Airflow management system that can be fitted to an electrical enclosure

Airflow management system that can be fitted to an electrical cabinet which comprises a lower wall, a top wall and at least one lateral bounding an internal volume intended to accommodate electrical devices, the system comprising:

• a casing comprising at least one air input intended to be placed in communication with the internal volume of the electrical cabinet, at least two air outputs, at least one principal throat arranged to connect said at least one air input to the two air outputs, and an input throat connected to the principal throat, the input throat having at least one first end on which there is an axial air input of the at least one air input and a second end connected to a first end of the principal throat at the first end of the principal throat, the input throat running along a lateral wall of the at least one lateral wall of the electrical cabinet,
• a switch device arranged inside said principal throat, between the first air and the second air output, said switch device comprising at least one movable flap that can be controlled between a first position, in which the air input communicates solely with the first air output, and a second position, in which the air input communicates at least with the second air each of the at least two air outputs being arranged to connect to a respective fan of at least two fans, and
• wherein the input throat comprises multiple lateral openings, each lateral opening forming an air input distinct from the axial air input.
