Abstract:

In thermoacoustic refrigeration system sound energy is utilized to obtain cooling effect. Acoustic energy transmits in longitudinal manner through the medium, therefore subsequent compressions and rarefactions in the medium causes warming and cooling the medium. Stack executes as medium to transfer heat from one point in the system to another. Thus stack is the heart of any thermoacoustic refrigeration system. This paper provides a brief overview of the construction and functioning of thermoacoustic refrigeration system and focuses on stack of a thermoacoustic refrigeration system. The stack material desired thermal properties like the thermal conductivity and specific heat have been discussed. An optimum spacing obtained based on the thermal and viscous penetration depths have been briefly discussed. Various stack geometries like parallel plate type, spiral type, pin type and porous stack materials are also discussed.
