[0051] Figure 1 Schematic diagram of a multi-way control valve 1000 provided according to one embodiment of the present application. Figure 2 for Figure 1 Exploded view of the multi-way control valve 1000. Figure 3 for Figure 1 Schematic diagram of the cooperation between the interior of the housing 10 and the rotor valve core in the multi-way control valve 1000.

[0052] See also Figures 1 to 3 The multi-way control valve 1000 includes a housing 10 and a rotor control module 20. The housing 10 is provided with a first flow distribution chamber R1, a second flow distribution chamber R2, a transfer flow channel D3, a plurality of first flow channels D1 and a plurality of second flow channels D2. The first flow distribution chamber R1 and the second flow distribution chamber R2 are arranged horizontally at intervals and connected through the transfer flow channel D3. The plurality of first flow channels D1 are connected to the first flow distribution chamber R1, and the plurality of second flow channels D2 are connected to the second flow distribution chamber R2.

[0053] The rotor control module 20 is connected to the housing 10 and includes a first rotor valve core 21 and a second rotor valve core 22. The first rotor valve core 21 is disposed in the first flow distribution chamber R1 and is rotatable to adjust the on-off relationship between the plurality of first flow channels D1 and the transfer flow channel D3. The second rotor valve core 22 is disposed in the second flow distribution chamber R2 and is rotatable to adjust the on-off relationship between the plurality of second flow channels D2 and the transfer flow channel D3.

[0054] In this embodiment, the multi-way control valve 1000 at least includes a housing 10 and a rotor control module 20 , and the rotor control module 20 is fixedly mounted on the housing 10 .

[0055] At least two flow distribution chambers and a plurality of flow channels are formed in the housing 10. The two flow distribution chambers are respectively the first flow distribution chamber R1 and the second flow distribution chamber R2. Among the plurality of flow channels, the one connected to the first flow distribution chamber R1 is the first flow channel D1, and the one connected to the second flow distribution chamber R2 is the second flow channel D2. Among the plurality of flow channels, the one connecting the first flow distribution chamber R1 and the second flow distribution chamber R2 is the transfer flow channel D3. Among them, the number of the first flow channel D1 and the number of the second flow channel D2 are both at least two.

[0056] The rotor control module 20 has at least two rotor valve cores, which are a first rotor valve core 21 and a second rotor valve core 22 . The first rotor valve core 21 cooperates with the first flow distribution chamber R1 , and the second rotor valve core 22 cooperates with the second flow distribution chamber R2 .

[0057] The first rotor valve core 21 can rotate in the first distribution chamber R1 to control the on-off relationship of the flow channel connected to the first distribution chamber R1, and the second rotor valve core 22 can rotate in the second distribution chamber R2 to control the on-off relationship of the flow channel connected to the second distribution chamber R2.

[0058] The on-off relationship here refers to the connection or disconnection between at least two flow channels. Here, all the first flow channels D1 and the transfer flow channels D3 are connected to the first distribution chamber R1, and all the second flow channels D2 and the transfer flow channels D3 are connected to the second distribution chamber R2.

[0059] That is, the first rotor valve core 21 can switch the connection between at least two first flow channels D1 and / or the connection between the first flow channel D1 and the transit flow channel D3, and the second rotor valve core 22 can switch the connection between at least two second flow channels D2 and / or the connection between the second flow channel D2 and the transit flow channel D3.

[0060] In this way, the first rotor valve core 21 cooperates with the first distribution chamber R1 to divert the fluid passing through the first distribution chamber R1 to different flow paths, and the second rotor valve core 22 cooperates with the second distribution chamber R2 to divert the fluid passing through the second distribution chamber R2 to different flow paths.

[0061] In combination with the above, it can be known that the multi-way control valve integrates at least two valve units, which are connected through the transfer flow channel D3 and can distribute the fluid entering the housing 10 to different flow channels. In specific applications, the multi-way control valve can be arranged in a vehicle thermal management system to reduce the number of control valves, joints, and pipelines and improve integration. Of course, the number of required flow channels can be designed according to the number of required matching pipelines.

