abstract
2016 TRF We report the design, fabrication and characterization of a novel nanoporous membrane evaporation device to address ultrahigh heat fluxes in advanced electronics. Our design leverages high capillary pressures (~500 kPa) generated by a liquid wetting 130 nm diameter pores of an ultra-thin (600 nm) silicon membrane, suspended over a microfluidic supply network. The device was microfabricated in silicon and tested using methanol as the working fluid. We demonstrated a heat dissipation over 600 W/cm2 with a heat transfer coefficient more than 15 W/cm2K, which suggests this approach is promising as a high flux thermal management strategy.
