This paper deals with design and fabrication of thermo acoustic refrigeration, a theory of using sound waves as a coolant. A thermo acoustic refrigeration device (TAR), which includes an acoustic wave generation device arranged to the channel of a hollow tube, and a regenerator is provided at a predetermined position in the channel of the tube. The main aim is to design and fabricate a small thermo acoustic refrigerator from inexpensive and readily available parts and analyses the result. This design includes dimension of stack, selection of acoustic driver, and acoustic resonator. This Experiment shows that, thermo acoustic cooling is possible, but high efficiency is beyond to reach due to materials restrictions. The temperature gradient of 50 C is obtained by constructing this simple device. Experiment shows the performance can be improved by using a better material which having a high heat carrying capacity and the working fluids like inert gases.
