Cooling for One or Two Enclosures
When one or two enclosures are mounted in a rack or cabinet, one
directly above the other, with no other equipment directly below, natural
convection provides sufficient airflow through the enclosures.
directly above the other, with no other equipment directly below, natural
convection provides sufficient airflow through the enclosures.
When one or two enclosures are rack-mounted with other equipment
directly below that produces rising heat, a 9 cm space is required
between the enclosure and the other equipment to exhaust hot air from
below. A deflector must be fitted into this space to avoid mixing the air
flows (Figure 1-5).
