文中对某型动车组电气控制箱散热设计进行验证，在环境温度分别为25、40、55℃条件下进行热仿真，发现高温环境下箱内组件最高温度超过70℃。通过分析进行结构优化后对流换热效果增强，但仍未满足温度要求，进行参数优化，通过单因素试验得出参数取值范围、Plackett-Burman试验筛选参数，采用Box-Behnken设计建立了孔X尺寸x1、孔Y尺寸y1、孔Y位移y2与电源模块最高温度R1的二阶回归响应面模型。通过方差等多种指标验证了模型的准确性，求解响应面模型得出优化参数组合，R1仿真结果降低了25.71℃，与预测值相差0.1℃，证实了模型的有效性，可为其他产品散热结构优化提供一定的参考。
Abstract：This article validates the heat dissipation design of an electrical control box for a certain type of EMU. Thermal simulations were conducted under ambient temperatures of 25 ℃, 40 ℃, and 55 ℃, and it was found that the highest temperature of the components inside the box exceeded 70 ℃ in high-temperature environments. After analyzing and optimizing the structure, the convective heat transfer effect was enhanced, but it still did not meet the temperature requirements. Parameter optimization was carried out, and the parameter value range was obtained through single factor experiments. Plackett-Burman experiments were used to screen parameters. Box Behnken design was used to establish a second-order regression response surface model of hole X size x1, hole Y size y1, hole Y displacement y2, and the highest temperature R1 of the power module. The accuracy of the model was verified through indicators such as variance, and the optimized parameter combination was obtained by solving the response surface model. The simulation results of R1 reduced by 25.71 ℃, which differed from the predicted value by 0.1 ℃, confirming the effectiveness of the model and providing some reference for optimizing the heat dissipation structure of other products.