[0062] In one embodiment, the housing 10 can be formed by injection molding a plastic (such as PP material or PE material) shell and splicing with pipes, and the pipes are assembled to form the internal flow channel and distribution chamber. In another embodiment, the housing 10 is formed by machining the blank formed by injection molding to form the internal flow channel. Of course, the present application is not limited to this.

[0063] In some optional embodiments, the first rotor valve core 21 includes a first rotating shaft 211 and a first valve core 212 . The first valve core 212 is eccentrically disposed at one axial end of the first rotating shaft 211 and is located in the first flow distribution chamber R1 .

[0064] The peripheral side wall of the first valve core 212 can at least block any flow channel inlet and outlet of the transfer flow channel D3 and the plurality of first flow channels D1 formed on the peripheral side of the first flow distribution chamber R1.

[0065] In this embodiment, the first rotor valve core 21 at least includes a first rotating shaft 211 and a first valve core 212 . The first valve core 212 is located at one axial end of the first rotating shaft 211 , specifically at the axial bottom end of the first rotating shaft 211 .

[0066] The first valve core 212 is eccentrically fixed at the axial bottom end of the first rotating shaft 211, that is, the axial line of the first rotating shaft 211 does not pass through the center of the first valve core 212. In this way, the first valve core 212 is equivalent to an eccentric block located at the bottom end of the first rotating shaft 211, similar to an eccentric pendulum design, which makes rotation more convenient and reduces resistance.

[0067] In this embodiment, the peripheral side wall of the first valve core 212 can at least cover the flow channel inlet and outlet formed by a flow channel at the first flow distribution chamber R1, so as to block the corresponding flow channel. It should be understood that only the plurality of first flow channels D1 and the transfer flow channel D3 form the flow channel inlet and outlet at the peripheral side of the first flow distribution chamber R1.

[0068] In the illustrated embodiment, the cross-section of the first valve core 212 is fan-shaped, but is not limited thereto, ensuring that the peripheral side wall of the first valve core 212 can cover the flow channel inlet and outlet at the peripheral side of the first flow distribution chamber R1.

[0069] In some optional embodiments, the second rotor valve core 22 includes a second rotating shaft 221 and a second valve core 222 . The second valve core 222 is disposed at one axial end of the second rotating shaft 221 and is located in the second flow distribution chamber R2 .

[0070] The second valve core 222 is provided with a first valve core flow channel D4 and a second valve core flow channel D5 which are arranged at intervals. The first valve core flow channel D4 can connect two flow channels connected to the second distribution chamber R2, and the second valve core flow channel D5 can connect another two flow channels connected to the second distribution chamber R2.

[0071] In this embodiment, the second rotor valve core 22 at least includes a second rotating shaft 221 and a second valve core 222 . The second valve core 222 is located at one axial end of the second rotating shaft 221 , specifically at the axial bottom end of the second rotating shaft 221 .

[0072] The second valve core 222 is coaxially arranged at the axial bottom end of the second rotating shaft 221 . The second valve core 222 can rotate together with the second rotating shaft 221 . Two valve core flow channels are arranged in the second valve core 222 , namely the first valve core flow channel D4 and the second valve core flow channel D5 .

[0073] The first valve core flow channel D4 and the second valve core flow channel D5 are both two-way flow channels, which means that the flow channel has only two flow channel inlets and outlets, that is, a single valve core flow channel can only connect the two flow channel inlets and outlets at the peripheral side of the second flow distribution chamber R2 in series, that is, a single valve core flow channel can connect the two flow channels connected to the second flow distribution chamber R2. In addition, the first valve core flow channel D4 and the second valve core flow channel D5 are independent of each other, that is, the two are not connected, that is, the two are arranged at intervals.

