Influence of Front End Structure on Vehicle Cooling Performance

Abstract:

To study the influence of front end structure on vehicle cooling performances, a simplified vehicle was constructed. The grill, cooling fans, fan shroud and cooling module layout of the vehicle were simulated by steady Reynolds Navien Stokes(RANS) Navier Stokes calculation. According to the simulation results the cooling parameters were analyzed. And the influence of changes for front end structure parameters toward front end airflow and cooling performance were summarized. The proper parameter settings suited for the same type vehicles studied in this paper were obtained. The study provides a reference for the vehicle’s engineering application.
