| description | A heat exchanger includes: refrigerant channels that extend in a first direction, are disposed along a second direction intersecting with the first direction, and are disposed along a third direction intersecting with the first direction and the second direction; and heat transfer tubes defining the refrigerant channels. One or both of a size of an outer edge and a size of an inner edge of the heat transfer tubes are different between a first position and a second position in the first direction. Outer surfaces of the heat transfer tubes each include a protrusion that protrudes in a direction intersecting with the first direction, and is in contact with an outer surface of one of the heat transfer tubes adjacent thereto in the second direction. The protrusion includes a concave portion extending along the third direction. |
