| 摘 要： | 空间核反应堆是空间核电源和核推进的研究基础,大功率核反应堆的体积和质量一直是限制航空航天设计的重要因素。针对这一问题,本文对MW级空间核反应堆系统热管式辐射散热器进行建模和分析,建立热管式辐射散热器的热阻模型,利用穷举法和遗传算法在给定工况下探讨裸碳纤维翅片长度Lf和厚度δf、冷却剂质量流量m、辐射散热器入口温度Tf1对散热器质量M的影响。结果表明,当Tf1=800 K、Lf=5 cm、δf=0.16 mm、m=9 kg/s时,M达到最优,为906.593 kg,优化了0.63%的系统质量。

| Abstract: | Space nuclear reactor is the research foundation of space nuclear power and nuclear propulsion. The volume and mass of high-power nuclear reactor are always the important factors limiting the aerospace design. In view of this problem, the heat pipe radiation radiator of MW space nuclear reactor system was modeled and analyzed, and the thermal resistance model of the heat pipe radiation radiator was established in this study. The effect of the lengthLf and thickness δf of the bare carbon fiber fin, the mass flow m of the coolant, the inlet temperatureTf1 of the radiation radiator on the mass M of the radiation radiator was discussed under the given conditions by the exhaustive method and genetic algorithm. The results show that whenTf1 is 800 K, Lf is 5 cm,δf is 0.16 mm, and m is 9 kg/s, M is the best. At this time, M is 906.593 kg, and 0.63% of the system mass is optimized. |
