Phase change materials (PCMs) can be used as heat sinks to manage high temperature fluctuations in electronics. In this paper, a heat sink was generated from a paraffin/expanded graphite composite PCM, and the thermal conductivities of the materials were measured using the transient plane source (TPS) method of the Thermal Analyzer. Results showed that the composite PCM had a significantly higher thermal conductivity than the pure paraffin....
The authors created a series of composite latent storage materials (CLSM) using expanded graphite (EG) and a two different metal nitrate phase change materials (K and Li, K and Na). The steady-state comparative method was used in order to measure thermal conductivities because it was deemed the best technique. Properties investigated that were related to the effective thermal conductivity were material temperature and microstructure and their effect on thermal conductivity....
Thermal conductivity and thermal diffusivity of two poly(methyl methacrylates) were measured using multiple methods; temperature wave analysis, laser flash, transient plane source, transient line-source probe, and heat flux meter. The main reasoning behind this study was to compare results between methods, to ensure repeatability among methods. Good agreement was shown among thermal conductivity and thermal diffusivity results between instruments, however the transient plane source method repeatedly yielded 6% higher results ...
