DETAILED DESCRIPTION

[0044] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0045] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will appreciate the applicability of other processes and / or the use of other materials.

[0046] Hereinafter, a multi-way valve 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0047] like Figure 1-Figure 3 and Figure 5-Figure 12 As shown, the multi-way valve 100 according to an embodiment of the present invention includes a housing 1 and a valve core 2, the housing 1 has multiple valve ports 1a, the multiple valve ports 1a include multiple inlets 1b and multiple outlets 1c, the multiple inlets 1b include a first inlet 111 and a second inlet 112; the valve core 2 is rotatably arranged in the housing 1, and the valve core 2 has multiple separated switching channels 2a.

[0048] The multi-way valve 100 has a first mode and a second mode. In the first mode, the first inlet 111 and the second inlet 112 are connected to the same outlet 1c through at least one switching channel 2a. The first mode has multiple first connection states. In different first connection states, the first inlet 111 is connected to different outlets 1c; in the second mode, the first inlet 111 and the second inlet 112 are connected to different outlets 1c through different switching channels 2a respectively. The second mode has multiple second connection states. In different second connection states, at least one of the first inlet 111 and the second inlet 112 is connected to a different outlet 1c.

[0049] It can be seen that in the first mode, no matter which first connection state they are in, the first inlet 111 and the second inlet 112 are both connected to one outlet 1c, and if the first inlet 111 and the second inlet 112 switch from the state of both being connected to one outlet 1c to the state of both being connected to another outlet 1c, it indicates that the multi-way valve 100 switches from one first connection state to another different first connection state; in the second mode, no matter which second connection state they are in, the first inlet 111 and the second inlet 112 are respectively connected to different outlets 1c, and if at least one of the first inlet 111 and the second inlet 112 switches to be connected to another outlet 1c while still making the first inlet 111 and the second inlet 112 respectively connected to different outlets 1c, it indicates that the multi-way valve 100 switches from one second connection state to another different second connection state. Then, if the number of outlets 1c is n, n is a positive integer greater than or equal to 2, then the number of first connection states is less than or equal to n, and the number of second connection states is less than or equal to the number of permutations A. n 2 (i.e. n*(n-1)).

[0050] Therefore, when the media at the first inlet 111 and the second inlet 112 need to have the same flow direction after passing through the multi-way valve 100, the multi-way valve 100 can be switched to the corresponding first connection state in the first mode according to the medium flow direction requirements at the first inlet 111 and the second inlet 112; when the media at the first inlet 111 and the second inlet 112 need to have different flow directions after passing through the multi-way valve 100, the multi-way valve 100 can be switched to the corresponding second connection state in the second mode according to the medium flow direction requirements at the first inlet 111 and the second inlet 112.

[0051] Obviously, through the rotational cooperation of the valve core 2 and the housing 1, the function of the reversing valve of the multi-way valve 100 can be realized. In the first mode, the first inlet 111 and the second inlet 112 can be switched to connect to the same outlet 1c, and the above-mentioned outlet 1c can be any at least two of the multiple outlets 1c, so that the multi-way valve 100 can switch between multiple first connection states; in the second mode, the first inlet 111 and the second inlet 112 can be switched to connect to different outlets 1c respectively, and at least one of the first inlet 111 and the second inlet 112 is different from the connected outlet 1c, so that the multi-way valve 100 can switch between multiple second connection states. Of course, the multi-way valve 100 can also switch between multiple first connection states and multiple second connection states. Therefore, the multi-way valve 100 has multiple connection states, and the multi-way valve 100 has a reversing function, which can realize the alternating switching of multiple connection states, making the switching mode of the multi-way valve 100 more diversified to adapt to different usage requirements and improve the applicability of the multi-way valve 100. Secondly, when the multi-way valve 100 is applied to the thermal management system 200, the setting of corresponding components (such as valves and pipelines, etc.) can be reduced, and an integrated layout can be realized, which is conducive to reducing costs and saving installation space. The thermal management system 200 can switch between multiple modes to meet more thermal management conditions.

[0052] For example, combined with Figure 3 、 Figure 5-Figure 12 and Figure 15 The multi-way valve 100 includes a shell 1 and a valve core 2. The shell 1 includes a bottom shell 11 and a cover plate 12. An open assembly cavity 1e is formed in the bottom shell 11. The valve core 2 is installed in the assembly cavity 1e. The cover plate 12 is installed in the bottom shell 11 and is used to close the open end of the assembly cavity 1e. The valve core 2 is configured to be rotatable relative to the shell 1. A driving member 5 is also installed on the cover plate 12. The output end of the driving member 5 is dynamically connected to the valve core 2, so that the driving member 5 can drive the valve core 2 to rotate around its own rotation axis, so that the multi-way valve 100 has a first mode and a second mode, and in different modes, the multi-way valve 100 has multiple communication states (a first communication state and a second communication state).

[0053] The bottom wall of the assembly cavity 1e of the housing 1 is provided with a plurality of valve ports 1a. These ports 1a are spaced apart along the circumference of the valve core 2, and each port 1a is axially opposed to the valve core 2. The valve core 2 has a plurality of switching flow channels 2a, which are spaced apart. The valve ports 1a can communicate with the switching flow channels 2a for circulating a medium. The plurality of valve ports 1a include a plurality of inlets 1b and a plurality of outlets 1c. The plurality of inlets 1b include a first inlet 111 and a second inlet 112. In a first mode, the first inlet 111 and the second inlet 112 communicate with the same outlet 1c via at least one switching flow channel 2a. The first mode has multiple first communication states, in which the first inlet 111 communicates with different outlets 1c. In a second mode, the first inlet 111 and the second inlet 112 communicate with different outlets 1c via different switching flow channels 2a. The second mode has multiple second communication states, in which at least one of the first inlet 111 and the second inlet 112 communicates with different outlets 1c.

[0054] Of course, the setting positions of the multiple valve ports 1a are not limited to this. For example, the multiple valve ports 1a can also be set on the side wall of the assembly cavity 1e of the shell 1, and the multiple valve ports 1a are arranged in sequence along the circumference of the valve core 2, and each valve port 1a is arranged opposite to the valve core 2 along the radial direction of the valve core 2; for another example, at least one of the multiple valve ports 1a is arranged on the bottom wall of the assembly cavity 1e of the shell 1, and the remaining valve ports 1a are arranged on the side wall of the assembly cavity 1a of the shell 1.

[0055] It should be noted that in the first mode, the first inlet 111 and the second inlet 112 are connected to the same outlet 1c through at least one switching channel 2a. For example, the first inlet 111 and the second inlet 112 can be connected to the same outlet 1c through one switching channel 2a or two switching channels 2a. Among them, when the first inlet 111 and the second inlet 112 can be connected to an outlet 1c through a switching channel 2a: in different first connection states, the first inlet 111 and the second inlet 112 can be connected to different outlets 1c through the same switching channel 2a, and / or, in the same first connection state, the first inlet 111 and the second inlet 112 can be connected to the same outlet 1c through different switching channels 2a, so as to realize switching of multiple first connection states by rotating the valve core 2; when the first inlet 111 and the second inlet 112 are respectively connected to the same outlet 1c through two switching channels 2a, that is, the first inlet 111 is connected to the above-mentioned outlet 1c through one switching channel 2a and the second inlet 112 is connected to the above-mentioned outlet 1c through another switching channel 2a, then each of the above-mentioned two switching channels 2a is respectively connected to a part of the above-mentioned outlet 1c.

