Abstract

An experimental investigation of the Critical Heat Flux (CHF) and heat transfer coefficient (HTC) of two-phase heat transfer of de-Ionized (DI) water, pool boiling was conducted using several kinds of sintered copper microparticle porous uniform and modulated structures. The modulated porous structure reached a heat flux of 450 W/cm2 and a heat transfer coefficient of 230,000 W/m2K. The thick and thin uniform porous structures achieved CHFs of 290 W/cm2 and 227 W/cm2 , respectively, and heat transfer coefficients of 118,000 W/m2K and 104,000 W/m2K. The mechanisms for the dramatically improved CHFs and HTCs were identified with assistance of a visualization study.
