In subcooled flow boiling of water in a horizontal rectangular channel, microbubble emission boiling occurred at high subcooling of liquid in transition boiling and the heat fluxes increased higher than the critical heat fluxes. The maximum heat flux reached 10MW/m^2 for a channel with 12mm×17mm of cross section at 40K of liquid subcooling and O.5m/s of liquid velocity. For smaller channels with 14mm×5mm, 14mm×3mm, and 14mm×1mm of cross sections, the maximum heat fluxes were 7MW/m^2 that would be more than 7 times of cooling limit of CPU or power 1C of today. Microbubble emission boiling is expected to realize the high heat flux cooling for electronic devices.
