Single-stage double-acting traveling-wave thermoacoustic system

Abstract

The present invention provides a single-stage double-acting traveling-wave thermoacoustic system, comprising three elementary units; each unit comprises a linear motor and a thermoacoustic conversion device. The linear motor comprises a cylinder and a piston; the piston can perform 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, 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 of a gas medium flow. The system comprises a thermal buffer tube and a third heat exchanger, making the temperature of gas medium given feedback to the cylinder cavity of another linear motor be close to the room temperature, ensuring the piston and cylinder working at room temperature.
