摘要： PROBLEM TO BE SOLVED: To make the outdoor unit of an air conditioner compact and silent by providing a protrusion toward radial outward of a propeller fan and making a hole for introducing the air into a housing constituting the protrusion in the side wall on the upstream side of the propeller fan. SOLUTION: A protrusion 11a is provided on the wall of a housing proximate to a propeller fan 1 on the side opposite to a heat exchanger 3 toward the outside of the housing and a hole 11b for introducing the air into the housing is made in the side wall on the upstream side of the propeller fan constituting the protrusion 11a. Since the volume of air is balanced between then heat exchanger 3 side and the opposite side by the air introduction hole 11b, pressure fluctuation on the wall, face is suppressed as compared with an outdoor unit having no air introduction hole 11b. Since a protrusion is provided toward radial outside of the propeller fan, distance between the wall face of the housing and the outer edge of the fan is increased thus suppressing pressure fluctuation on the wall face furthermore.
