Radiator fan
by GLADY REIGN
In an environment wherein heat must be maintained at a certain temperature level, a certain form of a cooling system is a must. A most appropriate scenario would be the CPU of a computer, as its extreme processing capability needs the heat sink and a fan to dissipate high temperature. The same principle certainly applies to the engine of a vehicle, with its need for a radiator and radiator fan to maintain its temperature requirement for optimum performance.
Automotive experts believe that the efficiency of a vehicle��s engine is partly credited to its cooling system and its corresponding essential components. One such vital part is the radiator fan. Mounted on the back of the radiator closest to the engine, the radiator fan is also known by other names such as the automotive fan or condenser fan. In technical terms, the radiator fan is a rotating device wherein its main function is to keep the airflow towards the direction of the radiator. This process is implemented on excessive heat-emitting periods of the engine, such as while the vehicle is in a slow motion, or has entirely stopped but with the engine still running.
The radiator fan has its own components consisting of the fan motor, fan belt, fan clutch, fan shrouds, fan blades and other minor parts. Earlier models made use of the mechanical type of radiator fans, wherein a fan belt is connected to a fan clutch that in turn triggers motion on the radiator fan. The turn and pace of fan clutch is then quite proportional to the rotation of the radiator fan. Later on, through the car manufacturer��s penchant for technological advancements, the mechanical type would evolve into the electrical type of radiator fan. This revamped radiator fan is normally mounted directly to the radiator and is controlled by electronics attached to a heat sensor. This sensor then supervises engine temperature and sends this information to a computer chip, which in turn determines if the fan should be closed or opened, as well as the necessary adjustment on speed rotation.
A radiator fan with a continuous rotation even under cool engine temperature is an indication of a busted component. Either the fan��s electronic sensor has encountered problems in its system or the engine is running under unreasonably extreme heat. A damaged or inoperative radiator fan will result in overheating of the engine, especially when the vehicle is immobile. Thus, it is imperative that check-ups and proper maintenance be conducted regularly.
