Abstract
A centrifugal fan is provided. The centrifugal fan comprises a housing and an impeller. The housing includes an upper cover and a lower cover. The impeller is configured in the housing. The impeller includes a hub, a plurality of blades and an air guiding structure. The hub is pivoted on the lower cover and rotates around a rotation axis. The rotation axis extends in the axial direction. The blades are connected to a peripheral surface of the hub and configured between the upper cover and the lower cover. The air guiding structure is connected to the blades. An angle between the air guiding structure and the rotation axis increases along with a distance in the direction away from the hub.
