<P>PROBLEM TO BE SOLVED: To enable suppressing the warp itself produced by the push-opening of opening sides of notches by flat heat transfer tubes. <P>SOLUTION: A heat exchanger includes: flat heat transfer tubes 1 through which a working fluid passes thereinside; and fins 2 on which notches 2a are juxtaposed like a comb teeth in a longitudinal direction, wherein the fins 2 are laminated plurally with gaps, and the flat transfer tubes 1 are impacted in the notches 2a. Furthermore, the depths of the notches 2a at both end sides are deeper than those of central parts of the fins in the longitudinal direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
