Heat Sink Manufacturer Using Two-Phase Cooling Technologies
Heat pipes or vapor chambers are used in all custom heat sinks manufactured by Celsia.
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.
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.
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.
Heat Sink Specialties
Heat Pipe Heat Sinks
Each of the 2.5 million custom heat sinks we’ve manufactured uses heat pipes or vapor chambers whose internal structure is matched precisely to the application.
Difficult Heat Sink Challenges
We solve custom heat sink design & manufacturing problems associated with densely packed electronics, low/no airflow, high ambient temperatures and power densities up to 500 w/cm2. Test us for yourself.
Small to Mid Size Heat Sink Orders
5 – 5,000 custom heat sinks per month are Celsia’s forte. Our wholly owned design and heat sink manufacturing facilities are optimized to deliver the quality, price & performance not found elsewhere.
Stellar Customer Service
Celsia’s goal – provide an unmatched level of customer satisfaction through quick responses to inquiries and 2-4 week turnarounds on design, prototype & heat sink production orders.

Custom Manufactured Two-Phase Heat Sinks
Extruded Heat Sink
Pairing heat pipes or vapor chambers with extruded heat sinks offers a cost-effective and reliable two-phase solution.
Zipper Fin Heat Sink
Allowing for very high fin density, these heat sinks are the most common performance choice for use with heat pipes
Machined Heat Sink
Offering the most design flexibility, and highest cost, CNC machined heat sinks are used when production volumes are small.
Skived Heat Sink
Heat sinks manufactured using this process have excellent thermal properties coupled with high fin aspect ratio and low tooling cost.
Full Heat Sink Assemblies
To streamline installation, complete thermal assemblies can come with attached fans, mounting hardware, and TIM material.
Heat Sink Oddities
When ‘traditional’ heat sink designs won’t work, Celsia can provide square heat pipes, two-phase bricks, or vertical vapor chambers.