[0056] It should be noted that there are two or more inlets 1b. During the rotation of the valve core 2, in the first mode, the first inlet 111 and the second inlet 112 are connected to the same inlet 1b through at least one switching channel 2a, and in different first connection states, the first inlet 111 is connected to different outlets 1c, so that the first mode has multiple first connection states; in the second mode, the first inlet 111 and the second inlet 112 are connected to different outlets 1c through different switching channels 2a respectively, and the second mode has multiple second connection states. In different second connection states, at least one of the first inlet 111 and the second inlet 112 is connected to different outlets 1c, so that the second mode has multiple second connection states.

[0057] For example, if Figure 5-Figure 12 As shown, the plurality of inlets 1b include a first inlet 111 and a second inlet 112, the plurality of outlets 1c include a first outlet 113, a second outlet 114, and a third outlet 115, and the plurality of switching channels 2a include a first switching channel 21, a second switching channel 22, and a third switching channel 23. In the first mode, the multi-way valve 100 has three first communication states. In the first first communication state, the first inlet 111 and the second inlet 112 are connected to the first outlet 113 via the first switching channel 21 or the second switching channel 22. In the second first communication state, the first inlet 111 and the second inlet 112 are connected to the second outlet 114 via the first switching channel 21 or the second switching channel 22. In the third first communication state, the first inlet 111 and the second inlet 112 are connected to the third outlet 115 via the third switching channel 23. In the second mode, the multi-way valve 100 has three second connection states. In the first second connection state, the first inlet 111 is connected to the first outlet 113 through the first switching channel 21, and the second inlet 112 is connected to the third outlet 115 through the third switching channel 23; in the second connection state, the first inlet 111 is connected to the third outlet 115 through the third switching channel 23, and the second inlet 112 is connected to the second outlet 114 through the second switching channel 22; in the third connection state, the first inlet 111 is connected to the first outlet 113 through the second switching channel 22, and the second inlet 112 is connected to the second outlet 114 through the third switching channel 23, or, the first inlet 111 is connected to the first outlet 113 through the third switching channel 23, and the second inlet 112 is connected to the second outlet 114 through the first switching channel 21.

[0058] The above embodiments are merely exemplary and do not limit the present invention. The present invention may also be configured to have two or more outlets 1c, and this application does not impose any limitation thereto. For example, the two outlets 1c are respectively a first outlet 113 and a second outlet 114. In the first mode, the first inlet 111 and the second inlet 112 may both be connected to the first outlet 113, and the first inlet 111 and the second inlet 112 may both be connected to the second outlet 114, so that the first mode has two first connection states; in the second mode, the first inlet 111 is connected to the first outlet 113, the second inlet 112 is connected to the second outlet 114, the first inlet 111 is connected to the second outlet 114, and the second inlet 112 is connected to the first outlet 113, so that the second mode has two second connection states.

[0059] In the above technical solution, by setting in the first mode, the first inlet 111 and the second inlet 112 can select one of the multiple different outlets 1c to switch and connect, so that the multi-way valve 100 has multiple first connection states, and the multi-way valve 100 can switch between multiple first connection states; in the second mode, the first inlet 111 and the second inlet 112 can be switched and connected with different outlets 1c respectively, and at least one of the first inlet 111 and the second inlet 112 is switched to connect with a different outlet 1c, so that the multi-way valve 100 has multiple second connection states, and the multi-way valve 100 can switch between multiple second connection states. As a result, the multi-way valve 100 has a reversing function, and the multi-way valve 100 can switch between multiple connection states (multiple first connection states and multiple second connection states), making the switching mode of the multi-way valve 100 more diversified to adapt to different usage requirements and improve the applicability of the multi-way valve 100.

[0060] Optionally, the opening areas of the inlet 1b and the outlet 1c are equal. For example, the inlet 1b and the outlet 1c are both formed as circular openings, and the opening diameters of the inlet 1b and the outlet 1c are both 15.8 mm.

[0061] Optionally, the valve core 2 has multiple switching flow channels 2a, and at least a portion of the cross-sectional shape of each switching flow channel 2a is a curved surface (e.g., a semicircular shape), thereby reducing the resistance of the medium when flowing in the switching flow channel 2a. For example, with reference to the figure, the switching flow channel 2a is formed by uniformly scanning a sphere, and the cross-sectional shape of the bottom wall of the switching flow channel 2a is a semicircular shape, which can reduce fluid resistance.

[0062] Optionally, a sealing rib is formed on the edge of the switching channel 2a, and the sealing rib can be interference fit with the corresponding seal (such as the first seal 3 below), which can improve the sealing performance of the dynamic seal between the valve core 2 and the corresponding seal.

[0063] In some embodiments of the present application, the multi-way valve 100 is configured to satisfy at least one of the following conditions: Condition A1, in at least two first connection states, the first inlet 111 is connected to different outlets 1c through the same switching channel 2a; Condition A2, one of the multiple switching channels 2a is a set channel, and in different second connection states, a corresponding one of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the set channel; Condition A3, in the first mode, the multiple switching channels 2a used to connect the corresponding valve ports 1a constitute a first set, and in the second mode, the multiple switching channels 2a used to connect the corresponding valve ports 1a constitute a second set, and the first set is a subset of the second set; Condition A4, the number of outlets 1c and the number of switching channels 2a are both three or more, and in any first connection state, except for the outlet 1c connected to the first inlet 111, the remaining multiple outlets 1c are separated by different switching channels 2a.

[0064] In some embodiments, as Figure 5-Figure 8 As shown, the multi-way valve 100 is constructed to meet condition A1. In at least two first connection states, the first inlet 111 is connected to different outlets 1c through the same switching channel 2a. There is at least one switching channel 2a that enables the multi-way valve 100 to achieve at least two first connection states, which is beneficial to reducing the number of switching channels 2a.

[0065] For example, the plurality of outlets 1c include a first outlet 113, a second outlet 114 and a third outlet 115. When the valve core 2 rotates to a certain angle position, the valve core 2 is connected to the valve core 2. Figure 8 The first inlet 111 and the second inlet 112 are both connected to the first outlet 113 through the first switching channel 21. When the valve core 2 rotates to another angular position, the valve core 2 is connected to the first outlet 113. Figure 6 , the first inlet 111 and the second inlet 112 are connected to the second outlet 114 through the first switching channel 21; and / or when the valve core 2 rotates to a certain angle position, combined with Figure 7 The first inlet 111 and the second inlet 112 are connected to the first outlet 113 through the second switching channel 22. When the valve core 2 rotates to another angular position, the first inlet 111 and the second inlet 112 are connected to the second outlet 114 through the second switching channel 22.

