Mini Fin Tubes

Fin Tube Products, Inc. is a leading miniature custom manufacturing company that develops micro fins or Mini Fin Tubing. They are available in sizes descending from 1/4″ to a diameter as small as .015″. The fin micro tubes are used in various applications in different industries. With our in-house capabilities, we can meet our customers’ specific requirements and preferences.

The fin-micro tube is helically coiled and attached to the tube by a soldered or FINBRAZE® fin. Additionally, we collaborate with engineers to create a prototype design that will go through pilot tests.

What is a Mini-Fin Tubing?

Mini-Fin Tubing is miniature tubing typically used for small heat exchangers, air-cooled condensers, or evaporators. They are used mainly in low-temperature cryogenic or biomedical applications. For instance, it’s for cryogenic use for coiled heat exchangers supporting a Joule-Thomson port (J-T port).

Mini fin tubes offer increased surface area compared to their large counterparts and reduce the overall size of the heat exchanger. It’s achieved by combining small fins and tubes with a unique process called micro-finning.

Benefits of Using Mini Fin Tubes

The mini-fin tubes we manufacture have superior reliability and performance, enhancing their overall application. Some of its advantages include the following:

• Increases heat transfer rate
• Lowers the cost of miniature components
• Reduces the size and weight of the miniature device

Mini-fin tubes are manufactured specifically for various purposes requiring their distinctive miniature sizes and fin micro tubes.

Materials for Mini Fin Tubes

Mini fin tubes are primarily available in three materials/metals. These are:

• Copper: Copper is a metal that is highly efficient in heat transfer. Copper is used in manufacturing miniature finned tubes due to its superior thermal conductivity and durability.
• Copper Nickel: Copper Nickel is also commonly used in mini fin tubes due to its superior corrosion resistance and high ductility properties.
• Stainless: Small steel miniature finned tubes are an excellent choice for applications requiring a higher working temperature.

Common Industries Served

Despite their small size, micro fin tubings are used in different industries. These industries are as follows:
