る自動車の排気熱利用式暖房装置。 An electric actuator in which an engine exhaust pipe is configured with a branched exhaust pipe that passes through an exhaust heat exchanger and a bypass exhaust pipe that bypasses the exhaust heat exchanger, a switching valve is provided at the branched part, and the switching valve is switched and operated. When the heater cock is opened with the switching valve opening the exhaust pipe passing through the exhaust heat exchanger, the cooling water after cooling the engine is heated by the exhaust heat while flowing through the exhaust heat exchanger. After reaching the rear heater core, the heat is radiated and heated, and then the cooling water flows back into the engine.With the heating circulation circuit and the switching valve opening the exhaust pipe passing through the exhaust heat exchanger, the above-mentioned heater core is opened. a circulation circuit for promoting engine warm-up of the cooling water through which the cooling water after cooling the engine is heated by exhaust heat in the exhaust heat exchanger and then flows into the engine again when the electric actuator is closed; A low-temperature switch that operates when the engine is warmed up, a high-temperature switch that operates when the engine coolant reaches a high temperature, a heater cock switch that operates on and off based on the opening and closing of the heater cock, and a heater blower operation control. In an automotive exhaust heat heating system that is controlled by a blower switch, the pressure sensor detects the pressure inside the intake pipe of the engine intake system and activates when the pressure exceeds a set value. A heating device using exhaust heat for a vehicle, comprising a control circuit that issues a signal to the electric actuator to switch and maintain the switching valve in the bypass exhaust pipe open state.
