THERMO-ACOUSTIC HEATING DEVICE

Provided is a thermoacoustic heating device capable of effectively utilizing streaming. In this thermoacoustic heating device (10), a prime mover (22) is provided in a first pipeline (11) that forms a loop line, and a heating device (23) is provided in a second pipeline (12) that similarly forms another loop line. The first and second pipelines (11, 12) are connected to each other via a branch pipeline (13). The thermoacoustic heating device (10) is configured such that a branch pipeline (13a) on the prime mover (22) side and the pipeline (12) on the heating device (23) side are positioned adjacent to each other, and a low-temperature side heat exchanger (28) of the heating device (23) is integrally formed with or held in contact with the branch pipeline (13a) on the prime mover (22) side.
