In some modes, multiple cooling medium circuits may be connected in parallel with each other, while in other operating conditions, they may be connected in series with each other. Therefore, multi-way valves are needed for regulation. However, the large number of cooling medium circuits and the complexity of control result in complex structures and high costs for multi-way valves, making it difficult to achieve efficient thermal management.

[0048] For vehicles, especially pure electric and hybrid vehicles, the stable and efficient operation of the thermal management system can ensure stable and reliable operation and improve safety.

[0049] A thermal management system needs to at least manage the thermal of the battery, motor, engine, and passenger compartment. Some vehicle thermal management systems can also manage the temperature of the onboard refrigerator, recover and reuse engine waste heat, recover and reuse motor waste heat, and recover and reuse battery waste heat.

[0050] Specifically, battery thermal management can include cooling the battery when the battery temperature is high to prevent thermal runaway and potential safety risks caused by overheating. In low-temperature environments, the system may need to preheat the battery to maintain its charging and discharging efficiency, while ensuring battery life and driving safety. Engine and motor thermal management can include engine cooling and motor cooling. Engine waste heat, motor waste heat, and battery waste heat can be used to regulate the temperature of the passenger compartment. Of course, the battery can also be heated by engine waste heat, motor waste heat, etc. This application will not elaborate on them one by one.

[0051] Understandably, a thermal management system can coordinate the flow of multiple cooling medium circuits and their interconnections, and needs to manage the overall thermal state of the vehicle in a refined manner to ensure that the aforementioned components can operate stably and efficiently.

[0052] However, existing thermal management systems require the installation of numerous valve structures to achieve interconnection and on / off control between multiple cooling medium circuits, resulting in a complex overall structure. In particular, the complexity of multi-way valves or multiple valve bodies increases not only the difficulty of layout and cost but also makes it difficult to achieve efficient and precise geothermal management.

[0053] Based on this, this application proposes a multi-way valve. The multi-way valve has a simple structure, high reliability, and lower difficulty in interconnecting and controlling the on / off states of multiple cooling medium circuits. It can ensure the stable and efficient operation of the thermal management system and realize refined thermal management of the entire vehicle.

[0054] The following is for reference. Figures 1-10 The present invention describes a multi-way valve 10, a thermal management system 100, and a vehicle 1000 according to embodiments of the present invention.

[0055] This application provides a multi-way valve 10, including: valve core 11 and valve body 12.

[0056] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, there are multiple valve cores 11, which are stacked in a first direction and can all rotate in a second direction. A valve body 12 is sleeved on the multiple valve cores 11, and the valve body 12 is provided with multiple connecting parts 121 for connecting external components. The multiple connecting parts 121 are arranged at intervals along the first or second direction. Each valve core 11 includes multiple chambers a, and the first part of the chambers a is constructed as a closed chamber a2, and the second part of the chambers a is constructed as a connecting chamber a1. The connecting chamber a1 has a first connecting hole 114, and at least some of the chambers a have a second connecting hole 115. The first connecting hole 114 can be selectively connected to any connecting part 121, and the second connecting hole 115 is used to selectively connect to any chamber a of an adjacent valve core 11.

[0057] Specifically, each valve core 11 has multiple equally spaced chambers a, including a portion of a connecting chamber a1 and a portion of a closed chamber a2. When the connecting portion 121 of the valve body 12 is opposite to the connecting chamber a1, the connecting portion 121 is connected to the first connecting hole 114 of the connecting chamber a1, so that the cooling medium in the connecting portion 121 can flow to the connecting chamber a1, or the cooling medium in the connecting chamber a1 can flow to the connecting portion 121. When the connecting portion 121 is opposite to the closed chamber a2, the connecting portion 121 and the closed chamber a2 are in a cut-off state, and the cooling medium cannot flow between them.

[0058] It should be noted that multiple chambers a are spaced at equal angles, such as 30° or 60°. Adjacent chambers a can be connected or separated.

[0059] Multiple valve cores 11 are stacked in a first direction and can rotate in a second direction, such that in two adjacent valve cores 11, the chamber a of one valve core 11 can be selectively connected to the chamber a of another valve core 11, such as the connecting chamber a1 of one valve core 11 being connected to the closed chamber a2 of another valve core 11, or the connecting chamber a1 of one valve core 11 being connected to the connecting chamber a1 of another valve core 11. When the connecting chamber a1 of one valve core 11 is connected to the connecting chamber a1 of another valve core 11, the cooling medium can be connected between the two connecting chambers a1.

