Water-cooled heat sinks are investigated both experimentally and theoretically as model systems to simulate the energy and mass transport in devices used for cooling of optoelectronic microsystems. The design of the micro-channel heat sinks results in a decrease of their thermal resistance and of the pressure drop of the coolant allowing an increased heat load of an optoelectronic microsystem such as diode laser.
