Title:
MULTI-WAY VALVE, THERMAL MANAGEMENT SYSTEM, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/012165
Kind Code:
A1
Abstract:
A multi-way valve, a thermal management system and an electric vehicle. The multi-way valve comprises a housing (11), a gear train (12), liquid input channels (13) and liquid output channels (14). A hollow portion of the housing (11) is partitioned into a plurality of chambers (15), wherein each chamber (15) accommodates an end face valve (16) and the corresponding liquid output channel (14), each chamber (15) communicates with the corresponding liquid input channel (13), and the liquid input channel communicates with the liquid output channel (14) in the corresponding chamber (15). Each end face valve (16) comprises a control opening (161) and a non-opening portion (162); and the end face valve (16) can rotate about an axis thereof, and completely covers a liquid output opening (141) of the liquid output channel so as to control the opening or closing of the liquid output channel. The gear train (12) comprises one driving wheel (121) and a plurality of driven wheels (122), wherein the driven wheels (122) are connected to the end face valves (16) in a one-to-one correspondance, so as to control the end face valves to rotate. The multi-way valve is provided with the gear train, such that the end face valves can be controlled merely by one actuator, the design of an electronic control unit is thus simplified, thereby reducing the cost and saving on the space.
