Abstract:
A header () for use with an inner-cooled half coil () in a stator phase winding of an electrical generator. The half coil may include a stack of cooling tubes () with a first stack of conductive strands () adjacent a first side of the stack of cooling tubes and a second stack of conductive strands () adjacent a second side of the stack of cooling tubes. A header () is conductively bonded () by brazing to each strand of the first stack of conductive strands () and to each strand of the second stack of conductive strands () for consolidating the first and second stacks of conductive strands. A means () for allowing a coolant to flow through the header () may be provided to allow coolant to flow through the stack of cooling tubes (). The means () for allowing coolant to flow through the header () may include a plurality of apertures () that are aligned with respective ones of the stack of cooling tubes () for inspecting the cooling tubes through the apertures. Conductive connectors () may be attached to and removed from the header without affecting the consolidation of the conductive strands.
