AXIALLY ALIGNED ELECTRONIC CHASSIS

摘要

A technique for housing printed circuit board assemblies (PCAs) includes providing a set of backplane or midplane boards that are oriented orthogonally and edge-to-edge with an array of PCAs such that air introduced at one end of the chassis passes in a straight line course through the PCAs and through the backplane or midplane boards with no substantial bends or changes in direction.

主权项

1. A chassis for housing printed circuit board assemblies (PCAs), comprising:
first and second contiguous regions, the first region housing a first array of one or more PCAs oriented parallel to a Y-Z plane of a mutually orthogonal X-Y-space, the second region housing a second array of one or more PCAs oriented parallel to an X-Z plane of the X-Y-Z space, the second array of PCAs having connectors for connecting directly with connectors on the first array of PCAs; and an airflow path established within the chassis for conveying air in a straight line course along a Z direction of the X-Y-Z space through the first array of PCAs and through the second array of PCAs.
