Abstract
An evaporator ( ) with opposed pairs of generally vertically oriented flow tube surfaces ( ) has corrugated air fins in which the tube surface spacing c, the interior radius r of a crest ( ) joining adjacent pairs of fin walls ( ), the fin pitch p separating adjacent crests ( ), and the length l of louvers ( ) cut out of the fin walls ( ) bear the following relationship: 0≦r/c≦0.057, 0.89≦l/c≦1.01, and 0.29≦p/c≦0.43. This has been found to substantially improve condensate drainage, while not significantly penalizing heat transfer or air side pressure drop.
