Abstract:
-The Thermoelectric Generator (TEG) is a multi-couple semiconductor transducer device which follows the concept of the Seebeck Effect. These devices are usually constructed as plates. Electrical energy is generated through introduction of heat; the amount of energy generated depends on the temperature difference between the cold side and hot side of the said transducer. The study aims to characterize TEG modules which include various electrical configurations, and mechanical attachments to the automobile engine exhaust system for the generation of optimal power. A TEG-Based Heat-to- Power Conversion System was developed to aid and monitor the said experimentations. The TEG array is configured to three (3) different electrical connections; namely, series, parallel, and series-parallel. Prior to the actual mobile testing, simulations were performed through an electric heater, with a corresponding mechanical attachment. Extensive procedures were performed to determine the location where to implement the TEG array configurations to the actual automobile engine exhaust system. The temperature at different ‘hotspots’ were profiled to monitor and determine the heat it generates at idle, and at various running speeds. The shape and size of the physical exhaust system components influenced the respective attachment design and feasibility of installation. Actual mobile testing was performed to determine the performance of the mechanical attachment, and the configured TEG array setup while running at various engine speeds.
