Abstract

A cooling fan includes a base, a tube, a bearing, a stator, a rotor, and fan blades. The base includes a base protrusion. Each of the fan blades includes a first notch. When the cooling fan is working, the base protrusion passes through the first notch on each of the fan blades. The base protrusion and the first notch not only increase the heat exchange area of the base but break the thermal boundary layer on the base repeatedly to improve the heat dissipating effect when the cooling fan is working.
