Baffles for high capacity air-cooling systems for electronics apparatus

An intake baffle comprising:

• a platform comprising an opening to be juxtaposed to a fan intake;
• and
• a box-like plenum coupled to the platform and having a pair of sides, a back wall, and a top,
• wherein the platform includes a ramp angled towards and forming an arc about one side of the fan intake,
• wherein the plenum has a cross-sectional area that increases with distance from the fan, and
• wherein the plenum and the ramp are to direct air into the fan intake.
