Patent ID: 7650756

Claim:
A device ( 1 a - c ) for the generation of thermal units using magnetocaloric material, the device comprising: at least one magnetic element ( 2 a - c ) intended to generate a magnetic field, at least one magnetocaloric element ( 4 a - c ) intended to be alternatively subjected to the magnetic field in order to generate calories and frigories, at least one circuit ( 5 ) for circulating a thermal exchange fluid flowing through the magnetocaloric element ( 4 a - c ) to recover at least part of at least one of the calories and frigories that the magnetocaloric element ( 4 a - c ) emits, the circuit ( 5 ) being coupled to means for circulation ( 6 ) of the thermal exchange fluid and to at least one heat exchanger ( 7 , 8 , 78 ) for transfer of at least part of at least one of the calories and frigories recovered by the thermal exchange fluid, wherein the magnetic element is an electromagnet ( 2 a - c ) coupled to at least one power supply ( 3 a - c ) controlled by at least one control unit ( 20 ) for generating electric pulses ( 9 a - c ) and creating an impulsive magnetic field, with the electric pulses ( 9 a - c ) having an intensity (I), duration (t) and frequency (T) triggered as a function of at least one predetermined pulse parameter, and the device comprising at least one thermal sensor ( 10 ) for determining the temperature of the thermal exchange fluid, and said fluid temperature defining at least one pulse parameter.
