UNI-TED STATES HUGO KURTZNEB, 0F CLEVELAND, OHIO.
RADIATOR.
Application filed April 3, 1924 Serial No. 703,976;
To all 1 :72am it may concern:
Be it known that I, HUGO. KUn'rzNEn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Radiators, of which the following is a specification.
This invention relates to in'iproveuients in radiators, particularly that type employed It is likewise an object to provide a radi-- ator of this character wherein the units are each made up of metal sheets of heat conducting material so folded as to form a plurality of air passage ways and create upon assembling a set of such units, water channels arranged horizontally as well as vertically.
Other objects will be in part obvious and in part pointed out hereinafter.
In order that the invention and its mode of operation may be readily understood by persons skilled in the art, I have in the accompanying illustrative drawings, and in the following detailed description based thereon set out one possible embodiment of the same.
In these drawings, Fig. 1 is a fragmentary front elevation of a radiator made up of units constructed in accordance with this invention, the heavy lines in this figure designating the outline of each unit;
Fig. 2 is a detail perspective view of a single unit;
Fig. 3 is a side elevation illustrating the manner in which the horizontal water channels are formed between the units;
Fig. 4 is an enlarged cross sectional view' taken substantially on the line 44 of Figure 3 and Fig. 5 is a detail cross sectional view of a si e suit p ior to the final P g to= of copper or the like material.
gether of the sheet. to form the finished unit.
Having more particular reference to the: drawings in which similar characters or references designate similar parts, this improved radiator may be broadly stated as comprising a set of independently formed units each having formedtherethrough air passages and having the walls on all sides stamped inwardly, intermediate points near the opposite ends. As is clearly illustrated the assembly of units constructed in this manner results in the formation of both vertical and horizontal water channels thus greatly increasing the efficiency of the radiator.
Each unit 6 is formed from astrip 7 of heat conducting sheet metal, preferably This sheet is bent at right angles in opposite directions at points spaced from the center of the sheet thus forming the central dividing wall 8 of the unit. At points spaced from the previously indicated bending point the metal is again bent right angularly forming opposed side walls 9 which are arranged in parallel relation with respect to the aforementioned dividing wall. portion of this sheet is then bent at right angles with respect to these side walls 9 then inwardly and again outwardly into a position whereat the ends contact with side walls. This bending and folding operation results in the formation of a unit whose four sides are of equal dimensions and which includes a set of four parallel air passages 10.
As shown in Figures 2, 3 and 4 of the accompanying drawing the ends 11 of each unit are of greater cross sectional area than the remaining or intermediate portions, the purpose of this being to provide water channels entirely around and between all of the units making up a. radiator.
In constructing a radiator of units made up in the manner just outlined, the usual method is employed, the units being dropped into a frame and clamped together after which the ends are dipped for the purpose of soldering the several units and rigidly connecting them. Due to -the individual construction of these units it is apparent that replacement of any damaged unit or units may be accomplished without tlis u bing' the remaining struct r and Each remaining while I have illustrated in the drawings, a unit wherein is provided a set of four air passages, it is to be understood that through certain modifications a greater number of passages may be readily provided. Certain other minor changes in details of construction may be resorted to and such of these changes as fall within the scope of the appended claim, I consider within the spirit of my invention.
I claim:
A radiator unit formed of a single sheet of metal substantially rectangular in configuration, said sheet being bent right angularly in opposite directions at points spaced from the center to form a central wall, said sheet being again bent right angularly at points spaced from the first named bending points to form side walls parallel with the central wall, the side wall portions being bent right angularly toward the first bending points to form Wall portions co-acting with the portions between the first and second bends to form additional side walls, the sheet then having its ends bent inwardly upon opposite faces of the central wall to the medial point of the latter, then bent outwardly in opposite directions to form short walls at right angles to the central wall, and lastly, said sheet being bent at right angles to the short walls and upon the inner faces of the first named side walls and terminating at the third named bending point, the ends of said unit being of greater area than the intermediate portions.
In testimony whereof, I affiX my signature.
HUGO KURTZNER.
