OUTDOOR COOLING UNIT FOR AIR CONDITIONING DEVICE FOR VEHICLE

摘要

An outdoor cooling unit for vehicular air conditioning apparatus includes: a casing (1) including an outlet section (12), inlet sections 13) formed on one of both sides of the outlet section to have an inlet plane inclined; a first heat exchanger disposed to face one of the inlet sections and a second heat exchanger disposed to face an other of the inlet sections; at least one propeller fan (3) disposed below the outlet section (12) to blow out air upwardly. An angle formed between the normal line to the inlet plane and the z axis is an acute angle. Each of the blades is defined by a blade chord center point on an inner peripheral end thereof and an other blade chord center point on an outer peripheral end thereof, positioned so that a line segment (327) connecting therebetween has an inclination to the outlet section (12) proportionally to closeness to outer periphery of the blade. A blade chord center line (326) connecting the blade chord center points from the inner peripheral end of the blade to the outer peripheral end of the blade forms a curve being convex toward the outlet section (12) across the entire area.
