Abstract
A fan includes a fan frame, a stator fixedly mounted in the fan frame, and a rotor fixedly mounted in the fan frame. The rotor includes an impeller. The impeller includes a main body and a number of blades equally spaced around a periphery of the main body. The main body includes a top portion and a side portion. The top portion has an annular shape. The side portion has a cylindrical shape and extends from a peripheral edge of the top portion. A number of heat dissipating portions protrudes from an inner side of the top portion. The heat dissipating portions are arranged at intervals.
