The present study investigates a thermoacoustic Stirling cycle cooler that uses pressure fluctuation caused by thermoacoustic self-excited vibration for compression. Unlike a mechanical compressor, the thermoacoustic compressor which uses pressure fluctuation does not have a crank mechanism or a piston cylinder, and therefore requires no sealing. This is expected to remarkably improve the reliability and service life of coolers. In this system, the stack plays an important role in the thermoacoustic phenomenon. In this paper, the influence of the stack material and the position on the thermoacoustic phenomenon was reported.
