<p>A heating method and apparatus for vehicles. A viscous fluid type heater (10) is located in a vehicle fluid circuit (W). The heater (10) has a heating chamber (16) that holds viscous fluid and a rotor (24). The rotor (24) rotates to shear the viscous fluid and produce heat. The heat is transmitted to a heat exchange chamber (17) located adjacent to the heating chamber (16). The rotor (24) rotates at variable rotation velocity, which affects the temperature of the viscous fluid. Circulating fluid in the fluid circuit (W) and is heated in the heat exchange chamber (17). The heater (10) includes a reservoir chamber (20) communicating with the heating chamber (16) to store viscous fluid. The heater (10) has a valve (20, 30, 30a, 37, 38, 39; 62, 64, 65) that selectively connects and disconnects the reservoir chamber (20) with the heating chamber (16) to regulate heat production. The apparatus has a detecting device (56, 57, 58) for detecting a temperature or a speed that is indicative of the temperature of the viscous fluid. The apparatus also has a controller (100) for controlling the valve (20, 30, 30a, 37, 38, 39; 62, 64, 65) to reduce heat production when the temperature of the viscous fluid is deemed to be high. <IMAGE></p> |
