摘要： 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.

摘要： In a motorcar space heating system of the type having a heat pipe comprising a heat absorbing element for receiving heat from the exhaust gas of the motorcar engine and a heat discharging element for heating air flowing into a car interior space to be heated, the heat pipe is separated, at an intermediate heat exchanger installed in a working fluid passage connecting the heat absorbing and discharging elements, into a heat absorbing section and a heat discharging section. The working fluids within these two sections are therefore not intermingled with each other. A pipe extends from the intermediate heat exchanger so as to be communicative at one end thereof with the heat absorbing section. The other end of the pipe extends into a working fluid reservoir tank. When the pressure within the heat absorbing section rises as a result of increase of the quantity of heat absorbed at the heat absorbing element, the working fluid is allowed to flow through the pipe into the reservoir tank and is stored therein in liquid form. When the pressure within the heat absorbing section is reduced, the liquid working fluid in the reservoir tank flows back into the heat pipe.
