Helical fins are a type of heat transfer surface commonly used in various industrial applications to enhance the heat transfer rate between a fluid and a solid surface. These fins consist of a helical coil or spiral structure that is attached to the surface of a heat exchanger or a cooling device, increasing the surface area for heat transfer. The helical shape of these fins provides several advantages over traditional straight fins, such as improved heat transfer efficiency, higher thermal performance, and reduced pressure drop. They are particularly effective in applications where there is limited space available for heat transfer equipment or where the fluid flow is turbulent. Research in the area of helical fins typically focuses on optimizing the design and performance of these fins, understanding the heat transfer mechanisms involved, and developing computational models to predict their thermal behavior accurately. Additionally, studies may also investigate the material properties, manufacturing processes, and cost-effectiveness of helical fins in practical applications.
