Fahrzeugkühler

Fahrzeugkühler, often translated as vehicle radiator, is a crucial component of an internal combustion engine's cooling system. Its primary function is to dissipate heat generated during the combustion process, preventing the engine from overheating. This heat is transferred from the engine coolant, typically a mixture of water and antifreeze, to the surrounding air.

The radiator is usually made of metal, such as aluminum or copper, chosen for its excellent thermal conductivity. It consists of a series of thin tubes through which the hot coolant flows. These tubes are typically surrounded by fins, which significantly increase the surface area exposed to the air, thereby enhancing heat transfer. As the vehicle moves, air flows through these fins, carrying away the heat. In stationary or slow-moving vehicles, a fan is used to draw air through the radiator.

The coolant circulates from the engine to the radiator via hoses. After passing through the radiator and being cooled, the coolant is pumped back into the engine to absorb more heat. This continuous cycle is essential for maintaining the engine's optimal operating temperature. A radiator cap regulates the pressure within the cooling system, raising the boiling point of the coolant and preventing it from boiling over. Damage to the radiator, such as leaks or blockages, can lead to engine damage if not addressed promptly.
