Abstract: A cooling fan includes a frame base including a frame wall, a bottom plate and a cover plate for enclosing and defining a containing space. The vane wheel is installed in the containing space and provided for producing a cooling forced airflow when the vane wheel is in a forward rotation status and forming a strong wind area, and producing a dust discharging forced airflow when the vane wheel is in a reverse rotation status. The moving baffle module is rotably installed in the strong wind area, and the frame base includes a dust discharging opening configured to be corresponsive to the periphery of the strong wind area, and the dust discharging forced airflow is affected by the moving baffle module to discharge dust from the dust discharging opening to the outside.
