1,Principle of thermoelectric power generation:
Semiconductor power generation is a new way of power generation, which is based on the Seebeck effect of thermal energy directly into electricity
Device consisting of a P type and a N type semiconductor device(thermoelectric materials)One side of the other side to maintain at a low temperature, maintained at high temperature, so high temperature to low temperature side side will heat energy and heat generation. The heat energy flows from the high temperature side into the device, and the heat energy is discharged from the low temperature side through the device, a part of the heat energy flows into the device, and the power is changed into electrical energy, and the output DC voltage and current are output. A larger voltage can be obtained by connecting a plurality of such devices.
Thermoelectric material is a kind of functional material which can be directly converted between thermal energy and electric energy through the movement of carriers in the solid. The basic unit of thermoelectric material device is composed of a pair ofpType andnSeries structure of thermoelectric materials. WhenP-nOn both ends of the temperature is not at the same time, as shown in Fig.It is shown that the current will be generated in the circuit, so as to realize the". And when the DC power is passedP-nRight figureIt is shown that, at one end of the heat absorption, heat release at the other end, so as to realize the "semiconductor refrigeration". Thermoelectric materials are mainly used in: thermoelectric power generation, semiconductor refrigeration,3Semiconductor heating,4.Various types of sensors
2,Thermoelectric power generation applications
The semiconductor thermoelectric generator is mainly used in medical treatment, oil field, field, military affairs and so on.AirOther fields. Such as the United StatesInc. TeledyneDeveloped oil field dedicated generators with annual sales of more than $one billion. Another market field of the project is to use the power generation device for solar energy, geothermal energy, industrial waste energy and so on, so that the heat energy can be directly converted into electrical energy. In addition, the semiconductor power module is small in size, light in weight, easy to carry, and can be widely used in scientific experiment, electric manufacture, instrument and meter, etc..
With the development of modern society, protect the environment, save energy more and more, more and more people to consider how to effectively heat the heat source of various solar heat, ocean heat, geothermal energy and industrial waste heat, burning garbage heat on earth into electricity. Therefore, semiconductor thermoelectric power generation technology will be more widely used.
3,Attention to the use of thermoelectric power generation
Between the thermoelectric modules and two metal fins, preferably coated with a layer of thermal grease to facilitate heat dissipation, reduce thermal resistance. Also note that the thermal power generation components to be heated evenly, can not be directly used to barbecue power generation components. In order to make the power generation component to be affixed to the surface of the high temperature object, the temperature of the high temperature surface can not be more than 200 degrees. It must be cold with metal fins, and take the air cooling and water cooling, oil cooling or other cooling measures to ensure to take away the hot surface came from the heat immediately, to keep temperature difference between two power components, improving the efficiency of power generation.
