Centrifugal fan - Wikipedia

A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower fan, biscuit blower [citation needed], or squirrel-cage fan (because it looks like a hamster wheel).
