20080314378 | HEAT EXCHANGER - A furnace or other heat exchanger application for heating, ventilation, air conditioning and refrigeration systems having condensate control. Specifically, the disclosure includes condensate control for secondary heat exchangers for use with high efficiency furnaces, particularly for small tonnage systems, such as residential or unitary systems. The application provides condensate management to permit a plurality of furnace orientations while providing resistance to corrosion due to liquid condensate, while providing a furnace system that utilizes less expensive materials and is easily fabricated. | 12-25-2008 |
20090044793 | FURNACE BURNER BOX - A burner box for a furnace. The burner box includes a housing attached to the furnace. The burner box further includes a module configured to align and support a burner within the housing. The module is detachable from the housing and removable from the furnace burners. The module is detachable from the housing without disassembly or detachment of the housing from the furnace. | 02-19-2009 |
20120292000 | TURBULATORS FOR HEAT EXCHANGER TUBES - The present disclosure is directed to heat transfer turbulators that can be disposed within heat exchanger tubes. The heat transfer turbulators are designed to promote turbulent flow of a heat transfer fluid through the heat exchanger tubes. The heat transfer turbulators include a helically shaped body portion that extends within the tubes and is constructed at least partially of plastic. The heat transfer turbulators also include an extension portion that extends outside of the tube from the body portion and has an outer diameter that is greater than the inner diameter of the tube. | 11-22-2012 |
20130152834 | HEAT EXCHANGER - A furnace or other heat exchanger application for heating, ventilation, air conditioning and refrigeration systems having condensate control. Specifically, a condensate control for secondary heat exchangers is provided for use with high efficiency furnaces, particularly for small tonnage systems, such as residential or unitary systems. Condensate management permits a plurality of furnace orientations while providing resistance to corrosion due to liquid condensate. | 06-20-2013 |
