摘要
为了实现汽车发动机冷却系统性能最优化设计,该文用经验参数方法设计了某款车型的散热器,同时建立了该车型发动机冷却系统风侧准三维模型和水侧一维模型,进行了仿真分析,对散热器方案进行了设计改善,并进行了试验验证。新方案散热器匹配该车后,低速爬坡的平衡水温提高了16.3℃,同时满足115℃的设计限值要求,散热器质量降低了1.2 kg。验证了基于仿真模型的散热器设计方法的正确性,为今后汽车的散热器设计开发提供了可借鉴的方法。
In order to realize the optimal design of automobile engine cooling system performance, this paper designs the radiator of a certain vehicle type by empirical parameter method, establishes the quasi-three-dimensional model on the air side and the one-dimensional model on the water side of the engine cooling system of this vehicle type at the same time, carries out simulation analysis, improves the design of the radiator scheme, and carries out experimental verification. After matching the radiator of the new scheme with the vehicle, the equilibrium water temperature for low-speed climbing is increased by 16.3 ℃,the design limit of 115 ℃ is met at the same time, and the mass of the radiator is reduced by 1.2 kg. The correctness of the radiator design method based on the simulation model is verified, which provides a reference method for the design and development of automobile radiators in the future.
