Abstract
A heat exchanger combines a lanced fin surface with a ruffled fin surface to create a lanced ruffled turbulizer. The lanced ruffled turbulizer combines the turbulence generated by lancing the heat transfer or turbulizer surface to the deflection forces on the fluid stream generated by a ruffled turbulizer to improve the thermal performance of the heat exchanger.
Claims14
A turbulizer comprising:
- a plurality of connecting interposing lines of fin forming a corrugated pattern and generated from a flat sheet of metal, said plurality of connecting interposing lines of fin defining a repeating corrugated pattern including,
- a first section approximately parallel to a horizontal and situated in a horizontal plane,
- a section approximately parallel to said horizontal and lying in said horizontal plane,
- a third section sloping downward at a first angle from a first top corner of said second section toward a first bottom corner of a successive occurrence of said first section, and
- a fourth section sloping upward at a second angle from a second bottom corner of said first section toward a second top corner of said second section.

A turbulizer comprising:
- a plurality of connecting interposing lines of fin having a surface, and
- means for simultaneously lancing and ruffling said plurality of connecting interposing lines of fin to define a repeating corrugated pattern.
A method for creating a turbulizer comprising the steps of:
- generating a continuous length of fin from a flat sheet of metal, said fin having a surface and further having a plurality of connecting interposing lines of fin;
- and
- defining a repeating corrugated pattern on said surface including,
- a first section approximately parallel to a horizontal and situated in a horizontal plane,
- a second section approximately parallel to said horizontal and lying in said horizontal plane,
- a third section sloping downward at a first angle from a top corner of said second section toward a bottom corner of said first section, and
- a fourth section sloping upward at a second angle from said bottom corner of said first section toward a top corner of said second section.
