Abstract:
A method for forming features in an exterior surface of a heat transfer tube includes forming a plurality of channels into the surface, where the channels are substantially parallel to one another and extend at a first angle to a longitudinal axis to the tube. A plurality of cuts are then made into the surface substantially parallel to one another and extend at a second angle to a longitudinal axis to the tube different from the first angle. Individual fin segments extend from the surface and are separated from one another by the channels and the cuts. The fin segments have a first channel-adjacent edge adjacent substantially parallel to the channel, a first cut-adjacent edge substantially parallel to the cut, and a corner formed by a second channel-adjacent edge and a second cut-adjacent edge. A tube formed using this method can be used as a condenser tube.

Claim (Index 1):
A heat transfer tube with an outer surface comprising\n a plurality of outwardly extending fins with channels extending between adjacent fins, the channels extending at a first angle to a longitudinal axis of the tube, a plurality of cuts formed on the fins, the cuts extending at a second angle to a longitudinal axis of the tube, the second angle being different from the first angle, the cuts producing fin segments, each fin segment comprising a stem, a top surface, and a deformed edge extending from and bending downwardly from the top surface, the deformed edge at least partially overlapping the cut adjacent to the fin segment.
