Vapor Chamber Assemblies
Vapor chamber products are planar and can be used as the base of a heat sink. Aavid’s vapor chamber 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.
Vapor chambers have 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, vapor chamber pass shock and vibration testing, and freeze thaw thermal cycling.
