19. A heat exchange system for an aircraft turbine engine, the heat exchange system comprising:
a cavity having an air intake;
a heat exchanger arranged in the cavity, the heat exchanger comprising a first circuit through which a first fluid provided by a fluid supply circuit is able to circulate;
a movable flap mounted proximate the air intake and movable between an open position permitting the circulation of the airflow into the cavity towards the heat exchanger and a closed position preventing the circulation of the airflow into the cavity; and
a control device comprising at least one movable member intended to move the movable flap between the open and closed positions, the at least one movable member being distinct from the movable flap,
wherein the control device is arranged in the fluid supply circuit supplying fluid to the heat exchanger,
wherein the control device is configured so as to permit or prevent the circulation of the first fluid towards the heat exchanger and to simultaneously move the movable flap between the open and closed positions, and
wherein the position of the movable flap depends on the position of the movable member.
