Preparation and thermal property analysis of Wood’s alloy/expanded graphite composite as highly conductive form-stable phase change material for electronic thermal management

Using phase change materials (PCMs) for passive cooling is an effective thermal management technique as they absorb and release large amount of latent heat. However, PCMs have low thermal conductivity and liquid leakage often occurs after the solid-liquid phase transitions. In this study, a Wood’s alloy/expanded graphite composite PCM was developed to achieve desirable thermal performance. The thermal conductivities of the composite samples were measured, based on a ...

Thermally conductive MgO-Filled Epoxy Molding Compounds

Despite their tendencies to have low thermal conductivities, epoxy molding compounds (EMCs) are extensively used in automotive applications. In this study, magnesium oxide (MgO) was used as a conductive filler in ECMs to improve the thermal conductivity of the ECMs without altering other important characteristics. A thermal constants analyzer was used to measure the thermal conductivity of the MgO-EMC composites. Ultimately, one of the prepared MgO-EMC compounds was found to ...

Thermal properties of carbon nanotube reinforced metal composites

The application of carbon nanotubes (CNT) to thermal management devices has recently drawn much attention. This study produced and examined metal-carbon nanotube composites for use in highly conductive yet stable thermal management materials. The structural and thermophysical properties of metal-CNT composites were examined, including the measurement of thermal conductivity using the Thermal Constants Analyzer TPS transient plane source (TPS) method. Results showed that generally, inverse relationships were observed between thermal ...


Direct Low-Temperature Integration of Nanocrystalline Diamond with GaN Substrates for Improved Thermal Management of High-Power Electronics

This study aimed to develop a new technique for thermal management in high powered gallium nitride (GaN) electronic and optoelectronic devices. The researchers integrated GaN with diamond through the process of depositing high-quality nanocrystalline diamond films directly onto the GaN material at temperatures between 450-500°C. Highly controlled growth conditions for the diamond ensured that it was of good quality. Thermal conductivity measurements using the laser flash method were performed ...

Toward lithium ion batteries with enhanced thermal conductivity

Li-ion battery electrodes are typically mixed with carbon black materials which have low thermal conductivity in high-power-density battery applications. In this study, multi-walled carbon nanotubes (MWCNTs) were added to Li-ion battery electrodes to improve thermal conductivity. A measured the thermal conductivity of the electrode samples at room temperature using the transient plane source (TPS) method. Results showed that the addition of MWCNTs enhanced the thermal conductivity of the electrodes by ...
