发布时间：2018-10-08 11:44
【摘要】：超流氦恒温器是远红外探测器冷却系统的主要设备,气液相分离器则是超流氦恒温器的关键部件,能有效完成超流氦的气液分离,防止泄漏并实现空间液体的综合管理。文中介绍了在空间红外探测中应用较多的多孔塞相分离器的工作原理,描述了多孔塞的流量特性曲线,并对曲线上各工作区域的质量流量与温差(压差)的关系式进行了介绍。文中还对多孔塞的制备工艺进行了分析,并结合国内外研究进展给出了合理选择多孔塞所需要注意的相关参数。
[Abstract]:The superfluid helium thermostat is the main equipment of the far infrared detector cooling system, and the gas-liquid phase separator is the key component of the superfluid helium thermostat. It can effectively complete the gas-liquid separation of superfluid helium, prevent leakage and realize the integrated management of the space liquid. This paper introduces the working principle of the porous plug phase separator which is widely used in the space infrared detection, describes the flow characteristic curve of the porous plug, and introduces the relationship between the mass flow rate of each working area on the curve and the temperature difference (pressure difference). The preparation process of porous plug is also analyzed, and the relevant parameters for reasonable selection of porous plug are given according to the research progress at home and abroad.
