A SERRATED HEAT EXCHANGE FIN AND A HEAT EXCHANGE FINNED TUBE

摘要

A new type of segmented fin (12) for use on a finned tube (18), the unique type of finned tube (18) that is created with the new type of segmented fin (12), specialized serrating wheels (14 and 16) for creating the new type of segmented fin (12), and the process (10) for employing the specialized serrating wheels (14 and 16) to create the new type of segmented fin (12). Each of the segments (26) of the new type of segmented fin (12) is permanently curved, and the segments (26) are coined to increase surface area of the segments (26) and to further shape the sheared edges (42 and 44) of the segments (26) into a more pointed configuration in order to make them more aerodynamic.
