摘要: Generally, a compressor together with rotary valve system generates the pressure oscillation in GM-type cryocoolers. The timing of valve, which is one key operating parameters for cryocoolers, determines relationship between intake and exhaust processes. A systematic investigation effects on cooling performance two-stage 4 K pulse tube cooler (PTC) reported. experiments show that optimization can considerably improve both stages. For same PTC, comparison operation different compressors various input powers ranging from 0.5 to 6.0 kW also presented.
