Preparation and thermal performance of paraffin/Nano-SiO2 nanocomposite for passive thermal protection of electronic devices

Controlling the temperature of electronics under harsh conditions is important for vehicular, aerospace, and other industrial applications. Phase change materials (PCMs), such as paraffin, use latent thermal energy storage (LTES) to store large amounts of latent heat over small temperature ranges, and are being investigated for use in industrial sectors. However, PCMs have low thermal insulation capabilities so porous matrices with low thermal conductivities are often used to decrease the ...

Preparation and thermal characterization of composite -oeParaffin/Red Brick- as a novel form-stable of phase change material for thermal energy storage 

This study is to determine the thermal properties of a paraffin/red brick composite to determine its viability as a form-stable phase change material. Extended graphite was also added to the composite to improve its thermal conductivity. The thermal conductivity for this material was measured using a transient plane source (TPS) method. By adding the paraffin, the thermal conductivity of the composite increase, also by adding extended graphite the thermal ...

Preparation and thermal characterization of paraffin/metal foam composite phase change material 

Paraffin is an excellent phase change material (PCM) for latent heat storage, but it does not efficiently use stored energy because of its low thermal conductivity. In this study, nickel and copper foams were added to paraffin to enhance heat transfer. A Thermal Constants Analyzer measured the thermal conductivity of the paraffin composites using the transient plane source (TPS) method. The addition of copper foam enhanced the thermal conductivity of ...

Experimental research on heat transfer mechanism of heat sink with composite phase change materials 

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....

Temperature-dependent thermal properties of a paraffin phase change material embedded with herringbone style graphite nanofibers

The authors outline a method of enhancing the thermal properties of a paraffin phase change material through the addition of herringbone-style graphite nanofibers (HGNFs). It was found that the solid-phase thermal conductivity increased exponentially with the presence of HGNFs; however, a significant increase in the liquid-phase thermal conductivity was not observed until the concentration of HGNFs in the composite PCM reached a point above the percolation threshold. The volumetric heat ...
