Abstract

• Effects of concentration on flow boiling of ethylene glycol/water mixtures studied. • Show superior heat transfer performance for 50% mixture in the present heat sink. • Attained heat flux of 407 W/cm 2 and heat transfer coefficient of 8.41 W/cm 2 K. • Two-phase flow pressure drop close to that of single-phase flow at same mass flux. • Great potential for cooling in a future insulated-gate bipolar transistor module.
