    • A turbine nozzle (100) includes an airfoil (400) that extends in span from an inner band (200) to an outer band (300) where the inner band (200) and the outer band (300) define inner and outer flow boundaries of the turbine nozzle (100). At least one of the inner band (200) and the outer band (300) define a first set of cooling channels (214a, 314a) and a second set of cooling channels (214b, 314b) formed beneath a respective gas side surface (218, 318) of the corresponding inner band (200) or outer band (300). The inner band (200) and/or the outer band (300) further define a coolant distribution plenum (216, 316) that is in fluid communication with the first and second sets of cooling channels (214a, 314a). The coolant distribution plenum (216, 316) provides a stream of coolant to at least one of the first set of cooling channels (214a, 314a) and the second set of cooling channels (214b, 314b).
    • 涡轮喷嘴(100)包括从内带(200)到外带(300)的跨度延伸的翼型件(400),其中内带(200)和外带(300)限定内流动边界 的涡轮喷嘴(100)。 内带(200)和外带(300)中的至少一个限定了形成在相应的气体侧表面(218)下方的第一组冷却通道(214a,314a)和第二组冷却通道(214b,314b) ,318)相应的内带(200)或外带(300)。 内带(200)和/或外带(300)还限定与第一组和第二组冷却通道(214a,314a)流体连通的冷却剂分配气室(216,316)。 冷却剂分配室(216,316)向第一组冷却通道(214a,314a)和第二组冷却通道(214b,314b)中的至少一个提供冷却剂流。
