Keywords:

The paper describes the equipment for studying the parameters of thermoelectric generator modules Altec-10002, developed at the Institute of Thermoelectricity (Ukraine). The results of experimental studies on generator modules with a reduced height of the thermoelement legs that make up the module are presented. It is shown that the height of the legs can be reduced 1.5 – 2 times without a significant decrease in the module efficiency. In this case, the reduction of the height of the legs is hindered, first of all, by the increasing influence of the thermal resistance of the heat spreaders between the module and the surfaces of the heat source and heat sink.
