The invention relates to a traveling-wave thermo-acoustic heat engine (refrigerator). A double-drive stirling traveling-wave refrigerator is characterized by including a first vibration exciter (1), a first thermo-acoustic refrigeration element (3), a ring-shaped channel housing (4), a second thermo-acoustic refrigeration element (6) and a second vibration exciter (8), wherein a ring-shaped traveling-wave transmitting passage (5) is arranged inside the ring-shaped channel housing (4), the first vibration exciter (1) is arranged at the first port of the ring-shaped channel housing (4), the second vibration exciter (8) is disposed at the second port of the ring-shaped channel housing (4), the first thermo-acoustic refrigeration element (3) and the second thermo-acoustic refrigeration element (6) are respectively distributed inside the ring-shaped traveling-wave transmitting passage (5), one end close to the first vibration exciter (1) of the first thermo-acoustic refrigeration element (3) is a hot end heat exchanger (9), and one end close to the second vibration exciter of the second thermo-acoustic refrigeration element (6) is a hot end heat exchanger. The double-drive stirling traveling-wave refrigerator has the advantages of simple structure and high efficiency, which can realize double objects cooling and single object cooling.
