The Next Dimension of Two-Phase Cooling
Boyd has taken the concept of vapor chamber heat spreading to the next dimension with specialized air-cooled heat sinks that incorporate vapor chambers not only in the base, but in the fins as well. Attached to the vapor chamber extensions are high density stamped, zipper, or folded fins, resulting in a 3D vapor chamber heat sink assembly. This compact fin structure paired with fast heat spreading of vapor chambers enable 3D vapor chamber heat sink assemblies to provide isothermal, high-performance air cooled thermal management. These compact, high performance air-cooled heat sinks are designed to meet the most demanding electronics cooling requirements in both commercial and military applications.
Have a Question?
What Are 3D Vapor Chamber Assemblies?
Heat pipes utilize the high heat capacity of fluid phase change in a robust format, making them one of the most efficient and versatile thermal management technologies to reliably and quickly transport heat.
Boyd has two styles of 3D vapor chambers: one with vertical round tube extensions from the main vapor chamber region and one with flat tube extensions. 3D vapor chamber heat sink assemblies are typically configured for 2U to 6U rack heights, but can be designed to fit and perform in your custom application.
How Do 3D Vapor Chamber Assemblies Work?
By extending the vapor space from its traditional 2D format used for heat spreading, a 3D vapor chamber spreads heat into the whole assembly. By promoting isothermal temperatures inside the entire usable volume, 3D vapor chambers enable the maximum thermal performance for air cooled solutions.

3D Vapor Chamber FAQs
What is a 3D vapor chamber?
A 3D vapor chamber is an advanced thermal management solution that spreads and dissipates heat efficiently across three-dimensional surfaces. It uses a sealed structure filled with a working fluid that evaporates and condenses to transfer heat, enabling effective cooling for compact and high-performance devices.
How does a 3D vapor chamber work?
A 3D vapor chamber manages heat through a phase-change process. Heat evaporates the fluid inside which spreads evenly as vapor. The vapor condenses on cooler areas where it dissipates heat from the vapor chamber, and the wick structure moves the fluid back to the heat source. This continuous cycle keeps devices cool and efficient.What is the difference between a 3D vapor chamber and a traditional heat pipe?
A 3D vapor chamber spreads heat across a larger, more complex three-dimensional surface area, making it ideal for compact, high-performance devices. A traditional heat pipe transfers heat along a single axis, focusing on linear applications. The 3D vapor chamber offers more design flexibility and better thermal performance for higher heat load systems.What are the benefits of using a 3D vapor chamber?
A 3D vapor chamber dissipates heat efficiently, enhances device reliability, and supports compact, high-performance designs. It spreads heat evenly across three-dimensional surfaces, reduces thermal hotspots, and offers greater design flexibility for complex systems.Where are 3D vapor chambers commonly used?
3D vapor chambers are commonly used in high-performance electronics like GPUs, CPUs, and gaming consoles, and other high heat load, space-constrained devices. They provide efficient thermal management in applications where compact design and effective heat dissipation are crucial.Are 3D vapor chambers suitable for all types of devices?
3D vapor chambers excel in devices with high thermal loads and space constraints. While they are not required for low-power devices, they provide an optimal thermal solution for high-performance applications. The choice of thermal management solution depends on heat generation, device size, and performance requirements.How long does a 3D vapor chamber last?
A 3D vapor chamber lasts for the lifetime of the device it cools, provided it operates within the specified temperature range and environmental conditions. With proper design and usage, these chambers offer long-term reliability and consistent thermal performance.Can a 3D vapor chamber improve device performance?
A 3D vapor chamber enhances device performance by efficiently managing heat, preventing thermal throttling, and maintaining optimal operating temperatures. This helps improve reliability, extend the lifespan of components, and ensure consistent performance, especially in high-demand applications.Are 3D vapor chambers eco-friendly?
3D vapor chambers are eco-friendly when designed with sustainable materials and manufacturing processes. They enhance energy efficiency by optimizing thermal management, reducing the need for additional cooling systems, and lowering overall energy consumption in devices.Can 3D vapor chambers be repaired or replaced?
Once punctured, 3D vapor chambers cannot be repaired on-site due to their sealed structure. However, they can be replaced during maintenance or upgrades. Proper handling and installation help prevent damage and extend the lifespan of the vapor chamber.Have questions? We’re ready to help!
