Abstract

In this work, the standard modified thermo-acoustic refrigerator (TAR) is created. It has a stack, heat exchanger, thermocouple, resonator tube, and an acoustic driver (loudspeaker). The effects of a few design factors were investigated for a thermo-acoustic refrigerator system, including wave patterns, frequency, and heat exchanger. It was discovered that a sine wave pattern produced better cooling results than the other wave patterns examined. The heat exchanger's addition greatly increases the temperature reduction that the improved TAR achieves. The acoustic power, temperature drop, and velocity at the fluid's helium entrance velocity (1007, 2000, and 3000 m/s) are all calculated using CFD in this article. To determine the heat flux and temperature distribution for various materials, use thermal analysis (glass for tube, copper for heat exchangers, and stack for Mylar sheet) various models (tube with spiral type stack, spiral type stack with blower type tube, and square tube with square type stack).
