Saturation Boiling Videos

ISNPS is currently investigating pool boiling of dielectric liquids as a method of cooling high powered electronics in anticipation of the development of more powerful and compact computers. Using porous graphite and finned copper surfaces, heat fluxes in excess of 70 W/cm2 have been dissipated in boiling of HFE-7100. To explore the effect that various parameters have on boiling heat transfer, experiments are performed using different liquids (HFE-7100 and FC-72), at different subcoolings (0 K to 30 K subcooling), different surface orientations (0º to 180º), and on different surfaces (plane and finned surfaces made of copper and porous graphite). Still images and video helps to understand and explain the boiling phenomena. Below are links to videos of showing pool boiling under several different conditions.
