Abstract:
A substantially enclosed cabinet for supporting electronic assemblies to be cooled, the cabinet comprising:a base; a top panel vertically spaced from the base; a first vertical airflow path vertically extending in a direction between the top panel and the base; a second vertical airflow path vertically extending in a direction between the base and the top panel; brackets for supporting electronic assemblies in a vertical array between the first and the second vertical airflow paths; at least one heat exchanger positioned between the base and the brackets for cooling air flowing between the first vertical airflow path and the second vertical airflow path; and at least one substantially planar, vertically extending airflow distribution device having a plurality of apertures in a predetermined pattern of sizes and positions for establishing a predetermined flow rate distribution of cooled air from the second vertical airflow path through electronic assemblies supported on the brackets, wherein the combined area of the apertures of the airflow distribution device decreases in a direction extending between the base and the top panel of the cabinet.
