The pulse thermoacoustic refrigerating device comprises a sound wave generating pipe and a pulse refrigerating pipe, moving parts are arranged at the two ends of the sound wave generating pipe, a pulse hole is formed in the middle of the sound wave generating pipe, one end of the pulse refrigerating pipe communicates with the pulse hole to receive sound waves, and the other end of the pulse refrigerating pipe communicates with the sound wave generating pipe. One end of the pulse refrigeration pipe is a sound wave, the other end of the pulse refrigeration pipe is a closed end so that the sound wave can be rebounded and reversely propagated to form a high-pressure area and a low-pressure area, the pulse refrigeration pipe is further provided with a heat exchange part located at the joint of the high-pressure area and the low-pressure area, and the cold side of the heat exchange part is located in the low-pressure area and leads out the low temperature of the low-pressure area. According to the invention, the hu