[0060] The first direction is the stacking direction of the valve core 11, that is, the axial direction of the valve core 11, while the second direction corresponds to the circumferential direction of the valve core 11.

[0061] Furthermore, when the connecting cavity a1 on one valve core 11 is connected to the connecting cavity a1 on another valve core 11 through the second connecting hole 115, and the first connecting holes 114 of the two connecting cavities a1 are respectively connected to a connecting part 121 through each other's first connecting holes 114, the two connecting parts 121 can be connected through the multi-way valve 10 of this application embodiment. When one connecting cavity a1 is connected to a closed cavity a2, and the connecting cavity a1 is directly opposite to a connecting part 121, and the closed cavity a2 is directly opposite to another connecting part 121, the two connecting parts 121 can be cut off. Alternatively, when the two closed cavities a2 are directly opposite the two connecting parts 121, the two connecting parts 121 can also be cut off.

[0062] For example, the valve core 11 includes a first valve core 11a and a second valve core 11b, while Figure 5 This diagram shows the first valve core 11a, the second valve core 11b, and the connecting portion 121 in one position. Figure 6 A schematic diagram is shown with the first valve core 11a, the second valve core 11b, and the connecting portion 121 in another position. A large frame without cross-section indicates the connecting cavity a1, a large frame with cross-section indicates the closed cavity a2, circles indicate the connecting portion 121, small frames with cross-section indicate adjacent chambers a on the same valve core 11 are separated, and small frames without cross-section indicate adjacent chambers a on the same valve core 11 are connected. From left to right in the diagram, the first valve core 11a has chambers 01 to 08, and the second valve core 11b has chambers 09 to 016.

[0063] See Figure 5 As shown, three of the multiple connecting portions 121 (e.g., six, eight, etc.) on the valve body 12 participate in the supply of cooling medium. Two of these connecting portions 121 are connected to the third chamber 03 and the fourth chamber 04 on the first valve core 11a, respectively, and both the third chamber 03 and the fourth chamber 04 are configured as connecting chambers a1. One connecting portion 121 is connected to the twelfth chamber 012 on the second valve core 11b, and the twelfth chamber 012 is also configured as connecting chamber a1, allowing the cooling medium to flow between the third chamber 03, the fourth chamber 04, and the twelfth chamber 012. (See also...) Figure 6As shown, four of the multiple connecting parts 121 (such as six or eight) on the valve body 12 participate in the supply of cooling medium. Among them, two connecting parts 121 are connected to the sixth chamber 06 and the seventh chamber 07 adjacent to each other on the first valve core 11a. The sixth chamber 06 and the seventh chamber 07 are both constructed as connecting chambers a1, and the sixth chamber 06 and the seventh chamber 07 are spaced apart. The seventh chamber 07 is connected to the eighth chamber 08. The two connecting parts 121 are connected to the fourteenth chamber 014 and the sixteenth chamber 016 on the second valve core 11b, respectively. The fourteenth chamber 014 and the sixteenth chamber 016 are both constructed as connecting chambers a1, and they are spaced apart. Thus, the sixth chamber 06 can be connected to the fourteenth chamber 014, and the seventh chamber 07 can be connected to the sixteenth chamber 016 (i.e., connected through the second connecting hole 115).

[0064] It should be noted that at least some chambers a have the second connecting hole 115, which means that all connecting chambers a1 have the second connecting hole 115, and at least some or all of the closed chambers a2 may also have the second connecting hole 115. The closed chamber a2 with the second connecting hole 115 can not only cut off the valve core 11 it is located in from the connecting part 121, but also supply cooling medium to the adjacent valve core 11 through the closed chamber a2. It can also realize the cross-valve core 11 communication of cooling medium, and can realize the selective switching of one or both of the two cooling medium flow paths being open.

[0065] According to the embodiments of this application, the multi-way valve 10 is provided with multiple stacked valve cores 11, each valve core 11 having multiple chambers a, and adjacent valve cores 11 can be selectively connected. Each valve core 11 can rotate relative to the valve body 12, and the multiple valve cores 11 can rotate synchronously or individually, so that the connecting part 121 on the valve body 12 can be selectively connected to or cut off from the corresponding chamber a. This makes it easier to control the connection relationship of multiple components connected to the connecting part 121, realizes fine control, and is conducive to the stable and efficient operation of the thermal management system 100. Moreover, the overall structure of the multi-way valve 10 is simpler, the degree of integration is higher, and the cost is lower.

