| 简介 |
A one-piece part based on magnetocaloric material comprising an alloy comprising iron and silicon and a lanthanide, comprises a base in a first plane defined by a first and second direction and N unitary blades secured to the base; the blades having a first and second dimension in the first and second direction, respectively, and a third dimension in a third direction at right angles to the first and second dimensions; an ith blade being separated from an (i+1)th blade by an ith distance; the ratio between the second dimension and first dimension being at least 10; the ratio between the third dimension and first dimension being at least 6; the first dimension being the same order of magnitude as the distance separating an ith blade from an (i+1)th blade. The magnetocaloric material can be rare-earth alloy or a composite material based on polymer binder and rare-earth alloy. |
