Abstract
A circuit card assembly includes a circuit card, a plurality of components disposed on a first surface of the circuit card in a shadow arrangement, and a plurality of air-cooled heat sink structures disposed on each of the components. Each of the plurality of heat sink structures comprises a plurality of impedance zones arranged in series substantially perpendicular to the airflow path, where the plurality of impedance zones comprise a first impedance zone having a first air impedance, and a second impedance zone having a second air impedance less than the first air impedance. Further, the plurality of zones in the plurality of heat sink structures are aligned so that the first impedance zone in one of the plurality of heat sink structures does not overlap with the first impedance zone in another of the plurality of heat sink structures, relative to the airflow path.
