Welcome back to Bugging Shield Series, the series is designed to help you to get maximum satisfaction with your investment on a tech product. Today we will be checking out why cooling is the protector of your product. Everyone looks the important specifications while purchasing a new product including the processor or the megapixel count, clock speed of a processor among others. Having said that, the cooling mechanism is also very important.
In the current age, heat is no longer just an inconvenience that makes your palms sweaty but it is actually the primary killer of lithium-ion batteries and silicon processors. In this case, we need to learn about the firefighters and they are Vapor Chambers and Heat Pipes. These two elements can offer some extra lifespan for your tech product.
The Science of the “Silent Killer”
You must understand that excessive heat causes “thermal throttling,” where your device intentionally slows itself down to prevent permanent damage. Moreover, heat accelerates chemical degradation in your battery. A phone that consistently runs at 45°C (113°F) will lose its battery capacity twice as fast as one that stays at 35°C.
To protect your device, you need to move away heat and for that you require cooling mechanism.
What is a Heat Pipe?
Heat pipes have been the backbone of laptop cooling for decades and they are now available on smartphones. It works like when your CPU gets hot, the liquid at that end of the pipe turns into vapor. This vapor zips down the pipe to the “cool end”, where it releases the heat and turns back into liquid. It is worth mentioning that the heat pipes are incredibly flexible. It can bend, flatten, and route them around other components like a highway system.
There is a limitation as the heat pipes move heat in one direction—from point A to point B. But if your device has various “hotspots” (like a CPU, a GPU, and an AI NPU), then it will be failed.
What is a Vapor Chamber?
Here comes the real hero, a Vapor Chamber (VC) is a massive open plaza. It is a VC is a flat, sealed metal plate. It can actually spread the heat in a straight line, it spreads the heat in two dimensions across its entire surface area. So the vapor chambers are significantly more efficient at “soaking up” heat from massive chips. The flagship devices are loaded with massive vapor chambers that cover almost 50% of the phone’s internal surface. So it is good to have a device with vapor chambers.
How to Check Before You Buy
Manufacturers don’t always put “Vapor Chamber” on the box, but you can find it with a little digging. You must use the help of YouTube videos and check out the “teardown” video. If you see a large, copper-colored plate behind the screen, that’s a Vapor Chamber.
Conclusion
So a cooling mechanism is equally important as other specifications and features of a device. If you have a fast processor without an efficient cooling mechanism, then it will be useless.
