Abstract :
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 between
pressure 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 the
orthogonal design. Among the pressure drop curves of 9 schemes, results ofschemes 1,5,6 and9 were
moderate 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.
