Maintance and Service
Custom Cooling Solutions – We engineer radiators precisely aligned with your unique engine requirements and operational environmental conditions.
Extended Service Life – Durable construction and corrosion resistance contribute to a long operational lifespan with minimal maintenance.
Protective Packaging – Reinforced wooden crates with moisture-proof linings are used for the radiator, preventing copper component corrosion and structural damage during transit.
How We Produce
To ensure optimal heat dissipation under continuous operation, each generator radiator is engineered using specialized CAD simulations. These include thermal flow and structural stress analyses that are precisely tailored to the superior thermal conductivity of copper.
The core fin-and-tube assembly is manufactured with high-precision mechanical expansion, creating a 100% contact joint between louvered copper fins and seamless copper tubes. This process minimizes thermal resistance and increases the heat transfer area by 40% compared to standard designs.
For critical structural integrity, all copper joints are vacuum-brazed with copper-phosphorus filler to withstand thermal cycling, while header-to-tube connections are reinforced with additional argon arc welding to prevent leaks under high vibration.
