HYDROGEN TANK COOLING DEVICE AND COOLING METHOD IN HYDROGEN FUEL AUTOMOBILE, AND HYDROGEN FUEL AUTOMOBILE

摘要

A hydrogen fuel automobile having a heating medium flow path capable of exchanging heat with a drive section and feeding a heating medium to a heating medium pipe of a hydrogen tank. A cooler has a compressor for compressing refrigerant gas, a condenser, an evaporator, and a refrigerant circulation circuit. The hydrogen fuel automobile has a bypass flow path branched from the refrigerant circulation circuit, and the bypass flow path allows expanded refrigerant liquid to bypass the evaporator and be sucked into the compressor. A switching section can be switched between a state where the refrigerant liquid is sucked into the compressor through the evaporator and a state where the refrigerant liquid flows through the bypass flow path while detouring the evaporator. A hydrogen occlusion material cooling section cools a hydrogen occlusion material in the hydrogen tank by using the refrigerant liquid flowing through the bypass flow path. Consequently, hydrogen filling time can be reduced as compared with a case where the hydrogen tank is cooled by using a vehicle mounted radiator and fan.
