摘　　要：分流劈距是静止式气波制冷机设计的一个重要参数。通过实验的方法研究了分流劈距对静止式气波制冷机性能的影响。当分流劈距较小时 ,射流发生了切换 ,当分流劈距较大时 ,射流未发生切换。振荡频率几乎不受分流劈距的影响 ,它只是振荡管长的函数。分流劈距的大小对制冷效率有直接的影响 ,随着分流劈距的增大制冷效率逐渐减小。对应不同的操作条件 。The spliter is an important parameter in designing the static gas wave refrigerator. In this research, the influence of the spliter upon character of static gas wave refrigerator was investigated byexperiments. The fluidic occurred to switch when the spliter location was small while the fluidic did not switch when the spliter location was big. The oscillation frequency only was the function of oscillating tube length, not influenced by the spliter. However, the spliter location directly influenced the refrigeration efficiency which decreased when the spliter location increased. Under the distinct operation condition, the spliter location had a most reasonable value accordingly.
