Abstract
Numerical analysis and experiment were performed to study the effects of the middle-bypass valve on the performance of multi-bypass pulse tube refrigerators (MPTR). Numerical predictions reveal the energy transportation and two refrigeration processes occurring in MPTR. The compared results verified that the multi-bypass version improved the performance of the refrigerator in a low temperature range. A lowest temperature of 23.8K was obtained with the MPTR of one middle-bypass tube. A MPTR of two middle-bypass tubes was first constructed and reached a temperature of 24K.
