<P>PROBLEM TO BE SOLVED: To inexpensively provide a latent heat exchanger in which a heat-absorbing tube is stably fixed in a casing. <P>SOLUTION: An upper protrusion 144 and a lower protrusion 131, both protruding into the inside of the casing 2, are formed in a top plate 40 and a bottom wall 13, respectively, when a casing body 10 and the top plate 40 are joined. A plurality of heat-absorbing tubes 50 are overlapped with each other, at flatly-machined arc-like folding-back parts 52, and the upper and lower protrusions 144 and 131 are brought into contact with the uppermost and lowermost arc-like folding-back parts 52, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
