<P>PROBLEM TO BE SOLVED: To miniaturize a liquid-liquid heat exchanger and to reduce its cost, in the liquid-liquid heat exchanger comprising a first flow channel where a heat medium heated by the heat exchanger applying a burner mounted on a heat source machine as its heat source flows, and a second flow channel where heated liquid flows, and heating the heated liquid by the heat medium. <P>SOLUTION: Three sheets of press-formed plates composed of first and second outer plates 71, 72 and an intermediate plate 73 held between the outer plates are overlapped. The first flow channel 74 having the bent-pipe shape is formed between the first outer plate 71 and the intermediate plate 73, and the second flow channel 75 having the bent-pipe shape, is formed between the second outer plate 72 and the intermediate plate 73 so as to overlap the first flow channel 74 through the intermediate plate 73. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
