Abstract
A refrigerator includes a housing, a discharge device, a cold finger device, and at least two compression devices. A disassembly and assembly hole is provided on the housing located between the at least two third accommodating cavities arranged at intervals, and the disassembly and assembly hole is communicated with the first accommodating cavity and is configured for the disassembly and assembly of the discharge device. By arranging the disassembly and assembly hole, the disassembly and assembly steps of the discharge device are simplified, meeting the need of rapid testing of the compression device. By arranging the discharge device with a stepped piston, the service life of the discharge device is increased and the discharge device has higher reliability and consistency. By arranging a tree topology or net topology, the flow resistance of gas may be reduced and the refrigeration efficiency may be improved, achieving multi-stage refrigeration.
