What is the main advantage of having an electric cooling fan compared to a directly driven fan?

A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated.

What is an advantage of an electric fan compared to a mechanically driven fan?

An electric fan completely removes the mechanical load of spinning the fan from the engine. It places an additional draw on the electrical system, but this is a more efficient means of spinning a fan, and it has a smaller impact on engine drag.

What are two advantages of electric cooling fans?

Advantages include:

  • They move more air for better cooling. Unlike a clutch fan, they turn at 100% of the water pump speed.
  • They free up top-end power. They are lighter and have less drag, especially at high rpm.

What is the difference between an electric cooling fan and a clutch fan?

When compared to an electric fan, fan clutches are quite inefficient. … The benefits of a Thermatic Fan lay in its ability to provide constant air flow, improved fuel economy, better air-conditioning performance, cooler engine running and increased engine power.

Is mechanical or electric fan better?

As the name suggests, electric fans are powered by your vehicle’s electrical system. Although they will place an additional draw on the electrical system, they are a more efficient alternative to mechanical fans and don’t cause the dreaded parasitic horsepower loss.

How much HP does an electric fan free up?

In contrast, the use of electric fans allow for fan reversal, which keep the heat exchangers clean while cooling with much lower power needed than the mechanical fan. In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine.

What is the benefits of electric fan?

A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated.

What is the disadvantage of electric fan?

Increased complexity and maintenance. Increased cost as fan packages may cost more than just adding material in smaller units. Additional energy losses and noise when fan motors are operated in higher loads.

Do electric fans give you more HP?

So essentially the electric fans take 1/2 horsepower. The mechanical to electrical conversion in the alternator to drive the electric fan is not 100% efficient, so the engine will have to make slightly more power to provide the electric fan the same horsepower.

Do radiator fans push or pull air?

Electrical fans can either push air through the radiator or pull air through it. A pusher fan sits in front of the radiator. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator. A puller fan on the other hand sits right behind the radiator.

Can you run a clutch fan and electric fan?

You can run both but 2 won’t cool it any better. If its a rock crawler that doesn’t see mud or water I wouldn’t bother with the e-fan. Just build a good shroud for it.

Can I replace clutch fan with electric?

They can work, but combining them with a mechanical system isn’t an efficient way to do things. As far as electric fans in general, you just have to take the time to figure out your new system.
