Heat Pipe Wick Types

Heat Pipes

Heat pipes are ideal for transporting heat to remote locations. Changes to shape, wick thickness, wick porosity and fluid loading are optimized for each heat sink design. Bending and flattening are common modifications.

One-Piece Vapor Chamber with Embossment

1-Piece Vapor Chamber

One-piece vapor chambers were pioneered by Celsia a decade ago. This unique design is cost comparable to multi heat pipe solutions and allows Z axis bending to form U and L shapes. Great for spreading & moving heat.

Two-Piece Vapor Chamber with Embossment

2-Piece Vapor Chamber

Two-piece vapor chambers can be stamped into any shape along the X and Y axes to mold around crowded components or reduce weight. Surfaces can be embossed up to 8mm to reach recessed heat sources.
