1.引言低温致冷器是许多红外系统的重要部分,而且是宇宙空间系统的绝对关键的部分。本文讨论空间红外实验用致冷系统,虽然将着重在空间应用上,但将会看出,讨论的大部分也切合航空和气象实验。本文的目的是讨论可用于冷却空间红外实验设备的各种致冷系统的特性。设计者可借助所提供的
1. Introduction Cryogenic coolers are an important part of many infrared systems and are an absolutely crucial part of the space system. This article discusses the refrigeration system for space infrared experiments, although focusing on space applications, it will be seen that much of the discussion is also in line with aeronautical and meteorological experiments. The purpose of this paper is to discuss the characteristics of various refrigeration systems that can be used to cool space infrared experimental equipment. The designer can use the provided
