Abstract The present study has been studied on a thermal and flow characteristic of the microchannel waterblock with flow distributions in each channels. Results of a numerical analysis using the CFX-11 are compared with results of an experiment. Numerical analysis and experiment are conducted under an input power of 150W, inlet temperature of 20℃ and mass flow rates of 0.7~2.0kg/min. Base temperature and pressure drop are investigated with standard deviations of mass flow rates in each channels of samples. The flow distribution and j/f factor of the sample 4 is increased by about 65.7% and 42.6%, compared to that of the reference model sample 3.
