摘要： The present invention provides a single-stage double-acting traveling-wave thermoacoustic system, comprising three elementary units, wherein each unit comprises a linear motor and a thermoacoustic conversion device. The linear motor comprises a cylinder and a piston, wherein the piston can perform a straight reciprocating motion in the cylinder. The thermoacoustic conversion device comprises a first heat exchanger, a heat regenerator, a second heat exchanger, a thermal buffer tube and a third heat exchanger connected in sequence, wherein the first heat exchanger and the third heat exchanger of each thermoacoustic conversion device are connected to cylinder cavities of different linear motors respectively, forming a loop structure for flow of a gas medium. The single-stage double-acting traveling-wave thermoacoustic system provided in the present invention comprises a thermal buffer tube and a third heat exchanger, which makes the temperature of the gas medium fed back to the cylinder cavity of another linear motor be close to the room temperature, so as to ensure the piston and the cylinder working at room temperature, thus reducing the manufacturing cost of the single-stage double-acting traveling-wave thermoacoustic system, and extending its service life.
