[0002] New energy vehicle thermal management systems typically feature complex circuits to accommodate various heat pump modes. Multi-way water valves can be used to switch between different connectivity relationships based on system requirements.

[0045] Complex circuits are usually designed in the thermal management system of new energy vehicles to meet different heat pump modes. The use of multi-way water valves can switch different connectivity relationships according to system requirements. Since new energy vehicles need to simultaneously control the motor, battery and passenger compartment during use, the motor, battery and passenger compartment often have different cooling or heating requirements at the same time, and different connectivity relationships need to be switched from time to time. Therefore, there are often multiple multi-way valves in the system architecture, which requires the matching design of different multi-way valve molds, resulting in an increase in the cost of multi-way valve preparation and the overall cost of the vehicle.

[0046] The valve core of a single multi-way valve is provided with several connecting surfaces, each of which is provided with a connecting groove. By rotating the valve core, the connecting grooves of each connecting surface are connected to the valve port of the valve seat, so that the multi-way valve can form different conduction modes. Therefore, the number of conduction modes that a multi-way valve can form does not exceed the number of connecting surfaces. However, since the connection relationships that a single multi-way valve can form are limited, a single multi-way valve cannot cover the various different connection relationship requirements in a system. Therefore, it is necessary to design multi-way valves with different connection relationships, which in turn requires the production of molds for different multi-way valves, which increases the production cost of the multi-way valve and the vehicle.

[0047] Based on the above problems, the embodiments of the present application provide a multi-way valve, a thermal management system and a vehicle. The multi-way valve includes a valve core and a valve seat. The valve seat is arranged around the valve core. The valve core includes a plurality of connecting surfaces arranged around the valve core in a circumferential direction. At least two connecting surfaces are provided with connecting grooves. The valve seat includes n*m valve ports arranged in an array along the circumferential and axial directions of the valve core, where n≥2 and m>2. The valve core is rotatable relative to the valve seat so that the connecting groove can be connected to at least two valve ports. That is, through the rotation of the valve core, the medium can be input and output between different valve ports through the connecting grooves of different connecting surfaces to form different connecting relationships; the connecting surfaces include a first connecting surface and a second connecting surface adjacently arranged along the circumferential direction of the valve core. When the connecting groove of the first connecting surface is connected to the valve port, the multi-way valve is in the first conduction mode; when the connecting groove of the second connecting surface is connected to the valve port, the multi-way valve is in the second conduction mode; and when at least one connecting groove of the first connecting surface and at least one connecting groove of the second connecting surface are connected to the valve port, the multi-way valve can be in the third conduction mode. Therefore, in the embodiment of the present application, the two connecting surfaces of the valve core and the valve port can cooperate to form three conduction modes, so that the multi-way valve can obtain more conduction modes than the number of connecting surfaces of the valve core, so that the multi-way valve can be applied to more scenarios, and through the multi-way valve, multiple multi-way valves with different structures can be integrated to reduce the number of molds and save the preparation cost of the multi-way valve and the vehicle.

[0048] A multi-way valve, a thermal management system, and a vehicle according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0049] See also Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic structural diagram of a multi-way valve provided by an embodiment of the present application; Figure 2 is a schematic structural diagram of a valve core of a multi-way valve provided in some embodiments of the present application; Figure 3 Schematic diagram of three conduction modes of a multi-way valve provided in some embodiments of the present application.

[0050] First, as Figures 1 to 3 As shown, the present application provides a multi-way valve 1, which includes a valve core 2 and a valve seat 3. The valve core 2 includes a plurality of connecting surfaces 21 arranged around the circumference thereof, and at least two adjacent connecting surfaces 21 are provided with a connecting groove 22; the valve seat 3 is arranged around the valve core 2, and the valve seat 3 includes n*m valve ports 31 arranged in an array along the circumference and axial directions of the valve core 2, where n≥2 and m>2. The valve core 2 is rotatable relative to the valve seat 3 so that at least two valve ports 31 can be connected through a connecting groove 22.

[0051] Among them, the connecting surface 21 includes a first connecting surface 211 and a second connecting surface 212 adjacently arranged along the circumferential direction of the valve core 2, and the multi-way valve 1 is configured to include a first conducting mode, a second conducting mode and a third conducting mode. The multi-way valve 1 is in the first conducting mode, and the connecting groove 22 of the first connecting surface 211 is connected to the valve port 31; the multi-way valve 1 is in the second conducting mode, and the connecting groove 22 of the second connecting surface 212 is connected to the valve port 31; the multi-way valve 1 is in the third conducting mode, and at least one connecting groove 22 of the first connecting surface 211 and at least one connecting groove 22 of the second connecting surface 212 are connected to the valve port 31.

