Overview
- A Sony Interactive Entertainment patent, which surfaced Wednesday, describes a vaporization-based heat-pipe system that seals a working fluid inside sintered internal layers to move heat away from chips.
- The filing spells out heat-pipe construction with a sintered body layer and internal cavities that hold the working fluid, and it notes the fluid could be something simple like water.
- Reporting links the patent to lessons from the PS5 launch, when liquid-metal thermal material reportedly leaked onto APUs and motherboards and prompted revised Slim and Pro heat-sink designs.
- Patent authors and analysts say a modular vapor chamber or heat-pipe unit would be easier to fit on an assembly line and would reduce the risk of conductive spills compared with applying liquid metal directly to chips.
- The patent signals an engineering direction but does not guarantee a final PlayStation 6 design, and the filing was first flagged by Tech4Gamers before wider reporting by PlayStation LifeStyle, Wccftech and Kotaku.
