摘要
热管理系统在新能源汽车中占据重要地位,其中的水箱集成系统是保证冷却液存储和顺利运输的关键。在热管理模块中选取电驱冷却、电池冷却、电池均热3种模式,通过STAR-CCM+软件对水箱集成系统进行建模仿真,研究系统内部流通及压力损失情况。仿真结果表明,处于电驱冷却、电池冷却与电池均热模式时,最大流速出现在五通阀V3和V4汇流处,数值为3.78 m/s;最大局部压力出现在六通阀V5转弯处,电驱、散热器流道压力差为10 474 Pa;储水箱内最高温度为40℃。
Thermal management system plays an important role in new energy vehicles, and the water tank integrated system in thermal management system is the key to ensure the storage and smooth transportation of coolant. In the thermal management module, three modes of electric drive cooling, battery cooling and battery soaking were selected. The water tank integrated system was modeled and simulated by STAR-CCM+, and the internal flow and pressure loss of the water tank integrated system were obtained. The simulation results showed that when in the electric drive cooling, battery cooling and battery soaking mode, the maximum flow rate appeared at the confluence of the five-way valve V3 and V4, with a size of 3.78 m/s, the maximum local pressure appeared at the V5 turning point of the six-way valve, and the pressure difference between the electric drive and the radiator channel was 10 474 Pa. The maximum temperature in the storage tank was 40 ℃.
