چکیده انگلیسی
The development of a high cooling power and high efficiency 4.2Â K two stage G-M cryocooler is critically important given its broad applications in low temperature superconductors, MRI, infrared detector and cryogenic electronics. A high efficiency 1.5Â W/4.2Â K pneumatic-drive G-M cryocooler has recently been designed and developed by ARS. The effect of expansion volume rate and operation conditions on the cooling performance has been experimentally investigated. A typical cooling performance of 1.5Â W/4.2Â K has been achieved, and the minimum temperature of the second stage is 2.46Â K. The steady input power of the compressor at 60Â Hz is 6.8Â kW, while the operation speed of the rotary valve is 30Â rpm. A maximum cooling power of 1.75Â W/4.2Â K has been obtained in test runs.
