radiaatoriventilite

Radiaatoriventilite, or radiator fans, are essential components in many cooling systems, particularly within vehicles and HVAC units. Their primary function is to increase the flow of air through a radiator or heat exchanger. This enhanced airflow is crucial for dissipating heat generated by engines, electronics, or other thermal processes. In automotive applications, a radiator fan typically draws cool air through the radiator's fins when the vehicle is stationary or moving at low speeds, where natural airflow is insufficient. As vehicle speed increases, the natural airflow often becomes adequate, and the fan may disengage or operate at a lower speed.

There are two main types of radiator fans: mechanical and electric. Mechanical fans are directly driven by the engine's crankshaft via a belt and pulley system. Electric fans, on the other hand, are powered by the vehicle's electrical system and are controlled by sensors that monitor coolant temperature. Electric fans offer greater flexibility in operation, allowing for more precise temperature control and improved fuel efficiency by only operating when needed. Radiator fans can be constructed from various materials, including plastic or metal, and are designed to move a significant volume of air efficiently. Their proper functioning is vital for preventing overheating and ensuring the longevity and performance of the systems they serve.
