Abstract

The invention relates to the technical field of generating sets, in particular to a double-acting thermoacoustic generator utilizing liquid metal for electric conduction. The double-acting thermoacoustic generator comprises at least three sets of thermoacoustic generating units which are connected in series to form a closed loop, wherein each set of thermoacoustic generating unit comprises a thermoacoustic engine, a liquid storage pipe with liquid metal arranged therein and at least one frictional generator; each frictional generator comprises an external load and two electrodes arranged in the corresponding liquid storage pipe, one of the electrodes is always in contact with the liquid metal, and a power generation material layer is arranged on the outer surface of the other electrode; the thermoacoustic engines push the liquid metal to do lifting reciprocating motion, so that the electrodes with the power generation material layers and the liquid metal are switched between a contact state and a separated state. According to the application, the liquid storage pipes with the liquid metal play the role of harmonic oscillators, the conductivity is excellent, the performance is stable, the reliability is high, the structure is simple, the production cost is low and the practicability is high.
