Abstract
A new single-stage coaxial micro pulse tube cryocooler has been developed by Technical Institute of Physics and Chemistry, CAS. With the characteristics of long-life and low-mass, it could serve for infrared detectors in space and non-space applications. Driven by a high efficiency and lightweight linear compressor, it has a small cold finger with a diameter of 8 mm, and works at 175 Hz. Inertance tube and a reservoir is used as its phase shifter. At a reject temperature of 283 K, it can lift 0.79 W at 150 K with 10 W electrical input. This paper describes the key parameters of components, and presents test data in several working conditions of this pulse tube cryocooler in detail.
