Abstract:
1. A fan voltage regulation control device for stabilizing voltage and determining a rotation speed of a heat-dispersing fan, comprising: an input power source, which can provide an input voltage; a heat-dispersing fan; a voltage regulation control unit, which is electrically connected between the input power source and the heat-dispersing fan for receiving a rotation speed parameter and a reference voltage, and which comprises a voltage regulation element for converting the input power into a stable output voltage to the heat-dispersing fan so as to stabilize the rotation speed of the fan; a temperature detecting element directly electrically connected to the voltage regulation control unit for providing a rotation speed parameter, which is an environmental temperature coefficient; and a voltage detecting unit connected to the voltage regulation control unit for providing a reference voltage to the voltage regulation control unit.
