[0023] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Embodiment one

[0025] The following refers to Figures 1-5 A multi-way valve according to the utility model embodiment is described, which comprises a valve seat 1 and a valve core 2. The valve seat 1 comprises a side wall 11 and a first bottom surface 12. The side wall 11 is cylindrical and is arranged in a circumferential direction. The first bottom surface 12 is connected to one end of the side wall 11. The other end of the side wall 11 is open. The valve core 2 extends into the valve seat 1 from the open end of the side wall 11. The valve core 2 is coaxially arranged with the valve seat 1. When the valve core 2 rotates around its own axis, it rotates in the center of the valve seat 1. The side wall 11 of the valve seat 1 is uniformly provided with a plurality of valve ports 13 in the circumferential direction. An interface 4 that communicates with the outside is arranged on the first bottom surface 12 of the valve seat 1. A flow channel 21 is arranged in the valve core 2. The middle part of the flow channel 21 is of a communicating structure. The valve core 2 can rotate around its own axis in the valve seat 1. When the valve core 2 rotates to a predetermined angle, the flow channel 21 communicates with the interface 4 and the plurality of valve ports 13. The predetermined angle is the rotation angle required when the flow channel 21 rotates to the position of the interface 4. The valve port 13 is a flow port of the valve seat 1. Therefore, when the valve core 2 rotates to the predetermined angle and the plurality of valve ports 13 are connected with the interface 4, a flow branch is formed between the plurality of valve ports 13, the interface 4 and the flow channel 21, thereby realizing the opening of the branch. When the valve core 2 does not rotate to the predetermined angle, the plurality of valve ports 13 are not connected with the interface 4, thereby realizing the closing of the branch. In this embodiment, the opening and closing of the branch can be realized only by controlling the rotation of the valve core 2, without the need to control the valve seat 1 by using a motor. The control mode is simple, and only one motor is needed, thereby reducing the cost.

[0026] It should be noted that one end of the interface 4 of the valve seat 1 is arranged on the first bottom surface 12 as an opening arranged on the first bottom surface 12. The other end of the interface 4 extends to the side away from the valve core 2. The interface 4 is of a middle-through structure with two open sides, which is convenient for connecting other branches in the thermal management system.

[0027] In one embodiment, reference is made toFigure 4 and 5 The valve core 2 comprises a partition plate 22, a first baffle 23 and a second baffle 24, the partition plate 22 is arranged between the first baffle 23 and the second baffle 24, a first end of the partition plate 22 is connected with the first baffle 23, a second end of the partition plate 22 is connected with the second baffle 24, the partition plate 22 is provided in plurality, a flow channel 21 is formed between the plurality of partition plates 22, the flow channel 21 is formed by the partition plate 22 and the first baffle 23 and the second baffle 24 together, it is to be noted that in order to ensure the communication between the plurality of valve ports 13, one end of the partition plate 22 abuts against the inner wall of the side wall 11.

[0028] In one embodiment, the first baffle 23 abuts against the first bottom surface 12, referring to Figure 4 A notch 3 is formed on the first baffle 23, the notch 3 is matched with the interface 4, the flow channel 21 is communicated with the interface 4 through the notch 3, further, no opening is formed on the first baffle 23 except the notch 3, when the valve core 2 rotates around the axis thereof, when it rotates to a predetermined angle, the position of the notch 3 corresponds to the position of the interface 4, the flow channel 21 is communicated with the interface 4, thereby the plurality of valve ports 13 is communicated with the interface 4, a branch is formed, and the opening of the branch is realized; after the opening of the branch, the valve core 2 is continuously rotated, the position of the notch 3 does not correspond to the position of the interface 4, at this time, the interface 4 abuts against the first baffle 23, at this time, the flow channel 21 cannot be communicated with the interface 4, thus the closing of the branch is realized, by forming the notch 3 matched with the interface 4 on the first baffle 23, the opening and closing of the branch are realized.

