Fin tubes are tubes that have small fins around the outside surface. These fins act as a filter and a mechanism to transfer heat from the material inside the tube to the outside space or vice versa. Finned tubes are used in applications that require a transfer of heat from a hot fluid to a colder fluid through the tube's wall.
Finned tubes enhance heat transfer efficiency by increasing the surface area for heat exchange. Perfect for applications requiring efficient heat dissipation and compact design.
The finned tube is the core component of the air radiator, and a separate finned tube can also be used as a heat exchanger. There are many varieties of finned tube heat exchangers. In terms of materials, there are carbon steel, copper, aluminum, stainless steel, etc., as well as composite materials, such as steel-aluminum composite, that is, the base tube uses steel and the fins use aluminum; from the fin-type, there are ring fins, longitudinal fins, Spiral fins; fins can be either outside the tube or inside the tube, but there are more outer fins; the process can be integral rolling, welding with the tube, or casting.
Due to their different characteristics, various industries need to choose finned tubes of different types and materials. This article will introduce you to four small knowledge about radiator finned tubes, and take you to understand heat exchanger finned tube.
