A standing wave thermoacoustic piezoelectric refrigerator is provided. The standing wave thermoacoustic piezoelectric refrigerator includes a housing, a porous stack, and a piezoelectric bimorph. The housing comprises a compressible fluid and has a first portion and a second portion. The porous stack is positioned between a hot heat exchanger and a cold heat exchanger within the housing, at an end of the first portion of the housing opposite to an end of the first portion having the porous stack and is capable of oscillating to generate acoustic energy upon receiving energy from an external energy source. The oscillation of the piezoelectric bimorph compresses and expands the compressible fluid within the housing. Whereby, the compressible fluid traverses between the first portion and the second portion through the porous stack to generate standing acoustic waves enabling the compressible fluid to transfer heat from the cold heat exchanger to the hot heat exchanger.
