Abstract(in English) | Experimental investigation was carried out to miniature thermoacoustic cooling system. The loop tube cooling system is one of the thermoacoustic cooling system. In the loop tube, relationship between frequency and total length is inverse proportional. Therefore the frequency becomes high when the system is miniaturized. From this reason, the optimal condition to cool efficiently changes at the heat pump. In this research, we focused on two parameters. One is the ωτ 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, when the system was miniaturized up to approximately 100mm, minimal temperature decrease was confirmed by adjusting ωτ and installation position. And the optimal installation position of stack was different by ωτ. From this, it is expected that ωτ and sound field can be applied as a design manual of heat pump. |
