Abstract
The paper provides the results of research, scientific, designing and engineering activity of the
Institute of Thermoelectricity aimed at creating thermoelectric modules of increased
reliability. The activities in this field are based upon the theory of thermoelectricity developed
by the Institute using methodology of mathematical statistics, probability theory, microscopic
theory of degradation processes occurring in thermoelectric material and near-contact areas.
Variations in the design of thermoelectric cooling modules with lifetime of 20 years and
generator modules with lifetime of 10 years are described. The paper illustrates that failure
rate (probability) of these modules is 2 – 5 orders reduced (depending on the design) in
comparison with standard module while weight, overall dimensions and power characteristics
are preserved.
Examples of using highly reliable modules in the systems of air conditioning in vehicles,
space-purpose devices, thermoelectric generators utilizing low-potential waste heat in
industry, power and transportation systems are given.
