Abstract (en)
Provided is a heat exchanger and an outdoor unit that prevent uneven distribution of a refrigerant to a plurality of flat pipes. In a heat exchanger including: a plurality of header pipes 52; and a plurality of flat pipes connected to each of the header pipes 52 in such a manner that the flat pipes are aligned in a longitudinal direction of the header pipes 52, at least one of the header pipes 52 serves as a coupling header pipe 54 to which a plurality of the flat pipes 62 are connected in such a manner that the flat pipes 62 are placed side by side in a direction intersecting the longitudinal direction of the header pipe 52, a side face of the coupling header pipe 54 has a connection side face 57 to which a plurality of the flat pipes 62 are connected and an opposite-side side face 59 located opposite to the connection side face 57, and the opposite-side side face 59 projects away from the connection side face toward substantially a center in the direction intersecting the longitudinal direction of the coupling header pipe 54.
