iPhone 17 invitation letter contains a secret blogger: heat dissipation is stable

Apple’s new product launch conference is scheduled for 1 a.m. Beijing time on September 10. Netizens discovered that the logo on Apple’s poster looks very similar to a thermal image, suggesting that the heat dissipation of the iPhone 17 series will be greatly upgraded.

Blogger Dingjiao Digital said that the orange-red color representing heat in Apple’s press conference poster gradually dissipated, emphasizing that the iPhone 17 series has super stable heat dissipation.

According to leaks, Apple’s iPhone 17 Pro and Pro Max models will use VC liquid cooling (vacuum chamber heat sink technology) for heat dissipation for the first time, and its heat dissipation performance will be significantly better than the graphite sheets used in previous iPhones.

According to the information, VC stands for Vapor Chamber, also known as heat spreader. It adopts a vacuum design. When heat is transferred from the heat source to the VC cavity, the coolant in the cavity begins to vaporize after being heated. The liquid vaporizes and absorbs heat, and its volume rapidly expands to fill the entire cavity. When the gaseous substance contacts a relatively cold area, it will condense and eventually release the heat absorbed before. This process will repeat itself in the cavity.

In terms of industrial design, the iPhone 17 Pro series will adopt a large horizontal matrix design, with the rear triple camera on the left and the flash and LIDAR laser scanner on the right.

In terms of core configuration, the iPhone 17 Pro is equipped with an A19 Pro chip, a 24-megapixel front camera, three 48-megapixel rear cameras, 12GB of memory, a 120Hz high refresh screen, and pre-installed iOS 26 system.
