Heat Spreaders & Conductive Chassis

By incorporating an efficient heat spreader or a chassis designed for heat spreading, heat transfer more uniformly to where it can be easily dissipated to optimize your thermal solution.

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. Heat spreaders can also be integrated into complex assemblies or geometries for high performance chassis or enclosures where internal volume is at a premium. Aavid, Thermal Division of Boyd Corporation’s k-Core® technology creates extremely lightweight heat spreaders utilizing encapsulated graphite.

Through precise control over the Coefficient of Thermal Expansion (CTE) of our k-Core® products we 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.



Thermally Conductive, Heat Spreader for High Performance Cooling

Encapsulated Graphite Heat Spreaders

Boyd designs compact and ultra-thin heat spreaders integrating multiple technologies for optimized, cost-efficient heat spreading and dissipation. The more advanced Boyd heat spreaders include our encapsulated graphite which utilizes thermal annealed pyrolytic graphite encased in a thermally conductive alloy such as copper or aluminum. These solutions are light weight, passive and can be manufactured in complex geometries.

Encapsulated Graphite Heat Spreader for Thermal Enclosures

Encapsulated Graphite Chassis & Enclosures

By utilizing thermally conductive metal joining and encapsulated graphite heat spreaders, Boyd manufactures compact, lightweight chassis and enclosures ideal for high power applications with limited space. These enclosures are popular for space and aircraft systems as they add structural integrity and environment protection as well as improved cooling without adding weight. Enclosers can be further optimized with the addition of sealing and protective materials or mechanical additions such as fins or ducting.
