ОТРИМАННЯ ЕЛЕКТРИЧНОЇ ЕНЕРГІЇ ВІД БАТАРЕЇ ОПАЛЕННЯ

Abstract

As a result of the analysis of the research results, the volt-ampere characteristic of the Peltier element used in the mode of temperature difference generation and the dependence of the temperature difference on the "hot" and "cold" surfaces on the consumed electric power were obtained. It is determined that the efficiency of the element decreases with increasing power consumption, when when a significant temperature difference is reached, the element between the heated and cooled surfaces can not sufficiently perform the functions of thermal insulation. It has been experimentally determined that it is expedient to use Peltier elements in the temperature range when the difference is from 13 to 25 ° C, and this is possible in the presence of an effective mechanism of heat dissipation from the hot side. Thus, when developing devices with thermoelectric cooling, it is advisable to choose the optimal mode of operation with a voltage below the nominal. The work of the element was experimentally tested on the basis of EMF determination for one element of TPP 1– 12706. The experimental dependences of the plate and radiator temperature on the generated EMF for the Peltier element TPP 1 - 12706 were obtained. and quality of TE devices. The scientific novelty of the work is to confirm the possibility of creating a heat generator using as a source of energy available in everyday life temperature difference, in particular, the dependence of the generated EMF on the temperature difference between "hot" and "cold" side Peltier TPP 1 - 12706 The practical significance of the work lies in the possibility of using the device in domestic conditions when using a battery with heating to obtain electricity that can be used to connect a flashlight, humidifier device, charge the phone.
