| Outline of Final Research Achievements |
The liquid cooling systems utilizing the latent heat transportation during nucleate boiling are able to realize innovative performance for the cooling of semiconductors of electronic devices operated at high heat generation density. The increase of critical heat flux, the reduction of surface temperature, the reduction of surface temperature overshoot at the boiling incipience and the prevention of incondensable gas are fundamental requirements for the development of high-performance cooling systems by the application of boiling phenomena.
Immiscible liquid mixtures can meet the all requirements and the experiments on nucleate pool boiling were conducted to investigate their fundamental heat transfer characteristics. By the subcooling of liquids due to the excessive compression by the vapor of components and the preferential generation of vapor from the more-volatile liquid, most of the above requirements were satisfied.
