  • Seebeck active cooling device for caliber weapons
    Patent number: 8783154
    Abstract: A Seebeck active cooling device for use in conjunction with a weapon to cool the barrel, in order to reduce its weight, to remove the need for a second barrel, and to prolong its useful life. In particular, the cooling device employs a plurality of thermoelectric devices that convert the energy from the heat produced by the hot barrel during the operation to an electric current. The electric current powers a series of electric fans, which in turn, cool the barrel.
