Does Radiator Matters for Diesel Generator ？
1. Key Functions of Radiators
- Heat Dissipation(Cooling the engine)
- Circulates coolant to transfer engine heat to the air, maintaining optimal operating temperature (80-95°C).
- Freeze & Boil Protection
- In some freezing cold environment places in winter season, some places temperature are very low, some are reach to -40°C . normally under this condition. need to add coolant in radiator .coolant contains antifreeze agents, functioning stably between -40°C to 120°C to prevent thermal damage and protect genset running .
- Corrosion & Scale Prevention
- Inhibits rust and mineral deposits in the cooling system, extending engine lifespan.
1. How to Choose the Right Radiator?
- Cooling Efficiency: Match heat dissipation capacity with generator power (kW)
- Compatibility: Ensure precise fit with detail engine models
- Environmental Adaptability: Choose a 50 °C type radiator in tropical areas and other area normally choose 40 °C type radiator is okay.
- Cooling Fins’ Material : Copper or Aluminum
2. OEM vs Third-Party Radiators
| Factor | OEM Radiator | Third-Party Radiator |
|---|---|---|
| Compatibility | 100% engine fit | Risk of manual adjustments |
| Warranty | 1-year global coverage | 1-year local warranty |
| Cost | Higher (+30%~50%) | Cheaper |
3. Copper vs Aluminum Radiators
- Copper Cooling fins:
✅ High thermal conductivity , 15%~20% efficiency gain
✅ Long lifespan in harsh conditions (mining/marine)
❌ Heavyweight , higher cost - Aluminum Cooling fins:
✅ Lightweight (-35%), cost-effective for mass production
✅ Easy customization
❌ Requires anti-oxidation treatment, cheap than copper one
