<P>PROBLEM TO BE SOLVED: To improve discharging performance of condensed water, to improve heat exchanging efficiency, to prevent blockage of a combustion gas flow channel and corrosion of flat tubes and the like, and to make a heat exchanger compact. <P>SOLUTION: In this heat exchanger 6 for recovering latent heat, heating the fluid circulated inside of the flat tubes 10 vertically stacked while keeping approximately horizontal attitude, by recovering latent heat from a gas circulated in the direction intersecting with the fluid circulating direction and the approximately horizontal direction at the external of the flat tubes 10, a corrugated fin 14 is disposed around the flat tubes 10 along the gas circulating direction, and a condensed water discharge opening 15 is formed at an end portion of the corrugate fin at a downstream side of the gas. <P>COPYRIGHT: (C)2007,JPO&INPIT |
