Summary

Through analyzing phase relation between pressures and flow characteristics of double-inlet and multi-bypass, mechanism of double-inlet to lower the temperature of pulse tube refrigerator is proposed. Then another proposal is put forward to replace the low temperature multi-bypass valve, which is another double-inlet valve at room temperature and a small tube prolonging to the low temperature part of pulse tube. Through experiment, this multi-double-inlet version proves effective to lower the refrigeration temperature. Test acquires a lowest temperature of 37 K with two double inlet valves and 50 K with one double inlet valve. The concept of low temperature double-inlet is proposed here for the first time.
