摘要/Abstract

摘要： 为了最大化建立汽车尾气热电转换装置的温差，在相同热源条件下通过测试整体式、单列式和独立式3种冷源结构下不同发动机负荷时的开路电压和最大输出功率，分析了3种冷源结构对系统输出性能的影响.结果表明：优化冷源结构可以明显提高汽车尾气热电转换装置的性能；独立式冷源结构的效果最好，单列式其次，整体式最差；单个热电器件的冷面采用独立式的小型化冷源结构可以保证它们之间有更好的接触和更大的温差.

Abstract: To maximize the temperature difference of automobile exhaust thermoelectric generator(AETEG), based on the same hot source and different loads of engine, the open circuit voltage and maximum power of AETEG with unitary, singlecolumn and independent cold source structure were experimented, the effect of those different cold source structures on the output performance of AETEG was compared and analyzed. The results indicate that the output performance can be greatly enhanced with the optimized cold source structure, the effect of independent cold source structure is the most superior, singlecolumn cold source structure takes the second place, while the unitary cold source structure is the worst, the contact between the cold side of single thermoelectric module and its corresponding cold source is tighter, and the temperature difference is much larger when cold source structure is of independent miniaturization.

Key words: automobile exhaust thermoelectric generator, cold source structure, output performance, thermoelectric module
