【Abstract】 The working mechanism of the tandem thermoacoustic refrigerator driven by heat was analyzed.The full - wavelength resonance would be excited in tandem thermoacoustic refrigerators.How to control this second - order resonant mode was discussed. The thermoacoustic conversion in standing - wave and traveling - wave thermoacoustic units would be much more effective than that in conventional standing - wave thermoacoustic engines.The recovery of the expansion power by a standing - wave thermoacoustic unit was studied.更多还原
