HEAT EXCHANGER Filed May 20, 1929 INV EN TOR.
A TTORNEY Patented June 21, 1932 PATENT OFFICE FRED L. WAG-AR, or WAGAR, ALABAMA HEAT EXCHANGER.
Application filed May 20,
The invention relates to heat exchangers, wherein the heat of a fluent heating medium is to be transmitted to anotherfluent medium through an intervening septum or partition.
5 The main object of the invention is the provision of an apparatus or device whereby the greatest possible quantity of heat may be transmitted from one medium to the other, and incident thereto minimizing the quantity 10 of heat retained by the heating medium.
A further object is the provision of means in connection with one embodiment of the invention for the eflicient ventilation of an inclosed space, as a room, in which the apparatus or device is located.
The invention consists in certain novelties of construction and in the combinations of parts as herein set forth and claimed.
The accompanying drawing illustrates two examples of the embodiment of the invention, one in its simplest form, and the other with the addition of means for securing efiicient ventilation, including the introduction of pure fresh air to and the discharge of impure air from the inclosed space or room, the same being constructed and the parts combined according to the best modes of procedure I have so far devised for the purpose.
Figure 1 is a side view in elevation of a structure which may be used as a steam or hot water radiator.
Figure 2 is a cross section of Figure 1 taken on line 22.
I Figure 3 is a. side view in elevation of what is shown by Figure 1 with the addition of ventilating means and an electric heater.
Figure 4 is a Vertical cross section in elevation of Figure 3 on line 44 looking in the direction of the arrows.
Figure 5 is an enlarged part horizontal sectional view showing the construction of the side Walls of Figure 1.
A designates the main body part the wall r thereof comprised of sheets of corrugated metal, 1 and 2, preferably malleable iron, as it is less subject to oxidation or rusting, the corrugations of one sheet being disposed at right angles to the corrugations of the other sheet and the sheets secured together at their points or areas of contact 3 in any suitable 1929. Serial at. 364,575.
way, as by electrical welding or by mechanical means, as rivets. The body part may be of any desired shape in cross section, such as shown by Figure 2 or of other shape. At the opposite ends the adjacent sheets are secured together by filling pieces or rings 4, 4, thus forming an inclosed space for the reception of afiuid, such as steam or water. This body part as shown by Figures 1 and 2 may be used as a steam or hot water radiator, and when so designed should be provided with a pipe 5 and valve 6 adjacent each end for the entrance to the interior thereof of steam or hot water and the discharge of the same therefrom. Being made of sheets of corrugated metal, a very large area of radiating surface not only at its interior but also at the exterior is provided for contact with'the air to which the heat of the fluid at the interior of the device is transmitted. Moreover, as the corrugations of the exterior and interior sheets are at right angles, intricate and devious passageways are provided for the circulation of the steam or hot water, thus eifectively transmitting the largest possible quantity of heat from the heated fluid medium, as steam or water, to the fluid medium, as air, exterior to the sheets of metal constituting the body of the device. A
To the body part A as described may be added, as shown by Figures 3, 4 and 5, means for circulating aira casing B of the shape shown being spaced from the body A, part of the space, as at 7, being open at top and bottom for the upward passage of air being reheated in the'room and part of the space closed at the bottom, as at 8, and a conduit C provided in connection with air exterior to the room for the introduction of fresh pure air. The casing thus provides for a continuous circulation and heating of air within the room and also for the introduction of pure fresh heated air which is continually supplied and mixed with the heated air in the room, thus equalizing the temperature throughout the entire inclosed space or room.
When it is desirable to remove foul air from the room the top of the radiator body is closed by a plate, as 9, and a pipe 10 connected at one end with the space below the plate 9 and the other end extended to a chimney or outside the room for the discharge of the foul air. A damper 12 will control the size of the opening in the pipe. This pipe may have two branches 11, ll communicating with opposite sides of the radiator.
To provide a source of heat there may be added an electric heating device D of any well known type, and the same should be located within the body part A near the bottom thereof, as shown. The electric heater may be connected with any source of electrical energy in a well known way. \Vhen the heater is present the interior of the body portion may be closed by a plate 13 and openings 14: made in the wall of the body at opposite sides or ends for the upward passage of foul air within the room to the pipe 10; or, when it desired, the plate 9 may be omitted and the air within the room circulated through the interior of the body part A and discharged into the room.
A series of air-deflecting plates 15 may be obliquely disposed within the space above the electric. heater, the same radiating alternately from opposite surfaces of the interior of the body part A, one overlapping another, thus deflecting the heated upwardly passing air current against the interior surface of the corrugated sheet 1 and transmitting more heat to the sheet and the inclosed water. To adapt the apparatus shown by Figures 3 and etfor heating water the two pipes 5 may be connected with a hot water storage tank, as is obvious. A pipe and valve 16 should be provided for drawing the water from the interior of the body part when the same is used as a water heater.
From the illustrations and description it is clear that I have provided an apparatus or device in which the greatest possible heat exchange is efiected, the area of the metallic surfaces constituting the body part of the apparatus being as large as possible with the quantity of metal used in the constructions, and, moreover, there is provided intricate and devious passageways which retard the flow of the fluid within the inclosed space, thus retaining it for a longer period in contact with the heated surface.
Obviously, part of the apparatus may be used as a steam or hot water radiator, and with the additions the same may constitute an electric heating device, a hot water heater, a ventilator, a heater with means for exhausting foul air, heating pure fresh air and reheating the air within the room.
hat I claim is:
1. In a device of the character described, the combination of a hollow shell having an open passage therethrough, said shell consisting of concentrically arranged exterior and interior sheets of corrugated metal the corrugations of one sheet being disposed at angles to the corrugations of the other sheet and the corrugations of opposite sheets united at their points or areas of contact; means uniting adjacent edges of the sheets to form an inclosed space between the sheets openings to the said inclosed space with a pipe in each opening whereby fluid, as liquid, may be passed through the said inclosed space; and heating means for transmitting heat to the fluid between the corrugated sheets of the shell.
2. A heat exchange device comprising a hollow shell, said shell consisting of concentrically arranged exterior and interior sheets of corrugated metal, the corrugations of one sheet being disposed at angles to the corrugations of the other sheet, and the corrugations of opposite sheets united at their points or areas of contact, means uniting adjacent ends of the sheets to form an inclosed space between the sheets, and pipes for circulating fluid through the inclosed space between the sheets; the interior of said shell being open at eaclli end for the passage of air through the she I.
In testimony whereof I afiix my signature.
FRED L. VVAGAR.
