An Investigation on the Coupled Response of Vehicle Skutterudites-Based Thermoelectric Module

Abstract:

Basing on that skutterudites-based thermoelectric module may be applied to the vehicle exhaust power generation system, a multi-field of thermal mechanical-electrical coupled model was established and investigated by finite-element method. The thermal stresses, open circuit voltage, output power and conversion efficiency of thermoelectric module (TEM) are calculated and obtained. The service environment is simulated with the hot side temperature data obtained by experimental measurements. An independent tank is adopted on the cold side, to develop a temperature difference for electric producing, and then achieve the thermoelectric conversion. By analyzing the working properties of TEM, the mechanical properties and thermoelectric characteristics are also discussed, which provides guidance for TEM practical application.
