What is the mesh in front of a car called?

The mesh-like component at the front of a car is called the car grille, radiator grille, or radiator cover. The metal grille (Grille), also known as the car front face, radiator grille, or radiator cover, primarily serves to allow air intake for the radiator, engine, and air conditioning system. It also protects internal components from damage caused by foreign objects during driving and enhances the car's aesthetic appeal. As the window for supplying air to the engine, the intake grille is usually located behind the car grille and directly in front of the engine compartment. Its main functions are heat dissipation and engine air intake. Generally, the car's "front gate" remains open, allowing outside air to freely enter. This means that during cold driving, the already low-temperature radiator is further cooled by the outside air, causing the water temperature to rise very slowly. As a result, the engine takes longer to reach its optimal operating state. Many car models experience slow and significantly reduced heating effects in winter due to this. The car's heating system does not rely on a compressor or electric auxiliary heating, with only a very few electric vehicles using the compressor's heat pump system for auxiliary heating. In fuel-powered cars, the warm air comes from the "residual heat" of the engine operation. This heat warms the antifreeze coolant, and when the heating is turned on, a valve connected to the water cooling system opens, allowing the high-temperature antifreeze to flow into the heater core and heat up. The blower then blows cold air over the high-temperature heater core, heating the air through the principle of heat absorption by lower-temperature objects. This is the principle of heating. If the temperature is too low and the vehicle is moving, the cold air will excessively absorb heat from the engine's radiator, preventing the internal antifreeze coolant from reaching a high temperature. This description might seem exaggerated, but it's a fact. Some trucks in northern regions used to cover the front with a leather blanket. This leather served as a "windshield," similar to the windshields used on electric bikes to cover the legs, aiming to prevent cold wind from contacting the engine radiator. Excessively low temperatures can indeed prevent the engine from reaching its optimal operating temperature, leading not only to the inability to use the heating system but also to the engine failing to achieve the ideal temperature required for optimal thermal efficiency, resulting in increased fuel consumption.
I'm quite interested in cars and often study various components. The mesh at the front of the car, which we commonly call the front grille or sometimes the air intake grille, isn't just designed for looks—it's primarily for engine cooling. When the engine runs, heat builds up in the engine bay, and air flows through the grille to help cool it down; otherwise, overheating issues can occur. The front grille of many car models also represents the brand's style, like Mercedes' diamond grille or Lexus' spindle grille, which are highly recognizable design elements. Additionally, during daily driving, the grille can easily get clogged with leaves or dust, especially on rural roads, so I often remind myself to clean it regularly to avoid affecting cooling efficiency. On modern cars, some even feature automatic adjustment functions that can open or close the grille vents as needed to optimize airflow and fuel efficiency, which is quite smart.
