Abstract: I used SolidWorks, a three-dimensional modeling software, and FloWorks, a fluid dynamics analysis tool, to simulate oil flow and heat transfer in a heat sink structure attached to three insulated gate bipolar transistors. My objective was to estimate the cooling properties of the oil-cooled heat sink during a range of operating conditions. I calculated steady state temperatures of the heat sink and plotted heat contours on its surface. I also calculated the temperature, pressure, and velocity of the oil as it flowed through the heat sink.
