Summary

The use of double-inlet mode in the pulse tube cooler opens up a possibility of direct current gas flow circulating around the regenerator and pulse tube. Numerical analysis shows that effects of direct current flow in a single-stage pulse tube cooler are different in some aspects from that in a 4 K pulse tube cooler. For highest cooler efficiency, direct current flow should be compensated to a small value. Dual valves with reversed asymmetric geometries were used for the double-inlet bypass to control the direct curent flow.
