Abstract

An outdoor unit for an air conditioner has an axial-flow fan and a bell mouth. The axial-flow fan is constructed by arranging blades at predetermined intervals along the outer periphery of a hub, each of the blades being formed such that the outline of its rear edge relative to the rotational direction is recessed toward its front edge. The bell mouth is provided on the side of air blow by the axial-flow fan. An axial-flow blower is provided in the outdoor unit. The bell mouth and the axial-flow fan are arranged in the axial-flow blower such that a ratio X/L is in the range of 0.2-0.8 with X being the distance between that portion of the blade’s rear edge outline that is most deeply inwardly recessed in the rotating direction and an air outflow surface of the bell mouth, L being the axial length of bell mouth.
