Abstract
A two-phase microchannel heat sink can be a fluid channel including a bottom wall including a superhydrophilic surface with microstructures and a side wall including a surface that is hydrophobic relative to the superhydrophilic surface of the bottom wall. When heat flux is applied to the fluid channel, a liquid film on the bottom wall is maintained and nucleation of boiling occurs only on the side wall.
