摘要： 建立了微重力环境下管肋式空间辐射器传热过程的数学模型，并以单位质量散热量最大和热载体驱动功率最小为优化目标，对管肋式空间辐射器进行了优化分析。采用直接搜索可行方向（ＤＳＦＤ）算法求解了一个多目标、多约束的非线性规划问题，提出了管肋式空间辐射器的整体优化方法，得出了管肋式空间辐射器的优化设计参数。

Abstract: A heat transfer model on a fin tube radiator under micro gravity is established in this paper.The maximum heat discharge per unit mass and the minimum power to drive fluid are adopted as the optimum objects,and the fin tube radiator of aircraft is thus optimally analyzed.The DSFD method is applied to solve a non linear optimum problem with multi objects and multi constraints and the method to optimize the fin tube radiator on the whole is postulated.The optimum designing parameters for the fin tube radiator is provided as a result.
