Phase Adjuster (PA) is proposed for improvement in the cooling effect of the thermoacoustic cooling system. PA is a device for adjusting the phases of the sound pressure and the particle velocity, by creating a strong boundary condition that the particle velocity is accelerated. It is confirmed that PA adjusts the phases of the sound pressure and the particle velocity so that the sound generated in the system is resonated by 1 wavelength at lower frequency. This results in great improvement in cooling effect of the thermoacoustic cooling system. It is regarded that PA suppresses a generation of the acoustic streaming. Since the acoustic streaming decreases the cooling effect, also in this point, it can be said that PA improves the cooling effect of the thermoacoustic cooling system.
