Custom Heat Sink Manufacturer
Vapor Chamber & Heat Pipe Heat Sinks

Celsia is a custom heat sink manufacturer specializing in vapor chamber and heat pipe thermal assemblies. Heat sink design and optimization is done jointly between our US headquarters and Taiwan facilities, while heat sink manufacturing is done exclusively at the latter. ISO certified and compliant with ITAR, RoHS, & REACH.

Heat Sink Manufacturer Using Two-Phase Cooling Technologies

Heat pipes or vapor chambers are used in all custom heat sinks manufactured by Celsia.

Heat Pipe Wick Types

Heat Pipes

Heat pipes are ideal for transporting heat to a remote heat sink. 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 heat to a local heat sink.

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.
