The Benefits of a Car Electric Fan
A cooling fan is critical for preventing engine overheating, especially during stop-and-go driving. A well-designed electric cooling fan can dissipate heat without affecting horsepower or fuel economy.
While mechanical radiator fans mount on a pulley, an electric fan is controlled by the car computer. This means the fan only operates when coolant temperature reaches a specific level. This reduces parasitic power loss from turning the fan.
They are quiet
A car electric fan is much quieter than the mechanical type. It also doesn’t rob the engine of horsepower, which is an important benefit for racing vehicles. Another advantage is that it can operate when the engine isn’t running. This is especially helpful for drivers who need to drive their cars in the summer when they don’t want to start the engine. The best electric fans are designed to be as effective as possible. They have curved blades, which reduce noise while allowing them to move more air than straight-blade fans.
A curved fan can also be more efficient, as it moves more air at a lower RPM than a straight-blade fan of the same size. There are many benefits of using an electric fan in your car, including improved cooling, a cooler air temperature inside the radiator, and reduced vibration and noise. In addition, they require less maintenance than belt-driven fans.
Most electric fans have a built-in fuse, which blows if the circuit is overloaded or damaged. This is a safety feature that protects the fan from permanent damage. The fan circuit also incorporates a switch, which shuts off the engine when the fan car electric fan fails. This allows you to get the problem fixed before it becomes a major issue. You can choose between single and dual electric fan setups, but a dual fan is the most effective option for most cars.
They are easy to install
Car electric fans offer a number of benefits that can improve engine performance and help maintain coolant temperatures. These include better cooling efficiency, more precise engine temperature control, and the ability to operate only when needed. They can also be used on hot days to bring the engine up to operating temperature more quickly, and during drag racing to keep the engine at optimum temperature for consistent performance.
Adding an electric fan to your classic car is a simple process, and there are several ways to do it. You can either use a factory water pump fan or a new SPAL fan kit with an additional relay that you install in the engine compartment. Then, you can wire the relay to the car’s thermostat or to a 12V ignition-on source. You can also add a switch to turn the fans on and off when the air conditioning is running.
Regardless of how you choose to wire the fan, all you need is a pair of fuses and some good quality relays. You’ll want to apply dielectric grease to the male and female connectors in order to reduce the risk of corrosion. Then, run the fan ground wires to a convenient location in the engine bay, such as the frame bolt for the brake line bracket. Connect the black fan power wire to the fan relay, and the red fan control relay wire to a hot engine-turned circuit such as the water pump or alternator.
They are not tied to the engine
Car electric fans are not tied to the engine and can be turned on and off independently. They are often used to cool larger engines and modified cars, as they are capable of pulling more air. They are also often used to cool the air conditioning condenser. However, there are several things to consider before deciding which type of fan to buy for your car. For example, you should consider the size of your radiator and the amount of space available for the fans. It is important to make sure that the fans can fit in your radiator shroud and not hit each other, which can cause overheating and damage to your engine.
The traditional mechanical fan is attached to the engine pulleys and is controlled by a clutch that turns on and off when the engine reaches a certain temperature. It can be a good option for older vehicles but is prone to failure. In addition, it requires special tools to remove and replace a failed fan.
Modern electric cooling fans are not connected to the engine and operate independently using a motor and complex wiring system consisting of relay(s), fuse, and sensors. These fans are activated when the computer detects a coolant temperature that is higher than normal and sends a signal to the fan control relay.
They are environmentally friendly
A car electric fan works by drawing power from the vehicle’s electrical system rather than the engine. However, it still needs to move air through the radiator core and coolant, and it must be able to do this at high rpm. In addition, the fan requires more cooling fin area than a mechanical fan, so it is not suitable for all cars.
The best way to select a new electric fan is to choose the one that offers the most CFM (Cubic Feet car electric fan per Minute). This measurement indicates how much air is being pushed or pulled through the radiator core. A push style fan will work well for most applications, but some companies recommend using a puller style in certain cases.
Another important factor is the size of the fan. A large diameter fan will increase the flow of air through the radiator and coolant, allowing it to stay cooler. The fan should also be reversible to prevent radiator clogging. The company Maradyne has tested fans in a Peterbilt 520 cab-over truck and found that the system improved performance significantly and helped to reduce the amount of time the driver had to back flush their radiator.
Another benefit of an electric fan is that it does not steal horsepower like a mechanical fan, so it can improve fuel economy and engine hp. A car electric fan can also reduce odors and improve ventilation, which is good for the health of passengers.
