摘要

在太空中实现低温有三种基本选择:辐射冷却、冷冻剂冷却和机械冷却器。在温度、长寿命和低质量方面，辐射和冷冻选择都可能无法满足未来空间任务的高要求。欧空局目前正在开发的机械冷却器可以克服这些主要问题中的几个，因此与目前的低温冷却设计相比，在整个航天器配置中提供了更大的灵活性。

Mechanical coolers - An option for space cryogenic cooling applications

There are three basic options for achieving cryogenic temperatures in space: radiative cooling, cryogen cooling, and mechanical coolers. Both the radiative and cryogen options can fail to meet the highly-demanding requirements for future space missions in terms of temperature, long life and low mass. The mechanical coolers that ESA is currently developing can overcome several of these major problems, thereby providing much greater flexibility in overall spacecraft configuration compared with current cryogenic cooling designs.

期刊介绍： The ESA Bulletin is ESA’s flagship magazine, published four times a year, describing ESA"s work for a general audience i.e., the space-interested public, stakeholders and decision-makers. It contains an attractive, highly readable mix of informative and in-depth articles, news items and technical project updates.
