Abstract
(EN)
A thermoacoustic device using a loop tube and capable of rapidly and efficiently performing heat exchange by rapidly generating a standing wave and a traveling wave and a thermoacoustic system. The thermoacoustic device comprises, in the loop tube (2), a first stack (3a) held by a first high temperature side heat exchanger (4) and a first low temperature side heat exchanger (5) and a second stack (3b) held by a second high temperature side heat exchanger (6) and a second low temperature side heat exchanger (7). Sound wave by self-excitation is generated by heating the first high temperature side heat exchanger (4), and the second low temperature side heat exchanger (7) is cooled by the standing wave and the traveling wave. The loop tube comprises a plurality of straight tube parts (2a) along the vertical direction and connection tube parts (2b) formed shorter than the straight tube parts (2a), and the first stack (3a) is installed in the longest straight tube part (2a).

Il est prévu un dispositif thermoacoustique à l’aide d’un tube en boucle et capable de réaliser rapidement et efficacement un échange thermique en générant rapidement une onde stationnaire et une onde progressive et un système thermoacoustique. Le dispositif thermoacoustique comprend, dans le tube en boucle (2), une première pile (3a) contenue par un premier échangeur thermique côté haute température (4) et un premier échangeur thermique côté basse température (5), et une seconde pile (3b) contenue par un échangeur thermique côté haute température (6) et un second échangeur thermique côté basse température (7). Une onde sonore par auto-excitation est générée par chauffage du premier échangeur thermique côté haute température (4), et le second échangeur thermique côté basse température (7) est refroidi par l’onde stationnaire et l’onde progressive. Le tube en boucle comprend une pluralité de parties tubulaires rectilignes (2a) dans la direction verticale et des parties tubulaires de connexion (2b) plus courtes que les parties tubulaires rectilignes (2a), et la première pile (3a) est installée dans la partie tubulaire rectiligne la plus longue (2a).