[0066] In some embodiments, as Figure 10-12As shown, the multi-way valve 100 is configured to meet condition A2, where one of the multiple switching flow channels 2a is a set flow channel. In different second communication states, a corresponding one of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the set flow channel. In different second communication states, the valve core 2 can connect the corresponding one of the first inlet 111 and the second inlet 112 to the corresponding outlet 1c through the set flow channel, so that the arrangement of the switching flow channels 2a can be flexible and varied, improving the practicality of the multi-way valve 100 and reducing the layout difficulty of the multi-way valve 100. It can be seen that in different second communication states, the above-mentioned set flow channels are all in an operating state to achieve the flow of the medium. The set flow channel can then cooperate with other switching flow channels 2a to achieve different second communication states, which is beneficial for reducing the number of switching flow channels 2a and simplifying the arrangement of multiple switching flow channels 2a.

[0067] For example, the multi-way valve 100 can be configured to: Figure 10 and Figure 12 As shown), the second inlet 112 (or the first inlet 111) is connected to different outlets 1c through a set flow channel. At this time, in the above two different second communication states, the first inlet 111 can be connected to the same outlet 1c; and / or, in two different second communication states (as shown), the second inlet 112 (or the first inlet 111) is connected to different outlets 1c through a set flow channel. Figure 10 and Figure 11 As shown), the same outlet 1c is connected to the first inlet 111 and the second inlet 112 by setting the flow channel switching, that is, in one of the second connection states, the outlet 1c is connected to the first inlet 111 through the set flow channel, and in the other second connection state, the outlet 1c is connected to the second inlet 112 through the set flow channel.

[0068] Further optionally, in all second connection states, the set flow channel is in a working state to realize the flow of the medium. Taking the second connection state as three as an example, in the first second connection state, the first inlet 111 is connected to the first outlet 113 through the first switching flow channel 21, and the second inlet 112 is connected to the third outlet 115 through the third switching flow channel 23; in the second connection state, the first inlet 111 is connected to the third outlet 115 through the third switching flow channel 23, and the second inlet 112 is connected to the second outlet 114 through the second switching flow channel 22; in the third connection state, the first inlet 111 is connected to the first outlet 113 through the second switching flow channel 22, and the second inlet 112 is connected to the second outlet 114 through the third switching flow channel 23, or the first inlet 111 is connected to the first outlet 113 through the third switching flow channel 23, and the second inlet 112 is connected to the second outlet 114 through the first switching flow channel 21; it can be seen that the third switching flow channel 23 is the set flow channel.

[0069] In some embodiments, the multi-way valve 100 is configured to satisfy condition A3: in the first mode, the plurality of switching channels 2a for connecting the corresponding valve port 1a constitute a first set, i.e., in all first connection states, all switching channels 2a that participate in connecting the inlet 1b (at least one of the first inlet 111 and the second inlet 112) with the corresponding outlet 1c constitute the first set; in the second mode, the plurality of switching channels 2a for connecting the corresponding valve port 1a constitute a second set, i.e., in all second connection states, all switching channels 2a that participate in connecting any one of the first inlet 111 and the second inlet 112 with the corresponding outlet 1c constitute the second set; the first set is a subset of the second set, and each switching channel 2a in the first set belongs to the second set. This helps reduce the number of switching channels 2a of the valve core 2, fully utilizes the channel space provided by the valve core 2, and reduces the complexity of the layout of the switching channels 2a.

[0070] For example, in combination Figure 5-Figure 12 The first mode has three first connection states. In the first first connection state, the first switching channel 21 or the second switching channel 22 connects the first inlet 111, the second inlet 112 and the first outlet 113. In the second first connection state, the first switching channel 21 or the second switching channel 22 connects the first inlet 111, the second inlet 112 and the second outlet 114. In the third first connection state, the third switching channel 23 connects the first inlet 111, the second inlet 112 and the third outlet 115. Then the first switching channel 21 and the third switching channel 23 can constitute a first set, or the second switching channel 22 and the third switching channel 23 constitute a first set, or the first switching channel 21, the second switching channel 22 and the third switching channel 23 constitute a first set. The second mode has three second connection states. In the first second connection state, the first switching channel 21 connects the first inlet 111 and the first outlet 113, and the third switching channel 23 connects the second inlet 112 and the second outlet 114, or the third switching channel 21 connects the first inlet 111 and the first outlet 113, and the second switching channel 22 connects the second inlet 112 and the second outlet 114; in the second second connection state, the third switching channel 21 connects the first inlet 111 and the third outlet 115, and the first switching channel 21 connects the second inlet 112 and the second outlet 114; in the third second connection state, the third switching channel 21 connects the second inlet 112 and the third outlet 115, and the second switching channel 22 connects the first inlet 111 and the first outlet 113, then the first switching channel 21, the second switching channel 22 and the third switching channel 23 constitute a second set.

[0071] In some embodiments, combined Figure 5The multi-way valve 100 is configured to satisfy condition A4: the number of outlets 1c and the number of switching channels 2a are both three or more. In any first connection state, except for the outlet 1c connected to the first inlet 111, the remaining outlets 1c are separated by different switching channels 2a, that is, the remaining outlets 1c are disconnected and not connected to each other. In any first connection state, all outlets 1c not connected to the first inlet 111 and the second inlet 112 are connected to different switching channels 2a, so that all outlets 1c not connected to the first inlet 111 and the second inlet 112 are separated from each other by the multiple switching channels 2a. When the multi-way valve 100 is used in the thermal management system 200, the channels connected to the remaining outlets 1c are also disconnected and not connected to each other, so as to ensure normal operation of the thermal management system 200.

[0072] For example, in combination Figure 5-Figure 9 , taking the case where there are three outlets 1c and the first mode has three first connection states as an example: in the first first connection state, any one of the first switching channel 21 and the second switching channel 22 is connected to the first inlet 111, the second inlet 112 and the first outlet 113, and the second outlet 114 and the third outlet 115 are respectively separated by the remaining switching channel 2a; in the second first connection state, any one of the first switching channel 21 and the second switching channel 22 is connected to the first inlet 111, the second inlet 112 and the second outlet 114, and the first outlet 113 and the third outlet 115 are respectively separated by the remaining switching channel 2a; in the third first connection state, the third switching channel 23 is connected to the first inlet 111, the second inlet 112 and the third outlet 115, and the first outlet 113 and the second outlet 114 are respectively separated by the first switching channel 21 and the second switching channel 22.

[0073] It should also be explained that the above-mentioned multi-way valve 100 is constructed to meet the following conditions: Condition A1, Condition A2, Condition A3 and Condition A4. Condition A1, Condition A2, Condition A3 and Condition A4 can be met individually, and any two combinations of the multiple conditions can be met, or any three combinations can be met, or any four combinations can be met, so that the settings of the valve port 1a and the switching channel 2a of the multi-way valve 100 are more diverse, which is conducive to the more flexible arrangement of the valve port 1a and the switching channel 2a, improves the practicality of the multi-way valve 100, and reduces the layout difficulty of the multi-way valve 100.

