Apple Boosts Cooling Parts for New iPhone Models

Apple is ordering more vapor‑chamber cooling units, hinting that the company may rely on this technology in future devices. The move coincides with rumors of a foldable iPhone and a special anniversary edition slated for 2027.

How Vapor Chambers Work

Vapor chambers were first introduced in the iPhone 17 Pro to prevent overheating. The system turns a small amount of liquid into vapor near the heat source, then lets it condense elsewhere to spread warmth evenly across the device.

Growing Demand

A social‑media leak indicates that Apple’s new orders could double its previous supply of these cooling parts, suggesting preparation for higher performance demands in upcoming models.

Production Scale‑Ups

• Foldable phones: Apple has asked suppliers to build roughly 10 million units, up from an earlier estimate of 7‑8 million.
• iPhone 18 Pro/Pro Max: The company plans about 70 million units, all likely to feature vapor‑chamber cooling.

Path to Launch

The increased production follows reports that Apple has resolved earlier hinge problems and improved manufacturing yields, clearing the way for a September launch.
