Abstract:

In order to improve the vehicle radiator capacity and keep vehicle reliable, three new improvement schemes were proposed on the foundation of former research. A 3D model based on the drawing from manufactures was set up. Heat exchange model was used as substitute for radiator module. Each improved model was simulated in virtual tunnel with commercial CFD software. These schemes were assessed based on the simulations. The results show that all of three schemes could enhance radiator performance. Addition of air exits near muffler has the best effect. Compared with original model, the intercooler, water radiator and oil radiator of the improved schemes could lower the thermal fluid outlet temperature by 14.48%, 1.39% and 2.28%, respectively.

Key words: vehicle engineering, engine cabin, radiator, numerical analysis, heat exchange
