ABSTRACT

Heat removal from a straight fin with longitudinal elliptical holes is studied. 1D numerical simulation of the fin thermal dissipation performance is carried out by using the finite element technique. The perforations make full use of boundary-layer effect to improve heat transfer efficiency. The perforated fin is segregated into several elements using automatic mesh generation procedure. The number of finite elements can be changed as necessary according to the solution stability and convergence. The heat dissipation is calculated and matched up to that of the solid fin of similar measurements and physical properties. The assessment passes on satisfactory outcomes.
