| 摘 要： | 提出了一种新的防止辐射器冻结的方法——辐射器低温循环系统方法,并对该系统进行了数值模拟。结果表明:辐射器内工质的流动对辐射器的温度分布有明显的改善作用;辐射器节点间的温差随回路中工质流速的增加而明显降低;回路中工质存在最佳流速,当超过该值时对辐射器的温度分布已无明显作用。

| Abstract: | A new method using cryogenic loop system was presented to prevent radiator on docked manned spacecraft from being frozen.The numerical analysis shows that the temperature field of the radiator gets uniform apparently when the working fluid flows.Temperature difference of the radiator reduces with the increasing of flow rate.An optimum rate exists.It is a simple and feasible method for preventing space radiator from being frozen. |
