| Abstract: | 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. |