[0074] In the illustrated embodiment, the second valve core 222 is cylindrical and is coaxially arranged with the second rotating shaft 221, and the first valve core flow channel D4 and the second valve core flow channel D5 are both arc-shaped flow channels. Of course, the present application is not limited thereto, and the shape of the second valve core 222, the number, position, and shape of the valve core flow channels can be adjusted according to design requirements.

[0075] In a further optional embodiment, the rotor control module 20 also includes a second shaft driving module 24, which is connected to the second shaft 221 and can rotate the second shaft 221 to drive the second valve core 222 to switch the positions of the first valve core flow channel D4 and the second valve core flow channel D5.

[0076] In this embodiment, the second shaft driving module 24 is used to drive the second shaft 221 to drive the second valve core 222 to rotate, thereby changing the positions of the first valve core flow channel D4 and the second valve core flow channel D5 in the second distribution chamber R2, thereby switching the flow channels connected to the second distribution chamber R2.

[0077] In one embodiment, the first rotating shaft driving module 23 and the second rotating shaft driving module 24 can both be formed by a motor and a gear transmission mechanism to form a driving functional unit capable of outputting rotational motion. The gear transmission mechanism is connected to the first rotating shaft 211 and includes a gear set, a worm gear, etc. After the speed output by the motor is decelerated by the gear transmission mechanism, the first rotating shaft 211 is in a suitable speed range. In another optional embodiment, the first rotating shaft driving module 23 and the second rotating shaft driving module 24 can both be formed by a motor and a synchronous belt to form a driving unit capable of outputting rotational motion. Of course, the present application is not limited to this.

[0078] In some optional embodiments, the rotor control module 20 further includes a controller connector 25 , and the controller connector 25 is used to introduce power and control information to control the operation of the first shaft driving module 23 and the second shaft driving module 24 .

[0079] In this embodiment, the control of the dual drive modules can be achieved through only one controller connector 25, which can reduce the number of required control signals. Of course, the number of signal harnesses can also be reduced, which is conducive to improving the degree of integration.

[0080] In a specific application, the controller connector 25 has three pins, two of which are used to connect to the positive pole and the negative pole respectively, and the other is used to connect to the control signal, which can be a pulse signal for example.

[0081] Figure 4 It is a schematic diagram showing that the first valve core 212 is in the transfer channel blocking position and the second valve core 222 is in the first position; Figure 5 It is a schematic diagram showing that the first valve core 212 is in the transfer channel blocking position and the second valve core 222 is in the second position; Figure 6 It is a schematic diagram showing that the first valve core 212 is in the transfer channel blocking position and the second valve core 222 is in the third position; Figure 7 It is a schematic diagram showing that the first valve core 212 is in the transit channel blocking position and the second valve core 222 is in the fourth position.

[0082] See also Figures 4 to 7 In a further optional embodiment, the rotor control module 20 further includes a first shaft driving module 23, which is connected to the first shaft 211 and can rotate the first shaft 211 to drive the first valve core 212 to switch positions.

[0083] The plurality of first flow channels D1 include a first flow channel D11 and a first flow channel D12 . The first flow channel D11 and the first flow channel D12 are located at two opposite sides of a line connecting the centers of the first flow distribution chamber R1 and the second flow distribution chamber R2 .

[0084] The first shaft driving module 23 is configured to drive the first valve core 212 to rotate to the transit flow channel blocking position. In the transit flow channel blocking position, the peripheral side wall of the first valve core 212 blocks the flow channel inlet and outlet of the transit flow channel D3 at the peripheral side of the first distribution chamber R1, and the first flow channel No. 1 D11 is connected to the first flow channel No. 2 D12 via the first distribution chamber R1.

[0085] In this embodiment, the first rotor valve core 21 is driven by the first shaft driving module 23 , and the first shaft 211 drives the first valve core 212 to rotate in the first flow distribution chamber R1 to change the position of the first valve core 212 in the first flow distribution chamber R1 .

