| Abstract: | Cooling water channel model and exhaust channel model for the EGR heat exchanger in car diesel engine are established,and the temperature fields for the models are calculated by CFD simulation respectively.The results show that both the inlet structure of EGR heat exchanger and the fins within the exhaustion pathway can affect temperature field distribution to some extent,where by affecting the heat transfer efficiency of EGR heat exchanger. |
