The thermal fluid integrated module of the thermal management system mainly realizes the switching of thermal fluid through a combination of multiple water valves, thereby achieving rational use of the heat of the entire vehicle.

[0003] Existing heat transfer fluid integrated modules often need to use a combination of multiple three-way water valves and four-way water valves to achieve the switching of various heat transfer fluid modes. Many parts are required, which not only increases the cost, but also increases the pipes that need to be connected, increases the structure of the entire heat transfer fluid integrated module, and further increases the complexity of the vehicle structure layout. In order to reduce the parts of the water valve, existing manufacturers have designed a double valve core structure to control the switching of heat transfer fluids in the heat transfer fluid integrated module.

[0004] The existing double valve core structure is mainly composed of a valve body, two valve cores, and a linkage mechanism. The two valve cores are coaxially arranged in the valve body.

By adjusting the connection between the flow channel on the core and the valve body interface on the valve body, the output state of the valve body is adjusted. Although the heat transfer fluid switching function can be achieved, the existing double valve core still has some shortcomings, such as:

[0005] 1) Two valve cores are used, which increases the volume of the water valve structure, increases the components of the water valve structure, increases the cost investment, and also increases the assembly process of the water valve structure;

When the embodiment is specifically implemented, the discontinuous sealing gasket 4 is provided with an interface 45 vertically and tightly connected to the two edges of the sealing gasket 4 at the interruption. At the angle of each set working state, the valve core 2 can be tightly fitted with the interface 45 of the sealing gasket 4 over a large area through one of the protrusions 27 designed on the valve core 2, so that the pressure fluid inside the valve core 2 can be prevented from leaking from the interface 45 of the sealing gasket 4. Therefore, the multi-way valve of the utility model is sealed at the interface 45 of the sealing gasket 4. The flow channel design of the valve core 2 ensures five working states of the valve core 2. The multiple protrusions 27 of the valve core 2 are tightly fitted with the interface 45 of the sealing gasket, thereby ensuring the sealing performance of the sealing gasket 4. Since the sealing gasket 4 has deformation and inherent tension in the circumferential direction and is not tightly combined with the valve body 1, it is easy to leak. Therefore, the utility model is fixed with a plurality of ribs 44 in the circumferential direction of the sealing gasket 4. The plurality of ribs 44 can enhance the airtightness of the sealing gasket 4 and ensure the sealing performance of the sealing gasket 4.
