Thermoelectric generator Thermoelectric performance test is what? Thermoelectric performance testing of thermoelectric generators involves the fields of applied electronics and thermal technology. The utility model is characterized in that the utility model comprises an electric heating heat source unit which is attached to and heated on the hot surface of the thermoelectric generator.
The circulating cooling water circuit radiator unit is close to the cold surface of the thermoelectric generator and cools the cold surface of the thermoelectric generator; Collect the temperature of the thermoelectric generator hot side and cold side, the current and voltage output of the thermoelectric generator, the flow rate and liquid temperature of the radiator unit of the circulating cooling water loop, process and analyze the above data, and output the control signal to the data acquisition and data processing unit of the electric heating heat source unit. The system measures the thermoelectric performance of the whole thermoelectric generator. The measured data directly reflect the whole performance of the thermoelectric generator, which has the characteristics of simple structure and strong adaptability.

Thermoelectric generator Thermoelectric performance test as an important energy conversion material, thermoelectric materials are widely used in aerospace, national defense, military, biomedical, electronic technology and many other fields. In the research process of thermoelectric materials, besides the preparation of new materials by new methods, the characterization of thermoelectric properties of materials is also an important link. At present, the thermoelectric properties are mainly characterized by Seebeck coefficient, resistivity and thermal conductivity. Seebeck coefficient and resistivity are both electrical parameters and can be measured simultaneously, while thermal conductivity needs to be measured separately. The measurement of Seebeck coefficient and resistivity can not only characterize the thermoelectric transport properties of materials from a macroscopic point of view, but also indirectly reflect micro properties such as carrier concentration and mobility. Therefore, the study of thermoelectric performance test of thermoelectric generator is of great significance.
