본 발명은 냉,온풍용 열교환기로 사용되는 냉,온수코일에 좁은간격으로 장착한 알루미늄 방열핀을 방청도료액으로 내부속까지 균일하게 도장할 수가 있는 냉,온수코일의 방열핀을 도장하는 장치에 관한 것이다.The present invention relates to an apparatus for coating a radiating fin of a cold / hot water coil, which can uniformly coat an aluminum radiating fin mounted at narrow intervals in a cold / hot water coil used as a cold / warm air heat exchanger, .

Especially, it is easily corroded when it comes into contact with air containing salt. Therefore, it is coated with anti-corrosive paint to prevent corrosion. However, it is very difficult to uniformly coat the radiating fin uniformly mounted on the cold and hot coils with the anti-corrosive coating liquid uniformly on the aluminum plate having the uniformly bent jig jig.
