Optimized High Frequency Welding Spiral Helix wrapped Fin Tube Heat Exchanger Carbon steel
Product Description of Fin Tube
Unlike a plate fin which has multiple tubes going though a common fin,a spiral finned tubes has its own individual fin"wrapped"onto the outside of the tube.This allows the finned tubes to be arranged in any desired pattern,and any X and Y distance apart.A flat strip of material is helically wound on to a tube,much like threads on ascrew,at the desired fins per inch.The finned tube is then cut to the required coil finned length.Each finned tube is [laced inside the coil casing to create the coil's finned face area and rows deep.
Technical Parameters of Fin Tube
| Spiral Wrapped Fin | |
| Features | Advantages |
| Each tube is individually finned | Increased thermal conductivity |
| Less fin material used | |
| Ability to replace a single damaged tube | |
| More compact fin bundle | |
| Tube face and row centers can vary | |
| Allows coil to better fit with existing case height | |
| Pitch to drain a multi-row for vertical airflow | |
| Tension Bond | Use various fin and tube materials |
| Use various fin and tube thicknesses | |
| Embedded Fin | Maintain fin bond at high temperatures |
| Header | Accommodates header thermal expansion |
| Allows longer header stubs | |
| Technical parameters | The high degree of fin 0-16mm(or outside diameter of fin φ25-φ75); Pitch of fins 2.0-5.0mm; Length of finning tube 0.5~ 14m. |
| Single metal rolling finning tube | Pure aluminum 1060 or aluminum alloy 6063,6061. Outside diameter Shall be less than 40mm |
| Double metal rolling finning tube | Tube-based protection from the outer layer of aluminum tubes,corrosion-resistant,Tube-based can be made of carbon steel pipe,in addition to,stainless steel tube and copper tube can also be used, as well as titanium alloy tube |
| Package | The aluminum finned tubes are well packed in plastic film in the inner and steel fram in the outer |
Features of Fin Tube
1. The equipment body can be designed into many modules to ensure the long term and stable running.
2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage.
3. Improve the heat transfer efficiency.
4. Structure arrangement: In line or staggered arrangement.
