Abstract
A heat exchanger includes a plurality of flat heat transfer tubes and a header, wherein the header includes an inflow plate that divides an interior portion of the header into an inflow portion and a circulation portion located on an upper side of the inflow portion, a first partition member that divides the circulation portion into an ascending path to which the flat heat transfer tubes are connected and a descending path, that forms an upper communication path that connects the ascending path and the descending path on an upper side of the circulation portion, and a lower communication path that connects the ascending path and the descending path on a lower side of the circulation portion, and the inflow plate includes a first ejection hole that ejects, on the ascending path side and a downwind side, a refrigerant from the inflow portion to the ascending path.
