Abstract:
1. A power transmission unit for thermo-acoustic systems including at least one stage, said thermo-acoustic systems each including an acoustic resonator including a tube and containing a fluid and wherein an acoustic field is established exhibiting adimensional high impedance zones and adimensional low impedance zones, said at least one stage comprising: a couple of two adjacent tube elements ( a section of at least one tube of reduced diameter ( in the one stage, the narrow section linking two respective adjacent ends of the two adjacent tube elements ( in the thermo-acoustic system, two successive thermo-acoustic units being always separated by a narrow section, wherein, each of the two respective adjacent ends of the two tube elements of the couple includes one of i) one derivation ( each derivation comprises a conduit ( each said derivation ( each derivation is mounted on the end of the corresponding adimensional high impedance zone contiguous to the corresponding narrow section.
