Abstract

Heat transfer and flow performance of water and galinstan in manifold microchannel heat sinks is analyzed. The three dimensional flow and conjugate heat transfer is numerically simulated for microchannels of two different hydraulic diameters. The heat transfer coefficient, wall temperature variation at the base, and performance factor were analyzed for the same inlet velocity, Reynolds number and pressure drop conditions for water and liquid metal for different heat flux boundary conditions. Due to the short length of microchannels, it was found that performance factor of liquid metal is larger compared to water for all the cases.
