Description

Technical Field

[0001] The utility model relates to the technical field of rectifier nets, in particular to a rectifier net for an AGS leakage test device. Background Art

[0002] AGS is the active air intake grille of the car. The active air intake grille is part of the vehicle's thermal management system. It is located at the head of the vehicle and integrated with the center grille on the front bumper. When the vehicle is cold-started, in order to quickly heat up the engine, the front air intake grille will be closed to allow the vehicle engine to reach the operating temperature as soon as possible. When the vehicle temperature is too high, the front air intake grille will actively open to allow the engine to dissipate heat as quickly as possible. When the vehicle is driving at high speed, the air intake grille will actively close to reduce the vehicle's wind resistance and improve fuel economy. In order to test the leakage of AGS, an AGS leakage test device is required for testing. In order to better test it, a rectifier network for an AGS leakage test device is proposed.

[0003] For example, an AGS leakage test device disclosed in the authorization announcement number CN117470451B includes an air duct, one end of which is connected to an auxiliary fan, and the other end of which is connected to a test piece connection structure. The air duct includes an air duct top plate, and a splicing plate, which is installed on the air duct top plate and is located between the auxiliary fan and the rectifier network group;

[0004] Although it realizes spraying water into the air duct through the spray pipe group, the wind blown out by the auxiliary fan is mixed with the spray water and flows toward the rectifier network group, so as to simulate the situation that the AGS contacts the air mixed with rainwater in rainy weather. When the wind speed of the auxiliary fan decreases, the spray water speed of the pipeline component is increased, so that when simulating the rainy environment, the air mixed with water at low wind speed can also contact the AGS, thereby realizing the test of its leakage amount. At high wind speed, the spray water speed of the pipeline component is appropriately reduced to avoid the problem that the AGS is sprayed with a large amount, which causes the test environment to be unrealistic and thus affects the test results.

[0005] However, the problem that the existing rectifier network is not conducive to convenient linkage vertical adjustment of the rectifier angle and horizontal adjustment of the rectifier angle during use is not solved, and it is not conducive to rapid horizontal and vertical rectifier adjustment of the air, which affects the convenience and flexibility of the rectifier.
