【 摘 要 】

The thermoelectric power generation module is a device that directly converts thermal energy into electrical energy. It has many advantages such as noise-free, pollution-free, high reliability, long service life and so on. The traditional thermoelectric power generation module has such disadvantages as complicated preparation process, processing pollution, great material wastage, etc. A method for preparing the thermoelectric power generation module has been studied in this article. Firstly, a silver electrode is made on a ceramic substrate, and then the template is placed on the electrode and stacked layer-by-layer with thermoelectric materials following the lamination technique; subsequently it is sintered into a galvanic couple arm and then the thermoelectric power generation module is made after encapsulation. The preparation method is able to effectively avoid the wastage of thermoelectric materials and processing pollution, and is especially suitable for the wide temperature range operation mode. It is also able to exert the best performance of each material segment and effectively improve the working efficiency of the power generation module.
