A turbine rotor blade of a gas turbine that includes blades, blades, roots, blades, platforms, and blades. In the leaves, including the impact of regional cooling for blade cooling loop, for the trailing edge of rib column trailing edge cooling and spray cooling loop, for the central region and the serpentine channel leaves at the top of the blade cooling area convective cooling circuit; in the serpentine channel convective cooling loop, near the blade root. At least an elbow region is provided with at least one deflector structure, at least one through hole is arranged with at least one deflector structure of the elbow on the wall; the at least one guide plate structure and the at least one hole of the convective cooling circuit, can effectively to reduce the pressure loss of the cooling circuit, and can effectively enhance the at least one elbow region after strengthening the cooling effect of convective cooling passages in the loop.
