并联与串联连接温差发电效率研究

摘要

温差发电是一种废弃能量回收利用的巧妙方法；放置于汽油机尾气排放管附近温差发电片热端温度为77益。使用此热源进行温差发电，4块发电片并联连接发电效率为3.2W高于串联连接的1.9W；增加发电片至8片，并联与串联发电效率均增加，但是由于内阻增加发电效率增加不足2倍。%Temperaturegeneration is a kind of recovery way of waste energy, gasoline engine exhaust pipe temperature is 77℃. The generation efficiency is 3.2W of the 4 piece power parallel connection of the temperaturegeneration by this heat source, it is higher than 1.9W of series connection. When the power generation is increased to 8 pieces, parallel and serial power generation efficiency will also increase, but because of the increasing of internal resistance, the generation efficiency is less than 2 times.
