Patent ID: 8596077

Claim:
A magneto-calorific thermal generator ( 1 ) comprising: a plurality of thermal elements ( 40 - 43 ) based on magneto-calorific material, magnetic means ( 3 ) for creating a variation in a magnetic field in the plurality of thermal elements ( 40 - 43 ) and for varying a temperature of the plurality of thermal elements ( 40 - 43 ), at least two separate collector circuits, the at least two separate collector circuits comprising a separate, dedicated “hot” collector circuit and a separate, dedicated “cold” collector circuit, in each of which circulates a separate heat transfer fluid arranged to collect respectively one of calories or frigories emitted by the plurality of thermal elements ( 40 - 43 ) according to a functional cycle of the respective plurality of thermal elements ( 40 - 43 ), and means for connecting the at least two separate collector circuits to external circuits destined to use the calories and the frigories collected therefrom, wherein the generator comprises at least one thermal module ( 10 - 13 ) comprising the plurality of thermal elements ( 40 - 43 ) stacked and arranged so as to define and form channels ( 50 ) between each adjacent pair of the thermal elements ( 40 - 43 ), and each of the channels ( 50 ) allows the circulation of the heat transfer fluid, the channels are divided into dedicated hot channels, which circulate the heat transfer fluid of the hot collector circuit, and into dedicated cold channels, which circulates the heat transfer fluid of the cold collector circuit, the hot channels and the cold channels are alternately arranged between the plurality of thermal elements ( 40 - 43 ) such that each thermal element ( 40 ) has, on one side, at least one of the dedicated hot channels and, on another side, at least one of the dedicated cold channels, and each of the plurality of thermal elements ( 40 - 43 ) have inlet orifices ( 51 ) and outlet orifices ( 52 ) for fluid which communicate so as to distribute a flow of heat transfer fluid in each hot and cold collector circuit, respectively, into the corresponding hot and cold channels ( 50 ).
