<P>PROBLEM TO BE SOLVED: To fully exchange heat even in the quality of a material where an element has a relatively low heat resistance against a high-temperature gas in a heat exchanger made of a laminate in the drawn cup type element having a pair of saucer-shaped plates 7a. <P>SOLUTION: A first core 3 having a number of tubes 6 with circular sections is provided at an upstream side. A second core 4 made of the laminate in a drawn cup type element 7 is arranged at a downstream side. The high-temperature gas 1 is passed through the first core 3, and then is passed through the second core 4. <P>COPYRIGHT: (C)2004,JPO |
