“…As previously discussed, numerous inorganic fillers such as silica, alumina, and BN have been studied in order to improve the rate of heat transportation and also minimize the CTE of polymeric nanocomposites (Liem and Choy 2013). Because of its inherently good mechanical properties, electrical insulative properties, low CTE, and low cost, silica is an extremely attractive nanofiller applied in the improvement of thermomechanical properties of polymers in microelectronic device applications (Wuttig and Yamada 2007, Burr et al 2010, Warzohaand and Fleischer 2014, Horibe et al 2015. However, in order to attain the desired thermomechanical properties such as thermal conductivity of 0.3 W/m K and efficient CTE of 20-30 ppm/°C beneath the glass transition Tg, about 55-70 vol.% inclusion of micron-sized silica particles is required (Cui et al 2011).…”

“…This can be attained through improvement of its out-of-plane heat dissipation. Relative to through-thickness heat dissipation measurement techniques, many studies have been performed to determine the thermal conductivity of various materials which include both steady state methods and transient approaches (Wuttig and Yamada 2007, Burr et al 2010, Warzohaand and Fleischer 2014, Horibe et al 2015.…”

Due to escalating power densities in electronics, information, communication, energy storage, aerospace, and automobile technologies, heat dissipation has become immensely essential for the efficient performance and reliability of photonic, electronics, optoelectronics, and other devices in order to proactively prevent premature failure due to overheating. The functionalization and synergistic inclusion of thermally conducting nanoparticles such as carbon derivatives and metallic and ceramic fillers into polymer matrices have resulted in development of thermally conducting polymer nanocomposites. This has enlarged the scope of application of these materials in areas hitherto restricted due to poor thermal conductivity and, therefore, opened broad windows of opportunities for polymer nanocomposites as emerging alternative replacements for metal components in various applications where effective heat dissipation is compulsory for device performance. Thus, this paper critically discusses globally emerging technologies applied in the development of thermally conductive polymer nanocomposites for various industrial applications.

Today, latent heat storage technology has advanced to allow reuse of waste heat in the middle-temperature range. This paper describes an approach to develop a latent heat storage system using middle-temperature waste heat (~100˚C -200˚C) from factories. Direct contact melting and solidification behavior between a heat-transfer fluid (oil) and a latent heat storage material mixture were observed. The mixture consisted of mannitol and erythritol (C m = 70 mass %, C e = 30 mass %) as a phase-change material (PCM). The weight of the PCM was 3.0 kg and the flow rate of the oil, f oil , was 1.0, 1.5, or 2.0 kg/min. To decrease the solidified height of the PCM mixture during the solidification process, a perforated partition plate was installed in the PCM region in the heat storage vessel. PCM coated oil droplets were broken by the perforated partition plate, preventing the solidified height of the PCM from increasing. The solidification and melting processes were repeated using metal fiber. It was found that installing the metal fiber was more effective than installing the perforated partition plate to prevent the flow out problem of the PCM.

“…The study found that the local heat transfer coefficient was a strong function of the distance from the top of the ice block as well as the ambient liquid temperature. The direct contact heat storage and release characteristics of erythritol as a PCM with oil have also been investigated in a vessel with a partition plate (Horibe et al, 2015). The study reported that melting time decreased with increasing oil flow rate, and was accelerated by the effect of the heat conductivity of the perforated partition plate.…”

This study examined the melting behavior and heat transfer characteristics of a water-insoluble material immersed in water. n-Hexadecane, popularly used as a phase change material, was selected as the water-insoluble material. A rectangular n-hexadecane solid was immersed in water. The n-hexadecane block was then vertically fixed onto the copper plate of the cooling wall. The flow structure of the free convection of water was visualized by mixing tracer particles with the water, and a laser sheet entered from the opposite side of the cooling wall as a light source. Its melting behavior and melting rate were then observed under various water temperatures in a test vessel. The local heat transfer coefficients of n-hexadecane were calculated from its melting rate and latent heat. In addition, the thickness of the melting liquid of n-hexadecane was calculated using a simple analysis model. As the experimental results, it flows upward along the n-hexadecane block, accumulates at the top of the solid as a droplet, and then flows upward vertically because the melting liquid of n-hexadecane does not diffuse in water. The calculated thickness of the melting liquid of n-hexadecane increases drastically near the lower end and increases almost monotonically and at a mild rate in other parts of the block. The analytical and experimental local heat transfer coefficients showed good agreement at low water temperatures. The calculated local heat transfer coefficients changed slightly, except for those at the top and low parts of the block. The local heat transfer coefficients increased in most locations as time elapsed in the experiment.
