“…Therefore, different studies have been employed to enhance carbon foam properties. Infiltration carbon foam with phase change material (PCM) was used to improve the foam heat capacity as well as the PCM thermal conductivity 10‐15 . Recently, Meng et al 16 examined the impact laws of porosity and pore density of copper foam to improve the thermal performance of the composite of paraffin‐metal foam PCM.…”

Summary The overall decrease in the size and the weight of electronic components has led to high power dissipation and the need for innovative cooling designs. The current work presents an experimental study that has been conducted to use several types of pristine and coated carbon foams as heat sink and heat exchanger in a thermoelectric cooler for cooling vest application. Various parameters were measured and calculated to investigate the performance of carbon foam. Such parameters are weight, effective thermal conductivity, mass flowrate, the outlet temperature for both heat sink, and heat exchanger in addition to their temperature difference. The results from this work were compared to a previous study conducted on aluminum fins. The results showed that the coating technique improved the thermal conductivity of the foam with low thermal conductivity more than the foam with high thermal conductivity. The performance of carbon foam was much better than aluminum in dissipating the heat, especially for the high thermal conductive carbon foam. The largest weight value of the foam was around 70% of aluminum fins, while its thermal conductivity was 300% more. The foam has the potential to improve heat transfer, thus reducing the size and the weight of equipment while simultaneously increasing its efficiency and capabilities.

“…Nano-enhanced phase change materials (NEPCM) are usually indicated modified thermophysical properties in addition to the thermal conductivity like viscosity, specific heat capacity, and latent heat. 13 Nanoparticles with high thermal conductivity are commonly incorporated in PCM with a lower concentration ratio (CR) of 5%. Although increasing the nanoparticle amount provides higher thermal conductivity of NEPCM, an upper limit for CR has been reported typically.…”

A novel passive cooling heat sink for thermal regulation of concentrated photovoltaics (CPV) and its performance improvement based on phase change material (PCM) embedded in the metal foam has been introduced in this study. Eighteen different patterns have been considered for the heat sink to investigate the influence of series/parallel porosity gradient arrangement, foam material gradient, inclination angle, and pore density. A computational fluid dynamics simulation has been developed to analyze the transient heat charging mechanism and evaluate the effects of porosity/material gradient with different arrangements on the conduction/convection heat transfer processes in the foam-PCM-CPV. The results revealed that parallel positive porosity gradient in y-direction could enhance the natural convection and the conduction heat transfer compared to the series negative porosity gradient in the xdirection and reduce the time-average CPV temperature by 6.76 C and enhance the time-average electrical efficiency by 3.93%. The results also indicated that using an obtuse inclination angle instead of anacute one may reduce the CPV temperature by about 5 C and leads to an electrical efficiency improvement of 2.65%. The lower value of pore density is another determinative factor that could enhance the total absorbed heat by about 12% for different patterns.
