高速动车组污物箱保温性能探究

Exploration in the Thermal Insulation Performance of the Sewage Tank for High Speed Multiple Units

对高速动车组污物箱在低温试验室内进行了温度控制以及保温性能试验,并将试验结果和模拟计算结果进行了对比。根据物理与数学传热模型分析了外部空气流动速度对污物箱保温性能的影响,为污物箱保温设计提出了建议。

The temperature control and thermal insulation performance test are made on the sewage tank for high speed multiple units in the low temperature laboratory.The test result and the simulation calculation result are compared.On the basis of the physical and mathematical heat transfer models,the effect of the outside air flowing speed on the thermal insulation performance of the sewage tank is analyzed,and suggestions are given on the thermal insulation design of the sewage tank.
