Influence of Front End Structure on Vehicle Cooling Performance

摘要:

为研究汽车前端冷却部件结构对冷却性能的影响，以某一简化车型为研究对象，分别对其格栅、风扇、风扇罩及冷却模块相对位置进行了数值研究.计算采用定常雷诺时均纳维斯托克斯方程.针对数值计算结果，通过对冷却参数等数据的分析比较，归纳总结了汽车前端结构件不同参数的变化对前端进气和汽车冷却性能的影响，得出了适合所研究车型的前端结构件的参数设置，为汽车的实际工程应用提供参考.

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.
