振荡源结构对静止式气波制冷机振荡特性影响的研究

Research on Oscillation Character of the Static Gas Wave Refrigerator With Different Structure of Oscillator

对振荡源分别为反馈管和共鸣器时机器的振荡特性进行了研究,结果表明,当振荡源为反馈管时,一般振荡频率仅与反馈管管长有关,随着反馈管管长的减小,振荡频率将增大;当振荡源为共鸣器时,对于一定结构的静止式气波制冷机,在其运行过程中出现了低频和高频两种稳定的振荡状态:要得到高频振荡,采用共鸣器作为振荡源更好。

This paper analyses oscillation character of the Static Gas Wave Refrigerator when its oscillators are interline and resonator respectively Results showed that the oscillation frequency only depends on the length of interline and both of them are inverse proportion when interline as oscillator. When oscillator is resonator two kinds of stable oscillations occur in the running refrigerator that are low frequency oscillation and high frequency oscillation and the resonator is better than the interline in order to obtain high frequency oscillation.
