Patent ID: 8881537

Claim:
A heat generator ( 1 , 10 ) comprising: at least one thermal module ( 1 ′, 10 ′) containing at least two adjacent magnetocaloric elements ( 2 ) arranged for being passed through by a heat transfer fluid, a common distribution chamber ( 3 ) being associated with a heat transfer fluid circulation means ( 4 ) fluidly connecting the adjacent magnetocaloric elements ( 2 ) and two end chambers ( 5 , 6 ) also associated with a circulation means ( 7 ) with each other and fluidly connected respectively with the magnetocaloric element ( 2 ) located at the ends of the thermal module ( 1 ′, 10 ′) which are a hot end ( 9 ) and a cold end ( 11 ), a magnetic arrangement of the heat generator ( 1 , 10 ) subjecting each magnetocaloric element ( 2 ) to a variable magnetic field to create alternately, in each magnetocaloric element ( 2 ), a heating cycle and a cooling cycle, and circulation of the heat transfer fluid through the magnetocaloric elements ( 2 ) being ensured by the circulation means ( 4 , 7 ), in synchronization with the variation of the magnetic field, wherein the circulation means ( 4 ), associated with the common chamber ( 3 ), displaces the heat transfer fluid simultaneously through the two adjacent magnetocaloric elements ( 2 ) in different circulation directions.
