PURPOSE:To heat the air efficiently and to heat the car room in good stirring up by evaporating a liquid coolant with the heat of an engine, and after that, heat-exchanging with the air and feeding the heat-exchanged and heated air to the car room. CONSTITUTION:A vapor generator 20 to evaporate a liquid coolant is attached to an engine 10, a heater core 50 to be a heat-exchanger with the air is provided in a duct case 40, and they are connected with a leading pipe 30. The heater core 50 is connected to a coolant tank 70 to be a storage device through a return pipe 60. Furthermore, a pump 90 to be a coolant delivery means is attached to the coolant tank 70, and the liquid coolant is led in to the vapor generator 20 through a leading-in pipe 100. On the other hand, an evaporator 120 and a blower 130 to deliver the air are provided in the duct case 40. As a result, the coolant evaporated in the vapor generator 20 is heat-exchanged with the air at the heater core 50, and the air is heated efficiently. |
