在本文中，我们描述了一种新的热电发电机（TEG）分析物理模型。该模型包括汤姆逊效应、珀耳帖热、焦耳热的参数化以及所有热阻和电阻。提出了几何优化和珀耳帖热和热源影响的研究，以及散热器条件和负载电阻对输出功率的影响。将结果与市售热电发电机的测量值和基本热力学极限进行比较。执行生成器之间的比较。
In this paper we describe a new analytical physical model for thermoelectric generators (TEGs). The model includes the Thomson effect, the Peltier heat, a parameterization of the Joule heat, as well as all thermal and electrical resistances. Geometry optimization and investigations of the influence of Peltier heat and the heat source, as well as heat sink conditions and the load resistance, which affect the output power, are presented. The results are compared with measurements of commercially available thermoelectric generators and the fundamental thermodynamic limit. A comparison between the generators is performed.
