To assist with that dissipation, Apple connects the cooling part of the chamber to the unibody and battery plate, so that heat is lost more swiftly. Therefore, the hermetically sealed vapor chamber inside the new iPhone is essential to the cooling system.
How does it work?
According to Apple, it works like this: “Deionized water is sealed inside the vapor chamber, which is laser-welded into the aluminum chassis to move heat away from the powerful A19 Pro, allowing it to operate at even higher performance levels. The heat is carried into the forged aluminum unibody, where it is distributed evenly through the system, managing power and surface temperatures to deliver incredible performance while remaining comfortable to hold.”
If you watched Apple’s iPhone presentation earlier this month, you’ll be aware the vapor chamber itself is very thin and relatively wide in terms of the scale of the device. That’s deliberate, as it gives the best possible performance by volume within the shape of the phone.
