摘要： A viscous fluid type heat generator which includes a housing assembly defining a heat generating chamber (5) and a heat receiving chamber (13,14) arranged adjacent to the heat generating chamber via a partition wall (2,3) disposed therebetween. A rotor element (11) is mounted to be rotated by a drive shaft (8) for rotation within the heat generating chamber (5). A viscous fluid is held in a gap defined between the inner wall surfaces of the heat generating chamber (5) and the outer faces of the rotor element (11), for heat generation under shearing stress applied by the rotation of the rotor element (11). A heat exchanging fluid circulates through the heat receiving chamber (13,14) to receive heat transferred through the partition wall from the heat generating chamber. A plurality of grooves (23a,23b) are formed on at least one of the inner wall surfaces of the heat generating chamber (13,14) to increase a total heat transfer surface area in the inner wall surfaces, and thus to enhance a heat transfer efficiency through the partition wall. The density of arrangement of the grooves (23a,23b) in the outer peripheral area of the inner wall surface is larger than that in the inner peripheral area of the latter.

摘要： According to the present invention, an oil storage chamber (49) for temporarily accumulating a high-viscosity oil is formed below a heat-generating chamber (48) for accumulating high-viscosity oil which generates heat when a shearing force is applied thereto. When an electromagnetic coil (31) of an electromagnetic clutch (4) is set off, i.e., a rotation of a rotor (9) of a viscous heater (5) is stopped, the high-viscosity oil in the heat-generating chamber moves into the oil storage chamber by own weight thereof, and a liquid level of the high-viscosity oil in the heat-generating chamber is greatly reduced. In this way, when the electromagnetic coil of the electromagnetic clutch is turned on to start the rotor of the viscous heater, a torque applied to the rotor is greatly reduced, with the result that a stress applied to the rotor is reduced.

摘要： A viscous heater (9) for heating cooling water for cooling a water cooled engine (E) is disposed in a cooling water circuit (W), and a front heater core (15) is disposed in the cooling water circuit at a downstream side of the viscous heater with reference to a flow direction of the cooling water. Only when a heating operation is the maximum heating operation or the maximum heating operation is desired, a viscous clutch (7) is turned on to transmit a driving force of the engine to the viscous heater. When the maximum heating operation is not desired, the viscous clutch is turned off so that the driving force of the engine is not transmitted to the viscous heater. Therefore, a load of the engine is reduced, and the cost for running the vehicle can be lowered.