[0029] In one embodiment, notches 3 are formed on both ends of the flow channel 21, when the valve core 2 rotates to a predetermined angle, one notch 3 is communicated with the interface 4, when the valve core 2 rotates, the flow channel 21 communicates different valve ports 13, since the notch 3 is formed on both ends of the flow channel 21, in this embodiment, the valve ports 13 on the side wall 11 are provided in eight, which are provided as first to eighth valve ports, the notches 3 are provided in two, which are provided as first and second notches, when the flow channel 21 communicates two valve ports 13 which are spaced apart, the interface 4 is arranged at the position of the seventh valve port, when the first notch is communicated with the interface 4 by rotating the valve core 2, the flow channel 21 communicates the seventh valve port and the second valve port, when the second notch is communicated with the interface 4 by rotating the valve core 2, the flow channel 21 communicates the seventh valve port and the fourth valve port, the notches 3 arranged on both ends of the flow channel 21 can realize the adjustment of different flow branches by rotating the valve core 2.

[0030] In one embodiment, the flow channel 21 connects at least two valve ports 13, and the flow channel 21 connects at least two valve ports 13 to the interface 4, realizing the three-way function of the multi-way valve flow branch. The two valve ports 13 connected by the flow channel 21 are not adjacent. If the flow channel 21 connects two adjacent valve ports 13, for example, when the valve core 2 rotates to connect the first notch with the interface 4, the flow channel 21 connects the seventh valve port and the sixth valve port. When the valve core 2 rotates to connect the second notch with the interface 4, the flow channel 21 connects the seventh valve port and the eighth valve port. In this way, when rotating, after the first notch connects with the interface 4, continuing to rotate will cause the second notch to connect with the interface 4. If you want to close the flow branch, you must rotate the valve core 2 in the opposite direction, which has certain requirements for the control process. Therefore, the flow channel 21 not connecting two adjacent valve ports 13 can simplify the control process of opening and closing different flow branches.

[0031] In one embodiment, the included angle between the valve ports 13 connected to the flow channel 21 is less than 180°. The included angle between the valve ports 13 refers to the minimum included angle between two valve ports 13. Taking 8 valve ports 13 as an example, when the flow channel 21 is connected to a valve port 13 with a gap of one, the interface 4 is set at the position of the seventh valve port. When the valve core 2 rotates to connect the first notch with the interface 4, the flow channel 21 connects the seventh valve port and the first valve port. When the valve core 2 rotates to connect the second notch with the interface 4, the flow channel 21 connects the seventh valve port and the fifth valve port, which can realize the adjustment of different flow branches. However, when the valve ports 13 connected to the flow channel 21 are located on the same diameter of the valve seat 1, for example, when the flow channel 21 connects the seventh valve port and the third valve port, when the valve core 2 rotates, since notches 3 are set at both ends of the flow channel 21, when the first notch or the second notch connects with the interface 4, the flow channel 21 connects the seventh valve port and the third valve port. Therefore, the flow channel 21 does not connect to the two valve ports 13 that are set opposite to each other, which further ensures the realization of the adjustment of different flow branches.

[0032] In one embodiment, a rotating shaft 5 is provided on the bottom surface of the second baffle 24. The rotating shaft 5 is located on the side of the second baffle 24 away from the first baffle 23. The rotating shaft 5 is located at the center of the valve core 2 and extends axially. The rotating shaft 5 is connected to an external drive motor. The drive motor rotates the rotating shaft 5, thereby driving the valve core 2 to rotate within the valve seat 1.

[0033] In one embodiment, one end of the interface 4 is arranged circumferentially along the first bottom surface 12, and the central angle of the interface 4 is adapted to the central angle of the valve port 13. The interface 4 is opened on the half side of the first bottom surface 12 rather than in the middle, ensuring that the notch 3 can only be connected to the interface 4 after the valve core 2 is rotated, so that the flow branch can be opened or closed by the rotation of the valve core 2.

[0034] The nine-way valve of the utility model, working principle is: the valve core 2 of inside setting flow channel 21 is inserted into the valve seat 1, the side wall 11 of valve seat 1 is provided with multiple valve ports 13 along the circumference, flow channel 21 is communicated with multiple valve ports 13, valve core 2 can rotate along its axis in valve seat 1, the first bottom surface 12 of valve seat 1 is provided with interface 4, when valve core 2 rotates to the predetermined angle, multiple valve ports 13 are communicated with interface 4, open the communication of flow branch, when not rotating to the predetermined angle, multiple valve ports 13 are not communicated with interface 4, and flow branch is closed, further realize the effect of adjusting flow branch opening and closing, and in addition, only need to rotate valve core 2 in this embodiment, and the adjustment of branch can be realized, control is simple, and the cost is lower.
