Thermoelectric generator modules and blocks

Abstract

Characteristics and elements of a new type structure of thermoelectric modules for electric power generation with output power of 10 W have been presented. A parametric series of the indicated modules with rated output voltage of: 0.2; 0.4; 0.8; 1.6; 3.2 and 6.4 V is proposed. Modules are designed for the use in thermoelectric generators of different purposes along with heat sources use that provide operation temperature level of the module warm side of 250-300/spl deg/C. Optimization methods of known thermoelectric materials for the indicated modules conversion efficiency at a level of more than 6% have been examined. The study results of commutations and anti-diffusion layers new types effect on the modules lifetime and resistance to climatic and temperature action have been given. The reliability investigation results of the module as a whole are presented. Examples of modules with heat exchangers arrangement into functional blocks that provide a user necessary overall dimensions and electric parameters for current and voltage are also presented. Variants of specific applications of modules and blocks in thermoelectric generators with catalytic heat sources have been examined.
