Heat Transfer Improvement of Phase Change Material With Metal Foam

Temperature control is essential to the stable performance and lifetime of electronic products. Phase change materials can absorb the heat generated by electronic components or devices and keep the product's temperature steady during the phase change process. However, the low thermal conductive properties limit their applications in the thermal management of high density electronics. Metal foams are used as thermal conductive enhancer to improve the heat transfer of paraffin wax in this paper. The effective thermal conductivities and heat transfer features of composite are investigated by numerical simulation. Various structures and materials of metal foams are taken into consideration, and the phase change characteristics are studied.
