A travelling wave thermoacoustic piezoelectric refrigerator is provided. The travelling wave thermoacoustic piezoelectric refrigerator includes a housing with two ends connected by an inertance component, a porous stack, a resonator, and a piezoelectric bimorph. The housing comprises a compressible fluid and includes a first portion and a second portion. The porous stack is positioned between the first portion and the second portion. A hot heat exchanger is configured within the second portion near an end of the porous stack opposite to an end of the porous stack near to a cold exchanger configured within first portion. Further, the piezoelectric bimorph is positioned at an end of the resonator opposite to an end of the resonator connected to the second portion. The piezoelectric bimorph oscillates to resonate with the resonator to generate acoustic energy. The acoustic energy triggers travelling acoustic waves within the housing. The travelling acoustic waves traverse between the first portion and the second portion through the porous stack and the inertance component to enable the compressible fluid to transfer heat from the cold heat exchanger to the hot heat exchanger.