[0052] In the embodiment of the present application, the multi-way valve 1 includes a valve core 2 and a valve seat 3. The valve seat 3 is arranged around the valve core 2. The valve core 2 includes a plurality of connecting surfaces 21 arranged around it in a circumferential direction. At least two adjacent connecting surfaces 21 are provided with connecting grooves 22. The valve seat 3 includes n*m valve ports 31 arranged in an array along the circumferential and axial directions of the valve core 2, where n≥2 and m>2. The valve core 2 is rotatable relative to the valve seat 3 so that at least two valve ports 31 can be connected through a connecting groove 22. That is, through the rotation of the valve core 2, the medium can be input and output between different valve ports 31 through the connecting grooves 22 of different connecting surfaces to form different connecting relationships; the connecting surface 21 includes a first connecting surface 211 and a second connecting surface 212 adjacently arranged along the circumferential direction of the valve core 2. When the first connecting surface 211 is When the communicating groove 22 and the valve port 31 are connected, the multi-way valve 1 is in the first conducting mode; when the communicating groove 22 of the second communicating surface 212 and the valve port 31 are connected, the multi-way valve 1 is in the second conducting mode; and when at least one communicating groove 22 of the first communicating surface 211 and at least one communicating groove 22 of the second communicating surface 212 and the valve port 31 are connected, the multi-way valve 1 can be in the third conducting mode. Therefore, in the scheme of the embodiment of the present application, the two communicating surfaces 21 of the valve core 2 and the valve port 31 can cooperate to form three conducting modes, so that the multi-way valve 1 can obtain more conducting modes than the communicating surfaces 21 of the valve core 2, so that the multi-way valve 1 can be applied to more scenarios, and through the multi-way valve 1, multiple multi-way valves 1 with different structures can be integrated to reduce the number of molds and save the preparation cost of the multi-way valve 1 and the vehicle.

[0053] The multi-way valve 1 includes a valve core 2 and a valve seat 3. A plurality of valve ports 31 are formed through one side surface of the valve seat 3. The valve seat 3 is disposed around the valve core 2, and the valve core 2 is rotatable relative to the valve seat 3. The valve core 2 includes a plurality of communication surfaces 21 spaced apart along its circumference. Each communication surface 21 is provided with a communication groove 22. Relative rotation of the valve core 2 and the valve seat 3 allows different communication grooves 22 to communicate with the valve ports 31, thereby enabling the multi-way valve 1 to achieve different conduction modes. Exemplarily, the valve seat 3 includes two, three, four, or five communication surfaces 21. Exemplarily, one, two, or three communication grooves 22 are provided on the communication surface 21. Exemplarily, a single communication groove 22 can connect to two, three, or four valve ports 31.

[0054] Optionally, the communication groove 22 extends along the axial direction of the valve core 2; or the communication groove 22 extends along the circumferential direction of the valve core 2; or the communication groove 22 extends obliquely, so that the communication groove 22 can communicate with several valve ports 31 arranged diagonally.

[0055] That is, in the system, each valve port 31 is connected to a different pipeline respectively, and the valve core 2 is rotated to connect the communication groove 22 with different valve ports 31, so that the connection relationship of each pipeline in the system is changed.

[0056] The valve seat 3 is provided with n*m valve ports 31 along the circumferential and axial directions of the valve core 2, where n ≥ 2 and m > 2. For example, the valve seat 3 is provided with 2*3 valve ports 31, or 2*5 valve ports 31, or 3*4 valve ports 31, or 4*5 valve ports 31, etc.

[0057] The connecting surface 21 includes a first connecting surface 211 and a second connecting surface 212 adjacently arranged along the circumferential direction of the valve core 2. When the connecting groove 22 of the first connecting surface 211 is connected to the valve port 31, as shown in the attached figure, Figure 3 As shown in (a), the multi-way valve 1 is in the first conduction mode; when the valve core 2 rotates, the communication groove 22 of the second communication surface 212 and the valve port 31 are correspondingly connected, as shown in the attached Figure 3 (b) shows that the multi-way valve 1 is in the second conduction mode. The multi-way valve 1 of the embodiment of the present application also includes a third conduction mode. When the multi-way valve 1 is in the third conduction mode, part of the communication groove 22 of the first communication surface 211 and part of the communication groove 22 of the second communication surface 212 are respectively connected to the valve port 31, as shown in the attached figure. Figure 3 As shown in (c), the multi-way valve 1 thus obtains more conduction modes than the number of its connecting surfaces 21. Figure 3 The first communicating groove 221 numbered 221 is a type of the communicating groove 22 in this solution.

