<P>PROBLEM TO BE SOLVED: To provide a thermoacoustic cooling device capable of efficiently carrying out temperature control of a second heat exchanger converting acoustic energy into thermal energy by a simple configuration. Ž<P>SOLUTION: A first heat exchanger 1 includes a first high temperature side heat exchange part 11, a first low temperature side heat exchange part 12, and a first stack 13 disposed between the first high temperature side heat exchange part and the first low temperature side heat exchange part, and self-induced acoustic waves are generated by inputting heat generated from a heat source 4 into the first high temperature side heat exchange part. The second heat exchanger 2 includes a second high temperature side heat exchange part 21 disposed on an end of piping 3, a second low temperature side heat exchange part 22, and a second stack 23 disposed between the second high temperature side heat exchange part and the second low temperature side heat exchange part, and acoustic waves transmitted through the piping is converted into thermal energy to cool the second low temperature side heat exchange part. The second heat exchanger is disposed on an end of the piping, and an end of the second heat exchanger is blocked. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
