摘要
为了研究毛细抽吸两相环回路（ＣＰＬ）运行的稳定性特性，对ＣＰＬ－Ⅲ工程模型系统进行了实验研究。总结了ＣＰＬ系统运行稳定性的各种影响因素，包括蒸发器功率、储液器温度、冷却液温度及蒸发器之间的相互影响等，并且对以上因素进行了理论上定性的解释。增大毛细抽吸力，提高储液器温度、保持储液器温度恒定，降低蒸发器功率、减小蒸发器功率的扰动，降低冷却液温度，使储液器的注入点远离蒸发器等可以提高系统稳定性，两个蒸发器之间的相互作用也对ＣＰＬ系统稳定性有影响。在已有实验数据的基础上，给出了系统运行的稳定区域图，并拟合出了不稳定区域的边界线方程。
In order to predict the stability characteristics of the capillary pumped loop (CPL) system, this paper took experimental investigation on CPL Ⅲ, the capillary pumped loop engineering model system. Influential factors on the stability of CPL operation, such as the power of evaporators, the temperature of the reservoir, the temperature of coolant and the interaction of evaporators etc., have been discussed and summarized. The theoretical qualitative explanation for the factors has been given. Enhancing the cpaillary pumping ability, increasing the reservoir temperature, keeping the reservoir temperature constant, decreasing the evaporator power and the disturber of power, reducing the coolant temperature and keeping the reservoir inlet further away from the evaporator can ameliorate the stability of CPL system. Interaction between two evaporators can also influence stability. A stability range map of the CPL Ⅲ system was developed based on the available experimental data. The stability border equation was also fitted out.
