Abstract

The ventilation apparatus (20) according to the invention comprises a fan (30) including a rotary machine (32) and a fan wheel (34), an observation module, a module for connecting the device (20) to a power source (12), the fan wheel (34) being set in rotation by the rotary machine (32) when the apparatus (20) is connected to the power source (12), and rotating freely when the apparatus (20) is disconnected from the power source (12). The device (20) further includes an internal power module electrically connected between the rotary machine (32) and the observation module, the internal power module being able to recover an electric current generated by the rotary machine (32) driven by the fan wheel (34), to power the observation module (62), when the apparatus (20) is disconnected from the power source (12).

Dependent claims

A ventilation apparatus comprising:

a fan including a rotary electric machine having a rotary shaft, and a fan wheel secured to the rotary shaft;
an observation module able to generate at least one observation datum relative to the operation of the fan;
a connecting module for connecting the ventilation apparatus to an external power source, the connecting module including a switch making it possible to connect the ventilation apparatus to the external power source in order to power the rotary electric machine and the observation module, and to disconnect the ventilation apparatus from the external power source;
the fan wheel being set in rotation by the rotary electric machine when the ventilation apparatus is connected to the external power source, and rotating freely when the ventilation apparatus is disconnected from the external power source;
the ventilation apparatus further comprising an internal power module electrically connected between the rotary electric machine and the observation module, the internal power module being able to recover an electric current generated by the rotary electric machine driven by the freely rotating fan wheel, to power the observation module, when the ventilation apparatus is disconnected from the external power source, the observation module generating said observation datum relative to the operation of the fan when the ventilation apparatus is connected to the external power source and when the ventilation apparatus is disconnected from it,
wherein the observation module is connected to at least a detector, said detector being able to measure and provide measurements relative to the operation of the fan to the observation module, and
wherein the ventilation apparatus is configured to cool an onboard piece of equipment different from the observation module.
