Background

At present, with increasingly strict requirements of engine emission regulations, under the condition that heat transferred to a cooling system by an engine and other components is unchanged or increased, the cooling capacity of a whole vehicle cooling system is required to be improved under the condition that the space size is unchanged; that is, it is necessary to increase the cooling air volume, increase the fan efficiency, and further enhance the cooling capacity without increasing the fan power consumption and the fan noise. In order to improve the efficiency of the fan, the structure of the fan and the fan wind-protecting ring and the cooperation between the fan and the fan wind-protecting ring are very important.

The cooling system has used a large number of ring fans, which have the characteristics of low noise, high strength, etc. compared with the common fans. In the matching of the annular fan and the fan air protecting ring, the fan air protecting ring adopts a labyrinth type and is matched with the annular fan to have the highest air quantity and the lowest noise. When the outer ring of the annular fan rotates between the inner ring and the outer ring of the labyrinth type wind protection ring, the turbulent flow loss caused by the edges of the blades when the traditional fan rotates is avoided, so that the air quantity of the fan is increased on the premise of not increasing the rotating speed and the power consumption of the fan, and the noise caused by air turbulent flow at the edges of the blades when the fan rotates is reduced. However, because the fan protects the solar or lunar halo and installs on the radiator, and the fan is installed on the engine, and amplitude, direction and vibration frequency between them are all inconsistent, and the clearance is less between ring fan and the protection solar or lunar halo, can make ring fan and protect scraping each other between the solar or lunar halo, lead to wearing and tearing or destruction, reduce life, cause very big influence to the cooling effect of whole car.
