What is the fan behind the radiator called?
What is the fan behind the radiator called?
The fans which are found in the rear or at the back are referred to as “puller fans”. They serve to pull the air from the grille. It then draws the air over the radiator.
Does a radiator need a fan shroud?
If you rely on a belt-driven fan for engine cooling, a fan shroud is a must to pull the air through the radiator. Without a shroud, air will take the path of least resistance, pulling air from over and under the radiator instead of through it.
Are clutch fans better than flex fans?
For high rpm use, flex fans are considered an upgrade over clutch fans. They can be a good choice for modified vehicles turning 6,000 – 8,000 rpm. Advantages include: They move more air for better cooling.
What is the difference between condenser fan and radiator fan?
On some vehicles, for example, only the condenser fan operates with the air conditioner, while only the radiator fan operates based on engine temperature. On other vehicles, both fans can be activated by either air conditioning or engine temperature.
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.
Is it better for radiator fans to push or pull?
Push vs Pull 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. It pulls air through the radiator and has less impact on airflow at high speeds than a pusher fan since it is behind the radiator.
How many CFM do I need to cool a v8?
2,500 cfm
CFM Rating
| Engine Size | Minimum Fan CFM |
|---|---|
| 4 cylinder | 1,250 cfm |
| 6 cylinder | 2,000 cfm |
| Small 8 cylinder (under 302 c.i.d.) | 2,500 cfm |
| Large 8 cylinder (302 c.i.d. +) | 2,800 cfm + |
How to choose the right radiator fan for your car?
When it comes to diameter, you should get a fan that covers as much of the radiator core as possible. Measure the area with the existing fan and shroud removed to find out how much room you have to work with. Larger fans will keep your car idling in the heat for longer period of time without overheating.
Should radiator fan blades be curved or straight?
If you desire a more quiet fan then the curved is the way to go but if you need all airflow possible, go for the straight blades. To get maximum airflow through your radiator core, you should use a fan shroud. A fan shroud ensures that air is moving through the radiator core and not around it.
What does a fan shroud do for a radiator?
A radiator is useless without airflow, a fan shroud helps direct air through the core. Make sure you use one in your vehicle. Manufacturers rate fans by CFM. CFM stands for cubic feet per minute so an electrical fan with a 1,500 CFM rating will push 1,500 cubic feet of air per minute.
What is the CFM rating of an electrical fan?
Manufacturers rate fans by CFM. CFM stands for cubic feet per minute so an electrical fan with a 1,500 CFM rating will push 1,500 cubic feet of air per minute. Follow this general guideline:
