通过大量的实验研究了蒸发器内气液分布、反重力工作高度、启动热载荷的大小、热沉温度等因素对启动的影响, 描述并分析了4种不同蒸发器内气液分布情况下的启动现象, 给出了系统温度变化曲线图, 分析了启动的难易程度. 根据实验数据得出结论: (ⅰ) 对于液体干道内充满液体的启动情况, 储液器温度上升的主要原因并不是漏热, 而是回路压力升高所致. (ⅱ) 热载荷大有利于启动. (ⅲ) 未完全绝热时小热载荷下热沉温度不影响启动. (ⅳ) 环路热管在反重力情况下启动时, 当蒸汽槽道存在蒸汽时, 所需启动时间、启动温升增大; 而蒸汽槽道充满液体时, 所需时间、过热度和启动温升都减少. 实验还观察到了反重力启动时呈现两种启动方式的特别现象.
A large number of experiments were carried out to study the influence of gas-liquid distribution, anti-gravity working height, start-up thermal load and heat-sink temperature on the start-up of the evaporator. The gas-liquid distribution in the four different evaporators Starting phenomenon, gives the temperature curve of the system, and analyzes the difficulty of start-up.According to the experimental data, it is concluded that: (i) The main reason for the rise of the accumulator temperature for the start-up of the liquid trunk filled with liquid is not (Ii) The heat load is large enough to start up (iii) The heat sink temperature does not affect the start-up under the condition of incomplete thermal insulation (ⅳ) Under start-up, when the steam channel has steam, the required start-up time increases the start-up temperature rise, while the time, superheat and start-up temperature rise when the steam channel is full of liquid decrease.The experiment also observes the antigravity Start showing two special ways to start.
