Abstract
Official abstract text for this publication.
A heat dissipation system that includes a structure having a surface with a cavity recessed on the surface. A wing or channel causes a vortex to occur in the cavity. Destabilizers, such as projections or recesses are disposed on the sidewall of the cavity to disrupt the local surface boundary layer that forms in the cavity. Alternatively, a plurality of freely moving bead elements are disposed in the cavity to disrupt the local surface boundary layer. A cover can be included that prevents the bead elements from exiting the cavity.
First claim
Opening claim text (preview).
What is claimed is: 1. A heat dissipation system configured to dissipate heat using an air flow, the heat dissipation system comprising: a structure having a top surface and having a duct recessed from the top surface for carrying the air flow, the duct having opposed sidewalls and a floor extending between the sidewalls; a plurality of cavities in fluid communication with the duct, each cavity being recessed from the top surface of the structure, the cavity being bounde…
