Abstract

An outdoor cooling unit in a vehicle air-conditioning apparatus is configured such that the angle between a normal line to a suction plane of a suction portion and a normal line to a discharge plane of a discharge portion is acute and such that air inside a housing flows in a substantially checkmark-shape, substantially V shape or substantially U shape. In the outdoor cooling unit, a blade of an axial fan is configured such that a chord center line formed by connecting chord central points from an inner circumferential end to an outer circumferential end of the blade and projecting the connected chord central points on a plane containing a rotating shaft is convexly curved toward the downstream side over the entire area in the radial direction.
