US12618629 - System for cooling automatic firearms and cannons
The patent describes a barrel cooling system for firearms that incorporates a corrosion prevention cylinder situated between the barrel and cooling fins, enhancing heat dissipation while preventing corrosion. This system features multiple layers of corrosion-prevention materials and inserts designed to maintain the integrity of the weapon barrel during high-rate firing.
Claim 1
1 . A corrosion prevention cooling system for a barrel of a weapon, comprising: a plurality of cooling fins; a weapon barrel; a cylinder having at least a first layer of corrosion-prevention material and a second layer of a different corrosion-prevention material, the cylinder interposed between the weapon barrel and the cooling fins; and a plurality of corrosion-prevention inserts interspersed throughout at least one of the first layer and the second layer, the plurality of corrosion-prevention inserts being orthogonal to (i) at least one of the first layer and the second layer, and (ii) the weapon barrel, wherein: an inner surface of the first layer abuts an outer surface of the weapon barrel; and an outer surface of the second layer abuts an inner surface of the plurality of cooling fins; wherein, when ammunition is fired through the weapon barrel at a high rate, the first layer, the second layer, and the corrosion-prevention inserts permit the cooling fins to dissipate heat away from the weapon barrel while simultaneously protecting the weapon barrel from corrosively reacting with the cooling fins. a plurality of cooling fins; a weapon barrel; a cylinder having at least a first layer of corrosion-prevention material and a second layer of a different corrosion-prevention material, the cylinder interposed between the weapon barrel and the cooling fins; and a plurality of corrosion-prevention inserts interspersed throughout at least one of the first layer and the second layer, the plurality of corrosion-prevention inserts being orthogonal to (i) at least one of the first layer and the second layer, and (ii) the weapon barrel, wherein: an inner surface of the first layer abuts an outer surface of the weapon barrel; and an outer surface of the second layer abuts an inner surface of the plurality of cooling fins; an inner surface of the first layer abuts an outer surface of the weapon barrel; and an outer surface of the second layer abuts an inner surface of the plurality of cooling fins; wherein, when ammunition is fired through the weapon barrel at a high rate, the first layer, the second layer, and the corrosion-prevention inserts permit the cooling fins to dissipate heat away from the weapon barrel while simultaneously protecting the weapon barrel from corrosively reacting with the cooling fins.
