Heat Pipe Solutions: Copper-Water

For superior power density capacity (50 W/cm2) regardless of gravity or orientation, both commercial and military thermal designers turn to Aavid's high-performance copper-water heat pipes.

Aavid’s copper-water, sintered powder wick heat pipe technology development set the world’s standard for commercial application of this passive, highly conductive two-phase heat transfer device. Aavid heat pipes are specifically designed for applications in which high heat loads or gravity present thermal challenges and where reliability and long life are critical. The Aavid copper-water heat pipe has a sintered copper powder wick structure that operates flawlessly even against gravity and is rugged enough to withstand numerous freeze-thaw cycles and temperatures ranging from -55° to 180°C.

Using water as the working fluid, the Aavid copper-water heat pipe smoothly moves heat from the heat source to where the heat can be managed more effectively through dissipation to air, liquid, or radiated to space. The copper-water heat pipes are often integrated into custom metal heat sinks or cold plates to improve the effective conductivity and efficiency, improving overall system performance. Aavid’s copper-water heat pipes can be integrated into heat sinks, cold plates, extended surfaces through epoxy, solder or mechanical interference.

Life and Reliability

Aavid Thermacore has been designing, developing, and manufacturing sintered copper, powder wick copper-water heat pipes longer than any other company in the world. With tightly controlled manufacturing processes backed by product field experience, Aavid can guarantee that our integrated heat pipe assemblies will last well over 20 years. Today, Aavid has one of the world’s largest collection of heat pipes on life test. With more than 200 heat pipes using various material systems and working fluids on continuous life and reliability testing, Aavid has gathered more than 40 years of life test data (>350,000 hours).
