Abstract
A system for cooling a multi-cell power supply, the system including a water pump, a water-to-air heat exchanger in fluid communication with the water pump, and a supply water manifold in fluid connection with the water-to-air-heat exchanger. The system further includes a plurality of power cells in fluid communication with the supply water manifold via one or more water hoses, and a multi-winding device in fluid communication with the plurality of power cells via at least one water-cooled bus, wherein the at least one water cooled bus electrically connects the power cells to secondary windings of the multi-winding device. The water-cooled buses provide both electrical current as well as cooling fluid to each winding of the multi-winding device, thereby eliminating a need for separate cooling and power connections.
