Dongfeng GX fan shroud 1309011-H19D0 for sale

As a critical component of the engine cooling system, this fan shroud is designed to maximize airflow concentration and heat transfer efficiency. Its aerodynamic structure features a tapered inner wall (15° draft angle) that funnels air from the engine fan directly through the radiator core, reducing airflow dispersion by up to 40% compared to non-shrouded setups. The shroud’s fan opening is precisely sized to match the engine fan (clearance: 10mm between fan blade tip and shroud), minimizing air recirculation (where hot air from the radiator is pulled back into the fan) and ensuring a steady airflow rate of ≥2500 m³/h at maximum fan speed. This optimized airflow lowers engine coolant temperature by 5-8°C under high-load conditions (e.g., uphill hauling, high ambient temperatures), preventing engine overheating and maintaining optimal performance

The fan shroud is constructed from glass fiber-reinforced PP (polypropylene) plastic (20% glass fiber content), a material chosen for its exceptional balance of strength, lightweight properties, and heat resistance. It achieves a flexural strength of ≥50 MPa and an impact strength of ≥8 kJ/m² (at 23°C), enabling it to withstand minor impacts from road debris or engine bay components without cracking. The material also maintains structural integrity across a wide temperature range of -40°C to +120°C—critical for withstanding engine bay heat (up to 100°C) and cold winter conditions. Additionally, the shroud’s thickened edge (3mm thickness) and reinforced mounting points enhance durability, ensuring it resists vibration-induced wear during long-term operation (tested to 1 million cycles of vibration at 10-2000Hz)

The shroud features an integrated, user-friendly design that combines cooling performance with practical maintenance needs. It includes a removable inspection panel (secured by 4 quick-release clips) on the side, allowing technicians to access the radiator core for cleaning or fan inspection without removing the entire shroud—reducing maintenance time by 50%. The top edge of the shroud is equipped with a rubber gasket (HNBR material) that forms a tight seal with the engine hood, preventing hot air from the engine bay from entering the radiator intake. Additionally, the shroud incorporates pre-marked cutouts for coolant hoses and sensor wiring (compatible with the GX platform’s temperature sensors and fan control modules), ensuring no interference with other engine components and simplifying installation

This fan shroud meets strict domestic and international standards for automotive cooling system components. It complies with GB/T 28933 (China National Standard for Automotive Plastic Parts for Cooling Systems), ISO 10067 (International Standard for Automotive Radiator Shrouds), and Dongfeng’s internal Q/DF 031-2024 specification for engine cooling shrouds. Each unit undergoes rigorous factory testing, including: a heat aging test (1000 hours at 120°C), a cold impact test (-40°C for 24 hours followed by impact testing), an airflow efficiency test (verifying ≥2500 m³/h airflow), and a dimensional accuracy inspection using 3D scanning. These certifications ensure the shroud’s reliability, compatibility, and compliance with global emission and safety regulations, making it suitable for Dongfeng GX trucks operating in diverse climates and regions
