The paper "Effect of Subcooling on Pool Boiling of Water from Sintered Copper
Microporous Coating at Different Orientations" presents experimental results of a subcooling effect on pool boiling heat transfer using a copper microporous coating water a comparison with those of a plain surface.
Each heat pipe has a copper tube and sintered copper
wick structure, and contains distilled water as its working fluid.
