Conduction Cooling

Passive conduction cooling is an essential tool for reliable heat transfer and one of Boyd’s areas of expertise for over 50 years. Thermal Interface Materials are essential for improving air- or liquid- cooled solutions, high conductivity materials like encapsulated graphite heat spreaders help manage high heat densities, and thermally conductive chassis and enclosures, flexible thermal straps, and rugged thermal busses provide reliable heat transport solutions.

Heat Spreaders

Heat spreaders are an ideal solution for rapidly and evenly distributing high density heat loads. Heat spreaders are often used to increase heat distribution to additional surface area like heat sinks or heat exchangers, which improves the overall thermal performance of the assembly.

Thermal Straps and Busses

Boyd is the pioneer in utilizing encapsulated graphite to create lightweight, yet highly thermally conductive solutions. Thermal busses integrated with k-Core® to combine the lightweight benefits of graphite with the strength of copper or aluminum and offer thermal conductivity greater than the encapsulating material.

Thermal Interface Materials

machine cutting thermal interface material

Nearly every thermal management solution requires thermal interface material to decrease the thermal resistance between the heat load and the thermal solution. Thermal Interface Materials (TIMs) come in a wide variety of options that include electrically isolating, compliant, adhesive or tacky, phase change, and reinforced.

Conduction Cooling Solutions Effectively Transfer Heat

Conduction cooling solutions rely on direct contact with materials with high thermal conductivity to effectively transfer heat. Conduction solutions can be simple like thermal interface materials, often a film or silicone pad embedded with high conductivity filler, or they can be more complex solutions like a lightweight aluminum chassis with an encapsulated graphite core.

In addition to a broad portfolio of traditional conduction solutions, Boyd Corporation is the world leader in creating advanced conduction solutions utilizing encapsulated graphite to combine lightweight, highly thermally conductive graphite into either machinable or flexible formats in our k-Core® product line.

Key Benefits

One of the key benefits of conduction cooling solutions is that they are passive solutions that don’t require moving components, meaning high reliability, less wear and tear, and low maintenance.

Heat Spreaders

Heat spreaders can be integrated into complex assemblies or geometries for high performance chassis or enclosures where internal volume is at a premium. Boyd's k-Core® technology and manufacturing processes enables extremely lightweight heat spreaders utilizing encapsulated graphite. Through precise control over the Coefficient of Thermal Expansion (CTE) of our k-Core® products where we can create high performance Thermal Ground Plane (TGP) products. With a matching CTE, Thermal Ground Plane solutions significantly reduce thermal resistance at the die level and prevent shear between surfaces during thermal cycling. Customers can install our CTE matched products directly to their die, whether it’s silicon, silicon carbide (SiC), aluminum silicon carbide (AlSiC), gallium nitride (GaN) or any other material.

Thermal Straps & Busses

By utilizing flexible encapsulant materials like copper foil, aluminum foil, or polyimide film, thermal straps with k-Core® offer increased design flexibility while maintaining performance.
