Abstract
A computing device comprises: a heat sink that has a plurality of cooling fins and a vapor chamber; one or more heat-generating electronic devices that are thermally coupled to the vapor chamber; and at least one cooling fan configured to direct cooling air across the plurality of cooling fins, wherein a first fin included in the plurality of cooling fins and a second fin included in the plurality of cooling fins form a first air passage that has a first air inlet opening and a first air outlet opening, and wherein the first fin is adjacent to the second fin, and a first distance between the first fin and the second fin proximate to the first air inlet opening is less than a second distance between the first fin and the second fin proximate to the first air outlet opening.
