Decades of Experience in Research and Development

With decades of experience, dedicated resources for research and development, and design centers specially equipped for the development of two phase solutions, Boyd is uniquely positioned to tackle any thermal challenge. From simple embedded heat pipes to extraordinary two phase thermal systems utilizing multiple advanced technologies and materials, Boyd offers the full range of integrated solutions.

Heat Pipes & Heat Pipe Assemblies

Boyd Corporation is one of the few global organizations with dedicated resources to every aspect of heat pipe design and production, from R&D for new designs and materials to high volume production of fully integrated heat pipe assemblies. Heat pipe capabilities also include loop and high temperature heat pipe design and manufacture. Boyd manufactures its own heat pipes to maintain strict quality standards. Our engineering teams have been running heat pipe and loop heat pipe life testing on a variety of material systems and heat rejection conditions for over 40 years. This ensures our heat pipes’ longevity and reliability, including over 300,000 hours of continuous, ongoing life testing on copper-water-sintered powder heat pipe systems. Other material systems and heat rejection conditions include copper-water with different wick structures, copper-methanol, aluminum-ammonia, inconel-sodium, natural convection, forced convection, and liquid cooling.

Vapor Chambers & Vapor Chamber Assemblies

Boyd Corporation has taken this concept further in the development of specialized air cooled heat sinks that incorporate vapor chambers in the fins as well as the base. Attached to the vapor chamber blades are high density rolled and louvered fins, resulting in an isothermal, high surface area air cooled heat sink for high performance cooling. Vapor Chambers can be manufactured with a variety of materials and working fluids. This includes our Ultra-Thin Copper-Water and Titanium-Water Vapor Chambers for high density cooling in applications such as PEM fuel cells and low profile consumer and mobile electronics.

Thermosiphons

For additional cost savings, Boyd offers advanced engineering and streamlined manufacturing that enables one shot brazing. Boyd has also developed loop thermosiphon solutions that offer passive liquid cooling for more reliable high-power cooling.

Immersion Cooling

To improve heat transfer from the heat source to the liquid, evaporators or boiler plates are installed in lieu of a heat sink or liquid cold plate. These boiler plates provide additional surface area to boil local liquid, which captures heat from the device and carries it away as the boiled bubbles rise away from the board. As a global pioneer in liquid and two phase cooling, Boyd has developed and manufactures boiler plates using techniques refined from our decades of experience with two phase components. Boiler plates utilize a variety of construction types and geometries, and Boyd continues to research and develop flexible, integrated solutions.
