Vapor Chamber Assemblies: Highest Level of Heat Spreading Performance

Vapor chamber technology gives you better thermal performance and greater reliability compared with traditional heat sinks, thanks to Aavid Thermacore engineering that makes these solutions ideal for extreme temperatures and rugged applications.

Vapor Chamber Assembly (Click to Enlarge)Our dependable Therma-Base® vapor chamber product is a planar, used as the base of a heat sink. Therma-Base delivers higher thermal performance than a traditional heat sink by alleviating spreading resistance found in solid heat sink construction, via three-dimensional spreading, enabling lower device temperature and greater component reliability.

     

copper thermal heat sinkTherma-Base has an enhanced capability to accept higher heat fluxes than a traditional aluminum or copper surface. Its smaller size improves system packaging and provides quieter operation through less air flow. Able to operate in any orientation, the Therma-Base passes shock and vibration testing, and thermal cycling (freeze/thaw).

 

Here's a look at vapor chamber principles in action.

Therma-Base Advantages

  • Highest performing heat spreader in the industry (allows 3D heat spreading)
