Analysis of 3D Printed Stack in Thermoacoustic Cooling

Inconsistencies in fabricated thermoacoustic stacks are due to the methods available obtain desired geometry and dimensions even under optimized design parameters. This paper presents performance results from using 3D printing technology which minimizes error, disposes of irregularities can reduce production time. In this study, a refrigerator was determined measurements temperature difference across various printed stack lengths fabricated. Experiments were done at 400 Hz frequency with different plate spacing thickness, 21-mm diameter resonator. Results show that 0.7 mm 0.5 thickness performed better compared those smaller same or but larger thickness. The outcomes study have shown need for fabrication keep pace realize global efforts towards sustainable environment.
