Patent ID: 8418476

Claim:
A magnetocaloric generator ( 1 ) comprising: at least one thermal stage ( 10 ) being fitted with active elements ( 2 ) made of a magnetocaloric material and arranged around a central axis (A), a magnetic arrangement ( 3 ) supported by a drive shaft ( 30 ) being rotatable around the central axis (A) by an actuator and arranged to subject the active elements ( 2 ) to a variation in magnetic field, at least one heat transfer fluid contained in the generator ( 1 ) and being forced through the active elements ( 2 ) by pushing means ( 7 , 180 ), at least one cold exchange chamber ( 6 ) and one hot exchange chamber ( 5 ) respectively coupled to external utilization circuits, a means for forcing circulation ( 8 a , 8 b , 8 c , 180 ) of the heat transfer fluid, wherein the means for forcing circulation ( 8 a , 8 b , 8 c , 180 ) are integrated in an inner volume of the generator ( 1 ), are coupled to the drive shaft ( 30 ) to be driven by the actuator rotating the magnetic arrangement ( 3 ), and comprising fluid passages ( 82 , 87 , 88 , 187 , 188 ) located inside the generator to facilitate circulation and simultaneous mixing of the heat transfer fluid inside the generator.
