A Review on Performance and Evaluation of Modified Regenerator’s Material in Stirling-Type Pulse Tube CryoCooler

This paper presents a comparison and solution of the regenerator’s material of stirling-type pulse tube cryocooler. Here, a method of precisely controlling temperatures using different materials for regenerator in stirling-type pulse tube cryocooler (SPTC) has been studied and compared to a conventional cryosystem. The main aim is to focus on the cooling performance and to suggest best the optimal filling proportion for regenerator of SPTC. The main contribution of this work lies in the comparative study of different regenerator’s material for SPTC. The study shows that the system uses meshes of stainless steel along with Pb for the first stage regenerator and HoCu2, Er3Ni, Pb, and SS meshes in the volume percentage ratio 27:27:27:19 for the second stage regenerator give a good specific heat. This study shall help the policymakers to choose the best criteria, while formulating a newer edition of SPTC.
