Study on the interfacial thermal conductance between metals and phase change materials

Abstract Foam metal phase change composite materials and systems play a crucial role in the heat (cold) storage system. The interfacial thermal conductancebetween different foam metals and phase change materials under different phases isan important factor to affect the heat (cold) storage process of theheat (cold)storagesystem. In this paper, the interfacial thermal conductancebetween the three metals(copper, aluminum and nickel) andtwo phase change materials (paraffin and erythritol) in solid and liquidis measured by time-domain thermoreflectanctechnique. The experiments suggest that regardless of the types (paraffin or erythritol) and phases (solid or liquid) of phase change materials, the interfacial thermal conductance results preserve the same trend that copper
