Thermal analysis has been performed in this work on a different designs of fin in order to investigate the temperature distribution, heat flux, and thermal stresses using ANSYS workbench. For this work total nine designs of fin have been created such as rectangular plate fin, rectangular plate fin with hole, rectangular perforated fin, rectangular plate fin with slot, rectangular plate with pin inserted fin, rectangular plate inserted pin with hole fin, triangular plate fin, triangular plate with perforated fin & triangular plate fin with slot. Aluminum 1060 is used as a material for all designs of fin, The 13 W of heat supply at the bottom of the fin have been applied which is equal to the power supply at ambient temperature of 22 oC. Results show that the 48.76 oC is the lowest temperature for the rectangular plate inserted pin with hole fin which is 8.9% lower than the plane rectangular plate fin and the 51.67 oC is the lowest temperature for the rectangular plate fin with hole which is 5.5% lower than the plane rectangular plate fin while the 0.0378 W/mm2 is the lowest temperature for the triangular plate fin with slot which is 3.5 times greater than the plane rectangular plate fin. The 7.3 degree is the highest temperature difference for the rectangular perforated fin which is 4.2 times higher than the plane rectangular plate fin and the 0.0276 MPa is the lowest thermal stress for the rectangular plate fin with hole & triangular plate with perforated fin which is 5.74 times lower than the plane rectangular plate fin. Hence the rectangular plate inserted pin with hole fin is suggested for better heat transfer.
