<P>PROBLEM TO BE SOLVED: To provide a fin tube type heat exchanger which can be manufactured with a high yield while securing the long length of a fin edge. <P>SOLUTION: A heat exchanger viewed from one flank is subjected to wind supply in the Y direction and is equipped with heat transfer fins 3 which are arrayed in the X direction orthogonal to the Y direction and a plurality of heat transfer tubes 2 which pierce the heat transfer fins 3. Each heat transfer fin 3 has a wave form where linear crests 31 and troughs 32 inclining relative to the Y direction are formed alternately. The edges 30 on both sides in the Y direction of each heat transfer fin 3 zigzag to be orthogonal to the crests 31 and troughs 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
