Novel thermoacoustic refrigerator driven by electromagnetic compressor

The utility model relates to a novel thermoacoustic refrigerator driven by an electromagnetic compressor. The thermoacoustic refrigerator comprises the electromagnetic compressor consisting of a high-magnetism piston, a first electromagnetic coil and a second electromagnetic coil, and a thermoacoustic refrigerator consisting of a hot-end heat exchanger, a plate stack, a cold-end heat exchanger, a resonant tube and a resonant cavity. The electromagnetic compressor and the thermoacoustic refrigerator are connected with each other. The first electromagnetic coil and the second electromagnetic coil evenly surround the straight track pipe at the head position and the tail position, the high-magnetism piston is arranged in the straight track pipe and sealed through the sealing ring, and the high-magnetism piston moves back and forth in the straight track pipe under the acting force of a magnetic field to compress gas, generate pressure waves and drive the thermo-acoustic refrigerator to generate cooling capacity.
