Cooling Fans
Vehicles have
cooling fans that allow them to control temperature and make the vehicle
run smoothly, especially during hot seasons when there the air around
is not enough to go through the radiator core. A cooling fan is also
needed whenever you are not driving fast enough, because it also means
not enough air rushes through the grille of your car.
Fans are usually
mounted on the water pump water shaft, but they may be mounted as independent
units. Every vehicle has at least one fan. That is how vital it is,
but some vehicles have more than one to ensure their cooling systems
are superb. There are belt-powered fans, electric fans, and AC cooling
fans. Electric fans are more modern as they don't have fan belts for
you to keep a constant eye on. They are also quieter and consume less
power than other fans.
Primary cooling
fans use a thermostatic control called a fan clutch to determine the
right speed of their spin. The fan clutch signals the cooling fan to
run faster when heat is accumulating in the engine and tells it to go
slower or stop altogether when enough air is coming through the radiator.
This renders the fan unnecessary.
Cooling fans drain
power from the engine in order to spin, and so they shouldn't be left
to spin all the time. Most fans are made of tough plastic and have four
to six blades, although others have as much as eleven. Often the blades
are enclosed in a fan shroud to keep the same hot air from going through
and around it again.
