[0002] At present, the structures of three-way and four-way water valves in the market are mature and widely used in the thermal management modules of new energy vehicles. However, they cannot reduce the complex layout space of the vehicle design and the complexity of the pipelines. At the same time, there are more switching mode requirements in new energy vehicles to improve the driving experience.

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

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] As Figures 1 to 4 shown, the thermal management module of the present utility model includes a multi-way valve 100, and the number of the multi-way valve 100 is one or more.

[0024] The multi-way valve 100 of the present invention includes a valve body 1, a valve core 2 rotatable relative to the valve body 1 and arranged inside the valve body 1, a gasket 3, an O-ring 4, a cover plate 5, a K-ring 6, and an actuator 7.

[0025] The valve body 1 includes a bottom plate 11 and a side wall 12. A plurality of flow ports 13 are provided on one side of the valve body 1. Specifically, the flow ports 13 are penetrated and opened on the bottom plate 11. The side wall 12 extends from the edge of the bottom plate 11 towards one side, and the cover plate 5 is arranged at one end of the valve body 1 away from the flow ports 13. Further, the cover plate 5 is fixedly connected to the side of the side wall 12 away from the bottom plate 11.

[0026] The actuator 7 is arranged on the side of the cover plate 5 away from the flow ports 13. The actuator 7 passes through the cover plate 5 to be connected to the valve core 2 to drive the valve core 2 to rotate. The K-ring 6 is sleeved on the connecting shaft of the valve core 2 and the actuator 7 to play a sealing role.

[0027] The valve core 2 is provided with a flow channel 21 protruding towards the direction of the flow ports 13 and used for communicating with the flow ports 13. Each flow channel 21 is used for communicating with two of the flow ports 13.

[0028] The number of the flow ports 13 is greater than twice the number of the flow channels 21. Thus, some of the flow ports 13 are not communicated with the flow channels 21 but are directly communicated with the valve body 1, so that the liquid fills the entire cavity where the valve core 2 is located, realizing that there is no pressure imbalance in the valve core 2 in the valve body 1, thereby ensuring that the leakage amount is small when the valve core 2 is operating.

[0029] In this embodiment, the fluid ports 13 are arranged in a circumferential array around the axis of the valve body 1. In this embodiment, the number of the fluid ports 13 is eight, and the number of the flow channels 21 is three. Thus, at least two fluid ports 13 are always exposed, allowing the liquid to enter the valve body 1.

[0030] The gasket 3 is arranged at one end of the flow channel 21 facing the fluid port 13 for abutting against the valve body 1. The gasket 3 includes a connecting portion 31 protruding into the flow channel 21 and an abutting portion 32 protruding outside the flow channel 21. In this embodiment, since the flow channel 21 of the valve core 2 does not need to directly abut against the valve body 1, the valve body 1 can be made of PA66+GF30 (nylon + glass fiber). In order to improve the sealing effect, the gasket 3 is made of PTFE material, and the valve body 1 is made of PPS material. Such a material configuration makes the cost lower.

[0031] The O-ring 4 is arranged between the connecting portion 31 and the flow channel 21. Further, a receiving groove 33 is formed by surrounding and recessing on the connecting portion 31, and the O-ring 4 is received in the receiving groove 33. The O-ring 4 can prevent the liquid from entering between the connecting portion 31 and the flow channel 21.

[0032] The multi-way valve 100 and the thermal management module of the present utility model can reliably meet the functional requirements of the product in multiple mode operating conditions by arranging the gasket 3, can replace multiple four-way valves and multiple three-way valves, and make the pipeline connection simpler.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0034] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
