[0002] At present, the fan wind protection devices used in automobiles are mainly divided into two types: one is the wind protection device for the open fan (larger noise), and the wind protection ring is fixed on the engine, and the wind protection ring and the wind protection cover are connected by a wind protection device. The soft cover connection allows the gap between the outer circle of the fan and the windshield to be made very small, effectively reducing the secondary backflow and improving the efficiency of the fan; the other is for the ring fan (with better low noise performance) Generally, a U-shaped windshield is used to assemble it. Considering the beating of the fan, the gap between the fan and the windshield is large, so the secondary return air volume is large, which affects the air intake efficiency of the fan.

Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0021] Such as figure 1 and 5 shown, as attached figure 2 As shown, the device includes six parts, namely: wind shield 1, clamp 2, wind shield soft cover 3, wind shield 4, annular fan 5 and wind shield support 6. One end of three wind protection ring supports is fixed near the front face of engine 7 cylinder block, and is used for fixing the wind protection ring. The wind protection ring wraps the annular fan. The radial gap between the wind protection ring and the outer wall of the annular fan is preferably greater than or equal to 6mm and less than or equal to 8mm. The gap greater than or equal to 6mm prevents the engine from beating and machining errors that cause the fan to touch the wind protection ring during operation. . The windshield is fixed on the radiator 8, a...

The invention provides a vehicle fan wind protection hood device. The vehicle fan wind protection hood device comprises a wind protection hood, a clamp, a wind protection soft hood, a wind protectionring, an annular fan and wind protection ring supports. The annular fan is adopted as the fan of the device, and the wind protection ring is designed outside the annular fan and fixed through the three wind protection ring supports. One ends of the wind protection ring supports are fixed to an engine, and the other ends of the wind protection ring supports fix the wind protection ring. The wind protection soft hood covers the outside of the wind protection ring and the wind protection hood, and fixing is conducted through the clamp. The wind protection ring is designed outside the annular fanso that a gap between the fan and a wind protection device can be effectively reduced, secondary circulation of airflow is reduced, and the fan efficiency is improved; and meanwhile, due to adoption of the annular fan, the noise of a whole vehicle can be effectively lowered.
