Patent number: 9022298Abstract: A system may include a tube through which hot fluid is transported from one end to another, wherein the tube radiates heat energy and transfers heat energy to surrounding air by convection. The system may also include a reflector that reflects the radiated heat and a hood that captures the heat energy from the surrounding air through convection, wherein the hood radiates the captured heat energy. The reflector may include a bi-involute curved surface.Type: GrantFiled: September 21, 2009Date of Patent: May 5, 2015Assignee: Reznor LLCInventors: Jean-Pierre Catteau, Gerald Capaldini
