What is Enclosure Cooling Fan?
An electrical enclosure cooling fan is an electromechanical device, which uses rotating blades or vanes to displace hot air from electrical enclosures.
Normally, electrical fans displace hot air in the enclosure, while replacing it with cool air from outside.
This action results in a cooling effect in the electrical enclosure and its contents.
How Does Electrical Enclosure Cooling Fan Fail?
Electrical cooling fans may fail due to many factors such as:
i. Mechanical damage of the blades, electrical connections or fan system
ii. Due to wear, brought about by aging
iii. Working conditions – electrical enclosure cooling fans turning faster are likely to wear (fail) within a short period of time.
However, an electrical enclosure cooling fan will not fail abruptly.
It is a gradual process.
But still, with proper maintenance procedures, enclosure cooling fan can serve you for a long time.
Can Electrical Enclosure Fans Provide Economical Cooling Mechanism?
Yes, but for basic level cooling.
In most cases, a fan filter unit provides economical cooling when:
- Ambient temperature is less than electrical components operating temperature
- Environmental conditions are not harsh, such as extremely humid or temperature conditions.
Air conditioner and fan
For some situations, going for more advanced cooling systems such as enclosure air conditioner will be more economical.
How Do You Select Fan for Enclosures?
Before you buy a fan for electrical enclosures, you should consider the following:
i. Consider the type of material for the fan (choose either plastic or metal filter fans)
ii. Specify electrical enclosure fans standard requirements such as CE, CCC, NEMA and IP rating
iii. Know enclosure fan CFM
iv. Consider working conditions and environment
v. Calculate the number of heat components in the enclosure generate
vi. Understand enclosure cooling requirements
vii. Know other fan specifications such as size, blade shape, RPM, efficiency, power, etc.

What is CFM of a Fan?
CFM refers to cubic feet per minute when you are dealing with fan systems.
Basically, it quantifies the amount of airflow a fan can handle within a specific time.
Therefore, it is an essential aspect of the electrical enclosure fan rating.
A reason why you can also refer to CFM as a volumetric airflow.
In short, you can get the value of the fan CFM by:
In case you want to learn more about fan systems calculations, here are some useful resources for you:
How Do You Size Cooling Fan for Electrical Enclosure?
You should know the following:
i. Amount of heat you want to remove from the electrical enclosure or power the electrical components dissipate in watts
ii. The temperature difference between acceptable internal temperature and the ambient temperature outside the enclosure
Once you have all these, it will be easier to specify the size or rating of the cooling fan for an electrical enclosure.
It implies CFM is:
Once you have the electrical enclosure CFM, it will be easier to choose the right size of the fan.
Can You Use Fans in NEMA 3r Outdoor Enclosures?
However, even as you intend to maintain free air flow using the filtered fans, it must not compromise the key properties of NEMA 3r enclosures.
- Designed for outdoor and indoor applications
- It’s main use as a junction box
- Protecting enclosure content from snow, and rain
- Protecting enclosure content from dripping water and the formation of ice on the external surface
How Do You Calculate CFM of Electrical Enclosure Fan?
You can calculate the CFM of electrical enclosure fan using this formula:
How Does Electrical Enclosure Fan Work?
Once you power on electrical enclosure fan, its fins or blades will begin to rotate.
Through this rotation, the fan will draw in filtered ambient air, which it will distribute within the electrical enclosure.
As the cool air flows into the electrical enclosures, the fan will force the hot air out of the cabinet through the exhaust vent.
Through this air movement, also called forced convection, the fan will remove all unwanted heat from the enclosure.
At the same time, the exhaust system of the electrical enclosure may have a filtering system.
This creates a reasonable resistance to the flow of air leaving the electrical enclosure.
Consequently, it slightly increases the enclosure pressure, which helps to:
i. Maintain the desired operating temperature for enclosure components
ii. Prevents particulate matter or dust from entering the electrical cabinet
For efficient cooling, you should choose electrical enclosure fans with low energy consumption and ensure maximum airflow.
How Do You Calculate Heat Dissipation in Electrical Enclosures?
Heat dissipation is a process of heat energy transfer.
Therefore, in electrical enclosure thermal management, you should use a suitable cooling mechanism to control heat dissipated within the cabinet.
Here is how you can calculate heat dissipation of electrical enclosures:
a) Calculate the efficiency of all electrical components in the enclosure
It is virtually impossible to find an electronic component that is 100% energy efficient.
In most cases, the efficiency will range from 93% to 98%.
Implying, the amount of electrical energy an electronic component converts to meaningful “work” will be less than the supply (the amount it receives from the mains).
b) Add heat lost by all electrical components in the enclosure
At this point, you will add an amount of heat lost by individual components, whether VFD circuits, conduction bars, electrical components, control circuits, etc.
c) Consider environmental factors and type of enclosure
To get the total amount of heat dissipated within an electrical enclosure, you should consider other aspects such as:
i. Type and color of the electrical enclosure
ii. Environmental temperature conditions
iii. Possible thermal losses to the environment
Clearly, determining accurate heat dissipation in an electrical enclosure is a systematic process that requires careful evaluation.
However, to make the process simple, you can let the electrical enclosure manufacturer estimate it for you.
How Can You Calculate Temperature Rise in Electrical Enclosures?
Of course, you can use a measuring instrument to determine the temperature of an electrical enclosure.
It is a common method, which is easier to integrate with modern control systems.
For calculations, first, determine the power input per feet in the electrical enclosure:
Second, you will use the graph below to determine the rise in temperature within the enclosure.
Note: The graph is courtesy of Border states.
Your electrical enclosure manufacturer may provide a graph for you.
Temperature rise in an electrical enclosure
Once you have the values from the first calculation above, do the following:
i. From the horizontal axis, choose an appropriate power input depending on your calculations above.
Then draw a line to intersect with temperature curve (depending on the type of the enclosure)
ii. You draw another line to intersect the vertical lines (on the two extreme ends of the table).
You can determine the temperature rise in either ℃ or ℉.
What is Electrical Enclosure Internal Heat Load?
It is the total amount of electrical heat enclosure dissipates the plus amount of heat due to the external environment.
This is how you can calculate total heat load for your electrical enclosure:
i. Calculate the amount of heat within the electrical enclosure in watts.
ii. Determine the amount of heat from the external environment
iii. For total heat load, add internal and external temperatures
Is There IP Rating for Electrical Enclosure Fans?
Yes, you can get Ingress Protection rated fans.
Some of the most common IP ratings for electrical enclosure fans include IP55, IP56, and IP68.
You can use the fans with IP Enclosures.
How Do You Troubleshoot Electrical Enclosure Cooling Fans?
If the electrical enclosure fans are not working, you should try the following:
i. Ensure the fan’s switch and control is in ON position
ii. Check the electrical connections if they are damaged or not
iii. Check is the fan fuse is working
iv. For those integrated with sensors, ensure the sensor is working and correctly configured
v. Check fan for possible wear
vi. You can grease and clean fan in case it has a lot of dirt
vii. Check the drive shaft; it could be lost
viii. Tighten contact screws
ix. Check if the polarity has not been interchanged
If any of these is not working, you need to contact the electrical enclosure fan manufacturer.
How Does Electrical Enclosure Fans and Air Conditioners Compare?
|Electrical Enclosure Fan||Electrical Enclosure Air Conditioner|
