The microchannel heat sink provides an efficient method to solve thermal control problems of the aviation electronic components. The experiment of single-phaseflow and forced convective heat transfer was carried out with FC-72 which was agood prospective electronic cooling fluid. Four rectangular microchannel heat sinks were used which had different structural parameters. The influences of liquid velocity, supercooling temperature and microchannel structures were analyzed. The correlations of single-phase flow resistance and forced convective heat transfer were given, and the uncertainty for experiment data was evaluated. The results show that the single-phase forced convective heat transfer characteristic of FC-72, flowing in rectangular microchannel heat sinks, can satisfy the heat dissipation requirements of middle or high flux for electronic devices.
