SWINGING MAGNETIC REFRIGERATOR UNDER ROOM TEMPERATURE

摘要

A swinging magnetic refrigerator under room temperature comprises a magnetic field source system of permanent magnets, a magnetic working medium turntable system, a fluid heat exchanging system and a movement control system. The movement control system controls the operation of a turntable box of the magnetic working medium turntable system, and the magnetic working medium (1-8) is brought to come into and out of the magnetic field space. The magnetic working medium (1-8) positioned in the magnetic field space is magnetized and generates heat. The heat generated by the magnetic working medium is transferred to a hot end heat exchanger by a heat transfer fluid flowing to the hot end heat exchanger, and the hot end heat exchanger further transfers the heat to a high temperature space. The magnetic working medium (1-8) out of the magnetic field space is demagnetized and absorbs heat. The heat transfer fluid flows to a cold end heat exchanger. The magnetic working medium (1-8) absorbs heat from a closed low temperature space by the fluid and the cold end heat exchanger, thereby the refrigeration effect under room temperature and the simplification of the structure of the magnetic refrigerator are obtained.
