WOL FZSANG W KPAUSS BY Patented Feb. 10,, 1953 RADIANT HEATING PANEL Wolfgang W. Krauss, Aurora, Ohio, assignor to Republic Steel Corporation, Cleveland, Ohio, a corporation of New Jersey Application October19, 1946, Serial No. 704,495 7 Claims. (01. 257-124) The present invention relates generally to the heating art and is particularly concerned with "novel panels for radiant heating systems and with novel elements comprising said panels.

A considerable variety of means for conveying heating fluids throughwalls, ceilings and floors -of buildings for radiant heating of the 'rooms thereof have been developed. Heretoiore, how- -'ever,*there'has never to my knowledge been conceived or employed a means equally suitable for use with both hot water type systems and hot air type systems despite the obvious and important advantages of such means.

'By virtue of the present invention, panels for radiant heating systems which are usable interchangeably with hot air type and hot water type heating means, are available for the first time. Channels and panels of this invention are of simple construction and consist of a minimum number of different parts and, in contradistinction to the vmeanspresently employed, are readily assembled and installed and disassembled, and have a substantially greater heating efficiency than conventional means which require cement or plaster radiating surfaces instead of metal radiating surfaces.

Those skilled in the .art will gain a further understanding of the present invention by referring to the drawings accompanying and forming a part of this specification, in which Figure 1 is a perspective fragmentary view of a hot air radiant heating system comprising panels .of this invention;

v.Figure 2 is an end elevational view of a hot water or steam radiant heating system including panels of this invention comprising the ceiling of a room;

Figure 8 is a view insection of a panel compris- "in'g channels of the Fig. '7 type and a hot Water or 'steampipe;

Figure 9 is a perspective fragmentary view of still another type of channel of this invention; :and

Figure '10 is a sectional view'of a panel com- "posed of channels of the type shown in Fig. 9 and a steam or hot water pipe.

Similar reference characters refer to similar parts throughout the several views.

Generally, the illustrated panels L comprise a plurality of rows of channels P in whichadjacent --channels are-disposed substantially side by side to --dfine a -s1ibs'tantially continuous plane surface,

means M for securing the rows together to-define a passage for fluid, and means S for securing the panels to a supporting structure such as ceiling joists.

There are a variety of forms of channels P, as illustrated, but each of these channels comprises an-elon'gated metal sheet having a body portion and opposed side portions shaped to engage complementary sides of adjacent channels. The pan of Fig. 3 has an elongated body portion I2, an edge portion l3 which defines a side of the channel and an edge portion l4 which defines another side of the channel opposed to the first mentioned side. The edge portion is is shaped to define a flange l5 disposed substantially parallel to said body portion. The flange I5 is provided with a plurality of substantially aligned apertures l6 and is substantially co-extensive with the edge 13. The edge 13 in the section between the body and flange I5 is further provided with a plurality of slots I! which are substantially aligned along the length of said section. The edge portion I 4 is provided with a plurality of tongues Is to be received in slots ll of an adjacent channel of similar construction.

The channel of Fig. 5 is generally similar to that of Fig. 3,. having an elongated body-portion 20 and edge portions 2| and 2-2 defining opposed sides of the channel. The edge 2| defines a flange 25 disposed substantially parallel to the 'body 20, and defines a recess 26 extending substantially the full length of edge 2!. The flange 25 is provided with a plurality of substantially aligned apertures 28 and is substantially coextensive with edge 2|. The edge 2| is shaped to define a recess 26 of substantially V-shape in cross-section in the portion of the side between the flange 25 and the body 20. The edge 22 defines a projecting portion 29 to be received'and closely fitted in a recess 26 of an adjacent channel of similar construction.

The channel of Fig. '7 likewisejhas'a body'por- 'tion 30 and edge portions 3Iand 32 defining opposed sides of the channel. The edge 31 defines a flange 35 disposed substantially parallel to the body 30, and provided with a plurality of substantially aligned apertures 36. The edge 3| is shaped to define a. recess 3! of substantially U- shape in cross-section in the portion between the flange 35 and the body 39. The edge 32 defines a projecting portion 38 to be received and closely fitted in a recess 31 of an adjacent channel of similar construction.

lhe channel of Fig. 9 resemhlesthose described above, having an elongated body M3, and edge portions ii and 42 which define opposed sides of the channel. The edge M defines a flange 45 which is disposed substantially parallel to the body it and is provided with a plurality of substantially aligned apertures 45. The edge' lz comprises a ortion adiacent to, and disposed at substantially right angles to, body -38, and a portion directed at said body and defining a V- shaped element in cross section. The edge portion 4| is appropriately shaped to receive an edge 42 of a similar channel in close fitting engagement, as described.

