<P>PROBLEM TO BE SOLVED: To provide a heat exchanger can reduce the number of components and reducing its size and weight. <P>SOLUTION: In this heat exchanger, a plurality of U-shaped heat exchange tubes 2 respectively comprising a pair of flat straight tube sections 21 disposed in parallel with each other in the width direction, and a turn section 22 for communicating and connecting end portions of the pair of straight tube sections 21, are arranged in parallel with each other along the tube thickness direction. In this heat exchanger, the heat exchange tube 2 is formed by obliquely folding a strip-like flat tube member 20 at both ends of an intermediate section in the longitudinal direction, the intermediate section of the flat tube member 20 is constituted as the turn section 22, and both side sections of the flat tube member 20 are constituted as a pair of straight tube sections. <P>COPYRIGHT: (C)2009,JPO&INPIT |
