What is the function of the grille?

[KevinDella]

The grille serves functions such as protection, decoration, ventilation, and heat dissipation. The specific roles of the grille are as follows: 1. Protective function: It safeguards the radiator and various components in the engine compartment from impacts by foreign objects. Primarily, it prevents larger stones from entering the engine compartment and damaging internal parts. 2. Decorative function: Without the grille, various pipelines and brackets in the engine compartment would be exposed, affecting the overall appearance of the vehicle. 3. Ventilation, air intake, and heat dissipation: The engine requires air for operation, and the grille ensures that air can enter. However, in winter when temperatures are low, excessive cold air should not be drawn into the engine. Therefore, the design of the grille must ensure sufficient air intake in summer while limiting the amount of cold air entering in winter. This is why it is designed with a hollow pattern. Additionally, it aids in heat dissipation during summer.
