It may be that you live in a country with an incredibly hot climate – or maybe you’ve just visited one. Either way, it’s probable that at some point you needed to use a fan to keep you cool.
Fans themselves can come in lots of different shapes, sizes and designs, although they’re primarily used for one key purpose – to keep humans cool. It’s important for our health and safety, but did you know that many objects that aren’t living also need to stay cool to survive?
It sounds rather strange, but machines which use electricity can overheat if not cooled sufficiently, leading them to break down. Computers are the most prone to this which is why they always contain a fan which helps to cool the machine by pumping in fresh air. Every year new technology advancements are made but the machinery still needs to fulfil its primary purpose – to work – which it won’t if it keeps overheating. That’s why big software companies need to invest in powerful, efficient fans in order to make sure their computers run constantly, without interruption.
The kind of fans that are used in warehouses and factories to keep computers running are known as industrial fans, and are significantly larger and more powerful than the ones that are used for humans. But that’s with good reason – they have to work a lot harder than humans usually do, and have no other methods of cooling as animals can by drinking water, or sitting in the shade.
For technology companies an industrial fans is often a vital part of day to day operation, and could be the main thing keeping powerful computers working. The two main types that are used in these cases are centrifugal and axial fans.
A centrifugal fan uses what’s called “centrifugal force” to push air around, generated by a rotating dick with right-angled mounted blades. It’s usually used in order to generate air or gas, and there are many different sizes and varieties.
Axial fans on the other hand use an axial force, which means they spin a central hub which has blades radiating out from the middle. These can be huge items, spanning from less than a foot to over 30 feet! The cooling fan tower for the wheel can even get bigger than 82 feet in diameter.
And there you have a very brief introduction to how industrial fans work, and what they’re used for!
