采用微机实时控制脉管制冷机配气装置,可以灵活调节压力波频率和阀门启闭时间比,有可能获得更低的温度,更大的制冷量,使其性能接近G-M制冷机.在脉管制冷机结构参数相同的条件下,二阀与无阀脉管制冷机性能的对比实验表明,通过仔细的时序调节,有阀型脉管制冷机可获得更好的制冷性能. The use of computer real-time control of pulse tube refrigerator gas distribution device, you can flexibly adjust the pressure wave frequency and valve opening and closing time than the possibility of lower temperatures and greater cooling capacity to make its performance close to the GM refrigerator in the vessel A comparison of the performance of two-valve and valveless pulse tube refrigerators under the same conditions of the structural parameters of the chiller shows that the valved pulse tube chiller achieves better cooling performance through careful timing adjustment.
