Disclosed herein is an outdoor unit for an air conditioner including a blowing apparatus for reducing suction loss of a propeller fan generated in corners of a housing and achieving high efficiency of blowing and low noise. The blowing apparatus includes a housing including a wall in which an outlet is formed, a propeller fan positioned in the inside of the housing, the propeller fan facing the outlet, and a diffuser positioned at a discharging side of the propeller fan, and forming the outlet, wherein the diffuser includes an inclined surface inclined with respect to a rotation axis of the propeller fan, and an inclination angle of the inclined surface to the rotation axis of the propeller fan changes according to a circumferential direction of the diffuser.

An outdoor unit of an air-conditioning apparatus includes a heat exchange body including a plurality of flat tubes that extend in a vertical direction and that are arranged in a horizontal direction with gaps therebetween. A plurality of the heat exchange bodies are arranged in a direction of air flow to form a heat exchanger. A first header, into which hot gas refrigerant flows from a refrigerant circuit, is provided below one of the plurality of the heat exchange bodies that is at a most upwind position.

Disclosed herein is a blower blowing air and an outdoor unit of air conditioner having the same. The blower includes a fan, a motor driving the fan, and a motor support member disposed on a flow path, through which air generated by a rotation of the fan flows, to support the motor. The motor support member includes a cross-sectional shape including a maximum width portion having a maximum width in a direction perpendicular to the airflow direction, an upstream portion having a width being increased from the upstream side to the downstream side, and a downstream portion having a width being reduced from the upstream side to the downstream side. A downstream end located downstream of the downstream portion has a width in a direction perpendicular to the airflow direction.
