【摘要】 低温回路热管在较大热负荷下运行时会出现温度振荡现象。本文通过对一台低温回路热管原理样机进行性能试验,测量了温度振荡的产生范围、产生条件和振荡幅度。通过计算低温回路热管内气、液分配,认为温度振荡是由于二次回路工作不稳定所致,并提出通过改变二次回路的进液方式可以避免温度振荡现象的发生。更多还原

【Abstract】 Temperature oscillation occurs in operation of a cryogenic loop heat pipe(CLHP) under large heat load.Experiments are carried out on a CLHP prototype to identify the effective area,the operation conditions and the amplitudes of the temperature oscillation. Through calculation of the distribution of the gas and liquid inside the CLHP,it is considered that the temperature oscillation is due to the unstable operation of the secondary loop,and it is proposed that the temperature oscillation may be eliminated through alternating the liquid feed method of the secondary loop.更多还原
