Abstract
A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cooling fin includes a ratio of fin height to an average fin thickness that is greater than 2.0 and no more than 18.0. A method is also disclosed.
Claims31
A cast part comprising:
- an outermost wall;
- and
- at least one inner wall defining at least two internal passages;
- and
- at least one cast cooling fin extending from an outer surface, wherein the cooling fin includes a ratio of fin height to an average fin thickness that is greater than 2.0 and no more than 18.0.
2 more elements
A cast part comprising:
- an outermost wall;
- and
- a first inner wall, a second inner wall, and a third inner wall which define at least four internal passages, wherein any cross-sectional circular area spanning at least a portion of each of said four internal passages includes a ratio of interior empty space to inner wall space that is greater than zero and no greater than 3.6.
A method of forming of directionally cast part comprising:
- assembling a core assembly to define an outermost wall, a first inner wall, second inner wall and a third inner wall defining at least four internal passages such that any cross-sectional circular area spanning at least a portion of each of said for internal passages includes a ratio of interior empty space to inner wall space that is greater than zero and no greater than 3.6;
- forming a mold core including the core assembly and a gating portion;
- introducing molten material into the mold core;
- directionally solidifying the molten material;
- and
- removing the core assembly.
