Abstract

Based on the analysis of heat transfer and fluid flow in the staged pulse tube, a novel phase-shifter named secondary(minor) orifice was firstly introduced between the reservoir of the final stage pulse tube and the inlet line of the helium compressor, so as to eliminate the anomalous temperature distribution along the pulse tube. The influence of construction and operating parameters on cooling performance of the machine was experimentally studied. Finally a refrigerating temperature as low as 3.0K has been obtained by a two-staged pulse tube refrigerator with the double-orifice configuration.
