US12698944 - Thermoacoustic heat exchanger suppressor

A silencer core for suppressing and dissipating at least one of a sound, a flame, or a quantity of heat of a projectile fired from a firearm includes a thermoacoustic organic structure (TOS) extending along a central axis from a first end to a second end. The TOS defines a central bore extending along the central axis from the first end to the second end. The central bore enabling the projectile to pass through the TOS when fired from the firearm. The TOS also defines a network of interconnected passages or a mesh configured to move at least one of combustion gases, heat, or sound from the central bore to an outside diameter of the TOS. The TOS has a density between 1.5 g/cm 3 to 4 g/cm 3 .

The patent describes a silencer core designed to suppress sound, flames, and heat from projectiles fired from firearms, utilizing a thermoacoustic organic structure (TOS) with a central bore for projectile passage. This TOS features a network of interconnected passages to efficiently transfer combustion gases, heat, and sound to its exterior, with a material density ranging from 1.5 g/cm³ to 4 g/cm³.

Claim 1

1 . A silencer core for suppressing and dissipating at least one of a sound, a flame, and a quantity of heat of a projectile fired from a firearm, the silencer core comprising: a thermoacoustic organic structure (TOS) extending along a central axis from a first end to a second end, the TOS defines: a central bore extending along the central axis from the first end to the second end, the central bore enabling the projectile to pass through the TOS when fired from the firearm, and a network of interconnected passages configured to move at least one of combustion gases, heat, and sound from the central bore to an outside surface of the TOS, wherein a material forming the TOS has a density between 1.5 g/cm 3 and 4 g/cm 3 . a thermoacoustic organic structure (TOS) extending along a central axis from a first end to a second end, the TOS defines: a central bore extending along the central axis from the first end to the second end, the central bore enabling the projectile to pass through the TOS when fired from the firearm, and a network of interconnected passages configured to move at least one of combustion gases, heat, and sound from the central bore to an outside surface of the TOS, wherein a material forming the TOS has a density between 1.5 g/cm 3 and 4 g/cm 3 . a central bore extending along the central axis from the first end to the second end, the central bore enabling the projectile to pass through the TOS when fired from the firearm, and a network of interconnected passages configured to move at least one of combustion gases, heat, and sound from the central bore to an outside surface of the TOS, wherein a material forming the TOS has a density between 1.5 g/cm 3 and 4 g/cm 3 . a network of interconnected passages configured to move at least one of combustion gases, heat, and sound from the central bore to an outside surface of the TOS, wherein a material forming the TOS has a density between 1.5 g/cm 3 and 4 g/cm 3 .
