Description

technical field [0001] The present disclosure relates to the technical field of thermal management of fuel cell vehicles, in particular to a low-power multi-coupled cooling system for fuel cell vehicles and a working method thereof. Background technique [0002] Existing heat dissipation systems perform heat exchange with the environment through radiators. Generally speaking, the two heat dissipation systems are independent, and no heat exchange is involved between the systems. The heat dissipation of the radiator can be realized by increasing the power of the fan, increasing the area of ​​the radiator and changing the arrangement position of the radiator. In addition, in traditional electric vehicles, the heater system is generally an electric heater, and there is no heat exchange between the cooling system and the heater system. [0003] During the research and development process, the inventors found that the existing cooling system has the disadvantages of complex stru...
