- Abstract
Numerical calculation with FEM was carried out for the fin efficiencies of common rectangular flat fin and three flat fins with modified geometry The result shows that the general heat tasfer performance of fin B2 is higher than that of common flat fin, but the fin efficiency is lower. Both the performances of heat transfer and fin efficiences of fin C and fin D are higher than those of common flat fin. The work of this paper is valuable for optimization design of high efficient fin.
