1. A module of a ventilation device for a cooling module of a motor vehicle, comprising:
at least one tangential turbomachine comprising a bladed wheel and a motor for rotating the bladed wheel;
a frame forming a single opening, wherein the opening faces, in a longitudinal direction of the vehicle, at least part of a heat exchanger of the cooling module; and
shut-off means for selectively shutting off the opening, the shut-off means having at least two regions, which are in contact in a position in which the shut-off means leave the opening clear and are separated in a position in which the opening is shut off,
wherein, when the opening is shut off, air flow passing through the heat exchanger in the longitudinal direction does not bypass the at least one turbomachine.
