| 摘要 |
The present invention relates to a component of a flow machine, particularly a turbine blade, which has a cooling channel (9, 10) through which cooling medium can flow, with at least one deflection (5) formed by the wall (11, 12) of the cooling channel, by means of which deflection the flow of the cooling medium from a first channel section (9) is deflected into a second channel section (10) situated downstream. At least one flow guiding element (8) is arranged in the cooling channel in the region of the deflection, and divides the cooling channel into an inner (13) and an outer (14) flow channel. In the present component, the inner flow channel (13) has a constriction in the flow cross section. By the proposed configuration of the cooling channel deflection, the pressure loss brought about by the deflection is minimized and simultaneously a distinctly more homogeneous heat transfer is attained to the cooling medium, without local temperature peaks.