[0074] In the above technical solution, by setting the multi-way valve 100 to meet at least one of multiple conditions (such as condition A1, condition A2, condition A3 and condition A4), the settings of the valve port 1a and the switching channel 2a of the multi-way valve 100 are more diverse, which is conducive to the flexible arrangement of the valve port 1a and the switching channel 2a, thereby improving the practicality of the multi-way valve 100.

[0075] In some embodiments of the present application, Figure 3 and Figure 14 As shown, all valve ports 1a are located at one axial end of the shell 1, the switching channel 2a is open on the side facing the valve port 1a, and the switching channel 2a is closed on the side facing away from the valve port 1a, and the axial direction of the shell 1 is parallel to the extension direction of the rotation axis of the valve core 2.

[0076] For example, combined with Figure 3 and Figure 14 The housing 1 includes a bottom shell 11 and a cover plate 12. An open assembly cavity 1e is formed within the bottom shell 11. The bottom wall of the assembly cavity 1e is formed with multiple valve ports 1a. The valve core 2 is disc-shaped and rotatably disposed within the assembly cavity 1e. Multiple switching channels 2a are formed at the bottom end of the valve core 2, and the switching channels 2a are open toward the valve ports 1a. As a result, the switching channels 2a of the valve core 2 axially mate with the valve ports 1a of the housing 1, making the axial fit of the valve core 2 and the housing 1 relatively compact. Furthermore, by designing the structure of the valve core 2 and the position of the valve ports 1a, the overall volume of the valve core 2 and the housing 1 can be adaptively reduced (for example, the overall dimensions of the multi-way valve 100 are 128 mm × 130 mm × 78 mm). This allows the multi-way valve 100 to occupy a smaller space in the axial direction of the valve core 2 and achieve multiple modes with a smaller volume, thus meeting the requirements of a lightweight design.

[0077] In the above technical solution, by arranging all the valve ports 1a at one axial end of the shell 1, it is beneficial to reduce the axial length of the shell 1, and the switching channel 2a is opened on the side facing the valve port 1a, and the switching channel 2a is closed on the side facing away from the valve port 1a, so as to reduce the axial length of the valve core 2 on the premise of achieving switching connection between the valve port 1a and the corresponding switching channel 2a, thereby facilitating further reducing the axial length of the shell 1, reducing the axial size of the multi-way valve 100, and saving axial occupied space; it can be seen that the design of the valve core 2 structure and the valve port 1a position can adaptively reduce the overall volume of the valve core 2 and the shell 1, so that the multi-way valve 100 can achieve multiple modes with a smaller volume.

[0078] In some embodiments of the present application, Figure 15 As shown, all valve ports 1 a are located at one axial end of the housing 1 and are spaced apart along the circumference of the valve core 2 , and the centers of all valve ports 1 a are located on the same cylindrical surface.

[0079] In the above technical solution, by arranging all valve ports 1a at intervals along the circumference of valve core 2, with the centers of all valve ports 1a located on the same cylindrical surface, the distances between all valve ports 1a and the rotation axis of valve core 2 are equal, facilitating stable switching and communication between switching flow passages 2a and corresponding valve ports 1a during the rotational coordination of valve core 2 and housing 1. Furthermore, the centers of all valve ports 1a located on the same cylindrical surface simplify the arrangement and processing of valve ports 1a. Furthermore, valve ports 1a do not occupy the portion of housing 1 corresponding to the inner side of the cylindrical surface. Therefore, the portion of valve core 2 corresponding to the inner side of the cylindrical surface, where switching flow passages 2a are located, is less susceptible to being affected by valve ports 1a.

[0080] In the description of this application, "axial" can be understood as the axial direction of the valve core 2, that is, the extension direction of the rotation axis of the valve core 2; "radial" can be understood as the radial direction of the valve core 2, that is, the direction of the rotation axis of the valve core 2 in the radial plane, and the radial plane is perpendicular to the axial direction of the valve core 2; "circumferential" can be understood as the direction around the rotation axis of the valve core 2.

[0081] In some embodiments of the present application, Figure 15 As shown, the housing 1 includes a first portion 11a and a second portion 11b sequentially arranged along the circumference of the valve core 2, the first inlet 111 and the second inlet 112 are both formed on the first portion 11a, and all outlets 1c are formed on the second portion 11b.

[0082] For example, combined with Figure 3 and Figure 15 The housing 1 includes a bottom shell 11 and a cover plate 12. The bottom shell 11 includes a first portion 11a and a second portion 11b, which are sequentially arranged along the circumference of the valve core 2. The first portion 11a and the second portion 11b are each formed into a substantially fan-shaped structure. The first portion 11a is formed with a first inlet 111 and a second inlet 112, which are sequentially spaced apart along the circumference of the valve core 2. The second portion 11b is formed with a plurality of outlets 1c, which are sequentially spaced apart along the circumference of the valve core 2. Thus, the first inlet 111 and the second inlet 112 are spaced apart from all the outlets 1c along the circumference of the valve core 2, facilitating that the switching flow channel 2a of the valve core 2 connects to the corresponding inlet 1b and outlet 1c as the valve core 2 rotates, thereby enabling the multi-way valve 100 to have multiple connection states.

[0083] In the above technical solution, the first inlet 111 and the second inlet 112 are formed on the first part 11a, and all the outlets 1c are formed on the second part 11b, so that the first inlet 111 and the second inlet 112 are spaced from all the outlets 1c along the circumference of the valve core 2, so that the first inlet 111 and the second inlet 112 are arranged more concentratedly and all the outlets 1c are arranged more concentratedly, which facilitates the switching channel 2a of the valve core 2 to connect the corresponding inlet 1b and outlet 1c with the rotation of the valve core 2 to realize the first mode and the second mode, which is conducive to simplifying the arrangement of multiple switching channels 2a to a certain extent.

[0084] Optionally, combined Figure 3 and Figure 15 The housing 1 includes a bottom shell 11 and a cover plate 12. An open assembly cavity 1e is formed in the bottom shell 11. The cover plate 12 is detachably mounted on the housing 1 and is used to close the open end of the assembly cavity 1e. The bottom shell 11 includes an end cover and a side panel. The side panel is arranged around the edge of the end cover. The end cover defines the bottom wall of the assembly cavity 1e, and the side panel defines the side wall of the assembly cavity 1e. All valve ports 1a (such as the first inlet 111, the second inlet 112 and all outlets 1c) are formed on the end cover to facilitate the coordination and communication between the switching flow channel 2a of the valve core 2 and the valve port 1a. Optionally, the cover plate 12 is formed with a fixing hole (such as a self-tapping screw hole) to facilitate the fixing of the drive member 5. Optionally, the bottom shell 11 is provided with a reinforcing rib and a mounting hole to improve the structural strength of the bottom shell 11, and to dock and fix the multi-way valve 100 with the corresponding component (such as an integrated system) through the mounting hole.

