OUTDOOR UNIT AND REFRIGERATION CYCLE APPARATUS INCLUDING THE OUTDOOR UNIT

摘要

An outdoor unit according to the present invention includes an air-sending-device chamber including a heat exchanger disposed at least on the rear side within an outdoor unit body, a propeller fan having a plurality of blades and disposed on the front side of the heat exchanger, and a bell mouth disposed on the front side of the propeller fan to face an air outlet, a machine chamber in which a compressor is disposed, and a partition plate that separates the air-sending-device chamber and the machine chamber. The partition plate has a protruding shape protruding from the air-sending-device chamber toward the machine chamber. The partition plate has, on the side of the air-sending-device chamber, a recessed area corresponding to the protruding shape. The amount of recess of the recessed area is maximized at a position equal in height to the center of rotation of the propeller fan.
