Abstract
Louver Fin geometry is one of interrupted surface type of fin. It has an extended surface heat transfer and may produce a certain structure of fluid flows expected to enhance the heat transfer coefficient. This structure of fluid flows influenced by parameters of louver fin as; louver pitch (Lp), louver angel (è ) and fin pitch (Fp).
Experimentally, the influence of these parameters to the rate of heat transfer was investigated. The results were compared to which of offset-strip fin, for the same surface areas.
The results of comparison shows although the geometry of louver fin (Lp/Fp = 1.1) with louver angel (è = 25 o ) causes pressure drop greater than offset-strip fin, but on the Re >9000, louver fin has a higher effectiveness than offset-strip fin does.
