Abstract
There is provided a thermoacoustic devicewhich has in a loop tube, a first stackbetween a first high-temperature side heat exchangerand a first low-temperature side heat exchanger, and a second stackprovided between a second high-temperature side heat exchangerand a second low-temperature side heat exchanger, so that heat at the first stack side is prevented from being transported to the second stack side even when a large acoustic wave is generated in the tube. In the device, self-excited standing and traveling waves are generated by heating the first high-temperature side heat exchanger, and by the standing and traveling waves, the second low-temperature side heat exchangeris cooled. a piezoelectric filmis provided to suppress an acoustic streaming and/or a direct-current type flow of a working fluid.
