Title:Improving Thermal Conductivity in Heat Sink Using Copper Foam-Paraffin Phase Change Materials
Abstract:Phase change materials (PCMs) play a vital role in thermal energy storage systems because of  their  ability  to  absorb  and  release  heat.  However,  their  low  thermal  conductivity limits how quickly energy can be stored and retrieved. Adding copper metal foam toPCMs  significantly  improves  their  thermal  conductivity.  This study explores the  increase  in thermal conductivity of a metal foam-paraffin composite compared to pure paraffin. Copper metal  foam,  known  for  its  excellent  thermal  conductivity,  enhances  the  heat  transfer  rate within  the  composite.  Both  theoretical  and  experimental  evaluations  were  conducted  to measure  and  compare  the  thermal  conductivity  of  the  copper  foam/PCM  composite.  The results  showed  that  the  composite  achieved  a  thermal  conductivity  of  5.5  W/mK  at  13  Wmuch  higher  than  the  0.2  W/mK  observed  in  pure  PCM.  Additionally,  the  copper/PCM composite reduced the heat sink temperature by 25–30%. This improvement is attributed to the  enhanced  thermal  pathways  created  by  the  structure  of  the  copper  foam,  despite  the inverse relationship between infiltration ratio and pore density.
