Abstract
Electronic equipment comprising a casing provided with lower and upper ventilation openings and with a forced-ventilation fan having an inlet in communication with the inside of the casing and an outlet opening to the outside of the casing. At least one internal partition delimits at least a peripheral chamber and a central chamber toward the top of which the fan is mounted. The openings are arranged to create a natural ventilation flow from the lower openings to the upper openings when the fan is not running and a forced-ventilation flow from the lower openings and the upper openings as far as the fan when the fan is running.

An electronic equipment comprising a box provided with ventilation openings and a forced ventilation blower having an inlet in communication with the inside of the box and an outlet opening to the outside of the box, and means for controlling the blower, the equipment being wherein:
- the box has at least one internal partition defining at least one peripheral chamber and a central chamber having the blower mounted in its top portion;
- at least one external bottom opening is provided in the bottom portion of the box in the central chamber;
- at least one external bottom opening is provided in the bottom portion of the box in the peripheral chamber;
- at least one internal top opening is defined in the top portion of the partition;
- and
- at least one external top opening is arranged in the top portion of the box in the peripheral chamber and/or in the central chamber;
- the openings are arranged to allow a natural ventilation stream from the bottom openings to the external top opening when the blower is stopped, and a forced ventilation stream from the bottom openings and the external top opening to the blower when the blower is in operation, at least one external top opening passing air in two different directions depending on the ventilation stream.
