respectively located on the side of the corresponding first plate 1211 away from the other first plate 1211, and the second inlet 21 and the second outlet 22 are both located between the two first plates 1211.

[0090] 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.

[0091] Furthermore, relative to the second flow channel section 23, the first flow channel section 13 is arranged relatively close to the central axis of the valve core 100, and the length of the first flow channel section 13 in the axial direction is greater than 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.

[0092] Reference Figure 8 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.

[0093] 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. The cross section of the second plate body 1212 is an arc-shaped plate with the central axis of the valve core 100 as the axis. 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. 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.

[0094] 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 fluid flowing out of the first conducting channel 111 and the fluid flowing out of the second conducting channel 112, which is beneficial to reducing the flow resistance of the fluid.

[0095] Combine Figures 2 to 6In 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 provided on the valve core 100, and the above 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.

[0096] like Figure 5 As shown, the third conducting channel 130 penetrates the outer peripheral wall of the valve core 100 to form a second opening 131 extending along the circumference of the valve core 100. A portion of the second opening 131 is formed as the inlet of the third conducting channel 130, and the other portion is formed as the outlet of the third conducting channel 130. The fluid can flow along the circumferential direction of the valve core 100 through the third conducting channel 130.

[0097] For example, in combination Figure 5 and Figure 7 The valve core 100 is formed with a second groove 132 that extends radially toward the central axis of the valve core 100. The second groove 132 is spaced circumferentially from the first groove 120. Second partitions 133 are disposed within the second groove 132 and arranged at intervals along the axial direction. The second partitions 133 extend circumferentially along the valve core 100 and are connected to the groove walls of the second groove 132. The second partitions 133 are used to divide the second groove 132 into a plurality of third conducting channels 130 spaced apart along the axial direction of the valve core 100. The third conducting channels 130 are open on a side radially away from the central axis of the valve core 100 to form a second opening 131. Of course, the arrangement of the plurality of third conducting channels 130 is not limited to this; furthermore, there may be only one third conducting channel 130.

[0098] like Figure 4 As shown, the fourth conducting channel 140 penetrates the outer peripheral wall of the valve core 100 to form a third opening 141 extending axially along the valve core 100. A portion of the third 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. The fluid can flow along the axial direction of the valve core 100 through the fourth conducting channel 140.

[0099] Exemplarily, the valve core 100 is formed with a third groove 142 that is radially recessed toward the central axis of the valve core 100. The third groove 142 is spaced circumferentially from the first groove 120. Third partitions 143 are disposed within the third groove 142 and arranged at intervals along the circumferential direction. The third partitions 143 extend axially along the valve core 100 and are connected to the groove walls of the third groove 142. The third partitions 143 are used to divide the third groove 142 into a plurality of fourth conducting channels 140 spaced apart along the circumferential direction of the valve core 100. The fourth conducting channels 140 are open on a side radially away from the central axis of the valve core 100 to form a third opening 141. Of course, the arrangement of the plurality of fourth conducting channels 140 is not limited to this; furthermore, there may be only one fourth conducting channel 140.

[0100] Combine Figure 3 、 Figure 4 、 Figure 6 and Figure 7 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 , and the inlet and the outlet of the fifth conducting channel 150 are arranged at intervals along the axial direction or circumferential direction of the valve core 100 .

[0101] Exemplarily, a fourth groove 151 can be formed on the valve core 100, which is recessed in the radial direction toward the central axis of the valve core 100. The fourth groove 151 is constructed as a fifth conducting channel 150, wherein the fourth groove 151 is open on the side away from the central axis of the valve core 100, and a fourth separator 152 is provided on the valve core 100. The fourth separator 152 is arranged 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 conducting channel 150, and the inlet and outlet of the fifth conducting channel 150 are respectively located on opposite sides of the fourth separator 152.

[0102] 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 are spaced apart in the circumferential direction of the valve core 100. In this structure, the inlet and outlet of the fifth conducting channel 150 can respectively connect to the two valve ports 2111 on the multi-way valve 200 that are spaced apart in the circumferential direction; 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 are spaced apart in the axial direction of the valve core 100. In this structure, the inlet and outlet of the fifth conducting channel 150 can respectively connect to the two valve ports 2111 of the multi-way valve 200 that are spaced apart in the axial direction.

[0103] Optionally, combined Figures 2 to 6The 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, increase the channels for fluid circulation, and increase the connectivity states of the multi-way valve 200. The fluid can selectively flow into at least one of the first conducting channel 111, the second conducting channel 112, the third conducting channel 130, the fourth conducting channel 140 and the fifth conducting channel 150 to achieve different connectivity states of the multi-way valve 200.

