Abstract (en)
Provided are an axial flow fan (20) and an air conditioner outdoor unit (100) including the axial flow fan (20). The axial flow fan (20) includes a hub (21) and blades (23) disposed on an outer surface of the hub (21). Each of the blades (23) satisfies that a shortest distance (R L 2) measured from an imaginary line (L2) passing through a center of the hub to a front end of an outer edge of the blade (23) is greater than a shortest distance (R T 2) measured from the imaginary line (L2) to a rear end of the outer edge of the blade (23). The front end of the outer edge of the blade ( 23) is a leading end (24) in a rotation direction of the blade (23), and the rear end of the outer edge of the blade is a trailing end (25) in the rotation direction of the blade. Owing to the shape of the blade (23), noise can be reduced while increasing the flowrate of air.
