Abstract:
1. An apparatus, comprising: a plurality of line cards, each line card from the plurality of line cards defining an opening and having a surface, a first end portion and a second end portion; and a chassis defining, at least in part, a portion of a first intake flow pathway and a portion of a second intake flow pathway, an interior region of the chassis configured to contain the plurality of line cards such that the opening of each line card from the plurality of line cards collectively defines, at least in part, a portion of an exhaust flow pathway, the chassis configured such that a first gas can flow within the first intake flow pathway between an intake region outside of the chassis and the first end portion of each line card from the plurality of line cards such that a portion of the first gas flows across the surface of each line card from the plurality of line cards in a first direction, the chassis configured such that a second gas can flow within the second intake flow pathway between the intake region outside of the chassis and the second end portion of each line card from the plurality of line cards such that a portion of the second gas flows across the surface of each line card from the plurality of line cards in a second direction, the second direction opposite the first direction, the chassis and the plurality of line cards collectively configured such that a mixture of the first gas and the second gas can flow within the exhaust flow pathway from the interior region of the chassis to an exhaust region outside of the chassis such that a first portion of the mixture of the first gas and the second gas flows in a third direction substantially orthogonal to the first direction and a second portion of the mixture of the first gas and the second gas flows in a fourth direction, the fourth direction opposite the third direction.
