Résumé

A thermoacoustic cooler prototype was investigated experimentally. Using modelling tools based on linear thermoacoustic theory, the system was designed to provide 140 W of cooling across a 22 °C temperature lift. Operation using a 55% helium-argon mixture at a mean pressure of 20 bars and a frequency near 180 Hz was targeted. The prototype used a moving magnet electro-mechanical actuator. An analysis of the different results is presented as well as the reasons why the targeted results were not obtained. Several measurements were performed to determine the cause of the discrepancies in pressures, temperatures, and cooling power between measured and predicted values. The possible influences of steady streaming flows, nuisance heat loads, gas mixture inhomogeneity and stack and heat exchanger performance were investigated.
