摘要 |
A heat exchanger made of aluminum comprises a plurality of tubes (1) made of aluminum through which a fluid to be heat exchanged flows, the tubes having a metal surface of aluminum; fins (2) made of aluminum arranged between the tubes for accelerating heat exchange between the fluid to be heat-exchanged and air, the fins having a metal surface of aluminum; a first protecting film (8) of a chemical conversion coating formed on the metal surfaces (7) of the tubes and fins and containing a metal component; and a second protecting film (9) of an antimicrobial agent coating on the first protecting film, at least on the fins among the tubes and fins, the second protecting film having a chemical bond with the metal component of the first protecting film. An example of the antimicrobial agent is 2,2 min -dithiobis(pyridine-1-oxide). |
