摘要/Abstract

摘要： 深冷环路热管作为深低温区高效两相热传输系统,运行稳定性问题直接决定着热控系统运控性能。本研究采用深冷环路热管系统级瞬态模型,对氖工质深冷环路热管稳定性进行瞬态仿真。模拟研究氖工质深冷环路热管系统压力和运行温度波动现象及原因,分析失稳过程中系统关键部件内部的气液分布特征。结合温度-压降相图分析系统失稳机制,揭示深冷环路热管不同运行工况中出现的稳定运行、振荡衰减、振荡放大和周期振荡四种不同运行状态特征。

Abstract: Cryogenic loop heat pipes(CLHPs), as efficient two-phase heat transfer systems for the cryogenic temperature range, have been widely used in many engineering applications both on the ground and in space. The operational stability of CLHPs directly influenced the performance of the thermal control system. In this study, a system-level transient model was employed to conduct transient simulations on the operational stability of a neon-charged CLHP(Ne-CLHP). The phenomena and causes of pressure and operating temperature oscillations in the Ne-CLHP were simulated and investigated. The gas-liquid distribution characteristics inside the key components of the system during the instability process were analyzed in detail. Combined with the temperature-pressure drop phase diagram, the instability mechanism was examined, which revealed four distinct operating states—stable operation, oscillation attenuation, oscillation amplification, and periodic oscillation—that occurred under different operating conditions of the CLHP.

Key words: cryogenic temperature, loop heat pipe, temperature oscillation, instability, transient model
