Patent ID: 7130189

Claim:
An apparatus comprising a portable computer which includes: a housing; circuitry disposed within said housing and having a component; and a temperature adjusting arrangement thermally coupled to said component, said temperature adjusting arrangement including: a thermally conductive section having a side which faces in a direction approximately parallel to an axis, and which is thermally coupled to said component; a plenum having an lower opening and an upper opening, the lower opening being aligned with and having generally the same size and shape as an outer periphery of the thermally conductive section; and a fan that is aligned with the upper opening and having a slightly smaller size than the upper opening in order to move freely therein; wherein the plenum is disposed on a side of said thermally conductive section opposite from said component and operable to direct a fluid flow along said axis toward said thermally conductive section, said thermally conductive section causing said fluid flow to split into a plurality of flow portions which each flow through said thermally conductive section in a direction approximately parallel to a plane perpendicular to said axis.
