As we know, copper fin tube means both fin and base tube are copper material, which has better optimal thermal conductivity and also corrosion resistant than aluminum fin tube. It's widely used in applications where high heat transfer rates are required.
In terms of classification, copper fin tubes can be categorized into 2 types: extruded type and wound fin tube. Extruded fin tubes are made by extruding fins from the wall of the tube, while wound fin tubes are made by winding copper strips around the base tube.
Tube OD(mm) | Fin tube OD(mm) | FPI | Fin Pitch(mm) |
19/19.05 | 38 | 5-11 | 2.3-5 |
20 | 38 | 5-10 | 2.54-5 |
25/25.4 | 50.8/57 | 5-11 | 2.3-5 |
31.75/31.8 | 63.5 | 5-11 | 2.3-5 |
38/38.1 | 70 | 5-11 | 2.3-5 |
50.8/51 | 82.5/101.6 | 10-11 | 2.3-2.54 |
The material of copper fin tube can be:
Copper-C12200, C12000, C10200
Copper Nickel-C70600
... ...
The advantages of copper finned tubes are numerous. They have a high heat transfer rate, which makes them ideal for applications where efficient heat transfer is critical. They are also durable, corrosion resistant and easy to maintain. Additionally, copper fin tubes have good thermal conductivity, which improves heat transfer efficiency.
Although they have many advantages, copper fin tubes do have some limitations. Copper made fin tubes are expensive compared to other heat exchanger tubes, and they can be more difficult to manufacture due to the added complexity of the fins.
1. Copper Tube with Aluminum Fins
For any fin tubes, the extended aluminum fins are responsible for 65%~70% while the base tube is responsible for the 30%~35%, the combination of copper and aluminum offers the most effective heat transfer at the most efficient cost.
Due to the complicated working environment, some customers would like to choose copper fin for its good heat transfer efficiency and resist corrosion.
Copper is a popular material for embedded finned tubes because it has excellent thermal conductivity, which means it can transfer heat quickly and efficiently. It also has good mechanical properties and can resist to the corrosion.
