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.

Abstract: A power delivery system includes a group of removable power cells. Each power cell includes a water cooled heat sink, an air intake, and an air output. The system also includes a heat exchanger. The heat exchanger draws air from the cells, cools it, and recirculates the cooled air to the cells via each cell's air intake. The cell may be designed so that components that are not near the heat sink are cooled by air from the intake before that air reaches the heat sink.

Abstract: A method of operating a power delivery system that has at least one power cell includes directing air into the power cells to cool them, receiving the air from the cells, directing the air to a cooling system, and recirculating the cooled air to the power cells. Each cell may include an air intake, an air output, a water-cooled heat sink, and optionally a plurality of capacitor connectors and/or a circuit board. The air may be directed through the air intake to the air output so that air passes over the capacitor connectors and/or the circuit board before passing over the heat sink.
