Intercooler Manufacturer in India

What is an Intercooler?

An intercooler is a heat exchanger that cools compressed intake air (charge air) in turbocharged/supercharged engines, improving combustion efficiency and power

output. It reduces intake air temperature by 50-100°C, increasing air density for better engine performance.

How an Intercooler Works

1. Hot Compressed Air (80-200°C) enters from the turbocharger/supercharger.
2. Cooling Medium (ambient air or liquid coolant) absorbs heat.
3. Cooled Air (30-60°C) flows into the engine, increasing oxygen density.
4. Result:
   1. More efficient combustion → 10-30% power boost
   1. Reduced risk of engine knocking

Types of Intercoolers

1. Air-to-Air Intercooler

• Design:
  • Finned tubes exposed to ambient airflow (front-mounted in vehicles).
• Pros:
  • Simple, lightweight, no coolant required.
• Cons:
  • Less effective in slow-moving/hot environments.
• Applications:
  • Most turbocharged cars (e.g., Subaru WRX, diesel trucks).

2. Air-to-Water Intercooler (Liquid-Cooled)

• Design:
  • Uses coolant (water/glycol) to cool charge air.
• Pros:
  • More compact, better for confined spaces.

• Consistent cooling (less affected by ambient temps).
• Cons:
  • Heavier, requires a separate coolant circuit.
• Applications:
  • High-performance cars (e.g., Audi RS models), marine engines.

3. Twin-Charge Intercooler

• Design:
  • Combines air-to-air and air-to-water systems.
• Use Case:
  • Extreme performance builds (e.g., drag racing).

Key Benefits

 Increased Power – Denser air = more fuel can be burned.
 Better Fuel Efficiency – Optimized combustion reduces waste.
 Engine Longevity – Prevents overheating/detonation.
 Lower Emissions – Cleaner burn reduces CO and NOx.

Performance Factors

Factor	Impact
Core Size	Larger = better cooling but higher pressure drop
Fin Density	More fins = better heat transfer but clogs easier
Material	Aluminum (lightweight, good conductivity)

Mounting Location

Front-mount (air-to-air) vs. top-mount (short piping)

Common Applications

• Automotive: Turbocharged cars, diesel trucks.
• Marine: High-performance boat engines.
• Aircraft: Turbocharged piston engines.
• Industrial: Turbocharged generators.

Intercooler vs. Aftercooler
