摘要：针对飞行器设备舱内外耦合热效应问题，采用三维内外耦合防热结构设计软件SDUeegn进行了飞行器设备舱换热数值模拟研究，获得了辐射热流功率、舱体厚度与热源布置位置对设备舱温度分布的影响规律。计算结果表明：随着辐射热流功率的增大，舱体外壳温度越高，舱内仪器温升越明显；随着舱体厚度的增大，舱体外壳温度越低，舱内仪器温升不明显；在不同运行时间内，内部热源与外部辐射热流在耦合热效应中影响程度不同，且热源与其他模块的相对位置与遮挡情况同样会改变舱内耦合热效应情况。在分析规律后提出模拟设备舱优化参数，经测试能达到正常工作温度范围，可为设备舱防热结构的初始外形设计提供数据支撑。 关键词：耦合热效应温度场预测数值模拟模型设计辐射因子飞行器设备舱