[0086] In addition, in the present embodiment, the number of the first flow channels D1 is 2 and they correspond to first flow channel No. 1 D11 and first flow channel No. 2 D12 respectively. First flow channel No. 1 D11 and first flow channel No. 2 D12 are located on opposite sides of the first distribution chamber R1 and also on opposite sides of the center line connecting the first distribution chamber R1 and the second distribution chamber R2.

[0087] The first valve core 212 can rotate to the intermediate flow channel blocking position under the drive of the first shaft driving module 23. In the intermediate flow channel blocking position, the flow channel inlet and outlet of the intermediate flow channel D3 at the peripheral side of the first distribution chamber R1 is blocked by the peripheral side wall of the first valve core 212, and the first flow channel D11 No. 1 and the first flow channel D12 No. 2 are connected via the first distribution chamber R1. That is, the first distribution chamber R1 and the second distribution chamber R2 are isolated.

[0088] Figure 8 It is a schematic diagram showing that the first valve core 212 is in the blocking position of the first flow channel No. 2 and the second valve core 222 is in the first position; Fig. 9 It is a schematic diagram showing that the first valve core 212 is in the No. 2 first flow channel blocking position and the second valve core 222 is in the second position; Fig.10 It is a schematic diagram showing that the first valve core 212 is in the No. 2 first flow channel blocking position and the second valve core 222 is in the third position; Fig.11 It is a schematic diagram showing that the first valve core 212 is in the first flow channel blocking position No. 2 and the second valve core 222 is in the fourth position.

[0089] See also Figures 8 to 9 In some optional embodiments, the first shaft driving module 23 is further configured to drive the first valve core 212 to rotate to the No. 1 first flow channel blocking position or the No. 2 first flow channel blocking position.

[0090] In the blocking position of the first flow channel No. 1, the peripheral side wall of the first valve core 212 blocks the flow channel inlet and outlet of the first flow channel No. 1 D11 at the peripheral side of the first distribution chamber R1, and the first flow channel No. 2 D12 is connected to the transfer flow channel D3 via the first distribution chamber R1.

[0091] In the blocking position of the No. 2 first flow channel, the peripheral side wall of the first valve core 212 blocks the flow channel inlet and outlet of the No. 2 first flow channel D12 at the first distribution chamber R1, and the No. 1 first flow channel D11 is connected to the transfer flow channel D3 via the first distribution chamber R1.

[0092] In this embodiment, the first valve core 212 can be rotated to the No. 1 flow channel blocking position or the No. 2 first flow channel blocking position under the action of the first shaft driving module 23.

[0093] When the first valve core 212 is in the No. 1 first flow channel blocking position, the peripheral side wall of the first valve core 212 is located at the flow channel inlet and outlet of the No. 1 first flow channel D11 at the peripheral side of the first flow distribution chamber R1, so as to block the flow channel inlet and outlet of the No. 1 first flow channel D11 at the peripheral side of the first flow distribution chamber R1. At this time, the No. 1 first flow channel D11 cannot flow fluid, and the No. 2 first flow channel D12 is connected to the transfer flow channel D3.

[0094] When the first valve core 212 is in the blocking position of the first flow channel No. 2, the peripheral side wall of the first valve core 212 is located at the flow channel inlet and outlet of the first flow channel No. 2 at the peripheral side of the first flow distribution chamber R1, so as to block the flow channel inlet and outlet of the first flow channel No. 2 at the peripheral side of the first flow distribution chamber R1. At this time, the first flow channel No. 2 D12 cannot flow fluid, and the first flow channel No. 1 D11 is connected to the transfer flow channel D3.

[0095] exist Figures 8 to 11 In the illustrated embodiment, the first valve core 212 is in the first flow channel blocking position No. 2. It can be understood that the first valve core 212 only needs to be rotated 180° to switch to the first flow channel blocking position No. 1.

