摘要
声驱动的热声制冷机是微型低温技术潜在的最佳技术。为适应微型化的要求,将一般的电动扬声器改为电动膜片式声源,并将整个系统网络化,据此提出了一种微型热声制冷机的设计方法,并运用此方法提出了一个具体的高频设计方案:工作频率f=4000Hz;谐振管半径a=0.002m;谐振管长L=0.042m。
Thermoacoustic cooler driving by sound is the optimal project for developing of subminiature cryogenic technology. To adapt the micromation, we change loudspeaker to dynamoelectric sound source. We give the equivalent network of the system, and introduce a design method of the miniature thermoacoustic cooler based on it. A project with high frequency based on the method is put forward that the frequency is 4 000 Hz and the radius of resonance is 0.002 m and the length of resonance is 0.042 m.
