Abstract
An enclosure that includes at least first and second pieces of equipment having separate cooling airflows. A baffle is disposed within the enclosure to separate the enclosure into two compartments and to isolate the airflows for each piece of equipment within each of the respective compartments. The baffle includes a step portion to provide for a smooth airflow and to prevent hot spots from being formed on the baffle. The heated airflow from the second compartment is redirected away from the first compartment to an air duct or chimney that transports the heated air from the second compartment to an air output vent. When acting as a chimney, the air duct includes a flue portion, a buffer portion to enhance the convection draft, and an output opening. The separate airflows may be either convection driven or be a forced airflow driven by one or more fans.
