Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and in particular to a flow guide structure for increasing the air intake volume of a small opening grille of a vehicle. Background Art

[0002] For the front face with small opening shape, there is only a lower grille on the front bumper, and the air volume passing through the lower grille can only blow directly to the lower section of the heat exchanger. To increase the air volume of the radiator, it is necessary to guide the air flow upward through the upper section of the heat exchanger as much as possible. In the prior art, the traditional large opening shape usually has an upper grille, and the external air flow can blow directly to the upper section of the heat exchanger through the grille. The air intake volume can easily meet the heat dissipation requirements and there is no such problem; for the small opening shape, the air guide cover around the front end of the heat exchanger is usually arranged behind the anti-collision beam, resulting in a very small gap between the air guide cover and the heat exchanger core, which increases the resistance to the upward flow of the air volume of the lower grille, which is extremely unfavorable to increase the air volume of the small opening shape. If the air guide cover is arranged in front of the anti-collision beam, it will bring new problems such as driving insurance and collision safety. Utility Model Content
