How It’s Made: Vapor Chambers — Thin Heat Spreaders

Vapor chambers are ultra-thin heat spreaders that move heat using phase change. Inside a sealed copper plate: a sintered wick holds working fluid; hotspots boil the fluid to vapor, which flows to cooler regions, condenses, and returns through the wick by capillary action—spreading heat with minimal temperature drop. Manufacturing pipeline: copper sheet forming → wick sintering (powder + furnace) → cavity machining → fill/evacuate under vacuum → hermetic seam welding → helium leak test → flatness & thermal performance QC. We compare vapor chambers vs heat pipes, wick porosity & capillary limit, orientation effects, and why phones, GPUs, servers, and VR headsets rely on them for silent, high-density cooling. #HowItsMade #Thermal #Engineering #Electronics
