Tube Fin Type Tube-Fin Cooler L-Type Wound Finned Tube

L-type wound finned tube: aluminum fin or copper fin is folded into an L shape and continuously

spirally wound on the outer surface of the base tube under the action of tension.

High operating temperature: 150 °.

Ll type wound finned tube: on the basis of L type, the fin root completely covers the outer surface

of the base tube; To some extent, this fin type ensures better corrosion resistance.

High operating temperature: 170 °

KL type wound finned tube: before the fins are continuously wound on the surface of the steel pipe,

the outer surface of the base tube needs to go through the knurling procedure; After the fin is wound,

the root of the fin attached to the steel pipe will also be knurled to strengthen the combination of the steel pipe and the fin.

For this reason, this fin type ensures better heat transfer characteristics than under the fins of L and LL.

High operating temperature: 250 °.

Advantages:

the manufacturing method of wound finned tube can ensure ideal fin processing on a

very thin-walled tube when using high-value alloy (titanium tube, stainless steel tube, copper tube, etc.).

The pipe can withstand temperatures up to 150 ° without the risk of atmospheric corrosion or thermal stress.

Product features:

1. As a new type of enhanced heat transfer element, the main advantage of needle tube is to reduce the

thermal resistance and greatly improve the heat transfer coefficient.

2. Because the needle rib of needle tube is a cantilever structure, the needle rib vibrates under the impact of air flow,

making it difficult for soot to accumulate; Coupled with the strong turbulent scouring of flue gas, the needle tube

heat exchange element has strong self ash removal ability.

3. The needle tube has compact structure, low metal consumption per unit heat exchange, small volume and

small floor area. Square and hexagonal needle tube heat exchange elements have the advantages of good

heat transfer performance, less ash accumulation and small volume. They have broad application prospects

in heat exchange and energy saving projects.
