An upper heat exchange region (51) is divided into a plurality of main heat exchange parts (51a-51c), and a lower heat exchange region (52) is divided into a plurality of auxiliary heat exchange parts (52a-52c). A first header collecting pipe (60) is divided into an upper space (61) corresponding to the upper heat exchange region (51) and a lower space (62) corresponding to the lower heat exchange region (52). The lower space (62) is divided into a plurality of communication spaces (62a-62c) corresponding respectively to the auxiliary heat exchange parts (52a-52c). A second header collecting pipe (70) is divided into a communication space (71c) corresponding to both of the lowermost main heat exchange part (51a) of the upper heat exchange region (51) and the uppermost auxiliary heat exchange part (52c) of the lower heat exchange region (52), and into communication spaces (71 a, 71b, 71d, 71e) corresponding respectively to the other main heat exchange parts (51b, 51c) and the other auxiliary heat exchange parts (52a, 52b). Each of pairs of communication space (71 a, 71b) and communication space (71d, 71e) is connected to an associated one of communication pipes (72, 73). |
