The efficiency of a thermoacoustic device including a gas-filled, elongated resonator tube (10), an acoustic driver (16) and a tube (10) for establishing a standing wave therein, an elongated stack (20) within the tube (10) having opposite (24, 26) spaced from the driver (16) can be increased with f
The efficiency of a thermoacoustic device including a gas-filled, elongated resonator tube (10), an acoustic driver (16) and a tube (10) for establishing a standing wave therein, an elongated stack (20) within the tube (10) having opposite (24, 26) spaced from the driver (16) can be increased with first and second heat exchangers (28, 30) in proximity to the stack (20) at each end (24, 26) thereof where each of the heat exchangers comprises at least one tube (56, 70) formed into a plurality of spaced runs (58, 60, 62, 64, 66, 68, 72, 74, 76, 78, 80, 82). The tubes (56, 70) have an inlet (96) and an outlet (102) spaced therefrom and fins (94) are bonded to the tubes (56, 70) in the spaces between the runs (58, 60, 62, 64, 66, 68, 72, 74, 76, 78, 80, 82).

In a thermoacoustic device, the combination of: gas filled elongated, resonator tube; an acoustic driver in said tube for establishing a standing wave therein; an elongated plate within said tube, said plate having opposite ends spaced from said driver; first and second heat exchangers in proximity
In a thermoacoustic device, the combination of: gas filled elongated, resonator tube; an acoustic driver in said tube for establishing a standing wave therein; an elongated plate within said tube, said plate having opposite ends spaced from said driver; first and second heat exchangers in proximity to said plate, one at each end thereof; at least one of said heat exchangers comprising a tube bent into a plurality of spaced runs; said tube having an inlet and an outlet spaced therefrom; and fins bonded to said tube in the spaces between said runs; said plate being in a plurality of spaced runs, the spacing between said plate runs defining a first-free flow area for said gas; and the spacing between the tube runs with said fins in place defining a second free-flow area substantially equal to said first free-flow area. The thermoacoustic device of claim 1 wherein there are a plurality of said tubes defining a plurality of generally concentric runs, said inlet and said outlet being common to said plurality of tubes.
