Research on Properties of Fluid Pressure Drop for Electric Vehicle IGPT Pin Fin Heat Sink

The performance of electric vehicle IGPT pin fin heat sink can be measured by the temperature field and fluid pressure and other parameters. In order to improve the cooling effect of pin fin heat sink, diameter, length and distance of the fin was optimizedin combination. The relationship betweenpressure drop of the water inlet, outlet and pin fin parameters was analyzed and calculated. Pressure drop effect on different parameters of 9 groups of pin fin heat sink structures was analyzed using theorthogonal design. Among the pressure drop curves of 9 schemes, results ofschemes 1,5,6 and9 weremoderate and in favor of improving comprehensive property of heat sink. According to the optimum structure parameters, experimental cooling system platform was set up and experiments were carried on. The optimum structure of electric vehicle IGPT pin fin heat sink was produced.
