Document Type and Number:
WIPO Patent Application WO/2022/262428
Kind Code:
A1
Abstract:
Provided are a thermal management system for a fuel cell hybrid electric vehicle, a method, a vehicle and a medium. The thermal management system for a fuel cell hybrid electric vehicle comprises: a galvanic pile cooling and heating loop comprising a radiator (101), a thermostat (103), a galvanic pile water pump (104), a galvanic pile (105) and a galvanic pile temperature sensor (106); a cell cooling and heating loop comprising a cell (305), a cell water pump (302), a cell temperature sensor (301) and a cell three-way valve (304), which are connected in sequence; a heating loop comprising a hydrogen combustion heater (201), a warm air core body (202), a heating loop rear-end temperature sensor (207), a heating three-way valve (203), a heating water pump (204), a heat exchanger (205) and a heating loop front-end temperature sensor (206), which are connected in sequence; and a cooling loop comprising an air conditioner (306) and a cooler (303), which are connected to each other, wherein the cooler (303) exchanges heat with the cell cooling and heating loop, both the galvanic pile cooling and heating loop and the cell cooling and heating loop are connected to the heating loop, and the cooling loop is connected to the cell cooling and heating loop. A fuel cell engine and a power cell can be warmed, the efficiency of the fuel cell engine and the power cell can be improved, and additionally, the heating economy of the air conditioner can also be improved.
