摘要:
A heat exchange tube includes a tubular member having a flattened cross-section and extending along a longitudinal axis, and a longitudinally extending condensate drain channel formed in an upper wall of the flattened tubular member. A heat exchanger includes a first and a second spaced apart and generally vertical longitudinally extending headers, a plurality of heat exchange tubes disposed in parallel, spaced relationship in a generally vertical array and extending longitudinally between the first header and the second header, and a condensate drain extending longitudinally along, the upper wall of at least one of the plurality of flattened heat exchange tubes. The condensate drain may comprise a longitudinally extending condensate drain channel formed in an upper wall of said flattened tubular member, and/or a series of condensate drain portals formed in the heat transfer fins in a base portion bounding to the upper external surface of at least one heat exchange tube. The condensate drain portals of neighboring heat transfer fins are aligned longitudinally to provide a series of longitudinally aligned condensate drain portals along the upper external surfaces of the heat exchange tubes.
