背景技术
冲击冷却***已被用于涡轮机器(turbinemachinery)以冷却比如为壳体(casing)、叶片、喷嘴等的部件的各种类型的部件。冲击冷却***经由气流冷却这些部件以便在各部件之间保持足够的间隙(clearances)以及提高足够的部件寿命。但是，一些类型的已知冲击冷却***的一个问题在于其趋于需要复杂的铸造和/或结构焊接。这种复杂结构可能不足够耐用和/或其制造和维修非常昂贵。
举例来说，冲击冷却***件(impingementcoolinginsert)可以定位在喷嘴翼型腔内。喷嘴凸缘(nozzleribs)可被加工在腔内用于将冷却***件定位其中。凸缘的端部可能需要被加工成以获得用于将冷却***件焊接或钎焊于其中的适当的交界面。这种过程通常既费时又费钱。此外，零件寿命可能由于穿过接合点的漏气或者其他问题而缩短。
因此希望提供一种改进的涡轮机喷嘴。优选地，这种改进的涡轮机喷嘴可以提供用于将冲击冷却***件快速且有效地***其中，而不会需要昂贵的铸造或机械加工，同时提供足够的冷却以用于延长的部件寿命和提高的整体***效率。

本实用新型还提供一种制造用于燃气涡轮发动机的喷嘴的方法。该方法可以包括以下步骤：浇铸具有腔和带的翼型、围绕腔和带增加具有曲线构造的浮凸部以及相对于浮凸部将密封槽加工到所述带内。
本实用新型还提供一种用于燃气涡轮发动机的喷嘴。该喷嘴可以包括带、在带内加工的密封槽、从带延伸的翼型、位于翼型内的腔、定位在腔内的冲击冷却***件以及围绕所述带和腔浇铸的浮凸部，浮凸部可以具有曲线构造。

基于在结合几个附图和所附权利要求时对以下详细说明的审阅，本领域普通技术人员将变得容易理解本实用新型的这些和其他特征以及改进。
附图说明
图1是燃气涡轮发动机的示意图，示出压缩器、燃烧器、涡轮和负载。
图2是具有冲击冷却***件的喷嘴的透视图。
图3是具有如在本实用新型中所述的冲击冷却***件的涡轮机喷嘴的局部截面图。
具体实施方式
现在参考附图，在附图中，相同的附图标记在全部几个视图中指代相同的元件，图1示出如在本实用新型中使用的燃气涡轮发动机10的示意性视图。燃气涡轮发动机10可以包括压缩器15。压缩器15压缩进入空气流20。压缩器15将压缩的空气流20输送至燃烧器25。燃烧器25使压缩的空气流20与加压的燃料流30混合并且点燃混合物以产生燃烧气体流35。尽管仅示出单个燃烧器25，燃气涡轮发动机10可以包括以环形排列或其他形式定位的任何数量的燃烧器25。燃烧气体流35接着被输送至涡轮机40。燃烧气体流35驱动涡轮机40以便产生机械功。在涡轮机40中产生的机械功经由轴45驱动压缩器15和比如为发电机等的外部负载50。
燃气涡轮发动机10可以利用天然气、液体燃料、各种类型的合成气和/或其他类型的燃料及其混合物。燃气涡轮发动机10可以是由纽约斯克内克塔迪市(Schenectady)的通用电气公司提供的多种不同的燃气涡轮发动机中的任一种，其包括但不限于比如7系列或9系列重型燃气涡轮发动机等。燃气涡轮发动机10可以具有不同的构造并且可以利用其他类型的部件。本实用新型中也可以采用其他类型的燃气涡轮发动机。也可以在本实用新型中同时使用多个燃气涡轮发动机、其他类型的涡轮机以及其他类型的发电设备。
图2示出可以与涡轮机40或类似设备一起使用的喷嘴60的示例。任何数量的喷嘴60可以围绕燃气涡轮机轴以环形排列定位。一般说来，喷嘴60可以包括外带65、内带70以及在其间延伸的一个或更多个翼型75。翼型75可以在其中具有一个或更多个腔80。冷却***件85可以定位在腔80中的一个或更多个中。冷却***件85可以具有穿过其的多个孔，用于经由比如为蒸汽等的冷却介质冲击冷却翼型75的内壁表面。外带65和/或内带70还可以具有形成在其中的一个或更多个密封槽90。密封件可以定位在相邻喷嘴60的密封槽90内，以防止热燃烧气体35由此通过。本实用新型中说明的喷嘴60仅用于举例目的。可以采用许多其他和不同类型的喷嘴构造。
图3示出本实用新型中说明的涡轮机喷嘴100的示例。涡轮机喷嘴100可以包括外带110和内带120(其中仅示出一者)。翼型130可以在外带110与内带120之间延伸。可以采用一个以上的翼型130。翼型130可以具有前缘侧壁140和后缘侧壁150。所述侧壁140、150可以在其间限定翼型腔160。一个或更多个密封槽170可以定位在外带110和内带120中或者围绕外带110和内带120定位，用于使一个或更多个密封件在密封槽之间延伸。涡轮机喷嘴100及其部件可以具有任何适当的尺寸、形状或构造。
涡轮机喷嘴100可以包括定位在翼型腔160内的冷却***件180。冷却***件180可以包括位于其中的多个孔190。在此可以采用任何数量的孔190。冷却***件180和孔190可以具有任何适当的尺寸、形状或构造。冷却***件180的孔190使得冷却介质200能够从孔190通过，以便通过在其上冲击来冷却前缘侧壁140、后缘侧壁150和翼型130的其他表面。冷却介质200可以是蒸汽等等。在此可以采用其他类型的冷却介质。在此可以采用其他部件以及其他构造。
涡轮机喷嘴100还可以包括一个或更多个浮凸部210。浮凸部210可以是适量的另外的翼型材料。浮凸部210可以是浇铸、挤压出(extruded)或其他方式形成其中。浮凸部210可以围绕翼型腔160定位在密封槽170附近。浮凸部210可以具有基本曲线构造220。浮凸部210的曲线构造220可以以大约四十五度(45°)角延伸到翼型腔160内。在此可以采用其他角度以及其他类型的曲线构造。具体地，浮凸部210的圆角和前夹角可以足够大以便获得高质量的可铸性。此外，浮凸部210的长度、高度、尺寸、形状和构造可以变化。可以同时采用具有不同的浮凸部210的喷嘴100。在此可以采用其他部件以及其他构造。
冷却***件180可以接触或不接触浮凸部210。如果接触，浮凸部210可以用作最后时刻的接合支架。具体地，支架可以是用于翼型冷却***件的平台。作为接合支架的使用因此可以在本实用新型中增强总翼型冷却和提高冷却效率。
浮凸部210的使用增大了涡轮机喷嘴100的总体设计空间。具体地，浮凸部210的额外材料使得密封槽170能够在其中加工，而不需考虑穿入到翼型腔160内。密封槽170由此可以具有足够的密封深度，以抵抗密封件拔出和/或密封件破坏。穿入到翼型腔160内可能导致冷却流泄漏以及相关的缩短的零件寿命并且降低的总体性能。此外，更小的总体斜面角度可以用于内带110和外带120上。浮凸部210的利用由此避免了减小的密封槽深度以及增大的斜面角度。
应该明显的是，上述内容仅涉及本实用新型的某些实施例。在不脱离如由下述权利要求及其等同物限定的本实用新型的基本精神和范围的情况下，本领域技术人员可以在此作出多种变化和变型。
