Performance of microchannel heat sink combined with jet impingement for high heat flux density cooling was simulated with numerical method. To compare performance of sinks with different dimensions, an optimization method was developed whose objective was temperature of heating surface with constraint condition of pumping power. The factors of heat sink';s performance such as depth and width of channel, depth of nozzle were analyzed and optimized using this method. The results indicated that the heat sink had optimal dimensions which had relation to pumping power. It was also proved that the heat sink had remarkable cooling capacity, while the temperature was uniform in heating surface.
