<P>PROBLEM TO BE SOLVED: To sufficiently exhibit performance of a heat exchanger by reducing a difference of refrigerant flow rates in respective flat pipes, the heat exchanger including flat pipes and header collecting pipes. <P>SOLUTION: In an outdoor heat exchanger 23, respective flat pipes 31, 32 are connected to a first header collecting pipe 60 at one ends, and are connected to a second header collecting pipe 70 at the other ends. The outdoor heat exchanger 23 is formed with main heat exchanging parts 51a to 51c and auxiliary heat exchange parts 52a to 52c. The second header collecting pipe 70 is formed with a plurality of partial spaces 71a to 71c, 72a to 72c. In connecting pipes 76, 77 attached to the second header collecting pipe 70, first ends 76a, 77b are connected to the partial spaces 71b, 71c corresponding to the main heat exchange parts 51a, 51b, and second ends 76b, 77b are connected to the partial spaces 72a, 72b corresponding to the auxiliary heat exchange parts 52a, 52b. The first ends 76a, 77a of the connecting pipes 76, 77 are opposed to intermediate walls 73, 74 of the adjacent flat pipes 31a, 31b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
