Benefits of technology

[0007] When the cylinder is formed of copper, the copper is pretreated at a temperature and for a time sufficient to soften the copper and to partially blacken the surface thereof. The absorptivity and emissivity of the cylinder as a heat exchanger is improved thereby improving the thermal efficiency of the space heater. When the cylinder is formed of aluminum, the aluminum is anodized and electrolytically colored or dyed dark on the inside surface.

Problems solved by technology

With the dwindling supply of fossil fuels and their associated spiraling costs, more homes and businesses are using space heaters as their primary or secondary heating source.
Inefficient systems, such as found in the prior art, require the use of excess amounts of energy, thus increasing the cost of operation.

Embodiment Construction

[0017] Referring to the drawings more particularly by reference character, reference numeral 10 refers to a space heater in accordance with the present invention. Space heater 10 comprises an exterior case 12, a heater core support 14 mounted inside exterior case 12 and a heater core 16 supported by heater core support 14.

[0018] Exterior case 12 is a box-like structure including a front wall 18, a rear wall 20, a top wall 22, a bottom wall 24 and side walls 26, 28. An air inlet 30 is provided in rear wall 20 and an air outlet 32 is provided in front wall 18. Air inlet 30 and air outlet 32 are covered with protective grilles 34, 36, respectively. As illustrated in the drawings, front wall 18 and top and bottom walls 22, 24 may be integrally formed as a wrapper to which side walls 26, 28 are joined with sheet metal screws 38 or by other conventional methods of construction such as welding, brazing and the use of fasteners, or combinations of methods as is known in the art. Rear wall ...

Abstract

A space heater with a linear source of infrared radiant energy in heat exchange relationship with a heat exchanger formed of copper or aluminum material. The copper is pretreated to soften the copper and partially blacken the surface thereof. The aluminum is anodized and electrolytically colored dark. The space heater is thermally more efficient than a comparable space heater wherein the copper or aluminum has not been pretreated. The linear source of infrared radiant energy and heat exchanger are mounted in a heater core that is thermally insulated by an air jacket from an exterior case.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a space heater which generates heat by passing an electrical current through a linear source of infrared radiant energy in heat exchange relationship with a pretreated copper or aluminum heat exchanger. [0003] 2. Brief Description of the Prior Art [0004] With the dwindling supply of fossil fuels and their associated spiraling costs, more homes and businesses are using space heaters as their primary or secondary heating source. After safety, the most important feature to be looked for in a space heater is thermal efficiency. Inefficient systems, such as found in the prior art, require the use of excess amounts of energy, thus increasing the cost of operation. BRIEF SUMMARY OF THE INVENTION [0005] In view of the above, it is an object of the present invention to provide a more heat efficient space heater. Other objects and features of the invention will be in part apparent and in part ...
