Monobloc part comprising a magnetocaloric material comprising an alloy comprising iron and silicon and at least one lanthanide, and method of manufacturing said monobloc part

摘要

Monobloc part comprising at least one magnetocaloric material comprising an alloy comprising iron and silicon and at least one lanthanide, and comprising: - said part consists of a base (E) located in a first plane defined by a first direction (Dx ) and by a second direction (Dy) and a set of N unit sheets (La, i) attached to said base (E); - said sheets having a first dimension (DLai, x) according to the first direction (Dx), a second dimension (DLai, y) according to the second direction (Dy) and a third dimension (DLai, z) according with a third direction (Dz) perpendicular to the first and second dimensions; - a ith sheet that is practically parallel to, and separated from, a (i + 1) th sheet a ith distance (di); - the relationship between the second (DLai, y) and the first dimension (DLai, x) being greater than or equal to 10; - the relationship between the third dimension (DLai, z) and the first dimension (DLai, x) being greater than or equal to 6; - the first dimension being of the same order of magnitude as said distance (di) that separates one ith sheet (La, i), from one (i + 1) th sheet (La, i + 1).
