摘要： A heating apparatus for a vehicle includes a heat exchanger for implementing heat exchange between coolant which has cooled an engine and air directed to a vehicle interior to heat the vehicle interior. A viscous heater has a rotor and a heating chamber containing viscous fluid. The rotor rotates when being subjected to rotational power of the engine. The viscous fluid is subjected to a shear force and is heated when the rotor is subjected to the rotational power. The viscous heater heats the coolant fed to the heat exchanger as the viscous fluid in the heating chamber is heated. A clutch is operative for selectively permitting and inhibiting transmission of the rotational power from the engine to the rotor. A belt transmission device connects the engine and the clutch. A physical quantity detecting device is operative for detecting a physical quantity related to a rotational speed of the rotor. A control device is operative for controlling the clutch to inhibit the transmission of the rotational power from the engine to the rotor when the physical quantity detected by the physical quantity detecting device is equal to or less than a predetermined value.

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 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, 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.
摘要翻译： 根据本发明，当车速小于设定值（例如40km / h）并且节气门开度大于设定值时，确定车辆正在加速，并且粘性离合器（ 6）关闭。 因此，不执行粘性加热器（7）的转子（53）对高粘度流体的剪切操作。 以这种方式，施加于发动机的驱动负载减小，从而可以获得适合驾驶员意图的加速状态。 此外，当车速大于设定值（例如，40km / h）且发动机转速大于设定值（例如，3500rpm）时，粘性离合器（6）关闭，并且a 施加于发动机和V型皮带（4）的驱动负载降低。

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.
摘要翻译： 在发动机和前加热器芯（15）之间的冷却水回路中设置用于加热用于冷却水冷发动机（E）的冷却水的粘性加热器（9）。 即使粘性开关（73）被粘性ECU（200）接通以使用粘性加热器加热乘客舱，当发动机空转时，粘性离合器（7）也不会马上开启。 也就是说，在将发动机的怠速转速提高到目标转速之后经过延迟控制时间之后，粘性加热器被接通。 高于正常怠速转速的目标转速设定为冷却水温度越高，目标转速越低。 因此，即使在发动机怠速时通过操作粘性加热器对发动机施加较大的负荷，也能够提高燃油经济性，防止发动机熄火。

摘要： A heat recovery unit (5) in which cooling water absorbs heat generated in a water-cooled alternator (4) and a viscous heater in which cooling water absorbs heat generated in viscous fluid within a heat-generating chamber (54) have a common cooling water passage. Further, a rotor (33) of the alternator (4) and a rotor (53) of a viscous heater (6) are disposed on a shaft to have a common driving shaft (10) and a common V-belt. Therefore, cooling water pipes of a cooling water circuit are simply connected, a large space is not necessary for winding the V-belt of a belt transmitting mechanism (2), and the number of parts of a heating apparatus can be decreased. Further, because heat generated in the viscous fluid of the viscous heater (6) and heat generated with an operation of the alternator (4) are used as a supplementary heating source, a sufficient heating capacity can be provided for a passenger compartment even in a vehicle in which heat generated in the engine (E) is small.

摘要： A viscous fluid heat generator includes: a shear chamber (110) in which viscous fluid (155) is contained and heat is generated by shearing the viscous fluid with a rotor (111) rotating therein; and a space (170) receiving viscous fluid drained from the shear chamber. The heat generator is rotated always as far as an engine rotates because it is driven by the engine without a clutch. The viscous fluid in the shear chamber (110) is drained into the receiving space (170) disposed underneath the shear chamber when the rotor halts or the heat generator is not in operation. The drained viscous fluid is pushed up again into the shear chamber when the rotor is re-started or the heat generator becomes in operation again. The heat generator is re-started easily with a very small starting torque because there is almost no viscous fluid left in the shear chamber and accordingly power to shear the viscous fluid with the rotor is not required. Only a minimal power is consumed by the heat generator when heat is not required to be generated even though the rotor is continuously rotated because the viscous fluid in the shear chamber is drained in this situation.
