<p><P>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving corrosion resistance without degrading heat exchanging performance, and suppressing manufacturing costs. <P>SOLUTION: This heat exchanger 1 includes a core section constituted of plates 11, corrugated fins 12, and side bars 13 as main components. The plates 11 have the rectangular shape, and the plurality of plates are arranged in parallel with each other at prescribed intervals in the thickness direction. The corrugated fins 12 are respectively disposed between the plates 11, and the side bars 13 are disposed on both edge sections corresponding to opposed sides of a set of the plates 11. Surfaces of the plates 11, the corrugated fins 12 and the side bars 13 are provided with coatings made of titanium dioxide or zirconium dioxide and having a film thickness of 0.2-5μm. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
