Abstract

A heat exchanger for providing radiant heat, the device comprising a circular reflector which is inwardly dished on one side so to form a concave reflective surface of parabolic character, three circular heater coils of each a different size being positioned concentrically in front of the parabolic reflector, all of the heater coils being connected to a steam source by means of a hand operated controll valve, and the diametrically opposite side of the heating coil being connected to a steam outlet valve.

Davis, Jr. Attorney-Allison C. Collard [5 7 ABSTRACT A heat exchanger for providing radiant heat, the device comprising a circular reflector which is inwardly dished on one side so to form a concave reflective surface of parabolic character, three circular heater coils of each a different size being positioned concentrically in front of the parabolic reflector, all of the heater coils being connected to a steam source by means of a hand operated controll valve, and the diametrically opposite side of the heating coil being connected to a steam outlet valve.

1 Claim, 4 Drawing Figures MTENTED JUN 2 6 I973 SNEEIZUFZ HEATING COILS This invention relates generally to heat exchangers. More specifically the present invention relates to radiant heaters.

A principal object of the present invention is to provide an improved radiant heater which employes steam as a heat source for a series of heater coils positioned in front of a parabolic reflector that directs heat rays from the heater coils in a forward direction.

Another object of the present invention is to provide a heating coils construction that is designed particularly for being recessedinto a wall of a house for heating the rooms thereof.

Still another object of the present invention is to provide a heating coils construction which relatively thin so that it maybe conveniently fitted into a wall without taking up space within the room itself.

Yet a further object of the present invention is to provide a heating coils construction which thus replaces the bulky and space consuming steam radiators presently employed in many buildings.

Other objects of the present invention are to provide a heating coils construction which is simple in design, inexpensive to manufacture, rugged in construction, easy to useand'efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a front elevation view of the present invention,

FIG. 2 is a vertical cross sectional view taken on the line 2-2 of FIG. 1,-

FIG. 3 is a side cross sectional view taken on the line 3-3 of FIG. 1, and

FIG. 4 is an enlarged crosssectional view taken on the line 4--4 of FIG. 1.

Referring now to the drawing in detail, the reference numeral represents a heating coils construction of the present invention wherein there is a circular reflector 11 which upon its front side is inwardly dished to form a concave surface so to form a parabolic character. The reflector 11 is made perferably of an alloy material such as aluminum alloy and maybe made approximately' one-half inch thick.

An upper and lower embossment or

pad

12 and 13 respectively are integrally formed upon the front side 15 of the reflector, the pads providing support means for a plurality of heating coils 16 each one of which is of a different diametrical size and which are positioned concentrically upon the reflector. Each pad is provided with a plurality of transverse extending grooves 17 within each one of which one of the heating coils 16 is fitted and then rigidly secured by means of clamps 18 or 19, each of the clamps 18 and 19 being likewise provided with generally semi-circular grooves 20 for fitting over the heating coils. The clamps 18 and 19 are secured to the

pads

12 and 13 by means of securement screws 21.

The lower of the pads 13 contains a control valve 22 that is hand operated and which selectively controls the movement of live steam 23 from a steam pipe 24 to the heater coils 16.

The control valve 22 includes a rotating stem or cylinder 25 that is rotatably controlled by means of an external handle 26. The cylinder 25 has an elongated groove 27 along one edge thereof which communicates with a series of transverse extending openings 28 in the cylinder 25, the openings 28 each being adaptable to be aligned with openings 29 in the pad 13, the openings 29 each communicating with an opening 30 through the wall of the heatercoils 16 so to communicate with the interior thereof. The groove 27 of the cylinder 25 also communicates with an inlet opening 31 that communicates with the steam pipe 24. Thus steam can be controlled for moving from a steam source into the heating coils.

The upper pad 12 additionally supports a steam outlet valve 32 from which steam may escape and from which air is vented from the heating coils so to permit the steam to travel from a steam producing boiler and into the heating coils.

Appropriate O-ring seal means maybe provided between the reflector and the coils so to prevent the steam from escaping.

In operative use, it is now evident that when the device is mounted vertically within a wall, radiant heat is directed outwardly there from and into a room. The heating coils maybe of one-half inch diameter, and the entire unit maybe approximately 3 inches in width.

Thus there is provided an improved heating coils construction.

What I Now claim Is:

1. A radiant heater, comprising:

a circular reflector member, constructed of aluminum alloy, having a concave, parabolic-shaped surface for reflecting'heat rays outwardly;

a plurality of circular heating coils, each having different diameters, and mounted in a concentric arrangement in front of said concave surface of said reflector member, said heating coils having steam circulating therethrough;

an upper and a lower support pad, disposed on said concave surface of said reflector member, for supporting said plurality of heating coils;

a control valve, coupled to said lower pad, for controlling the flow of steam into said heating coils; and

a steam outlet valve, coupled to said upper pad, for

venting said heating coils to the atmosphere.
