Abstract A thermoacoustic cooler, using a resonant standing acoustic wave, has been built. It employs a loudspeaker to sustain a standing wave in a resonance tube. In the helium-filled tube, a layered parallel-plate structure, called stack, and two heat exchangers are installed. The interaction of the compressed and expanded gas in the channels of the stack with the surface generates heat transport. A description of the cooler is presented, together with the first performance measurements using two different stacks, two different average pressures, and different dynamic pressures.
