The invention relates to a turbomachine blade comprising a vane. The vane comprises a leading edge, a trailing edge, a pressure face and a suction face spaced apart from each other and connecting the leading edge to the trailing edge. The vane further comprises at least one internal cavity between the pressure face and the suction face, wherein air is intended to flow. The vane comprises intersecting transverse partitions, downstream of the cavity, so that air can flow from the cavity in the direction of the trailing edge between the intersecting partitions.
