To all whom it may concern:

Be it known that I, ROBERT J. KIENDL, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following is a specification.

Tlplis invention relates to a radiator which is more particularly designed for cooling the water of automobile gas engines although the same may also be used for other purposes.

It is the purpose of this invention to produce a radiator of this character which can be manufactured at low cost, which will cool the water thoroughly and rapidly and which is not liable to leak under the severe usage to which such radiators 'are subjected.

In the accompanying drawings consisting of Q sheets: Figure l is a front elevation of an automobile radiator embodying my invention. Fig. 2 is a fragmentary vertical longitudinal section thereof in line 2-2, Fig. l, on an enlarged scale. Fig. 3 is a vertical cross section in line 3-3, Fig. 2, on

a still larger scale. Fig. l is a fragmentary horizontal section, on an enlarged scale, in line 4l4, Fig. 2. Fig. 5 is an oblique section, on an enlarged scale, in line 5-5,.

Fig. 2. l

Similar letters of reference indicate corresponding parts throughout the several views.

l represents the upper inlet header' or water box, 2 the lower outlet header or water box, and 3, 3 the upright side pieces connecting the upper and lower headers. l Between the side pieces the upper an lower headers are connected by a plurality of upright water tubes 4, which embody my invention and which are separated by intervening air passages Each of these tubes is preferably constructed as follows: G, 6 represent two upright walls constructed preferably of sheet metal strips and arranged parallel with each other in a direction fore and aft of the radiator. At their upper and lower ends these side walls are preferably connected with; the bottom 7 of the upper header and the top 8 of the lower header by means of outwardly turned horizontal flanges 9 arranged on the ends of said walls and secured by solder or otherwise to said bottom and top, as shown in Fig. 3. At their vertical longitudinal edges the side walls of the tube 'are connected with each other by binders or strips 10 each of which is preferably constructed of sheet metal and seamed or interlocked with a corresponding pair of longitudinal edges of the side. walls, as shown in' Figs. 4 and 5; A

Each of the side walls of the tube is provided with a plurality of water channels or grooves 11 on the inner side of the wall which are preferably formed by providing this wall with a plurality of outwardly projecting hollow beads or corrugations 12. The channels of one wallof the tube incline in one direction and the channels of the other wall incline in the other direction. The relative arrangement of these channels is such that each of the channels of one wall, except those near the ends thereof, is horizontally and transversely in line and communicates with the adjacent ends of the channels in the channels of the other wall.

The ends of each channel arepreferably eni larged, as shown at 13, in Figs. 2 5 so as to prevent the flow yof water from being retarded as it passes around the edge of the partition from a channel on one side of the partition to a channel on the opposite side thereof. f

Between the walls of each tube is arranged a partition or web 14C which is preferably constructed of a strip of sheet metal and secured in place by solder or other means, or the same may be held in place by being clamped between the side walls of the tube. This partition terminates atfits vertical longitudinal edges short of the vertical longitudinal edges of the walls -so that it eX- tends across the inner sides of the channels or grooves of the walls intermediate the ends thereof and thereby interrupts communication between the central parts of the channels of both walls but permits these chan- 'nels to communicate with each other at their duits communicate at their upper and lower ends with theupper and lower headers so that the water is conducted from the upper to the lower header' and exposed in thin or small streams to the cooling' effect of the air which contacts with the outer side of the walls of the tube. The water is thus quickly and thoroughly cooled or reduced in temperature inasmuch as it is compelled to take a tortuous course in passing through the tube, thereby subjecting all the water for a considerable length of time to the cooling action of the air before escaping to the outlet header.

The corrugation in the walls of the tubes may be produced by-stamping at low cost from the same dies and are simply reversed to produce rights and lefts having their channels inclihing in .opposite directions, thereby reducing the cost of manufacture.

Inasmuch as only the longitudinal edges of the walls need to be connected and this can be reliably done by means of the binding strips, the possibility of leakage is reduced to a minimum.

I claim as my invention:

A radiator comprising upper and lower headers and a plurality of tubular sections connecting said headers, each of said sections having two side Walls which are connected at their vertical edges, and a partition arranged between said Walls and stopping at its vertical edges short of the vertical edges of said walls so as to form connecting passages at opposite vertical edges of said Walls, each of said walls being provided on its inner side with a plurality of inclined channels the upper ones of which extend :umane from the upper header to connecting passages at one of the vertical edges of said walls, the lower ones extending from lthe lower header to connecting passages at the other vertical edges of said walls, and the intermediate ones extending from the connecting passages at one of the vertical edges of the Walls to the connecting passages at the other vertical edges of said Walls, and the channels of one of said wallsinclining in a direction opposite to the channels of the other wall ,and the two sets of channels communicating with leach other lat their extremities, whereby the water in passing from the upper to the lower header is caused to move in a substantially spiral path and successively along opposite sides of said partition and each of said channels being provided adjacent to the vertical edges of the partition with an enlargement.

Witness'my hand this 15th day of July,

ROBERT J. KIENDL. Witnesses:
