外文摘要：Magnetocaloric refrigeration demonstrates environmental friendliness and high efficiency, and is widely recognized as a promising substitute for vapor compression refrigeration. However, the heat transfer fluids present in traditional magnetocaloric refrigerator limits temperature gradient and lowers the cooling power. Herein, this paper proposes a reciprocating fully-solid-state magnetocaloric refrigerator. The specially designed double-layer structural enables the spontaneous completion of heat regeneration process. The heat-transfer configurations inside or between magnetocaloric materials have been optimized to explore the optimal cooling performance. The heat transfer model has been validated by experiments. The finite element simulation results show that by using gadolinium as magnetocaloric material and the applied magnetic field is 1.0 T, a maximum no-load temperature span of 43.10 K is achieved at the triangle internal heat-transfer configuration, the Peltier's input voltage of 0.5 V and contact time of 30 s. The integrated Peltier system exhibits a markedly lower energy-cost ratio, which reveals sufficient potential for practical application. In addition, the proposed improvements are beneficial for guiding the design and optimization of solid-state magnetocaloric refrigerators.
