Heat exchanger, fluorination method of heat exchanger or its components and manufacturing method of heat exchanger |
摘要 |
The heat exchanger according to the present invention includes a heat exchanger component in which a fluoride layer 10 is formed at the surface layer portion. It is preferable that the fluoride layer 10 falls within the range of from 2 nm to 10 mum in thickness. It is preferable that the component is at least one of a fin and a plate. Furthermore, it is preferable that the fluoride layer 10 is formed on a substrate via an intermediate layer 2. It is preferable that the intermediate layer 2 includes an anodized oxide layer 3 and/or a nickel plated layer 4. The heat exchanger is excellent in corrosion resistance against water, vapor and the like The heat exchanger is preferably used, especially, for a fuel cell.
