基于液态介质的温差发电串并联实验与仿真研究
摘要:温差发电的发电功率和效率不仅受到温差发电片性能和冷热两端温差的影响,在一定条件下,受其他因素的影响也较大。采用仿真分析、实验论证、理论预测与试验测试相结合的方法,详细研究了多种串并联工况对温差发电片发电效率的影响。将串并联工况分为同并异串、异并同串2种,分别从2种串并联工况研究得出结论:最大功率值的取值条件为,在低温情况下,每行串联个数相同,串联个数与并联行数相同,内外阻值相同;在不同的热端温度条件下,温差片内部热阻以及热端、冷端热阻的变化规律是影响最大功率取值的一个重要因素。研究结果对温差发电片的应用提供了理论支撑。
Abstract:The power and efficiency of thermoelectric generation are not only affected by the performance of thermoelectric generator and the temperature difference between the hot and cold ends, but also by other factors under certain conditions. Therefore, the effect of series-parallel operation on the efficiency of thermoelectric generator was studied in detail by means of simulation analysis, experimental demonstration, theoretical prediction and experimental test. The series-parallel operation is divided into two types: same series with different parallel, different series with same parallel. From the study of three series-parallel operation conditions, it is concluded that there is only one condition for the maximum power value. At low temperature, the number of series is the same as that of parallel operation, and the internal and external resistance values are the same. The internal thermal resistance and the variation of thermal resistance with hot end and cold end are important factors that influence the maximum power value. The research results provide theoretical support for the application of thermoelectric generator.
