    摘要： A turbine engine component (100) includes a wall (150) extending from a leading edge (170) to a trailing edge (180). The wall (150) includes a hot side surface (211) facing a gaspath when the component (100) is in an installed state, and a cold side surface (212) opposite the hot side surface (211). At least one minicore cooling circuit (290) is disposed between the hot side surface (211) and the cold side surface (212) within the wall (150). At least one cooling fluid inlet (214) connects the minicore cooling circuit (290) to a coolant source (213). At least one film cooling hole (217) connects the minicore cooling circuit (290) to the hot side surface (211). The minicore cooling circuit (290) includes an edge plenum (216) having a thickness (220) normal to the hot side surface (211) that is larger than a thickness (221) of the majority of the minicore cooling circuit (290) normal to the hot side surface (211). The edge plenum (216) is a portion of the at least one minicore cooling circuit (290) most proximate to one of the leading edge (170) and the trailing edge (180).
