<p>A modular infrared space heater device (10) includes a housing (12) having an air inlet (24) and an air exhaust (50). An enclosure (27) is spaced within housing (12) and forms a heating chamber (30) having an inlet (28) communicating with the housing inlet (24) and a plurality of outlet openings (48) communicating with the exhaust (50). A plurality of open-ended ferrous metal conduits (44) are supported at one end from a ferrous metal sheet (42) in the chamber (30) between the outlet openings (48) and a plurality of infrared lamps (34). Each conduit (44) extends through a different one of the outlet openings (48) with sufficient clearance to provide an air flow passage between the conduit (44) and the boundary of the opening (48). A refractive lens plate (39) having a plurality of convex focussing surfaces (40) is provided between the lamps (34) and conduits (44) to focus infrared radiation on the supported ends of the conduits (44). A fan (22) circulates room air to be heated through inlet (24) into the heating chamber (30) and over the lamps (34), metal sheet (42) and conduits (44) therein, through conduits (44) and openings (48) and out air exhaust (50). </p> |
