Claim of US Patent No. 10,117,358

1. An electronic equipment chassis assembly comprising:a housing having a top surface, a bottom surface opposite the top surface, a front surface, and a rear surface opposite the front surface, the front surface and the rear surface separating the top surface and the bottom surface;
a plurality of openings defined in the housing that allow airflow there-through, the openings include at least one intake opening defined in a bottom portion of the front surface of the housing and a plurality of exit openings defined in the rear surface of the housing;
a mid-plane located proximate an interior perimeter of the housing;
one or more rails disposed within the housing defining receiving slots that releasably secure a first plurality of circuit boards and a second plurality of circuit boards in parallel configurations, respectively, and releasably secure the second plurality of circuit boards in an orthogonal orientation relative to the first plurality of circuit boards, wherein the second plurality of circuit boards are directly coupled to the first plurality of circuit boards by orthogonal connectors, the coupling being independent of the mid-plane;
an airflow assembly positioned in the top surface of the housing, at least a portion of which is dispose above the one or more rails, the airflow assembly facilitates airflow through the plurality of openings defined in the housing, and between each of the first plurality of circuit boards secured in the one or more rails, and through the at least one exit opening wherein the airflow assembly includes at least one fan and at least one blower configured to create a pressure differential between an outside and inside portion of the housing to facilitate a first flow of air from the at least one intake opening that is redirected a first time between each of the first plurality of circuit boards and is redirected a second time via the at least one exit opening to exit the housing; and
one or more output fans proximate the rear surface of the housing, wherein the one or more output fans redirect at least a portion of the first flow of air, after it is redirected the first time between each circuit board of the second plurality of circuit boards and through the at least one exit opening.
