Abstract
A dissipation device includes a dissipation fin set and a centrifugal fan. The centrifugal fan outputs airflow toward the dissipation fin set to remove the heat from it. The centrifugal fan includes a centrifugal impeller mounted on a motor. An outer housing houses the motor and the centrifugal impeller therein. An inner wall of the housing's outlet has feathered structure to reduce noises. The dissipation fin set includes a fin structure adjacent to a heat source, as well as an airflow channel housing. The airflow channel includes featured structures for reducing noises.
