The inquiry project: the use of electric effect (if both ends of the semiconductor thermoelectric semiconductor temperature difference will produce thermal electromotive force, also called the Seebeck effect) to convert heat energy to electric energy principle.

Brief introduction:
Semiconductor thermoelectric generator demonstrator, teaching demonstration experiment article in secondary technical school Semiconductor thermoelectric generation technology, semiconductor thermoelectric generation technology, its working principle is that in the two different nature of the semiconductor at both ends of a temperature difference, so that the two ends of the semiconductor will produce a DC voltage. Thermoelectric power generation has the characteristics of no noise, long life, stable performance and so on. The utility model can be started quickly in a cold environment with a temperature of 40 degrees Celsius, so that the utility model is applied more and more widely in practice. Thermoelectric generation is a new type of power generation, which uses the West Burke effect to convert heat energy directly into electric energy. A semiconductor generator made with a semiconductor thermoelectric generating module can generate electricity as long as the temperature difference exists. The utility model has the advantages of no noise and pollution, and the service life of the utility model is more than ten years, and is free from maintenance. Therefore, the utility model is a portable power supply with a wide range of applications. Semiconductor thermoelectric generator is mainly used in oil field, field, military and so on. Another market area of the project is the use of power generation equipment for solar energy, geothermal power, industrial waste energy and so on, so that heat energy can be directly converted into electricity. In addition, the semiconductor power generation module has the advantages of small size, light weight and portability, and can be widely used in the manufacture of small household electrical appliances, instruments and meters, toys and tourism. With the increasing demand for environmental protection and energy conservation, the use of thermoelectric generation may be the general direction of development, from small devices to large power plants, and more and more laboratory theory will be applied to practice. On the domestic market, the newly developed semiconductor thermoelectric generator module has the specifications of 40 * 40 * 4 mm, and its internal 0.09 ohm, its resistance is small, high temperature and long life. Fully meet the needs of developing thermoelectric generators. If the temperature difference between the two sides of the component can be maintained at 60 degrees Celsius, the voltage 3.5V can be issued, the current 3A--5A, the temperature difference will be reduced, and the voltage and current will also decrease. Note that when using, between the thermoelectric modules and two metal fins, preferably coated with a layer of thermal grease to facilitate heat dissipation, reduce thermal resistance. In addition, note that the thermoelectric components should be heated evenly and cannot be fired directly with an open flame. In order to smooth the power generation components on the surface of high temperature objects, the high temperature hot surface can not exceed 250 degrees. It must be cold with metal fins, and take the air cooling and water cooling, oil cooling or other cooling measures to ensure the hot surface can pass over the heat.
