为了提高环管式热声制冷系统的制冷效果，提出了一种相位调节器。PA是用于加速粒子速度的装置。PA嵌入在环管中，并使环管部分的横截面积变窄。PA创建了一个强边界条件，其中粒子速度被加速。据证实，调整声压和粒子速度的相位，使得在环管中产生的声音与总管长以一个波长共振共振。这导致热声冷却系统的冷却效果的极大改善。
A phase adjuster (PA) is proposed to improve the cooling effect of a loop-tube-type thermoacoustic cooling system. A PA is a device for accelerating the particle velocity. The PA is embedded in the loop tube and narrows the cross-sectional area of the part of the loop tube. The PA creates a strong boundary condition in which the particle velocity is accelerated. It is confirmed that the phases of the sound pressure and particle velocity are adjusted so that the sound generated in the loop tube is resonated with the total tube length at one-wavelength resonance. This results in a great improvement in the cooling effect of the thermoacoustic cooling system.
