Detailed Description
In order to make the technical means of the present invention more clearly understood and to make the implementation of the technical means in accordance with the content of the specification, the following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings and examples, which are used for illustrating the present invention but not for limiting the scope of the present invention.

The device controls the amount of silicon oil in the working cavity 11 by closing or opening the valve plate 6, thereby realizing the stepless change of the rotating speed of the fan.
The torque transmission routes at this time are:
t input → T drive shaft → T drive plate → T casing → T fan
According to newton's third law:
t input, T drive shaft, T drive plate, T housing, T fan.
The clutch heating value:
q heat (n input-n fan) T fan/9550.
Therefore, when the clutch is in a half-coupling state, the heat productivity is the largest, and as shown in fig. 3, the silicone oil is easily deteriorated and loses the torque conduction capability because the temperature of the clutch is too high, so that the coupling capability of the clutch is lost, and the engine is high in temperature.
And the effective work efficiency at this time:
n fan/n input
Most of the power transmitted to the fan by the engine is invalid power because the clutch fan is in a separation state or a half-coupling state when in work, so that power waste is caused, and the oil consumption is increased.

Therefore, there is a difference in the rotational speed between the coil winding 9 and the permanent magnet 8, and the power for generating the alternating current is P current, and the torque acting between the coil winding 9 and the permanent magnet 8 is T current, with reference to the generator principle.
The torque transmission routes at this time are:
according to newton's third law, at this time:
t input-T fan-T active board + T power.
The clutch heating value:
q heat (n input-n fan) T motherboard/9550.
Assuming that the heat dissipation requirement is constant, i.e. the fan speed is constant, the fan torque T is constant according to the fan characteristics, i.e.:
t active board ═ T fan-T electricity
Obtaining the following formula:
q heat ═ (n input-n fan) (T fan-T power)/9550
N input T fan-n fan T fan- (n input-n fan) T power
P input-P fan-P electricity
