Abstract
This chapter explores an experimental study on wall temperature distribution of a Stirling-type pulse tube refrigerator. The influences of structural and working parameters on performance of SPTR have been studied, especially on wall temperature distributions of pulse tube and regenerator. It is well known that pulse tube refrigerator is a good alternative to Stirling and G-M refrigerators, because there is no moving part in the cold head. To further improve the performance of Stirling-type pulse tube refrigerator, it is important to study the wall temperature distribution curve of pulse tube and regenerator of SPTR. The wall temperature distribution curve of the regenerator can be regarded as an experimental criterion if the design and cooling capacity of SPTR is the best. At the same time, DC flow from temperature distribution curvecan be validated.
