GENERATEUR DE CHAMP MAGNETIQUE POUR APPAREIL THERMIQUE MAGNETOCALORIQUE ET PROCEDE DE MONTAGE D'UN TEL GENERATEUR

摘要

The generator (1) has a magnetizing structure (2) creating constant magnetic field in an air gap (3) in which a magnetocaloric element is arranged. The structure has magnetic poles (5, 6) arranged opposite to each other on both sides of a plane of symmetry. Each pole is formed by an assembly of permanent magnets (7, 8) and a ferromagnetic element (9). The ferromagnetic element has a face (F1) projecting with respect to an assembly forming the magnetic poles. The ferromagnetic elements are placed face to face with a spacing forming the air gap of the structure. An independent claim is also included for a method for mounting a magnetic field generator for a magnetocaloric thermal apparatus.
