Abstract
A heat sink structure is provided having fins mechanically altered dynamically to change and optimize the heat sink's performance based on certain environmental conditions. Specifically, the shape of fins of the heat sink structure is dynamically altered in response to environmental conditions that indicate the need for increased thermal performance by spreading the fins through a mechanical device dynamically, or by collapsing the fins to reduce pressure drop across a region when increased thermal performance is not needed.
