摘要
磁制冷技术是以磁性物质为工质,通过等温磁化和绝热去磁达到制冷目的的一种极具开发潜力的高新制冷技术.相比于传统的气体压缩制冷,磁制冷以其高效、节能、环保的特点得到研究者越来越多的青睐.近年来研究发现,与合金、纳米磁制冷材料相比,分子基磁制冷材料在超低温制冷领域表现出较大的优势.本文针对分子基低温磁制冷材料的研究报道及本实验室的相关工作进行总结和讨论,并探究了其发展趋势.
Magnetic refrigeration technology is based on magnetic substances as working medium and achieve refrigeration by isothermal magnetization and adiabatic demagnetization. It displays a great potential for development of high-tech refrigeration technology. Compared to traditional gas-compression refrigeration, magnetic refrigeration is favored by more and more researchers due to its energy-efficient and environmentally friendly superiority. Recent studies indicate that molecular-based magnetic refrigerant materials exhibit great advantage in this field, compared with the alloy and nano magnetic refrigeration materials. In this review, the reported molecule-based magnetic refrigeration materials and our own work are summarized and discussed, and the development trends were evaluated.
