Web1 day ago · Ali et al. [26] conducted an experimental study for electronic cooling on a square and circular heat sink layouts with pin fins as a thermal conductivity enhancer. Experiments with two PCMs, paraffin wax and n-eicosane, and two fin configurations (2 mm square fin and 3 mm diameter circular fin) were performed. Web2–22 for fins on a plain surface and in figure 2–23 for circular fins of constant thickness. The fin surface area associated with each profile is also given on each figure. For most fins of constant thickness encountered in practice, the fin thickness t is too small relative to the fin length L, and thus the fin tip area is negligible. the park uriah heep
