Description
Compressor is the key component of pulse tube cryocooler. It introduces the structure of a linear vibration compressors specifically designed for pulse tube cryocoolers. The paper delves deeply into the impact of compressors on four key aspects: support systems, control systems, compressor efficiency, and vibration and noise reduction. Based on the findings, a compressor weighing 160 grams has been developed, capable of delivering an output power of up to 30W. Furthermore, a micropulse tube cryocooler, coupled with this compressor, operates at a frequency of 152 Hz and provides a cooling capacity of 1.14W with a input power of 10W and a temperature of 150K. Leveraging the design of this compressor, various models have been built and have already undergone mass production for practical applications.
