Introduction
An Air Blast Oil Cooler (ABOC) is a type of air-cooled heat exchanger designed to remove heat from lubricating oil, hydraulic oil, gear oil, and compressor oil using atmospheric air. Industries prefer this cooling system because it eliminates water usage, prevents contamination, and reduces operating cost.
Choosing the right air blast oil cooler manufacturer is critical because cooling performance directly affects machine life, bearing protection, and energy efficiency.
What is an Air Blast Oil Cooler?
An Air Blast Oil Cooler uses a motor-driven fan to force air across finned tubes carrying hot oil. Heat transfers from oil → tube → fins → air.
It is commonly installed in:
- Hydraulic power packs
- Gearboxes
- Turbines
- Compressors
- Diesel engines
- Marine equipment
Working Principle
The cooler works on forced convection heat transfer.
Operation Steps
- Hot oil enters the inlet header
- Oil flows through finned tubes
- Fan blows ambient air over fins
- Heat dissipates into atmosphere
- Cooled oil returns to equipment
Heat Removed=U×A×ΔT
Large fin surface area improves cooling efficiency even with low-conductivity air.
