What are the benefits of dry-burning electric heating tubes with fins?

There are two types of dry-fire electric heating tubes: finned and unfinned. Unless space is limited, most dry-fire air heating tubes are finned. Some may ask what the benefits of adding fins to dry-fire electric heating tubes are. Today, we'll discuss the advantages of finned dry-fire electric heating tubes.

There are two types of finned electric heating tubes:

1. Wrapped Fin Electric Heating Tubes

These are made by evenly wrapping a 6-7mm wide steel strip around a smooth stainless steel tube using specialized equipment. The thickness of a wrapped fin electric heating tube is equal to the tube diameter + the steel strip x 2.

The gap between the fins of a wrapped fin electric heating tube is 4-5mm.

Wrapped fin electric heating tubes are more cost-effective and are the most popular choice. 2. Square Fin Electric Heating Tubes

Square fin electric heating tubes use rectangular fins strung together on a U-shaped electric heating tube or two straight electric heating tubes. These square fin electric heating tubes have a larger fin area and faster heat dissipation.

Common square fin sizes are 25*50mm and 40*80mm.

Currently, square fin electric heating tubes are still manually threaded, resulting in higher production costs. These are suitable for demanding environments.

Both of these finned electric heating tubes are based on existing plain tube dry-fire electric heating tubes with iron or stainless steel plates added. This increases the heat dissipation area, speeding up heat dissipation and extending the lifespan of the dry-fire electric heating tubes. This is the advantage of finned dry-fire electric heating tubes.
