摘要
由于室温磁制冷材料在磁制冷机工作中存在许多问题,致使磁制冷机工作频率不高,制冷功率低。针对不同形状、不同种类的磁制冷材料本身导热系数低和金属间化合物的特点,分析比较了几种成型工艺方法,提出了一种新的成型工艺方案。
Room-temperature magnetic refrigerant materials have many defects in use. These disadvantages cause the magnetic refrigerator has low frequency of exchanging heat and the power. Aiming at the low thermal conductivity of magnetic refrigerant materials themselves and the characteristic of the inter-metalllc compound, this paper analyzed and compared with different technical methods, and then raised a new technical scheme.
