Abstract

See full text

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.
