The aim of this study is to investigate the performance and the fluid dynamic behavior of application of proto electric device’s cooling system for high efficient vehicle in severe driving condition in terms of engine and electric devices’ cooling. In this study, optimum layout of extra heat exchanger for electric device cooling has been simulated and analyzed by 3-D thermal flow analytic software, UH3D. In spite of extra cooling system for high efficient vehicle, cooling module layout is being considered as 2 column due to confined engine room and pedestrian’s protection. For this reason, unified heat exchangers with combination of two kinds of engine/electric device and condenser/electric device were studies to find out better solution in terms of cooling performance. As results of 3D analysis, combination of condenser/electric device cooling heat exchanger is considered as the effective way for a vehicle optimum cooling module because of less influence on condenser heat rejection and more heat transfer area for engine cooling system. From further studies, such as the variation of cooling module location and interval between 2 column of cooling module, additional performance improvement for electric device cooling system seems to be achieved.
