In this segment we have discussed about extended fins or surfaces and how the rate of heat transfer is increase by using extended fins instead of unfinned material. We’ve also discussed how various type of extension like parallel rectangle extension, perpendicular extension and curl or spline extension are used to enhance or increase heat transfer from a plane wall or bared surface to finned surface. About 2.178% of decreased in temperature at fin tip and 48% to 124% of heat transfer rate can be increased by above mentioned extrusion instead of bare surface without extension. Fins with different extrusion are designed with the help of design and analysis software ANSYS®. ANSYS Workbench [ANSYS Multiphysics] is used for thermal analysis which shows that least temperature at the tip is obtained in parallel extrusion and maximum total heat flux is obtain in spline extrusion as compared to other extrusion as discussed above.
