Abstract
A gas turbine includes a bearing housing surrounding an outside of a tie rod provided on the turbine. One end of a power strut is connected to an outside of the bearing housing, and the other end is radially arranged outwards. A cooling-air supply unit supplies cooling air to the power strut. A heat exchange unit is disposed in the power strut to perform a heat exchange process with cooling air supplied through the cooling-air supply unit. A ring-shaped support frame is connected to the other end of the power strut.
Claims15
A gas turbine comprising:
- a support frame having an annular shape;
- a bearing housing concentrically disposed within the annular shape of the support frame and configured to at least partially surround a tie rod of the turbine;
- a power strut having an interior space in which cooling air flows and further including a first end coupled to an outside of the bearing housing and a second end radially arranged outwardly of the first end and coupled to an inside of the support frame;
- and
- a heat exchange unit formed as a plurality of ribs protruding from an inner wall of the power strut to be disposed in the interior space of the power strut and configured to perform a heat exchange between the inner wall and the cooling air,
- wherein each rib of the plurality of ribs protrudes a variable distance from the inner wall and includes a first end formed at a first radially disposed extreme of the rib and a second end formed at a second radially disposed extreme of the rib opposite the first end, the variable distance increasing gradually from the first end to the second end.
