Abstract

An experimental investigation of pool boiling heat transfer under saturation condition on a vertical oriented copper surface has been performed. A highly wetting dielectric fluid, Novec 7100, is used as a working fluid. A copper block heated by a ceramic heater was fabricated to simulate a high power density electronic chip. The input power is adjustable and ranged from the value that can initiate boiling to the point that transition boiling stage is reached. The boiling curves of saturated Novec 7100 liquid on the copper surface are obtained. The boiling curves are found to deviate in several runs with fresh and used liquids due to the degradation in heat transfer in the used liquid. The boiling process is also observed and recorded through a high-speed camera.
