Abstract: Thermal design of miniaturized electronic equipment is becoming challenging with increased heat fluxes, acoustic disadvantages with enhanced noise from fans that cause forced convective cooling and also restriction in space for the placement of fans itself. Present study aims at evaluating the efficiency of a micro piezo electric fan in cooling a heat sink (20*20) mm2 provided with an array of pin fins (6*6). FLOTHERM is used to do the CFD analysis and heat transfer analysis to determine the optimized spacing of fins.It is found that the best configuration has reduced the hot spot temperature from 1670C to 64.10C.
