Experimental investigation on the thermal management performance of heat sink using low melting point alloy as phase change material

Thermal performance of phase change material–based heat sink for passive cooling of electronic components: An experimental study

“…It can be seen from the figures that base temperature of heat sink obtained from the present study follows similar pattern as reported by various researchers. 21,37,55,[58][59][60][61][62] However, the variation in the results obtained from the present experimental investigation with the existing test results may be due to the change in the heat sink design, the melting point temperature of PCM, and starting temperature of PCM in the experimental investigation.…”

“…In order to validate present experimental results, the base temperature (T b ) of the heat sink obtained from the present experimental study is compared with the test data of Arshad et al, 21 Mahmoud et al, 37 Tauseef-ur-Rehman and Ali, 55,59,60 and Tauseef-ur-Rehman et al 58 ( Figure 9A, B). Most of the studies consider heat sink having dimension of 100 × 100 × 25 mm 3,55,[58][59][60][61][62] (56 C-58 C) 21,58,59 for the analysis. Studies also consider Rubitherm RT-42 with melting temperature of 42 C, 37 stearic acid with melting temperature of 68.77 C 61 and lauric acid with melting temperature varying between 42 C and 44 C 62 for the analysis.…”

Magnetically tightened form-stable phase change materials with modular assembly and geometric conformality features

“…The 3D structural substances act as not only the thermal conductivity promoter but also supporting materials, which signi cantly decreases the ller loading of PCMs. Among these substances, 3D carbon materials and metal foams are the most frequently used additives 18,19,20 .…”

“…It is particularly di cult for them to construct an interconnected thermal conduction framework, and the resulting materials often present extremely low thermal conductivity due to the loose contact, which means the increase in thermal conductivity of the as-prepared form-stable PCMs is very limited 21,22 . As for metal foams, it is not easy to impregnate PCMs into their inner pores and obtain thoroughly lled composites because of the large surface tension or insu cient wetting of PCMs to the metal 19 . Up to now, the effective method to synthesize form-stable PCMs is still lacking and further explorations are in demand.…”

Synthesis and Characterization of Nanoalumina and CNTs-Reinforced Microcapsules with n-Dodecane as a Phase Change Material for Cold Energy Storage

“…The techniques for effective utilization of renewable energy sources have drawn widespread interest owing to energy shortages and environmental problems caused by the emission of greenhouse gases. − Recently, thermal energy storage (TES) technology has been considered as a promising technology to solve environmental pollution and energy shortage. , Latent thermal energy storage (LTES), sensible thermal energy storage (STES), and thermochemical energy storage (TCES) are three common types of TES. , LTES technology using phase change materials (PCM) has been universally accepted in various fields due to the fact that PCM can absorb and release a very highly density of latent heat at almost constant temperature during the phase transition. − PCMs are divided into three types: organic materials, inorganic materials, and eutectic materials. , Among organic materials, many researchers are committed to the use of alkanes (in the following abbreviated to C n ) as PCM in energy storage applications due to the merits of innocuousness, being noncorrosive, having chemical stability, and having high latent heat, etc. , However, C n has the shortcomings of leakage, volume expansion, and low thermal conductivity . Microencapsulation is a commonly used technique to overcome the leakage problem and volume expansion of C n by encapsulating them inside the resin shell, , and the thermal conductivity can be improved by adding highly conductive nanoparticles such as metal and carbon nanoparticles, etc. , …”
