In a heating device in which a loop-type heat pipe is disposed in which a working fluid for transmitting exhaust heat to the air is carried by an evaporator provided in a passage, and a condensing part of the heat pipe is attached to an air outlet side of a heater core for a vehicle interior. , the heat pipe includes a steam pipe disposed between the downstream of the evaporator and the upstream of the condensing section, a return pipe disposed between the downstream of the condensing section and the downstream of the evaporator, and the steam pipe disposed between the downstream of the condensing section and the downstream of the evaporator. It consists of a steam escape pipe connected between the return pipe and the return pipe, and a first pipe is located close to the steam pipe side of each of the return pipe and the steam escape pipe.
, two valve means are disposed, and a steam tank is interposed between the steam escape pipes, and the first and second valve means are such that when the heating device is turned on, the first valve means opens and the second valve means opens. is closed to form a closed loop of heat cycle, and when this heating device is OFF, the first
A heating system for a vehicle, characterized in that the valve means is closed and the second valve means is opened so that steam from the evaporator escapes to the steam tank side using a steam escape pipe.
