Cooling structure of top contra-rotating vortex of high temperature turbine moving blade

The invention discloses a cooling structure of a top contra-rotating vortex of a high temperature turbine moving blade, and belongs to the field of turbine heat transmission. The cooling structure of the top contra-rotating vortex of the high temperature turbine moving blade comprises a turbine tenon, a turbine blade body, a turbine blade front edge, a turbine blade top cover, a turbine blade tail edge, a serpentine channel and a contra-rotating vortex generator; the turbine tenon is connected with the tail of the turbine blade body into a whole; the top of the turbine blade body is closed through the turbine blade top cover; a cold air hole is formed in the turbine blade top cover; the serpentine channel is formed in the turbine blade body and is located at the chord-length middle part of a turbine blade; an air outlet channel of the serpentine channel communicates with the cold air hole; and the contra-rotating vortex generator is fixedly arranged on the internal surface of the turbine blade top cover and corresponds to the serpentine channel. The cooling structure is used for cooling the high temperature turbine moving blade, and has the characteristics that heat transfer is enhanced through forming the contra-rotating vortex and increasing a heat transfer area, and the increasing of the flow resistance is inhibited effectively.
