What is the filter screen in front of the car fan?

[OscarAnn]

Engine front filter screen is called the grille, or the middle net. Its main purpose is to ventilate and dissipate heat for the radiator, engine, air conditioning, etc., and to prevent damage to rear components from small stones, insects, and other objects during driving. Expansion: Cars with front-mounted engines have a mesh filter screen in front of the engine, which is the grille. Its main function is air intake and heat dissipation, as the engine requires a large amount of air when operating. Therefore, the grille must ensure sufficient air enters the engine compartment for ventilation and cooling. If the grille is completely hollowed out, it would draw in excessive cold air in winter, causing the engine temperature to drop too low and affecting normal operation. Hence, the grilles we usually see are not completely hollowed out.
