Description

In order to have a more compact structure for the applications, for general design of the co-axial pulse tube cryocoolers (CPTCs), the pulse tube and regenerator share a thin stainless steel wall. In former theoretical analysis, this wall is considered to be adiabatic and few research pays attention to the thermal-coupling effect between the pulse tube and regenerator in CPTCs. In this research, the influence of the thermal-coupling is studied based on the experimental researches with a U-type pulse tube cryocooler firstly. In the experimental researches, the thermal link is considered to simulate the thermal-coupling between the pulse tube and regenerator. Based on our experimental researches, the thermal-coupling between the pulse tube and regenerator benefits for the performance of the PTCs. Furthermore, a simple analysis is introduced to explain the performance increase.
