1. An apparatus for guiding air to electronic components comprising:
an intake having a vertically extending cross-section;
a transition portion connected at a first end to the intake and defining a channel having a generally ‘u’ shaped cross-section, an open side of the channel having a first edge and a second edge configured to be positioned substantially opposing a surface, wherein at least the first edge is positioned a distance away from the surface forming a gap between the first edge and the surface, such that air flow is directed towards secondary electronic components; and
a focused egress having a vertically extending cross-section and connected to a second, opposed end of the transition portion such that air flow is directed substantially horizontally towards a primary electronic component;
wherein the gap extends from the intake to the focused egress along a length of the transition portion.
