| Abstract: | In this article, a new kind of pulse tube refrigerator with low temperature switch valve and liquid nitrogen precooler is introduced. Theoretical analysis shows that it is a promising alternative of ordinary pulse tube refrigerator. However, experimental results are not good. Qualitative analysis and quantitative computation have been made to find the possible reasons. The experimental and theoretical results are given. |
