1. A device for cooling an aircraft propulsion system, comprising:
at least one cooling circuit that has at least one air inlet and at least one air outlet,
at least one intake flap mobile between an open position in which the intake flap uncovers at least partially the air inlet and a closed position in which the intake flap blocks the air inlet, and
at least one exhaust flap mobile between an open position in which the exhaust flap uncovers at least partially the air outlet and a closed position in which the exhaust flap blocks the air outlet,
wherein the cooling device comprises at least one actuator coupled by at least one kinematic system to the pair of intake flaps and exhaust flaps such that said intake and exhaust flaps are driven in synchronized movements and simultaneously occupy the closed position or the open position,
wherein the cooling device comprises a sliding connection configured to connect the intake flap to a structure of the propulsion system and to enable the intake flap to move in translation in a translation direction,
wherein the cooling device comprises a pivoting connection configured to connect the exhaust flap to a structure of the propulsion system and to enable the exhaust flap to pivot about a pivot axis, and
wherein the translation direction and the pivot axis are perpendicular.
