ABSTRACT:
A flat heat exchanger fin includes a body having arrays of louver groups formed therein. Each array includes four louver groups. The first and second louver groups are disposed over a respective pipe, with the second louver group disposed behind the first louver group. The third and fourth louver groups are disposed beneath a respective pipe, with the fourth louver group disposed behind the third louver group. Each louver group includes a plurality of louvers which form slits through the body. The slits extend transversely relative to the air flow direction and generally radially with respect to the respective pipe. Each louver group includes a proximate edge facing a respective pipe, and a remote edge facing away from the pipe. The remote edge is spaced from the respective pipe by a substantially constant separation distance. Dew-draining ridges are formed in the fin above, below, in front of, and behind respective pipes.
