FIELD: oil, gas and coke-chemical industry.
SUBSTANCE: invention relates to a device for cooling component (1) of a gas turbine/turbomachine, comprising external surface (2) exposed to hot gas, and integrated cooling channel (3), wherein inside cooling channel (3) injection cooling element (4) is located with at least one injection cooling hole (5), wherein the injection cooling element (4) is located at a distance from target surface (6) of component (1) to be cooled, and for cooling component (1), the cooling fluid in the form of an injection cooling jet is capable of passing to target surface (6), on which there is surface structure (8) exposed to injection cooling jet. Surface structure (8) is formed by ribs (9), diverging beams in the form of a star, and protruding from target surface (6).
EFFECT: higher efficiency of cooling.
