摘　　要：温差发电是一种绿色环保的发电方式。它是基于热电材料赛贝克效应的一种发电技术。处于高温端的热电材料空穴(电子)浓度高于低温端,在浓度梯度的作用下,空穴和电子向低温端扩散,从而形成电流。热电材料通过这种方式直接将热能转换成电能。因此温差发电片工作时具有无运动部件,无噪声,无污染物排放,使用寿命长等特点。笔者通过研究温差发电原理,设计了一种涂布机排风管废热温差发电装置。Power generation,by the use of temperature difference,based on the Seebeck effect is an environment friendly way to convert heat to electricity.The high temperature part of a thermoelectric material has a higher carrier concentration than that of low temperature part,such concentration gradient will produce the current when the carrier diffuses from high temperature part to low.Hence,thermoelectric materials can directly interconvert thermal power to electricity,and the relevant devices have the advantages of no moving part,quiet,no pollution and long service life.In this study,we designed a thermoelectric power generator to recycle the waste heat which can be used on the exhaust air duct of a coating machine.
