A finned heat exchanger is an innovative thermal device designed to enhance heat transfer efficiency between two fluids, typically air and a liquid. By incorporating extended surfaces or fins, these heat exchangers significantly increase the surface area available for heat transfer, allowing for improved thermal performance in compact designs. Finned heat exchangers are widely used in various applications, including HVAC systems, refrigeration, and industrial processes where efficient heating or cooling is essential. The fins, which can be made from materials such as aluminum or copper, facilitate better heat dissipation or absorption by promoting turbulent flow, thus enhancing the interaction between the fluids.
