We discuss the cooling effect of a loop-tube-type thermoacoustic cooling system especially emphasizing the effect of the heat pump placed in the resonance tube. The temperature decrease for the loop tube connected by the resonance tube with the heat pump placed in the resonance tube is 25 ℃, while the temperature decrease for the loop tube without the resonance tube with the heat pump placed in the loop tube is only 9 ℃. This is the effect of the heat pump placed in the resonance tube. The heat pump placed outside of the loop tube suppresses an influence of not only the viscosity effect of the heat-pump stack but also the undesirable heat flow caused by the acoustic streaming. According to this, the connection of the resonance tube contributes to an improvement. Consequently, the heat pump placed in the resonance tube connected to the loop tube improves the cooling effect of the loop tube.
