Abstract (en)
[origin: WO2011135205A1] The present invention relates to a method for generating a thermal flow from at least one thermal module (1) comprising at least two magnetocaloric elements (21, 22, 23, 24) which are connected two-by-two, through which a heat transfer fluid flows, and which are exposed to a variable magnetic field, wherein the heat transfer fluid circulates simultaneously through said elements (21, 22, 23, 24) in a manner synchronized with the variation in the magnetic field. Said method is characterized in that it consists, in addition, in exposing alternating elements of said elements (21, 22, 23, 24) to an opposite variation in the magnetic field, in causing the heat transfer fluid to circulate simultaneously and in opposite directions in said elements (21, 22, 23, 24), in such a manner that the fluid flowing out of one of said elements (21, 23; 22) at the end of a heating phase is circulated during the following phase in the following element (22, 24; 23) exposed to heating, as well as in that the fluid flowing out of one of said elements (22, 24; 23) at the end of a cooling phase is circulated during the following phase in the following element (21, 23; 22) exposed to cooling, and conversely, and in storing, between two magnetically opposite phases, the heat transfer fluid in an intermediate receiving area (81, 82, 83, 91, 92, 93). The invention also relates to a thermal generator implementing said method.
