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, in a heating apparatus (1) having a viscous heater (9) using viscous fluid for heating cooling water, when an engine rotational speed is lower than a set rotational speed relative to a temperature of viscous fluid, a viscous clutch (7) is turned on to transmit a rotational driving force of the engine to a rotor (53) of the viscous heater. In this way, a shearing force is applied to the viscous fluid in the heat-generating chamber (50), and the circulating cooling water is heated by generated heat of the viscous fluid to improve the heating capacity. When the engine rotational speed is higher than the set rotational speed relative to a temperature of viscous fluid, the viscous clutch is not turned on. Therefore, the rotational driving force of the engine is not transmitted to the rotor of the viscous heater, so that the shearing force is not applied to the viscous fluid to prevent the oil temperature of the viscous fluid from increasing excessively higher than 200 DEG C.

摘要： A viscous heater (9) for heating cooling water for cooling a water cooled engine (E) is provided in a cooling water circuit between the engine and a front heater core (15). Even if a viscous switch (73) is turned on by a viscous ECU (200) to heat a passenger compartment using the viscous heater, a viscous clutch (7) is not immediately turned on when the engine is idling. That is, after a delay control time elapses after increasing an idling rotational speed of the engine to a target rotational speed, the viscous heater is turned on. The target rotational speed which is higher than a normal idling rotational speed is set in such a manner that the higher the cooling water temperature is, the lower the target rotational speed becomes. Thus, even if a large load is applied to the engine by operating the viscous heater when the engine is idling, it can improve fuel economy and prevent an engine stall.

摘要： According to the present invention, when a vehicle speed is less than a set value (e.g., 40 km/h) and a throttle opening degree is more than a set value, it is determined that the vehicle is accelerating, and a viscous clutch (6) is turned off. Therefore, a shearing operation of high-viscosity fluid by a rotor (53) of a viscous heater (7) is not performed. In this way, a driving load applied to an engine is reduced, so that an accelerating state suitable for an intention of a driver can be obtained. Further, when the vehicle speed is more than a set value (e.g., 40 km/h) and an engine rotational speed is more than a set value (e.g., 3500 r.p.m.), the viscous clutch (6) is turned off, and a driving load applied to the engine and a V-belt (4) is reduced.

摘要： According to the present invention, when an air-conditioning clutch (27) of a compressor is set on, even if an improvement of a heating capacity by a viscous heater (4) is required, a viscous clutch (7) is turned off not to transmit a rotational driving force of an engine (E) to a rotor (53) of the viscous heater, and further the rotational driving force of the engine is transmitted to the compressor. In this way, a torque applied to the engine E and a V-belt (6) can be reduced, so that a fuel consumption ratio of the engine lowers and a fuel economical performance improves. Further, because an operation of the compressor is intermitted, it is possible to remove a fog of a front windshield, so that a safety of the vehicle travelling can be prevented from being deteriorated.

摘要： An air conditioning apparatus preferentially ventilates a space close to a seat and/or a steering wheel on which a passenger directly makes a contact in a passenger compartment while a vehicle is parked. The uncomfortable feeling of a passenger that might occur when he/she is getting into the parked vehicle can be reduced using a small capacity in the air conditioning as compared to the air conditioning apparatus ventilating the whole space in the vehicle.
