PROBLEM TO BE SOLVED: To provide a hot gas path component cooling system having a particle collection chamber.SOLUTION: A cooling system for a hot gas path component includes a substrate 78 having an outer surface 80 and an inner surface. The inner surface defines at least one interior space. A passage is formed in the substrate 78 between the outer surface 80 and the inner surface. An access passage is formed in the substrate 78 and extends from the outer surface 80 to the at least one interior space. The access passage 94 is formed at a first acute angle to the passage and includes a particle collection chamber 98. The access passage 94 is configured to channel a cooling fluid to the passage 76. Furthermore, the passage 76 is configured to channel the cooling fluid therethrough to cool the substrate 78.SELECTED DRAWING: Figure 6 【課題】粒子収集チャンバを有する高温ガス経路構成要素冷却システムを提供すること。【解決手段】高温ガス経路構成要素用の冷却システムは、外面８０及び内面を備える基材７８を含む。内面は、少なくとも１つの内部空間を定める。通路は、基材７８の外面８０と内面との間に形成される。アクセス通路は、基材７８に形成され、外面８０から少なくとも１つの内部空間まで延びる。アクセス通路９４は、通路に対して第１の鋭角で形成されて粒子収集チャンバ９８を含む。アクセス通路９４は、冷却流体を通路７６に送るように構成される。さらに、通路７６は、その内部を通して冷却流体を送り、基材７８を冷却するように構成される。【選択図】図６
