Abstract
A centrifugal fan that sends out in a radial direction a fluid sucked from an axial direction, includes an impeller rotatable about a center axis extending in a top-bottom direction, and a motor that rotates the impeller. The motor includes a rotor rotatable about the center axis, and a stator that faces at least a portion of the rotor in the radial direction. The impeller includes an impeller hub fixed to the rotor, centrifugal vanes disposed in a circumferential direction on a radial-direction outer side of the impeller hub, and axial flow vanes disposed in the circumferential direction on a radial-direction inner side of the impeller hub. The axial flow vanes are disposed on an axial-direction upper side of the stator.
