Abstract
A radial acoustic driver uses to generate higher amplitude of pressure fluctuation with radial type standing wave. The radial acoustic driver includes a cyclic type resonance tube which is filled with a working fluid inside, and a ring type electricity-acoustic energy transducer that is inside the cyclic type resonance tube for generating a radial acoustic wave when receiving electricity.
Claims10
A radial acoustic driver comprising:
- a cyclic type resonance tube which is filled with a working fluid inside;
- and
- a ring type electricity-acoustic energy transducer, inside the cyclic type resonance tube for generating a radial wave to the working fluid when receives electricity.
A thermoacoustic device using a radial acoustic driver comprising:
- a cyclic type resonance tube which is filled a working fluid inside;
- a ring type electricity-acoustic energy transducer for generating a radial standing wave along the cyclic type resonance tube when receives electricity;
- a plurality of cyclic stacks, distributed in the space of the ring type resonance tube and made of a plurality of plates which have at least one supporting element to support the structure of the stack, forming a passage for passing through the working fluid;
- and
- a plurality of heat exchangers, mounted at both sides of the stack for heat exchange with outside.
