The invention concerns a magnetic field generator (G1 l), for a magnetocaloric thermal device, comprising first (SM11) and second (SM21) identical magnetising structures, mounted head-to-tail, on either side of a central plane (P), and defining two air gaps (E1, E2). Each magnetising structure (SM 11, SM21) comprises first (AM1) and second (AM2) magnetising assemblies, of which the induction vectors are oriented in opposite directions, and mounted on a support(SUPI)Each magnetising assembly (AM1, AM2) has a permanent magnet structure (AP1, APC) comprising a passive face (FP1, FP2), and an active face (FA1, FA2) delimiting said air gaps (E1, E2). This generator is characterised by the fact that the induction vectors of the first (AM 1, AM19) and second (AM2, AM29) magnetising assemblies form, within said generator, a single circulation loop of a magnetic field through said supports (SUPI)and said air gaps (E1, E2, E3, E4). |
