摘要
磁制冷的发展除了取决于磁工质的发展外,提供性能优良的外磁场磁路同样具有举足轻重的作用。本文在中空圆柱型磁场源(hollow cylindrical flux source)的基础上,设计出适用于旋转式室温磁制冷机的永磁磁路。在保证工作气隙一定磁感应强度的情况下,通过Ansys软件进行优化,设计出了一种工作气隙中心平均磁感应强度≥1.75T的高场强永磁磁路。相对于未优化的磁路,工作气隙中心平均磁感应强度提高了20%,磁体质量降低了21%。
Besides improvement of the magnetic refrigerant materials for development of magnetic refrigeration, an excellent magnetic field source is same important. Based on the hollow cylindrical flux source, a permanent magnetic circuit is designed for rotating room-temperature refrigerator. And after optimization by Ansys software, a permanent magnetic circuit, in which the average magnetic induction strength at the center of the working gap is up to 1.75 T, is got. Relative to the unoptimization magnetic circuit by Ansys software, the average magnetic induction strength in the center gap raise by 20%, and the magnetic circuit weight descend by 21%.
