[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figures 1 to 4 As shown, the proportional multi-way valve 100 of this utility model includes a valve core 1, a valve body 2 for housing the valve core 1, and a valve cover 3 disposed on one side of the valve body 2 for covering the valve core 1.

[0037] The valve core 1 is provided with a blocking block 11 and a first flow channel 12 and a second flow channel 13 that are not connected to each other. The first flow channel 12, the second flow channel 13 and the blocking block 11 have the same shape and are arranged in a circular array.

[0038] The valve cover 3 has six flow channels 31 arranged in an array along the circumferential direction. The valve core 1 has a first state and a second state. When the valve core 1 is in the first state, the first flow channel 12 and the second flow channel 13 are respectively connected to two flow channels 31. When the valve core 1 is in the second state, the first flow channel 12 and the second flow channel 13 are respectively fully connected to one flow channel 31, and the two flow channels 31 adjacent to the flow channel 31 are proportionally connected.

[0039] In this embodiment, by setting the first flow channel 12, the second flow channel 13 and the blocking block 11 arranged in an array inside the valve core 1, different connection methods can be achieved by rotating the valve core 1, thereby realizing multiple connection modes.

[0040] In this embodiment, the first flow channel 12, the second flow channel 13, and the blocking block 11 are all fan-shaped. Correspondingly, the flow port 31 on the valve cover 3 is also fan-shaped with the same radial width as the first flow channel 12 and the second flow channel 13. In other embodiments, the first flow channel 12, the second flow channel 13, the blocking block 11, and the flow port 31 may also be fan-shaped.

[0041] In this embodiment, a columnar anti-cavitation column 14 is formed in the middle of the valve core 1. The first flow channel 12 and the second flow channel 13 are separated by a partition 15. The first flow channel 12 and the second flow channel 13 are both formed by the sealing block 11, the anti-cavitation column 14, the partition 15 and the outer wall of the valve core 1.

[0042] In addition, in this embodiment, the central angles of the first flow channel 12, the second flow channel 13, and the sealing block 11 are all 120 degrees. It should be noted that due to process errors and the presence of the partition 15, the angles of the first flow channel 12, the second flow channel 13, and the sealing block 11 may have an error of less than 10 degrees.

[0043] In other embodiments, the central angles of the first flow channel 12, the second flow channel 13, and the blocking block 11 can be set differently. This is as long as different operating modes can be achieved by rotating the valve core 1 in conjunction with the flow channel opening 31.

[0044] Corresponding to the first flow channel 12 and the second flow channel 13, the central angle of the flow channel opening 31 is approximately 60 degrees, thereby ensuring that two adjacent flow channel openings 31 can be simultaneously connected to the first flow channel 12 or the second flow channel 13.

[0045] The valve cover 3 has an inner sealing gasket 32 ​​on the side facing the valve core 1 and an outer sealing gasket 33 on the side away from the valve core 1. The inner sealing gasket 32 ​​and the outer sealing gasket 33 are arranged around the flow channel opening 31 to ensure the sealing of the flow channel opening 31.

[0046] The proportional multi-way valve 100 also includes a wear-resistant plate 4 that abuts against the valve body 2 and the valve core 1 along the axial direction. The wear-resistant plate 4 can prevent wear and damage caused by the valve core 1 rotating relative to the valve body 2 for a long time.

[0047] In this embodiment, to achieve the rotation of the valve core 1, the valve core 1 has a connecting shaft 16 protruding towards the end away from the valve cover 3. The connecting shaft 16 passes through the valve body 2 axially. The proportional multi-way valve 100 also includes a sealing ring 5 disposed between the valve body 2 and the connecting shaft 16. The proportional multi-way valve 100 also includes an actuator 6 connected to the connecting shaft 16. The operation of the actuator 6 can drive the rotation of the valve core 1.

[0048] In this embodiment, the flow channels 31 are sequentially designated as flow channel 1, flow channel 2, flow channel 31, flow channel 31, flow channel 4, flow channel 5, and flow channel 6 along the circumferential direction.

[0054] Sixth working mode: The valve core 1 is in the second state, the fifth flow channel port 31 is fully connected to the first flow channel 12, the sixth flow channel port 31 and the fourth flow channel port 31 are proportionally connected to the first flow channel 12, the second flow channel port 31 is fully connected to the second flow channel 13, and the first flow channel port 31 and the third flow channel port 31 are proportionally connected to the second flow channel 13;

[0055] Seventh working mode: The valve core 1 is in the first state, the fourth flow port 31 and the fifth flow port 31 are connected to the first flow channel 12, and the sixth flow port 31 and the first flow port 31 are connected to the second flow channel 13;

[0056] Eighth working mode: The valve core 1 is in the second state, the fourth flow channel port 31 is fully connected to the first flow channel 12, the fifth flow channel port 31 and the third flow channel port 31 are proportionally connected to the first flow channel 12, the first flow channel port 31 is fully connected to the second flow channel 13, and the sixth flow channel port 31 and the second flow channel port 31 are proportionally connected to the second flow channel 13;

[0057] Ninth working mode: The valve core 1 is in the first state, the third flow port 31 and the fourth flow port 31 are connected to the first flow channel 12, and the fifth flow port 31 and the sixth flow port 31 are connected to the second flow channel 13;

[0058] Tenth working mode: The valve core 1 is in the second state, the third flow channel 31 is fully connected to the first flow channel 12, the fourth flow channel 31 and the second flow channel 31 are proportionally connected to the first flow channel 12, the sixth flow channel 31 is fully connected to the second flow channel 13, and the fifth flow channel 31 and the first flow channel 31 are proportionally connected to the second flow channel 13.

[0061] It should be noted that not only one flow port 31 can connect to one pipe. In practical applications, multiple flow ports 31 can connect to one pipe.

[0062] The proportional connectivity here means that only a portion of the flow channel 31 is connected to one of the first flow channel 12 and the second flow channel 13 in the circumferential direction, while another portion is blocked by a blocking block or connected to the other of the first flow channel 12 and the second flow channel 13. Flow control is achieved by adjusting the proportion of the connectivity area.

[0064] The proportional multi-way valve 100 and thermal management module of this utility model can realize multiple working modes by setting the first flow channel 12 and the second flow channel 13 and rotating the valve core 1. It occupies a small volume, has high space utilization, is simple to control, and can realize more working modes of thermal management system.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
