<P>PROBLEM TO BE SOLVED: To provide a latent heat recovery heat exchanger with an evaporation sound preventing means having simple construction advantageous in manufacturing cost and space formation, and to provide a hot water supply device adopting the same. <P>SOLUTION: The latent heat recovery heat exchanger 1 for the hot water supply device comprises a storage case, a water pipe group stored in the storage case, a water inlet side header portion and a water inlet 4a, a hot water outlet side header portion and a hot water outlet 5a, a combustion gas inlet 10, and a combustion gas outlet 11. For preventing the generation of drain evaporation sounds, a radiating part 13 with a radiating coat layer 13a is provided in at least part of a portion of the bottom wall of the storage case where drain drops from water pipes. The radiating coat layer 13a is formed of a special radiating coat. <P>COPYRIGHT: (C)2007,JPO&INPIT |
