MULTI-STAGE THERMOACOUSTIC GENERATOR UNIT AND MULTI-STAGE HEAT REGENERATIVE REFRIGERATION SYSTEM HAVING SAME

WIPO Patent Application WO/2018/028367

A1

A multi-stage thermoacoustic generator unit and a multi-stage heat regenerative refrigeration system having same. The multi-stage thermoacoustic generator unit comprises multiple sets of thermoacoustic engines which are sequentially connected between a compressor and a generator and are coupled with one another by means of resonator assemblies for enabling traveling-wave sound fields to be generated in each set of thermoacoustic engines simultaneously. By means of the resonator assemblies, the adjacent two sets of thermoacoustic engines match well with each other, and traveling-wave sound fields can be generated in each set of thermoacoustic engines simultaneously, such that the thermoelectricity efficiency of the thermoacoustic generator unit is improved. Moreover, by setting different operating temperatures for each set of thermoacoustic engines, the multi-stage thermoacoustic generator unit can use thermal energy of different grades in a stepped manner, such that the multi-stage heat regenerative refrigeration system having the unit has increased thermoelectric conversion efficiency.
