New System

A new system for converting combustion heat into electric power was proposed on the basis of countercurrent burner with thermoelectric element embedded in a wall separating incoming fresh mixture and combustion products. The wall serves as heat exchanger between combustion products and the fresh mixture. Numerical simulations showed that almost whole combustion heat may be transferred through the thermoelectric element in such system and the total thermal efficiency attained a value close to the conversion efficiency of the thermoelectric device itself.

The potential for automotive exhaust heat based thermoelectric generator (TEG) has been increased with continuously advances in thermoelectric technology. The thermal performance of the heat exchanger in exhaust-based TEG was analyzed. In terms of interface temperature and thermal uniformity, the thermal characteristics of the heat exchangers with different internal structures, materials and thicknesses were discussed. CFD simulations and infrared experiments on a high-performance production engine with a dynamometer were carried out. It was proved that the plate-shape heat exchanger made of brass with internal baffles and the thickness of 3mm, obtained a relatively optimal thermal performance, and it will help to improve the thermal performance of the TEG.

Automobile Exhaust Thermoelectric Generator

The output performance of Automobile Exhaust Thermoelectric Generator (AETEG) is related to the temperature difference and electric connection topology of thermoelectric modules, in order to decrease the ring current among the thermoelectric modules in parallel with different temperature difference and enhance the output performance, a novel heat exchanger using in AETEG is designed in this paper. The interior structure of heat exchanger with fishbone is analysed, then its surface temperature distribution is simulated with ANSYS software and experimented with thermal imaging instrument. Both of the results show that the surface temperature distribution of the fishbone heat exchanger designed in this paper is more uniform in lateral direction and dispalys an obvious gradient in fore-and-aft surface, compared with the one of cavity designed before, the novel heat exchanger has overwhelming advantage in the output performance of AETEG, and the method adopted in this paper is feasible and practical.
