摘　　要：针对电源车车厢内柴油发电机组局部散热效果不好的问题,使用基于近似代理模型的数值分析方法对车厢隔板上轴流风机的位置进行了优化,得到车厢内散热效果最好时隔板上轴流风机的位置,并通过CFD仿真计算对利用近似代理模型计算得到的结果进行了验证,可以发现,增加轴流风机后车厢内柴油发电机组局部过热的情况得到有效控制,车厢内发热部件的总热流通量增加了5.37%。Aiming at the heat dissipation problem of diesel generator sets in power vehicle compartment, an ap-proximate surrogate model was used to optimize the position of an axial fan, the results of approximate surrogate model was verified through CFD simulation. It is found that local overheating of diesel generator sets has been effec-tively controlled after increased the axial fan, total heat flux of heating elements inside the vehicle compartment in-creased by 5 . 37%.
