Magnetic field generator for magnetocaloric thermal apparatus utilized in e.g. heating field, has magnetizing structure creating constant magnetic field in air gap, and ferromagnetic elements placed face to face with spacing forming air gap

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.
