Abstract (en)

[origin: EP0962736A2] An improved corrugated heat conduction fin (20) for an evaporator (10) includes an integral feature for reducing the critical width of condensed water films retained in the internal channels formed between diverging pairs of fin walls (22). Aligned pairs of notches (26) are cut through the diverging fin walls (22), localized within the channels and between adjacent pairs of louver banks (24). What would otherwise be a long, continuos water film (F) formed in the fin channel is thereby broken up into a series of discontinuous individual films (F1, F2 and F3), each located over a respective louver bank (24). The individual, shorter films drain more efficiently through the louver banks (24), thereby growing to a significantly smaller critical width within the channels and blocking less air flow over and through the fin walls (22). <IMAGE>