[0096] Fig.12 It is a schematic diagram showing that the first valve core 212 is in a proportional adjustment position and the second valve core 222 is in a first position; Fig.13 It is a schematic diagram showing that the first valve core 212 is in the same proportional adjustment position and the second valve core 222 is in the second position; Fig.14 It is a schematic diagram showing that the first valve core 212 is in the same proportional adjustment position and the second valve core 222 is in the third position; Fig.15 It is a schematic diagram showing that the first valve core 212 is in the same proportional adjustment position and the second valve core 222 is in the fourth position.

[0097] See also Figures 12 to 15 In some optional embodiments, the first shaft driving module 23 is further configured to drive the first valve core 212 to rotate to a proportional adjustment position.

[0098] In the proportional adjustment position, the No. 1 first flow channel D11 , the No. 2 first flow channel D12 , and the transfer flow channel D3 are connected via the first flow distribution chamber R1 .

[0099] In this embodiment, when the first valve core 212 is in the proportional adjustment position, the peripheral side wall of the first valve core 212 does not block any flow channel inlet or outlet formed by the first flow channel No. 1 D11, the first flow channel No. 2 D12 and the transfer flow channel D3 on the peripheral side of the first distribution chamber R1.

[0100] In this embodiment, the coverage range of the circumferential side wall of the first valve core 212 is only allowed to completely block at most one flow channel inlet and outlet at the circumferential side of the first distribution chamber R1, that is, more than two flow channel inlets and outlets cannot be blocked at the same time. In an optional embodiment, when the first valve core 212 is in the proportional adjustment position, the circumferential side wall of the first valve core 212 blocks part of one flow channel inlet and outlet at the circumferential side of the first distribution chamber R1. In another optional embodiment, when the first valve core 212 is in the proportional adjustment position, the circumferential side wall of the first valve core 212 blocks part of two flow channel inlets and outlets at the circumferential side of the first distribution chamber R1. In another optional embodiment, the circumferential side wall of the first valve core 212 does not completely block any opening at the circumferential side of the first distribution chamber R1.

[0101] In this way, the No. 1 first flow channel D11 , the No. 2 first flow channel D12 , and the transfer flow channel D3 can all be interconnected through the first flow distribution chamber R1 .

[0102] See also Figures 12 to 15 , Fig.12 and Fig.15 The side wall of the first valve core 212 blocks the two flow channel inlets and outlets at the side of the first flow distribution chamber R1. In the illustrated embodiment, the side wall of the first valve core 212 blocks the flow channel inlet and outlet of the transfer flow channel D3 at the side of the first flow distribution chamber R1, and the flow channel inlet and outlet of the No. 2 first flow channel D12 at the side of the first flow distribution chamber R1.

[0103] Exemplarily, the fluid enters the first distribution chamber R1 from the first flow channel No. 1 D11 and then can be split into the transfer flow channel D3 and the first flow channel No. 2 D12 to achieve proportional splitting.

[0104] Understandably, in Fig.12 and Fig.15 On this basis, the first valve core 212 is rotated clockwise by about 90°, and the peripheral side wall of the first valve core 212 blocks the part of the flow inlet and outlet of the first flow channel D11 No. 1 at the peripheral side of the first distribution chamber R1, and the part of the flow inlet and outlet of the transit flow channel D3 at the peripheral side of the first distribution chamber R1.

[0105] Fig.16 It is a schematic diagram showing that the first valve core 212 is in another proportional adjustment position and the second valve core 222 is in the first position. Fig.16 The diagram shows a portion of the peripheral side wall of the first valve core 212 that blocks an inlet and outlet of a flow passage at the peripheral side of the first flow distribution chamber R1.

[0106] In the illustrated embodiment, the peripheral side wall of the first valve core 212 blocks part of the flow inlet and outlet of the first flow channel D12 No. 2 at the peripheral side of the first distribution chamber R1, the flow inlet and outlet of the transit flow channel D3 at the peripheral side of the first distribution chamber R1 are completely open, and the flow inlet and outlet of the first flow channel D11 No. 1 at the peripheral side of the first distribution chamber R1 are completely open.

