Abstract
One important configuration of a pulse tube refrigerator is the multi-bypass pulse tube refrigerator (MPTR). This paper analyzes the working processes of this PT configuration and presents some experimental results taken using operating frequencies below 5 Hz. The analysis shows that a MPTR is different from a general multi-stage cooler, but works somewhat like a multi-stage cooler to a certain extent. Experimental results are presented and compared to former results. The experiments demonstrate that the multi-bypass channel leads to an improvement in performance, and that the function of the multi-bypass more resembles a double-inlet than the first-stage of a multi-stage cooler.
