超薄板主动式磁蓄冷器数值研究（英文）

Numerical investigation of an active magnetic regenerator composed of super thin plates

对板厚为0.1 mm的室温主动式磁蓄冷器进行了数值模拟。在采用水作为换热介质时,该蓄冷器的最大零负荷温跨达到了将近27 K,该温跨和板厚为0.5 mm,采用镓铟锡合金(Galinstan)作为换热介质所达到的最大零负荷温跨接近。在利用率为1.5,孔隙率为0.4,频率为1.0以及10 K温跨的条件下,该蓄冷器所获得了185 W/kg的最大比制冷功率以及1.6的COP。

Numerical investigation of a room temperature active magnetic regeneration（AMR） refrigerator that is made of plate magnetocaloric material（MCM） with thickness of 0.1 mm was made.When water was used as the heat transfer fluid,the results showed that the no load temperature span is about 27 K,which can compare with the regenerator with thickness of 0.5 and Galinstan as the heat transfer fluid.When the utilization,porosity and cycle frequency are 1.5,0.4 and 1.0 Hz,respectively,the maximum predicted specific cooling capacity was about 185 W/kg with the coefficient of performance（COP） about 1.6 at 10 K temperature span.
