Compute node cooling with air fed through backplane

摘要

A computing system includes a chassis, one or more backplanes coupled to the chassis. Computing devices are coupled to the one or more backplanes. The one or more backplanes include backplane openings that allow air to pass from one side of the backplane to the other side of the backplane. Air channels are formed by adjacent circuit board assemblies of the computing devices and the one or more backplanes. Channel capping elements at least partially close the air channels.

1. A computing system, comprising:
a chassis; an air inlet end; an air exit end opposite the air inlet end; one or more backplanes coupled to the chassis; a plurality of computing devices coupled to the at least one backplane, wherein at least two of the computing devices comprise a circuit board assembly and one or more processors coupled to the circuit board assembly; one or more air passages adjacent to at least one of the backplanes, wherein at least one of the air passages is configured receive air from the air inlet end of the system; and one or more air channels, wherein at least one of the air channels is configured to channel air between two or more adjacent circuit board assemblies of the computing devices on the at least one backplane, wherein at least one of the air channels is configured channel air toward the air exit end and expel air at the air exit end of the system, wherein the at least one backplane comprises a plurality of openings configured to allow air to pass from at least one of the air passages to at least one of the air channels, wherein at least one of the openings is farther from the air inlet end than at least one other of the openings.
