A layout for cooling a blade having a cavity surrounded by an internal wall including cooling fins which are spaced apart from each other by a pitch (p) and each have a thickness (e). The blade has, inside the cavity, a jacket passed through by emission holes each having a diameter (d). When the jacket is in place in the cavity of the blade, and in respect of the critical operating point of the turbine engine, each emission hole of the jacket is opposite a place on the internal wall of the blade which is located between cooling fins.
