Method for producing an engine component with a cooling duct arrangement and engine component

摘要

The proposed solution relates in particular to a method for producing an engine component (1) with a cooling channel arrangement (200) which has several cooling channels (2) each with an inflow opening (20, 20.1-20.5, 20a, 20b, 20c), the inflow openings ( 20, 20.1-20.5, 20a, 20b, 20c) are arranged following a predetermined pattern (M1-M5) on an inflow surface (10) of the engine component (1) and each cooling channel (2) is inserted into a recess (3; 3.1-3.5) opens at a wall (11) of the engine component (1), along which a cooling film is to be formed with the cooling fluid guided to the wall (11) via the cooling channel arrangement (200). Provision is made for the pattern (M1) to be built up in at least one sub-area (z1) of the inflow surface (10), which is predetermined in terms of its dimensions, using a large number of identical isosceles triangles (4), which are defined by a minimum distance (k) and one with the minimum distance ( k) correlating mean diameter (a) of the inflow openings (20, 20.1-20.5, 20a, 20b, 20c) are specified.
