Heat Dissipating Fan

摘要

A heat dissipating fan includes a housing having a base and a sidewall coupled to the base. The sidewall defines a compartment. The housing includes an air inlet, an air outlet and a dust channel. The air outlet includes opposite first and second end edges located at a same straight side of the housing. The housing defines a first plane. The impeller includes a hub and several blades. The impeller defines a second plane. The compartment of the housing includes an air outlet section and a pressure accumulating section. The air outlet section is located between the first and second planes. The air outlet is located in the air outlet section. The dust channel extends in an angle with respect to the second plane. An impeller is coupled to the stator that is coupled to the base. A control element includes a driving circuit and a rotating direction control circuit.
