Application May 17, 194s, semi No. 481,254 (ci. .12s-211) 3 Claims.
This invention appertains to an improvement in solar water heaters generally, and more particularly to a type thereof for maintaining a supply of heated water for household and other uses.
An object of the invention is to provide a water heater of this character, which is of an extremely simplified construction and arrangement, and
one that affords a maximum of heat absorption by the water, during its flow through the heater body to a point of storage and distribution, in a minimum time period of exposure to the rays of the sun.
Another object of the invention has to do with the provision of a solar water heater, wherein a unitary hollow metal body is formed of two thin metallicvsheets, preferably copper, with one,oi the sheets shaped to provide a tortuous or zigzag passageway that takes'the form of a substantially wide and shallow duct having oppositely i angled runs that slope upwardly from a water inlet to a water outlet and branches extending between pairs of adjacent of the runs to divert a portion of the ow therethrough for subsequent discharge back into the main ow for its commingling therewith, and the other of the sheets laid over and secured to the one sheet to enclose the passageway and presenting a at heat transferring surface for exposure to the sun's rays.
are provided with service connections 5 and 6, respectively, the connectionl 5 for the admission oi' a cold water supply, and' the connection 6 for the delivery of heated water to a point of storage and distribution.
The branch, or secondary, channels or ducts 3 connect a lower run, of the main channel or duct 2, with the next higher run thereof, substantially as is shown in Figure 1, the purpose of which is to divert a portion of the water flow in a lower y run and discharge it back into the main flow With these and other objects and advantages in view, the invention resides in the certain new and useful combination, construction and arrangement of parts, as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawing, in which:
Figure 1 is a horizontal section through the heater unit and its support, in accordance with the invention;
Figure 2 is an enlarged vertical transverse section on line 2-2 of Figure l; and, Figure 3 is an enlarged fragmentary vertical sectional detail on line -3-3 of Figure 1 showingthe manner of assembly of the parts.
Referring to the drawing, the-embodiment of the invention, as it is exemplified therein, is comprised in a substantially ilat hollow metallic body, of sheet metal, preferably copper, formed of two superimposed sheets I and I3. 'Ihe lower sheet I is shapedv to provide a main tortuous channel or duct 2 having oppositely angled runs sloping upwardly and merging one into the other through rounded portions 4, thus forming a continuous and unobstructed passageway extending parallel inlet and outlet runs 2a and 2b, respectively. The free ends of the inlet and outlet runs 2a, 2b,
through the higher run, thus increasing the heat transference to the water ow from the exposed surface of the heater body; the branch or secondary channels or ducts 3 being arranged to discharge water therefrom at points in proximity to the rounded portions 4, at one side of the heater body, to obtain an ejector 'eiect that materially increases the upward ow of the water through the main channels or ducts 2. The main channel or duct 2 is' preferably made substantially greater inwidthI than that o f the branch or secondary channels or ducts 3, for instance,l the width of the channel or duct 2 is twice that of l the branch or secondary channels 3, and all of the same shallow depth, e. g., one-eighth of an inch for purposes of the present description, it is suggested that the width of the main channel or duct 2 be two (2) inches, and that of the branch or secondary channels or ducts 3, one (1) inch.
In' assembly, the lower plate or'sheet I is secured to a wooden base I2 with nails or screws, preferably of copper, which are uniformly spaced -along a flange l, anguiarly bent 'outward from the end and side edges of the plate or sheet and, also, at points between the several runs of the main and branch channels or ducts 2, 3, to prep vent any twisting or swelling of the metal under water pressure. The lower plate or sheet I is backed, as at I0, with a sheet of tin foil, or other reflecting material, with the reecting surface uppermost. This reflector I0 is interposed between the plate or sheet I and the base I2 and is secured in place by the aforesaid nails or screws, along with the plate or sheet. The upper plate or sheet I3 is laid over the channeled side of the lower plate or sheet I and is secured thereto at its end and side edges by rivets I4 and, also, by
continuous soldering, as at I5, along all lines of contact with the plate or sheet I .and the side and end walls of the channels or ducts 2, 3. The unit, as thus constructed and'arranged, `is preferably enclosed within a frame, preferably 'of metal, i
such as copper, to the under side of which the base I2 is secured. This frame It has its upper open side closed by a pane or sheet of a transparent material, i1 that is mounted in a sashlike frame i8 detachably fastened to the frame It by means ot screws or the like I9. The spacing of the transparency I1 above the upper side of the heater body is'preferably slight, say, about two (2) inches.
Having thus fully described our invention, what we claim is:
l. In a solar water heater, a thin, substantially.
said inlet and outlet runs, the meeting ends of said runs being interconnected by rounded portions, said body being provided withbranch passageways connecting adjacent of the intermediate runs to divert a portion of the water ilow in a lower run and discharge it into the next higher run ata point adjacent a rounded portion of the main passageway.
2. The invention as in claim l, with said main passageway and said branch passageways being substantially rectangular in cross section.
3. The invention as in claim l, with said branch passageways having a cross sectional area substantially less than that of said main pas- 15 sageway.