[0107] Exemplarily, the fluid enters the first distribution chamber R1 from the first flow channel No. 1 D11, and then can be diverted into the transfer flow channel D3 and the first flow channel No. 2 D12. Since the flow channel inlet and outlet of the transfer flow channel D3 at the peripheral side of the first distribution chamber R1 are completely open, the fluid flow entering the transfer flow channel D3 exceeds the fluid flow entering the first flow channel No. 2 D12, thereby achieving proportional diversion.

[0108] Understandably, in Fig.16 On the basis of the illustrated embodiment, the first valve core 212 is rotated counterclockwise by about 45° (the first valve core 212 is in a relative position to the transit flow channel D3), so that the first valve core 212 does not block any opening formed on the peripheral side of the first distribution chamber R1, that is, the flow inlet and outlet of the transit flow channel D3 on the peripheral side of the first distribution chamber R1 are fully opened, the flow inlet and outlet of the No. 1 first flow channel D11 on the peripheral side of the first distribution chamber R1 are fully opened, and the flow inlet and outlet of the No. 2 first flow channel D12 on the peripheral side of the first distribution chamber R1 are fully opened.

[0109] In some optional embodiments, the second shaft driving module 24 is configured to drive the second valve core 222 to rotate the first valve core flow channel D4 and the second valve core flow channel D5 to any one of the first position, the second position, the third position and the fourth position.

[0110] In the first position, the first valve core flow channel D4 connects the transfer flow channel D3 and the second flow channel No. 2 D22 , and the second valve core flow channel D5 connects the second flow channel No. 3 D23 and the second flow channel No. 4 D24 .

[0111] In the second position, the first valve core flow channel D4 connects the transfer flow channel D3 and the No. 1 second flow channel D21 , and the second valve core flow channel D5 connects the No. 3 second flow channel D23 and the No. 4 second flow channel D24 .

[0112] In the third position, the first valve core flow channel D4 connects the No. 2 second flow channel D22 with the No. 3 second flow channel D23, and the second valve core flow channel D5 connects the transfer flow channel D3 with the No. 4 second flow channel D24.

[0113] In the fourth position, the first valve core flow channel D4 connects the No. 1 second flow channel D21 with the No. 3 second flow channel D23 , and the second valve core flow channel D5 connects the transfer flow channel D3 with the No. 4 second flow channel D24 .

[0114] In this embodiment, the second valve core 222, driven by the second shaft driving module 24, can rotate the first valve core flow channel D4 and the second valve core flow channel D5 to any one of at least four positions, which are the first position, the second position, the third position and the fourth position.

[0115] Figures 4 to 7 Schematic diagrams showing the second valve core 222 in four positions are shown respectively. Figures 8 to 11 Schematic diagrams showing the second valve core 222 in four positions are also shown. Figures 12 to 15 Schematic diagrams showing the second valve core 222 in four positions are also shown.

[0116] See also Figure 4 ,or Figure 8 ,or Fig.12 When the second valve core 222 is in the first position, the transfer channel D3 and the second channel D22 No. 2 are connected through the first valve core channel D4, and the second channel D23 No. 3 and the second channel D24 No. 4 are connected through the second valve core channel D5.

[0117] See also Figure 5 ,or Fig. 9 ,or Fig.13 When the second valve core 222 is in the second position, the transfer channel D3 is connected to the No. 1 second channel D21 through the first valve core channel D4, and the No. 3 second channel D23 is connected to the No. 4 second channel D24 through the second valve core channel D5.

[0118] See also Figure 6 ,or Fig.10 ,or Fig.14 When the second valve core 222 is in the third position, the second flow channel No. 2 D22 is connected to the second flow channel No. 3 D23 through the first valve core flow channel D4, and the transfer flow channel D3 and the second flow channel No. 4 D24 are connected through the second valve core flow channel D5.

