摘要
针对不同充液率的不锈钢-水重力热管进行实验研究,对比分析倾角对重力热管携带极限的影响;在冷却水流量不变的情况下,测量不同加热温度下重力热管轴向壁面测点温度和冷却水进出口温度,观察重力热管发生携带极限时壁面测点温度的变化情况;对比分析不同倾角下,重力热管携带极限实验值与理论值的区别。结果表明:不同倾角下,充液率为35%的重力热管在给定实验条件下出现携带极限;携带极限实验值随倾角的增大而减小,当倾角为75°时,实验值与理论值最为吻合,其余倾角下,两者之间最大误差为14%。
An experimental study on the stainless steel-water gravity heat pipes with different filling rates is carried out,and the effect of the inclination angle on the carrying limit of the gravity heat pipe is comparatively analyzed.Under the condition of constant cooling water flow,the temperature of the measuring point on the axial wall of the gravity heat pipe and the temperature of the cooling water inlet and outlet under different heating temperatures were measured,and the changes in the temperature of the measuring point on the wall when the gravity heat pipe had a carrying limit were observedand analyzed.The difference between the limit experimental value and the theoretical value is comparatively analyzed under different inclination angles.The results show that under different inclination angles,the gravity heat pipe with a liquid filling rate of 35%has a carrying limit under given experimental conditions,and the carrying limit experimental value decreases with the increasing of the inclination angle.When the inclination angle is 75°,the experimental value is consistent with the theoretical value.At other inclination angles,the maximum error between the two is 14%.
