Experimental Validation of Phase Change Material Cooling Performance Integrated into Finned Heat Sink

Abstract:

The aim of this study is to analyze the phase change material cooling performance integrated into heat sink experimentally. a paraffin wax as phase change material is used in this experiment and it placed under the heat sink with thickness 30mm , various power input at 11W,13W and 15W used in this experiment to generate heat at different levels also several fan speed at 15m/s,2.5m/s and 3.4m/s. the surface temperature of the heat sink is monitored over the time to evaluate the phase change material thermal performance . From the results ,temperature drop and the time lag in case of without PCM compared to with PCM shows the effect of cooling of adding PCM under low and high speeds of heat removal. It found that inclusion of PCM into heat sink with forced convection shows high temperatures drop up to 18 °C.
