Title (EN) THERMO-ACOUSTIC SYSTEM
(FR) SYSTÈME THERMO-ACOUSTIQUE
Abstract:
(EN) The invention relates to a thermo-acoustic system (1) comprising a chamber (3) enclosing a fluid (9) and in which a sound wave source (2), a wave phase shifter (5) and a thermo-acoustic device (4) are arranged, said thermo-acoustic device (4) being comprised between said source (2) and said phase shifter (5), characterized in that said sound wave source (2) comprises a rigid plate (16) that is bidirectionally translated by a driver device (17) and generates said sound waves that propagate through said fluid (9) and pass through said thermo-acoustic device (4).
(FR) L'invention porte sur un système (1) thermo-acoustique comprenant une enceinte (3) enfermant un fluide (9) et dans laquelle sont disposés une source (2) d'ondes sonores, un déphaseur (5) d'ondes et un dispositif thermo-acoustique (4), ledit dispositif thermo-acoustique (4) étant compris entre ladite source (2) et ledit déphaseur (5), caractérisé en ce que ladite source (2) d'ondes sonores comprend une plaque (16) rigide entraînée en translations bidirectionnelles par un dispositif d'entraînement (17) et générant lesdites ondes sonores se propageant dans ledit fluide (9) et traversant ledit dispositif thermo-acoustique (4).
