Thermal dissipation efficiency is a determining factor in the performance of various engineering systems. This book presents the development and analysis of a didactic bench for the study of heat transfer through fins of uniform circular cross-section. The research investigates, through detailed experiments, the influence of variables such as material, thermal conductivity and geometry on heat exchange efficiency. The results obtained were compared to analytical models, allowing the methodology employed to be validated and providing a valuable tool for teaching and research in the field of thermal engineering. Essential reading for students, teachers and professionals interested in the practical application of heat transfer concepts.