[0066] Combination Figure 1 , Figure 2 and Figure 3 As shown, according to some embodiments of this application, the valve core 11 includes: a first partition 111, which is spaced apart in a second direction to divide the valve core 11 into a plurality of chambers a arranged at angles.

[0067] Specifically, there can be multiple chambers a. By setting the first partition 111, multiple chambers a can be spaced out in the valve core 11. This not only allows for the spaced arrangement of multiple chambers a, but also improves the structural strength of the valve core 11 and reduces the probability of deformation of chambers a when the cooling medium pressure is high. This makes the flow of the cooling medium in the chambers a more stable, and the reliability and stability of the valve core 11 and the multi-way valve 10 are higher.

[0068] Furthermore, it is understandable that by adjusting the number of the first partition 111, the number of chambers a can be adjusted, and the adaptability of the multi-way valve 10 can also be improved.

[0069] like Figure 1 , Figure 2 and Figure 3 As shown, according to some embodiments of this application, the valve core 11 further includes a second partition 112, which is located at at least one end of the valve core 11 in a first direction, and a second connecting hole 115 is provided on the second partition 112.

[0070] Specifically, at least one end of the plurality of first partitions 111 in the first direction is provided with a second partition 112. For example, if there are two valve cores 11, the lower end of one valve core 11 is provided with a second partition 112 and the upper end of the other valve core 11 is provided with a second partition 112. If there are three valve cores 11, the lower end of the uppermost valve core 11 is provided with a second partition 112 and the upper end of the lowermost valve core 11 is provided with a second partition 112, while both ends of the middle valve core 11 are provided with second partitions 112.

[0071] The second partition 112 is generally disc-shaped or annular, and the first partition 111 is connected to the second partition 112 to define multiple chambers a. Multiple second connecting holes 115 can be formed on the second partition 112. The second connecting holes 115 can be provided for each chamber a, or some of the closed chambers a2 can be without connecting holes.

[0072] Therefore, on the one hand, the chambers a of adjacent valve cores 11 in the second direction can be connected through the second connecting hole 115 on the second partition 112, and the number of connecting parts 121 that can be integrated on a single multi-way valve 10 can be increased, and the number of components that can be used to regulate the flow of cooling medium can be increased, thereby improving the scalability and adaptability of the multi-way valve 10. On the other hand, the cooperation between the first partition 111 and the second partition 112 to define multiple chambers a can also simplify the structure of the valve core 11 and ensure the structural strength and stability of the valve core 11.

[0073] like Figure 2 and Figure 3As shown, according to some embodiments of this application, the valve core 11 further includes a third partition 113, which is disposed on the outer periphery of the second partition 112, so that at least one of the plurality of chambers a of the valve core 11 is configured as a closed chamber a2.

[0074] Specifically, the third partition 113 can be constructed as an arc-shaped plate. The third partition 113 is connected to the outer periphery of the second partition 112. For example, there is one third partition 113, and the angle corresponding to the arc length of the orthographic projection profile of the third partition 113 in the first direction is consistent with the extension angle of the orthographic projection profile of a single chamber a in the first direction, so that one of the chambers a forms a closed cavity a2. Alternatively, the angle corresponding to the arc length of the third partition 113 is consistent with the extension angle of multiple chambers a, so that multiple chambers a form a closed cavity a2. Alternatively, there are multiple third partitions 113, and the angle corresponding to the arc length of each third partition 113 is consistent with the extension angle of one or more chambers a, so that multiple chambers a form a closed cavity a2.

[0075] The third partition 113 is used only to block the chamber a radially outside the chamber a so that the chamber a forms a closed cavity a2, and when the third partition 113 is directly opposite the connecting part 121, it achieves the cut-off between the connecting part 121 and the valve core 11.

[0076] Thus, by setting the third partition 113, at least one closed cavity a2 and at least one connecting cavity a1 can be formed on each valve core 11, so that the valve core 11 can rotate relative to the valve body 12 and be opposite to different connecting parts 121, so as to realize the opening or closing of the corresponding connecting parts 121, reduce the adjustment difficulty of the multi-way valve 10, and improve the working reliability and stability.

