Description

Technical Field

[0001] This utility model relates to the field of water valves, specifically to a proportional four-way valve and a thermal management module. Background Technology

[0002] The thermal management system of new energy vehicles is designed with multiple circulation loops. Based on the principle of vehicle thermal management, multiple water valves are needed to connect and seal water circuits under various operating conditions. In currently available car models, it is common to see a combination of multiple on / off valves. In order to improve the driving range, new energy vehicles have increasingly more requirements for vehicle thermal management design. From the perspectives of cost saving, weight reduction, and space utilization, it is even more important to integrate multiple on / off valves into a smaller number of multi-functional water valves.

[0003] In view of this, it is necessary to improve the existing proportional four-way valve to solve the above problems. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] 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.

[0019] 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.

[0020] like Figures 1 to 4 As shown, the proportional four-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.

[0021] The valve core 1 is provided with a sealing block 11 and a first flow channel 12 and a second flow channel 13 that are interconnected. The first flow channel 12 is columnar and is located in the middle of the valve core 1. The second flow channel 13 is fan-shaped and surrounds the first flow channel 12. The first flow channel 12 and the second flow channel 13 are formed by the side wall of the valve core 1 and the sealing block 11.

[0022] The valve cover 3 is provided with a first flow channel port 31 for communicating with the first flow channel 12 and a plurality of second flow channel ports 32 arranged around the first flow channel port 31. The valve core 1 has a first state in which the second flow channel 13 is connected to a second flow channel port 32 and a second state in which the second flow channel 13 is proportionally connected to two first flow channels 13 and two second flow channels 13.

[0023] The proportional connectivity here means that only a portion of the second flow channel 32 is connected to one of the second flow channels 13 in the circumferential direction, while another portion is blocked by the blocking block. Flow control is achieved by adjusting the proportion of the blocking area.

[0024] In this embodiment, by providing a first flow channel 12 and a second flow channel 13 on the valve core 1, rotating the valve core 1 can make the valve core 1 be in different states, thereby realizing multiple flow modes.

[0025] In this embodiment, a plurality of second flow channels 32 are arranged in a circular array. Preferably, the central angle of the second flow channel 32 coincides with the central angle of the second flow channel 13, so that when the valve core 1 is in the second state, the second flow channel 32 can completely overlap with the second flow channel 13.

[0026] In other embodiments, the central angle of the second flow channel 13 may be smaller than that of the second flow channel opening 32, and when the valve core 1 is in the second state, the second flow channel 13 is fully exposed from the second flow channel opening 32.

[0027] Furthermore, in this embodiment, there are three second flow channel openings 32. The central angle of the second flow channel 13 is 120 degrees, and the central angle of the second flow channel opening 32 is also 120 degrees. Due to processing errors, the actual central angles of the second flow channel 13 and the second flow channel opening 32 may deviate by 5-10 degrees. The central angle of the sealing block 11 is 240 degrees.

[0028] In this embodiment, the sealing block 11 is provided with a limiting strip 14 protruding toward the valve cover 3, and the limiting strip 14 passes through the first flow channel opening 31 axially. The limiting strip 14 can play a role in radial limiting.

[0029] The valve cover 3 is provided with a sealing gasket 33 on the side facing the valve core 1. The sealing gasket 33 is used to prevent the valve core 1 from moving radially during rotation relative to the valve cover 3.

[0030] In order to improve the life of the valve core 1, in this embodiment, the proportional four-way valve 100 further includes a wear-resistant plate 4 that abuts against the valve body 2 and the valve core 1 along the axial direction.

[0031] To achieve rotation of the valve core 1, the valve core 1 has a connecting shaft 15 protruding towards the end away from the valve cover 3. The connecting shaft 15 passes axially through the valve body 2. The proportional four-way valve 100 also includes a sealing ring 5 disposed between the valve body 2 and the connecting shaft 15. The proportional four-way valve 100 also includes an actuator connected to the connecting shaft 15. When the actuator operates, it can drive the connecting shaft 15 to rotate, thereby driving the valve core 1 to rotate. The sealing ring 5 can prevent fluid from the valve core 1 and the valve body 2 from entering the actuator along the connecting shaft 15.

[0032] In this embodiment, the three second flow channels 32 are designated as second flow channel 32, second flow channel 32, and third flow channel 32, respectively. The proportional four-way valve 100 has six operating modes: First working mode: The valve core 1 is in the first state, and the first second flow channel port 32 is connected to the second flow channel 13, and the first flow channel port 31 is connected to the first flow channel 12; Second working mode: The valve core 1 is in the first state, and the second flow channel port 32 is connected to the second flow channel 13, and the first flow channel port 31 is connected to the first flow channel 12; Third working mode: The valve core 1 is in the first state, and the third second flow channel port 32 is connected to the second flow channel 13, and the first flow channel port 31 is connected to the first flow channel 12; Fourth working mode: The valve core 1 is in the second state, the first second flow channel port 32 and the second second flow channel port 32 are proportionally connected through the second flow channel 13, and the first flow channel port 31 is connected to the first flow channel 12; Fifth working mode: The valve core 1 is in the second state, the second flow channel port 32 and the third flow channel port 32 are proportionally connected through the second flow channel 13, and the first flow channel port 31 is connected to the first flow channel 12; Sixth working mode: The valve core 1 is in the second state, the first second flow channel port 32 and the third second flow channel port 32 are proportionally connected through the second flow channel 13, and the first flow channel port 31 is connected to the first flow channel 12.

[0033] This utility model also includes a thermal management module, which includes at least one of the proportional four-way valves 100.

[0034] The proportional four-way valve 100 and thermal management module of this utility model can achieve multiple working modes by setting up a first flow channel 12 and a second flow channel 13 that are interconnected. It occupies a small volume, has a high space utilization rate, and is simple to control. It can meet the proportional adjustment of one inlet and three outlets and can realize more working modes of thermal management system.

[0035] 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.

[0036] 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.
