Components having channels for impingement cooling

A rotary machine comprising:

• a combustor section configured to generate combustion gases;
• a turbine section configured to receive the combustion gases from said combustor section and produce mechanical rotational energy therefrom, wherein a path of the combustion gases through said rotary machine defines a hot gas path;
• and
• a component proximate said hot gas path, said component comprising:
• an inner wall defining a plurality of apertures, each aperture of said plurality of apertures configured to emit a cooling fluid therethrough;
• an outer wall spaced from said inner wall and extending from a root end to a tip end of said component, wherein said outer wall and said inner wall extend along a longitudinal axis extending from said root end to said tip end of said component, wherein said inner wall further defines a first surface and said outer wall defines a second surface opposite the first surface;
• and
• a plurality of angled walls extending between said first surface and said second surface, said plurality of angled walls defining a plurality of angled channels in fluid communication with said plurality of apertures, wherein each angled wall of said plurality of angled walls extends at an acute angle relative to the longitudinal axis.