[0085] In some embodiments of the present application, Figure 15 As shown, the number of outlets 1c is three or more, and the number of outlets 1c is greater than the number of inlets 1b. On a plane perpendicular to the rotation axis of the valve core 2, with the positive projection of the rotation axis of the valve core 2 as the center of the circle, the central angle corresponding to the first part 11a is smaller than the central angle corresponding to the second part 11b, and the circumferential spacing between two adjacent outlets 1c is greater than the circumferential spacing between two adjacent inlets 1b and outlets 1c.

[0086] In the above technical solution, by setting the number of outlets 1c to three or more, and by having the number of outlets 1c be greater than the number of inlets 1b, the multi-way valve 100 can have a wider range of connection states, which can better adapt to usage requirements. Secondly, by setting the circumferential spacing between two adjacent outlets 1c to be greater than the circumferential spacing between two adjacent inlets 1b and outlets 1c, the circumferential arrangement of the multiple outlets 1c on the valve core 2 is different from the circumferential arrangement of the two inlets 1b on the valve core 2. This facilitates the communication between the multiple switching channels 2a of the valve core 2 and the corresponding outlets 1c and inlets 1b, thereby realizing multiple modes of the valve core 2 (e.g., the first mode and the second mode).

[0087] In some embodiments of the present application, Figure 5-Figure 12 and Figure 14 As shown, multiple switching channels 2a include a first switching channel 21, a second switching channel 22 and a third switching channel 23. The first switching channel 21 and the second switching channel 22 both extend along the circumference of the valve core 2, and the third switching channel 23 is arranged between the first switching channel 21 and the second switching channel 22.

[0088] In the first mode, the first inlet 111 and the second inlet 112 are connected to the corresponding outlet 1c through any one of the first switching flow channel 21, the second switching flow channel 22 and the third switching flow channel 23. The first inlet 111 and the second inlet 112 can be connected to the corresponding outlet 1c (hereinafter referred to as the first outlet) through the first switching flow channel 21, the first inlet 111 and the second inlet 112 can be connected to the corresponding outlet 1c (hereinafter referred to as the second outlet) through the second switching flow channel 22, and the first inlet 111 and the second inlet 112 can be connected to a corresponding outlet 1c (hereinafter referred to as the third outlet) through the third switching flow channel 23. At this time, the first outlet and the second outlet are different from the third outlet respectively, and the first outlet can correspond to one outlet 1c or two different outlets 1c, the second outlet can correspond to one outlet 1c or two different outlets 1c, and the second outlet and the second outlet can be the same or different.

[0089] For example, if the first outlet and the second outlet are the same, the first switching channel 21 and the second switching channel 22 can be symmetrically arranged with respect to the third switching channel 23. Figure 6-Figure 8 As shown, the first outlet and the second outlet correspond to two different outlets 1c (i.e., the first outlet 113 and the second outlet 114), respectively. In a first connection state, the first inlet 111 and the second inlet 112 can be connected to the first outlet 113 through the first switching channel 21 or the second switching channel 22. In another first connection state, the first inlet 111 and the second inlet 112 can be connected to the second outlet 114 through the first switching channel 21 or the second switching channel 22.

[0090] In the second mode, one of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through one of the first switching channel 21 and the second switching channel 22, and the other of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the third switching channel 23. It can be seen that in each second connection state, the third switching channel 23 is connected to the corresponding inlet 1b and the corresponding outlet 1c, one of the first switching channel 21 and the second switching channel 22 is connected to the corresponding inlet 1b and the corresponding outlet 1c, and the other can be in an isolated state.

[0091] For example, combined with Figure 5-Figure 12 and Figure 14 The first switching channel 21 and the second switching channel 22 both extend along the circumference of the valve core 2, that is, the first switching channel 21 and the second switching channel 22 are extended along the rotation direction of the valve core 2, and the third switching channel 23 is arranged between the first switching channel 21 and the second switching channel 22. The shell 1 is arranged with two inlets 1b (a first inlet 111 and a second inlet 112) and three outlets 1c in sequence in the extension direction of the first switching flow channel 21. Any one of the first switching flow channel 21 and the second switching flow channel 22 can connect two inlets 1b and an outlet 1c adjacent to one of the above-mentioned two inlets 1b; any one of the first switching flow channel 21 and the second switching flow channel 22 can connect an adjacent inlet 1b and an outlet 1c, and the third switching flow channel 23 can connect two inlets 1b and an outlet 1c radially opposite thereto (for example, connecting the first inlet 111, the second inlet 112 and the third outlet 115), or connect one inlet 1b and an outlet 1c radially opposite thereto (for example, connecting the first inlet 111 and the third outlet 115, or connecting the second inlet 112 and the third outlet 115).

[0092] In the above technical solution, the first switching channel 21, the second switching channel 22 and the third switching channel 23 are arranged to connect the corresponding outlet 1c and the inlet 1b in the first mode or the second mode, so that the multi-way valve 100 has multiple connection states in the corresponding mode.

[0093] In some embodiments, combined Figure 5-Figure 12 and Figure 14 The plurality of outlets 1c include a first outlet 113, a second outlet 114, and a third outlet 115 that are spaced apart along the circumference of the valve core 2. The first outlet 113 is adjacent to the first inlet 111 and is located on a side of the first inlet 111 away from the second inlet 112. No other valve ports 1a are provided between the first outlet 113 and the first inlet 111. The second outlet 114 is adjacent to the second inlet 112 and is located on a side of the second inlet 112 away from the first inlet 111. No other valve ports 1a are provided between the second outlet 114 and the second inlet 112. a. The third outlet 115 is arranged between the first outlet 113 and the second outlet 114; the third switching channel 23 includes a first channel section 231, a second channel section 232 and a third channel section 233, and the third channel section 233 connects the first channel section 231 and the second channel section 232. In the circumferential direction of the valve core 2, the first channel section 231 and the second channel section 232 are respectively arranged between the first switching channel 21 and the second switching channel 22, and the first channel section 231 and the second channel section 232 are arranged opposite to each other along the radial direction of the valve core 2, and the circumferential length of the first channel section 231 is greater than the length of the second channel section 232.

[0094] In the first mode, the first inlet 111 is connected to the first outlet 113 or the second outlet 114 through either the first switching channel 21 or the second switching channel 22, and the first inlet 111 is connected to the third outlet 115 through the third switching channel 23, then the first mode can have at least three first connection states; in the second mode, the other one of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel section 231 (at this time, the other one of the first inlet 111 and the second inlet 112 and the corresponding outlet 1c can both be arranged opposite to the first channel section 231), or, the other one of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel section 231 and the second channel section 232 (at this time, the other one of the first inlet 111 and the second inlet 112 can be arranged opposite to the second channel section 232, and the corresponding outlet 1c can be arranged opposite to the first channel section 231). Therefore, it is convenient to enrich the communication states of the multi-way valve 100 , and as the valve core 2 rotates, the multi-way valve 100 can switch between multiple communication states to achieve the switching communication function of the multi-way valve 100 .

