制造用于内燃机的近壁喷嘴冲击冷却部件的方法

Method of fabricating a nearwall nozzle impingement cooled component for an internal combustion engine
Abstract:
A method of forming an internal combustion engine component having a multi-panel outer wall. The multi-panel outer wall has an inner panel (16) with an inner surface (18) and an outer surface (37). The inner panel outer surface (37) has discrete pockets (23) formed by integral structural ribs (38). Each pocket (23) has a film cooling hole (31) between the pocket (23) and the plenum (20). The method includes: forming dimples (40) in the intermediate panel (22), at least one dimple (40) having a nozzle (29); securing the intermediate panel (22) to the inner panel outer surface (37), thereby enclosing at least one pocket (23); and ensuring a respective dimple (40) having a nozzle (29) protrudes into a respective enclosed pocket (24) and a respective nozzle (29) is configured to direct a respective jet (35) of cooling fluid onto the inner panel outer surface within the respective enclosed pocket (23).
Abstract(Chinese):

一种形成具有多面板外壁的内燃机部件的方法。 多面板外壁具有带有内表面（18）和外表面（37）的内板（16）。 内板外表面（37）具有由整体结构肋（38）形成的分立的袋（23）。 每个袋（23）在袋（23）和集气室（20）之间具有膜冷却孔（31）。 该方法包括：在中间板（22）中形成凹坑（40），至少一个具有喷嘴（29）的凹坑（40）; 将所述中间板（22）固定到所述内板外表面（37）上，从而封闭至少一个凹槽（23）; 并且确保具有喷嘴（29）的相应的凹坑（40）突出到相应的封闭的袋（24）中，并且相应的喷嘴（29）构造成将相应的冷却流体喷射（35）引导到内板的外表面 相应的封闭口袋（23）。