[0104] Combine Figures 2 to 6 In some embodiments of the present invention, the valve core 100 is provided with multiple flow channel groups spaced circumferentially apart. These flow channel groups are adapted to switchably communicate with the valve port group 211 of the multi-way valve 200 to switch the communication state of the multi-way valve 200. In different communication states, different flow channel groups are in corresponding communication with the valve port group 211. Each flow 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. It can be seen that each flow channel group, when moved to a position corresponding to the valve port group 211, can switch the multi-way valve 200 to the corresponding communication state. For example, if there are n flow channel groups, the multi-way valve 200 can have n different communication states, where n is ≥ 2 and is a positive integer.

[0105] Exemplarily, the structures between multiple flow channel groups can be different, for example: the first group of multiple flow channel groups can be composed of multiple third conducting flow channels 130 arranged at intervals along the axial direction, the second group of multiple flow channel groups can be composed of multiple conducting structures 110 arranged at intervals along the circumferential direction, and the third group of multiple flow channel groups can be composed of the third conducting flow channel 130, the fourth conducting flow channel 140 and the fifth conducting flow channel 150.

[0106] Further references Figure 1 The valve port group 211 includes a plurality of valve ports 2111 arranged at intervals along the circumference and axial directions of the multi-way valve 200. The valve port group 211 can be selectively arranged opposite and connected to any of the multiple flow channel groups. For example, when the valve port group 211 is opposite the first flow channel group, the inlet and outlet of each third conducting flow channel 130 are respectively connected to two adjacent valve ports 2111 arranged at intervals along the circumference of the multiple valve ports 2111, thereby achieving one communication state of the multi-way valve 200. When the valve port group 211 is opposite the second flow channel group, the valve ports 2111 at the two axial ends of the multiple valve ports 2111 are respectively connected to the first inlet 11 and the first outlet 12, while the valve ports 2111 located in the middle of the multiple valve ports 2111 are respectively connected to the second inlet 21 and the second outlet 22, thereby achieving another communication state of the multi-way valve 200.

[0107] Thus, the communication state of the multi-way valve 200 is switched by connecting the valve port group 211 to different flow path groups.

[0108] In some embodiments of the present invention, the flow channel group satisfies at least one of the following conditions: Condition B1, 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.

[0109] Specifically, combined Figure 3 and Figure 5 A plurality of third conducting channels 130 are arranged at intervals along the axial direction of the valve core 100 to form one of the channel groups, and the inlet and outlet of each third conducting channel 130 are located at its circumferential ends. Each third conducting channel 130 can connect two valve ports 2111 that are adjacent and arranged at intervals along the circumferential direction to form a connected state of the multi-way valve 200.

[0110] Combine Figure 2 、 Figure 4 and Figure 6 , condition B2, a plurality of fourth conducting flow channels 140 spaced apart along the axial direction and / or circumferential direction of the valve core 100 constitute one of the flow channel groups.

[0111] Optionally, when the size of the fourth conducting channel 140 in the axial direction is small, multiple fourth conducting channels 140 can be arranged at intervals along the circumference and axial direction of the valve core 100 at the same time. For example, four fourth conducting channels 140 can be provided, and the four fourth conducting channels 140 are arranged in a rectangular shape on the outer peripheral wall of the valve core 100 and constitute one of the channel groups. Each fourth conducting channel 140 connects two valve ports 2111 that are adjacent and spaced along the axial direction among the multiple valve ports 2111 to form a connected state of the multi-way valve 200.

[0112] 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 .

[0113] like Figure 5 As shown, in condition B3, 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.

[0114] For example, the valve core 100 may be provided with three third conducting channels 130 spaced apart 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 constitute one of the multiple channel groups.

[0115] Each third conducting channel 130 can connect two valve ports 2111 that are adjacent and spaced apart in the circumferential direction, and at the same time, the fourth conducting channel 140 can connect two valve ports 2111 that are adjacent and spaced apart in the axial direction to form a connected state of the multi-way valve 200.

[0116] Of course, it is understandable that the number of the third conducting channels 130 and the fourth conducting channels 140 can be determined according to actual production requirements and is not specifically limited here.

[0117] like Figure 2 As shown, under condition B4, a plurality of conducting structures 110 spaced apart along the circumference of the valve core 100 form one of the flow channel groups.

[0118] For example, two conducting structures 110 can be spaced apart along the circumferential direction of the valve core 100 to constitute one of the multiple flow channel groups, wherein the first conducting flow channel 111 of each conducting structure 110 can connect the valve ports 2111 located at both ends of the axial direction among the multiple valve ports 2111, and the second conducting flow channel 112 of each conducting structure 110 can connect two adjacent valve ports 2111 located in the middle position of the axial direction among the multiple valve ports 2111 to form a connection mode of the multi-way valve 200.

