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 cast part including a cross-sectional circular area spanning at least a portion of each of four internal passages includes a ratio of interior empty space to inner wall space that improves heat transfer.
