Problems solved by technology

The disadvantage here is that a significant amount of purge air is required to keep the temperature of the mixed hot gas low
Significantly increased quantity of purge air is required especially in the case of larger gaps
This type of cooling loses its effect if the gap width changes during operation in a way that does not correspond to the desired purge air volume

Embodiment Construction

[0032] According to the invention, the technique of sinking cooling channels close to the surface is used for cooling corners or edges of gas turbine components (for example rotor blades, guide vanes or heat shields) which are subjected to high thermal loads. in accordance with figure 2 The problem with the configuration of is that the edge 22 is exposed to hot air from two surfaces that abut one another and is thus subjected to a very high thermal load in the corner region 24 .

[0033] according to image 3 Cooling channels 25 with a small inner diameter running parallel to the edge 22 are now provided directly below the surface in the edge region in order to cool the corner effectively and with reduced use of coolant (usually cooling air) Area 24. The inlet 30 and outlet 29 of the cooling channel 25 are in image 3 shown in dotted line.

[0034] The cooling channel 25 (with the inlet 30 ) starts from a plenum filled with cooling air, then runs parallel to the edge 22 t...

Abstract

The invention relates to a component for a thermal machine, in particular a gas turbine, said component having a corner and / or edge (22) subjected to a thermally high load. The cooling of the component is improved in a manner such that at least one cooling channel (25) is countersunk into the surface of the component in the immediate vicinity of the corner and / or edge (22) in order to cool the corner and / or edge (22).

Description

technical field [0001] The invention relates to the field of heat engines. The invention relates to a component for a heat engine, in particular a gas turbine, according to the preamble of claim 1 . Background technique [0002] In heat engines, in particular gas turbines, there are various components which on the one hand have corners and edges for structural reasons and on the other hand are exposed to high thermal loads at these points during operation. An example of such a component is a multi-part rotor blade of a gas turbine, as disclosed, for example, in publication EP 2 189 626 A1. of the published document figure 1 and 2 In this application as figure 1 was recounted. [0003] exist figure 1 The components shown in , namely the platform element (Platform-Element) 10 and the blade element (Shaufelblatt-Element) (Shaufelblatt-Element) 20 , are assembled to form a rotor blade and are connected to each other. The platform element 10 has in the upper side 11 a thro...
