High energy coaxial cable cooling apparatus
First Claim
1. An electrical insulation tube for providing a plurality of longitudinally disposed channels for guiding fluid flow along the length of an enclosed electrical conductor, comprisinga plurality of elongate insulation strips each having opposing ends,a flat side on each of said elongate insulation strips,an opposing side on each of said elongate insulation strips having at least one open channel extending lengthwise therealong,first and second opposing edges on each of said elongate insulation strips intersecting said flat side and said opposing side, andmating edge means formed on said first and second opposing edges for joining adjacent ones of all of said first and second opposing edges on adjacent ones of said plurality of elongate insulation strips, for forming an insulation tube whereby said plurality of insulation strips when all joined edge to edge form an insulation tube having an inside and an outside wall with said at least one open channel in each insulation strip on said inside wall adjacent to the enclosed electrical conductor.

Abstract
A system is provided for cooling a flexible high energy coaxial cable wherein cooling fluid is circulated along the cable and through a heat exchanger to dissipate the cable heat generated by the high energy transferred by the cable. The cable has inner and outer concentric conductors separated by an inner dielectric layer and surrounded by an outer dielectric layer. Channels in the two dielectric layers provide for the fluid flow along the cable which carries away the heat.
