磁热热发生器
摘要：
本发明涉及一种磁热热发生器(1)，其包括：至少两个磁热元件(2、12)，所述磁热元件相继地设置并且形成至少两个相继的热级，所述磁热元件被分开的载热流体穿过，并且每个所述磁热元件包括两个相对的端部(3和4、13和14)；一个磁装置，所述磁装置用于使每个所述磁热元件(2、12)经受变化磁场，在每个所述磁热元件(2、12)中交替产生加热周期和冷却周期；一个载热流体的驱动部件(8)，所述载热流体的驱动部件驱动所述载热流体按与所述磁场的变化同步的方式、交替地向一端的方向和向相对的端部的方向并且相反地向所述相对的端部的方向和向所述端部的方向穿过所述磁热元件。所述磁热热发生器(1)的特征在于，所述磁热元件(2、12)在它们的相继端部(4、13)处通过热交换部件(5)两两地热连接，所述热交换部件分别与所述第一磁热元件(2)中流动的载热流体和与在所述第二磁热元件(12)中流动的载热流体接触。
摘要（英）：

The magnetocaloric heat generator (1) comprises at least two magnetocaloric elements (2, 12) arranged in succession and making up at least two consecutive thermal stages crossed by separate heat transfer fluids and comprising each two opposite ends (3 and 4, 13 and 14), a magnetic arrangement intended for subjecting each magnetocaloric element (2, 12) to a variable magnetic field, alternately creating a heating cycle and a cooling cycle in each magnetocaloric element (2, 12), a mechanism (8) for circulating the heat transfer fluids through the magnetocaloric elements alternately towards one end and towards the opposite end and vice versa, in synchronization with the variation of the magnetic field. The magnetocaloric elements (2, 12) are connected thermally two by two at their consecutive ends (4, 13) through the intermediary of a heat exchange mechanism (5) in thermal contact respectively with the heat transfer fluid circulating in the first (2) of the magnetocaloric elements and with the heat transfer fluid circulating in the second (12) of the magnetocaloric elements.
