Apple Routes 2 nm iPhone Duo Cooling Pipe Through Hinge

Summary
Apple said the folding iPhone Duo uses a flexible graphite pipe routed through its hinge to move heat between both halves and expand the area available for dissipation.
The design tackles one of the device’s hardest engineering problems: a foldable body that doubles in thickness when closed, requiring the pipe to survive repeated hinge cycles without losing thermal contact or structural integrity.
The iPhone Duo’s A20 Pro variant also adds a second display engine to run the inner and outer screens simultaneously, while supporting an under-display FaceTime camera on the inner panel.
Built on a 2 nm process, the A20 Pro also uses a new vapor chamber and a “metal over foam” interface material that Apple says creates a direct thermal link between the chip and the cooling system.
