Techniques for cooling electronics assemblies are provided. A divider, such as an electronic card, is utilized to define flow channels through the chassis of the electronics assembly. The divider is parallel to the electronic cards and air movers, such as fans, can be utilized in a push-pull configuration to cause air to flow and counter-flow through the flow channels to cool the electronic cards.

What is claimed is: 1. An electronics assembly, comprising: a chassis defining an internal cavity for receiving a plurality of electronic cards; a divider within the chassis, the divider being parallel to the electronic cards and defining at least first and second flow channels, wherein the divider is one of said plurality of electronic cards; a first air mover configured to cause air to flow through the first flow channel; and a second air mover configured to cause air flowing in the first flow channel to flow through the second flow channel. 2. The electronics assembly of claim 1, wherein the first and second air movers are fans or blowers. 3. The electronics assembly of claim 1, further comprising a flow guide to assist air flow from the first flow channel to the second flow channel. 4. The electronics assembly of claim 1, wherein the first and second air movers are in a fan tray. 5. The electronics assembly of claim 1, wherein the first air mover is in a fan tray with one or more additional air movers. 6. The electronics assembly of claim 1, wherein the second air mover is in a fan tray with one or more additional air movers. 7. The electronics assembly of claim 1, wherein the air flowing in the first channel flows in direction opposite the air flowing in the second flow channel. 8. The electronics assembly of claim 1, further comprising an intake opening for air to flow through to the first flow channel. 9. The electronics assembly of claim 1, further comprising an exhaust opening for air to flow through from the second flow channel. 10. An electronics assembly, comprising: a chassis defining an internal cavity for receiving a plurality of electronic cards; an electronic card means for defining first and second flow channels within the chassis, the means for defining being parallel to the electronic cards and; a first means for moving air through the first flow channel; and a second means for moving air in the first channel to flow through the second flow channel.