[0058] For example, in the prior art, two multi-way valves 1 are provided in the thermal management system, and the multi-way valve 1 includes four connecting surfaces 21, wherein one multi-way valve 1 can form a first connecting relationship, a second connecting relationship, a third connecting relationship, and a fourth connecting relationship, and the other multi-way valve 1 can form a first connecting relationship, a second connecting relationship, a third connecting relationship, and a fifth connecting relationship, so that the overall structures of the two multi-way valves 1 are different. Therefore, the two multi-way valves 1 require two different molds, and since the two multi-way valves 1 are highly similar, it is easy to cause mixing problems during assembly, and the assembly reliability is low. In the embodiment of the present application, the four connecting surfaces 21 of the multi-way valve 1 can form a first connecting relationship, a second connecting relationship, a third connecting relationship, and a fourth connecting relationship, and the multi-way valve 1 can form a fifth connecting relationship in its third conduction mode, so that this multi-way valve 1 can be used to replace the two multi-way valves 1 with different structures mentioned above, so that only one mold is required and there will be no problem of mixing of materials on the production line.

[0059] When the multi-way valve 1 is in the third conduction mode, each communication groove 22 can fully cooperate with the valve ports 31. Specifically, when a communication groove 22 is connected to n1 valve ports 31 in the first conduction mode or the second conduction mode, the communication groove 22 can still be connected to n1 valve ports 31 in the third conduction mode.

[0060] Optionally, when the multi-way valve 1 is in the third conduction mode, it can still include multiple different conduction modes. For example, when the valve core 2 rotates by an angle θ, the multi-way valve 1 switches from the first conduction mode to the second conduction mode, and the valve seat 3 includes 3*m valve ports 31. The first connecting surface 211 and the second connecting surface 212 each include three connecting grooves 22 extending along the axial direction of the valve core 2 and arranged along the circumferential direction. When the valve core 2 rotates by θ1, θ1<θ, and at this time, the two connecting grooves 22 of the first connecting surface 211 and the one connecting groove 22 of the second connecting surface 212 are connected to the valve port 31; when the valve core 2 rotates by θ2, θ1<θ2<θ, and at this time, the one connecting groove 22 of the first connecting surface 211 and the two connecting grooves 22 of the second connecting surface 212 are connected to the valve port 31.

[0061] For example, in the prior art, a multi-way valve 1 requires four connecting surfaces 21 to match four different connection relationships, while the multi-way valve 1 in the embodiment of the present application can be designed with three connecting surfaces 21 and satisfy the four connection relationships through the new connection relationship formed in the third conduction mode. In this way, the size of the multi-way valve 1 can be designed to be smaller, thereby reducing the rotational torque of the valve core 2.

[0062] In some embodiments, as Figures 1 to 3As shown, the valve seat 3 includes 2*m valve ports 31 arranged in an array along the circumferential and axial directions of the valve core 2, m>2, the communicating groove 22 includes a first communicating groove 221 extending along the axial direction of the valve core 2, the first communicating groove 221 can communicate with at least two valve ports 31 in the axial direction of the valve core 2, the first communicating surface 211 and the second communicating surface 212 are both provided with a first communicating groove 221, in the circumferential direction of the valve core 2, at least one first communicating groove 221 of the first communicating surface 211 and at least one first communicating groove 221 of the second communicating surface 212 are adjacently arranged, the multi-way valve 1 is in the third conduction mode, the valve port 31 is communicated with the two first communicating grooves 221 belonging to the first communicating surface 211 and the second communicating surface 212 and arranged adjacently.

[0063] In these embodiments, the valve seat 3 includes 2*m valve ports 31 arranged in an array along the circumferential and axial directions of the valve core 2, m>2, and the first connecting surface 211 and the second connecting surface 212 are both provided with a first connecting groove 221. In the circumferential direction of the valve core 2, at least one first connecting groove 221 of the first connecting surface 211 and at least one first connecting groove 221 of the second connecting surface 212 are adjacently arranged. The first connecting groove 221 can connect at least two valve ports 31 in the axial direction of the valve core 2. When the valve port 31 and the two first connecting grooves 221 belonging to the first connecting surface 211 and the second connecting surface 212 and arranged adjacently are connected, the multi-way valve 1 is in the third conduction mode, so that the multi-way valve 1 can be set with a larger number of conduction modes, so that the multi-way valve 1 can be applied to more scenarios, and the multi-way valve 1 can be integrated with multiple multi-way valves 1 with different structures to reduce the number of molds and save the preparation cost of the multi-way valve 1 and the vehicle.

