Abstract
It is always been a research hotspot to improve the overall efficiency of Stirling pulse tube cryocoolers (SPTCs). The regenerator as the vital component directly determines the performance of SPTCs. Therefore, an approach to improve the overall efficiency is provided by improving the performance of the regenerator. The factors for the influence of the three regenerators structure on the overall efficiency are analyzed and discussed by an 8W@80K SPTC Sage model. The simulation results show the optimal overall efficiency of SPTC with three different regenerators structure varies with the compressor PV power input. Moreover, in terms of the overall efficiency, the smaller the regenerator volume is, the higher overall efficiency will be obtained. Specifically, the overall efficiency of a SPTC with the non-equal (variable and conical) section regenerators is increased by 14.7% and 50% respectively compared with the equal (constant) section regenerator, which theoretically proves the feasibility of this method.
