“…In addition, a combination with extra active cooling methods can ensure improved performance in the transient period and reliability in the steady state. 28 Here, the influence of forced convection on the performance of sorbent coating is also investigated. A DC fan was used to provide the forced airflow with an average speed of 0.8 m/s.…”

The application of traditional phase change materials (PCMs) in electronic thermal management is limited by their enthalpies. In this work, we adopt sorbents and their desorption processes to achieve efficient thermal management. The sorbents with high cyclic water loadings, such as MIL-101(Cr), significantly outperforms the traditional PCMs, by virtue of their high desorption heat during the temperatureinduced desorption process.

Improper operating temperature will degrade the performances of electronic components, Li-ion batteries and photovoltaic (PV) cells, which calls for a good thermal management system. In this paper, specific attention is paid to the thermal management systems based on phase change materials (PCMs). Performances of the PCM-based thermal management systems for for each kind of these three devices along with the type of PCM used, thermal properties of that kind of PCM, like phase change temperature, enthalpy of phase change and thermal conductivity are discussed. Discussion in detail on techniques to improve the thermal conductivity of PCMs are made because of its crucial influence. Advanced-structure heatsinks with multi-layer PCMs and hybrid passive heatsinks combined with active cooling are also introduced. The PCM-based thermal management system is powerful in ensuring electronic devices, Li-ion batteries and photovoltaic cells working safely and efficiently.

Table 2. Thermophysical properties of proposed PCM candidates-sugar alcohol, molten salt, and metallicwith phase-changing point over 100°C.from steelworks 2) has more enthalpy at lower temperature but more exergy at a higher temperature over 100°C. Table 3 lists frequently selected keywords from the collected papers. Papers on LHS and PCM frequently used general keywords such as "phase-change material", "PCM", "thermal energy storage", and "latent heat". Apart from these, interestingly, "solar energy" was also frequently used; these papers dealt with PCMs that can store solar energy through melting for various utilities. Keywords such as "phase-change composites", "thermal conductivity", "shape-stabilized" should be noteworthy in that these are related to general problems encountered during the use of PCMs, that is, capsulation and low thermal conductivity. Recent Advancements in LHS Technology PCM CapsulesGenerally, because LHS mainly utilizes the phase change between solid and liquid, the encapsulation of the PCM is necessary to avoid the leakage of a liquid PCM. In addition, Regin et al. 70) noted the functions and requirements of PCM containment: (i) meeting the requirements of strength, flexibility, corrosion resistance, and thermal stability; (ii) acting as a barrier to protect the PCM from harmful interactions with the environment; (iii) providing a sufficient surface for heat transfer, and (iv) providing structural stability and easy handling. PCM capsules are classified into macroand microcapsules.Macrocapsules are the most conventional PCM capsules, and many papers have reported various shell materials such as metal and plastics, and various shapes such as spherical [71][72][73][74][75] and cylindrical. 72,[76][77][78] In contrast, micro-encapsulation of PCM has recently attracted considerable attention [79][80][81][82][83][84][85] because it reduces the reactivity of the PCMs with the outside environment, increases the heat transfer area of the PCMs, and enables the core material to withstand frequent changes in the volume of the storage material during phase change. Table 4 lists trends in manufacturing methods for PCM capsules. Many papers have reported the production of various microcapsules, and the manufacturing methods, core PCM materials, shell materials, thermophysical properties, and capsule sizes of the same have been studied. Micro-interfacial polymerization, 80) in-situ polycondensation, [81][82][83][84][85] and complex coacervation 79) are the most popular microen- ISIJ International, Vol. 50 (2010), No. 9 79,80) 1232© 2010 ISIJ proposed the encapsulation of spherical metal PCMs such as Cu and Pb with an electroplated Ni layer to recover industrial hightemperature waste heat such as combustion offgas. The PCM spherical capsule with Ni coverage provided hybrid functions of both heat storage and catalysis. Nickel worked well as a catalyst of the gas phase reaction CH 4 ϩH 2 Oϭ 3H 2 ϩCO at 1000°C.In summary, the encapsulation of low-temperature PCMs is a state-of-the-art technology; in p...
