脉冲管制冷系统采用独特的多级相移机制和新颖的压缩机技术，可在4 K、40 K和80 K条件下制冷。IGC-APD在脉管制冷机系统上的发展主要集中在制冷量、温度稳定性、性能可重复性以及整个制冷系统的长寿命等方面。目标是为MRI和其他应用中的下一代冷却系统提供可靠，高效，无振动和长寿命的冷冻冷却器。介绍了用于核磁共振成像冷却的两级脉冲管制冷机及其性能特点。
Pulse tube refrigeration systems have been developed by using unique multiple stage phase shift mechanism and novel compressor technology to produce refrigeration at 4 K, 40 K and 80 K. The developments in IGC-APD on the pulse tube Cryocooler systems have focused primarily on refrigeration capacity, temperature stability, performance repeatability, as well as long life of whole refrigeration system. The goal is to provide reliable, efficient, vibration free and long life cryocoolers for next generation cooling system in MRI and other applications. This paper describes the two-stage pulse tube cryocoolers designed for MRI cooling and their performance characteristics.
