Turbine blade trailing edge slit cooling structure adopting wavy partition ribs
A technology for turbine blades and cooling structures, which is applied to the supporting elements of blades, engine elements, machines/engines, etc., can solve the problems of reducing the temperature level of the trailing edge area of the blade, and it is difficult to meet the cooling requirements of the trailing edge of the turbine blade. Cooling effect, increased convective heat transfer area, and enhanced heat transfer capacity

Example Embodiment
[0034]Example 1:
[0035]Please refer to Figure 2. A trailing edge split structure of a turbine blade adopting wavy ribs, comprising a hollow turbine blade 1, an inner cavity cold air channel 2, a trailing edge exhaust split channel 3 and a trailing edge split rib 4;
[0036]The hollow turbine blade 1 is provided with an inner cavity cold air channel 2 inside, and a wave-shaped trailing edge exhaust slit 5 is opened along the chord direction at the trailing edge, and a plurality of wave-shaped trailing edge slits are evenly arranged in it The barrier ribs 4 are arranged side by side to form a discrete trailing edge exhaust split channel 3. The channel is in a wave shape with a decay in amplitude and width along the chord direction, and its shape can be controlled by the center line 6 of the top view of the split. Typically, the centerline is designed with 2 crests and troughs in the top view dimension, and its amplitude is AxIs 0.3 times the thickness of the ground leaf shape, the amplitu...
