1. A distribution element intended to be fixed to a support structure for supplying cooling fluid to a wall to be cooled facing the distribution element, the distribution element comprising:
a body defining a cooling fluid distribution internal volume;
a multi-perforated plate which delimits the internal volume and comprises a plurality of outlet through-perforations which put said cooling fluid distribution internal volume into communication with the wall to be cooled, and
an inlet orifice opening into the cooling fluid distribution internal volume,
wherein for directing the cooling fluid from the inlet orifice to the plurality of outlet through-perforations the cooling fluid distribution internal volume includes directional fins, and
wherein the directional fins present inclinations and curvatures having a different angle upstream and downstream.
