| 摘要 |
The present invention relates to a heat generator (10) comprising magnetocaloric elements (2) arranged on a circle around a central axis, a magnetic arrangement (3) made of alternating magnetized zones (4) and non magnetized zones (5), located inside the circle formed by the magnetocaloric elements (2), rotated around the central axis and co-operating with a field closing device (6) arranged to loop the magnetic flux generated by the magnetic arrangement to subject alternately the magnetocaloric elements (2) to a magnetic field variation and create alternately in each magnetocaloric element (2) a heating cycle and a cooling cycle, in synchronization with the circulation of at least one heat transfer fluid arranged to pass through the magnetocaloric elements (2) during the heating and cooling cycles, heat generator (1) characterized in that the field closing device (6) comprises a heat insulation means (9). |