Some of the channels may be provided with apertures 54 in their body portions to receive means S. As shown in Figs. 3, 5, '7 and 9 these apertures are preferably substantially aligned along the length of the body.

One form of panel L of this invention comprises a row of channels B disposed substantially side by side with the projecting portion of one channel disposed in engagement with the adjacent channel in the recess of said channel. Panels of this form may cooperate with a surface, such as a portion of a wall or ceiling of a room, to define adjacent fluid passageways open at the ends, as shown in Fig. 4. Attachment of such panels to said wall or ceiling may be made by screws or studs S extending through apertures in the flanges of the channels.

Another form of panel L comprises two opposed rows of channels P in which adjacent channels are disposed side by side to define a substantially continuous surface. The flanges of opposing channels are disposed with openings in register and are secured together, as shown in Figs. 2, 6, 8 and 10 by means of bolts 56 and nuts 5! engaged therewith, comprising means M. In this form a plurality of adjacent passageways 53 communicating with each other are defined.

Heat may generally be delivered to panels L by means of a hot air header connecting the passageways of the panels with a furnace, or by means of a steam or hot water pipe 58. As shown in Figs. 2, 6, 8 and 10, these pipes are disposed between upper and lower courses of panels, being gripped between opposed flanges and held in position relative to the panels. Each of these pipes defines in plan view, as shown in Fig. 9, a series of relatively closely spaced, elongated and jointed U-sections. The U-sections are disposed across a plurality of passageways of the panels and extend at substantially right angles to sides of the channels comprising said panels. In assembling panels of this invention, the channels are disposed substantially side by side in a row with the projecting side portion of one channel disposed in close fitting engagement with the adjacent channel being received in the recess of the side of that channel. If the panel is to include a steam or hot water pipe, after the; j

manner shown in Fig. 2, such pipe is disposed between the opposed flanges 15 of two rows of channels. The rows of channels are secured together in this arrangement by means M comprising bolts 5!) disposed through registered apertures in the opposing flanges and nuts El threadwise engaged with said bolts. The panel may be secured to a wall, joist, truss or the like, by means S comprising studs, as illustrated in Fig. 2, the studs extending through apertures 54 and engaging said wall or other supporting structure.

In assembling the panel shown in Fig. 1, two rows of channels comprising channels arranged in edge to edge engagement as described are disposed as an upper and a lower course and are disposed at right angles to each other. That is, the flanges of one course extend in a direction at right angles to the flanges of the other course. These rows are secured together by means M disposed through registered apertures in opposed flange portions of the upper and lower courses, and are secured to a supporting structure by studs S, as above described.

Panels 0! the type illustrated in Fig. 10 may be made by assembling pairs of the Fig. 9 type in rows in which adjacent channels are disposed in close fitting engagement, the projecting side portion 42 of one channel being received in the recessed side portion M of the adjacent channel. A row including the channels having apertures 54 to receive studs S is disposed against the supporting wall or ceiling surface and the studs S are inserted into those apertures and into engagement with said wall or ceiling. A second row of channels, in which a strip is Welded to the edge of each side 4! below the flange 45, is then secured to the supported row by means M and a hot water or steam pipe 66 is gripped between the two rows, as shown.

A radiant heating assembly may include a plurality of panels L disposed in edge to edge contact to define elongated adjacent passageways for fluid and to define a surface constituting a floor or ceiling of a room. In the event that the heating fluid is steam or hot water and pipes are employed to convey it to the radiating surfaces of the panels, the ends of the passageways of the panels of the assembly may suitably be blocked to prevent flow of air into or out of these passageways. If the system involves the use of hot air as a heating means for the radiating surface of the assembly, suitable ducts for delivering air into the passageway within the assembly and for removing air from these passageways ought to be provided. In the latter case, all the ends of the assageways not communicating with the source of hot air through such ducts are preferably blocked to prevent the flow of air into or out of the passageways.

Having thus described the present invention so that others may be able to understand and practice the same, I state that what I desire to secure by Letters Patent is defined in what is claimed.