[0119] See also Figure 7 ,or Fig.11 ,or Fig.15 When the second valve core 222 is in the fourth position, the No. 1 second flow channel D21 is connected to the No. 3 second flow channel D23 through the first valve core flow channel D4, and the transfer flow channel D3 and the No. 4 second flow channel D24 are connected through the second valve core flow channel D5.

[0120] Combination Figures 4 to 16 These drawings show the combination of the position of the first valve core 212 in the first distribution chamber R1 and the position of the second valve core 222 in the second distribution chamber R2. Of course, the combination formed by the two is not limited to these drawings and will not be illustrated one by one here.

[0121] See also Fig.16 In the illustrated embodiment, the transfer flow channel D3 is a four-way flow channel, wherein two flow channel inlets and outlets are respectively located on the peripheral sides of the first distribution chamber R1 and the second distribution chamber R2, and the other two flow channel inlets and outlets are located at the bottom of the shell 10 and correspond to the first flow channel inlet and outlet C1 and the fourth flow channel inlet and outlet C4.

[0122] The first flow channel No. 1 D11 and the first flow channel No. 2 D12 are both two-way flow channels, one of the flow channel inlets and outlets are located on the peripheral side of the first distribution chamber R1, and the other flow channel inlets and outlets are located at the bottom of the shell 10 and correspond to the second flow channel inlet and outlet C2 and the third flow channel inlet and outlet C3.

[0123] Second flow channel No. 1 D21, second flow channel No. 2 D22 and second flow channel No. 4 D24 are all two-way flow channels, one of the flow channel inlets and outlets of the three are located on the peripheral side of the second distribution chamber R2, and the other flow channel inlets and outlets of the three are located at the bottom of the shell 10 and correspond to the ninth flow channel inlet and outlet C9, the eighth flow channel inlet and outlet C8 and the fifth flow channel inlet and outlet C5.

[0124] The No. 3 second flow channel D23 is a three-way flow channel, one of which is located at the peripheral side of the second flow distribution chamber R2, and the other two are located at the bottom of the shell 10 and correspond to the sixth flow channel inlet and outlet C6 and the seventh flow channel inlet and outlet C7.

[0125] In combination with the above, it can be known that the first valve core 212 cooperates with the first distribution chamber R1 to mainly control the second flow channel inlet and outlet C2 and the third flow channel inlet and outlet C3, and the second valve core 222 cooperates with the second distribution chamber R2 to mainly control the first flow channel inlet and outlet C1, the fourth flow channel inlet and outlet C4, the fifth flow channel inlet and outlet C5, the sixth flow channel inlet and outlet C6, the seventh flow channel inlet and outlet C7, the eighth flow channel inlet and outlet C8 and the ninth flow channel inlet and outlet C9. That is, a nine-way control valve with a dual-drive valve core is provided, and of course the number of valve cores, distribution chambers and flow channels can be appropriately increased or decreased to adapt to different design requirements.

[0126] In another aspect of the present application, a vehicle is provided. The vehicle includes a vehicle thermal management system. The vehicle thermal management system includes the multi-way control valve 1000 described above.

[0127] In other words, the multi-way control valve 1000 can be applied to a vehicle thermal management system. Taking the nine-way control valve of the dual-drive valve core shown in the figure as an example, the nine-way control valve can be matched with an external water plate, and the external water plate is provided with interfaces that match the inlet and outlet of each flow channel to achieve flow diversion.

[0128] This can reduce the number of common three-way control valves and four-way control valves used, thereby reducing the number of required control signals, the number of pipelines, and the number of joints, etc., which can greatly improve the integration of the vehicle thermal management system, reduce the space occupied by the vehicle thermal management system, and reduce costs. Of course, the vehicle thermal management system also has other advantages brought by the multi-way control valve 1000, which will not be repeated here.

[0129] It should be noted that the above-mentioned "clockwise" and "counterclockwise" directions can be determined based on the distribution chamber in the accompanying drawings.

Features defined as "first" or "second" may explicitly or implicitly include at least one of the defined features.

Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
