Thermal Performance Analysis of a Pulse Tube Refrigerator with Fine Polyester Fibrous Material Filled Regenerator
摘要
Abstract
As the key component of regenerative cryocooler, regenerator and its filled material has great influence on thermal performance of the whole machine. Fine fibrous Polyester was selected as new material filled for regenerator, and experimental research was taken on a single-stage pulse tube cryocooler. The microstructure and physical parameters of the fibrous material were taken. Based on helium-3 charging pressures respectively of 3.5MPa /3.0MPa /2.8MPa /2.5MPa /2.0MPa /1.5MPa, the thermal performances of temperature dropping, working frequency and cooling are collected. The lowest refrigeration temperature, the optimum working frequency, maximum cooling capacity and the maximum percent of Carnot efficiency are obtained and analyzed. The charging air pressure had a profound effect on the thermal performance of the pulse tube cryocooler while the operating frequency played a slightly effect on it. The maximum percent of Carnot efficiency 9.46%@170K/10.06W/77W, the maximum cooling capacity 5.47W@120K/2.5MPa, 12.02W@150K/3.0MPa, 16.49W@170K/3.0MPa, and the lowest refrigeration temperature 96.4K are obtained in the experiment.关键词
