TL;DR: In this paper, the effects of the interface material and loading pressure on the thermal contact resistance of a TEG were investigated and analyzed, and it was found that an increase in the thermal resistance of the thermoelectric module was accompanied by an increased average temperature of the module, a decrease in the ratio of the thermal contacts resistance to the total thermal resistance, and an increase of the output power.

Abstract: A unique experimental set-up was fabricated to carry out axial heat flow steady state experiments for the assessment of thermal contact conductance (TCC) at the interface of two materials. Three different materials (copper, brass and stainless steel) were selected for the experiments considering their mechanical and thermal properties. Heat transfer experiments were performed in vacuum environment (0.045 torr) to find out solid spot contact conductance for nominally flat surfaces with different surface roughness (1–5 μm) for each specimen under several load conditions (0.6–15 MPa). A precise estimation of TCC for the interface of sets of similar materials was one of the most important results of this research. The effects of the surface roughness, the material properties and the load conditions (nominal interface pressure) have been studied and documented. Furthermore, the experimental results of solid spot contact conductance were compared with four theoretical models, showing their limitations to make a precise estimation of the TCC in the range of the used parameters.
