Description

Technical field [0001] The present invention relates to a household electrical appliance, in particular to a refrigeration refrigerator, which includes a refrigerator casing. Background technique [0002] Current household refrigerators generally use a compressor system. For this type of traditional refrigerator, the compressor makes a lot of noise during operation, and the compressor system has a high probability of failure, which often leads to maintenance troubles. [0003] In view of the problems existing in traditional compressor refrigerators, magnetic refrigeration refrigerators have been made according to the magnetic refrigeration effect. The principle is that when a paramagnet is magnetized, its internal magnetic order is enhanced, that is, its magnetic entropy decreases. , then the paramagnet will release heat and increase the entropy of the outside world. When the paramagnet is demagnetized, its internal magnetic order will decrease, that is, the magnetic entropy...

AI Technical Summary

Problems solved by technology

In the current magnetic refrigeration refrigerator, the cooling effect is obtained mainly through a ring composed of paramagnets, which rotates continuously inside and outside the refrigerator. For this kind of refrigeration ring structure, a large layout space is required, which increases the capacity of the refrigerator. In addition, because the refrigeration ring needs to rotate, the magnetized body cannot be close to the refrigeration ring, and the air gap between them will cause a large magnetic flux leakage, and the magnetic field strength of this kind of external magnetic field is mainly concentrated on the external magnet itself, so the magnetic field The energy utilization rate is small, and it is necessary to use a superconductor to establish a strong magnetic field to meet the strong magnetization of the refrigeration ring, which makes the manufacturing cost higher
