Need Heat Sink Design?

Our seasoned engineer can design heat sink based on customers’ heat dissipation needs, and model and critique the thermal implications of customers’ design using CFD, Solidworks, ProE, and AutoCAD. This enables us to create functional thermal solutions that meet the demanding cooling requirements in the most efficient and cost-effective way possible. We can manage customers’ thermal needs from the conceptual design stage, through prototypes and into production.
