Abstract
A thermoacoustic engine includes first and second stacks disposed in parallel in a looped tube and a heat storage unit disposed in the looped tube. A circuit length between a center of the first stack and a center of the heat storage unit is equal to a circuit length between a center of the second stack and the center of the heat storage unit. A first acoustic circuit including the first stack and the heat storage unit has a circuit length which is equal to a circuit length of a second acoustic circuit including the second stack and the heat storage unit.
