PURPOSE:To realize a safe and efficient heating, by blowing off the warm air of a combustion-type heating unit from blowoff holes with shutters provided at the side wall, and taking in the room air from the front side of the car room, in a heating device of a vehicle laden with an internal combustion engine. CONSTITUTION:The air in a car room 4 is delivered to a heat exchanger 2 through an air collecting hole 5 and an air circulating passage 17. Since the burnt gas of a combustor 1 is invited to the heat exchanger 2, the taken-in room air is heated there. The heated warm air is delivered to an air flow passage 8, and blown off through warm air blowoff holes 12 to the car room 4. In this case, sutters 20 are controlled as required to control the warm air can be blown off to the selected portions, and the warming of the car room and the cargo room can be carried out efficiently. |