[0064] The valve seat 3 includes 2*m valve ports 31 , where m>2. Exemplarily, the valve seat 3 includes 2*3 valve ports 31 , or the valve seat 3 includes 2*4 valve ports 31 , or the valve seat 3 includes 2*5 valve ports 31 .

[0065] The communication groove 22 includes a first communication groove 221 extending along the axial direction of the valve core 2 and capable of communicating with at least two valve ports 31. For example, the first communication groove 221 can communicate with two, three, or four valve ports 31.

[0066] The first connecting surface 211 can be provided with one first connecting groove 221 or two first connecting grooves 221 arranged side by side along the circumferential direction, and the same applies to the second connecting surface 212. When the first connecting surface 211 is provided with two first connecting grooves 221, the two first connecting grooves 221 can have the same or different axial dimensions. The same applies to the second connecting surface 212.

[0067] Each of the first and second connecting surfaces 211, 212 is provided with a first connecting groove 221. These two first connecting grooves 221 are adjacently arranged in the circumferential direction of the valve core 2. As the valve core 2 rotates, the two adjacent first connecting grooves 221 can simultaneously connect with the valve port 31, and the multi-way valve 1 is now in the third conducting mode. In other words, when the multi-way valve 1 is in the third conducting mode, the valve port 31 can connect with the two adjacent first connecting grooves 221, one on the first and second connecting surfaces 211, 212.

[0068] Optionally, the first connecting surface 211 includes two half-areas arranged opposite to each other along the circumference of the valve core 2, and the two half-areas have the same size in the circumferential direction of the valve core 2, then a first connecting groove 221 is provided on one of the two half-areas close to the second connecting surface 212; the second connecting surface 212 includes two half-areas arranged opposite to each other along the circumference of the valve core 2, and the two half-areas have the same size in the circumferential direction of the valve core 2, then a first connecting groove 221 is provided on one of the two half-areas close to the first connecting surface 211.

[0069] “When the multi-way valve 1 is in the third conduction mode, the valve port 31 is in communication with two adjacent first communicating grooves 221 that belong to the first communicating surface 211 and the second communicating surface 212 ” means that if the first communicating surface 211 and the second communicating surface 212 include four first communicating grooves 221 arranged along the circumference of the valve core 2, when the multi-way valve 1 is in the third conduction mode, the two middle first communicating grooves 221 are in communication with the valve port 31;

[0070] If the first connecting surface 211 includes a first connecting groove 221 and the second connecting surface 212 includes two first connecting grooves 221 arranged circumferentially, when the multi-way valve 1 is in the third conduction mode, the first connecting groove 221 of the first connecting surface 211 and the first connecting groove 221 on the second connecting surface 212 close to the first connecting surface 211 are connected to the valve port 31;

[0071] If the second communicating surface 212 includes a first communicating groove 221 and the first communicating surface 211 includes two first communicating grooves 221 arranged circumferentially, when the multi-way valve 1 is in the third conduction mode, the first communicating groove 221 of the second communicating surface 212 and the first communicating groove 221 on the first communicating surface 211 close to the second communicating surface 212 are in communication with the valve port 31;

[0072] If the first communicating surface 211 and the second communicating surface 212 each include a first communicating groove 221 , when the multi-way valve 1 is in the third conducting mode, the first communicating groove 221 of the first communicating surface 211 and the first communicating groove 221 of the second communicating surface 212 are in communication with the valve port 31 .

[0073] See also Figure 4 , Figure 4This is a schematic diagram of the valve core of the multi-way valve provided in some embodiments of the present application.

[0074] In some embodiments, as Figure 1 and Figure 4 As shown, the connecting groove 22 also includes a second connecting groove 222 extending along the circumferential direction of the valve core 2. The second connecting groove 222 can connect at least two valve ports 31 in the circumferential direction of the valve core 2. In at least one of the first connecting surface 211 and the second connecting surface 212, the first connecting groove 221 and the second connecting groove 222 are axially arranged.

[0075] In these embodiments, the connecting groove 22 also includes a second connecting groove 222 extending along the circumferential direction of the valve core 2. Through the combination of the first connecting groove 221 and the second connecting groove 222, the multi-way valve 1 can form more connecting relationships to adapt to more usage scenarios.

