Electronics cooling system and corresponding devices and methods

An electronics cooling system, comprising:

• a housing comprising a front face, a rear face, and one or more sidewalls, the housing defining four quadrants arranged in a clockwise order, the front face defining an air inlet in a first quadrant, the rear face defining an air exhaust in a third quadrant;
• a first plenum disposed adjacent to the air inlet;
• a second plenum disposed adjacent to the air exhaust;
• and
• one or more circuit card corridors disposed between the first plenum and the second plenum;
• wherein the first plenum is defined by a volume having an L-shape;
• and
• one or more fan modules disposed between the first plenum and the one or more circuit card corridors, the one or more fan modules operable to draw air in a direction parallel to the front face and the rear face, the one or more fan modules comprising a first fan module having a first plurality of fans coupled to a first carrier and a second fan module having a second plurality of fans coupled to a second carrier.

An electronics cooling system, comprising:

• a housing comprising a front face and a rear face, the housing defining four quadrants, the front face defining an air intake in a first quadrant, the rear face defining an air exhaust in a second quadrant 180-degrees out of phase from the first quadrant;
• a first plenum inside the housing adjacent to the air intake;
• a second plenum inside the housing adjacent to the air exhaust;
• one or more circuit card corridors disposed between the first plenum and the second plenum;
• a first fan module, adjacent to and oriented orthogonally with the front face, and operable to redirect air entering the air intake from a first direction to a second direction;
• and a second fan module, adjacent to and oriented orthogonally with the rear face, and operable to redirect air entering the air intake from the first direction to the second direction, the first fan module having a first plurality of fans coupled to a first carrier and the second fan module having a second plurality of fans coupled to a second carrier.
