The cooling fan is employed in almost all vehicles to circulate air through the radiator so that it can discharge engine heat into the surrounding air. With the launching of electric cooling fans and fan clutches, automotive fans become more efficient since they operate only when they are needed. The operation of the vehicle’s air conditioning system was also enhanced by the electrical cooling fans. At usual road speeds, mechanical fans basically freewheel and the electric fans do not operate. This air that passes through the radiator due to vehicle movement is all that is required for ensuring heat exchange.
There are two different types of cooling fans that may be employed in the vehicle’s cooling system. Cars traditionally feature mechanical fans that are belt-driven, which depends on the engine to turn them. These fans are still utilized today on some light trucks and cars. Mechanical fans now have a temperature-sensitive fan clutch which engages and disengages the fan to the various working conditions. One of the cooling fan components that we always tend to overlook is the fan motor. It is a device made to give power to the fan whenever it is needed. Fan motors need to be energy efficient as possible and it should be durable enough since its job is a hard one. Starting a fan isn’t that easy and motorizing it with reduced power doubles the difficulty. It can surely cause the fan motor to fail too soon and to necessitate replacement. When hunting for replacement fan motor, be sure to find out approximate motor lifespan and consider that before deciding on a certain unit. Also remember that your cooling system’s specifications might favor some fan motor features over others. When you are sure as to which motor features will work best for your specific application, then its time to look and settle your hands to a particular fan motor.
