摘要
提高运行频率可以增大功率密度,从而在维持效率一定的情况下有效减小制冷机的体积和重量.本文针对一台工作在100 Hz以上频率的气动斯特林制冷机开展了实验研究.实验表明,在一台商用线性压缩机驱动下,该制冷机可获得77.1 K的最低无负荷制冷温度,当工作在105 Hz,充气压力2.50 MPa时,可在100.0 K提供0.52 W制冷量.
Increasing frequency can improve the power density in a cryocooler thereby can significantly reduce the volume and weight of the system while maintaining comparable efficiency.In this paper,experimental study on a pneumatically driven Stirling cryocooler operating above 100 Hz was carried out.It's shown that a no-load temperature of 77.1 K can be obtained driven by a commercial linear compressor,and a net refrigeration power of 0.52 W was gained at 100.0 K,while the frequency was 105 Hz and the charging pressure was 2.50 MPa.
