Abstract
The present invention in its most simple form or embodiment is directed to a heat exchanger which provides for at least two heat exchange surfaces. The two heat exchange surfaces are defined by an inner wall or inner shell which separates a combustion region or combustion passage and at least one fluid passage defined by the inner shell, and an outer wall or outer shell. The space defined between the inner and outer shells being the combustion region or combustion passage. The combustion chamber is configured to provide for full and efficient fuel combustion without any flat surfaces upon which a flame of combustion could impinge. Because of the nature of the construction, the flame forms into a fan configuration allowing thorough mixture with the combustion air and thus providing for complete and efficient combustion.
Claims10
A heat exchange device for heating a fluid comprising an outer shell having an input end and an output end defining a first cavity therein;
- an inner shell within said first a cavity said inner shell defining a first fluid passage therein, said inner shell having an output section connected at one end to one end of a truncated and angled section, the other end of said truncated and angled section connected to one end of an input section the other ends of the output section and the input section being attached to a removeably affixed output end securing means and a removeably affixed input end securing means respectively, said securing means maintaining said space relationship between said outer shell and said inner shell;
- a combustion chamber at said outer shell input end said chamber defined by an arcuate surface of an inner surface of said outer shell and a horizontal and vertical plane, both planes extending from said input end securing means in a direction from the input end toward the output end, to about the one end of said truncated and angled section and from said arcuate surface to substantially a longer axis of said outer shell;
- a combustion region defined between said inner surface of said outer shell and an outer surface of said inner shell for containing and directing combustion gases along a path from said combustion chamber to an exhaust gas portal defined by a combustion gas exhaust means positioned substantially at said outer shell output end, said combustion gas path substantially enveloping said outer surface of said inner shell;
- and means for introducing a flame from a flame producing assembly into said combustion chamber in a manner to produce a flame having a fan configuration proximate to said arcuate surface and directing said flame at an angle of between about 90.degree. and 120.degree. to said longer axis of the outer shell said longer axis directed from the input end toward the output end of said outer shell.
