Abstract
One aspect of this disclosure provides a finger baffle for a heating furnace. This embodiment includes an elongated support plate having a length, and at least one finger baffle extending outwardly and in a vertically oriented direction from the elongated support plate. The at least one finger baffle has a width that extends along the length of the elongated support plate. The finger baffle may be employed in a high-efficiency gas furnace.
Claims20
A finger baffle for a heating furnace, comprising:
- an elongated support plate having a length;
- and
- at least one finger baffle extending outwardly and in a vertically oriented direction from said elongated support plate, said at least one finger baffle having a width that extends along said length of said elongated support plate.
A high efficiency gas furnace, comprising:
- a housing;
- a primary heating zone located within said housing that includes spaced apart primary heating chambers, wherein each of said primary heating chambers has a pre-determined hot spot associated therewith and located adjacent an outlet end of each of said primary heating chambers;
- a secondary heat exchanger and condenser zone located downstream of an air flow path from said primary heating zone;
- a finger baffle, comprising:
- an elongated support plate having a length;
- and
- spaced apart finger baffles extending outwardly and in a vertically oriented direction from said elongated support plate, each of said finger baffles having a width that extends along said elongated support plate and a length that extends from said elongated support plate to said pre-determined hot spot;
- and
- a blower located within said housing proximate and downstream of said air flow path from said secondary heat exchanger and condenser zone.
A method of fabricating a finger baffle for a heating furnace, comprising:
- forming an elongated body having a length from sheet metal;
- forming spaced apart finger baffles from said elongated body;
- and
- bending said finger baffles such each of said finger baffles extend outwardly and in a vertically oriented direction from said elongated support plate, each of said finger baffles having a width that extends along a length of said elongated body.
A method of fabricating a high-efficiency gas furnace, comprising:
- providing a housing;
- placing a primary heating zone within said housing that includes spaced apart primary heating chambers, wherein each of said primary heating chambers has a pre-determined hot spot associated therewith and located adjacent an outlet end of each of said primary heating chambers;
- placing a secondary heat exchanger and condenser zone within said housing, located downstream of an air flow path from said primary heating zone;
- attaching a finger baffle to a frame of said primary heating zone and adjacent said outlet end of said primary heating chambers, said finger baffle comprising:
- an elongated support plate having a length;
- and
- spaced apart finger baffles extending outwardly and in a vertically oriented direction from said elongated support plate, each of said finger baffles having a width that extends along said elongated support plate and a length that extends from said elongated support plate to said pre-determined hot spot;
- and
- placing a blower within said housing proximate and downstream of said air flow path from said secondary heat exchanger and condenser zone.
The method of 19, wherein a spacing of said finger baffles corresponds to a spacing of said primary heating chambers such that each one of said finger baffles is located adjacent a pre-determined hot spot of a different one of said primary heating chambers when said finger baffle is attached to said frame of said primary heating zone.
