    • A guide vane device for a turbine has an inner platform with a through hole forming a fluid channel for a cooling fluid, wherein the inner platform extends in a circumferential direction around a shaft of the turbine. The guide vane device further includes a hollow aerofoil with a cooling opening for exchanging the cooling fluid passing the through hole into or from the hollow aerofoil, wherein the hollow aerofoil is fixed to a first surface of the inner platform, and a rail with a recess with a cooling fluid passage forming a passage for the cooling fluid to the through hole, wherein the rail is fixed to a second surface of the inner platform and the rail extends along the second surface in the circumferential direction around the shaft. The cooling fluid passage has in the circumferential direction at least the dimension of the through hole.
    • 用于涡轮机的导叶装置具有内平台,其具有通孔,所述通孔形成用于冷却流体的流体通道,其中所述内平台围绕所述涡轮机的轴在圆周方向上延伸。 导向叶片装置还包括具有冷却开口的空心翼面,用于将通过通孔的冷却流体与中空翼型件交换,其中中空翼板固定到内平台的第一表面,以及具有凹槽 其中冷却流体通道形成用于冷却流体到通孔的通道,其中轨道固定到内平台的第二表面,并且轨道沿周向方向围绕轴延伸。 冷却流体通道在圆周方向上至少具有通孔的尺寸。