[0076] Taking the first connecting surface 211 as an example, a first connecting groove 221 and a second connecting groove 222 can be provided on the first connecting surface 211. The second connecting groove 222 can be provided at either end of the first connecting groove 221 in the axial direction. Figure 4 (a) and Figure 4 (b) as shown; or two first communicating grooves 221 and one second communicating groove 222 may be provided on the first communicating surface 211, and the second communicating groove 222 may be provided at either end of the first communicating groove 221 in the axial direction, as shown Figure 4 (c) The second communication surface 212 is similar and will not be described in detail.

[0078] In some embodiments, as Figure 1 、 Figures 5 to 7As shown, the valve seat 3 includes two valve port groups 31 arranged along the circumferential direction of the valve core 2, and the valve port group 31 includes a first valve port 311, a second valve port 312 and a third valve port 313 arranged along the axial direction of the valve core 2, wherein the first connecting groove 221 includes a first sub-connecting groove 2211 connecting the first valve port 311 and the second valve port 312 and a second sub-connecting groove 2212 connecting the second valve port 312 and the third valve port 313. When the multi-way valve 1 is in the third connecting mode, the valve seat 3 includes two valve port groups 311, a second valve port 312 and a third valve port 313. The two first sub-connecting grooves 2211 of the first connecting surface 211 and the second connecting surface 212 are connected to the valve port 31, or the two second sub-connecting grooves 2212 respectively provided on the first connecting surface 211 and the second connecting surface 212 are connected to the valve port 31, or the first sub-connecting groove 2211 located on one of the first connecting surface 211 and the second connecting surface 212 and the second sub-connecting groove 2212 located on the other of the first connecting surface 211 and the second connecting surface 212 are connected to the valve port 31.

[0079] In these embodiments, the valve seat 3 includes two valve port 31 groups arranged along the circumferential direction of the valve core 2, the valve port 31 groups include a first valve port 311, a second valve port 312 and a third valve port 313 arranged along the axial direction of the valve core 2, the first connecting groove 221 includes a first sub-connecting groove 2211 connecting the first valve port 311 and the second valve port 312, and a second sub-connecting groove 2212 connecting the second valve port 312 and the third valve port 313. Through different combinations of the first sub-connecting groove 2211 and the second sub-connecting groove 2212 and the first connecting surface 211 and the second connecting surface 212, the multi-way valve 1 can form different conduction states in the third conduction mode, so that the multi-way valve 1 can meet a variety of different application scenarios.

[0080] The valve seat 3 includes 2x3 valve ports 31. The first communicating groove 221 includes a first sub-communicating groove 2211 connecting the first valve port 311 and the second valve port 312, and a second sub-communicating groove 2212 connecting the second valve port 312 and the third valve port 313. By combining the first sub-communicating grooves 2211 and the second sub-communicating grooves 2212, four different first communicating surfaces 211 or second communicating surfaces 212 can be formed.

[0081] The valve seat 3 includes 2*3 valve ports 31, and the first connecting groove 221 includes a first sub-connecting groove 2211 connecting the first valve port 311 and the second valve port 312 and a second sub-connecting groove 2212 connecting the second valve port 312 and the third valve port 313. Figure 4 and Figure 5 As shown, by combining the first sub-communication grooves 2211 and the second sub-communication grooves 2212 , eight different first communication surfaces 211 or second communication surfaces 212 can be formed.

[0082] Therefore, the first connecting surface 211 and the second connecting surface 212 each have 8 different structures, and the first connecting surface 211 and the second connecting surface 212 have 64 combinations, such as Figure 6 shown.

[0083] There are 8 different second interconnecting surfaces 212 in the horizontal row and 8 different first interconnecting surfaces 211 in the vertical row. Figure 6 As shown, the shaded portion represents the first communicating groove 221. Any one of the 64 combinations is an expanded view of the valve core 2 at the first communicating surface 211 and the second communicating surface 212.

[0084] like Figure 7 As shown, each expanded diagram includes four columns of tables. When the first communicating grooves 221 and / or the second communicating grooves 222 in the first column and the second column from left to right in these four columns are connected to the valve port 31, the multi-way valve 1 is in the first conduction mode; when the first communicating grooves 221 and / or the second communicating grooves 222 in the second column and the third column from left to right in these four columns are connected to the valve port 31, the multi-way valve 1 is in the third conduction mode; when the first communicating grooves 221 and / or the second communicating grooves 222 in the third column and the fourth column from left to right in these four columns are connected to the valve port 31, the multi-way valve 1 is in the second conduction mode.

