Abstract

An outdoor unit (1) of an air conditioner includes an axial flow fan (40) including a hub (41) and a plurality of blades (43) disposed on the hub (41), a rotation orifice (110) disposed to surround the axial flow fan (40), the rotation orifice (110) guiding air flowing by the axial flow fan (40), and a fixed orifice (120) having an orifice hole (121) through which the air flowing by the axial flow fan (40) passes, the fixed orifice (120) being disposed outside the rotation orifice (110). At least one portion of each of the blades (43) and one surface of the rotation orifice (110) are coupled to each other and rotated together with each other.
