A plurality of tubes (10, 11) and corrugated fins (1) are piled up and arranged alternatively, for integrally assembled heat exchangers. The corrugated fin (1) has fin portions (1b, 1c) for the heat exchangers and a connecting portion (1a) connecting the fin portions (1b, 1c). The connecting portion (1a) is formed with slits (6, 7) arranged in first and second lines extending in a longitudinal direction (AD) of the fin (1) and at least one louver (8, 9) between the slits (6, 7) in the lines. The slits (6; 7) in the first line and the slits (7; 6) in the second line traverse a top portion (2) and a bottom portion (3) adjacent to the top portion (2) of the fin (1) and the louver (8, 9) is formed on an intermediate portion between the top portion (2) and the bottom portion (3) so that the louver (8, 9) is located between the space of the slits (6; 7) in the first line and the space of the slits (7; 6) in the second line. |