[0095] For example, combined with Figure 5-Figure 12 and Figure 14 A first inlet 111, a second inlet 112, a first outlet 113, a second outlet 114, and a third outlet 115 are formed at one axial end of the housing 1. The first outlet 113, the second outlet 114, and the third outlet 115 are equidistantly spaced along the circumference of the valve core 2. The centers of the first inlet 111, the second inlet 112, the first outlet 113, the second outlet 114, and the third outlet 115 are all located on the same cylindrical surface. The circumferential spacing between the first inlet 111 and the second inlet 112 is smaller than the circumferential spacing between the second outlet 114 and the third outlet 115. The circumferential spacing between the first inlet 111 and the second inlet 112 is equal to the circumferential spacing between the first inlet 111 and the first outlet 113, and is also equal to the circumferential spacing between the second inlet 112 and the second outlet 114. The valve core 2 is formed with a first switching flow channel 21, a second switching flow channel 22, and a third switching flow channel 23. The first switching flow channel 21 and the second switching flow channel 22 extend along the circumference of the valve core 2 and have equal extension lengths.

[0096] In the first mode, the first inlet 111 and the second inlet 112 can be connected to the first outlet 113 or the second outlet 114 via either the first switching channel 21 or the second switching channel 22. Alternatively, the first inlet 111 and the second inlet 112 are both connected to the first channel section 231, the third outlet 115 is connected to the second channel section 232, and the third channel section 233 is connected to the first channel section 231 and the second channel section 232. In this case, the first inlet 111 and the second inlet 112 are connected to the third outlet 115 via the third switching channel 23. Thus, in the first mode, the multi-way valve 100 has three first connection states. As the valve core 2 rotates, one of the first switching channel 21, the second switching channel 22, and the third switching channel 23 connects the two inlets 1b (the first inlet 111 and the second inlet 112) and the corresponding outlet 1c, thereby enabling the multi-way valve 100 to switch between the three first connection states.

[0097] In the second mode, the first inlet 111 and the first outlet 113 are connected through the first switching flow channel 21, and the second inlet 112 and the second outlet 114 are connected through the first flow channel section 231, that is, the second inlet 112 and the second outlet 114 are connected through the third switching flow channel 23, or the first inlet 111 and the first outlet 113 are connected through the first flow channel section 231, that is, the first inlet 111 and the first outlet 113 are connected through the third switching flow channel 23, and the second inlet 112 and the second outlet 114 are connected through the second switching flow channel 22; or Alternatively, the second inlet 112 and the second outlet 114 are connected through the first switching channel 21, the third outlet 115 is connected through the first channel section 231, and the first inlet 111 is connected through the second channel section 232, that is, the second inlet 112 and the third outlet 115 are connected through the third switching channel 23. Thus, in the second mode, the multi-way valve 100 has three second communication states. As the valve core 2 rotates, two of the first switching channel 21, the second switching channel 22, and the third switching channel 23 are respectively connected to one of the two inlets 1b (the first inlet 111 and the second inlet 112) and the corresponding outlet 1c, thereby enabling the multi-way valve 100 to switch between the three second communication states.

[0098] Of course, as the valve core 2 rotates, the multi-way valve 100 can switch between the three first communication states and the three second communication states to achieve the switching communication function of the multi-way valve 100.

[0099] In some embodiments of the present application, Figure 10The centers of all valve ports 1a are located on the same cylindrical surface. The cylindrical surface has nine reference points 5 equidistantly spaced along the circumference of the valve core 2. These nine reference points 5 are sequentially arranged along the circumference of the valve core 2, namely, a first reference point 51 through a ninth reference point 59. The first reference point 51 through the fourth reference point 54 correspond to the centers of the first outlet 113, the first inlet 111, the second inlet 112, and the second outlet 114, respectively. The seventh reference point 57 corresponds to the center of the third outlet 115. On a plane perpendicular to the rotation axis of the valve core 2, the orthographic projections of the first switching flow channel 21 and the second switching flow channel 22 are each configured to cover the projections of three reference points 5. The orthographic projection of the first flow channel segment 231 is configured to cover the orthographic projection of one reference point 5, and the orthographic projection of the second flow channel segment 232 is configured to cover the orthographic projections of two reference points 5. In this case, all valve ports 1a can be located at one axial end of the housing 1.

[0100] It can be seen that the circumferential distance between the center of the first outlet 113 and the center of the first inlet 111, the circumferential distance between the center of the first inlet 111 and the center of the second inlet 112, and the circumferential distance between the center of the second outlet 114 and the center of the second inlet 112 are equal to each other, the circumferential distance between the center of the first outlet 113 and the center of the third outlet 115 is equal to the circumferential distance between the center of the first outlet 113 and the center of the third outlet 115, and the circumferential distance between the center of the first outlet 113 and the center of the third outlet 115 is twice the circumferential distance between the center of the first outlet 113 and the center of the first inlet 111; on a plane perpendicular to the rotation axis of the valve core 2, with the orthographic projection of the rotation axis of the valve core 2 as the center of the circle, the central angles corresponding to the first switching channel 21 and the second switching channel 22 are both greater than 80°, and the central angle corresponding to the first channel section 231 is greater than 40°. Therefore, by setting the arrangement of all valve ports 1a on the housing 1 and the corresponding relationship between the switching channels 2a and the valve ports 1a, the corresponding switching channels 2a can connect two or three valve ports 1a, so that the multi-way valve 100 has multiple connection states.

[0101] Combine Figure 10On a plane perpendicular to the rotation axis of the valve core 2, when the valve core 2 rotates to a certain angular position, the orthographic projection of the first switching channel 21 and the orthographic projection of the second switching channel 22 can cover the projections of three valve ports 1a that are adjacent in sequence and have equal circumferential distances (for example, covering the first inlet 111, the second inlet 112 and the first outlet 113, or covering the first inlet 111, the second inlet 112 and the second outlet 114, etc.), the orthographic projection of the first channel section 231 can cover the orthographic projections of any two valve ports 1a that are adjacent in sequence and have equal circumferential distances (for example, covering the first inlet 111 and the second inlet 112, or covering the first inlet 111 and the first outlet 113, or covering the second inlet 112 and the second outlet 114, etc.), and the orthographic projection of the second channel section 232 can cover the orthographic projection of one valve port 1a (for example, covering the third outlet 115, covering the second outlet 114, covering the second inlet 112, covering the first inlet 111, or covering the first outlet 113). Thus, the corresponding switching flow channel 2a can be connected to two or three valve ports 1a, so that the multi-way valve 100 has multiple communication states.

[0102] It can be seen that on the plane perpendicular to the rotation axis of the valve core 2, with the orthographic projection of the rotation axis of the valve core 2 as the center of the circle, the central angle corresponding to the centers of any two adjacent ones of the first outlet 113, the first inlet 111, the second inlet 112 and the second outlet 114 is 40°, and the central angle corresponding to the centers of any two adjacent ones of the first outlet 113, the second outlet 114 and the third outlet 115 is 120°.

