Abstract

Authors have methodically investigated the alternative energy technologies based upon thermoelectricity generation. Firstly, its power is systematically investigated under various work conditions in thermoelectric applications. In addition, they have modeled, designed, and constructed the thermoelectric power system. Moreover, they have invented a state-of-the-art table-top instrument that may evaluate several critical thermoelectric characters in situ. Several aspects of the thermoelectric features are characterized in situ that include the efficiency, force response curve, current-voltage (i.e., I-V) curve, power-voltage (P-V) curve, and the power versus temperature (P-T) responses. Furthermore, they have successfully built a high-power heat harvester and have applied to the automotive case study in details. Finally, they have obtained the multi-stack thermoelectric devices that have improved characters; e.g., both the power output and the thermoelectric efficiency have improved in comparison to the devices commercially available. The investigation leads to 19+% efficiency in triple stack devices and 10+% in dual-stack.
大功率热电发电的系统研究
作者系统地研究了以热电发电为基础的替代能源技术。首先,系统地研究了热电应用中各种工况下的功率。此外,他们还对热电动力系统进行了建模、设计和构建。此外,他们还发明了一种最先进的台式仪器,可以原位评估几种关键的热电特性。热电特性的几个方面被就地表征,包括效率、力响应曲线、电流-电压(即I-V)曲线、功率-电压(P-V)曲线和功率-温度(P-T)响应。此外,他们还成功构建了大功率热采集器,并将其详细应用于汽车案例研究。最后,他们得到了性能得到改善的多层热电器件;例如,与商用设备相比,功率输出和热电效率都有所提高。研究结果表明,三层器件的效率为19%以上,双层器件的效率为10%以上。
