<P>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of preventing deformation of a tube due to an internal pressure, and deformation of an outer fin by considering arrangement of an uneven cross section of an inner fin. <P>SOLUTION: The heat exchanger is provided with plurally laminated tubes 110 communicating internal fluid in interiors, the inner fin 120 inserted in the tube 110 and formed so that uneven cross sections are discretely arranged, and the outer fin 130 interposed between the tubes 110, and it carries out heat exchange between the internal fluid and external fluid passing the outer fin 130. Recessed parts 121 and protruding parts 122 of the uneven cross section are arranged in positions that respectively match when looking at a projection of each inner fin 120 from a laminating direction of the tubes 110. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
