Guide structure for passenger vehicle head

Abstract

The invention discloses a guide structure for a passenger vehicle head. An upper grid (2) and a lower grid (3) are arranged on a front bumper (1), the upper grid (2) is arranged above the lower grid (3), and a left guide plate (4) and a right guide plate (5) are further arranged in the front bumper (1). The left guide plate (4) is positioned at the left ends of the upper grid (2) and the lower grid (3), and the right guide plate (5) is positioned at the right ends of the upper grid (2) and the lower grid (3). An upper guide plate (6) is arranged behind the upper grid (2) transversely, and a lower guide plate (7) is arranged behind the lower grid (3) transversely. The upper guide plate (6), the lower guide plate (7), the upper grid (2) and the lower grid (3) define a square. By means of the guide structure, air entering the upper and lower grids can be guided to flow to a condenser and a radiator, and accordingly, not only the radiation efficiency of the condenser and the radiator is guaranteed, but also air eddies are effectively prevented, and the utilization ratio of motor output power is improved greatly.

Description

Technical field [0001] The invention belongs to the field of automobile technology, and specifically relates to a gas diversion structure of the front of a passenger car. Background technique [0002] The front bumper of the passenger car is provided with upper and lower grilles. When the passenger car is running, air enters the engine compartment through the upper and lower grilles to cool the condenser and radiator by air cooling. The shortcomings of the existing structure are: [0003] 1) The transverse ribs of the upper grille are generally inclined upward due to the requirements of the processing technology, so when the passenger car is driving, the intake air of the upper grille flows from low to high, so that a large part of the airflow will flow from the condenser The part of the airflow does not pass through the condenser and the radiator, which will affect the heat dissipation effect, especially when the upper grille is small, the position is higher, or the vehicle speed...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to the needs of processing technology, the horizontal ribs of the upper grille are generally inclined upwards, so when the passenger car is driving, the intake air of the upper grille flows from low to high, so that a large part of the airflow will flow from the condenser This part of the air flow does not pass through the condenser and radiator, which will affect the heat dissipation effect, especially when the upper grille is small, the position is higher, or the vehicle speed is faster.

[0004] 2) A large part of the airflow entering the upper grille directly rushes to the engine compartment plate, and a large part of the airflow entering the lower grille directly rushes to the lower guard plate of the engine, which will generate vortex in the engine compartment. The air-cooling effect of the condenser and radiator, on the other hand, increases the resistance of the passenger car and reduces the utilization rate of the engine output power
