Thermal interface materials (TIMs) are often used in electronic and microelectronic applications. It can be difficult to determine their characteristics once they are in-situ because it is hard to account for the surface roughness and waviness of the objects the TIM is applied to. This paper explores the application and design of a guarded heat flow meter apparatus that complies with all standards in ASTM D 5470-95 that can accurately ...
This article reviewed the use of phase change materials (PCM) as thermal energy storages (TES) as they can be used to substitute large-scale energy demand and assist both economically and environmentally. The thermophysical properties of different phase change materials were studied to assess their viability for thermal storage systems. One of their most common problems with using PCMs is their poor heat transfer rates. This was seen when the transient ...
In this study, thermal behaviors of an integrated thermal management system (ITMS) with phase change materials (PCMs) and air conditioning exhaust are examined. To enhance thermal conductivity of the PCM, copper foam and paraffin were added. Thermal conductivity of the composite PCM was measured by a thermal analyzer, based on the transient plane source method....
Polymeric composite materials were prepared by one-pot synthesis of chromophoric polymer phase change material in nitrogen-doped porous carbon (NPC). Thermal conductivity was found to increase with increasing NPC wt%, enhancing the heating rate with a shorter phase change period....
With a goal of wider usage of renewable energy sources that are clean and sustainable, effective technologies, such as thermal energy storage (TES), play a vital role in storing thermal energy for future use. In this study, silver nanoparticles were dispersed in paraffin wax, eicosane, as phase change material (PCM). Thermal conductivity was measured following the transient method, using a Thermal Constants Analyzer with transient plane source technique. Thermal conductivity ...
