Patent ID: 8695354

Claim:
A thermal flux generating device with magnetocaloric material ( 10 , 20 , 100 , 50 , 60 ) comprising: at least one thermal flux generating unit housed in an external shell ( 11 , 21 , 91 , 201 ) and equipped with at least one thermal element containing at least one magnetocaloric element; at least one magnetic arrangement arranged so as to generate a magnetic field; at least one electric drive arranged so as to facilitate relative movement of the magnetic arrangement in relation to each of the at least one magnetocaloric element ( 13 , 23 , 56 , 66 , 99 , 207 ) to subject each of the at least one magnetocaloric element to a variation in magnetic field and to cause a temperature of the magnetocaloric element to vary; means for collecting at least one of calories and frigories emitted by each of the at least one magnetocaloric element due to the variation in the magnetic field; the electric drive being integrated into the thermal flux generating device with magnetocaloric material ( 10 , 20 , 100 , 50 , 60 , 90 , 200 ) and comprising at least one electric coil ( 14 , 24 , 55 , 65 , 97 , 205 ) equipped with a winding supported by an armature ( 16 ) and supplied with electric current so as to generate the variation in the magnetic field which causes the movement of a mobile assembly ( 12 , 22 , 52 , 62 , 96 , 204 ) that supports the magnetic arrangement; the at least one magnetocaloric element ( 13 , 23 , 56 , 66 , 99 , 207 ) being located directly adjacent to the magnetic arrangement and positioned in an air gap formed by at least a first space (E 1 ) delimited radially between the magnetic arrangement and the armature ( 16 ) of the electric coils.
