半导体热电堆发电的发展及展望

热电发电是一种合理地利用地热、太阳能、海洋能及余热和废热等低势能转换为电能的有效方式。热电发电具有结构简单 ,无噪音、无震动、无磨损 ,运行寿命长 ,组合方便 ,实用面广 ,对热源温度要求低等特点 ,目前在国外已有使用 ,而在国内未见有关研究报道。可以相信随着热电材料的不断发展 ,以及制备工艺的不断完善 ,热电发电的前景会越来越光明。

The Development and Expectation of the Generating Electricity Using the Semi-Conductor Thermopiles

With the development of society and economy, it is necessary for us to adopt various methods to take full advantage of all kinds of energy because of the crisis of energy and environment. Generating electricity by thermoelectricity is a kind of efficient mode using terrestrial heat, solar energy, oceanic energy, surplus heat or deposed heat, which can convert the low potential energy into electricity. And it has many advantages over the traditional mode, such as: simple set, noiseless, none quiver and abrasion, long life span, etc. At present it has been used overseas, but it is seldom reported at home. We think its foreground would be very well with the development of the thermoelectric material and techniques.
