Abstract

A ring segment cooling structure with enhanced cooling performance, a ring segment (1600), and a gas turbine (1300) including the same. The ring segment cooling structure includes a cooling channel (1630) and a rib turbulator (1637). The cooling channel is formed inside a shield wall (1611) of a ring segment mounted to a turbine casing that accommodates blades (1400) and is formed in a wavy shape so as to allow cooling air to flow through the cooling channel. The rib turbulator is installed in the wavy-shaped cooling channel.
