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 separates the cup body, and the electricity is generated by temperature 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 efficiency 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. [ABSTRACT FROM AUTHOR]
