To provide a cooled structure of a gas turbine.SOLUTION: A cooled structure has a leading edge, a trailing edge, a first side portion orthogonal to each of the leading and trailing edges, and a second side portion opposite to the first side portion and substantially orthogonal to each of the leading and trailing edges. The cooled structure includes a substrate surface defined by boundaries including the leading edge, trailing edge, first side and second side portions. A first set of cooling channels beneath the substrate surface extends from a first set of inlets proximate to the first side portion to a first set of exits proximate to the second side portion. A second set of cooling channels beneath the substrate surface extends from a second set of inlets proximate to the second side portion to a second set of exits proximate to the first side portion. Each first inlet overlaps with an exit of the second set of exits.SELECTED DRAWING: Figure 5 【課題】ガスタービンの被冷却構造を提供する。【解決手段】被冷却構造は、前縁と、後縁と、前縁および後縁の各々に直交する第１の側部と、第１の側部の反対側であり、前縁および後縁の各々に実質的に直交する第２の側部とを有する。被冷却構造は、前縁、後縁、第１の側部および第２の側部を含む境界によって画定された基板表面を含む。基板表面下の第１の組の冷却チャネルは、第１の側部に近接する第１の組の入口から第２の側部に近接する第１の組の出口に延びる。基板表面下の第２の組の冷却チャネルは、第２の側部に近接する第２の組の入口から第１の側部に近接する第２の組の出口に延びる。各第１の入口は、第２の組の出口の１つの出口と重なり合う。【選択図】図５
