We built and tested a thermoacoustic Stirling cooler. This cooler is composed of a looped tube and resonator. The energy conversions through the Stirling cycle are achieved by acoustically oscillating fluid in two regenerators located in the looped tube. In one of the regenerators, axial heat flow is converted into acoustic power flow, and in the other, heat pump effects are induced by the generated acoustic power flow. The lowest temperature of-26℃ was obtained when input power was 850 W. This type of cooler works without any moving parts like pistons. Therefore the cooler is potentially a powerful tool for application to generate refrigeration.
