Turbine blade with convective heat exchange function suitable for gas turbine

The invention provides a turbine blade with a convective heat exchange function suitable for a gas turbine, relates to the technical field of turbine blades, and solves the problems that the heat exchange effect of an existing turbine blade is not good, so that heat in the turbine blade cannot be efficiently exchanged or output, and the turbine blade is damaged due to high heat load in long-time application. The turbine blade with the convective heat exchange function suitable for the gas turbine comprises a turbine blade body, wherein a convective heat exchange chamber is formed in the middleof a blade body in the turbine blade body. The airflow in the convective heat exchange chamber rushes through a cut-off opening of a circular rubber sheet sealed in a circular heat dissipation channel under the input of continuous airflow at a circular airflow channel A and a circular airflow channel B, so that the airflow in the convective heat exchange chamber is discharged out of the convective heat exchange chamber f
