The computers and electronic devices that we all use on a daily basis have some unique wonders inside them. Have you ever built a computer or looked inside one and wondered how those shiny, pointy heat sink fins are made?
Heat sinks are those silver or copper metal fins and porcupine-like blocks found inside computers that help disperse heat so our devices stay cool and perform at their best. We recently stumbled upon a video that shows how heat sinks are made, and it’s much simpler than I expected.
Take a look yourself, but don’t say I didn’t warn you about the nasty noise the machine makes.
While the video above is a few months old, recently appeared on twitter, and I found it fascinating. I always thought heat sinks were milled one at a time, laser cut into weird shapes to fit each PC or electrical component, but no, it’s a simple process that makes a lot of sense.
Apparently, many heat sinks are made by a process known as “cutting,” where a giant machine literally scrapes super-thin layers of copper (or other materials) into fins, then bends them back up before starting over with the next row. .
The workers put a large piece of copper into the machine, turn on some cold water, and press “go.” The machine then slices and dices the copper, like Swiss cheese, instantly creating large heat sinks in minutes. fascinating, right?
From here, the entire copper fin slab is likely to go to another machine where it is cut into individual blocks of the perfect size for each specific application.
So the next time you’re having an intense PS5 or PC gaming session and wondering what helps keep your machine cool and running at higher frames per second, think about this clip.
