Kind Code:
A1
Abstract:
A multi-channel switching valve, a thermal management system, and a vehicle. The multi-channel switching valve (100) comprises: a housing (10), a plurality of circulation through holes (11) being provided in the circumferential direction of the housing (10); a valve core (20), rotatably arranged in the housing (10), the valve core (20) being provided with at least one switching channel (21), the switching channel (21) being in communication with two of the circulation through holes (11), and the valve core (20) being configured so that the switching channel (21) is in switchable communication with different circulation through holes (11) when the valve core (20) rotates; and a sealing member (30), comprising a body (31), the body (31) being provided with a plurality of relief through holes (311), the plurality of relief through holes (311) being in communication with the plurality of circulation through holes (11) in a one-to-one correspondence, the body (31) being formed as an integrally machined member in the form of an arc-shaped plate, the central angle of the sealing member (30) being less than or equal to 180°, and the sealing member (30) being in contact with the valve core (20) and the housing (10), separately. According to the multi-channel switching valve, the sealing performance of the sealing member can be enhanced.
