Abstract

This paper presents numerical and analytic studies of a reported thermoelectric micro-generator based on LTCC (Low Temperature Co-fired Ceramic) technology. These types of devices are mainly used in energy harvesting applications by converting the waste thermal energy into electrical one. The aim of the performed analysis is to carry out analytical and numerical studies to investigate the electrical output parameters (internal resistance, output voltage and power) of a fabricated thermopile and multilayer generator. As mentioned in the published paper, the first structure of the thermopile contains 30 thick-film silver/Nickel thermocouples connected electrically in series and thermally in parallel on a single LTCC layer whereas the second structure contains 90 thermocouples screen-printed on three LTCC layers. The obtained numerical and analytical results show an average value of error compared to experimental ones of 11% and 16%, respectively. This good agreement with respect to experimental reported data shows that the derived and used FEM model is validated.

基于ltcc的制备TEG的解析和数值分析与验证

本文对已报道的一种基于低温共烧陶瓷技术的热电微型发电机进行了数值和分析研究。这些类型的装置主要用于将废热转化为电能的能量收集应用。所进行分析的目的是进行分析和数值研究，以调查制造热电堆和多层发电机的电输出参数(内阻，输出电压和功率)。正如发表的论文中提到的，热电堆的第一种结构包含30个厚膜银/镍热电偶，在单个LTCC层上以电串联和热并联方式连接，而第二种结构包含90个热电偶，在三个LTCC层上丝网印刷。所得的数值和分析结果与实验结果的平均误差分别为11%和16%。这与实验报告数据吻合较好，表明所建立的有限元模型是有效的。
