Abstract
An axial-flow type fan includes a fan housing consisting of an air inlet, an air outlet and an air channel, and a fan wheel consisting of a hub and fan blades. The air channel of the fan housing accommodates the fan wheel which has end-cornered cutting blades proximate the air outlet of the fan housing. When the fan wheel is rotated, the end-cornered cutting blades are able to eliminate air turbulence and air noise in the air outlet of the fan housing.