[0085] In some embodiments, as Figure 1 、 Figure 6 and Figure 7 As shown, the first connecting surface 211 and the second connecting surface 212 include four first connecting grooves 221 arranged along the circumference of the valve core 2, the valve core 2 includes a top end 23 in its axial direction, and the first connecting groove 221 includes two first ends 231 and a second end 232 arranged opposite to each other in the axial direction of the valve core 2. The spacing between the first end 231 and the top end 23 of at least one first connecting groove 221 is different from the spacing between the first end 231 and the top end 23 of at least two other first connecting grooves 221, or the spacing between the second end 232 and the top end 23 of at least one first connecting groove 221 is different from the spacing between the second end 232 and the top end 23 of at least two other first connecting grooves 221; or, one of the first connecting surface 211 and the second connecting surface 212 is provided with a second connecting groove 222.

[0086] In these embodiments, by adjusting the positions of the four first communicating grooves 221 arranged along the circumference of the valve core 2 on the first communicating surface 211 and the second communicating surface 212, by making the distance between the first end 231 and the top end 23 of at least one first communicating groove 221 different from the distance between the first end 231 and the top end 23 of at least two other first communicating grooves 221, or by making the distance between the second end 232 and the top end 23 of at least one first communicating groove 221 different from the distance between the second end 232 and the top end 23 of at least two other first communicating grooves 221, or by providing the second communicating groove 222 on one of the first communicating surface 211 and the second communicating surface 212, as the valve core 2 rotates, at least two adjacent conduction modes of the multi-way valve 1 differ, such as the difference between the first conduction mode and the second conduction mode or the difference between the second conduction mode and the third conduction mode, thereby reducing the rotation distance of the valve core 2 when the multi-way valve 1 changes the conduction mode, thereby improving the transition and response rate of the multi-way valve 1.

[0087] When the valve seat 3 includes 2*m valve ports 31, the first connecting surface 211 and the second connecting surface 212 include four rows of first connecting grooves 221 arranged along the circumference of the valve core 2. In the first and third conducting modes of the multi-way valve 1, or in the third and second conducting modes of the multi-way valve 1, three different first connecting grooves 221 communicate with the valve ports 31. Therefore, if one of these three first connecting grooves 221 extends differently from the other two connecting grooves 22, or connects to different valve ports 31, as the valve core 2 rotates, the multi-way valve 1 forms different communication relationships in the first and third conducting modes, or in the third and second conducting modes.

[0088] For example, when the valve seat 3 includes 2*3 valve ports 31, Figure 5 When the valve core 2 rotates and the multi-way valve 1 is switched from the first conduction mode to the third conduction mode, or when the multi-way valve 1 is switched from the third conduction mode to the second conduction mode, different valve ports 31 will be connected.

[0089] When the valve core 2 includes one second communicating groove 222 , since the second communicating groove 222 is not applicable to the third conducting mode of the multi-way valve 1 , the communication relationship between at least one of the first conducting mode and the second conducting mode and the third conducting mode is different.

[0090] For example, when the valve seat 3 includes 2*3 valve ports 31, Figure 5, as shown in the expanded diagrams numbered 33-64. When the valve core 2 rotates, and the multi-way valve 1 is converted from the first conduction mode to the third conduction mode, or when the multi-way valve 1 is converted from the third conduction mode to the second conduction mode, different valve ports 31 will be connected. For example, in the prior art, after the valve core 2 rotates by an angle θ, the multi-way valve 1 is converted from the first conduction mode to the second conduction mode, and the multi-way valve 1 obtains different connection relationships. In the embodiment of the present application, after the valve core 2 rotates by an angle θ1, the multi-way valve 1 is converted from the first conduction mode to the third conduction mode, and the multi-way valve 1 can obtain different connection relationships, θ1<θ. In this way, when the valve core 2 needs to rotate to convert the connection relationship of the multi-way valve 1, the required torque is smaller and the conversion speed is fast.

[0091] In some embodiments, as Figure 1 、 Figure 6 and Figure 7 As shown, the first communicating surface 211 and the second communicating surface 212 include at least three first communicating grooves 221 arranged along the circumference of the valve core 2. Among the three first communicating grooves 221 arranged along the circumference of the valve core 2 on the first communicating surface 211 and the second communicating surface 212, at least one first communicating groove 221 and the other two first communicating grooves 221 have different axial sizes, or at least one first communicating groove 221 and the other two first communicating grooves 221 are staggered in the axial direction, and the first communicating surface 211 and the second communicating surface are staggered in the axial direction. The arrangement of the first communicating grooves 221 on the first communicating surface 211 and the second communicating surface 212 is different; or the first communicating surface 211 and the second communicating surface 212 are both provided with the second communicating grooves 222, and one first communicating groove 221 is provided on the first communicating surface 211 or the second communicating surface 212; or the first communicating surface 211 and the second communicating surface 212 are both provided with two first communicating grooves 221 and one second communicating groove 222, and the two second communicating grooves 222 respectively provided on the first communicating surface 211 and the second communicating surface 212 are arranged opposite to each other in the axial direction.

