The invention relates to a cooling
system of a novel
hydrogen energy automobile fuel
cell stack. The cooling
system comprises a
hydrogen fuel
cell stack, a thermal management controller, a
heat sink,a
water temperature sensor, a water pump, a temperature sensor, a first compressor, an
evaporator, a second compressor, a condenser and an expansion valve, wherein the
heat sink, the water temperaturesensor and the water pump form a water-cooling circulation loop by a first pipeline, the
evaporator, the second compressor, the condenser and the expansion valve form a
refrigerant circulation loop by a third pipeline, a low-temperature condensation liquid required by the
evaporator is generated, the first compressor, the evaporator and the
hydrogen fuel
cell stack form an air-cooling circulationloop by a second pipeline, the thermal management controller is used for receiving signals of the
water temperature sensor and the temperature sensor and performing water-cooling or air-cooling
processing on the
hydrogen fuel cell stack, meanwhile, the heater on the second pipeline can be used for providing hot air for the
hydrogen fuel cell stack when the temperature is excessively low, so thatthe temperature is rapidly raised to a normal
working temperature, the
energy consumption is reduced, and the working efficiency is improved.
