<p>The invention relates to a one-piece part containing a magnetocaloric material not including an alloy including iron and silicon and a lanthanide, characterized in that: said part comprises a base located in a first plane defined by a first direction (Dx) and a second direction (Dy), and a set of N unit blades (La,i) rigidly connected to said base; said blades have a first dimension (D Lj,x) in the first direction, a second dimension (D L ai,y) in the second direction and a third dimension (D L ai, ) in a third direction (Dz) perpendicular to the first and second directions; an if blade is separated from an (i+l) f blade by an if distance (d i); the ratio between the second dimension and the first dimension is greater than or equal to 10; the ratio between the third dimension and the first dimension is greater than or equal to 6; and the first dimension is of the same order of magnitude as said distance between an if blade and an (i+l) f blade. The invention also relates to a heat generator comprising the one-piece parts of the invention.</p> |
