ループ管型熱音響デバイスにおける積層樹脂で製作されたスタック管壁の熱的影響

This study is a basic research to validate the application of a laminated resin to an outer cylinder of a stack in a thermoacoustic device. A loop-tube type thermoacoustic device was selected. The looped tube having the length of 3 m and the inner diameter of 40 mm was used. The device consists of two engine parts in which heat is converted to sound and one cooler part in which sound is converted to heat and thereby cooling effect can be generated. A honeycomb ceramic was used as the stack in the device. It was confirmed that the heat loss in the laminated resin is reduced as compared with conventional stainless steel outer cylinders. In addition, the heat resisting property usable as an outer cylinder of a stack was shown.
