摘要： An outdoor unit for an air-conditioning apparatus includes a heat exchanger including a plurality of heat exchanger units. The plurality of heat exchanger units are vertically stacked and each include a long side portion, a short side portion, and a corner portion bent and connecting the long side portion and the short side portion to each other. In the heat exchanger, deviation in an air flow direction that lies between ones of the plurality of heat exchanger units that are vertically adjacent to each other is larger at the short side portions than at the long side portions.

摘要： A heat exchanger, a heat exchanger unit, and a refrigeration cycle apparatus are provided where deterioration in drainage and ventilation properties is prevented, an air passage is not easily clogged when frost forms, and both defrosting properties and heat exchange performance are achieved. A flat tube and a plurality of fins that are each a plate having a plate surface extending in a longitudinal direction and in a width direction orthogonal to the longitudinal direction are provided. The plate surface intersects a pipe axis of the flat tube. The plurality of fins each have an insertion portion in which the flat tube is inserted, a first spacer formed at a rim of the insertion portion and maintaining the interval, and a second spacer formed at a portion of the plate other than the rim of the insertion portion and maintaining the interval.

摘要： A heat exchanger, a heat exchanger unit, and a refrigeration cycle apparatus are provided where heat exchange performance is improved, and drainage properties and resistance against frost formation are improved. A flat tube and a plurality of fins that are each a plate having a plate surface extending in a longitudinal direction and in a width direction orthogonal to the longitudinal direction are provided. The plate surface intersects a pipe axis of the flat tube, and the plurality of fins are arranged at an interval from one another. The plurality of fins each have a first spacer formed in the plate and maintaining the interval. The flat tube has a longitudinal axis of a section perpendicular to the pipe axis, and the longitudinal axis is inclined to the width direction by an inclination angle θ. The first spacer has a standing surface extending in a direction intersecting the plate surface.

摘要： An air-conditioning outdoor unit includes a compressor having a plurality of terminals each including a plurality of conductive pins. The outdoor unit includes a plurality of lead wire groups provided for the respective terminals and each including a plurality of lead wires connecting a control board to the plurality of conductive pins, and a plurality of different end connectors provided for the respective lead wire groups and each attached to an end portion of the lead wire group adjacent to the plurality of conductive pins. The lead wire groups are each connected by the end connector to the plurality of conductive pins and cut into two parts at a given point in a longitudinal direction. The two parts of the lead wire group are detachably coupled together at the given point by a pair of relay connectors. A length from the control board to the given point and a length from the given point to the end connector differ from one lead wire group to another.

摘要： In an axial flow fan according to the present invention, a plurality of blades rotate about a rotation axis of the blades to convey a fluid. In the axial flow fan, the plurality of blades each have a leading edge at a leading side in a rotational direction, a trailing edge at a trailing side in the rotational direction, and an outer peripheral edge connecting the leading edge and the trailing edge. The leading edge of one of the plurality of blades and the trailing edge of another blade adjacent to the leading edge of the blade in the rotational direction are connected by a plate-shaped connection portion. The plurality of blades each have at least one plate-shaped reinforcement rib extending from a periphery of the rotation axis toward the outer peripheral edge of the blade.
