摘要
分析了温差发电装置的内部结构对温差发电效率的影响，并在此基础上设计制作出了一种新型温差发电装置，其内部换热通道的横截面为六边形、通道内部带有错排扰流片。通过错排结构使温度差值变大，提高了传热效率。在发动机转速为3000r／min、换热通道入口处尾气温度为130-140℃时，其电压在1．112-1．151V范围内波动，发电功率为1．325W。并通过温度一电压的函数模拟，
The paper analyzed the influences of internal structure of thermoelectric generator on the thermoelectric generation efficiency and on this basis designed and developed a kind of new-model thermoelectric generator. For the newmodel thermoelectric generator,the cross section of its internal heat transfer channel was designed as hexagon and the staggered spoiler was arranged inside the channel. The stagger arrangement can increase the temperature difference and improve the heat transfer efficiency. The results from the relevant experimental study on the new structure show that as the engine speed being of 3 000 r / min and the exhaust gas temperature at the inlet of heat transfer channel being of 130 ℃,the voltage will fluctuate within the scope of 1. 112 V ~ 1. 151 V and the generation power will be 1. 325 W. In addition,by ways of the temperature-voltage function simulation,it is concluded that the temperature and voltage will be proportional to each other in the corresponding temperature.
