TURBO-MACHINE COMPONENT WITH INTERNAL COOLING Russian patent published in 2020 - IPC F01D5/18 

FIELD: power machine building.

SUBSTANCE: turbomachine component with internal cooling comprises main body (200), which comprises first end wall (210), second end wall spaced from first end wall (210), and side wall (220) extending between first end wall (210) and second end wall so that first end wall (210), second end wall and side wall (220) define cooling channel (230) passing between fluid inlet (202) and fluid outlet (204). Stand group (240) comprises multiple posts (241) covering cooling channel (230) between first end wall (210) and second end wall. At that, group (240) of pillars is spaced from side wall (220) for determination of flow channel (250) between them. Component also comprises flow guide (260) for directing cooling flow from flow channel (250), wherein flow guide (260) extends from flow channel (250) to post group (240). Flow guide (260) has a front edge, a back lump and a central line crossing both the front edge and the trailing edge. Tangent to central line at intersection with front edge forms an angle θ with side wall (220) and / or flow direction (F1, F2) in range from 0 to 45°.

EFFECT: technical result consists in improvement of cooling.
