Abstract

A thermoacoustic converter includes a heater, a cooler, and a thermal storage device. The heater includes a first acoustic wave passage and a high-temperature passage for a first fluid. The cooler includes a second acoustic wave passage and a low-temperature passage for a second fluid. The thermal storage device includes an intermediate acoustic wave passage fluidly connecting between the first acoustic wave passage and the second acoustic wave passage. At least one of the high-temperature passage and the low-temperature passage is defined as a specified passage, and at least one of the first fluid or the second fluid is defined as a specified fluid. The specified passage has a near position close to the thermal storage device, and a far position far from the thermal storage device. The specified passage is configured to allow the specified fluid to flow from the near position to the far position.
