両用暖房装置。[Scope of Claim for Utility Model Registration] A cooling water passage for circulating cooling water is provided between the engine and the cabin heater, and a blower fan is provided to supply air for heat exchange with the cooling water circulating through the heater core. 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. A liquid tank is disposed in a second pipe of the heat pipe that communicates downstream of the condensing section, and a third pipe having an opening near the bottom of the liquid tank communicates with the first pipe. , a fourth pipe having an opening on a side surface of the liquid tank at a higher position than the opening of the third pipe is communicated with the first pipe, first and second valve means are interposed between the third and fourth pipes, The opening and closing of the first and second valve means are controlled by a control device, and the control device controls opening and closing of the first valve means to return the working fluid to the evaporator, and also controls the opening and closing of the first valve means in accordance with conditions such as exhaust temperature and steam temperature. The first valve means is closed and the second valve means is opened so that only the minimum amount of working fluid required remains in the pipe, so that it takes time for the working fluid to reach the opening of the fourth pipe. A vehicle heating device characterized by:
