PROBLEM TO BE SOLVED: To suppress increase of pressure loss when a refrigerant flows in each refrigerant flow channel and to easily perform bending processing in a width direction of a flat tube, in a heat exchanger provided with a plurality of refrigerant flow channels inside of the flat tubes.SOLUTION: A plurality of row portions (30, 40) having a plurality of flat tubes (31, 41) are arranged in an air passing direction, the plurality of row portions (30, 40) are configured so that a refrigerant flows in parallel in each of the flat tubes (31, 41) respectively between the plurality of row portions (30, 40), and the flat tubes (31, 41) of the plurality of row portions (30, 40) respectively have one or more bent portions (33a, 33b, 33c) bent in a width direction of the flat tubes (31, 41) so that the flat tubes (31, 41) of the row portions (30, 40) adjacent to each other in the air passing direction, are along to each other.SELECTED DRAWING: Figure 2 |
