THERMOACOUSTIC DEVICE

摘要

A thermocoustic device (110) includes a housing (120) with a thermal core supported in the housing and having a first and a second surface. The therma l core includes a first heat exchanger (112) defining the first surface of the thermal core and a second heat exchanger (116) defining the second surface o f the thermal core. A main chamber is in fluid communication with the first surface of the thermal core and a secondary multiplier chamber is in fluid communication with the second surface of the thermal core. A working volume (144) of a gaseous working fluid fills the main chamber, the multiplier chamber, and the thermal core at a pressure. An equilibrium pressure is defined as the pressure of the working volume of gaseous working fluids with the thermoacoustic device is in a non-operating mode.
