Abstract
A heat exchanger includes: a plurality of flat tubes that each have a cross-sectional shape perpendicular to a direction of flow of refrigerant with a width direction that extends in an air flow direction; and a plurality of heat transfer fins each having a plurality of notches that receive the plurality of flat tubes. The plurality of notches is disposed along the width direction. The plurality of heat transfer fins includes at least three stands, disposed on a periphery of each of the plurality of notches, that form gaps between adjacent heat transfer fins. The at least three stands are disposed to not face each other across a reference line that extends in the width direction through a perpendicular center of each of the plurality of flat tubes.
