A space heating device which utilizes infrared lamps has enhanced heat transfer, and achieves an air flow velocity increase of approximately 30 percent, resulting in increased efficiency. A heat exchanger comprising a plurality of spaced, parallel copper tubes, and a plurality of spaced, parallel aluminum fins connected and extending perpendicular to the tubes, is mounted above the infrared lamps and in an air flow path within a casing so that air is circulated by a fan from a cool air inlet, past the lamps, beneath, around, and above the heat exchanger, through the tubes of the heat exchanger, and through the spaces between the fins and tubes, to the heated air outlet. Bottom portions of the fins are coated with black carbon paint to enhance heat transfer, and curved deflectors are provided adjacent the bottom of the lamps and adjacent the top of the heat exchanger on one end thereof, to facilitate guiding of the air in a generally S-shaped path through the casing. The fan is electrically connected to the lamps so that when one is on, all are on, and a thermostat responsive to ambient temperature adjacent the fan controls the fan and lamps. A high temperature switch placed within the casing cuts off the 120 volt supply of current to the fan and lamps if the temperature in the casing exceeds a predetermined level. |

DETAILED DESCRIPTION OF THE DRAWINGS The exemplary space heater 10 illustrated in FIGS.
1 and 2 includes many components in common with the space heater illustrated in U.
S.
Pat.
No.
4,309,594.
For example the unit includes a casing 12 having a bottom 16, a removable top 14, sidewalls 20 and 24, and end walls 18 and 22.
Disposed in end wall 18 is a cool air inlet to the casing 12, preferably defined a grill 34, while in the end wall 22 a heated air outlet from the casing is provided, preferably defined by grill 32.
Provided in the end 18 is an opening 119 through which a conventional electrical cord (not shown) extends for connecting the electrical components within the casing 12 to a conventional household 120 volt a.
c.
line.
Legs 26, 28 may be provided for supporting the casing 12.
Other conventional components of the space heater 10 illustrated in the drawings include a fan 84 mounted within the casing by mounting piece 82, including to interior end wall 78, the fan 84 being driven by electric motor 128, and also supported on interior floor 40.
An electrically powered heat source is provided within the casing which is preferably provided by a plurality of infrared lamps 92 which are mounted by lamp sockets 94 in the floor 40.
Above the heating chamber 38 are various other casing components including a ceiling unit 60 including U-shaped support brackets 69, 71, support plates 72, and handles 74, 76 which can used to remove the ceiling structure 60 from within the casing.
Support plate 72 of the unit 60 is normally supported by interior casing components 56, 58, with side portions 64 extending downwardly from plate 72.
The side portions 64 are bent inwardly at 68, 70 to provide support for a heat exchanger.
According to the present invention a heat exchanger 153 is provided in the casing 12.
The heat exchanger 153 according to the invention includes a plurality of spaced, parallel tubes 154 of high heat conductivity material, such as copper.
The tubes each have a first end 155 thereof, and a second end 156, and a pair of angle mounting brackets 157, 158 are provided adjacent the ends 155, 156 respectively for mounting the heat exchanger above the lamps 92
