摘要
针对某特种车辆由传统的燃油动力系统改为混合动力系统的设计要求和热源部件的工作温度特点,设计了具有高、低温双循环回路的冷却系统,将高温热源部件和低温热源部件分开,增大了高温循环回路中冷却介质的温度,提高了冷却系统的散热效率.采用计算机辅助设计对冷却系统和关键部件的热力学参数进行了优化设计,计算结果与所选风扇的性能试验数据对比表明:冷却系统设计方案满足车辆动力系统改型后的散热要求.
Based on the design requirements and the operation temperature characteristics of the thermal source components of a vehicle whose conventional oil burning power system has been changed into one of hybrid system, and a cooling system having high and low temperature circulation loops is designed. The radiating heat efficiency of the cooling system is improved as the high temperature source and the low temperature source components are separated and the operation temperature of the cooling medium of the high temperature circulation loop is heightened. Through CAD, the cooling system parameters and the main component parameters are optimized. The design results are compared with the experimental performance data of the fan selected. It is indicated from the results that the design project can satisfy the requirements of the radiating heat of the vehicle whose power system has been remodeled.
