Capacitor energy storage improvement by means of heat pipe

Claim 1

A capacitor comprising in combinAtion: a first heat pipe consisting of an evacuated metal tube having its inner surfaces provided with a wick partially saturated with a volatile liquid; a second heat pipe comprising a centrally perforated evacuated hollow metal disc member having the inner surfaces thereof provided with a wick saturated with a volatile liquid and affixed in electrical and thermal conductivity coaxially with said first heat pipe adjacent one end thereof; a third heat pipe comprising a centrally perforated, evacuated hollow disc member having a tubular electrical insulator affixed in said perforation and having its inner surfaces provided with a wick partially saturated with a volatile liquid, and affixed in electrical insulation and thermal conductivity coaxially with said first heat pipe adjacent the end thereof opposite said one end; a convolutely wound extended foil capacitance section positioned around said first heat pipe between said second and third heat pipes comprising an outer (first) foil and an inner foil spaced by electrical insulation; said outer foil having its extended edge soldered to a inwardly directed plane surface of said second heat pipe whereby the section of said first heat pipe extending from said third heat pipe to said end thereof opposite said one end forms one terminal of said capacitor; said inner (second) foil having its extended edge soldered to a inwardly directed plane surface of said third heat pipe; a metal collar coaxial with said fist heat pipe affixed to an outwardly directed plane surface of said third heat pipe along the section thereof contiguous with said end opposite said one end and forming another terminal of said capacitor; and an electrical insulating shell extending between said inwardly directed plane surfaces and encompassing said capacitance section.