[0119] 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.

[0120] Reference Figure 6 , condition B5, 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.

[0121] For example, 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 inlet of the fourth conducting channel 140 and the third conducting channel 130 are opposite in the axial direction, the fifth conducting channel 150 is opposite to the outlet of the third conducting channel 130.

[0122] Each third conducting channel 130 can connect two valve ports 2111 that are adjacent and spaced apart in the circumferential direction, while the fourth conducting channel 140 can connect two valve ports 2111 that are adjacent and spaced apart in the axial direction, and the fifth conducting channel 150 can connect two valve ports 2111 that are spaced apart in the axial direction, so as to form a connected state of the multi-way valve 200.

[0123] Optionally, the flow channel group can simultaneously meet conditions B1, B2, B3, B4 and B5 to further improve the space utilization of the valve core 100, and increase the flow channel structure on the valve core 100, so that the multi-way valve 200 can achieve a variety of different connectivity states, ensuring that the multi-way valve 200 can meet usage requirements.

[0124] Optionally, the flow channel group can simultaneously meet two of the above five conditions, for example: the flow channel group simultaneously meets B1 and B2, or B1 and B3, or B1 and B4, or B1 and B5, so as to simplify the structure of the valve core 100 and facilitate the processing of the valve core 100; the flow channel group can simultaneously meet three of the above five conditions, which are not listed here one by one, to increase the flow channel structure on the valve core 100, and at the same time help to simplify the structure of the valve core 100; or the flow channel group can simultaneously meet four of the above five conditions, which are not listed here one by one, to further increase the flow channel structure on the valve core 100 and increase the connection mode that the multi-way valve 200 can achieve.

[0125] Of course, it is understandable that the specific arrangement of the flow channel group can be determined by the actual application conditions of the multi-way valve 200 and is not specifically limited here.

[0126] In some embodiments of the present invention, in the radial direction of the valve core 100 , two ends of two adjacent flow channel groups are respectively and flushly arranged.

[0127] For example, two adjacent flow channel groups are located on the same arc surface at one end away from the central axis in the radial direction, and two adjacent flow channel groups are located on the same arc surface at one end close to the central axis in the radial direction, and the spacing between the two arc surfaces is the same. It can also be understood that the two adjacent flow channel groups have the same depth in the radial direction, which facilitates the processing of the valve core 100 and is conducive to making the structure of the valve core 100 regular.

[0128] Reference Figure 1 According to an embodiment of the present invention, the multi-way valve 200 includes the valve core 100 described above.

[0129] Since the multi-way valve 200 is provided with the above-mentioned valve core 100, the first conducting channel 111 and the second conducting channel 112 are arranged at intervals on the valve core 100 to increase the flow path of the fluid, thereby facilitating the realization of multiple connectivity states of the multi-way valve 200. By arranging the first channel section 13 on the radial inner side of the second channel section 23, a double-layer channel is formed on the valve core 100, thereby improving the space utilization rate of the valve core 100 and facilitating the miniaturization design of the valve core 100. Thus, the miniaturization design of the multi-way valve 200 can be realized, saving the space required for arranging the multi-way valve 200 and helping to reduce the complexity of the structural design of the valve core 100.

[0130] In some embodiments of the present invention, the multi-way valve 200 includes a shell 210 and a first sealing member 220, an installation cavity 215 is formed in the shell 210, a valve port group 211 is provided on the shell 210, and the valve core 100 is rotatably arranged in the installation cavity 215 so that multiple groups of flow channel groups can be switched and connected with the valve port group 211. The first sealing member 220 is arranged between the shell 210 and the valve core 100, and is formed with multiple annular sealing portions 221, each annular sealing portion 221 surrounds the corresponding valve port 2111 of the valve port group 211.

[0131] Among them, the valve core 100 is provided with multiple groups of flow channel groups arranged at intervals along the circumferential direction, and the multiple groups of flow channel groups are suitable for switching and connecting with the valve port group 211 of the multi-way valve 200 to realize the switching of the connection state of the multi-way valve 200. In different connection states, different flow channel groups are correspondingly connected with the valve port group 211, and each group of flow channel groups 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.

[0132] Exemplarily, a valve port group 211 is formed on the shell 210 and is arranged along the radial direction through the shell 210, wherein the valve port group 211 includes two rows of valve ports 2111 arranged at intervals along the circumferential direction of the shell 210, and each row of valve ports 2111 includes multiple valve ports 2111 arranged along the axial direction of the shell 210.

