| 摘要 |
The invention relates to a magnetocaloric thermal generator (10) comprising a primary circuit (P10) fluidically connecting two stages (E1, E2) of magnetocaloric elements (M11, M12, M21, M22) using a heat-transfer fluid referred to as primary fluid flowing alternately back and forth, said stages (E1, E2) being subjected to the variable magnetic field of a magnetic system (2), and the primary circuit comprising a cold side (F) and a hot side (C) at which the magnetocaloric elements (M11, M12, M21, M22) of said stages (E1, E2) are fluidically connected. At least the cold side (F) of the primary circuit comprises an outlet point (S1) connected to another point of the primary circuit, referred to as the injection point (I1), of the hot side (C) by a bypass pipe (D1) allowing the primary fluid to be displaced only from the outlet point (S1) toward the injection point (I1). Another subject of the invention is a method of cooling said secondary fluid using said magnetocaloric thermal generator. |
