Thermoelectric Generators Current Intensifiers

Abstract

The materials of the article included the following questions: operation of the FLEXTEG module in the thermoelectric generator mode; effects accompanying the thermoelectric generator and its current-voltage characteristic; the discussion of the results. The energy balance of thermal currents is estimated using the Seebeck and Thomson effects, as well as electric currents in the circuit -Peltier, and Joule-Lenz when changing the direction of their circulation. An isotropic design of a module of heat and power generators installed on an envelope flexible plate with different weights is obtained, which increases before the inflection line and decreases after it; in this case, the properties of semiconductors are independent of their location on the flexible plate. A reduction in the influence of a traveling electromagnetic bending wave on its deformation in a flexible plate has been achieved by distributing the weight of thermoelectric generators on the surface of the plate. The main factors influencing the properties of semiconductor materials and operating parameters of thermo-electric generators are estimated. The current-voltage characteristic of a thermoelectric generator with patterns of change in the intervals of voltage (0-6.0 V), current strength (0-1.4 A), power (0-4.0 W) at various temperature gradients (5, 0-105 °C), while the efficiency of thermoelectric generators was 84.0 %.
