Vapor Chamber Heat Sink
- Superior Heat Spreading: Vapor chamber efficiently spreads heat across a large planar surface via two-phase (liquid-vapor) phase change, significantly reducing hot spots.
- Ultra High Thermal Conductivity: Delivers thermal conductivities several orders of magnitude higher than solid metals-ideal for demanding thermal applications.
- Thin, Lightweight Design: Extremely slim profile and reduced weight make it perfect for compact and mobile electronics.
- Uniform Temperature Distribution: Acts as an isothermal heat spreader, ensuring even temperature across multiple heat sources.
- Compatible with Fin Structures: Supports integration with fins (e.g., stamped or zipper fins) for enhanced convective cooling.
- Gravity-Insensitive Operation: Flat planar design with internal support enables performance in various orientations.
- Customizable Materials and Geometry: Can be fabricated in copper or stainless steel, planar or 3D shapes to suit design constraints.

Vapor Chamber Heat Sink-FAQ's
What cooling benefit does vapor chamber offer compared to solid metal?
Vapor chambers offer thermal conductivities far beyond solid copper or aluminum, resulting in much faster and more uniform heat spreading.
How thin can the vapor chamber be?
Ultra-thin vapor chambers as thin as around 0.2 mm can be fabricated for compact applications.
What materials are used?
Commonly copper-water assemblies are used up to ~250 degrees C; stainless steel is available for rugged applications.
Can you attach fins?
Yes, vapor chambers can be soldered or epoxied to various fin types, such as stamped or zipper fins-solder offers better thermal performance.
Does orientation matter?
No-thanks to internal support structures, vapor chambers perform well regardless of gravity or orientation.
Are wick-free options available?
Yes, wick-free designs using surface wettability patterns allow ultra-thin construction with efficient fluid return.
Is temperature uniform across the chamber?
Yes-vapor chambers provide isothermalization, keeping multiple heat sources at similar temperatures.
What are integration options?
Custom shapes including curved or 3D forms can be produced, offering versatile integration into diverse device geometries.
