Abstract
A heat exchanger has: a heat transfer tube group made up of plural heat transfer tubes each of which has, inside the heat transfer tube, a flow passage through which refrigerant flows; a fin provided on the heat transfer tubes; and a bridging header into which end portions of the heat transfer tubes are inserted and that causes refrigerant to flow between the heat transfer tubes. The bridging header has a base having a flat plate shape. The bridging header also has a corrugated sheet forming, between the corrugated sheet and the base, a header flow passage, through which refrigerant flows. The bridging header also has a covering plate covering the corrugated sheet and pressing the corrugated sheet toward the base.
