摘要
磁致冷是利用磁介质在其居里温度Tc附近具有较大磁热效应的特性实现的一种物理现象。以稀土金属Gd为磁致冷材料,对室温旋转式磁致冷演示样机进行了结构设计,演示样机可达4.4K的制冷温跨,用于设计性实验教学,具有良好的示范作用。
The magnet refrigeration is a physical phenomenon based on the characteristics of the magnet medium with a great magnet-heat effect at the temperature near the curie Tc. The structure design for a prototype of the revolving magnet refrigeration with the rare metal Gd as the magnet medium running under the ambient temperature is conducted. The temperature span of the prototype reaches to 4.4K. The design can be a demonstration in practical teaching for structure design.
