• The use of a phase adjuster (PA) is proposed to reduce the temperature difference between the upper and lower ends of the prime mover stack in a loop-tube-type thermoacoustic cooling system. PA is a device for increasing particle velocity. By placing PA in the loop tube, the resonance is forcibly one wavelength. It is confirmed that the temperature difference of the prime mover stack with PA is smaller than that without PA. Because PA prevents the resonance wavelength shift from one-wavelength resonance to two-wavelength resonance, the loop tube suppresses the increase in temperature at the prime mover stack, so that the viscous boundary layer thickness is smaller than the stack channel radius. This induces an effective energy conversion. Consequently, the temperature difference is reduced.
