Abstract

Thermoelectric generator, which is known as using Seebeck effect, have been widely applied in many industrial parts, for instance, from submarine to equipments capable of producing hot or cooling water. Its usefulness was verified in terms of producing electric power using temperature difference and vice versa. Application on thermoelectric generator has been mainly forced on exhaust gas of automotive engine so far. In this study, the possibility was investigated whether electric power could be produced by using cooling water in automotive engine. As the result, it showed that electric power had differences depending on shapes of power auxiliary apparatus and, in this experiment, maximum of electric power was 1.5 voltage.

제벡 및 펠티에 효과를 이용하는 열발전소자 또는 열전소자는 많은 산업 분야에서 활용되어지고 있다. 특히 군사용으로서 북극 및 남극에서 활동하는 잠수함에서부터 실생활에서 우리가 늘 접하는 냉온수기에 이르기까지 온도차를 이용하여 전력을 생산하거나 또는 전력을 투입하여 온도차를 발생시키는 장치의 효용성은 충분히 입증되었다고 할 수 있다. 자동차 분야에서 제벡효과를 이용한 열발전소자의 활용은 주로 고온의 배기가스를 이용하는데 집중되어 왔다. 본 연구에서는 자동차 내 엔진을 냉각 시킨 후 배출되는 고온의 냉각수를 활용하여 보조전력을 생산할 수 있는 가능성을 조사하였다. 그 결과 전력보조장치의 형태에 따라 전력생산량이 다르며 본 실험에서는 최대 약 1.5 V를 나타내었다.
