一种适用于空间红外传感器的低温冷源———紧凑式微型同轴脉冲管制冷机

A COLD SOURCE FOR SPACE APPLICATION OF INFRARED SENSORS ——COMPACT CO AXIAL MINIATURE PULSE TUBE COOLER

由于低温端没有运动活塞，脉冲管制冷机近年来得到迅速发展。它结构简单，可靠性和工作寿命高，特别是冷头振动和被冷却元件的抗电磁干扰大大减少，具有不可替代的优越性，是空间微型低温制冷技术的一个重大进步。文中简述脉冲管制冷机用于空间红外传感器需要解决的问题。

The pulse tube cooler has been developped rapidly in recent years because it has no moving piston in the low temperature region. This means that there is no friction, no wear and essentially no vibration, so the low temperature parts have an infinite lifetime. This cryogenic cooler has promising application potential in the cooling of infrared devices and sensors for space application. Detail works and recent developments on the co axial miniature pulse tube cooler made in Cryogenic Laboratory have been presented in the paper.
