Abstract
A powder coated aluminum barbecue pit burner that burns gas in the same way that stainless steel burner tubes do, but last longer and do not rust. The use of powder coated aluminum makes the burner according to the present invention corrosion resistant. Additionally, the powder coated aluminum burner of the present invention also contain a heat sink element that prevents the temperature of the tubes from getting too high. Controlling temperature and using powder coated aluminum burners, instead of stainless steel, ensures that the burner will last longer. Another embodiment utilizes a water cooled system in connection with the heat sink element.
Claims24
A burner construction for use with combustible fuel comprising:
- a burner formed from powder coated aluminum;
- a longitudinal passage formed in the burner, with an inlet connected to the longitudinal passage, wherein the longitudinal passage receives combustible fuel through inlet and the combustible fuel is combusted in the longitudinal passage;
- a plurality of combustion holes along an exterior of the burner and extending into the longitudinal passage, and
- at least one heat sink formed of powder coated aluminum and having a first end that is connected to the burner and extends away from the burner terminating at a second end.
A barbecue arrangement comprising:
- a firebox with an exterior that has a bottom surface and a plurality of perpendicular sides extending from the bottom surface of the exterior, and an interior that has a bottom surface and a plurality of perpendicular sides extending from the bottom surface of the interior;
- at least one burner formed from powder coated aluminum and mounted in the interior of the firebox;
- at least one heat sink having a first end connected to the at least one burner and extending away from the at least one burner and terminating at a second end, and
- a thermal management device in contact with the second end of the at least one heat sink for removing heat transferred through the at least one heat sink from the at least one burner.
A barbecue arrangement comprising:
- a firebox having a bottom surface and at least one perpendicular side;
- at least one burner slot formed on the bottom surface, the at least one burner slot extends from the bottom surface to an outside bottom surface of the firebox;
- a cool air inlet guide adjacent from the at least one burner slot and extending perpendicular to the outside bottom surface;
- at least one burner formed from aluminum for combusting fuel and emitting heat, and
- an aluminum heat sink connected to the at least one burner and extending away from the at least one burner, wherein the aluminum heat sink extends through the at least one burner slot and past the outside bottom surface of the firebox so that a portion of the aluminum heat sink is outside of the firebox, while the at least one burner and a portion of the aluminum heat sink is inside of the firebox.
