An improved electronic communications system and process 100 with front to back cooling can be provided in which the flow of influent cooling air can be directed horizontally through an intake cooling plenum chamber 145-146 positioned above or below line cards 127-129 and then passed downwardly through an inlet side cooling plenum 139-141. The cooling air can thereafter be propelled sideways, laterally and horizontally across passageways 138 between the line cards to remove heat generated by the line cards. The effluent heated air can be passed upwardly through an outlet side cooling plenum 142-144 and can be discharged through an exhaust cooling plenum to chamber 147-148 which can be diagonally separated from the intake cooling plenum chamber 145-146 by a fluid-impermeable plate 149-151. |
