Finite Element Evaluation of the Strength of Silicide-Based Thermoelectric Modules
发布日期 2016
Silicide-based thermoelectric modules (TEMs) for power generation operate at mid-high temperature range. In the operating conditions, thermal stresses in materials with different coefficient of thermal expansion may reduce the mechanical strength of the modules. In this work, a finite element evaluation of the mechanical strength of a 16 legs thermoelectric module prototype operating with 300 K temperature difference is presented. Mohr-Coulomb failure criterion for thermoelectric legs and von Mises yield criterion for the connections were considered. Failure of thermoelectric materials was found to occur on the hot side, near the ceramic layer. This was also highlighted by IR Thermography on a tested prototype.
