Aluminum Flat Oval Welded Tube for Radiators is currently one of the most mainstream pipes in automotive radiators, engineering machinery radiators, and household/industrial heat exchangers. Its core characteristics are light weight, fast thermal conductivity, good pressure resistance, easy welding, and high cost.
Core Features of Aluminum Flat Elliptical Welded Pipe (Special for Radiators)
1. Excellent thermal conductivity and high heat dissipation efficiency
The material is mostly 3003/3A21 anti rust aluminum alloy, with high thermal conductivity
The flat elliptical cross-section increases the contact area with the heat dissipation belt/fins
The fluid flows smoothly inside the tube, and the heat transfer efficiency is higher than that of a circular tube
2. Good structural strength, pressure and vibration resistance
Welding forming, uniform pipe wall, good sealing performance
Strong deformation resistance, vibration resistance, and impact resistance of elliptical cross-section
Suitable for vehicles, construction machinery, and other environments with high vibration and harsh working conditions
3. Light weight, significant advantages in lightweighting
Aluminum density is only one-third of copper, significantly reducing the weight of the radiator assembly
Beneficial for vehicle fuel saving, emission reduction, and load capacity enhancement
Easy to install and transport
4. Good welding performance and stable assembly
Smooth surface, high dimensional accuracy, easy to solder with main sheet and fins
High weld strength, good air tightness, and less prone to leakage
Suitable for large-scale production on automated production lines
5. Strong corrosion resistance and long service life
Aluminum alloy itself is resistant to oxidation and corrosion
Can be used for surface passivation/anti-corrosion treatment
Adapt to long-term working conditions such as coolant and high/low temperature circulation
6. Stable molding and high dimensional accuracy
Flat elliptical shape with regular shape and uniform wall thickness
Small tolerances in length, width, and wall thickness
Ensure the consistency of radiator core assembly
7. High cost-effectiveness, suitable for large-scale applications
Compared to copper pipes, it has lower cost and easier availability of materials
Low processing energy consumption and high yield rate
It is the mainstream economical pipe material for modern radiators
