摘　　要：在实验研究单段式结构赝三元材料的热电模块基础上,利用现有半导体致冷器生产工艺,依据热电材料的温度特性和冷热端工作温度,采用不同电阻率的赝三元材料,设计制作了两段式结构的热电模块.研究表明,当冷、热端工作温差为80K时,其输出功率和发电效率均比单段式结构的热电模块提高80%左右.Based on experiments ana researches of monolithic thermoelectric module of quasi-ternary material, two-stage segmented one is designed and fabricated using the existing producdon technology of semiconductor freezer, employing quasi-ternary materials with different resistance rate, and according to temperature character of thermoelectric material and work temperatures of cold end and hot end. When the difference of temperature between cold end and hot one is 80k, both its output power and generation efficiency are 1. 8 times more than single-section one' s.
