Pool boiling heat transfer from plain and microporous, square pin finned surfaces in saturated FC-72

摘要

The present research is an experimental study of "double enhancement" behavior in pool boiling from ehater surfaces simulating microelectronic devices immersed in saturated FC-72 at atmospheric pressure. The term "double enhancement" refers to the combination of two different enhancement techniques: a large-scale area enhancement (square pin fin array) and a small-scale surface enhancement (microporous coating). Fin lengths were varied from 0 (flat surface) to 8 mm.
