Abstract:
1. A device for generating a thermal flux with magneto-caloric material, the device comprising at least one thermal flux generation unit ( 10 , 30 ) provided with at least two thermal bodies ( 11 , 21 , 31 , 41 a , 41 b ), each containing at least one magneto-caloric element ( 12 , 22 , 32 ), magnetic means ( 103 , 203 , 303 , 403 ) being arranged for emitting at least one magnetic field, displacement means coupled to the magnetic means ( 103 , 203 , 303 , 403 ) for moving the magnetic means ( 103 , 203 , 303 , 403 ) relative to the magneto-caloric elements ( 12 , 22 , 32 ) to subject the magneto-caloric elements ( 12 , 22 , 32 ) to a magnetic field variation to vary a temperature the magneto-caloric elements ( 12 , 22 , 32 ), and a recuperation means for recuperating at least one of calories and frigories that are emitted by the magneto-caloric elements ( 12 , 22 , 32 ), the displacement means reciprocating and being arranged for moving the magnetic means ( 103 , 203 , 303 , 403 ) relative to the magneto-caloric elements ( 12 , 22 , 32 ) in a reciprocating motion; the recuperation means comprises at least two heat transfer fluid circuits ( at least one of the at least two circuits (
