DESIGN AND RESEARCH OF THE ROOM TEMPERATURE MAGNETIC WINE CABINET

摘要

Anovel permanent magnet composite magnetic refrigerator on room temperature which used the double sets of two concentric quadropole Halbach array magnet was designed. The refrigerant usedGd and GdEr alloy particles and was divided into four parts according to the curie temperature then filled into the regenerator with the quality of 1.5kg. The magnetic refrigerator was applied on the wine cabinetwith the cold room capacity of 92l and the max cooling power was 147W. The cooling capacity of the wine cabinet was measured. The results showed that the max temperature span could exceed 25K and the lowest temperature at the cold end was lower than 267K. The experiment results showed that the wine cabinet had met the requirement of cold storage and could be practical used preliminary.
