Experimental investigation was carried out to miniaturize thermoacoustic cooling system. In the thermoacoustic cooling system, relationship between frequency and total length is inverse proportional. Therefore the frequency becomes high when the system is miniaturized. From this reason, the study of heat pump stack matched to frequency is needed. In this research, we focused on two parameters. One is the channel radius and the other is installation position of stack. These parameters relate to cooling efficiency. Then we measured cooling property relevant to these parameters. From experimental results, it was confirmed that the cooling property of stack position indicated similar tendency in every length. And the optimal installation position of stack was different by channel radius. From this, it is expected that cor and phase differenceφ can be applied as a design method of heat pump.
