The bent portion 11a on the side of the tube 11 where the fin 12 does not exist is a single long sacrificial anode plate 1 formed by pressing a thin plate made of the same material as the fin 12.
3.

この第2実施例における熱交換器も、第1実施

The outer surface of each of the upper two bent portions 21a in FIG.
It is covered with a sacrificial anode piece 22b formed by extending the end of the lower fin 22 upward, and the outer surface of the lower bent part 21a has a sacrificial anode plate 23 similar to the first embodiment. covered.

この第3実施例における熱交換器もまた、第1

As is clear from the above, according to the present invention, the curved part of the tube where no fins are present is coated with the same sacrificial anode material as the fins, so that the corrosion resistance of this part, which was conventionally most susceptible to corrosion, is improved. This is extremely meaningful.
