Design of Shared Temperature Difference Type High-Density Integrated Transverse Thermoelectric Generator
摘要: 本文基于低温共烧陶瓷工艺(LTCC)，提出一种短距离热驱动热电臂高密度集成的横向热电发电器(TEG)结构。为了实现TEG的最大化集成，所提出的器件采用冷热源交错分布的共享温差异构发电单元，热电偶进行短距离热驱动，构成热–电通路空间正交协同网络，实现纵向热流和横向电流的同步传导。同时，在冷热源之间设计了集成针孔的铝基板定向热驱来提高能量收集能力。实验结果表明在温差为80 K时，热电偶密度为12对/cm2的横向TEG最大输出电压为46.7 mV，并且最大输出功率因子为10.42 µW/cm2。与双层非接触式型TEG相比，发电能力提高了61.31%。该设计为未来高性能、紧凑型热电能量转换器件提供参考。
Abstract: Based on the Low Temperature Co-Fired Ceramic (LTCC) technology, this paper proposes a transverse thermoelectric generator (TEG) structure with high-density integration of short-distance thermally-driven thermoelectric arms. To achieve the maximum integration of the TEG, the proposed device adopts a shared temperature difference configuration of alternating cold and hot sources for power generation units, and uses thermocouples for short-distance thermally-driven, forming a spatial orthogonal cooperative network of heat-electric pathways to achieve synchronous conduction of longitudinal heat flow and lateral current. Meanwhile, an integrated aluminum substrate with needle holes is designed to provide directional thermal drive between the cold and hot sources to enhance the energy collection capability. Experimental results show that at a temperature difference of 80 K, the maximum output voltage of the transverse TEG with a thermocouple density of 12 pairs/cm2 is 46.7 mV, and the maximum output power factor is 10.42 µW/cm2. Compared with the double-layer non-contact type TEG, the power generation capacity has increased by 61.31%. This design provides a reference for future high-performance and compact thermoelectric energy conversion devices.