[0103] For example, combined with Figure 3 and Figure 13 As shown, a stop point rib 2d is provided on the shell 1 (for example, the cover plate 12) and the valve core 2, respectively, so that the stop point rib 2d on the shell 1 and the stop point rib 2d of the valve core 2 are configured to form an end-stop structure (end-stop structure), which can be used as the starting position when the valve core 2 rotates, that is, the valve core 2 rotates to switch the multi-way valve 100 to the angle corresponding to the first connection state or the second connection state with the above-mentioned starting position as a reference, that is, when the stop point rib 2d of the valve core 2 stops with the single point rib 2d of the shell 1, the valve core 2 is in the 0° position, which is convenient for switching different connection states of the multi-way valve 100 by driving the valve core 2 to rotate the corresponding angle, so as to accurately adjust the connection state of the multi-way valve 100.

[0104] In the first mode, the multi-way valve 100 has three first communication states. In the first first communication state, Figure 5 and Figure 6 As shown, the first inlet 111, the second inlet 112 and the second outlet 114 are connected, and the first outlet 113 and the third outlet 115 are closed. At this time, the valve core 2 rotates clockwise to 5° or 165°; in the second first connection state, as shown Figure 7 and Figure 8 As shown, the first inlet 111, the second inlet 112 and the first outlet 113 are connected, and the second outlet 114 and the third outlet 115 are closed. At this time, the valve core 2 rotates to 205°; in the third first connection state, as shown Figure 9 As shown, the first inlet 111, the second inlet 112 and the third outlet 115 are connected, and the first outlet 113 and the second outlet 114 are closed. At this time, the valve core 2 rotates to 285 degrees.

[0105] In the second mode, the multi-way valve 100 has three second communication states. In the first second communication state, Figure 11 As shown, the first inlet 111 is connected to the third outlet 115, the second inlet 112 is connected to the second outlet 114, and the first outlet 113 is closed. At this time, the valve core 2 rotates to 125 degrees; in the second second connection state, as shown Figure 10 As shown, the first inlet 111 is connected to the first outlet 113, the second inlet 112 is connected to the third outlet 115, and the second outlet 114 is closed. At this time, the valve core 2 rotates to 85 degrees; in the third second connection state, as shown Figure 12 As shown, the first inlet 111 is connected to the first outlet 113 , the second inlet 112 is connected to the second outlet 114 , and the third outlet 115 is closed. At this time, the valve core 2 rotates to 245°.

[0106] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the multi-way valve 100 also includes a first sealing member 3, which is arranged at multiple valve ports 1a and is located between the housing 1 and the valve core 2. The first sealing member 3 is provided with multiple avoidance holes 31, and a limiting protrusion 32 is formed on the periphery of each avoidance hole 31. A first matching groove 1d arranged around the valve port 1a is formed on the outer peripheral side of each valve port 1a, and the multiple limiting protrusions 32 are respectively sealed and matched with the multiple first matching grooves 1d in a one-to-one manner. The other parts of the first sealing member 3 except the avoidance holes 31 separate the valve core 2 from the housing 1.

[0107] Optionally, the first sealing member 3 is a rubber member or the like.

[0108] For example, combined with Figure 2 and Figure 3The first sealing member 3 is formed with five avoidance holes 31 arranged in sequence along the circumference of the valve core 2. A limiting protrusion 32 is formed on the circumference of each avoidance hole 31 toward the side of the shell 1. The limiting protrusion 32 is formed into a raised circular ring structure. Five valve ports 1a are formed on the end face of one side of the shell 1. The five valve ports 1a are respectively a first inlet 111, a second inlet 112 and three outlets 1c. A first matching groove 1d arranged around the valve port 1a is formed on the outer peripheral side of each valve port 1a. The five limiting protrusions 32 correspond to the five valve ports 1a one by one; when the first sealing member 3 is arranged between the shell 1 and the valve core 2, each limiting protrusion 32 of the first sealing member 3 is sealed and matched with the corresponding first matching groove 1d to achieve sealing between the shell 1 and the valve core 2, thereby improving the sealing between the valve core 2 and the shell 1.

[0109] Optionally, the first sealing member 3 is interference-fitted between the valve core 2 and the housing 1 , which is beneficial to further improve the sealing between the valve core 2 and the first sealing member 3 , thereby improving the sealing between the valve core 2 and the housing 1 .

[0110] In the above technical solution, by providing a first sealing member 3 between the housing 1 and the valve core 2, the sealing between the housing 1 and the valve core 2 can be improved, that is, dynamic sealing is achieved during the rotation of the valve core 2 relative to the housing 1, and static sealing is achieved when the multi-way valve 100 is in a certain connected state. Secondly, a limiting protrusion 32 is formed on the periphery of each avoidance hole 31, and each limiting protrusion 32 is sealed with the first matching groove 1d at the corresponding valve port 1a, which can further improve the sealing between the first sealing member 3 and the housing 1, that is, the sealing of the connecting channel between the avoidance hole 31 and the valve port 1a. At the same time, the limiting protrusion 32 is sealed with the first matching groove 1d, which can limit the first sealing member 3 from rotating with the valve core 2, and to a certain extent avoid the formation of a gap between the first sealing member 3 and the housing 1 or the first sealing member 3 and the valve core 2, etc., which is beneficial to improving the sealing between the housing 1 and the valve core 2.

[0111] Optionally, combined Figure 3 and Figure 4 A third matching groove arranged around the valve port 1a is formed on the outer peripheral side of each valve port 1a toward the side away from the valve core 2. The multi-way valve also includes a third sealing member 6. Multiple third sealing members 6 correspond one-to-one to multiple third matching grooves to achieve sealing when the multi-way valve 100 is matched with other structures such as flanges.

[0112] In some embodiments of the present application, Figure 2 、 Figure 3 and Figure 13As shown, the multi-way valve 100 also includes a second sealing member 4, the valve core 2 has a pivot shaft 24, the inner wall of the shell 1 has an annular matching rib 13, the second sealing member 4 is arranged between the pivot shaft 24 and the matching rib 13, the valve core 2 also has a second matching groove 2b arranged around the pivot shaft 24, and the matching rib 13 is matched with the inner side of the outer peripheral wall of the second matching groove 2b.

[0113] For example, combined with Figure 2 and Figure 3 The housing 1 includes a bottom shell 11 and a cover plate 12. An open assembly chamber 1e is formed in the bottom shell 11. The valve core 2 is rotatably arranged in the assembly chamber 1e. The cover plate 12 closes the open end of the assembly chamber 1e. The valve core 2 has a pivot shaft 24. The end of the pivot shaft 24 is formed as a spline structure. A driving member 5 is also installed on the cover plate 12. The output end of the driving member 5 is connected to the spline structure of the valve core 2, so that the driving member 5 can drive the valve core 2 to rotate around its own rotation axis; the other end of the pivot shaft 24 stops at the bottom wall of the assembly chamber 1e, thereby improving the rotation stability of the valve core 2.

