As secondary source of heat transfer, heat sinks are primarily used. Heat generated by various equipments is first transferred to heat sink via conduction, after that heat is transferred to the environment. Heat sinks are thus used to maintain temperature of equipments under desirable range. CFD has recently emerged as an effective tool to judge performance of any equipment in design phase. CFD can also be used for design optimisation of heat sink also. In the present work, CFD analysis of heat sink has been carried out to find out the effect of change in air velocity. Effect of different materials used for the construction of heat sink on heat transfer (aluminium alloys that is AA-6063, AA-6061, AA-6060 and AA-1050) has been carried out. It has been found that material AA-1050 shows the maximum heat transfer as compared to other materials. The work has also been carried out for various thicknesses of base metals. It has been found that heat sink having 10 mm base thickness has maximum heat transfer.
