Heat Pipe Assemblies

Since 1970 Aavid has been on the forefront of heat pipe technology and it continues to push the boundaries of the technology today. As electronics have become smaller and more powerful, heat pipe technology has become much more prevalent across all industries. Aavid is uniquely equipped to meet all industry needs from the high volume production Consumer Electronics to the intense research and development for Aerospace & Defense.

Aavid manufactures its own heat pipes and maintains strict quality standards to ensure longevity and reliability. Heat pipes capabilities also include loop heat pipes and high temperature heat pipes. Aavid has been performing heat pipe and loop heat pipe life testing on a variety of material systems and heat rejection conditions for over 40 years. Material systems and heat rejection conditions include copper-water, copper-water sintered powder, copper-methanol, aluminum-ammonia, inconel-sodium, natural convection, forced convection and liquid cooling.

With over 300,000 hours of life of continuous, ongoing life testing on copper-water-sintered power heat pipe systems, Aavid has developed proven manufacturing processes that ensure product lifetime and reliability.

Heat Pipe Sizes

The most popular heat pipe diameters for Aavid embedded heat pipes and heat pipe assemblies are 3mm, 4mm, 6mm, 8mm, and 9.5mm. However, Aavid manufactures commercial heat pipes up to 15.88mm and offers custom sizes. Typical lengths range from 76mm to 457mm (3in – 18in).

Materials and Working Fluids.

Although Copper and Water are the most common material and working fluid respectively, Aavid has experience working with a wide range of materials and fluids to meet more stringent temperature and application requirements.



Aavid works with all wick structures. Standard Aavid heat pipes contain a sintered copper wick, however grooved or mesh wicks can be designed in.


With specialized bending methods, Aavid can achieve extremely tight bend radii for complex shaping. For specific industries and applications such as Crystal Growing and Vapor Deposition, Aavid also offers specialized annular heat pipes.

Heat Pipe Kits

For experimentation and learning with heat pipes, Aavid has developed Heat Pipe Demonstration Kits. These kits are designed to enable engineers to design and build their own heat pipe solutions that they can test in their labs for prototyping purposes or just to see how they work. The smaller Discovery Kit is best for small groups and students while the larger Exploration Kit is best for use in the lab or for multiple prototypes.
