摘　　要：采用"一杯两体"结构成功制作出冷热分离式高效温差发电杯,相较于传统温差发电杯,其发电效率大幅提高。通过采用"一杯两体"结构将杯体一分为二,一体盛放热水;另一体盛放冷水,温差发电片置于将杯体隔开的导热隔板中,利用冷热水温差进行发电,同时冷水也用于散热,由此克服了传统温差发电杯散热性能差的缺陷,从而使得温差发电片的电阻不会大幅增加,大幅提高了温差发电杯的发电效率。另一方面,"一杯两体"结构可满足人们对不同温度的饮用水的需求。By using a ＂one cup with two spaces＂ structure, a hot and cold separation type high temperature thermoelectric generating cup is successfully manufactured. Compared with the traditional thermoelectric generator cup, the power generation efficiency is greatly improved. By using the ＂ one cup with two spaces＂ structure, the cup body is divided into two parts, and the one part is filled with hot water, the other is filled with cold water. The thermoelectric generator is arranged in a heat conducting clapboard which separatesthe cup body, and the electricity is generated bytemperature difference of the cold and hot water, and the cold water is also used for heat dissipation. Thereby, the defects of e traditional thermoelectric generator cups are overcome, the resistance of the thermoelectric generation chip is not increased greatly, and the generation efficieney of the thermoelectric generating cup is greatly improved. On the other hand, ＂ one cup with two spaces＂ structure can satisfy people＇ s demand for drinking water with different temperatures.
