HEAT DISSIPATION ASSEMBLY INCORPORATED INTO A HANDGUARD SURROUNDING A RIFLE BARREL

摘要

A heat dissipation assembly for use with a barrel forming a part of a firearm upper receiver. An annular shaped barrel nut is adapted to secure the barrel to the upper receiver. An elongated handguard is affixed to the barrel nut at a heat conducting location, the handguard adapted to surround a proximal extending portion of the barrel, the handguard having a plurality of apertures defined therethrough. At least one cooling element is located on an exterior of the handguard. A thermoelectric generator is incorporated into the handguard for transferring heat from the barrel nut to the cooling element. A fan component is integrated into the handguard and operated by the thermoelectric generator for drawing air through the apertures in order to provide additional cooling to the barrel.

主权项

1. A hand guard incorporated into a firearm having a heat generating barrel, said assembly comprising:
an elongated and tubular shaped body including a free floating tube overlaying the barrel in heat conducting fashion, a barrel nut secured to an open end of said tube and including a plurality of ventilation holes; a Seebeck module incorporated into said body and, in response to heat emanating from the barrel, operating at least one piezoelectric blower; and a rotating blade supported within an open interior of said body which is rotated by said blower to draw the heat from said body for discharge through said ventilation holes.
