摘要

A special profile for the surface of a heat transfer member is described in which downwardly inclined grooves are formed with convexly curved crests whose radius of curvature decreases to a minimum at the peak where it substantially is less than the minimum radius of the adjacent troughs. A ratio of 1 : 10 is mentioned. The feature is applicable to grooves with an undercut flank on one side of the crest, useful on vertical condensing surfaces in assisting run off of condensate.
