Abstract
An electronic module comprises a ventilation device used for the efficient cooling of the components of this module while at the same time minimizing the accumulation of solid particles. To this end, a selector switch is placed between an electrical power supply unit of the module and a motor of the ventilation device. This selector switch cyclically modifies the sense of rotation of the fan in order to suck in an airflow to cool the components and expel the airflow in order to expel the solid particles located in the module and on the ventilation device.
