Abstract: A fluid cooled electrical capacitor assembly (10) includes a stack of honeycomb sheet-like structures (12) of dielectric material with an electrode (16) between each pair of honeycomb sheet-like structures. Alternate electrodes are electrically coupled together to each other and may be coupled to respective terminals of an electrical circuit. Fluid passages (20) in the honeycomb sheet-like structures provide a place for fluid (20a) to affect electrical characteristics of the capacitor assembly and/or to provide for cooling while preventing the fluid from contacting the electrodes. A method of assembling a capacitor assembly includes placing capacitor subunits including a dielectric honeycomb sheet-like structure and an electrode in parallel planar, overlying relation with the honeycomb. A method of cooling a capacitor assembly of dielectric honeycomb structure and electrodes includes directing a fluid through flow channels in the honeycomb structure.

Abstract: A method of using honeycomb material having opposite surfaces and flow channels between the surfaces, includes directing fluid flow through the channels while applying a voltage between the surfaces and across fluid flowing in the channels. A method of using honeycomb material that includes at least one electrode, the honeycomb material and electrode be useful in an electrical or electronic device, includes using the honeycomb material to support or to suspend the electrical or electronic device. An apparatus includes a honeycomb structure of dielectric material having a number of flow channels therethrough, an electrode at a surface of the dielectric material responsive to electrical input to apply an electrical response alone or with regard to another electrode, the honeycomb structure having cohesive strength and rigidity to support itself and the electrode from in suspended relation.
