针对单储液器环路热管在过载加速度作用下可能出现的温度波动甚至无法运行的问题,基于恒加速度离心机系统,建立了双储液器环路热管(DCCLHP)工作特性实验台,实验研究了双储液器环路热管在重力场稳定运行后再施加过载加速度时的工作特性,分析了不同加热功率、不同加速度大小和方向对其运行性能的影响.结果表明,双储液器环路热管在加速度为7g时仍可达到稳定工作状态,加速度作用导致其稳定运行温度低于地面重力场的温度,且随加热功率和加速度不同,运行温度降低程度不同;加速度方向沿储液器2指向储液器1时其达到稳定状态所需时间比其反方向时更短.实验还观察到了加速度作用下冷凝器出口和液体管线出口温度波动现象.
Aiming at the problem that the single receiver loop heat pipe may fluctuate or not even run under the overload acceleration, a working platform of the double receiver loop heat pipe (DCCLHP) is established based on the constant acceleration centrifuge system. The experimental study The operating characteristics of a dual reservoir loop heat pipe after applying the overload acceleration after the steady operation of the gravitational field are analyzed and the effects of different heating powers, different accelerations and directions on the operating performance are analyzed. The results show that the double reservoir loop The heat pipe can still reach a steady state when the acceleration is 7g. The acceleration causes the stable operating temperature to be lower than the gravitational field. And with the different heating power and acceleration, the operating temperature decreases to a different degree. The acceleration direction follows the direction of the accumulator 2 The time it takes for the accumulator 1 to reach steady state is shorter than in the opposite direction.The experiment also observed the temperature fluctuations at the condenser outlet and the liquid line outlet under acceleration.
