摘要
建立了半导体温差发电器件的基本模型,推导出器件等效导热系数的数学表达式,发现其与N型、P型半导体材料及两端陶瓷片的导热系数紧密相关,对半导体材料和陶瓷片的导热系数随温度的变化关系进行了实验研究并进行了数值拟合,绘制了器件等效导热系数与温度的曲线,得到的计算值与实验结果基本吻合。
A basic model of semiconductor thermoelectric generator was constituted. Based on the model, the expression of thermoelectric generators thermal conductivity was derived, which is closely associated with the thermal conductivity of N type semiconductor, P type semiconductor and ceramic plate. Experimental research on the relationship between temperature and thermal conductivity was preceded, and curves about the relationship were plotted. Result indicates that theoretical value is approximate with experimental data.
