Highlights

?Design based on unit originally developed for NASA and higher capacity unit for ESA.

?The unit is in a split configuration with the cold head separated from the compressor.

?Cold head arranged in U shape with inertance coil in plenum on warm flange.

?This unit provides a compact system for many actively cooled instruments.

Abstract

This paper describes the expanded performance range of the Lockheed Martin Mini cryocooler thermal mechanical unit (TMU). The design is based on the standard unit originally developed for NASA and a higher capacity developed for ESA. These higher capacity Mini units are in a split configuration with the cold head separated from the compressor.

The TMU provides cooling over a wide range of temperatures with a weight of 1.9?kg including the 1.4?kg compressor and the 0.45?kg cold head. The unit provides for 3.5?W cooling at 105?K and approximately 7?W cooling at 150?K for 293?K reject temperature with 60?W of input power.

抽象

本文介绍了洛克希德Martin Mini Drococooler热机械单元（TMU）的扩展性能范围。该设计基于最初为NASA开发的标准单元和为ESA开发的高容量。这些较高的容量迷你单位处于分开配置，冷盖与压缩机分开。 TMU提供冷却宽范围的温度，重量为1.9 kg，包括1.4 kg压缩机和0.45Ωkg冷头。该装置在105℃下冷却为3.5？k和大约7？W以150Ω·k冷却293Ω·k抑制温度，输入功率为60？W. ]]>
