摘要
针对混合动力车辆的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,增大了高温冷却回路中冷却介质的温度,提高了冷却系统的散热效率。对散热器的热力学参数进行了设计计算,计算结果与所选风扇的性能试验数据对比表明:该双层冷却循环系统满足混合动力车辆的散热要求。
Based on the characteristics of heat-source parts/ working temperature of the hybrid vehicles, a cooling system having high and low temperature circulation loops is designed, 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 hybrid vehicle.
