Fin Tubes  Manufacturers, Traders, Suppliers

Fin tubes, also known as finned tubes, are a type of heat exchanger component designed to enhance the heat transfer efficiency between fluids or between a fluid and the surrounding environment. The finned tube is divided into two parts, the base tube and the steel strip wrapped around the surface of the base tube, also known as the fins. These fins significantly increase the surface area available for heat transfer, improving the overall performance of the heat exchanger.
The primary purpose of fin tubes is to augment heat transfer by increasing the effective surface area in contact with the fluid. This is particularly useful in applications where space or weight constraints limit the size of the heat exchanger.

Types: Extruded, spiral wound, L, LL, KL, G, elliptical/oval, serrated, longitudinal, etc.
Material: Fin tubes are typically made from materials with good thermal conductivity, such as metals like aluminum, copper, or alloys.
Tube Diameter and Thickness: The diameter and thickness of the base tube are crucial factors influencing the overall mechanical strength and heat transfer characteristics.
Tube Length: 11 meters maximum
Fin Height and Thickness: The dimensions of the fins, including height and thickness, impact the surface area available for heat transfer. These dimensions are determined based on the specific heat exchanger requirements.
Fin Density: Fin density refers to the number of fins per unit length of the tube. It affects the overall heat transfer performance and pressure drop in the system.
Fin Pitch: Fin pitch is the distance between adjacent fins. It plays a role in determining the airflow or fluid flow patterns and influences the heat transfer efficiency.

Air Cooled Heat Exchangers (ACHE): Commonly used in industrial settings where water availability is limited, and air is used for cooling.
Refrigeration and Air Conditioning: Fin tubes are employed in evaporators and condensers to enhance the efficiency of heat exchange processes.
Process Heat Exchangers: Used in various industries for heating or cooling processes, including chemical and petrochemical applications.

Air Heat Exchangers of Lamellae or Finned Tube Design
Temperature exchange for gasses
With air heat exchangers, there is an exchange of temperature between a gas (normally air) and a liquid. Very often air heat exxhangers are also used as waste-gas heat exchangers or smoke-gas heat exchangers for heat recovery.
Lamellae or finned tube
In order to obtain a rather large exchange surface between air and medium (liquid) inside of the heat exchanger thin plates defined as lamellae or finned tube are applied to the pipe system. This heat exchanger type is mainly used in the processing and especially in the air conditioning technology.
