Abstract

Annular fin has used widely in the industrial application that need heat transfer from higher to lower temperature and there are several type of fin that commonly been used in industry such as straight rectangular fins, straight triangular fins, straight parabolic fins, circular fin of rectangular profile, pin fins of rectangular profile, pin fins of triangular profile, pin fins of parabolic profile, and pin fin of parabolic profile (blunt tip). By using the theoretical study the best performance of the annular heat sink is predicted and few parameters are taking into consideration such as pitch diameter of fin, number of fin and also thickness of the fin. The overall allowable size of this heat sink is 180 mm x 98 mm x 20 mm. In the end of this study, it is found that the best efficiency is 93.28% achieved at case 4 where the thickness is 3 mm and pitch diameter is 4 mm at 25W/m2.K of convection heat transfer coefficient. In the end of the analysis, it can be said that the fin thickness is one of the important variable that need to consider because it effect the overall efficiency of the fin. The experimental should be done to compare the result of theoretical study and fabrication of heat sink need to be done.
