摘要 | To meet the thermal control requirements of the optical system, experimental studies including the start-up, the responses to heat loads and the steady-state heat transfer characteristics of a proposed loop heat pipe (LHP) under different attitudes were carried out. Sintered copper powder porous wick with a mean pore radius of 30~50 μm was applied, and ethylene was the corresponding working fluid. Three attitudes were overall horizontal (attitude A), the evaporator and compensation chamber (CC) placed at an angle of 45° from the horizontal plane with the evaporator above the CC (attitude B), and the evaporator and CC placed at an angle of 45° from the horizontal plane with the CC above the evaporator (attitude C), respectively. Research results indicate that the LHP can start up successfully from the supercritical states at all three attitudes without the assistant of the secondary loop, but with a reverse direction for attitude C. The responses to heat loads of the LHP at attitude C are faster than that at attitude A and B. The LHP operates in a reverse direction with temperature fluctuations, which decreases with the rising heat load at attitude C. The LHP operates normally at attitudes A and B with different variation trends of heat transfer differences with the rising heat load, but the heat transfer temperature differences are less than 15 K under heat loads of 10 W and 20 W at both attitudes, which could fit the application requirements. |
