ELECTRONIC RACK HAVING NATURAL CONVECTION AND CIRCULATION OF FORCED AIR FOR COOLING IT

摘要

This rack (1) houses rackable modules (2, 3) of electronic equipment and has a natural convection cooling system thanks to ventilation holes (20, 21) made in its lower (10) and upper (11) walls and a forced-air cooling system thanks to internal air delivery rails (30) fed with pressurized air by means of a distribution box (31) connected to a forced-air circulation line (37). By using internal delivery rails for the forced air it is possible for the circulation of drawn air to be only a slight obstacle to the air circulation obtained by natural convection. Compared with standard configurations, this makes it possible to lower the operating temperature reached by the equipment in the event of a loss of forced ventilation.
