热接触会影响热电发电机的输出性能。然而，在一些应用中，热源无法提供足够的加热面积用于热接触。因此，应设计和开发基于优化热接触界面的紧凑型热电发电机。本文设计、模拟、实现和测试了三维热延伸结构，以优化紧凑型热电发电机的热接触界面。结果表明，基于三维热延伸结构的紧凑型热电发电机可以减少热接触面积的要求，并使热流沿着三维结构定向传递到热电模块。在仅 3600 mm2 的热接触面积中，基于三维结构的紧凑型热电发生器可以在 900 秒内产生 5.58 V 和 829 mW。
The thermal contact can influence the output performance of thermoelectric generators. However, in some applications, the heat source cannot afford an enough heating area for thermal contact. Therefore, compact thermoelectric generators based on optimized thermal contact interface should be designed and developed. In this paper, three-dimensional thermal extensional structures are designed, simulated, implemented and tested to optimize the thermal contact interface of compact thermoelectric generators. The result indicates that the compact thermoelectric generators based on three-dimensional thermal extensional structures can reduce the requirement of thermal contact area and make the heat flow directionally transferred to thermoelectric modules along the three-dimensional structure. In only 3600 mm2thermal contact area, the compact thermoelectric generators based on the three-dimensional structure can generate 5.58 V and 829 mW within 900 s.
