ABSTRACT:

which degrades its performance. So to improve the performance of device, it is necessary to maintain device at room temperature. For maintaining the temperature heat sink is used, which extract heat continuously from the heat source and maintain temperature in the permissible range. The performance of heat sink depends on the different process parameters. So to improve the performance of heat sink, here in this work effect of different shapes of perforated fins was analysed. For analysing the effect of different shapes of perforation on heat sink fins, it considered four shapes of perforation. Through analysis it is found that heat sink fins having circular perforation shows maximum heat transfer and lower thermal resistance as compared to other shape. After analysing the effect of different shapes of perforation, it also analysed the effect of arrangement of perforation that is in-line and staggered. After CFD analysis of heat sink,