[0092] In these embodiments, the arrangement of the first communicating grooves 221 on the first communicating surface 211 and the second communicating surface 212 is different, and by adjusting the at least three first communicating grooves 221 arranged along the circumference of the valve core on the first communicating surface 211 and the second communicating surface 212, at least one first communicating groove 221 and the other two first communicating grooves 221 have different axial sizes or at least one first communicating groove 221 and the other two first communicating grooves 221 are staggered in the axial direction; or both the first communicating surface 211 and the second communicating surface 212 are provided with the second communicating groove 222, and one first communicating groove 221 is provided on the first communicating surface 211 or the second communicating surface 212. ; or the first connecting surface 211 and the second connecting surface 212 are both provided with two first connecting grooves 221 and one second connecting groove 222, and the two second connecting grooves 222 respectively provided on the first connecting surface 211 and the second connecting surface 212 are arranged opposite to each other in the axial direction, so that during the rotation of the valve core 2, the multi-way valve 1 can form different connecting modes in the first conducting mode, the second conducting mode and the third conducting mode, so that the multi-way valve 1 can obtain more conducting modes than the connecting surface 21 of the valve core 2, and the multi-way valve 1 can be applied to more scenarios to integrate multiple multi-way valves 1 with other different structures, reduce the number of molds, and save the preparation cost of the multi-way valve 1 and the vehicle.

[0093] The phrase "the first communicating grooves 221 on the first communicating surface 211 and the second communicating surface 212 are arranged in different ways" means that, if both the first communicating surface 211 and the second communicating surface 212 are provided with two first communicating grooves 221, the first communicating groove 221 on the first communicating surface 211, which is located away from the second communicating surface 212, and the first communicating groove 221 on the second communicating surface 212, which is located closer to the first communicating surface 211, are not arranged in a mirror image, and the first communicating groove 221 on the second communicating surface 212, which is located away from the first communicating surface 211, and the first communicating groove 221 on the first communicating surface 211, which is located closer to the second communicating surface 212, are not arranged in a mirror image. This ensures that the multi-way valve 1 has different communication relationships in the first conduction mode and the second conduction mode.

[0094] “At least one first communicating groove 221 has different axial dimensions from the other two first communicating grooves 221 ” means that at least one first communicating groove 221 can connect to a different number of valve ports 31 from the other two first communicating grooves 221 .

[0095] “At least one first communicating groove 221 and the other two first communicating grooves 221 are staggered in the axial direction” means that the minimum distances between the valve core 3 and at least one end in the axial direction and the three first communicating grooves 221 are unequal.

[0096] “In the three first communicating grooves 221 arranged along the circumferential direction of the valve core on the first communicating surface 211 and the second communicating surface 212”, specifically, when the first communicating surface 211 and the second communicating surface 212 include four circumferential rows of first communicating grooves 221, which are numbered 1, 2, 3 and 4 in sequence along the circumferential direction, then the first communicating grooves 221 numbered 1, 2 and 3 are the above-mentioned “three first communicating grooves 221 arranged along the circumferential direction of the valve core 2”, and if the first communicating grooves 221 numbered 1 and 2 are located on the first communicating surface 211, and the first communicating groove 221 numbered 3 is located on the second communicating surface 212, then the connection relationship between the first conduction mode and the third conduction mode of the multi-way valve 1 is different;

[0097] The first communicating grooves 221 numbered 2, 3, and 4 are the aforementioned "three first communicating grooves 221 arranged along the circumference of the valve core 2." If the first communicating grooves numbered 3 and 4 are located on the second communicating surface 212, and the first communicating groove 221 numbered 2 is located on the first communicating surface 211, then the communication relationship between the second conducting mode and the third conducting mode of the multi-way valve 1 will be different. In addition, the arrangement of the first communicating grooves 221 on the first communicating surface 211 and the second communicating surface 212 is different, that is, the communication relationship between the first conducting mode and the second conducting mode is different, thereby ensuring that the multi-way valve 1 has different communication relationships in the first conducting mode, the second conducting mode, and the third conducting mode. Figure 5 , numbers 2, 3, 5, 8, 10, 12, 13, and 15 are shown in the expanded view.

