It will be appreciated that the modes described herein may be a series of changing modes, such as a switching valve, or a continuously changing mode, such as a proportional valve.

As shown in fig. 2 (the black bold lines in the drawing indicate the medium flow paths), medium may also enter the flow channels 15, and the medium flow through the flow channels 15 increases the likelihood of the multiway valve 100.

In some examples of the present invention, the communication passage 21 may be provided to communicate two adjacent communication ports 11, facilitating production of the valve cartridge 20, for example, two communication ports 11 adjacent.

The valve core 20 rotates to communicate two of the circulation ports 11 through the communication channel 21 and/or communicate two of the circulation ports 11 through the circulation channel 15 and the communication channel 21, and multiple modes are realized by rotating the valve core 20, so that more modes are realized under the same volume compared with the mode of multiple multi-way valves in the related art, and the control difficulty and the control cost are reduced. That is, the rotary valve body 20 may be configured such that the communication passage 21 that is not initially connected to the communication ports 11 is connected to two of the communication ports 11, and of course, it may be configured such that the communication passage 21 that is initially connected to two of the communication ports 11 is connected to the other two of the communication ports 11; or, the rotary valve core 20 may be a circulation channel 15 which is not communicated with the circulation ports 11 at the beginning and a communication channel 21 is communicated with two of the circulation ports 11, and the circulation channels 15 are added on the basis that the communication channels 21 are changed to be communicated with different circulation ports 11, so that the flow paths of the medium are more diversified, a multi-layer composite flow space is constructed, and the use under complex working conditions is realized; still alternatively, the valve core 20 rotates to communicate two of the flow ports 11 through the communication passage 21 and two of the flow ports 11 through the flow passage 15 and the communication passage 21, further increasing the selectable modes, further improving the adaptability of the multi-way valve 100.

For example, when the multi-way valve 100 is placed on a horizontal plane, the rotation axis direction of the valve core 20 is in the up-down direction, six flow openings 11 are arranged in three rows and two columns on the valve housing 10, and when the first communication channel 21 communicates the inlet of the flow channel 15 with the flow openings 11 of the first row and the second column, and the second communication channel 21 communicates the outlet of the flow channel 15 with the flow openings 11 of the third row and the second column, a medium can enter the multi-way valve 100 from the flow openings 11 of the first row and the second column, flow through the first communication channel 21, the flow channel 15, the second communication channel 21, and then flow out of the multi-way valve 100 from the flow openings 11 of the third row and the second column.

the valve comprises a valve housing, wherein a plurality of circulation ports and at least one circulation channel are formed in the valve housing, and the circulation channel is provided with an inlet and an outlet which are positioned on the inner peripheral wall of the valve housing;

the valve core is rotatably arranged in the valve shell, the valve core is provided with a communication channel, the communication channel extends along the peripheral wall of the valve core, and the valve core rotates to communicate two of the circulation ports through the communication channel and/or to communicate two of the circulation ports through the communication channel and the communication channel.

2. The multi-way valve of claim 1, wherein at least one of the flow channels extends in a direction parallel to the axis of rotation of the spool.

3. The multi-way valve according to claim 1, wherein the flow passage is provided on both sides of the plurality of flow ports in a rotational direction of the spool.

4. The multi-way valve of claim 1, wherein the communication channels are a plurality of.

5. The multi-way valve according to claim 4, wherein the extending directions of at least two of the communication passages are different.

6. The multi-way valve of claim 5, wherein a portion of the communication passage extends in an axial direction of the spool, and wherein a portion of the communication passage extends in a circumferential direction of the spool.

7. The multi-way valve of claim 1, wherein the valve housing is provided with a connection plane, the connection plane being disposed parallel to the rotational axis of the valve spool, and wherein the plurality of flow ports are disposed on the connection plane.

8. The multiport valve of claim 7, wherein a plurality of said flow ports are arranged in a plurality of rows and columns and at uniform intervals.

9. The multi-way valve of claim 1, wherein the spool has a diameter of less than 150mm.

10. The multi-way valve of any one of claims 1-9, further comprising a seal disposed between the valve housing and the valve spool, the seal providing a relief port for relieving the flow port.

11. The multi-way valve of claim 10, wherein said seal is secured to an inner wall of said valve housing, said relief ports being a plurality, said plurality of relief ports being disposed in correspondence with said plurality of flow ports and said plurality of inlet and outlet ports.

12. A thermal management system, comprising: a multi-way valve according to any one of claims 1 to 11.

13. The thermal management system of claim 12, comprising: the flow control device comprises a flow control plate, a valve core and a heat management system, wherein a plurality of flow channels for flowing media are arranged in the flow control plate, a multi-way valve is arranged on the flow control plate, the flow channels are respectively connected with a plurality of flow ports, and the valve core rotates to control the flow channels to be communicated in a changing mode so as to control the heat management system to change modes.

14. A vehicle comprising a thermal management system according to claim 12 or claim 13.
