Cooling module for an electric or hybrid motor vehicle, having a tangential-flow turbomachine

A cooling module for an electric or hybrid motor vehicle, said cooling module being intended to have an air stream passing through it and comprising:

• a fairing forming an internal duct in a longitudinal direction of the cooling module, the internal duct extending between an upstream end and a downstream end which are opposite to one another and inside which at least one heat exchanger intended to have the air stream passing through it is disposed;
• a collector housing disposed downstream of the fairing in the longitudinal direction, said collector housing including a tangential-flow turbomachine configured to generate the air stream, said tangential-flow turbomachine including a volute which at least partially delimits an outlet for the air stream, the collector housing including, disposed facing the downstream end of the fairing, a guide wall adapted to guide the air stream to the outlet;
• said guide wall including an upstream edge adapted to delimit the outlet for the air stream in a complementary manner to the volute, said guide wall including at least one first opening and at least one first shut-off device which is movable between an opening position and a closure position to respectively open and close said at least one first opening,
• wherein the collector housing includes an additional wall disposed facing the guide wall, the additional wall extending a downstream edge of the outlet, said downstream edge being opposite to the upstream edge of the guide wall, and in that the additional wall comprises includes at least one second opening and at least one second shut-off device which is movable between an opening position and a closure position to respectively open and close said at least one second opening.
