Abstract

We developed a facile measurement method of capillary condensation speed of water on nanopillars. The results show a significant enhancement of the condensation speed in nanospace compared to the bulk space. This phenomenon is utilized to achieve a novel "extended-nano heat pipe device", in which a non-electric cooling is expected to be realized. Our findings demonstrate a significantly high speed condensation (3 times) in nanospace for the first time and this specific property is adopted for realizing high-performance cooling devices.
