- This invention relates to radiators, andto devices for use with radiator sectlons for 1ncreas ng the radlatlng e ect thereof, or for increasln the radiatin effect and strengthening sai sections, an aims to provide improvements therein.

site radiator section comprlsing a fluid-containing envelo e and a surrounding portion having formed thereon means for increasing the radiating surface and for bafliing air flowing over said section, or for increasing said surface'and strengthening said sections,

particularly where the internal pressure to 16 which said sections may be subjected is high.

It further provides a composite radiator section formed of light sheet metal, in which the envelope portion is substantially seamless, as descrlbed in my Patent 1,599,510

2 granted Se t. 14,1926, and my ap lication for Patent erial No. 730,632 filed ugust 7, 1924, and is designedto lighten, reduce in size, and cheapen radiators and radiator sections, as compared with the ordinary cast metal radiators now largely in use.

The invention further provides a radiator of light metal construction capable of use with relatively high pressure heating fluids.

The invention further rovides radiator relatively cheap, ra id, eflicient and comfortable method of s eet metal stamping or drawing.

The invention further provides press-' formed parts generally applicable for increasing the radiatin effect of radiators, or for strengthening said radiators, or for both purposes.

Fig. 14 1s a wow il bodiment of radiator especially adaptable for use with high ressure heating fluid.

d Referring to sand drawings, numeral lo esi enve ope portion 12 and an attached or surroundmg portion 14.

The envelope rtion is preferably of light gauge meta and substantially seamless, and 1s conveniently described as a substantially seamless sheet metal envelope. The method of forming the substantially seamless sheet 'metal envelope is preferably acoordin to one or another of the inventions describe in my Patent 1,599,510, fgranted Sept. 14, 1926, and my a plication or PatentSerial No. 730,632, fi ed August 7, 1924. The'form of envelope shown. is conveniently made from a thin 'walled tube formed by drawing or extrusion, the closed end of.

which is perforated and formed with a neck 16 thereon, and the open end of which in spun and, formed with a neck 18 thereon, the section bein open through the necks 16 and 18 to suitab e manifolds or joining portions 20, 21, as shown in Fig. 5.

The portions 14 are formed separate from the envelope, and are provided with projections 25 for increasing the effective radiating surface of the radiator sections, and for baffiing the air current flowing over said sections.

The portions 14 are referably in the form of light sheet metal s ells formed by press- PATENT FF CE;

Fig.13being a top plan view 0 Fig. 11

with the upper piping ustrating another emates a radiator section comprising an ing or stamping sheet metal. The shells are conveniently formed in two portions, adapted to surround the envelope, and preferably attached at their free edge portions by rivets or the like, as indicated at 27.

As illustrated in Figs. 1 to 5, inclusive, and 14, the projections 25 are conveniently for ed by pressing or bending up portions of tlie sheet metal, the bent-u portions being conveniently cut out on t ree sides, as indicated at 29. The projections are, in this form, narrow strips 30 of outstanding sheet metal running across the face of the shells of which they form a part. The projections may run straight across the shells, as indicated in Figs. 1 and 2, or diagonally across, as illustrated in Figs. 3, t and l t.

The efl'ective radiating surface of the composite section is increased by the amountof surface of the strips 30. The projections 25 also act to battle or disturb the current of air flowing over the radiator sections, so as to increase the efficiency with which heat is imparted to the air to be heated by the radiator.

As illustrated in Figs. 6 to 10, inclusive, the projections 25 on the portions 14: may be formed by embossing or drawing the surface of the sheet metal, these projections 25 being conveniently elongated transversely of thesection, and running straight across as shown in Figs. 6 and '7, or across at an incline as shown in Figs. 9, 10 and 12. The ends of the projections are preferably open, as indicated at 28.

The drawn projections 25 act similarly to the cutout projections 25, to increase the radiating surface, and also to badlc the air flowing over the radiator sections.

The shells ll may be formed entirely by press operations on sheet metal, and may be very rapidly, readily and cheaply formed, and a composite radiator comprising a thinwalled envelope and shells lat may be very cheaply and rapidly manufactured.

The sheet metal shells surrounding the envel pes may be used in connection with other forms of radiator sections for increasing the radiating effect of such radiators, or for strengthening the same, or for both purposes, and constitute a cheap and eiiective means for these purposes, capable of rapid and economical manufacture.

Figs. 11 to 14, inclusive, illustrate embodiments of the invention especially adaptable for light metal radiators using relatively high pressure heating fluid.

In these embodiments the projections 25 on the shells are made long enough (or high enough) for the projections 25 on adjacent sides of adjacent sections 14 to contact, as illustrated most clearly in Figs. 11 and 14. The projections 25-may be of any suitable form, but are preferably elongated and arranged to run diagonally of the shell, simineaaeac lar to the showing in Figs. 3 and 9, the pro jections 25 on two shells 14 in contact being preferably so arranged that the lines of contact run criss-cross, as shown in Figs. 11 i and 14.

Suitable means are provided forsustaining the high pressure of the heating fluid within the sections or group of sections tending to expand the sections. This means may conveniently comprise rigid end plates or heads l0, oined together by tension rods ll, or the like, and arranged to bear on the outer flatsides of the end sectionsin a group of sections arranged with the flat sides adjacent and in contact, as best illustrated in Fig. 13.

The groups of sections illustrated in Figs. 11 and 13 are well adapted to serve as heating units in industrial heating, drying and air-conditionin apparatus.

The surrounding parts 1% may, however, be so formed as to sustain deformation stresses in the envelo e 12 due to high internal fluid pressures independently of adjacent sections or other means, and the projections 25, particularly in the form of transverse ribs, ma constitute strengthening means, or a ditional strengthening means for this purpose.

Where a group of sections '12 are pro vided with rigid heads or end pieces l0 tied together, the shells 1% may be mere intermediate parts without connection one with another.

The invention may receive other embddi 1 ments than those herein specifically illustrated and described.

llhat is claimed is:

1. A radiator adapted for use with relatively high pressure heating fluids comprising composite sections, said sections each comprising a seamless light metal envelope deformable under the pressure of heating fluids used therein, and a surrounding portion adapted to restrain said deformation I of said light metal envelope, said surrounding portion comprising a pressed metal shell having strengthening ribs for stifiening the same, the composite sections being so assembled that the ribs on adjacent faces of adjacent sections are in contact.
