Why are the blades of car radiator fans unevenly spaced?

The oddity is there to lessen fan noise. The uneven spaces creates air pulses that cancels out some of the noise, without lessening the ability of the fan to move air.

Why are car fan blades not evenly spaced?

Unevenly spaced fan is developed to reduce the tones. The fan blades are spaced such that the center of mass is placed exactly on the fan axis to minimize fan vibration. The resulting fan noise is 11 dBA quieter in discrete noise level than the even bladed fan system.

How should radiator fans be placed?

And then shift the top fans to intake as well so we have air coming in from the top and from the front we actually end up lowering temperatures quite a bit more using cooler external.

Does it matter where the fans are on the radiator?

there are no rules. if you had a massive air cooler instead of the rad, the top and rear fans would be ideal as exhaust. they would draw in air from the bottom get hot and exhaust in the rear/top. you have a big donkey water radiator.

Do both radiator fans come on at the same time?

cooling fans

The answer to your question is yes both fans will run when your at 230 degrees, if you have the parking lights on and your at 212 degrees one fan will come on, and when you have the air conditioning on you have one fan on as well.

How do you balance a metal fan blade?

How to Balance a Fan

  1. Step 1: ​Align the Blades. …
  2. Step 2: ​Compare the Blades So They Can Be Ranked Heaviest to Lightest. …
  3. Step 3: ​Make the Blade Weights Equal. …
  4. Step 4: Move the Blades As Far From the Motor As Possible.

Should the radiator fans push or pull air?

A Push configuration is more efficient in cooling when its blowing cool(er) air from outside the plenum through a radiator. A Push also makes your build louder. In Pull configuration the fan or fans are drawing an air stream out of the radiator.

How do you orient a radiator fan?

Align the fan holes to the radiator holes and use the longer screws that come in a package one pro tip always think ahead about the cables. And where they will pass through the case.

How far should the fan be from the radiator?

The fan is designed to create negative pressure behind the radiator to pull air through. But the farther away the fan is from the radiator, the less effective it becomes. Flex-A-lite recommends that the fan blades be within 1 inch of the radiator and no more than 2 inches away. But that may not be enough.

What are the two fans behind the radiator?

The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser. On many vehicles, there may be two fans: a main cooling fan for the radiator, and a second fan for the condenser. Both fans should come on when the A/C is on.

How do dual radiator fans work?

Dual Radiator Fan- dual fans are assembled in two’s. They operate together to move air through the radiator core, providing a more effecting cooling effect. Dual radiator configurations are suitable for large engines that need a higher CFM rating.

Can a car work with only one fan?

If you’re moving it will be fine. The problem starts when you stop and sit in traffic. At that time you won’t have any airflow over the radiator and that’s not good. Normally the fan would engage at this time, providing airflow.

How long can I drive without a radiator fan?

Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage.

Does radiator fan affect fuel consumption?

Cooling fans can consume up to 10 pct of an engine’s fuel.

Is a cooling fan the same as a radiator fan?

The cooling fan is also known as a radiator fan because it’s mounted directly to the radiator in some engine layout. Typically, the fan is positioned between the radiator and engine as it draws heat to the atmosphere. In front-wheel cars, the cooling fan used is an electrical component powered by the battery.

Are electric radiator fans better than mechanical fans?

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. Here are a few other advantages of electric fans: Consistent cooling—they maintain their airflow at all times. Reduced water pump wear.
