| 英文摘要 | The use of double-inlet mode in the pulse tube cooler opens up a possibility of dc flow circulating around the regenerator and the pulse tube. the dc flow sometimes deteriorates the performance of the cryocooler because such a steady flow adds an unwanted thermal load to the cold heat exchanger. it seems that this problem is still not well solved although a lot of effort has been made. here we introduce a membrane-barrier method for dc flow suppression in double-inlet pulse tube coolers. an elastic membrane is installed between the pulse tube cooler inlet and the double-inlet valve to break the closed-loop flow path of dc flow. the membrane is acoustically transparent, but would block the dc flow completely. thus the dc flow is thoroughly suppressed and the merit of double-inlet mode is remained. with this method, a temperature reduction of tens of kelvin was obtained in our single-stage pulse tube cooler and the lowest temperature reached 29.8 k.
