Résumé

The newly-developed holey optical fiber in photo-communication technology is introduced to the pulse tube cryocooler (PTC), exploring its feasibility as the regenerator. The influences of regenerative materials, as well as the influences of regenerator geometry, frequency, working pressure and input power were analyzed by calculating with a model based on thermoacoustic theory. The results from the simulation demonstrate that compared with the conventional stacked stainless steel screen, the utilization of optical fiber has the potential in increasing the coefficient of performance of a micro-scale PTC, as large as 0.136 at 80 K. Further calculation shows the influence of working parameters on the performance of a micro-scale PTC with the optimized geometries.
