High-power thermoacoustic refrigerator

A high-power thermoacoustic refrigerator comprising:

• a half-wave length resonator;
• at least two housings having loudspeakers disposed therein fixedly mounted at first and second ends of said resonator;
• a plurality of heat exchangers disposed in said resonator in close proximity to said loudspeakers;
• at least two stacks disposed within said heat exchangers;
• a compressible fluid disposed within said resonator, wherein said fluid is an adjustable binary mixture of inert gases capable of being tuned to the half-wave length resonance of said resonator and said loudspeakers;
• at least two high acoustical impedance ends of said resonator of non-uniform cross-section deposed in said resonator for containing said compressible fluid proximate to said stacks and said heat exchangers;
• a plurality of transfer fluids disposed in said heat exchangers for transferring heat;
• a plurality of voice coils wired 180 degrees out of phase disposed in said loudspeakers for oscillating said compressible fluid;
• a plurality of pusher cones proximate to said voice coils for compressing and decompressing said compressible fluid during the oscillating of a standing half-wave length in the resonator to efficiently transfer heat from the heat exchangers during operation;
• a plurality of bellows disposed between said pusher cones and said housing and forming a flexible seal between said housing and said resonator;
• and
• a plurality of mounting springs disposed within said housings for mounting said pusher cones wherein
• said pusher cones are disposed between said bellows and said springs for maintaining proper alignment of said pusher cones within said housings.

A high-power thermoacoustic refrigerator comprising:

• a half-wave length resonator;
• at least one housing fixedly mounted to first and second ends of said resonator, said housing having a at least one loudspeaker with a double-acting piston disposed therein;
• a plurality of heat exchangers disposed in said resonator, proximate to said loudspeaker;
• at least two stacks disposed within said heat exchangers;
• a compressible fluid disposed within said resonator, said fluid being tuned to the half-wave length resonance of said resonator;
• at least two high acoustical impedance ends of said resonator of non-uniform cross-section fixedly mounted proximate to said double-acting pistons for containing said compressible fluid;
• a plurality of transport fluids disposed in said heat exchangers for transferring heat;
• a plurality of voice coils wired with a 180 degrees phase difference disposed in said loudspeaker;
• and
• a plurality of pusher cones disposed in said loudspeaker, said cones having a bellows and springs proximate to said voice coils for compressing said compressible fluid to an oscillating standing half-wave length in the resonator, whereby the oscillating fluid efficiently pumps heat during operation.
