Abstract

A thermoacoustic cooling device includes a tube in which a working fluid is enclosed; a first stack that generates acoustic waves in the working fluid with use of a temperature gradient; a first high-temperature heat exchanger provided at a first side of the first stack to heat the first side of the first stack; a first low-temperature heat exchanger provided at a second side of the first stack; a second stack in which a temperature gradient is generated by the acoustic waves; a second high-temperature heat exchanger provided at a first side of the second stack, which has a high temperature; a second low-temperature heat exchanger provided at a second side of the second stack, which has a low temperature; and a heat transfer portion configured to connect the second low-temperature heat exchanger to the first low-temperature heat exchanger so as to transfer heat therebetween.
