Description

June 6, 1967 w. H. ARMSTRONG HEAT TRANSFER DEVICE Filed April 26, 1965 INVENTOR. w! a United States Patent 3,323,582 HEAT TRANSFER DEVICE William H. Armstrong, 197 Sandwich St., Plymouth, Mass. 02360 Filed Apr. 26, 1965, Ser. No. 450,840 2 Claims. (Cl. 165-49) This invention relates to a heat transfer device.
Reference is made to my pending patent application Ser. No. 385,978, filed July 29, 1964.
One object of my invention is to provide a heat transfer device which can be used with stock radiation panels commonly used to assemble ceilings.
Another object is to provide such a device that includes -a conduit for the heating fluid without having to include an outside cover for the conduit.
Still another object is to provide such a device that includes heat transfer members that are integral with said conduit and which receive and hold the sides of two adjoining panels between them.
A further object is to form my device as an integral uiiit, thus simplifying its production and also making it possible to use a material of high thermal conductivity, such as aluminum, and that is also relatively light in weight and low in cost.
The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrange ment of parts such as is disclosed by the drawing. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, I am not to be limited to the construction disclosed by the drawing nor to the particular parts described in the specification; but am entitled to all such changes therefrom as fall within the scope of my claims.
In the drawing:
FIG. 1 is a perspective view showing my heat transfer device connected to two metallic panels.
FIG. 2 is a fragmentary top plan view of the device and panels shown in FIG. 1.
FIG. 3 is an end elevational view of the device and panels shown in FIG. 1, with the addition of a supporting beam.
FIG. 4 is an enlarged, sectional view taken on the line 44 of FIG. 2.
FIG. 5 is an enlarged, sectional view taken on the line 55 of FIG. 2.
FIG. 6 is an enlarged, perspective view of a mounting member for my device.
FIG. 7 is a sectional view, similar to said FIG. 4, omitting the panel, and showing a modified form of conduit.
As illustrated, my heat transfer device has an elongate conduit 10 which, as shown, is an elongate tube that is circular in cross section. Heat transfer members 12 and 14 are spaced apart as at 15, and extend outwardly from said conduit 10 and are preferably formed integral therewith of a metal of high thermal conductivity such as aluminum.
Said heat transfer members 12 and 14 each has an inner holder portion 16 and 16a respectively which are shown extending slightly diagonally outward from said conduit. Extending from said inner holder portions 16 and 16a are outer bead or protruding portions 18 and 18a respectively which provide opposite thereto inner recesses 20 and 20a respectively. Extending from said bead portions 18 and 18a the holder portions continue as outer holder portions 22 and 22a from which respectively extend connector portions 24 and 24a diagonally outward.
Flat contact portions 26 and 26a extend respectively outward from said diagonal portions 24 and 24a.
3,323,582 Patented June 6, 1967 ice To attach said heat transfer device to a building beam 28 or other external support I provide a mounting member 30 slidable on said conduit. Said member 30 has two arcuate- shaped sides 32 and 34 that extend part way 3 around said conduit 10 and which have retaining portions 36 and 38 respectively extending from said sides. A connector 40 is held between said retaining portions 36 and 38 by a bolt 42 extending through it and the latter two portions, being held by a nut 44.
Said connector 40 extends beyond said portions 36 and 38 and may be connected to a support such as said beam 28 by a screw 46 extending through a hole .provided therein.
My device is used in combination with well known metal panels 50 each having a perforated face 52 the inner surface of which is commonly provided with a bead or ridge 54 extending crosswise as shown. These beads 54 are formed at a predetermined distance apart, such as 12 inches as when a relatively long panel is used. Said panel 50, as shown, has two relatively long sides 56 and 58 extending angularly from said face 52 and also two relatively short sides 60 and 62 similarly extending from said face.
Each of said sides 56, 58, 60 and 62 has a beaded portion 64 at the inner surface thereof intermediate the outer and inner extremities of each of said sides.
In said FIG. 7, I show a modified form of conduit 10 having inwardly projecting fins 66 at the interior. These serve to quiet the flow of fluid should it be under pressure suiiiciently to cause a noise as it flows.
In use, a long side 56 of one panel and a long side 58 of another panel as shown, adjoin each other. Both of these sides extend into the space 15 provided in my heat transfer device. The said panel beaded portions 64 on each of the two sides 56 and 58 extend into the inner recesses 20 and 20a. Said contact portions 26, and 26a contact the faces of the two adjoining panels which is necessary to get efiicient heat transference from my device to said panels.
Since my device will commonly extend more than the distance between one said short side 60 or 62 and a said bead 54, and may extend more than the distance between said two short sides 60 and 62, I provide cut-outs 70 in said heat transfer members 12 and 14 that extend through said holding portions 22 and 22a, said diagonal portions 24 and 24a and said contact portions 26 and 26a.
These cut-outs 70 are deep enough to permit said contact portions 26 and 26a to lie flat on said panel faces 52 where any of said panel sides are encountered.
Said panels, when installed, occupy the space below the conduits and present a heat radiation surface to the room. A fluid, such as hot water, for instance, or a cooling fluid, is circulated under pressure through said conduits 10, from supply conduits, not shown, and the heat exchange occurs, by means of said heat transfer members 12 and 14 and the contact of said contact portions 26 and 26a with said panel faces 52.
What I claim is:
1. A heat transfer device in combination with two rectangularly-shaped panels each having a face portion and four sides extending angularly from the latter, one said side of one said panel adjoining a said side of the other said panel, a bead projecting from the inner surface of each said face portion and extending crosswise thereof between two of said sides of each said panel respectively that are oppositely disposed, two other of said sides of each said panel being oppositely disposed, said device embodying an elongate and integral conduit of metal that is continuously circular in cross-section, and two heat transfer members spaced apart integral with and extend ing outwardly from said conduit, said adjoining sides' extending into the space between said heat transfer members, each of the latter embodying a contact portion extending angularly from the adjoining portion and respectively contacting a said panel face portion, each said transfer member having cut-outs therein into which said other two oppositely disposed sides and said bead respectively extend.
