Abstract
In order that an object can be warmed through the use of thermoacoustic effect, the acoustic heating apparatus includes a first stacksandwiched between a high-temperature-side heat exchangerand a low-temperature input-side heat exchangerin a first tube portionand a second stacksandwiched between a low-temperature-side heat exchangerand a high-temperature output-side heat exchangerin a second tube portion. A standing wave and a traveling wave are generated through self excitation in the first tube portionby cooling the low-temperature input-side heat exchangerto minus 20° C. to 60° C. A temperature gradient is generated in the second stackby propagating the resulting standing wave and the traveling wave to the second tube portion, and high-temperature heat is output due to this temperature gradient from the high-temperature output-side heat exchangerdisposed on the second stackside.
