ABSTRACT:
A deflector shaped in cross-section like an airfoil directs a stream of fluid such as air from a source such as a fan towards a heat-generating component such as a chip to improve cooling of the component. The foil is invented as compared with an airplane wing to produce an inverse "lift" at reduced temperature to cool a heat sink thermally connected to a heat-producing component. The airfoil effect also moves air away from the component at increased velocity to cool it more rapidly. In confined areas multiple deflectors may be arranged in the manner of sails of a boat for augmented cooling.
