Abstract
A radiation fan driving apparatus aims to allow a non-stop power supply system to output electric power to drive a radiation fan to continuously rotate at a lower speed to perform heat dissipation even the power supply device is electrically connected to an external electric power source. A control circuit and isolation protective elements are provided so that when the main power source of a computer host is ON, the power supply device delivers electric power through the main power system or the control circuit to the radiation fan to rotate at high speed to provide optimal heat dissipation effect.
Claims7
A radiation fan driving apparatus comprising:
- a radiation fan;
- a main power system;
- and
- means for delivering electric power to the radiation fan to operate continuously when an external electric power source is ON whether the main power supply is ON or OFF;
- said main power system and said means for delivering electric power connecting electrically to the external electric power source;
- the radiation fan connecting to the main power system and the means for delivering electric power.
