ABSTRACT:
An improved heating apparatus for a vehicle is disclosed. A water circuit circulates water to cool an engine. A viscous fluid type heater is disposed in a fluid circuit that is separately arranged from the water circuit. The heater has a heating chamber and a heat exchange chamber close to the heating chamber. The heat exchange chamber communicates with the fluid circuit. The heating chamber accommodates viscous fluid and a rotor rotatable to shear the viscous fluid for producing heat. The heat is transmitted to the heat exchange chamber from the heating chamber. The fluid in the heat exchange chamber is heated and flows to the fluid circuit.
