摘要:
An outdoor cooling unit (100) in a vehicle air-conditioning apparatus is configured such that the angle between a normal line to a suction plane of a suction portion (12) and a normal line to a discharge plane of a discharge portion (13) is acute and such that air inside a housing (10) flows in a substantially checkmark-shape, substantially V shape or substantially U shape. In the outdoor cooling unit (100), a blade (22) of an axial fan (2) is configured such that a chord center line (226) formed by connecting chord central points (225) from an inner circumferential end (223) to an outer circumferential end (224) of the blade (22) 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.
