Abstract
An evaporator (10) with opposed pairs of generally vertically oriented flow tube surfaces (14) has corrugated air fins in which the tube surface spacing c, the interior radius r of a crest (20) joining adjacent pairs of fin walls (18), the fin pitch p separating adjacent crests (20), and the length l of louvers (22) cut out of the fin walls (18) 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.
