In this article, we will discuss more of the cooling system in your car. Basically, the cooling system in any vehicle is made up of the water pump, radiator, radiator fan, and the thermostat.
Before anything else, we need to review some salient points about the radiator fan in your car.
What is the radiator?
Generally, the radiators are identified to be the heat exchangers being utilized in transferring thermal energy for the purpose of cooling and heating. This device is made of a really large amount of cooling surfaces which come with large amounts of air. This eventually allows the spreading of the air through the water to cool it down efficiently.
As you can see, radiators are really critical in keeping the car’s engines to be cool while you drive. The radiator comes with the radiator fan which is a part of the cooling system of your car. This system in your car will lower the temperature of the coolant.
Should the radiator fan malfunctions or breaks down, the coolant will not get cooler quickly and the thermostat of the engine will eventually overheat. Remember, an engine that overheats will require an engine replacement as soon as possible,
Where can you find the radiator fan?
Basically, the radiator fan is located in between the car’s engine and the radiator. Additionally, this device is the one responsible of cooling the engine of the car. These cooling radiator fans are specifically useful and helpful when the car is being driven too slowly to get airflow from the outside environment or when the car is stationary.
Radiator fan types: electric radiator fan vs mechanical radiator fan
The electric cooling radiator fan turns on and off when needed in reference to the internal temperature of the vehicle. This is an improvement since the engine-driven fans that tend to slow down when they are needed the most. As mentioned previously, a failed radiator fan will result into the engine’s overheating.
The Mechanical radiator fan relies mostly on the mechanical energy from the engine in order to run smoothly and properly.
Generally, there are two main categories of mechanical fans – flex fans and clutch fans.
The clutch fans are under the control of a thermostat and makes use of a clutch to engage and disengage. The clutch dans appears to spin at approximately 30 percent of the speed of the waster pump continuously. The clutch also may appear to limit how fast the fan may spin; it will only turn the fan at a fraction of the water pump speed. Yet, it all depends on the temperature and engine speed.
When should you choose a clutch fan?
There are several reasons why a clutch fan is very useful. The reasons are stated below:
If the mildly or stock modified engines, high performance in terms of cooling ability and applications up to 6,000 rpm.
Take note, flex fans do not use a clutch. Thus, it operates at 100percent of water pump speed instead. This makes the flex fans to be more efficient than the clutch fan type. The flex fans are considered to be lighter than the clutch fans. Most of the time the flex fans do have blades that seem to be flatten out at higher rpms to achieve optimal efficiency.
When should you choose a flex fan?
On the other hand, a flex fan is recommended for the following reasons: a mildly modified car engine, if you need good cooling ability with less drag at higher rpm, lightweight fan and applications up to 8,000 rpm.
Attributes of mechanical fans (belt-driven fans)
This type of radiator fan is recommend for mildly modified street vehicles or stock. However, its main disadvantage may include causing parasitic horsepower loss because the car engine appears to use up a certain amount of power spinning the fan. Eventually, it results to significant power loss for the rear wheels. Thus, the electric fan is more preferred for cars or trucks which are highly modified.
What electric fans are for?
This type of radiator fan is powered by the electrical system of the car. This is more efficient because it does not cause horsepower loss. It also has the capacity to consistently cool the engine by maintain airflow constantly.
