Description

Its main function is to adjust the air intake volume by instantly controlling the size of the grille opening according to the cooling system's heat dissipation needs when the car is driving, thereby ensuring the thermal balance of the car's engine compartment. When the car engine needs to heat up quickly to reach the operating temperature, the active air intake grille will close to reduce the circulation of outside air and the air in the engine compartment, thereby achieving the effect of rapid heating; when the car is driving normally, the active air intake grille will open to meet the air circulation between the outside air and the engine compartment, thereby achieving the purpose of cabin heat dissipation.
