• Reduces thermal resistance, as part of a complete cooling solution, allowing cooling efficiency gains up to 30% over heat pipes
• Flat & ultra thin for space constrained environments (starting at 1.5mm)
• Very large heat dissipating surface area for superior performance within an overall cooling solution (up to Width = 70mm and Height = 500mm)
• Uniform heat spreading for minimizing hot spots from high heat flux devices
• Design versatility
  • Ability to mount directly on heat source (eliminating a base plate)
  • Easily integrates with complementary cooling components (fins or fans)
  • Bendable (both horizontal and vertical)
• No moving parts or pumps means zero noise or power consumption

Celsia Nanospreaders™ can be made into a wide range of design configurations

1.  Bent or Stepped: Using a nominal 10mm bend radius, Nanospreaders™ can have bends that span a range from simple offsets to complex

2.  Embossed: A common design requirement when the heat source is recessed. A typical embossment dimensions is 25mm x 25mm x 0.5mm high. The backside of the Nanospreader™ remains flat for optimal connection to the fin stack

3.  Used as part of a fin array: stamped fin arrays are soldered directly to the vapor chamber to assure a robust thermal and mechanical attachment while large extruded arrays use thermally conductive epoxy.

• NanoSpreader vapor chambers can be produced as thin as 1.5mm, as long as 200mm, and as wide as 85mm, although typical applications are between 20-50mm wide, 50-100mm long and 2.5 – 3.5mm thick
