Cummins Turbocharger Heat Shield 3535611 For QSK60

The outer layer is stamped with Inconel 718 nickel-based alloy (with a temperature resistance of 1100°C), the middle sandwich is ceramic fibre aerogel (with a thermal conductivity ≤ 0.018W/m-K), and the inner layer is compounded with an aluminium foil reflective film (with a reflectivity ≥ 95%). This improves the overall thermal resistance by 8 times compared with the traditional single-layer steel cover.

With edge integrated labyrinth cooling ducts and a nano thermal insulation coating (with a thickness of 100μm), the surface temperature is reduced by 120°C compared with competing products, and the ambient temperature of the machine room is reduced by 15°C (measured data).

The bracket adopts titanium alloy memory metal (Ti-6Al-4V), which compensates for thermal expansion displacement through the shape memory effect (with a compensation amount of 0.3mm/100°C), and the preloading force of bolts attenuates by ≤5% after a 20-500Hz random vibration test.

With a surface aluminium-silicon coating (with a thickness of 50μm), it has passed the ASTM B117 salt spray test for 4000 hours without corrosion, making it suitable for environments such as marine engineering and chemical tail gas where the Cl- concentration is > 800ppm.

• Generator sets: Adapted to QSK60 - G3 diesel generator sets, it reduces the ambient temperature of the turbine compartment from 180°C to 65°C and extends the life of peripheral sensors by 3 times.

• Mining Machinery: Used in Caterpillar 994F mining trucks, the wiring harness aging rate is reduced by 70% under a dust concentration of 500mg/m³.

• Marine power: Matched with the QSK60 - M marine main engine, it has passed DNV-GL fire certification (A60 standard), and the cabin fire risk level is reduced to Class 0.

• Energy-saving revolution: The active heat dissipation design reduces the cooling system load, improving the comprehensive fuel efficiency by 0.9%. This results in an average annual fuel cost saving of about 45,000 yuan per unit (calculated based on 8,000 hours/year).

• Intelligent thermal sensing: An optional embedded thermocouple (type K, 0-1200°C) is available. Data is directly transmitted to the Cummins Vision+ system, enabling real-time generation of a heat flow density cloud map. The accuracy rate of the warning code SPN 3712-15 (heat radiation over limit) is ≥ 99.7%.
