摘要
载人航天舱内热环境的调节是一个与航天员工作、生活密切相关的课题,但现有办法消耗能量大,而且散热系统中包含了诸多结构复杂的热交换装置,这对于远离地球能源供给困难的航天环境十分不利.如果能够最大限度地减少耗电,充分利用自然能源且能方便地达到调温的目的,并能营造出一个良好的工作环境,这对于未来航天事业的发展尤其是建立大型空间站等都是十分有意义的事.本文介绍了近年来国际上在航天高技术领域内发展起来的一种新型的热传输系统——毛细抽吸两相循环(CPL)系统的工作原理及其良好的热传输特性和温控特性,指出将CPL原理应用于载人航天舱内热环境调温环节的无动力及噪声型装置的可能性及其重要意义,分析了实现过程中所存在的困难及其对策.
Energy consumed by currently existing thermal control system in manned space cabin is great and a lot of complex heat exchangers are needed. A new heat transmission system, the capillary pumped loop was developed lately. Its working principles, heat transfer performance and temperature regulation were discussed. The possibilities and meanings of application of this non - dynamic temperature regulation system based on CPL theory to the thermal control inside manned space cabin, as well as its difficulties and solutions existed were also discussed.
