Abstract
In a heat exchanger, each of a plurality of heat exchange members includes: a flat pipe; and a heat transfer plate integrated with the flat pipe along a longitudinal direction of the flat pipe. A width direction of each of the flat pipes intersects with a direction in which the plurality of heat exchange members are arranged side by side. Each of the heat transfer plates includes an extending portion extending outward in the width direction of each of the flat pipes from at least one of one end of a corresponding one of the flat pipes in the width direction and another end of the corresponding one of the flat pipes in the width direction. Each of the flat pipes has one or more flat pipe bent portions, each forming a groove extending along the longitudinal direction of the flat pipes.
