Abstract
Provided is a thermoacoustic refrigerator including an air column pipe, a prime mover, a load, and a heat accumulation tank. An exhaust gas supplied to and discharged from the heat accumulation tank is supplied, as a heat source, to the prime mover disposed inside the air column pipe, so as to cause self-oscillation of a working gas filled in the air column pipe so that sound waves are generated. With the sound waves, the load disposed inside the air column pipe converts sound wave energy into heat energy, so as to output cold heat.
Claims7
A thermoacoustic refrigerator comprising:
- an air column pipe filled with a working gas;
- a prime mover disposed inside the air column pipe and configured to generate sound waves;
- a load disposed inside the air column pipe and configured to output cold heat;
- and
- at least one heat accumulation tank having an internal space provided with a heat accumulation body, said at least one heat accumulation tank being connectable to the prime mover,
- the prime mover being connected to said at least one heat accumulation tank,
- said at least one heat accumulation tank receiving a first heating medium supplied thereto, said at least one heat accumulation tank discharging and supplying, to the prime mover, the first heating medium having undergone heat exchange so that self-oscillation of the working gas is caused and sound waves are generated in the prime mover,
- the load being operated by the sound waves thus generated.
