Finned tubes are heat exchanger tubes with extended surfaces to increase the effective heat transfer area. This makes them ideal for applications where high heat transfer rates are required, such as in power plants and refrigeration systems.
The extended surface can be in the form of fins, which are metal plates that are welded, brazed, or bonded to the tube. In some cases, the finned tubes may also have an inner groove or an outer groove to increase its surface area further.
Fin tubes are made from a variety of materials, including copper, aluminum, and stainless steel. They are available in a range of sizes and shapes and can be customized to meet the specific needs of each application.
