Abstract
A heat exchanger, method of manufacturing, and manufacturing apparatus including at least one row of flattened tubes along which a heat exchange medium may pass. A serpentine fin is supported between adjacent tubes. The fin defines a plurality of louvers therein, each louver forming an elongated slit. A fluid to be heated or cooled by the medium may pass through the slit. A corrugated edge is formed upon one or more of the louvers for creating turbulence in the fluid. This turbulence disturbs laminar flow of the fluid across the associated louver and promotes a transfer of thermal energy between the medium in the tubes and the fluid.
