Vapor chamber
Sealed thermal-transfer-device: flat-large heat-pipe med wicking-struktur + working-fluid. Effekt: distribuera värme jämnt över större area än conventional heat-pipes. Standard i premium-GPUs + flagship-laptops + PS5.
Funktion: hot-spot (CPU/GPU-die) förångar fluid → vapor moves to cooler area → condenses → wicks back via capillary-action. No moving parts. Performance: 2-5x bättre than aluminum-heat-spreader för spreading. Nvidia Founders Edition + AMD reference GPUs använder vapor-chambers. Premium laptops (MacBook Pro 16, ROG Strix) inkluderar dem. Cost: $20-100 extra över heat-pipe-design. Failure-mode: rare men dramatic (chamber leak → near-total-cooling-loss). Modern phones: vapor-chamber i high-end Galaxy + Pixel för sustained-performance under gaming.
