摘　　要：高效紧凑化是动力装备发展的重要趋势,优化冷却系统各部件的能量与体积,以破解传统设计方法存在反复人工迭代以及局部优化的难题,是动力装置一体化设计的核心之一.因此提出基于参数化方法的双目标优化设计,针对先进动力车辆冷却系统热耗与体积,建立能量传递、体积映射及耦合模型,利用NSGA-Ⅱ算法,快速求解功耗与体积权衡下的Pareto最优解集,揭示可在相对最优的部件结构参数与系统运行参数下的物质流、能量流、传热与压降对系统体积分布的影响规律.所得结果表明,串联、并联、混联的双泵双循环冷却系统布置方式在不同的体积和功耗要求下有各自的适配区间,600 kW发动机所对应的工况散热压力下,相对于传统设计方法,本方法可减少体积6.47%、降低功耗1.67%.High efficiency and compactness are the important trends in the development of power equipment.And the core task is to realize the optimal design of energy and volume for the component cooling system of power plant to overcome the problems of repeated manual iteration and local optimization in the traditional design method.In this paper,an integrated bi-objective optimization design method was proposed based on parametric method for the heat consumption and volume of advanced power vehicle cooling system.Firstly,a model was established to carry out energy transfer,volume mapping and coupling for the each component of the cooling system.Then,taking the NSGA-II heuristic algorithm to quickly obtain the Pareto non-inferior solution set under different heat dissipation and volume trade-off objectives.Finally,it was arranged to reveal the influence of the material flow,energy flow,heat transfer and pressure drop of each component on volume distribution of the system under the condition with corresponding optimal structural and operating parameters.The results show that every arrangement of double-pump double-circulation cooling system,the series,parallel and hybrid,can all take its own adaptation range under different volume and power consumption requirements.Compared with the traditional design method,the proposed method can reduce the volume of power equipment by 6.47%and reduce the power consumption by 1.67%under heat dissipation pressure of 600 kW engine working conditions.
