Introduction of Annular Fan Blade 202V06600-7025

Product Features
Good heat dissipation perforce: As an important part of the engine cooling system, its special annular design and reasonable blade angle and spacing can effectively drive a large amount of air flow when the engine is running, quickly dissipate the heat generated by the engine, and ensure that the engine works within a suitable temperature range, thereby ensuring the perforce and reliability of the engine and extending the service life of the engine.
High matching degree with the engine: This fan blade is specially designed and developed for the Sinotruk MC07 engine, and is highly matched with the overall structure and perforce characteristics of the engine. Its installation size and connection method are precisely matched with other parts of the engine, and can be perfectly integrated into the engine's cooling system to achieve efficient collaborative work.
Reliable and durable quality: It usually adopts high-quality materials and advanced ufacturing processes, has high strength and rigidity, can withstand the influence of factors such as high temperature, high-speed airflow and vibration generated when the engine is running, and is not prone to deformation, damage and other problems, ensuring the long-term and stable use of the fan blade.

Working principle of annular fan blade 202V06600-7025

The silicone oil fan clutch is a key component of the fan blade. When the engine temperature is low, the silicone oil in the silicone oil fan clutch is in a low temperature state and has low viscosity. At this time, the connection between the fan blade and the engine is relatively loose, and the fan blade has a low speed, thereby reducing the power consumption of the engine.
When the engine temperature rises, the silicone oil is affected by the high temperature, and the viscosity increases, making the connection between the fan blade and the engine tighter. The speed of the fan blade increases accordingly, increasing the air flow, improving the heat dissipation effect, and effectively controlling the engine temperature.
