Abstract (en)
The present invention provides a stator heat shield (10) for a gas turbine, the gas turbine having a rotor defining an axis of rotation, the stator heat shield comprising a plurality of cooling units (20) disposed in array along the axis of rotation, each of the cooling units comprises an outside part (21) facing hot gas path of the gas turbine, and an inside plate (22) positioned on the outside part and exposed to cooling air, wherein the inside plate comprises a plurality of inlet openings (23) formed through the inside plate to introduce the cooling air into the outside part and thereby impingement cooling of the hot gas washed wall of the outside part , the outside part comprises a cooling air channel (24) formed therein with a first central portion (25) to receive the cooling air, and a second spiral portion (26) around the first central portion to convey the cooling air outward to a cooling air outlet of the second spiral portion.
