Description

technical field [0001] The invention relates to a magnetic refrigeration technology, in particular to a thermal cycle system of a rotary room temperature magnetic refrigerator. Background technique [0002] At present, according to the operation mode of the magnetic field, magnetic refrigerators can be divided into reciprocating type and rotary type. Among them, the reciprocating operation frequency is low, and the refrigeration efficiency is difficult to improve; the rotary magnetic refrigerator generally refers to a refrigerator that rotates with a magnetic field or a refrigeration bed, with high rotation speed and relatively strong refrigeration capacity, so it is the most promising industrialization and application in real life. magnetic refrigerator. [0003] The magnetic field system of the rotary magnetic refrigerator is mostly composed of two magnets mounted on both sides and a central magnetically conductive material, and the magnetic working fluid bed is a multi-s...

AI Technical Summary

Problems solved by technology

Since the magnetic field is static and the magnetic working medium bed rotates, the heat exchange system is very complicated, the manufacturing cost is high, subsequent disassembly and assembly are difficult, and maintenance is not easy
