This invention relates to radiators suitable for use in connection with internal combustion engines using cooling water.

Radiators for water cooled internal combustion engines require the passage of water in one direction through one set of passages and the passage of air through other passages in another direction. For high efficiency it is desirable to have low resistance to air-flow l0 and also to flow of water, and yet to divide up the water-flow and air-flow into sufiieiently small streams so that the water may be cooled rapidly, the heat being conducted to the air through thin metallic walls. It is also of great importance that-every part of the radiator be active in dissipating this heat.

There are two principal types of radiators, one the honeycomb type of radiator, made up of corrugated sheet metal strips suitably spaced. apart to form corrugated conduits for the water, the other beingthe fin-and-t ube type made up of a number of spaced apart flat sheets of metal through which are passed a number of tubes to conduct the cooling water. The assemblying of this form of radiator has contributed considerably to its cost. The present invention relates to a radiator which, insofar as appearance and operation are concerned, resembles Y. the fin-an'd-tube type, but which is made up in an entirely different manner, by which the expense of assembly is very materially reduced. An'object of the present invention is to provide an improved radiator wherein parts may be readily brought together and assembled into a cooling seetionand thus into a com- M necessary in making the conduits watertight;

Another object of the invention is to provide a radiating section in which water conduits are integral with their supports wherebv there is a rapid transfer of heat energy from the tube to the surrounding air.

Other objects of the invention will be apparent as the invention is described in detail below. a

In the accompanying drawings there is shown, for the purpose of illustrating the invention, a completed radiator made in accordance with the present invention, together with several modified forms of radiator elements which may be used in accordance with the present invention. In the accompanying drawings Fig. 1 is a front view of a complete radiator according to my invention;

Fig. 2 is a horizontal section taken on the line 22 of Fig. 1;

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1;

Fig. 4 shows a method of fastening the sections together;

Fig. 5 is a plan view of a portion of one form of radiator element; Fig. 6 1s a plan view of a modified form of the element;

' Fig. 7 .shows a detail of a slightly further modified form of element;

Fig. 8 is a section showing the assembly of a number of elements and taken on the line Figs. 9and 9A illustrate further modifications of the element.

Figs. 6, 7 and 8 illustrate a completed strip or element of material. It will be seen that the strip 60 has a number of regularly'spaced depending tubes 61, and holes 62 intermediate the-tubes 61. The severed material has been'bent down to provide fins or deflectors 63 or 63 (Fig. 7). The tubes 27 are given a slig11t taper, and, if desired, the punch and die mechanism may be such as to give the tubes an intermediate shoulder such as shown at 64'and a smaller inwardly directed ledge 65 at the bottom end of the tube. It is preferable to locate the shoulder-64 half-way between the ledge 65 and the upper surface 66,

r for then the tubes reinforce one another.

Fig. 8 shows the way of assembling elements such as above described into a cooling section. The str p of metal with the tubes and with or without the additional unchings is cut into pieces ofthe proper ength,

them-aterial is deformed to provide the finsor deflectors, these deflectors will operate to stir the air passing through the cooling section so as to bring it intolintimate contact with the outside of the tubes.

The structures heretofore disclosed have contemplated the use of round tubes, but the configuration of the tube is not essential, as shapes other than round may be used. Two

' such shapes are shown in Figs. 9 and 9 in which the tubes 68 and 69 are oblongin shape. They may be made up in a manner similar to the method described with respect to the round tubes.

The cooling section which has been made up in the manner above described is now ready to be placed in a frame to make up a finished radiator. One form of such a radiator will now be described. A strip of metal 170, suit-ably punched, is laced between the upper two of the neste elements,

and to this strip may be fastened'the up er tank 171. A lower tank 172, with suita ly located apertures in the upper part thereof, is passed over theprojecting tubes 174 of the bottom section. A very convenient method.

of fastening these parts together is shown in Fig. 4, according to which rods 175 are passed down through two or more of the 40 tubes 67 and soldered inplace as shown at 177. The soldering of these rods at both top and bottom to the upper and lower elements of the cooling section permanently fasten together all parts of the cooling sectlon. In order to protect the pro ecting ends 178 of the elements of the cooling sect on, there may be provided, if desired, a strip 179, to which the ends 178 may be soldered. A sultable frame 180.may be provided, to give the radiator a finished appearance; and to make the structure more rigid, brackets 181 and 182 are used, reaching from the tanks to reinforce the cooling section. 7

Sometimes it is desirable to remove excess metal; and then one can punch holes between the tubes 27 as shown at 27 in Figure 5.

Radiators made up in accordance with the smaller number of tubes or with .a much smaller radiator than is possible in the ordinary fin-and-tube type 0 radiator, in which the metallic parts cannot be brought into' good thermal contact. As the use of solder is not, necessary to make the device watertight, it is of course obvious that the troubles incident to soldering have been eliminated, and the elimination of these soldered joints makes it possible to readily take the radiator apart for purposes of repairs, replace the worn elements with new ones, and restore it to service.
