Abstract
A centrifugal fan includes a centrifugal impeller, a first housing, a second housing, an annular guide ring and a driving device. The centrifugal impeller has a hub and blades connected to and disposed around the hub. The first housing and the second housing cooperatively define a hollow chamber and an air outlet. An air inlet is formed in a central section of the second housing. A first arc structure is located on an inner surface around the air inlet of the second housing. Support brackets respectively extend from an end close to a tongue of the second housing and an end away from the tongue of the second housing. The support brackets are perpendicular to the second housing. The annular guide ring has a second arc structure close to an outermost margin of inner surfaces of the blades. The driving device is used for rotating the centrifugal impeller.
