  • Temperature controlled radiating fan
    Patent number: 6291956
    Abstract: A temperature controlled radiating fan comprises a temperature detector, a control circuit, a power control circuit, a regulator, a loading circuit, and a driving circuit. The temperature detector is connected to the control circuit. The output of the control circuit is connected to the power control circuit. The output of the power control circuit is connected to the loading circuit. The output of the loading circuit is connected to the driving circuit. The power control circuit is connected to the regulator. Thereby, the rotary speed of the fan motor is varied according to a voltage variation, so that the characteristic of the rotary speed of the fan motor is linearly changed.
