Heat Pipes are a reliable method for transporting heat quickly and effectively. By utilizing the high heat capacity of two-phase water cooling in a versatile copper package, copper-water heat pipes are a popular component in a wide variety of thermal management solutions across broad range of industries.

Boyd Corporation has pioneered heat pipe development and solutions. We have set the world’s standard for commercial application of this passive, highly conductive two-phase heat transfer device for 50 years. Boyd heat pipes are designed for high heat load or gravity sensitive applications where reliability and long life are critical.

Using water as the internal working fluid, the Boyd 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. Ductile copper walls and wick enable bending or flattening to meet an application’s thermal and geometric requirements. This can be used to reduce overall height, increase surface contact, or route heat pipes around keep-out areas like mounting hardware.

Copper-water heat pipes are often integrated into thermal management assemblies to improve effective conductivity and efficiency, improving overall system performance. By using epoxy, solder, or a mechanical interference fit, Boyd’s copper-water heat pipes can be integrated into other components to create heat transport heat pipe assemblies or heat spreading heat pipe assemblies that are more customized to your specific application.
