Air Blast Cooler
What Is an Air Blast Oil Cooler?
It’s a heat exchanger that cools down hot oil by blasting ambient air (using a fan or blower) across a fin-and-tube radiator, where the oil flows inside the tubes.
How It Works:
- Hot oil enters the cooler from the system (engine, hydraulic system, gearbox, etc.).
- The oil flows through a network of tubes surrounded by metal fins.
- A motor-driven fan forces ambient air over the fins.
- Heat from the oil is transferred to the fins and then to the moving air.
Cooled oil exits the cooler and goes back into the system
Components:
- Fan unit: Usually electric or hydraulic powered
- Heat exchanger core: Tubes and fins
- Motor/pump (optional): To circulate oil or power the fan
Thermostatic control (optional): To regulate fan operation based on oil temperature
