Diseño y construcción de un termogenerador de baja carga basado en el uso de una célula Peltier acoplado al sistema de escape de un motor monocilíndrico

Abstract

The objective of this study was to present an alternative for the generation of electrical energy based on a thermal base to seek satisfaction of the excessive demand for energy due to the depletion of fossil fuels around the world and their respective sources. A prototype of a thermal generator was built to be coupled by means of a base attached to the exhaust system of a motorcycle. For which, the requirements to be covered were identified. It was found that it is necessary to obtain a generator of continuous termal energy by taking advantage of the difference thermal that occurs between the heat of the exhaust pipe and the flow of air when circulating through the heatsinks. In the development of the project, an Oromoto single-cylinder motorcycle with a cylinder capacity of 110cc was used to analyze, study and test the feasibility and effectiveness of applying the thermal energy generator by induction of residual heat and cold from the environment. It required 6 series-connected thermoelectric elements and a support base in the motorcycle exhaust system for proper heat and cold induction to obtain the required power output. The energy consuming elements used for the verification of the appropriate generation of energy were headlights, taillights and directional lights of the LED type. Two different tests were carried out to verify the correct operation of the generator. There weren’t inconveniences or damage to the components, or any failure in the connection circuit. In this way, it can be concluded that the prototype is suitable to be implemented in the exhaust system for better use of both heat and cold, and that it is capable of generating enough energy to feed consumers on the motorcycle.
