Abstract
A centrifugal fan. The centrifugal fan has at least one air inlet and one air outlet, and at least one set of rotor blades. A sidewall extends downward from an inner margin of the air inlet to define an air-gathering chamber in the housing of the centrifugal fan for increasing airflow pressure and heat dissipating efficiency.
