Airfoil with thermally conductive pins

A method for producing an airfoil comprising:

• obtaining first and second pieces of a multi-part body, each of the first and second pieces including a respective mating surface and defining multiple respective cavities that extend parallel to one another and are open at the respective mating surface, wherein the second piece defines a network of cooling channels within an interior region of the second piece, and the network of cooling channels is fluidly connected to respective interior ends of at least some of the multiple cavities in the second piece;
• inserting one or more thermally conductive pins into the multiple cavities of the first piece such that each of the one or more thermally conductive pins is received into a different corresponding cavity, wherein each of the one or more thermally conductive pins has a first segment disposed within a corresponding one of the multiple cavities of the first piece and a second segment that projects beyond the mating surface of the first piece;
• and
• coupling the second piece of the multi-part body to the first piece such that the second segment of each of the one or more thermally conductive pins is received into a corresponding cavity of the second piece for aligning the second piece to the first piece.

An airfoil comprising:

• a body having exterior surfaces and an interior region, the body defining multiple cavities and a network of cooling channels within the interior region, the multiple cavities being parallel to one another, the network of cooling channels fluidly connected to respective interior ends of the multiple cavities;
• and
• one or more thermally conductive pins disposed within the multiple cavities such that each of the one or more thermally conductive pins is disposed within a different corresponding cavity of the multiple cavities, each of the one or more thermally conductive pins filling at least a majority of the corresponding cavity without extending into the network of cooling channels,
• wherein a material composition of the one or more thermally conductive pins has a greater thermal conductivity than a material composition of the body.
