Component Specifications

Definition
The radiator core is the primary heat transfer element within a radiator assembly, consisting of tubes and fins that facilitate efficient thermal exchange between hot coolant and ambient air. It functions as a cross-flow heat exchanger where coolant flows through tubes while air passes over finned surfaces, dissipating heat through conduction and convection to maintain optimal operating temperatures in machinery.
Working Principle
Operates on heat transfer principles: conduction through tube walls and fins, and convection as air flows across fin surfaces. Hot coolant transfers thermal energy to tube walls, which conduct heat to fins where forced air convection carries heat away, following the equation Q = U × A × ΔT (heat transfer rate = overall coefficient × area × temperature difference).
Materials
Typically aluminum alloys (3003, 5052) for lightweight corrosion resistance, or copper-brass combinations for high thermal conductivity. Fins: aluminum (0.1-0.3mm thickness). Tubes: aluminum (0.3-0.5mm wall) or copper (0.2-0.4mm). Headers: aluminum casting or plastic composites.
Technical Parameters
  • Fin Pitch 1.5-3.0mm
  • Flow Rate 10-100 L/min
  • Tube Pitch 8-12mm
  • Fin Density 8-16 fins per inch
  • Tube Thickness 0.3-0.5mm
  • Core Dimensions Varies by application (typical: 300-800mm width × 200-600mm height × 16-50mm depth)
  • Pressure Rating 100-300 kPa
  • Thermal Capacity 5-50 kW depending on size
Standards
ISO 16369, DIN 30676, SAE J1394

Frequently Asked Questions

What is the difference between a radiator core and a complete radiator assembly?

The radiator core is the central heat exchange component containing tubes and fins, while the complete assembly includes additional components like tanks, headers, mounting brackets, and connections.

How do I determine if a radiator core needs replacement?

Signs include visible corrosion or damage to fins/tubes, reduced cooling efficiency (overheating), coolant leaks at core joints, or pressure test failures indicating structural weakness.

Can aluminum and copper radiator cores be used interchangeably?

Not directly - they have different thermal properties, expansion rates, and connection methods. Compatibility depends on system design, coolant type, and connection interfaces.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
