Abstract
Heat dissipating electronic components and circuitry in a communication chassis are cooled by moving air at least through a midplane, between two groups of channels that are perpendicularly oriented relative to one another. In an illustrative embodiment, channels of one group are oriented vertically while channels of another group are oriented horizontally. Each channel, regardless of whether it is vertical or horizontal, is defined by space in the chassis between adjacent circuit boards. Circuit boards on one side of the midplane are electrically connected to circuit boards on the other side of the midplane by orthogonal connectors on the midplane. The midplane additionally has openings that enable movement of air between vertically-oriented channels and horizontally-oriented channels. Circuit boards of the two orientations are cooled by increasing air pressure in vertically-oriented channels or by decreasing air pressure in horizontally-oriented channels or both, depending on the embodiment.
