Dongfeng Xinjiang fan blade 1308010-T5KFJ1Y made in china

Crafted from premium glass fiber-reinforced polyamide (PA66+GF30)—a material renowned for its exceptional mechanical strength and heat resistance—the fan blade offers superior durability for heavy-duty applications. The 30% glass fiber content enhances tensile strength (up to 180MPa) and flexural modulus (up to 5500MPa), enabling the blade to withstand high rotational speeds (maximum 2800 RPM) without deformation or cracking. Additionally, PA66+GF30 exhibits excellent heat resistance, maintaining structural stability even in high-temperature engine compartments (operating temperature range: -40°C to +120°C), outperforming traditional plastic or metal blades in both weight reduction and corrosion resistance

The 1308010-T5KFJ1Y fan blade features an aerodynamically optimized blade profile, developed through computational fluid dynamics (CFD) simulations to maximize airflow while minimizing energy consumption. Each blade has a curved airfoil shape with a precisely calibrated twist angle (15° at the blade root, 8° at the tip) and chord length (gradually reducing from 180mm to 120mm), ensuring uniform airflow distribution across the radiator core. This design delivers a maximum airflow rate of 12,000 m³/h at rated speed, effectively lowering engine coolant temperature by 8-12°C under full load conditions (e.g., climbing steep slopes or hauling heavy loads in high-temperature environments), preventing engine overheating

To ensure long-term reliability in harsh operating environments, the fan blade incorporates multiple durability-enhancing features. The blade hub is reinforced with a metal insert (made of aluminum alloy 6061) that strengthens the connection with the fan clutch, reducing vibration transfer and preventing hub cracking from repeated torque fluctuations. The blade edges are coated with a wear-resistant polyurethane (PU) layer (0.5mm thick), which protects against damage from small debris (e.g., stones, leaves) drawn into the engine compartment. Additionally, the entire blade undergoes a 100-hour high-speed durability test (at 3000 RPM) and a 500,000-cycle vibration test, ensuring it meets Dongfeng Xinjiang’s strict service life requirement of over 400,000 kilometers

Safety is a core priority in the design of the 1308010-T5KFJ1Y fan blade. Each blade undergoes precision dynamic balancing (meeting ISO 1940-1 G2.5 balance grade) to minimize vibration during operation, reducing noise (≤75 dB at 2000 RPM) and preventing premature wear of the fan clutch and water pump bearings. The blade’s root—one of the highest-stress areas—is designed with a filleted transition (radius of 15mm) to distribute stress evenly, eliminating stress concentrations that could lead to fatigue failure. Furthermore, the material’s inherent flame retardancy (meeting UL94 V-0 standard) reduces fire risks in the event of engine oil leaks, ensuring compliance with automotive safety regulations (GB 7258-2024 and ECE R117)
