The present invention is provided with two evaporation parts (10, 20) disposed in series in relation to the air flow direction. Air passages (60) are formed from the spaces formed between tubes (111, 211) that are adjacent in the tube-layering direction, and inter-tube gaps (61) communicating with the air passages (60) are formed from the spaces formed between tubes (111, 211) that are adjacent in the air flow direction. The air passages (60) are provided with partition parts (80) for partitioning the air passages (60) in the longitudinal direction of the tubes, and the partition parts (80) are configured to have a pair of elastically deformable engagement pieces (81, 82) that extend in the air flow direction. Each of the pair of engagement pieces (81, 82) is provided with a protruding part (84) that is engaged with the inter-tube gap (61), and the partition parts (80) are inserted into the air passages (60) from the upstream side or the downstream side in the air flow direction. The number of components of a heat exchanger is thus reduced and the structure thereof is simplified. |
