Abstract: An annular wall for a turbomachine combustion chamber is disclosed, comprising cooling orifices through which cooling air can circulate through the annular wall, each having an air injection axis oriented orthogonal to a longitudinal axis of the annular wall. The cooling orifices are distributed into first annular rows of cooling orifices oriented in a first circumferential direction from an outer face as far as an inner face of the annular wall, and second annular rows of cooling orifices oriented in a second circumferential direction opposite the first circumferential direction from the outer face as far as the inner face of said annular wall. The first annular rows and the second annular rows of cooling orifices are arranged alternately along the longitudinal axis.
