A cooling fan includes a fan housing, a stator mounted in the fan housing and a rotor rotatablely supported by the stator. The stator includes a stator core, an insulating frame attached to the stator core and stator coils wound on the insulating frame and around the stator core. The insulating frame electrically insulates the stator coils from the stator core. The stator core includes a main body and a plurality of claws. Every two neighboring claws define a receiving room therein. The insulating frame includes a bottom portion located at a bottom of the stator core and a plurality of flanges extending upwardly from the bottom portion into the receiving rooms of the stator core, respectively. A height of the flanges is no less than that of the stator core.

An electronic device includes a casing and a centrifugal blower. The casing includes a bottom cover and a top cover. A sidewall extends from the bottom cover towards the top cover. The centrifugal blower is surrounded by the sidewall and includes a supporting member mounted to the bottom cover, and an impeller rotatablely supported by the supporting member. The impeller includes a hub and a plurality of blades extending outwardly from the hub. Outer portions of the blades extend beyond the supporting member along a radial direction of the hub. Inner portions of the blades have a height gradually increasing along an outward direction. The outer portions have a height equal to a maximum height of the inner portions. Bottom faces of the outer portions of the blades are located below a top surface of a base plate of the supporting member.