[0077] Combination Figure 2 and Figure 3 As shown, according to some embodiments of this application, at least some adjacent chambers a are not separated by a first partition 111, or at least some of the first partition 111 are provided with a third communication hole, so that a chamber a on one valve core 11 can communicate with one or more chambers a on another valve core 11.

[0078] For example, see Figure 5 and Figure 6 As shown, where, Figure 5 and Figure 6 Only the connecting parts 112 in the first valve core 11a and the second valve core 11b that participate in external communication are shown.

[0079] Further integration Figure 9As shown, there is no first partition 111 between the first chamber 01 and the second chamber 02, between the second chamber 02 and the third chamber 03, between the third chamber 03 and the fourth chamber 04, between the fifth chamber 05 and the sixth chamber 06, and between the seventh chamber 07 and the eighth chamber 08. However, a first partition 111 is provided between the first chamber 01 and the eighth chamber 08, between the fourth chamber 04 and the fifth chamber 05, and between the sixth chamber 06 and the seventh chamber 07, so that the first chamber 01, the second chamber 02, the third chamber 03, and the fourth chamber 04 are connected, and the fifth chamber 05 and the sixth chamber 06 are connected. The seventh chamber 07 and the eighth chamber 08 are connected, and the second chamber 02, the fifth chamber 05 and the eighth chamber 08 are constructed as a closed cavity a2, so that multiple connecting parts 121 (e.g., two or three) can be connected to each other by switching positions between the first chamber 01, the third chamber 03 and the fourth chamber 04, and can be cut off by switching positions on the second chamber 02. A single connecting part 121 can be switched between the fifth chamber 05 and the sixth chamber 06 to achieve opening or closing, or can be switched between the seventh chamber 07 and the eighth chamber 08 to achieve opening or closing.

[0080] Similarly, further combining Figure 10 As shown, there is no first partition 111 between the ninth chamber 09 and the tenth chamber 010, between the eleventh chamber 011 and the twelfth chamber 012, between the twelfth chamber 012 and the thirteenth chamber 013, between the thirteenth chamber 013 and the fourteenth chamber 014, between the fifteenth chamber 015 and the sixteenth chamber 016, and between the sixteenth chamber 016 and the ninth chamber 09. There is also no first partition 111 between the tenth chamber 010 and the eleventh chamber 011, and between the fourteenth chamber 014 and the fifteenth chamber 015. A first partition 111 is provided between them, and the ninth chamber 09, the eleventh chamber 011, the thirteenth chamber 013 and the fifteenth chamber 015 are constructed as closed cavities a2, so that multiple connecting parts 121 (e.g., two or three) can be connected or disconnected from each other by switching the position between the ninth chamber 09, the tenth chamber 010, the fifteenth chamber 015 and the sixteenth chamber 016, and can be connected or disconnected from each other by switching the position between the eleventh chamber 011 and the fourteenth chamber 014.

[0081] The first valve core 11a and the second valve core 11b cooperate to allow the connecting part 121 corresponding to the first valve core 11a to connect with the connecting part 121 corresponding to the second valve core 11b. Multiple chambers a on the first valve core 11a can connect with one or more chambers a on the second valve core 11b, thereby realizing the parallel, series, and mixed connection of cooling medium circuits corresponding to multiple components connected to the multi-way valve 10. Based on the thermal management system 100, the temperature regulation of multiple components in the thermal management system 100 can be executed individually, synchronously, or in waste heat recovery mode, etc., reducing the difficulty of fine-grained control of the thermal management system 100, achieving efficient control, and improving the user experience.

[0082] Combination Figure 9 and Figure 10 As shown, according to some embodiments of this application, at least one communicating cavity a1 is provided between the closed cavities a2 on the same valve core 11.

[0083] For example, see Figure 9 and Figure 10 As shown, it should be noted that Figure 9 and Figure 10 In the diagram, adjacent chambers a without a first partition 111 are indicated by dashed lines, while those with a first partition 111 are indicated by cross-sectional lines. Similarly, closed chamber a2 is indicated by cross-sectional lines for the third partition 113. The first connecting hole 114 of connected chamber a1 is indicated by dashed lines. The second chamber 02 between the first chamber 01 and the third chamber 03, the fifth chamber 05 between the fourth chamber 04 and the sixth chamber 06, the eighth chamber 08 between the seventh chamber 07 and the first chamber 01, the ninth chamber 09 between the tenth chamber 010 and the sixteenth chamber 016, the eleventh chamber 011 between the tenth chamber 010 and the twelfth chamber 012, the thirteenth chamber 013 between the twelfth chamber 012 and the fourteenth chamber 014, and the fifteenth chamber 015 between the fourteenth chamber 014 and the sixteenth chamber 016 are all constructed as closed chambers a2.

