We discussed the stack which is the key device of the thermoacoustic system. We elucidate the stack mechanism to realize further energy conversion efficiency improvement. In this report, the effect of the resonance frequency with the standing-wave thermoacoustic-system and the internal temperature of the stack on the work flow in the stack was experimentally investigated. As a result, regardless of the resonance frequency, heating of the internal temperature of the stack is effective for increasing the amount of the work flow generation.
