when the fan runs at a low speed, the first coil is electrified, the electromagnetic force generated by the first coil counteracts the magnetic force of the permanent magnet, and the first electromagnetic clutch device is in a disconnected state, so that the fan runs at a low speed;
when the reversing working condition is adopted, the first coil is electrified, the electromagnetic force generated by the first coil counteracts the magnetic force of the permanent magnet, the first electromagnetic clutch device is in a disconnected state, then the second coil is electrified, the second electromagnetic clutch device is in a combined state under the action of the electromagnetic force generated by the second coil, and the power transmission of the fan along with the driving wheel of the engine, the second driving wheel, the second driven wheel and the first driven wheel is realized, so that the rotating direction of the fan is changed.
