Design of a thermoelectric module test system using a novel test method

In this paper we report on the electrical, thermal, and mechanical characterization of segmented-leg PbTe-based thermoelectric modules. This work featured a thermoelectric module measurement system that was constructed and used to measure 47-couple segmented thermoelectric power generation modules fabricated by Tellurex Corporation using n-type Bi 2 Te 3Àx Se x to Ag 0.86 Pb 19+x SbTe 20 legs and p-type Bi x Sb 2Àx Te 3 to Ag 0.9 Pb 9 Sn 9 Sb 0.6 Te 20 legs. The modules were measured under vacuum with hot-side and cold-side temperatures of approximately 670 K and 312 K, respectively. In addition, the measurements on the PbTe-based materials are compared with measurements performed on Bi 2 Te 3 reference modules. Efficiency values as high as 6.56% were measured on these modules. In addition to the measurement system description and the measurement results on these modules, infrared images of the modules that were used to help identify nonuniformities are also presented.

“…The concept of the thermoelectric (TE) defines the direct transformation between thermal energy and electrical energy. This transformation is performed by the TE semiconductors most efficiently [1,2]. TE modules are obtained by connecting tens of P and N type of TE semiconductors as electrically serial and thermally parallel [3,4].…”

“…Thus, while the one surface is cooling, the other surface is heating. If the heat energy that occurred in one surface is sinked by using a fun or another device, the temperature of the cooling surface can be reduced further [1]. TE modules have many advantages which are silent operation, being durable, small size and practical applicability.…”

“…The output parameters of TE module have been calculated by measuring the amount of current that passes through the module, the value of voltage that consisted in the module terminals, the value of the EMK and the value of heated surface temperature of any TE module using the newly devised measurement method by Ciylan and his friends. A system which has microcontroller control system has been implemented to measure and calculate of these values [1,[12][13][14]. The dynamic output parameters of any TE module which is in a working condition can be obtained by using this implemented system.…”
