Description
Two-cold-finger pulse tube cryocooler is used to meet the demand of multi-temperature refrigeration. It contains a linear compressor and two cold fingers. A series of cold fingers are tested respectively in this paper first. Then, any two of these cold fingers are chosen to connect the compressor and their performance are tested. Finally, the coupling results are compared. The results show that the size of pulse tube refrigerator, cooling capacity of cold finger and input power of compressor have influence on the gas distribution and phase position. In this study, refrigerating efficiency and coupling efficiency are used to evaluate it’s practicability.
