提出了一种由发射器和接收器组成的不可逆近场电致发光制冷机（INFER）的新模型，该模型考虑了冷端、热端和贮液器之间的传热。基于脉动电动力学，推导了INFER的冷却功率密度（CPD）和冷却性能系数（COP）的两个临界公式。研究了INFER的最佳热力学特性。同时，讨论了真空间隙对INFER性能的影响。通过在CPD和COP之间进行折衷，给出了参数优化设计准则。计算并比较了同质结和异质结结构的参量特性。确定了最佳设计结构。所得结果可为固体制冷机的优化设计和实际开发提供指导。
A novel model of the irreversible near-field electroluminescent refrigerator (INFER) composed of an emitter and a receiver is proposed, where the heat transfers between the cold and hot sides and the reservoirs are taken into account. Based on the fluctuation electrodynamics, two critical formulas for the cooling power density (CPD) and cooling coefficient of performance (COP) of the INFER are derived. The optimum thermodynamic characteristics of the INFER are studied. Meanwhile, the effects of the vacuum gap on the performance of the INFER are discussed. By making a trade-off between the CPD and the COP, the parametric optimum design rules are presented. The parametric characteristics for homojunction and heterojunction structures are calculated and compared. An optimum design structure is determined. The results obtained here may provide some guidance for optimally designing and actually developing solid-state refrigerators.
