Patent ID: 8708647

Claim:
A liner for a turbine section, the liner comprising a first wall, a plurality of webs interconnected with and projecting from the first wall, and a plurality of A liner for a turbine section, the liner comprising a first wall, a plurality of webs interconnected with and projecting from the first wall, and a plurality of cooling channels for air cooling of the liner, each of the cooling channels being delimited by two adjacent webs and the first wall, wherein the material of the webs has a higher thermal conductivity than the material of the first wall, an exterior surface of the liner for facing the turbine section to be lined being continuous and uninterrupted, each of the cooling channels being delimited by two adjacent webs and the first wall, wherein each cooling, channel presents a height corresponding to the height of its delimiting webs, and a width corresponding to the distance between its delimiting webs, wherein at least one of the cooling channels has a width/height ratio of below 5, wherein the material of the webs has a higher thermal conductivity than the material of the first wall, and an exterior surface of the liner for facing the turbine section to be lined is continuous and uninterrupted.
