本文通过对半导体制冷器△T—I关系在最佳电流处的曲率的研究,发现这种制冷器的敏感特性和输入功率都与曲线在最佳电流处的位置和曲率有关;同时曲率本身又与制冷器的设计参量(面长比A/l)和材料参量(比值k/p)有关。这表明在制冷器设计时,必须考虑到这两个参量的影响,才能尽可能地发挥材料的潜力和保证设计更为合理。

In this paper, we study the relationship between △ T-I and the best current of the semiconductor cooler and find that the sensitivity and input power of the refrigerator are related to the position and curvature of the curve at the optimal current. At the same time, the curvature itself And the design parameters of the refrigerator (face length than A / l) and material parameters (ratio k / p). This shows that in the design of the refrigerator, the influence of these two parameters must be considered in order to exert the material potential as much as possible and ensure that the design is more reasonable.
