A gun barrel structure for a tank having improved heat dissipation properties and accordingly improved accuracy. The gun barrel of the tank is surrounded by a cylindrical heat pipe containing a working fluid. The heat pipe may be constituted by concentric inner and outer cylinders with the working fluid therebetween, or by a single cylinder surrounding the gun barrel with the working fluid held between the outer surface of the gun barrel and the inner surface of the cylinder. Preferably, the heat pipe is divided into a plurality of separate sections disposed along the barrel. A wick holding the working fluid may also be employed.

A tapered gun barrel having a substantially cylindrical shape and having a longitudinal axis, said barrel being surrounded by a cylindrical heat pipe having the same longitudinal axis as said barrel and containing a working fluid, wherein said heat pipe comprises: a first inner peripheral surface of substantially cylindrical shape dimensioned to have a first length measured parallel to said longitudinal axis and extending around substantially the entire circumference of said gun barrel, an outer housing of substantially cylindrical shape dimensioned to have said first length and extending around substantially the entire circumference of said gun barrel and having a second inner peripheral surface and an outer peripheral surface, a longitudinal pair of end sealing means extending radially from said first to said inner peripheral surfaces and connecting said first and second inner peripheral surfaces along said entire first length, a circumferential pair of end sealing means circumferentially connecting said first and second inner peripheral surfaces and defining a closed annular space therebetween, and a wick holding said working fluid and disposed in intimate contact with the first inner peripheral surface and the second inner peripheral surface of said outer housing, at least said outer housing and said first and second end sealing means forming a single continuous C-shaped heat pipe that extends around substantially the entire circumference of said gun barrel such that said longitudinal pair of end sealing means are substantially abutting.
