低温制冷
作为低温设备方面的专家，液化空气公司取得了航天器上从未有过的成就！我们为国际空间站设计了MELFI涡轮发动机，该发动机将生物样品冷却至-80℃，已经运行了10年。这是一个相当大的成就，当你记住它只打算运行两年！
We fitted out Planck and Herschel, the most complex satellites ever produced in Europe. We developed and qualified a dilution refrigerator at 0.1 Kelvin for Planck, which later produced a map of the universe's cosmic background microwave radiation. We produced a huge helium tank to cool the powerful Herschel telescope. Since then, Herschel has produced results that explain how the stars were born. One of our biggest challenges with these satellites was the absolute necessity to avoid leaks, which required high-precision welding work.
液化空气公司也在开发一种创新的脉冲管冷却技术。对于设备空间有限的卫星来说，主动冷却技术是最合适的。
Did you know? The Planck and Herschel telescope's detectors are cooled to a temperature close to absolute zero, allowing it to scan regions of space where temperatures don't exceed 3 Kelvin.
