摘　　要：温差发电器件是一种利用半导体材料的物理性能,实现热能与电能的直接转换全固态能量转换装置。温差发电器件由于没有运动部件,具有无噪音、无磨损、寿命长、稳定性高等优点。依据塞贝克效应,对温差发电器件的结构进行设计,选用氧化铍陶瓷基片,大大提高单位面积热通量;此外还研究了P/N结对数对温差发电器件的电优值的影响。以提高加工效率和质量为目标,拟定其加工流程,并对温差发电器件的组装过程进行详细说明和组装模具进行了详细设计。为温差发电器件的制作工程应用提供了一定的参考。Thermoelectric power generator is a solid-state device which can convey heat into electric energy with the physical properties of semiconductor materials. Due to without moving parts , TE power generator has merit of no noise, no wear, long lifespan and high stability, etc. The TE power generator was designed according to the Seebeck effect. Beryllium oxide ceramic substrate was selected to improve the efficiency of heat importation. Furthermore, the effect of P/N junction numbers on electric merit of the device was studied. The machining process was formulated to improve the machining efficiency and quality. The assembly mold and process were depicted in detail. The method of design and production of thermoelectric devices provide a reference for the engineering applications.
