Abstract
Abstract In a capacitor in which the electrodes are in the form of elongated conductive sheets separated by elongated dielectric sheets and wound in a compact convolute or roll form with exposed electrodes at each roll edge, heat dissipation is augmented by a chill plate in contact with one of the exposed sheet electrodes at a roll edge and by a plurality of heat pipes connected to the chill plate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
54 words
A capacitor comprising alternate electrode and dielectric strips formed to provide a side of exposed foil edges, a heat conduction block connected to said exposed foil edges, a heat pipe having a heat input section and a heat output section, said heat input section being connected in good heat conductive relationship to said block.
Claim 2
Dependent Claim
54 words
A capacitor comprising alternate electrode and dielectric strips formed to provide a side of exposed foil edges, a heat conduction block connected to said exposed foil edges, a heat pipe having a heat input section and a heat output section, said heat input section being connected in good heat conductive relationship to said block.
Claim 3
Dependent Claim
96 words
A capacitor comprising an alternate array of foil electrodes and dielectric strips wound into a roll to provide an exposed foil edge of one of said electrodes at one end of said roll, a heat conduction means having a pair of opposed faces, one of said faces connected to said exposed foil edge of said roll and oriented generally transverse to the longitudinal axis of said roll, a heat pipe having a heat input section and a heat output section, said heat input section being connected in good heat conductive relationship to said heat conductive means.
Claim 4
Dependent Claim
96 words
A capacitor comprising an alternate array of foil electrodes and dielectric strips wound into a roll to provide an exposed foil edge of one of said electrodes at one end of said roll, a heat conduction means having a pair of opposed faces, one of said faces connected to said exposed foil edge of said roll and oriented generally transverse to the longitudinal axis of said roll, a heat pipe having a heat input section and a heat output section, said heat input section being connected in good heat conductive relationship to said heat conductive means.
Claim 5
Dependent Claim
46 words
The combination of claim 2 in which said heat conductive means is a conductive plate having a pair of opposed faces, one of said faces conductively connected to said exposed foil edge of said roll and oriented generally transverse to the longitudinal axis of said roll.
Claim 6
Dependent Claim
45 words
The combination of claim 3 in which said plate includes a pair of opposed electrically conductive faces and includes an electrically insulating layer interposed between said faces to electrically insulate said opposed faces, said layer being constituted of a material which provides good heat conduction.
Claim 7
Dependent Claim
23 words
The combination of claim 2 in which the height of said roll is less than either the thickness or width of said roll.
Claim 8
Dependent Claim
50 words
The combination of claim 3 in which is provided a plurality of heat pipes, each having a heat input section and a heat output section, each of said heat input sections connected in good heat conductive relationship to said plate and extending from the other opposed face of said plate.
Claim 9
Dependent Claim
75 words
The combination of claim 2 in which said roll provides another exposed foil edge of the other of said electrodes including another heat conduction means connected to said other exposed foil edge and oriented generally transverse to the longitudinal axis of said roll and including another heat pipe having a heat input section and a heat output section, said heat input section being connected in good heat conductive relationship to said other heat conduction means.
Claim 10
Dependent Claim
33 words
The combination of claim 3 in which a thermally conductive and electrically insulating layer of material is interposed between said exposed foil edge of said roll and said one face of said plate.
