A direct air cooling system 12 for electronics carried by aircraft. The cooling system provides a submerged air scoop 16 which directs outside air to several electronic modules 14. The air flows through passages 76 in the modules 14 which are adjacent to circuit boards 74, 78 bearing discrete electronic components 88. A foil layer 86 and aluminum fin stock help transfer heat from the electronic components to the directed air. Heated air is then exhausted through exhaust port 24 or 28.

A direct air cooling system for aircraft electronics which comprises: (a) a submerged air scoop for bringing an air flow from the exterior of an aircraft to its interior wherein said air scoop comprises a vacuum slot for drawing off boundary layer air from the air flow passing through said air scoop

A direct air cooling system for aircraft electronics which comprises: (a) a submerged air scoop for bringing an air flow from the exterior of an aircraft to its interior wherein said air scoop comprises a vacuum slot for drawing off boundary layer air from the air flow passing through said air scoop in order to avoid air flow separation and stagnation, (b) an inlet air duct for directing said air flow to electronic modules requiring cooling wherein said electronic modules comprise a multitude of electronic circuit board assemblies comprising circuit boards, discrete heat producing electronic components, a heat spreader and air passages adjacent to said circuit boards wherein said air passages are connected to said air inlet duct and comprise theremally conductive fin stock positioned to produce a high capacity heat transfer area where air from said inlet duct is used to cool said circuit boards and discrete heat producing components via said heat spreader; and (c) an air exit port duct connected to said air passages for exhausting air to an exhaust port on the exterior of said aircraft.
