Abstract
A method for manufacturing a heat exchanger includes: assembling a plurality of heat exchanger components in an assembly step; and forming a film on surfaces of the heat exchanger components using a chemical vapor deposition method in a film formation step after the assembly step. The film can restrict a formation of a through hole due to corrosion. The film can be restricted from being damaged at a delivery or assembling time, because the film formation step is provided after the assembly step. An occurrence of clogging can be restricted at a minute portion inside of the heat exchanger in the film formation step, because the film is formed using the chemical vapor deposition method.
