Description
In order to design a high efficient and high-performance pulse tube cryocooler the appropriate size of the cold finger must be found. This study aims to find the relationship between the size and performance of the high frequency miniature pulse tube cryocooler by combining experiment and numerical simulation. The experiments are carried out by changing two aspect: diameter and length of the cold finger. All the experiments are conducted by using coaxial pulse tube. The optimal results of each experiment are compared to find the rule. The experimental results show that the increasing diameter and the decreasing length of pulse tube will improve both the cooling capacity and the optimal frequency.
