1. A fluid-cooled housing for an electric device, comprising:
- an outer surface and an inner surface, the inner surface defining, at least in part, a housing cavity having a longitudinal axis;
an end wall continuous with the inner surface, thereby substantially enclosing the housing cavity at a first end thereof, the inner surface having a plurality of core print openings along the longitudinal axis; and
a helical channel formed by casting within the housing between the outer and inner surfaces along the axis, the helical channel formed from a helical coil core made of compacted sand and having two or more laterally extending tabs which form the core print openings, the helical coil core being positioned between cope and drag molds prior to casting, the helical channel being formed by material forming the housing without any separate conduit material being used.

Abstract
The present disclosure is directed to a fluid-cooled housing for an electric device having an outer surface and an inner surface, the inner surface defining, at least in part, a housing cavity having a longitudinal axis, an end wall continuous with the inner surface. The inner surface having a plurality of core print openings along the longitudinal axis, and a helical conduit integrated within the housing between the outer and inner surfaces along the axis formed from a helical coil core having two or more laterally extending tabs which form the core print in two or more planes.
