Apparatus for uniforming heat of gun barrel

An apparatus for the uniform heating of a gun barrel having an outside peripheral surface, comprising:

• first and second spaced arcuate members having aligned edges, said members being disposed substantially parallel to each other to form, respectively, inner and outer arcuate walls for substantially encircling the gun barrel, said first and second members each having opposing parallel edges extending longitudinaly along the gun barrel with the first member being in intimate contact with the outside peripheral surface of the gun barrel, said arcuate members being sealed at the edges thereof forming a chamber therebetween;
• a liquid substantially filling the chamber;
• a wick disposed in the chamber for providing capillary circulation for the liquid;
• a heat insulating cover in intimate contact with the entire second arcuate member, the heat insulating cover substantially encircling the gun barrel;
• said liquid uniformly dissipating heat generated from the interior of the gun barrel and the interior of the heat insulating cover;
• and
• said heat insulating cover being operative to shade the second arcuate member from solar radiation.
