A179 Would Fin Tube L-Shaped AL1060 Fin Carbon Steel Tube Oil Cooler

Overview

An L-shaped fin tube is a type of heat exchanger tube that features L-shaped fins attached to the outside of the tube. These fins are designed to increase the surface area for heat transfer， which in turn improves the efficiency of the heat exchanger.

The L-shaped fins are so named because of their shape， which resembles the letter "L." They are typically made of metal， such as aluminum or copper， and are attached to the tube using a brazing or soldering process. The fins are spaced evenly along the length of the tube， with a certain spacing and height to optimize heat transfer and airflow.

Overall， L-shaped fin tubes are a versatile and efficient heat transfer solution that can be used in a wide range of industrial applications. Their unique design allows for improved heat transfer and increased surface area， making them a popular choice for many heat exchanger systems.

Difference between L， LL， and KL type fin tubes

• The L/LL/KL configuration refers to the shape of the fins on the tube. L-shaped fins have a flat top and a tapered bottom， while LL-shaped fins have a double tapered structure with a groove in the center to improve the bonding strength between the fins and the base tube. KL-shaped fins are similar to L-shaped fins but have a knurled surface to increase the contact area between the fins and the base tube.

• L/LL/KL finned tubes are commonly used in air-cooled heat exchangers， such as radiators， condensers， and evaporators， as well as in industrial process heating and cooling applications.

• L finned tubes， LL (Doulbe L) finned tubes， KL finned tubes (knurled fin tubes) (with aluminum fins)The aluminum fin strip or the copper fin strip is folded into an L shape and spirally wound tightly under the action of tension on the outer surface of the base tube. Tension in the fin strip is wrapped around the tube serves to make the fin foot forcefully on the tube， thus hold the fin firmly in place.
