Abstract

Disclosed is a axial flow fan of an outdoor unit of an air conditioner. The axial flow fan comprises a hub connected with a rotational shaft of a motor; and at least one blade contacting the hub, wherein the blade has a part from the hub to a predetermined portion of the blade among a whole part from the hub to an outer end of the blade, and t he other part from the predetermined portion of the blade to the outer end of the blade, t he part being equally applied at a predetermined rake angle, and the other part being rais ed in a direction of a pressure surface of the blade, and wherein a ratio of an inner diam eter and an outer diameter of the axial flow fan is between about 0.35 and about 0.4.
