| Abstract: | Based on the principle of thermoacoustic refrigeration,an inexpensive thermoacoustic refrigeration device was designed utilizing self-made stack and adopting common material and instrument.Experimental results showed that temperature decreased 13 ℃ in the resonant tube and temperature difference of 25 ℃ in the stack could be reached in 200 s,taking air as working medium without any other cooling measures in the system. |
