Beschreibung
Zusammenfassung:	A cooled turbine blade (440) is disclosed herein. The cooled turbine blade has a base (442) including a cooling air inlet (481) and a channel (483), and an airfoil (441) including a multi-bend heat exchange path (470) starting at the base and ending at a cooling air outlet (471) at a trailing edge (447) of the airfoil. The airfoil also includes a skin (460) surrounding the tip wall (461) and the inner spar (462). 本文公开了一种冷却涡轮叶片(440)。所述冷却涡轮叶片具有基部(442)和翼型件(441)，所述基部包括冷却空气入口(481)和通道(483)，所述翼型件包括在所述基部处开始且在所述翼型件的后缘(447)处的冷却空气出口(471)处结束的多弯曲热交换路径(470)。所述翼型件还包括表皮(460)，所述表皮包围尖端壁(461)和内翼梁(462)。
