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. |
