Abstract: <P>PROBLEM TO BE SOLVED: To provide an high performance heat exchanger having excellent pressure resistance and material selectivity and a method of manufacturing the heat exchanger.  <P>SOLUTION: This heat exchanger 10 comprises a plurality of first heat transfer tubes 1 for flowing first fluid therein, a guide tube 3 enclosing and fittedly holding these tubes in a row, and a second heat transfer tube 2 for flowing second fluid therein. A guide tube 2 and the second heat transfer tube 2 enclosing the first transfer tube 1 are spirally wound while being alternately fitted to each other. Since the first heat transfer 1 is not formed in a multi-hole structure, the first heat transfer tube can be formed of not only aluminum but also various materials such as copper and stainless steel. In addition, since the guide tube 3 is formed to enclose the plurality of first heat transfer tubes 1, the guide tube 3 has excellent productivity and is formed to be closely fitted to each other in the row. Therefore the guide tube 3 can form a relatively wide heat transfer surface. Also, since the heat transfer tubes are formed to be spirally wound closely to each other, a sufficiently wide heat transfer area can be secured in the heat exchanger.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
