FL series oil cooler is mainly used for walking machinery (excavators, loaders, forklifts, cranes, combine harvesters, asphalt pavers, road construction machinery, engineering vehicles, etc.) and for hydraulic system, lubrication system, cooling system, etc. to cool the working medium to the required temperature.

1.Using air as cooling medium has the following advantages:
The structure is simple and no thermal resistance.
Model meaning: example: fl20 refers to FL air cooler, 20 refers to heat exchange area (inch).

2.Performance parameters of cooler
Traditional coefficient: ≤ 55W / m2 ℃
Design temperature: 100 ℃
Working pressure: 1.6Mpa
Pressure drop: 0.1MPa

3.Formation of manufacturing process
Integral copper rolled spiral finned tube;
Whole aluminum rolling spiral tube;
The fin can be aluminum, iron and copper according to the need;
Stamping forming of smooth tube and welding of fin.
