摘要
对半导体热电堆的发电性能进行了实验研究 ,得出这种半导体热电堆在冷端温度不变的情况下 ,其发电性能与热端温度的关系 ,以及半导体热电堆在热端温度不变的情况下 ,冷端温度对其发电性能的影响 ;发现半导体热电堆作为电源时 ,其内阻对它的性能指标有很大的影响 ,而且内阻随着温度的升高而增大。采用简化的方法从理论上计算了热电堆的特性 。
In this paper,an experiment for generating performance of semiconductor thermoelectric module is carried out,and some useful results are obtained.One is the relationship between generation performance and hot side temperature,when cold side temperature is kept constant.The other is the relationship between generation performance and cold side temperature,when hot side temperature is kept constant.While semiconductor thermoelectric module is used as power supply,inner resistance which is changed with temperature has great influence on its performance.A simplified calculation based on theoretical method is conducted and calculated data agree well with the experimental results.
