<P>PROBLEM TO BE SOLVED: To provide a storage type heat exchanger preventing the generation of gap corrosion and boiling sound. <P>SOLUTION: The storage type heat exchanger has a hot water can body 27 comprising an outer can 28 and an inner can 29 storing hot water and a burner part 26 in the bottom part of the hot water can bottle 27 such that the hollow part of the center of the hot water can body 27 is a combustion chamber 30 and has an inner can ring 31 continuously connected to the inner can 29 in the lower end of the hot water can body 27 and a part in which hot air of the burner part 26 acts and a partitioning plate 34 in which a step part 33 is formed by making an upper part overhang to the burner part 26 in the lower part of the inner can ring 31 and further has a first heat insulation material 35 and a second heat insulation material 36 blocking the hot air from the burner part 26 in an upper and lower parts of the step part 33 of the partitioning plate 34, a ring-shape third heat insulation material 37 is arranged in the burner part 26 side of the first and second heat insulation materials 35, 36, thereby the gap corrosion and the boiling sound can be surely prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
