Abstract
A cooling structure for a radial turbine is equipped with a partition wall arranged between a compressor and the radial turbine, and a through hole formed in the partition wall supplying a part of air compressed by the compressor to the rear surface of the radial turbine as cooling air. The through hole is inclined in a rotational direction of the radial turbine in the range of 40° to 80° with respect to a rotation axis of the radial turbine.
Claims6
A cooling structure for a radial turbine in a rotating machine, the rotating machine including a compressor configured to compress air and the radial turbine rotationally driven by combustion gas, the cooling structure comprising:
- a partition wall disposed between the compressor and the radial turbine and separating a region where the compressor is disposed and a region where the radial turbine is disposed;
- and
- a through hole provided in the partition wall and through which a part of the air compressed by the compressor is supplied to a rear surface of the radial turbine as a cooling air,
- wherein the through hole is inclined in a rotational direction of the radial turbine in a range of 40° to 80° with respect to a rotation axis of the radial turbine.
