1. A busbar cooling system for a motor vehicle, the busbar cooling system comprising:
an enclosure with a non-conductive upper housing and a non-conductive lower housing that are configured to permit fluid to flow through the busbar cooling system, the upper housing having an upper internal wall arrangement and the lower housing having a lower internal wall arrangement, wherein the upper and lower internal wall arrangements collectively define a plurality of distinct and concentrically arranged cavities;
a conductive assembly that is configured to permit electrical current to pass through the busbar cooling system, said conductive assembly includes an internal cooling core having a plurality individual conductors that are concentrically arranged in a spaced apart relationship to one another; and
wherein each cavity is configured to receive a substantial extent of one of the conductors of the internal cooling core.
