为合理布置风扇以改善发动机舱散热性能,采用三维 CFD 方法,研究了怠速工况下风扇布置对载货汽车发动机舱散热性能的影响。冷却部件采用 IRFN（intercooler, radiator, fan power train cooling module）布置方式。并就冷却风扇与主要部件间距离对散热性能的影响进行了仿真分析,结果表明,风扇和散热器距离越远,对发动机舱散热越有利；风扇与发动机本体之间存在一个最佳距离,使的发动机舱散热最好。

To rationalize the fan layout and improve underhood heat dissipation, we use three-dimensional CFD method to study the influence of fan layout on the heat dissipation of the truck underhood in idling condition. IRFN (intercooler, radiator, fan power train cooling module) layout is adopted for cooling components and the influence of the distance between fan and main components on heat dissipation is simulated and analyzed. The results show that the greater the distance between fan and radiator, the better the heat dissipation is, and there is an optimal distance between fan and engine that makes the best heat dissipation performance.
