Abstract :
The optimal frequency characteristics of a standing-wave thermo-acoustic cooler filled with parallel plates are investigated in this paper. The expression for the optimal frequency of the cooler at the maximum cooling load is derived. Numerical examples are given to show the effects of the plate spacing and the portrait temperature gradient along the plates on the optimal frequency. The results obtained herein can provide some theoretical guidance for the design of practical thermo-acoustic coolers.
