PURPOSE:To improve the heating efficiency and to expand the temperature controlling scope, by providing a combustor and a heat exchanger of a combustion-type heating unit at the outside of a car room, while providing a collecting hole to take in room air in the car room and warm air blowoff holes at the side wall of the car respectively, in a vehicle laden with an internal combustion engine. CONSTITUTION:A combustor 1, a heat exchanger 2, and a blower 7, of a combustion-type heating unit are provided at the outside of a car room 4, and the air in the car room 4 is taken in through an air collecting hole 5 and an air circulating passage 7 provided at the front side of the car room 4. the taken-in room air is heat-exchanged to be heated at the heat exchanger 2 to which a burnt gas of the combustor 1 has been invited. The room air is delivered to a blowing unit 8 provided at the side wall of the car through a blast pipe 9, and blown off from warm air blowoff holes 12. In such a composition, the heating capacity is improved, and the temperature can be controlled in a wide area including the car room and the cargo house. |
