Implementación de una unidad didáctica para análisis de transferencia de calor por convección forzada controlada por pantalla táctil

This project has an objective design and executing a didactic unit for analysis of heat transfer by forced convection equipment that will be implemented in the laboratories to the Electromechanical Engineering Career of Technical University of Cotopaxi. As a contribution to theoretical and practical knowledge of students, this project can be used as teaching material for specialties that have related subjects in their study plan. The heat transfer module is a tool that allows obtaining the convection coefficient through experimental practices. The module has electrical and mechanical parts, the mechanical parts being the air inlet and outlet ducts, coexisting with the components of the electrical part such as blower, cartridge type resistance, pyrometer, contactors, thermomagnetic switch, pushbuttons and temperature sensors, fluid velocity. The process of heat transfer gives from a fluid in motion being the blower who sends air through the duct that internally has the sensor elements and this in turn to a cylindrical where a resistance is in charge of producing the dissipation of heat. This data sends to a processor the results obtained through the experimental practice were compared with the results obtained through mathematical expressions expressed by different investigators, resulting in an error lower than 11.2% and 13.50% respectively, which allows validating the module developed in this investigation. It should be noted that thermomagnetic switches protect the entire control system, in order to safeguard the good condition of the equipment.