[0098] The first connecting surface 211 and the second connecting surface 212 are both provided with a second connecting groove 222. Since the second connecting groove 222 is not used in the third conduction mode, it is possible to make at least one of the first conduction mode or the second conduction mode have a different connection relationship with the third conduction mode; a first connecting groove 221 is provided on the first connecting surface 211 or the second connecting surface 212, which means that one of the first connecting surface 211 and the second connecting surface 212 is provided with a first connecting groove 221, and the other is provided with two second connecting grooves 222. The arrangement of the first connecting grooves 221 of the first connecting surface 211 and the second connecting surface 212 is different, so the connection relationship between the first conduction mode, the second conduction mode and the third conduction mode of the multi-way valve 1 is different. Figure 5 , as shown in the expanded diagrams of numbers 51-53 and 59-61.

[0099] The first connecting surface 211 and the second connecting surface 212 are both provided with two first connecting grooves 221 and one second connecting groove 222. Since the second connecting groove 222 is not used in the third conduction mode, it is possible to make at least one of the first conduction mode or the second conduction mode have different connection relationships with the third conduction mode; and the two second connecting grooves 222 respectively provided on the first connecting surface 211 and the second connecting surface 212 are arranged opposite to each other in the axial direction, so the arrangement of the first connecting grooves 221 on the first connecting surface 211 and the second connecting surface 212 is different, and the connection relationships between the first conduction mode, the second conduction mode and the third conduction mode of the multi-way valve 1 are different. Figure 5 , shown in the expanded view of numbers 56 and 63.

[0100] In some embodiments, as Figure 1 and Figure 3 As shown, along the circumferential direction of the valve core 2, the first communication grooves 221 are evenly spaced apart.

[0101] In these embodiments, the first communicating grooves 221 are evenly spaced along the circumferential direction of the valve core 2 , so that when the multi-way valve 1 is in the third conduction mode, the first communicating grooves 221 can be aligned with the valve port 31 of the valve seat 3 .

[0102] The first communicating grooves 221 of each communicating surface 21 are arranged at equal intervals along the circumferential direction of the valve core 2. Specifically, when the valve seat 3 includes 2*m valve ports 31, in the first communicating surface 211 and the second communicating surface 212, the spacing between two adjacent first communicating grooves 221 in the circumferential direction of the valve core 2 is equal to the spacing between two adjacent rows of valve ports 31 along the circumference of the valve core 2 on the valve seat 3, so that when the multi-way valve 1 is in the third conduction mode, the two first communicating grooves 221 respectively arranged on the first communicating surface 211 and the second communicating surface 212 can be aligned with the valve ports 31.

[0103] Optionally, the connecting surfaces 21 are evenly spaced along the circumferential direction of the valve core 2 , the central angles corresponding to the connecting surfaces 21 are the same, and the first connecting grooves 221 are evenly spaced along the circumferential direction of the valve core 2 .

[0104] In some embodiments, as Figure 1 and Figure 2 As shown, the valve seat 3 includes at least one side wall in the axial direction of the valve core 2, and a peripheral wall connected to the side wall. The side wall and the peripheral wall enclose a chamber. The valve core 2 is located in the chamber. A first stopper (not shown in the figure) is provided on the side wall. A second stopper 24 is provided on the side of the valve core 2 facing the side wall. The first stopper is used to stop the second stopper 24 in the circumferential direction of the valve core 2.

[0105] In these embodiments, the valve seat 3 includes at least one side wall in the axial direction of the valve core 2, and a peripheral wall connected to the side wall. The side wall and the peripheral wall enclose a chamber. The valve core 2 is located in the chamber. A first stop member is provided on the side wall, and a second stop member 24 is provided on the side of the valve core 2 facing the side wall. During the rotation of the valve core 2, the first stop member can stop the valve core 2 through the second stop member 24 to facilitate the adjustment of the rotation direction of the valve core 2, and to facilitate the planning of the order of the various conduction modes of the multi-way valve 1 to avoid the problem of reversal of the valve core 2.

[0106] In some embodiments, a sliding groove is provided on the side surface of the side wall facing the chamber, the second stop 24 is accommodated in the sliding groove, the second stop 24 is movably arranged relative to the sliding groove, and the first stop is arranged in the sliding groove, or a sliding groove is provided on the side surface of the valve core 2 facing the side wall, the second stop 24 is arranged in the sliding groove, the first stop is accommodated in the sliding groove, the first stop is movably arranged relative to the sliding groove, and the first stop and the second stop 24 can stop each other in the sliding groove.
