My invention relates to radiators, and 'par- -tieularly to panel radiators.

In heating rooms, a 'better distributionof heat is obtained Where convection currents are relied upon for distribution'of heat from a radiator to the lremote parts'o-f the room thanis obtained Where radiation, alone, is relied upon. The temperature o'flthe lradiator must be maintained considerably aboye @the I 'temperatureof theremote Aparts of the room, Where radiation is relied upon inorder'to see'ure the desired average temperature. 1n suoli cases, the radiator is often too hot to permit persons to Iremain near it.

Radiators heretofore-used have genera'lly presented-an unsightly appearance dueto the Vpresence o-f a large number of thin ends of yradiator columns and intervening spaees which are usually in shadow :and servea's dust 29 vaccumulatore.

I provide 4a radiator unit `having a substan- #tial-ly Vcontinuously exposed surface `of 4considerable area. This exposed surface may-be o ornamental -to harmonize with 'the furniture 2 and Walls of a room. The lrear surface is provided with a series of grooves constituting' passageways or stacks for t1 ne lmovement of I convection currents behind the radiator limit.

l This surface usually faces awafll of the room. A 'l-"he ends of the radiator units ta'persli'ghtly Afrom the exposed face, and form continuous lcorners with the exposed surface from lthe 'top tothe bottom of the radiator fso that aA 'plu- -rality of radiator sections maybe placed 'end Y to 'end forconstituting yanasse'mbled radiator. The subject matter of this easeis related #to that of my copending application,I'Serial Number 308,274, led September 1&5-, 1928, which has nonT matured `into Patent No.

Referring to the drawings, aradiatorQ `com-prises `a plurality A-of radiator sections 4 placed in iend-'to-end relation. The radiator sections are conneotec'l'byvpipe nipples v5 'eX- 'tending `into Aopenings 6 disposed aft lthe to'p and Abottom of `each radiator section, such manner fof connection being AWell `known in the art..

Each 'radiator section 4comprises a central 'portion 7.the "outer surface 'of which is oon- 'situtedfby a continuousy'walfl Stliat nries in :substantially a single plane. The surface ofthe WallS is provided 'with `small grooves 9 'and rai-sed ].iortions "10 to "correspond tothe joints formed between adjacent sections and presenta pan eled'a ppea ra'n ce. ylith th'is'eonstruction, a number of radiator sections may -be fastened "together Vin end-'to-end relation andthe `entire `outer `surface of the radiator present substantially the appearance "that would be given were Va plurality of 'short 'see- .tions used, Whose ldges i'termin'a't'ed at .the *groovesY 9. p

The i'nner'surfaees of `vthe body portion '7 between the portions 1l lare vprovided 'with l ay pluralityVY of outwai diy 'extending 'ribs 15. The ribs ldefine grooves Aor `passages 16 lthrough "which A ai'r currents inove'by Convection The fi'rregl'ilar contour deli-ned bythe ribs 15 increases 'the rer "surface ofA the radiator fse'c'ti'on'and -a fsu-res t fthe'air in moving over it YYabsorbs "ftheinr orpor-t'ion of ftheheat 'by convection rather than by radiation. T he "heating fof the 'room by radiationinrlie forward volves a thermal gradient throughout the room, from the radiator to the most remote part of the room. A more nearly uniform heating of the room is obtained where the air is passed frequently over the surface of the radiator by convection currents. If it is desired to maintain the same temperature in a room, it is not necessary to maintain the radiator at as high a temperature where convection currents are relied upon as where radiation is relied upon.

Clamping bolts 18 extend longitudinally of the radiator by which the radiator sections 4 are held together. As shown in Fig. 5, brackets 19 extend into the spaces 19a formed between opposing walls of two abutting sections and engage the hubs for the nipples. The brackets 19 are provided with notches 2O for clearing the clamping bolts 1S and are secured toan adjacent wall or other support. Where brackets are used to support the radiator, the latter is particularly adapted for mounting in a recess 21 -in a wall 22.

While I have shown the use of two brackets in this figure, it is to be understood that the lower bracket may be omitted if desired. A space is left beneath the radiator and air currents move upwardly between the wall 22 and the flanges 15 and inner surfaces of the wings 11 of the radiator. The air moves across the top of the radiator and escapes beneath an overhanging portion 23 of the wall. The radiator may be used alone or with various types of enclosures and space filling fittings having provision for the passage of air cnrrents through the radiator, of which there are many on the market. An example of such a construction is shown in my copending application.

Referring to Figure 4L, the radiator may also be mounted on legs 24 resting on a floor 25.

Each radiator section is adapted to be used as a complete radiator. By assembling the radiator sections in endtoend relation and connecting them, a radiator of any suitable length is provided.

While I have shown and described certain preferred embodiments of my invention, it is understood that the invent-ion may be otherwise employed within the scope of the following claims.

I claim:

1. A radiator section comprising a hollow L 'fa e ex enc ino` in body portion having a suii c t l g substantially a single plane, the opposite sur face of the body portion being provided with ribs defining a plurality of grooves, and hollow end portions of greater width than the body portion and ribs, said end portions having continuous walls extending at substantially right angles to the continuous surface of the body portion and having openings for the reception of pipe connections.

2. A radiator section comprising a continu- 'body having hollow wings at each end thereof and a hollow panel portion between the wings, the space 1n the wings and the space in the panel being continuous to permit the flow of 'fluid therethrough, the front surface of the body extending substantially in a single plane, the rear face of the panel portion between the wings having heat dissipating projections thereon.

4. A radiator section comprising a hollow body having hollow wing portions at each end thereof and hollow panel portion between the wings and connecting the wings, the interior of the body providing a continuous fluid circulating space, the front surface of the body extending substantially in a single plane, the rear face of the panel portion of the body between the wings being corrugated, said wings having nipple receiving openings in the end faces thereof which are disposed rearwardly of the panel portion of the body.

5. A radiator section comprising a body portion having front and rear walls spaced from each other, the exposed surface of the front wall extending in substantially a single plane, the rear surface of the body portion being provided 1Vith ribs defining a plurality of grooves, and hollow end portions of greater width than the body portion, the space in the end portions communicating with the space between the front and rear walls of the body.

6. A radiator section comprising a body portion having spaced front and rear walls, the exposed surface of the front wall extending in substantially a sinfrle plane, the exposed surface ofthe rear wall of the body portion being provided with ribs defining a plurality of grooves, and hollow end portions of greater width than the body portion and ribs, the space in the end portions communicating with the space between the walls of the body, said end portions having walls extending at substantially right angles to the continuous surface of the body portion.

In testimony whereof I have hereunto set my hand.
