Influence of ethanol and n-butanol additives on spray cooling
Spray cooling is the most promising cooling method in the field of high-power electronic device cooling. Different concentrations of low alcohols (ethanol and
n
-butanol) were added into deionized water to improve the heat transfer performance of spray cooling. The experimental system was established and the effect of concentration on heat transfer characteristics was investigated. The results reveal that an optimal concentration exists by adding low-alcohol additives into deionized water. The performance of spray cooling is gradually enhanced with increasing concentration before the optimum concentration. The optimum concentration of ethanol is 4% and the optimum concentration of
n
-butanol is 0.5%.
