摘要
本文基于某前置后驱车型整车开发,运用流体力学方法对该车型发动机舱进行流场分析、温度场分析,并根据分析结果提出优化发动机舱热管理的措施。通过仿真分析及实车验证结果表明,增加散热器和中冷器导风板、优化前格栅开口、增加下盖板导风板等热管理优化措施明显提高了冷却系统进风量、降低了变速器表面受热温度,成功解决了某前置后驱车型的热害问题。
Based on the development of a front-rear-drive vehicle,this paper uses fluid mechanics to analyze the flow field and temperature field of the engine compartment of a vehicle.According to the analysis results,measures to optimize the thermal management of the engine compartment are proposed.Simulation analysis and actual vehicle verification results show that thermal management optimization measures such as adding radiator and intercooler air deflector,optimizing the opening of the front grille,and increasing the lower cover air deflector significantly increase the air intake of the cooling system and reduce the transmission,and the heat damage problem of a front-rear-drive model is successfully solved.
