Einführung

Some industrial applications for heat exchangers need cost-efficient processes. Thus, it is one of the most popular technologies employed by engineers in high Frequency Welded Fin Tube.

The purpose of this fin tube type is to increase external surface area which allows getting high heat transfer rates. And also it helps you in the greater bonding of fin and base tube.

And as industries push for more efficiency and lower-cost manufacturing, so high frequency welding becomes a common means of producing…

Was ist ein Hochfrequenzgeschweißtes Rippenrohr

Hochfrequenzgeschweißtes Rippenrohr is a type of heat transfer tube in which a fin strip made of metal is welded to the base tube by means of high-frequency electrical current.

The current causes localized heating at the point of contact.

A pressure is applied to create a solid state metallurgical bond.

Consequently, the fin becomes strongly bonded to (or grips) the tube surface.

This structure enhances the thermal and mechanical properties of materials.

Zu den gängigen Materialien gehören:

• Kohlenstoffstahl
• Legierter Stahl
• Edelstahl

So it is a common choice in the heat exchanger systems used in industry.

Working of High Frequency Welded Fin Tubes

Welded fin tubes — Using high frequency welded fin tubes with surface enlargement leads to enhanced thermal performance.

The first scenario involves the presence of either hot or cold fluid flow inside the tube.

Then heat will be transfer over the wall of tube.

After that, the spending joint gets hot very fast.

At the same time, air or gas passes through it over all of its surface.

As a result, heat can escape more readily to the surroundings.

As a result of the fin to base joint being continuously welded, thermal resistance is minimized.

Hence, it largely improves efficiency of the heat exchanger.

Fertigungsprozess

Electrical resistance heating is used for high frequency welding.

The process includes several steps:

4.1 Vorbereitung der Röhrchen

The base tube gets cleaned and straightened up at the manufacturers.

4.2 Zuführung von Lamellenstreifen

Direct feeding of a metal strip to the welding system.

4.3 Hochfrequenzerwärmung

Heat is produced at the point of contact through electric current.

4.4 Druckschweißen

There are rollers that rub the fin against the tube.

4.5 Continuous Welding

They have a spiral structure in the form of fin.

4.6 Kühlung und Inspektion

It is cooled naturally and undergoes strict quality testing.

It means production stays fast and efficient.

High Frequency Welded Fin Tube Structure

High frequency welded fin tube:

5.1 Unterrohr

Carries the working fluid.

5.2 Spiral Fin

Increases heat transfer surface area.

5.3 Schweißzone

Creates a metallurgical interconnection between fin and tube

5.4 Protective Layer

Enhances corrosion resistance if required.

Thus, the structure reinforces both strength and efficiency.
