Abstract:
1. An internally-cooled fluid directing component comprising: an elongated body member having a first end and a second end; an interior cavity disposed within said body member, said interior cavity having a cooling fluid inlet and a cooling fluid outlet; a partition member disposed within said interior cavity and positioned to divide said interior cavity into a first channel and a second channel; a turning zone disposed within interior cavity and fluidly linking said first and second channels; at least one boundary member disposed within said turning zone, said at least one boundary member dividing said turning zone into a first guided-flow region and a second guided-flow region, with said boundary member being contoured to substantially surround said first guided-flow region; said boundary member including first and second ends with a head portion disposed therebetween, said first and second ends and said head portion being spaced apart from said partition member, with the distance between a free end of said partition member and an upper portion of said head portion being greater than the distance between said first end and said partition member and the distance between said second end and said partition member; wherein said first channel, said turning zone, and second channel cooperatively form a flowthrough path adapted to transmit cooling fluid between said cooling fluid inlet and said cooling fluid outlet, whereby said first and second guided-flow regions are adapted to direct a first portion of cooling fluid through said first guided-flow region and a second portion of cooling fluid through said second guided-flow regions, respectively, thereby allowing strategic cooling of said turning zone.
