Abstract

A barrel cooling system for a weapon includes a corrosion prevention cylinder between a barrel and cooling fins arranged around the cylinder.

Claims (42)

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.

2 . The corrosion prevention cooling system for a barrel of a weapon as in claim 1 , wherein the cooling fins are made from copper.

3 . The corrosion prevention cooling system for a barrel of a weapon as in claim 1 , wherein the barrel is made from steel.

4 . The corrosion prevention cooling system for a barrel of a weapon as in claim 1 , wherein the first layer is made from chromium, and the second layer is made from brass.

5 . The corrosion prevention cooling system for a barrel of a weapon as in claim 1 , wherein the first layer is made from brass, and the second layer is made from chromium.

6 . The corrosion prevention cooling system for a barrel of a weapon as in claim 1 , wherein the plurality of corrosion-prevention inserts interspersed throughout at least one of the first layer and the second layer are made from nickel.

7 . The corrosion prevention cooling system for a barrel of a weapon as in claim 1 , further comprising a protective shield positioned over at least a portion of the plurality of cooling fins, the protective shield having vents to permit (i) ambient air to circulate about the cooling fins, and (ii) heat to escape the system.

8 . 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 being made of brass, nickel, or chromium, and a second layer of a different corrosion-prevention material being made of brass, nickel, or chromium not forming the first layer, the cylinder being 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.

9 . The corrosion prevention cooling system for a barrel of a weapon as in claim 8 , wherein the cooling fins are made from copper.

10 . The corrosion prevention cooling system for a barrel of a weapon as in claim 8 , wherein the barrel is made from steel.

11 . The corrosion prevention cooling system for a barrel of a weapon as in claim 8 , wherein the first layer is made from chromium, and the second layer is made from brass.

12 . The corrosion prevention cooling system for a barrel of a weapon as in claim 8 , wherein the first layer is made from brass, and the second layer is made from chromium.

13 . The corrosion prevention cooling system for a barrel of a weapon as in claim 8 , wherein the plurality of corrosion-prevention inserts interspersed throughout at least one of the first layer and the second layer are made from nickel.

14 . The corrosion prevention cooling system for a barrel of a weapon as in claim 8 , further comprising a protective shield positioned over at least a portion of the plurality of cooling fins, the protective shield having vents to permit (i) ambient air to circulate about the cooling fins, and (ii) heat to escape the system.

15 . 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 being made of brass, chromium, aluminum, titanium, or nickel, and a second layer of a different corrosion-prevention material being made of brass, nickel, or chromium not forming the first layer, the cylinder being interposed between the weapon barrel and the cooling fins;

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; and

a perforated shield positioned over at least a portion 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.

16 . The corrosion prevention cooling system for a barrel of a weapon as in claim 15 , wherein the cooling fins are made from copper, polypropylene or polytetrafluoroethylene.

17 . The corrosion prevention cooling system for a barrel of a weapon as in claim 15 , wherein the barrel is made from steel.

18 . The corrosion prevention cooling system for a barrel of a weapon as in claim 15 , wherein the first layer cylinder is made from chromium, and the second layer is made from brass.

19 . The corrosion prevention cooling system for a barrel of a weapon as in claim 15 , wherein the first layer is made from brass, and the second layer is made from chromium.

20 . The corrosion prevention cooling system for a barrel of a weapon as in claim 15 , wherein the plurality of corrosion-prevention inserts interspersed throughout at least one of the first layer and the second layer are made from nickel, polypropylene, polytetrafluoroethylene and combinations thereof.
