As heat generation increases in CPUs and other small electronic devices, more miniaturized and efficient cooling technology has been required. In this study the authors investigated combination of impinging flow and high-carbon alcohol aqueous solutions in mini channel. T-junction channel made of quartz glass realized the impinging flow. The flow tube has a circle cross section, and the inner diameter was 2.0 mm. We performed experiments and compared heat transfer characteristics about concentration level of butanol aqueous solutions. The concentration level was 1.50wt%, 3.00wt%, 4.50wt%, and 7.15wt%. It was found from the experimental results that the boiling bubble of butanol aqueous solutions (3.00wt%) became smaller and gave higher cooling ability.
