Efficient heat transfer: the inside of the finned tube is filled with a working fluid, usually a liquid metal or organic substance with a low boiling point. When one end of the finned tube is heated by a heat source, the working fluid evaporates into a gas, which is then conducted inside the tube to the cold end, where it condenses back into a liquid to release heat. This is a very efficient way of heat transfer.

Uniform Heat Distribution: Finned tubes efficiently transfer heat from the heat source to the larger surface area of the radiator, allowing for uniform heat distribution. This helps prevent localized overheating and equipment damage.

Lightweight and Compact: Finned tubes are typically lightweight and compact in design, fitting into a variety of equipment space constraints. They require no external power or mechanical components, so they provide efficient passively cooling.

High Reliability: Finned tubes are highly reliable because they have no moving parts inside. This makes them stable in a wide range of environments and operating conditions.

Finned tubes are widely used in electronic equipment, computers, LED lighting, solar thermal power generation, etc. to meet the requirements for effective and reliable heat dissipation.
