ABSTRACT:
A heat pipe provided with a vaporizable working fluid is utilized to transfer heat from exhaust gas flowing through the exhaust pipe of an engine driving a vehicle to air flowing through an air duct to an interior space to be heated in the vehicle. The heat pipe has a loop return pipe for returning condensed fluid to a heat absorption part of the heat pipe and a control valve in the return pipe for controlling the flow of returning fluid, the control valve being controllable manually or automatically by a temperature control system including a sensor in the air duct, a control circuit, and a solenoid valve actuator.
