为满足某型高功率密度柴油机智能化控制冷却系统的设计需要,构建了高功率密度柴油机与冷却系统的工作过程耦合模型。利用该模型计算了柴油机关键热部件的散热量MAP,并对结果进行了分析。结果表明:一级中冷和二级中冷散热量随环境温度升高而降低;级间中冷散热量随环境温度的升高而升高。应用该方法能够快速掌握高功率密度柴油机的散热规律,为制定智能化控制冷却系统的控制策略提供依据。
In order to meet the design requirements of a kind of high power density diesel engine intelligent control cooling system, a working process coupling model of high power density diesel engine and cooling system was constructed. The model was used to calculate the heat dissipation MAP of the key hot components of diesel engine and the results were analyzed. The results show that the heat dissipation of the first-stage and second-stage intercooling decreases with the increase of the ambient temperature, and the intercooler heat dissipation increases with the increase of the ambient temperature. The method can quickly grasp the cooling rules of high power density diesel engine and provide the basis for making the control strategy of intelligent control cooling system.
