Abstract    The Performance of electric vehicle IGPT Pin fin heat sink can be measured by the temperature field and the 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 optimized combination. The relationship between pressure drop of the water inlet, outlet and pin fin parameters was analyzed and calculated. It was respectively analyzed that pressure drop effect on different parameters of 9 groups pin fin heat sink structure project respectively by using the orthogonal design thought. Among the pressure drop curves of 9 schemes, results in scheme 1、5、6、9 were moderate and were in favor of improvement of comprehensive property of heat sink. It was obtained that optimum structure parameters combined of pin fin heat sink of the pressure drop of moderate through the study of the influence of the main parameters of pressure drop. According to the optimum structure parameters, experimental cooling system platform was set up and experiment had been carried on. The optimum structure product of electric vehicle IGPT Pin fin heat sink was produced