[0114] Among them, an annular mating rib 13 is formed on the side of the cover plate 12 facing the bottom shell 11, and the side of the valve core 2 facing the cover plate 12 has a pivot shaft 24, and the valve core 2 also has a second mating groove 2b arranged around the pivot shaft 24. When the cover plate 12 is mated with the bottom shell 11, the second sealing member 4 is arranged between the pivot shaft 24 and the mating rib 13, and the mating rib 13 is located in the second mating groove 2b, and the mating rib 13 is on both sides of the radial direction of the valve core 2, respectively mating with the inner side of the outer peripheral wall of the second mating groove 2b and the outer peripheral wall of the second sealing member 4, so as to realize dynamic sealing between the valve core 2 and the cover plate 12, thereby ensuring the sealing of the multi-way valve 100.

[0115] Optionally, a welding rib is formed on the edge of the open end of the bottom shell 11. The welding rib is used to cooperate with the welding groove of the cover plate 12 to facilitate welding of the bottom shell 11 and the cover plate 12, thereby achieving high sealing performance and compressive strength between the bottom shell 11 and the cover plate 12. In the radial direction of the valve core 2, the width of the welding groove is greater than the width of the welding rib. For example, the width of the welding rib is 1.3 mm and the width of the welding groove is 2.5 mm.

[0116] Optionally, the bottom shell 11 is made of a light-absorbing material and the cover plate 12 is made of a light-transmitting material, which facilitates laser welding of the bottom shell 11 and the cover plate 12. For example, the bottom shell 11 is injection-molded from a light-absorbing material and the cover plate 12 is injection-molded from a light-transmitting material.

[0117] In the above technical solution, by arranging the second sealing member 4 between the pivot shaft 24 and the mating rib 13, and the mating rib 13 being mated with the inner side of the outer peripheral wall of the second mating groove 2b, the sealing between the valve core 2 and the cover plate 12 can be achieved, thereby ensuring the sealing of the multi-way valve 100 and facilitating the reliable limiting of the second sealing member 4.

[0118] In some embodiments of the present application, Figure 2 As shown, an annular mating protrusion 2c is provided on the bottom wall of the second mating groove 2b. The mating protrusion 2c is spaced apart from the outer peripheral wall of the second mating groove 2b and the mating protrusion 2c is mated with the inner side of the mating rib 13. The mating protrusion 2c is used to limit the axial movement of the second sealing member 4 in the valve core 2.

[0119] In the above technical solution, by setting a matching protrusion 2c to limit the axial movement of the second sealing member 4 in the valve core 2, it is possible to avoid, to a certain extent, the failure of the seal between the valve core 2 and the cover plate 12 caused by the rotation of the valve core 2 of the second sealing member 4, which is beneficial to improving the reliability of the seal between the valve core 2 and the cover plate 12.

[0120] In a second aspect, an embodiment of the present application provides a thermal management system 200 , comprising the multi-way valve 100 of the embodiment of the first aspect described above.

[0121] In the above technical solution, by adopting the above multi-way valve 100 , the layout of the thermal management system 200 can be simplified, which is conducive to realizing the integrated layout of the thermal management system 200 .

[0122] In some embodiments of the present application, Figure 16 The plurality of outlets 1c include a first outlet 113, a second outlet 114 and a third outlet 115 which are spaced apart along the circumferential direction of the valve core 2. The first outlet 113 is adjacent to the first inlet 111 and is located on the side of the first inlet 111 away from the second inlet 112. The second outlet 114 is adjacent to the second inlet 112 and is located on the side of the second inlet 112 away from the first inlet 111. The third outlet 115 is arranged between the first outlet 113 and the second outlet 114. The third switching channel 23 includes a first channel section 231, a second channel section 232 and a third channel section 233. The third channel section 233 connects the first channel section 231 and the second channel section 232. In the circumferential direction of the valve core 2, the first channel section 231 and the second channel section 232 are respectively spaced apart between the first switching channel 21 and the second switching channel 22 and are arranged opposite to each other along the radial direction of the valve core 2. The circumferential length of the first channel section 231 is greater than the length of the second channel section 232.

[0123] In the first mode, the first inlet 111 is connected to the first outlet 113 or the second outlet 114 through either the first switching channel 21 or the second switching channel 22, and the first inlet 111 is connected to the third outlet 115 through the third switching channel 23; in the second mode, the other of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel section 231, or the other of the first inlet 111 and the second inlet 112 is connected to the corresponding outlet 1c through the first channel section 231 and the second channel section 232.

The temperature regulating capability of the first temperature regulating element 106 is different from that of the second temperature regulating element 107. The first flow path 101 is used to regulate the temperature of the motor 109, and the second flow path 102 is used to regulate the temperature of the battery pack 110; the first inlet 111 is connected to the downstream end of the second flow path 102, the second inlet 112 is connected to the downstream end of the first flow path 101, the first outlet 113 is connected to the upstream end of the fifth flow path 105, the second outlet 114 is connected to the upstream end of the fourth flow path 104, and the third outlet 115 is connected to the upstream end of the third flow path 103. In the first mode, any one of the first outlet 113 , the second outlet 114 and the third outlet 115 is connected to the first inlet 111 . In the second mode, any two of the first outlet 113 , the second outlet 114 and the third outlet 115 are connected to the first inlet 111 and the second inlet 112 respectively.

[0125] For example, combined with Figure 5-Figure 12 and Figure 16 Thermal management system 200 includes three switching assemblies 108, each configured as a three-way valve. The three three-way valves are a first three-way valve, a second three-way valve, and a third three-way valve. The first three-way valve connects to the downstream end of fourth flow path 104, the downstream end of third flow path 103 via the second three-way valve, and the upstream end of second flow path 102 via the second and third three-way valves. The second three-way valve connects the first three-way valve, the third three-way valve, and the downstream end of third flow path 103. The third three-way valve connects the second three-way valve, the downstream end of fifth flow path 105, and the upstream end of second flow path 102. Water pumps are connected in series to first flow path 101 and second flow path 102, respectively. First thermostat 106 is a refrigeration device, such as an evaporator with a refrigerant flow path inside. Second thermostat 107 is an air-cooled radiator.

[0126] In the first first connection state, the first inlet 111 and the second inlet 112 are connected to the first outlet 113 through the first switching channel 21 or the second switching channel 22, so the first flow path 101 and the fifth flow path 105 form a loop, and the second flow path 102 and the fifth flow path 105 form a loop; in the second first connection state, the first inlet 111 and the second inlet 112 are connected to the second outlet 114 through the first switching channel 21 or the second switching channel 22, so the first flow path 101 and the fourth flow path 104 form a loop. loop, the second flow path 102 and the fourth flow path 104 form a loop, and the second temperature regulating component 107 works to regulate the temperature of the battery pack 110 and the motor 109; in the third first connected state, the first inlet 111 and the second inlet 112 are connected to the third outlet 115 through the third switching channel 23, then the first flow path 101 and the third flow path 103 form a loop, the second flow path 102 and the third flow path 103 form a loop, and the first temperature regulating component 106 works to regulate the temperature of the battery pack 110 and the motor 109.
