Abstract
A twisted-louver high performance heat exchanger fin assembly includes a plurality of fin elements each having a louver formed therein. The louvers include first and second portions connected by a twisted portion such that the first and second portions cross in an X-shaped profile.
Claims7
A twisted-louver high performance heat exchanger fin assembly comprising:
- a plurality of fin elements, each said fin element having first and second portions extending in associated generally parallel planes;
- a first louver portion formed in said fin element first portion, said first louver portion being generally planar and extending at a first predetermined angle from said plane of said fin element first portion;
- and
- a second louver portion formed in said fin element second portion, said second louver portion being generally planar and extending at a second predetermined angle from said plane of said fin element second portion, said first and second louver portions connected by a twisted portion and crossing in an X-shaped profile, wherein a width of said first louver portion, a width of said second louver portion, and a width of said twisted portion are substantially equal.

A twisted-louver high performance heat exchanger fin assembly comprising:
- a plurality of fin elements, each said fin element having first and second portions extending in associated generally parallel planes connected by a curved central portion;
- a first louver portion formed in said fin element first portion, said first louver portion being generally planar and extending at a first predetermined angle from said plane of said fin element first portion;
- a second louver portion formed in said fin element second portion, said second louver portion being generally planar and extending at a second predetermined angle from said plane of said fin element second portion, said first and second louver portions crossing in an X-shaped profile;
- and
- a twisted portion connecting said first and second louver portions, wherein a width of said first louver portion, a width of said second louver portion, and a width of said twisted portion are substantially equal.
