A heat generator comprising a magneto-caloric material and a method for generating efficient and reliable thermies enabling of substantially limiting displaceable inert masses in order to produce a magnetic field variation required for obtaining a magneto caloric effect and usable by individuals and/or industries. The generator (10) comprises magneto caloric thermal elements (Ti) which are circularly arranged and crossed by conduits containing coolant flowing therethrough and magnetic elements (Gi) exposing the thermal elements (Ti) to a magnetic field action. The generator (10) also comprises magnetic divergence (mj) elements arranged between the thermal elements (Ti) and the magnetic elements (Gi) and coupled to displacement mechanism (not represented) for moving from one thermal element (Ti) to another thermal element (Ti+1) and initiating the magnetic flux variation in the thermal elements (Ti), thereby promoting the calorie and/or frigorie generation. The generator (10) can be used for tempering, cooling, heating, conserving, drying and air-conditioning.
A heat generator (10-14) with magneto-caloric material comprising at least one thermal element (Ti), at least one magnetic element (Gi) for generating a magnetic field, said at least one thermal element (Ti) being located opposite said at least one magnetic element (Gi) so said at least one thermal element (Ti) being subjected to at least one portion of said magnetic field, said heat generator (10-14) also comprising magnetic modulation means (Mj, mj) for varying the magnetic field received by said at least one thermal element (Ti) and a means for recovering at least a portion of thermies generated by said at least one thermal element (Ti) subject to the variable magnetic field, said magnetic modulation means comprises at least one magnetic modulation element (Mj, mj) that is magnetically conductive, coupled with a displacement means for alternately displacing the magnetic modulation element relative to said at least one magnetic element (Gi) and to said at least one thermal element (Ti) between an active position, in which the magnetic modulation element is close to said at least one magnetic element (Gi) and said at least one thermal element (Ti) and channels at least the portion of said magnetic field that being received by said at least one thermal element (Ti), and an inactive position, in which the magnetic modulation element is distanced from at least one of said magnetic element (Gi) and said at least one thermal element (Ti) and has no effect on the portion of the magnetic field.
