Abstract:
To provide a vehicular air conditioning system which includes a heat pipe system to improve heating capacity and enables the heat pipe system to start smoothly.SOLUTION: A vehicular air conditioning system includes a heat pipe system. A liquid pipe of the heat pipe system is a path for returning a working medium liquefied by a condenser to an evaporator 16 and has an upstream part 21a and a downstream part 21b. A check valve 23 is inserted between the upstream part 21a and the downstream part 21b of the liquid pipe. The check valve 23 has a flap 233 which may rotate in a space 231a in a case 231. The check valve 23 inhibits the working medium in a gas phase from flowing reversely to the upstream part 21a with the flap 233 closed when the working medium in the gas phase enters from the downstream part 21b.SELECTED DRAWING: Figure 6
