Abstract
A modular thermal apparatus for performing transformation between thermal and acoustic energy is disclosed and includes a housing, first and second fluid ducts extending therethrough, and a regenerator having axially extending regenerator fluid passages. A first heat exchanger conducts thermal energy in the axial direction and includes transversely oriented fluid passages extending through a thermally conductive body and changing direction within the body to terminate axially aligned with the regenerator fluid passages. The apparatus also includes a second heat exchanger having fluid passages extending through a thermally conductive body and terminating in fluid communication with the regenerator fluid passages. Thermal energy is transferred between the heat exchangers and an external thermal energy source or sink. The housing withstands a pressure associated with a pressurized working gas and the fluid ducts provide for connection of the apparatus as a module within an acoustic power loop.
