Abstract

An optimal design and parametric study of a heat spreader applied to a thermoelectric generator attached to a larger chimney plate is presented. The thermoelectric module consists of a hot plate, a spreader, a thermoelectric generator and a cold plate based on water cooling. A three-dimensional thermoelectric generator model is proposed and solved numerically using a control volume based finite difference formulation. The objective is to obtain efficient power output balancing with reasonable material costs. A simplified conjugate-gradient method is used to search for the optimum length and height of a spreader ranging from 30 mm < L sp < 200 mm and 1 mm <H sp < 15 mm for different gas heat transfer coefficient. The results show that the Pareto front indicates a trade-off between the power output and the material of the spreader consumption.
