Theresults of computer design and optimization of thermoelectric“liquid-liquid” systems for thermoelectric generators and coolershave been presented. The information on the optimized series of such systems isgiven.

Special emphasis is given to achievement of maximum efficiency,coefficient of performance and reliability values. Special heat-exchangedevices have been developed, including those functioning with the use ofcorrosive heat-exchange media. Special thermoelectric modules have been createdimproving MTBF of thermoelectric systems by a factor of 80-100.
