Copper-aluminum composite finned tube

Finned Tube Overview
Finned tubes are designed to enhance heat exchange efficiency by adding fins to the surface of the heat exchange tubes, thereby increasing their external (or internal) surface area. This design achieves higher heat exchange efficiency. As a heat exchange element, finned tubes operate under high-temperature smoke conditions for extended periods, such as in boiler heat exchangers where the environment is severe—high temperature, high pressure, and corrosive atmosphere. This necessitates finned tubes to have high performance specifications.
1. Corrosion resistance
2. Abrasion resistance
3. Low thermal contact resistance
4. High Stability
5. Dust-Resistant Ability

Finned Tube Classification
Finned tubes come in a variety of types and new varieties are continually emerging. Finned tubes can generally be categorized into the following application scenarios:
Categorized by processing technology: 1. Strip tube (sleeve tube); 2. Tension-wound finned tube; 3. Inserted fin tube; 4. Integral rolled finned tube; 5. Cast finned tube; 6. Welded finned tube, which includes: High-frequency welded finned tube, submerged arc welded finned tube, etc.
Categorized by fin shape: 1. Square, rectangular, and circular fin tubes; 2. Spiral fin tubes; 3. Wavy fin tubes; 4. Toothed fin tubes; 5. Needle fin tubes; 6. Vertical fin tubes; 7. Solid plate fin tubes (plate fins) and more.
Categorized by material: 1. Copper, Aluminum, Copper/Aluminum finned tubes; 2. Carbon steel, Stainless steel, Carbon steel/Stainless steel finned tubes; 3. Cast iron (cast steel) finned tubes, etc.
Categorized by application: Air conditioning finned tubes; Air-cooling finned tubes; Boiler finned tubes for water walls, economizers, and air preheaters; Finned tubes for various kilns and industrial furnaces for waste heat recovery; Other special-purpose finned tubes, etc.

Finned tube advantages
1. High Efficiency and Energy Saving: Its heat exchange coefficient ranges from 3000 to 4500 kcal/m²·°C·h, which is 3 to 5 times more efficient than shell-and-tube heat exchangers.
2. Compact Structure: Plate heat exchangers have tightly arranged plates, which occupy less floor area and space compared to other types of heat exchangers. A plate heat exchanger with the same heat exchange capacity as a shell and tube heat exchanger requires only 1/5 of the area.
3. Easy to clean and assemble: The plate heat exchanger clamps the plate packs together with clamping bolts, making it easy to disassemble and clean at any time. Additionally, due to the smooth plate surface and high turbulence, scaling is unlikely.
4. Long Service Life: Plate heat exchangers are made of stainless steel or titanium alloy plates, capable of withstanding various corrosive media. Gaskets are replaceable, and it is easy to disassemble and inspect.
5. Versatile: Plate heat exchanger plates are individual components, allowing for adjustments in flow as required, with various configurations; suitable for different process demands.
6. Non-leaking design, with a sealed groove incorporating a liquid drainage channel in the plate heat exchanger. Different media do not intermix, and in case of leakage, the medium always discharges outward.
