Copper Inner Fin Tube for Heat Exchanger

Design Description of Copper Inner Fin Tube:

The high-efficiency and energy-saving inner fin heat exchanger developed by Cangzhou Datang Steel Pipe Co., Ltd. has a heat transfer area of more than 7 times and a heat transfer film coefficient of more than 8 times compared with the same specification of light tubes; the first-class vacuum brazing technology makes the heat exchanger with large heat transfer area, high vibration resistance and high pressure resistance, and can greatly reduce the volume of the heat exchanger, which is particularly suitable for clean and low-viscosity heat exchange media.

Copper Inner Fin Tube

Material: T2 pure copper
Specifications: outer diameter 28, length 296~880, fins 14~24, fin type I-V
Applicable media: 1. Water-steam 2. Water-oil

Inner fin tube is a type of fin tube. Its core feature is to add a fin structure to the inner surface of the heat exchange tube to enhance the heat transfer effect by increasing the heat transfer area of the inner surface. ‌

Structural features of internal finned tubes

Internal finned tubes significantly expand the heat exchange area of the fluid (such as water, steam, etc.) in the tube by processing spiral, longitudinal or rectangular fins on the original tube inner wall. This structure can reduce contact thermal resistance and improve heat exchange efficiency, especially suitable for scenes with large temperature differences or the need to enhance heat exchange in the tube.