[0084] Therefore, by providing a connecting cavity a1 between adjacent closed cavities a2, the valve core 11 can switch between opening and closing by rotating an angle, making the switching easier and the control of the multi-way valve 10 easier.

[0085] like Figure 8 As shown, Figure 8In the valve core 11 shown, the two chambers a that are opposite each other at a 180° angle are a closed chamber a2 and a connecting chamber a1, respectively. The closed chamber a2 does not have a second connecting hole 115 on the area corresponding to the second partition plate 112, and it is not connected to the chamber a on the valve core 11 adjacent in the first direction. The connecting chamber a1 has a second connecting hole 115 on the area corresponding to the second partition plate 112, and it can be connected to the adjacent valve core 11 through the second connecting hole 115. As shown in the figure, the closed chamber a2 is connected to the third partition plate 113 so that when it is opposite to any connecting part 121, the component connected to the connecting part 121 is in a closed state. The connecting chamber a1 has a first connecting hole 116 formed radially so that when it is opposite to any connecting part 121, the component connected to the connecting part 121 can be connected to the connecting chamber a1. The figure also shows the first partition plate 111, which separates the connecting chamber a1 from the chamber a adjacent to it in the counterclockwise direction.

[0086] like Figure 8 As shown, according to some embodiments of this application, the valve core 11 further includes a rotating shaft 116, at least one end of which protrudes from the valve core 11 in a first direction and is used to drive the valve core 11 to rotate in a second direction.

[0087] Therefore, the valve core 11 can be rotated by the rotating shaft 116, and the rotating shaft 116 can be further connected to the drive structure. This can also reduce the difficulty of regulating the multi-way valve 10, and realize the supply or connection of cooling medium to each connecting part 121 according to the rotation angle, so as to improve the regulation accuracy and achieve fine regulation.

[0088] It is understood that each valve core 11 includes at least one communicating cavity a1 and at least one closed cavity a2.

[0089] like Figure 1 As shown, this application provides a thermal management system 100, including: a multi-way valve 10 in the above embodiment.

[0090] For example, such as Figure 5 As shown, the multi-way valve 10 includes a first valve core 11a, a second valve core 11b, and a valve body 12. The valve body 12 is provided with a first to a sixth connecting portion. When the third chamber 03 of the first valve core 11a is connected to the first connecting portion, the fourth chamber 04 is connected to the third connecting portion, and the twelfth chamber 012 of the second valve core 11b is connected to the fifth connecting portion, the first, second, and third connecting portions can be connected, while the third, fourth, and sixth connecting portions are in a closed state. Figure 6As shown, when the fifth chamber 05 of the first valve core 11a is connected to the first connecting part and the sixth chamber 06 is connected to the second connecting part, and the fourteenth chamber 014 of the second valve core 11b is connected to the fourth connecting part and the sixteenth chamber 016 is connected to the sixth connecting part, the third connecting part and the fifth connecting part can be in a closed state, the first connecting part is connected to the fourth connecting part, and the second connecting part is connected to the sixth connecting part.

[0091] It should be noted that the multiple connecting parts 121 can be connected to the low-temperature radiator, cooling medium pump, controller, battery, condenser, cooling system and other structures of the thermal management system 100 respectively, and through the above-mentioned regulation, the components that need to be cooled are connected to the cooling system and the low-temperature radiator to achieve low-temperature cooling, and the cooling medium circuit of the components that need to be heated can be connected in series with the cooling medium circuit that needs to be cooled to achieve waste heat recovery, etc.

[0092] According to the embodiments of this application, the thermal management system 100 using the above-mentioned multi-way valve 10 can not only reduce the cost of the thermal management system 100, reduce the space occupation of the thermal management system 100, and reduce the difficulty of layout, but also realize the fine control of the thermal management system 100, reduce the control difficulty, and enable the thermal management system 100 to operate stably and efficiently.

[0093] This application provides a vehicle 1000, including: the thermal management system 100 in the above embodiment, which has the same technical effects as the thermal management system 100 described above, and will not be repeated here.

[0094] Other components and operations of the multi-way valve 10, thermal management system 100, and vehicle 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
