Heat dispersing element

Abstract

A heat dispersing element for a standard propane torch head for the generation of silent heat. This heat dispersing element attaches directly to the head of a propane torch and operates silently. The heat dispersing element accepts the heat of the torch and silently disperses the heat through the burn plate and directs it outward silently. This is done through a series of openings.

DETAILED DESCRIPTION

(7) FIG. 1 shows the heat dispersing element 2 secured to a propane torch 40. The metal front 10 has multiple small holes or openings 20 therethrough.

(8) The heat dispersing element 2 also shows an element guard 42. The heat dispersing element 2 heats to temperatures that require it be safe from contact. The element guard 42 prevents the user from inadvertent contact and keeps them safe from the hot surface of the heat dispersing element 2. The heat dispersing element 2 is attached to a standard propane torch head 40. The torch 40 incorporates a standard tank 50 that contains the propane fuel. The tank 50 is secured within a base 44. Here the base is square and prevents the torch 40 from tipping over during operation. It should be understood that any base configuration that prevents the torch 40 from being knocked over is suitable.

(9) FIG. 2 shows the metal front 10 of the heat dispersing element 2 with a number of small holes 20. In this embodiment the main housing 4 is made from 1 square tubing with a 16 gauge thickness. The front measures 4 inches in length, center line of the front from one end to the other has nine 5/32 inch holes 20 drilled starting in the center and working out in both directions spaces 5/16 inch apart although these dimensions are not critical and the invention is not so limited.

(10) The 2.sup.nd and 3.sup.rd row holes 20 are spaced perpendicular with center row holes 20 but are spaced, for example, 5/16 inch to each side of the center and the holes 20 are drilled in an offset pattern from the canter line holes 20 with the 2.sup.nd and 3.sup.rd rows containing only 6 holes per line.

(11) FIG. 3 shows the heat dispersing element 2 from the first end 14. The housing 4 has top 6, a flat bottom 8 and a front 10. The housing 4 also has a back 12, a first side 14 and a second side 16 (shown in FIG. 4). There are a plurality of openings 20 therethrough, or small holes, through the front 10. There is an opening 22 therethrough of the back 12. There is another opening 24 therethrough that has a set screw 30 in it. This second opening 80 therethrough accepts the torch head of the propane torch 40 and locks into place with the set screw 30. This is the manner in which the heat dispersing element attaches 2 to the propane torch 40.

(12) FIG. 4 shows the heat dispersing element 2 from the top 6. The first side 14 and the second side 16 are cut from the housing 4 in a 45 angle from the front 6 to the back 12. The first side 14 and the second side 16 helps to radiate the heat that is generated from the heat dispersing element 2. Both the first side 14 and the second side 16 help reduce the noise produced by burning the propane fuel because their presence blocks noise that would otherwise escape if they were left open. The front 10 has a series of openings 20 therethrough that radiate heat in a silent manner. Here the inside flat surface 18 is shown with the single plate or burn plate 32 with openings 60 therethrough in phantom.

(13) The opening 22 through the center of the back 12 that is threaded 26 attaches to the main housing 4. This embodiment is threaded, however, it should be understood that this attachment in other embodiments can be welded. The other opening 24 has a set screw 30 to tighten the heat dispersing element 2 to the propane torch 40.

(14) FIG. 5 shows the burn plate 32 from the side. The burn plate 32 has a front 72 and a back 70. There is also a center point 34 or apex of the burn plate 32. The burn plate 32 attaches to the inside surface 18 of the front 10 of the heat dispersing element 2. The back 70 of the burn plate 32 faces the back 12 of the heat dispersing element 2. The apex or center point 34 of the burn plate 32 points toward the back 12 of the heat dispersing element 2. The apex 34 and pattern openings or openings 60 therethrough of the burn plate 32 and the front 10 of the heat dispersing element work in concert to silence any noise produced when propane fuel burns through the heat dispersing element 2.

(15) FIG. 6 shows the burn plate 32 from the front 72. The burn plate 32 has a first end 36 and a second end 38. Also shown are the openings 60.