[0133] Furthermore, 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 so that the valve port group 211 can be connected to different flow channel groups, thereby switching the connection state of the multi-way valve 200.

[0134] Furthermore, a mounting groove 214 is formed on the inner circumferential wall of the shell 210 and is arranged opposite to the valve port group 211 in the radial direction. The mounting groove 214 is recessed in the radial direction away from the central axis of the shell 210. The first sealing member 220 can be embedded in the mounting groove 214 so that the first sealing member 220 can be arranged between the valve core 100 and the shell 210.

[0135] Furthermore, a plurality of annular sealing portions 221 are formed on the first sealing member 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 perform a sealing function 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 cross-flow.

[0136] like Figure 1 As shown, in some embodiments of the present invention, the valve port group 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.

[0137] 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 connected to a plurality of first reinforcing ribs 212. By arranging a plurality of first reinforcing ribs 212 and a plurality of second reinforcing ribs 213 on the outer peripheral wall of the shell 210, and cross-arranging the first reinforcing ribs 212 and the second reinforcing ribs 213, the structural strength of the shell 210 is improved, and the protective effect of the shell 210 on the valve core 100 is ensured.

[0138] 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 group 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 group 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.

[0139] Reference Figure 1In 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 the actuator 400 is used to drive the valve core 100 to rotate in the mounting cavity 215, thereby switching the connectivity state of the multi-way valve 200.

[0140] 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.

[0141] The thermal management system 300 according to the embodiment of the present invention includes the multi-way valve 200 described above.

[0142] 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 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 heat pipe system; wherein the first heat exchanger can be used to exchange heat with the battery, and the second heat exchanger can be used to exchange heat with the vehicle cabin.

[0143] It can be understood that in each connection state of the multi-way valve 200, at least two valve ports 2111 participate in the circulation of the heat exchange medium. 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 conductive flow 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 conductive flow 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.

[0144] Since the thermal management system 300 is provided with the above-mentioned multi-way valve 200, the first conducting channel 111 and the second conducting channel 112 are arranged at intervals on the valve core 100 to increase the flow path of the fluid, which facilitates the realization of multiple connectivity states of the multi-way valve 200. By arranging the first channel section 13 on the radial inner side of the second channel section 23, a double-layer channel is formed on the valve core 100, which is beneficial to reducing the complexity of the structural design of the valve core 100 and improving the space utilization of the valve core 100, which is beneficial to the miniaturization design of the valve core 100, thereby realizing the miniaturization design of the multi-way valve 200 and saving the space required for arranging the multi-way valve 200, thereby realizing the miniaturization design of the thermal management system 300 and saving the space required for arranging the thermal management system 300. In addition, the multi-way valve 200 can realize more connectivity states than a three-way valve or a four-way valve, and there is no need to arrange multiple three-way valves or four-way valves in the thermal management system 300, which facilitates the control of the thermal management system 300 and helps reduce the production cost of the thermal management system 300.

[0145] In some embodiments of the present invention, the multi-way valve 200 also includes a second seal 250, which is located on the side of the valve port group 211 away from the central axis 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 the fluid (which can also be understood as the heat exchange medium) from leaking during the process of flowing from the external pipeline into the multi-way valve 200, thereby improving the sealing between the external pipeline and the multi-way valve 200.

[0146] Reference Figure 9 According to an embodiment of the present invention, the vehicle 1000 includes the multi-way valve 200 or the thermal management system 300 .

[0147] Since the vehicle 1000 is provided with the above-mentioned multi-way valve 200 or the above-mentioned thermal management system 300, the first conducting flow channel 111 and the second conducting flow channel 112 are arranged at intervals on the valve core 100 to increase the flow path of the fluid, so as to facilitate the realization of multiple communication states of the multi-way valve 200. By arranging the first flow channel section 13 on the radial inner side of the second flow channel section 23, a double-layer flow channel is formed on the valve core 100, which is conducive to reducing the complexity of the structural design of the valve core 100 and improving the space utilization of the valve core 100, which is conducive to realizing the miniaturization of the valve core 100. The multi-way valve 200 is designed to be miniaturized, thereby saving the space required for arranging the multi-way valve 200, which is conducive to realizing the miniaturized design of the thermal management system 300 and saving the space required for arranging the thermal management system 300. In addition, the multi-way valve 200 can realize more connectivity states than a three-way valve or a four-way valve, and there is no need to arrange multiple three-way valves or four-way valves in the thermal management system 300, which facilitates the control of the thermal management system 300 and is conducive to reducing the production cost of the thermal management system 300, thereby facilitating the lightweight design of the vehicle 1000.
